Abstract:
Cardiovascular diseases (CVDs), which are disorders of the heart and blood vessels, are the world’s leading cause of death (WHO, 2016). The transition from infectious diseases to non-communicable diseases (NCDs), primarily CVDs, as the primary cause of mortality and morbidity worldwide— combined with the economic burden associated with heart-related diseases—prompted the World Health Organization (WHO) and its regional offices to identify CVDs’ risk factors (WHO, 2016). This paper examines these risk factors with a focus on the fetal environment and its interaction with adult body mass index (BMI), using longitudinal data from the Cebu Longitudinal Health and Nutrition Survey (CLHNS). Using a Cox proportional hazards model to estimate hazard ratios adjusted for age and risk factors in adulthood, such as cigarette smoking, the results suggest that there is a positive association between birth weight and heart disease. In addition, when birth weight is interacted with BMI, raised blood pressure is found to be higher among those who were bigger infants at birth and grew to be lighter adults, suggesting centile crossing. Probit models are also used for sensitivity analysis, and the results are consistent with those of the hazards model. Other factors such as adult obesity and a smoking habit are also positively associated with hypertension and CVD.

Abstract:
Risky health behaviors such as illicit drug use, smoking, overconsumption of alcohol, violence, and early sexual activity have contemporaneous and intertemporal adverse health and economic outcomes. The health-related and economic costs to individuals and to society overall are particularly pronounced when adolescents are the ones engaging in one or more of such behaviors. This paper uses longitudinal data from the Philippines (from the Cebu Longitudinal Health and Nutrition Survey) to examine the long-term impact of adolescents’ risky behaviors in 2002 (related to sex, tobacco, alcohol, and violence, but not drugs) on their economic outcomes in 2009 (related to participation in the labor force, educational attainment, and family formation). The results reveal that risky behaviors are most likely to affect educational outcomes. Teenagers who smoked at least one cigarette a day were 21% less likely to be in college several years later, and this difference was 17% for those who had an early sexual initiation, and 7% for those who consumed alcohol at least once a week. Labor outcomes were also adversely affected.
