Social Network and Weight Misperception among Adolescents

It is recognized that public health intervention targeted toward changing lifestyle behaviors to reduce overweight status is a considerable challenge. It is important that individuals recognize their overweight status as a health risk in order for an effective change in lifestyle behaviors to occur, and growing evidence suggests that actual weight and perception of weight status often do not match, especially among adolescents. In this article, we explore the extent to which exposure to heavier peers and parents affects misperception of their own weight status by adolescents. Using data from a nationally representative sample of adolescents, we estimated instrumental variable models with school‐level fixed effects to account for bidirectionality of peer influence and environmental confounders. Our results indicate that individuals who live in an environment that exposes them to overweight/obese parents and heavier peers tend to misperceive their weight status and think of themselves to be of lower weight than they actually are. Our analysis also revealed differential effects by gender and type of peers.     

Economic determinants of fertility in Belarus

This study examines the determinants of births in Belarus in 1996–2007 by using detailed micro‐data from the Belarusian Household Budget Surveys (BHBS). The existing literature offers several explanations of the recent trends in fertility in Belarus and in other former Soviet Union countries. It is often argued that the collapse of the Soviet Union and the concomitant economic instability reduced fertility in the 1990s, while economic growth and stabilization were responsible for its recovery since 2005. We evaluate these and other hypotheses by looking at the determinants of the first, second and third births, separately for women aged below 30 years of age and above 30 years of age. We provide evidence on the presence and the relative importance of the economic determinants, including income and wages, economic uncertainty, maternity and child‐care benefits. Our findings could inform demographic policies in Belarus and in other transitional countries.
