Purpose: There's concern in recent years that opportunities to learn how to prepare and cook food are in decline, leading to reduced skills, knowledge and confidence. In order to address this, several community-based educational initiatives have been developed, however, these seldom specify which behaviour change techniques (BCTs) are used, making it difficult to assess which educational ingredients are successful. Therefore the purpose of this study was to: (1) design a cooking skills intervention with four conditions which incorporate the use of relevant BCTs, and, (2) determine, via a cooking skills intervention with adults, which BCTs are most effective in enhancing their intention to cook a meal from basic ingredients.

Methods: The intervention design was underpinned by Social Cognitive Theory, systematic instruction and Bloom's Taxonomy Revised. 141 female participants aged 20-39 years from the Island of Ireland were randomly assigned to one of four conditions in which they were given varying guidance on how to cook a lasagne from scratch. Condition 1, ‘recipe only', mapped onto the ‘providing instruction on performance' BCT; Condition 2, ‘video demonstration (plus recipe)', mapped onto the ‘provide instruction' and ‘model/demonstrate behaviour' BCT's; Condition 3, ‘video segments (plus recipe)', mapped onto the ‘provide instruction', ‘model/demonstrate behaviour' and ‘set graded tasks' BCT's; and Condition 4, ‘free access to video segments (plus recipe)' mapped onto all the aforementioned BCTs plus the ‘behavioural practice/rehearsal' BCT. Pre- and post-intervention data was collected on the participants' likelihood of cooking the meal from scratch together with their confidence, enjoyment and perceived difficulty in cooking.

Results: Pre-intervention measures were not significantly different between conditions. Significant increases in both the likelihood of cooking and confidence in cooking occurred in all conditions ( P 0.05). Regression showed that pre-intervention measures accounted for 32% of the variance in likelihood of cooking post-intervention, and that the addition of post-intervention measures (i.e. confidence, enjoyment and perceived difficulty) explained an additional 10%. Post-intervention enjoyment and confidence in cooking were positively associated with likelihood of cooking.

Conclusions: Providing opportunities to learn how to prepare and cook food are vital for increasing cooking intentions at home.

Purpose: Cross-sectional studies have linked food-related parenting practices with dietary intake and weight status among early adolescent children (9-14 yrs). The purpose of this study was to determine if a 6-lesson cooking intervention for parent/child pairs could improve parenting practices to increase child vegetable intake.

Methods: A 6-week (2 hrs/wk) cooking intervention adapted from the Cooking Matters for Families program was implemented on 45 parent/child (9-12 yrs) pairs. During the intervention, parents were encouraged to employ a new behavioral strategy each week at home to enable increased child vegetable intake. Strategies included having the child help prepare vegetable dishes, using a plate allocating vegetable placement, strategically placing vegetable serving dishes at the table, etc. These strategies were modeled during shared meal times at the cooking intervention classes. A weekly questionnaire was used to assess habitual use of the strategies at home and analyzed with paired t-tests.

Results: Parents were primarily women (97%), with 50% having a high school diploma, between 30-39 years old, 95% non-white, and all using public food assistance programs. Difficulty ratings for performing the strategies ranged from 1.3 to 2.0 (1 = not hard, 2 = a little bit hard). Scores on items assessing habitual use of the strategies improved slightly over time. Barriers to use of the strategies included lack of time, lack of availability of vegetables at home, children not liking vegetables, fear of wasting food, and that some suggested strategies atypical practices for families.

Conclusions: Overall, the strategies employed were easily integrated into the cooking classes and provided opportunities to model use in the home. Parents felt the strategies were easy to use; however some parents reported barriers to using several strategies. Cooking intervention programs may be a useful medium for education and promotion of parenting practices to improve child food intake behaviors.

Awards:

Background: The Back to Basics Cooking Club and Healthy Lifestyle Program (B2B) is an evidence-based, family focussed, healthy lifestyle program designed for conduction as an after-school activity such as a cooking club for children.. Initial pilot testing found B2B to be feasible to be conducted after-school in a community setting for primary school aged children. Through the development of a train-the-trainer supporting program, B2B was implemented across a number of schools in areas of socio-economic disadvantage in the Hunter region of NSW Australia.

