The effect of In-School Clinics on teen pregnancy & STI
ratesThe original PATHS Equity for Children project evaluating the effectiveness of in-school clinics on teen pregnancy & STI rates was reported on at CPHA in 2013. Subsequently, we posited two additional research questions:
1. What is the relationship between teen pregnancy or STIs and status of school enrollment, and 2. How is socioeconomic status related to enrollment status and outcomes (teen pregnancy & STIs)?

Study PremiseIn-school clinics provide services for youth in
school, including testing for STIs and advice regarding, or provision of contraception.
When we looked at the effectiveness of in-school clinics, we identified in the population three groups of adolescents aged 14 to 19 years of age (2003-2010):(1) Adolescents attending schools without clinics (2) Adolescents attending schools with clinics(3) Adolescents who were not enrolled in school

Subsequently…We identified a significant number of
young women giving birth who were not enrolled in school, and therefore not receiving the benefits of in-school clinics.
We present here an analysis of• The relationship between teen pregnancy or
STIs and school enrollment, and • How socioeconomic status is related to school
enrollment status, STIs or teen pregnancy

Methods• Repository data held at MCHP was used to identify
all teen girls with a birth outcome or males/females with STI prior to completing high school
• School enrollment was identified at the start of every school year; occurrence of teen births / STIs was assigned to adolescents in one of three groups: 1) enrolled in a school without an in-school clinic 2) enrolled in a school with an in-school clinic 3) NOT enrolled in school
• NOTE: schools which have an in-school clinic were targeted for this intervention based on teen pregnancy rates

STEPS:(1)Database compilation (2003/04-
2010/11)(a)Outcome variables: teen pregnancy
& STIs(b)Explanatory variables: age, mother’s
age at first birth, SES (income quintile), geographic place of residence (MB: N/M/S & Wpg M/L/Avg), birth control method(s) offered, hours open (by school size), academic year

Pregnancy • 9,292 pregnancies (2003-2010) recorded for the
cohort • 55% (5,140 / 9,292) occurred in the non-enrolled
group• Age-adjusted pregnancy rates by enrollment
group were:• Non school clinic: 31.8 / 1000• School clinic: 42.8 / 1000• Not enrolled: 87.9 /100
• Rate for non-enrolled females was 2.1 times (p<.0001) higher than school clinic females and 2.8 times (p<.0001) higher than non school clinic females

Sexually Transmitted Infections (STIs)• 4,297 positive STI tests were reported (2003-
2010) or 12.1 per 1000 adolescents • 48% (2,047 / 4,297) occurred in the non-enrolled
group• Female rates (16.5/1000) were over twice as high
as male rates (7.8/1000)• Age-adjusted STI rates by sex and enrollment
group were:• Non school clinic: F 10.2 M 4.1 / 1000• School clinic: F 19.5 M 8.3 / 1000• Not enrolled: F 23.9 M 14.2 /1000
• Crude STI rates for non-enrolled males was 3.5 times (p<.0001) higher than non-school clinic males and 2.3 times (p<.0001) higher than non school clinic females

CONCLUSION• In-school clinics appear to have been
systematically assigned and supported in schools with higher needs
• Highest rates for pregnancies and STIs were observed among non-enrolled adolescents
• Implications? – We may be missing the mark: Program
planning & design should consider optimal strategies to engage out of school youth
