What Works for Adolescent Reproductive Health: Lessons from Experimental Evaluations of Programs and Interventions

This Child Trends fact sheet reviews evaluated programs that focus on adolescent reproductive health. Among the findings: Many different types of programs have been shown to positively affect reproductive health outcomes. Not only school- and community-based sex education programs, but also clinic-based programs, youth development programs, service-learning programs, early childhood programs, and programs for young mothers have been found to be effective. Comprehensive sex education can improve adolescent reproductive health. Of the 21 comprehensive sex education programs that have been experimentally evaluated, 11 had a significant positive impact on the behavior of the youth studied or important subgroups of the sample. No abstinence-only interventions have yet been shown to positively affect any behavioral outcomes. Six abstinence-only interventions have had their impacts on behavioral outcomes experimentally evaluated. None has had an impact on initiation of sexual intercourse, frequency of sexual activity, number of sexual partners, use of condoms, use of contraceptives, pregnancies, births, or STD contraction. None of these six abstinence-only interventions have been shown to negatively affect any behavioral outcomes, either. In particular, in spite of their exclusive focus on abstinence, none have served to significantly decrease condom or contraceptive use. The fact sheet includes a table that shows whether the evaluated programs were found to work, not proven to work, or had mixed findings

Reading, writing, and raisinets: are school finances contributing to children’s obesity?

The proportion of adolescents in the United States who are obese has nearly tripled over the last two decades. At the same time, schools, often citing financial pressures, have given students greater access to “junk” foods and soda pop, using proceeds from these sales to fund school programs. We examine whether schools under financial pressure are more likely to adopt potentially unhealthful food policies. Next, we examine whether students’ Body Mass Index (BMI) is higher in counties where a greater proportion of schools are predicted to allow these food policies. Because the financial pressure variables that predict school food policies are unlikely to affect BMI directly, this two step estimation strategy addresses the potential endogeneity of school food policies. ; We find that a 10 percentage point increase in the proportion of schools in a county that allow students access to junk food leads to about a one percent increase in students’ BMI, on average. However, this average effect is entirely driven by adolescents who have an overweight parent, for whom the effect of such food policies is much larger (2.2%). This suggests that those adolescents who have a genetic or family susceptibility to obesity are most affected by the school food environment. A rough calculation suggests that the increase in availability of junk foods in schools can account for about one-fifth of the increase in average BMI among adolescents over the last decade.Overweight children ; Education ; Junk food

Teen Births: Examining the Recent Increase

This research brief explores whether the data reflect a short-term blip or a true reversal in the decline of the U.S. teen birth rate. It also considers potential explanations for the uptick in teen births, and raises data and research gaps that must be filled to inform public and private prevention efforts. Among the findings: --Declines in teen contraceptive use may have played some role in the teen birth rate increase. Between 2003 and 2005, a slightly greater percentage of high school girls reported using no method of birth control the last time they had sex. --Recent declines in teen sexual activity have stalled. --Economic hardship and the rising cost of certain birth control methods may also have made contraception less affordable for some teens.--National data indicate a significant decline between 1995 and 2002 in the percentage of students who report having received formal contraceptive education.This brief is based on a paper by Kristin Anderson Moore, Ph.D., that resulted from a meeting of experts and researchers convened by the National Campaign to Prevent Teen and Unplanned Pregnancy

Women and the Phillips curve: do women’s and men’s labor market outcomes differentially affect real wage growth and inflation?

During the economic expansion of the 1990s, the United States enjoyed both low inflation rates and low levels of unemployment. Juhn, Murphy, and Topel (2002) point out that the low unemployment rates for men in the 1990s were accompanied by historically high rates of non-employment suggesting that the 1990s economy was not as strong as the unemployment rate might indicate. We include women in the analysis and examine whether the Phillips curve relationships between real compensation growth, changes in inflation, and labor market slackness are the same for men and women and whether measures of “non- employment” better capture underlying economic activity, as suggested by Juhn, Murphy, and Topel’s analysis. From 1965 to 2002 the increase in women’s labor force participation more than offsets the decline for men, and low unemployment rates in the 1990s were accompanied by historically low overall non- employment rates. We find that women’s measures of labor market slackness do as well as men’s in explaining real compensation growth and changes in inflation after 1983. We also find some evidence that non-employment rates are more closely related to changes in inflation than other measures of labor market slackness; however, we do not find the same for real compensation growth.Labor market ; Phillips curve ; Wages ; Inflation (Finance)

The ACS Survey of Galactic Globular Clusters. X. New Determinations of Centers for 65 Clusters

We present new measurements of the centers for 65 Milky Way globular clusters. Centers were determined by fitting ellipses to the density distribution within the inner 2\arcmin of the cluster center, and averaging the centers of these ellipses. The symmetry of clusters was also analyzed by comparing cumulative radial distributions on opposite sides of the cluster across a grid of trial centers. All of the determinations were done with stellar positions derived from a combination of two single-orbit ACS images of the core of the cluster in $F606W$ and $F814W$. We find that the ellipse-fitting method provides remarkable accuracy over a wide range of core sizes and density distributions, while the symmetry method is difficult to use on clusters with very large cores, or low density. The symmetry method requires a larger field, or a very sharply peaked density distribution.Comment: 17 pages, 8 figures, Accepted for publication in AJ, supplementary material will be available upon publicatio

Maternal employment and overweight children

This paper seeks to determine whether a causal relationship exists between maternal employment and childhood overweight. We use matched mother/child data from the National Longitudinal Survey of Youth and employ econometric techniques to control for observable and unobservable differences across individuals and families that may influence both children's weight and their mothers' work patterns. Our results indicate that a child is more likely to be overweight if his/her mother worked more hours per week over the child's life. Analyses by subgroups show that it is higher socioeconomic status mothers whose work intensity is particularly deleterious for their children's overweight status.Employment (Economic theory) ; Overweight children