Aim: The current evaluation describes the impact of implementing the B2B program across five primary schools (n=77 children) in Canberra, ACT, Australia during 2 school terms at three time points, baseline, immediately post-program (after 10 weeks) and a further 3 months after completion. In addition process evaluation results are reported.

Method: B2B program outcome measures were assessed through standardised evaluation questions modified to suit the purpose of ACT Health. The outcomes were assessed by three groups: trained programme facilitators, parents of children and the children themselves, through fixed and open ended questions. B2B targeted children (5-12 years) and their parents/guardians and included 5 x 90mins after-school cooking sessions, during one school term.

Results: Overall facilitators felt well prepared for sessions, and found it easy to conduct the program having participated in the face-to-face training and by following the detailed session outlines. Parents and carers of children felt B2B was valuable and that having their children participate in B2B led to a positive impact on their family eating habits, enjoyment of family meals and their subsequent efforts to involve their children in cooking at home. The B2B program achieved a sustained increase in self-reported vegetable intake in primary school aged children, up to three months after participating in the program.

Future recommendations included additional website resources to support practical cooking skills, additional parent activities, more frequent classes and potential modifications for schools with limited space..

Conclusion: The B2B Program when conducted within the after-school care environment had a major impact on improving children's vegetable intakes up to three months after completing the program and was considered enjoyable.

Purpose: Effective, low-cost approaches are needed to enhance dietary behavior change. While both video and tailoring technology have been effective interventions to improve diet, these approaches have not been combined to study the effectiveness of tailored videos. The purpose of this paper is to discuss the results of Good For You!, a randomized trial that tested the efficacy of innovative, individually tailored videos in helping worksite employees decrease dietary fat and increase fruit and vegetable (F&V) intake.

Methods: Worksites were matched on approximate size, type of company and workforce composition. Employees were randomized to one of three experimental conditions: Non-Tailored written information (NT), Tailored Written information (TW), or Tailored Written + Tailored Video (TW + TV). Evaluation was conducted at baseline, 4 and 7 months. We used the NCI Fat Screener and an adapted Food Habits Questionnaire (FHQ) to estimate fat intake and fat-related behaviors, the NCI F&V Screener and F&V Habits Questionnaire (FVHQ) to measure F&V intake and behaviors. Generalized linear models were examined for all outcome measurements.

Results: 2525 worksite employees were randomized. At 4 months, dietary fat intake decreased significantly more for TW (-2.65%) and even more for TW+TV (-2.98%) compared with NT (-2.12%). FHQ scores decreased significantly more for TW+TV. Fruit intake increased the most for TW+TV. Both TW (1.35 cups) and TW+TV (1.65 cups) increased F&V intake significantly more than NT (0.80 cups). TW+TV showed the largest increase in F&V behaviors on the FVFQ. At 8 months, dietary fat change continued to be better for TW+TV (-3.29%) than NT (-2.83%). F&V intake changes were no longer significant, but the trend indicated higher increases for the TW+TV group compared to the TW and NT groups based on both the screener and FVHQ measures.

Conclusions: The tailored intervention participants were more likely to decrease fat and increase F&V intake. The TW+TV group was generally the stronger of the two tailored interventions, demonstrating the promise of tailored video as an intervention to change eating habits. Future studies should explore "third generation" channels for delivering tailored video interventions including the internet and smart phones in addition to DVDs.

Purpose: The internet provides a good platform to deliver physical activity interventions to large numbers of people at low cost. Computer-tailored advice in web-based physical activity interventions has shown to improve engagement and behavioural outcomes, but does not provide participants with accountability or social support. It is unknown whether additional video calls with a behavioural expert would improve the effectiveness of computer-tailored advice. The purpose of this study was to determine the effectiveness of a web-based and computer-tailored physical activity intervention with and without the addition of a brief video-based coaching session in comparison to a control group.

Methods: A total of 240 participants were randomly assigned to one of three groups (tailoring + coaching, tailoring-only and wait-list control). The tailoring + coaching participants received an 8 week computer-tailored web-based physical activity intervention (‘My Activity Coach') with four 10 minute coaching sessions with a behavioural expert over an online video calling program (e.g. Skype). The tailoring-only participants received the same intervention without the coaching sessions. An intention-to-treat linear mixed model analysis was conducted to compare self-reported physical activity from pre to post intervention (week 9) by group.

