Risks and Challenges in Adolescence: Nutrition, Early Marriage and Early Pregnancy • Adolescent girls often enter pregnancy with reduced
nutritional stores – Competition for dietary energy and nutrients
• Physical immaturity of the mother – More immature = ↑ obstetric risk – ↑ maternal mortality – ↑ prematurity, LBW
• Higher incidence of poor child health care and child feeding behaviors – Varies by SES – Interference of pregnancy with schooling completion

Risks and Challenges: Education, Reproductive Health, Sexual Practices and Marriage • Disparities by residence, wealth quintiles, and sex in
young adolescents • In some instances, disparities become more
pronounced in older adolescents (education gap) • Some unexpected trends:
• Early marriage in Indonesia • Family planning in Indonesia and Zambia

Risks and Challenges in Adolescence: Nutritional • Girls at greater risk of suffering nutritional difficulties than boys,
with more severe consequences as it relates to childbearing and perpetuating the cycle of malnutrition – Underweight – Stunting – Micronutrient deficiencies (anemia especially) – Obesity

Risks and Challenges in Adolescence: Nutritional (cont) • Lifestyle and eating behaviors, and underlying psychosocial factors also
threaten adequate nutrition • Adolescent pregnancy imposes additional physiological and
nutritional stress, especially in stunted or underweight mothers

School and Education-Based Programming
• School feeding • Anemia control • Nutrition-friendly school initiatives • Other school-based adolescent-focused
programs – India’s Saloni Swasth Kishori Yojna, Uttar Pradesh – Zambia’s UN Girls Education Initiative

Social Safety Net Programing • Cash Transfers: conditional and unconditional
– Impact on HIV and education in Malawi – Unconditional
• Varying impact based on recipient (mother/father) and conditionality – Conditionality matters more than recipient in terms of
improved child health outcomes • Not a lot of evidence specific to adolescents, but a
promising avenue for addressing factors proximally associated with adolescent nutrition and with broader social benefits – Education, early marriage, sexual behaviors, STIs, and early
pregnancy • Microfinance interventions

Youth Development and Community-Based Approaches • Peer education • Adolescent and youth centers • Faith-based community approaches • Other community-based approaches
– Indonesia linking of marriage registries to target health messages and IFA supplementation
– Promotion of gender equality at the community level to address violence and SRH

Other Interventions/Programming
• Health Center-Based Programming – Youth-Friendly Health and Nutrition Services
• Policy-level interventions – National-level
• Incentives to delay early marriage (India and Bangladesh)
• Scholarships for secondary education or life-skills training
• HIV-specific legislation
– Policies by large donor institutions • USAID’s Youth in Development Policy

Summary and Key Points
• Adolescents face many health and nutritional risks – Injuries are the leading cause of death – Other risks and challenges include mental health, substance
abuse, sexual and reproductive health (HIV especially), education, violence and abuse
– Girls are more vulnerable nutritionally, as a result of the link with early pregnancy and its impact on education, maternal obstetric outcomes, and child outcomes.
• Various types of delivery platforms to reach
populations with health and nutrition services in LMIC exist, but their potential for reaching adolescents (girls especially) has yet to be unleashed