Results: Overall retention was low (55%) and a low percentage of tailoring + coaching participants completed a coaching call (21%). Physical activity in minutes per week improved from pre to post intervention in all groups (tailoring + coaching, M=150, SD=240, tailoring-only, M=123, SD=242, wait-list control, M=34, SD=172). There was a significant interaction between group and physical activity outcomes F=(2,88) 3.02, p=.05. The physical activity increase in the tailoring + coaching group in comparison to the control group was significant (p=.02), and the physical activity increase in the tailoring-only group in comparison to the control group was approaching significance (p=.06). No significant difference was found between the tailoring + coaching and tailoring-only groups.

Conclusions: Findings support the effectiveness of providing online coaching and computer-tailored advice in a web-based physical activity intervention. However, future studies with larger sample sizes and which promote a higher participation in the coaching sessions are required to determine whether online coaching can improve intervention effectiveness over computer tailored advice only.

Purpose: A recently developed theory-driven, web-based, interactive computer-tailored intervention aimed at changing sitting at work was found to be effective in decreasing self-reported occupational sitting compared to a generic advice and no advice group. The aims of the present study were to examine 1) the effect of the intervention on psychosocial factors and 2) whether changes in these psychosocial factors and the completion of an action plan mediated the effect of the intervention on occupational sitting.

Methods: A randomized controlled trial examined the effects of computer-tailored advice based on different aspects of the Theory of Planned Behaviour, Self-Determination Theory and Self-Regulation Theory among Flemish employees (n=213). At baseline and 1-month follow-up, participants self-reported their sitting time at work, and their knowledge, attitudes, self-efficacy and social support to change occupational sitting. Website statistics provided data on the completion of an action plan among intervention participants (yes/no). The intervention effect on psychosocial factors was examined conducting a repeated measures MANOVA. The mediating role of the changes in these psychosocial factors and action planning was examined using the product-of-coefficients test of MacKinnon based on multiple linear regressions. All analyses were controlled for age, gender, education, hours spent at work, employment duration, BMI and physical activity.

Results: The intervention was successful in increasing knowledge about health-related aspects of sitting (p=0.037), but had no effect on the other psychosocial factors. The increase in knowledge was however not found to be a mediator of the effect of the advice on occupational sitting. Fifty-four intervention participants (69.2%) completed an action plan. The completion of an action plan was found to be a significant mediator of the intervention effect on occupational sitting (85.4% mediation; p

Purpose: Computer tailoring is a technique that provides highly personalized information to respondents in order to adopt a healthy behavior. Yet, most of the studies have used only text based feedback using PC's. This presentation we will outline the effects of two innovative studies comparing: 1. The efficacy of text-based and video based computer tailoring on obesity prevention (study 1) and 2. The efficacy of a computer tailored eHealth and mHealth interventions on physical activity (study 2).

Methods: Both studies were developed on the basis of the I-Change Model that acknowledges the importance to raise awareness about one's own health behavior, to develop positive attitudes, social support and self-efficacy and to enhance self-regulation via the development of action plans. Study 1 (N=1419) is a RCT in which both the video and text based version (with 6 weekly sessions) were compared to a control condition. Study 2 (N=372) is a RCT in which the effects of physical activity tailored program delivered via 5 sessions using eHealth (the PC) or mHealth (smartphones) were compared with a control condition.

Results: For study 1 only the video version resulted in significant changes after 6 months on BMI, whereas the video version and the text version influenced daily energy intake. No effects on physical activity were found. The video version had the best appreciation. For study 2 the results show that the eHealth condition had the lowest drop-out, the highest level of use, a better appreciation and a borderline higher level of physical activity in comparison to the other conditions.

Conclusions: The video version of the web-based computer tailored program aimed at obesity prevention was the most effective program, and the best appreciated. mHealth programs are not necessarily better than eHealth programs, and future research needs to identify the condition under which selection of a specific modality is indicated.

Objective: This study aimed to obtain insight into the influence of the home and community environment on preschool children's physical activity (PA), from the perspective of parents/caregivers. The results of this study are being used in the development of an intervention to promote PA and gross motor skills in South African (SA) preschool children.

Methods: 198 parents/caregivers (aged 39.2±12.7y) of preschoolers (aged 4.8±0.7y) were recruited from 10 urban (n=55) and rural (n=143) preschools in SA. Parents were asked to complete an adapted questionnaire based on the Healthy Active Preschool Years (HAPPY) and the Preschool-aged Children's Physical Activity Questionnaire (Pre-PAQ).

Results: Mothers (69%) and grandmothers (24%) made up most of the sample. 50% of participants agreed that preschool children should be active for 3 hours daily, while 34% reported that 3 hours of PA is ‘too much'. 77% reported that they were satisfied with their child's current PA levels, and 81% reported that their children are sufficiently active for their health. 76% of participants disagreed that television viewing could have an effect on their child's health, although 52% were not confident in saying ‘no' to children's requests to engage in screen time. 81% of participants felt that their children's energy levels were not a barrier to PA, and 87% reported that they believe that their children enjoy being active. A small number of participants (8%) felt that their children were too overweight to participate in PA, and only 9% reported a lack of ‘skills' as a barrier to PA. 66% of participants reported that there were insufficient play areas in their community, with 65% of parents did not feel existing facilities were safe. Neighbourhood safety was a concern for 62% of the parents.

Conclusions: Parents/caregivers have generally positive perceptions regarding their preschool child's PA, which indicates that PA could be an acceptable vehicle for the promotion of a broader range of developmental outcomes (e.g. cognitive development) with parents/caregivers. From the perspective of parents/caregivers, there appear to be relatively fewer barriers to PA in the home environment, compared to the community context. These community barriers should be addressed in the intervention.

Objective: To report on process data collected from a large scale randomised controlled trial implemented in Early Childhood Education and Care settings located in areas of disadvantage.

Methods: An 18-month randomised controlled trial is currently being conducted in 43 low-income Early Childhood Education and Care services (children aged 3-5 years) throughout New South Wales, Australia. Services randomised to the intervention group participate in a five-component intervention, designed to be incorporated into their daily routine. It includes structured physical activity lessons (20 min, 5 per week), unstructured physical activity sessions for children, energy breaks (3min, 10 per week), integrated curriculum activities (10 per week) and a home component. Ongoing and bespoke professional learning is offered to all educators. The primary outcome is time spent in physical activity (accelerometry). Process data are collected on a rolling basis and comprise one-day independent observations (3x throughout intervention) and accountability sheets completed daily by educators. Independent observations focus on the length and number of components facilitated, equipment used and educator behaviours.

Results: Process data to date indicates differing degrees of implementation. Independent observations show that approximately 45% of services are implementing the intervention with a moderate to high degree of fidelity, approximately 30% of services are implementing some components of the intervention and 25% of services are implementing few or no components of the intervention. In services where fidelity of implementation is moderate to high, the intervention is embedded into the service daily routine and educators report increased confidence in children in physical activity-related experiences. A number of challenges have been identified by educators including time, space, educator resistance and educator confidence. Differences have been observed between accountability sheets completed by educators and independent observations. A complete analysis of the process evaluation will be presented.

Conclusions: The collection and reporting of process data is important to understand the fidelity of large interventions and inform ongoing professional learning for educators. Support for educators throughout the second half of the intervention will focus on educator's resistance and educator confidence.

Objective: To evaluate a 6-month mobile phone-based dietary and physical activity parental intervention on: a) body fatness and energy intake b) time in sedentary behaviour, moderate and vigorous activities, intakes of fruits and vegetables, snacks, soft drinks, and candy.

Methods: MINISTOP is a two-arm, parallel design randomized controlled trial that has been conducted in 315 healthy Swedish 4-year-olds. After baseline measures, parents were allocated into either the intervention- or control group. A 6-month mHealth intervention consisted of a mobile phone based application (MINISTOP App) to help parents promote healthy eating and physical activity in children. The app is based on the Social Cognitive Theory and involved the delivery of a comprehensive program of information and text messages based on existing guidelines for healthy eating and activity in pre-school children. Parents registered physical activity and intakes of candy, soft drinks, and fruits and vegetables for their child and received feedback through the application. Primary outcomes were body fatness and energy intake, while secondary outcomes are time spent in sedentary, moderate, and vigorous physical activity, physical fitness and intakes of fruits and vegetables, snacks, soft drinks and candy. Food and energy intake (Tool for Energy balance in Children, TECH), body fatness (pediatric option for BodPod), physical activity (Actigraph wGT3x-BT) and physical fitness (PREFIT battery) have been measured at baseline, after the intervention (six months after baseline) and at follow-up (12 months after baseline).

Results: Recruitment was initiated in January 2014 and data collection was finalized October 10th, 2015. Two hundred and eighty-seven (91%) and 280 (89%) completed the first and second follow-up measurements, respectively. We experienced no technical problems, mothers (77%) primarily reported to register behaviors, and 69% reported to use the app at least every third day. We are currently analyzing the intervention effect results and the results will be presented at the ISBNPA conference.

Conclusion: This novel study will evaluate the effectiveness of a mHealth program for mitigating gain in body fatness among 4-year-old children. If the intervention proves effective it has great potential to be implemented in child-health care to counteract childhood overweight and obesity.

Objective: The ToyBox-study developed a kindergarten-based, family-involved intervention to prevent overweight and obesity in European preschool children, targeting four key behaviours related to early childhood obesity, including beverage consumption. The present study aimed to examine the effect of the ToyBox-intervention on water intake and beverage consumption in preschoolers of six European countries and to investigate if the effects of the intervention differed by implementation score of the kindergartens and the parents.

Methods: A sample of 4964 preschoolers (4.7±0.4 years; 51.5% boys) from six European countries (Belgium, Bulgaria, Germany, Greece, Poland, Spain) was included in the data analysis. A standardized protocol was used and parents/caregivers filled in socio-demographic data and a semi-quantitative food-frequency questionnaire. To asses intervention effects, multilevel repeated measures analyses were conducted for the total sample and for the six country-specific samples. To assess differences in water intake and beverage consumption by implementation score in the total sample, multilevel repeated measures analyses were performed.

Results: Limited intervention effects on water intake and beverage consumption were found. However, important results were found regarding prepacked fruit juice consumption, with a larger decrease in prepacked fruit juice consumption from baseline to follow-up in the intervention group compared to the control group. Also a steeper increase in plain water consumption was found in some country-specific samples of the intervention group compared to the control group. However, this was compensated by a decline in plain milk consumption. Implementation scores were rather low in both kindergartens and parents. Nevertheless, better effects were found in preschoolers whose parents had higher implementation scores compared to low implementation scores.

Conclusion: The water component of the ToyBox-intervention can be used to target beverage choices in preschoolers. However, future interventions should create new strategies to improve implementation of interventions.

Objective Physical activity (PA) in pregnancy has been shown to be associated with birth weight, but results of previous studies were inconsistent. Some reported a higher birth weight whereas others a reduction in birth weight of babies of more active women. No previous results were available for associations of sedentary behaviour with birth weight. Maternal weight might also be influenced by PA and sedentary behaviour. We aimed to evaluate the relationship of objectively measured PA and sedentary behaviour with maternal weight gain (GWG) and birth weight.

Methods Data from two prospective studies were combined, resulting in a cohort of 111 pregnant women who were followed from around 15 weeks till 32 weeks of pregnancy. PA and sedentary behaviour were measured with an accelerometer around 15 weeks gestation and in the third trimester. Regression analyses were performed determining the association between time spent in moderate-to-vigorous PA (MVPA) and in sedentary activities with GWG and birth weight. Main outcome measures were GWG between 15 and 32 weeks of gestation, average GWG per week, and birth weight.

Results Early in pregnancy, 32% of women spent ≥ 30 minutes/day in MVPA versus 12% in late pregnancy. Women spend 65% of their time sedentary throughout pregnancy. No significant associations were found between time spent in MVPA or sedentary behaviour with GWG or birth weight.

Conclusions We found no relation between MVPA and sedentary behaviour with GWG or birth weight. The small percentage of women meeting the recommended levels of PA indicates the need to inform and support pregnant women to maintain regular PA, as there seems to be no adverse effect on birth weight and maintaining PA increases overall health.

Awards:

Objective: The first five years of life have been identified as a critical stage in the development of activity behaviours, which have been shown to track into later life. This scoping review aims to assess the literature reporting on physical activity levels in the first two years of life in order to answer two main questions: 1) How is physical activity measured in this age group?; 2) how active are infants and toddlers in the first two years of life?

Methods: A search strategy was employed using PubMed with restrictions only on age and language. After applying exclusion criteria, 20 papers were included in the results.

Results: Seventeen studies used some form of objective assessment of physical activity (accelerometers, actometers, direct observation, doubly labeled water, or a metabolic chamber); while the remaining three relied on subjective assessments (parent reported questionnaires or interviews, and activity diaries). Nine studies exclusively assesed infants (12 months). Only six studies reported physical activity levels and patterns specifically; most included studies measured activity as a covariate or correlate. Therefore much of the reported data was difficult to assess, as results were vague or incompletely described. Where data was reported sufficiently for analysis, results were equally conflicted regarding whether toddlers were meeting recommended physical activity guidelines.

Conclusions: This scoping review re-iterates the fact that more studies need to be conducted which focus primarily on measuring and reporting physical activity levels and patterns in this age group in a comprehensive and standardised way, so that more informed guidelines can be devised and interventions can be designed and implemented where necessary.

Witwatersrand,Johannesburg,Johannesburg,SouthAfrica


Awards:

Objective: To review data and discuss the importance of infant nutrition in relation to later adult outcomes, and the role of maternal behavioural nutrition interventions to optimise infant growth. Method: Review of the literature and pooled data from COHORTS (Consortium for Health Orientated Research in Transitioning Societies)-a collaboration of five birth cohorts from LMICs (Brazil, Guatemala, India, the Philippines, and South Africa), in which mothers were recruited before or during pregnancy, and the children followed up to adulthood. We examined associations between maternal and delivery factors and infant nutrition and adult height, body composition (body-mass index, waist circumference, fat, and lean mass), and cardiometabolic risk factors (blood pressure and fasting plasma glucose concentration). Results: Children of young mothers in LMICs are disadvantaged at birth and in childhood nutrition. Efforts to prevent early childbearing should be strengthened. After adjustment for confounders, children of older mothers have advantages in nutritional status. Extremes of maternal age could be associated with disturbed offspring glucose metabolism. Delaying complementary foods until 6 months, as recommended by the World Health Organization, may reduce the risk of adult overweight/adiposity. Conclusions: The importance of maternal factors and its relation to infant nutrition is paramount to reduce metabolic disease risk in later life. Addressing these maternal nutrition through pre-pregnancy and pregnancy interventions may successfully improve infant nutrition and growth

Awards:

Objective: Maternal nutritional status (MNS) is a strong predictor of growth and development in the first 1000 days of life and may influence susceptibility to non-communicable diseases in adulthood. However, the role of nutrition during this window of developmental plasticity in Africa is unclear. This paper reviews published data to address whether maternal nutrition during the first 1000 days is important for Africa, with a focus on MNS and its associations with fetal growth and birth, neonatal and infant outcomes.

Methods: A systematic approach was used to search the following databases: Medline, EMBASE, Web of Science, Google Scholar, Science Direct, SciSearch and Cochrane Library. Various search terms and combinations were used to select all available studies of any design that described MNS in Africa and/or how it associates with outcomes of interest.

Results: Twenty-six studies met the inclusion criteria for the specific objectives. MNS in Africa showed features typical of the epidemiological transition: higher prevalences of maternal overweight and obesity and lower underweight, poor diet quality and high anaemia prevalence. Maternal body mass index (BMI) and greater gestational weight gain (GWG) were positively associated with birth weight; however maternal overweight and obesity were associated with increased risk of macrosomia and intrauterine growth restriction. Maternal anaemia was associated with lower birth weight. Macro- and micronutrient supplementation during pregnancy were associated with improvements in GWG, birth weight and mortality risk.

Conclusions: Data suggests poor MNS in Africa and confirms the importance of the first 1000 days as a critical period for nutritional intervention to improve growth, birth outcomes and potentially future health risk. However, there is a lack of data beyond birth and a need for longitudinal data through to two years of age.

Purpose: The need for intervention in youth to improve physical activity (PA) levels is very well established, what is less clear however is how to structure such intervention to really meet the needs of the cohort in question. The purpose of this presentation is to highlight how the Y-PATH (Youth-Physical Activity Towards Health) research informed how an evidence based intervention was developed in response to this question.

Methods: Students from four Irish schools (N=256, 12-14 years) were involved in the initial exploratory phase of research, to inform Y-PATH intervention development. Subsequently, an effectiveness trial was carried out (n=174, 12-14 years) to determine effect of the intervention, and to identify aspects for refinement. Finally a one-year cluster randomised controlled trial (RCT) involving 20 schools (n = 524, 12-14 years) was carried out to formally evaluate the intervention. Data collected include PA level (accelerometer and self-report), psychological correlates of PA, BMI, and fundamental movement skill (FMS) ability.

Results: The exploratory phase showed the need for targeting low levels of PA in youth (12% meeting minimum 60 minute guideline), through addressing poor Health Related Activity knowledge and low FMS proficiency. Schools were acknowledged as the most logical environment to access the majority of adolescents, with the PE teacher identified as a trained health professional, available in most schools, that could play a central role. From the literature the need for the intervention to be multi-component, reaching beyond the PE class was also recognized. Results of the RCT showed a significant interaction effect between the Y-PATH intervention and time (p=0.025), with children in the Y-PATH schools recording an increase (10%) in minutes of accelerometer measured moderate-to-vigorous PA (MVPA) over the one year period, while children in the control school recorded a decrease over the same period.

Conclusion: In order to develop effective interventions researchers need to first understand the context and environment in which they are hoping to intervene, and the cohort they hope to target. Y-PATH is one example of how such a strategy can be effective, though future research must look to establishing the benefits of the intervention more longitudinally.

Awards:

Purpose: To assess the feasibility of implementing the GoActive intervention to whole school year groups, to test recruitment and measurement procedures, to determine preliminary effectiveness to increase moderate-to-vigorous physical activity (MVPA) and to inform power calculations to establish programme effectiveness.

Methods: Pilot cluster randomised controlled trial with 2 intervention and 1 control school(s); participants were 460 adolescents (46.6% female; 13.2(0.4) years-old). The 8-week intervention supported by Self-determination Theory and Social Cognitive Theory involved: Tutor groups choosing 2 weekly activities with participation encouraged by mentors (older adolescents) and in-class peer-leaders. Students gain points for trying activities; points are entered into an intra-mural competition. Outcomes were assessed at baseline and follow-up (week 8) and included: (primary outcome) ActiGraph-assessed MVPA; adolescent-reported activity type, peer-support, shyness, sociability. Quantitative (questionnaire) and qualitative (focus groups) process evaluation addressed enjoyment, confidence, participation and suggested improvements. ANCOVA was used to assess preliminary effectiveness as change adjusted for baseline.

Results: All Year 9 students in both intervention schools were exposed to the GoActive intervention; 77% of invited students were measured. Results indicate potential effectiveness (adjusted mean difference MVPA (mins (SE) p-value)) 5.1 (2.1) p=0.014) and suggest the need to recruit 16 schools (2400 adolescents) for a full trial. Compared to control, intervention students reported greater peer support 0.5 (0.2) p=0.03, but no difference in shyness or sociability; participation in activity types approached significance (intervention group 2.3 (1.3) p=0.07 more activity types). 71% boys and 74% girls found GoActive ‘fun'; 38% boys and 32% girls said it increased confidence and 64% boys and 59% girls said they would continue with an activity they tried during GoActive. Focus groups revealed occasional sex-imbalance in activity choices, and with that differential motivation to participate. Suggested programme changes included increased emphasis on mentorship, more initial training (mentors and teachers) and improved points recording systems.

Conclusions: Results provide an indication of the potential effectiveness of GoActive to increase MVPA in large groups of adolescents and support the need to formally establish effectiveness and cost-effectiveness. Process evaluation data was used to refine GoActive prior to a full trial, currently underway.
