RESUMO
Background: Substantive literature has assessed the impact of starting school at younger ages relative to peers on health in high-income countries (HICs), but there is little evidence from low- and middle-income countries (LMICs). Conclusions drawn from HICs may not apply to different education contexts and health threats. This study maps the empirical evidence on the effect of school-entry age on health in LMICs and identifies directions for future research. Methods: We conducted a scoping review between August and September 2022 by systematically searching the health sciences, education, economics, psychology, and general sciences literature and included quantitative and qualitative studies. The exposure of interest was relative age for grade defined as starting or progressing through school at a younger or older age compared to peers who are in the same grade. We extracted key characteristics of included studies and summarized their findings. We categorized results into broad health domains which emerged a posteriori from our analyses of included studies, including neurodevelopment and mental health, sexual and reproductive health, non-communicable diseases, and nutrition. Findings: We identified 8 studies from middle-income countries published between 2017 and 2022. Among those studies, we identified 3 quasi-experimental studies using data from Brazil, Mexico, and Vietnam, and 5 observational studies primarily from Türkiye. Children starting school earlier had an increased risk of being diagnosed with attention deficit hyperactivity disorder, earlier sexual debut and cohabitation, adolescent pregnancy, adolescent marriage, and engaged more frequently in risky behavior compared to children who started school later. Pregnant women who started school younger also had fewer prenatal care visits and experienced more pregnancy complications. Although most studies identified negative health consequences from starting school earlier, the evidence for nutritional outcomes, such as overweight and stunting, was mixed. No studies were identified from low-income countries. Conclusions: Little is known about the health consequences of school-entry age in low-resource settings. Additional research is needed to investigate the impact of relative age for grade, whether and how these effects persist into adulthood, and to inform strategies that can offset potential disadvantages stemming from school-entry cut-off dates.
RESUMO
OBJECTIVES: Although multi-component policy interventions can be important tools to increase access to contraception, we know little about how they may change contraceptive use among postpartum women. We estimate the association of the Delaware Contraceptive Access Now (DelCAN) initiative with use of postpartum Long-Acting Reversible Contraception (LARC). DelCAN included Medicaid payment reform for immediate postpartum LARC use, provider training and technical assistance in LARC provision, and a public awareness campaign. METHODS: We used a difference-in-differences design and data from the 2012 to 2017 pregnancy risk assessment monitoring system to compare changes in postpartum LARC use in Delaware versus 15 comparison states, and differences in such changes by women's Medicaid enrollment. RESULTS: Relative to the comparison states, postpartum LARC use in Delaware increased by 5.26 percentage points (95% CI 2.90-7.61, P < 0.001) during the 2015-2017 DelCAN implementation period. This increase was the largest among Medicaid-covered women, and grew over the first three implementation years. By the third year of the DelCAN initiative (2017), the relative increase in postpartum LARC use for Medicaid women exceeded that for non-Medicaid women by 7.24 percentage points (95% CI 0.12-14.37, P = 0.046). CONCLUSIONS FOR PRACTICE: The DelCAN initiative was associated with increased LARC use among postpartum women in Delaware. During the first 3 years of the initiative, LARC use increased progressively and to a greater extent among Medicaid-enrolled women. Comprehensive initiatives that combine Medicaid payment reforms, provider training, free contraceptive services, and public awareness efforts may reduce unmet demand for highly effective contraceptives in the postpartum months.

Although the detrimental effects of the opioid epidemic on health and wellbeing have been well documented, we know little about how it has affected the family contexts in which children live. Using data from the 2000 Census, the 2005-2018 American Community Survey (ACS) and restricted Vital Statistics, we assess how the opioid epidemic, as measured by a rise in the opioid overdose death rate, affected the rates of children living in different family arrangements: two married parents, two cohabiting parents, single mother, single father, or another configuration. According to local fixed-effects models, a higher opioid overdose death rate is associated with fewer children living with two married parents and an increase in children living in family structures that tend to be less stable, such as those led by cohabiting parents or a single father. These changes in family arrangements have potential long-term implications for the wellbeing of future generations.
RESUMO
The United States has experienced a dramatic rise in opioid addiction and opioid overdose deaths in recent years. We investigate the effect of the opioid epidemic at the local level on nonmarital fertility using aggregate- and individual-level analyses. Opioid overdose death rates and prescriptions per capita are used as indicators of the intensity of the opioid epidemic. We estimate area fixed-effects models to test the effect of the opioid epidemic on nonmarital birth rates obtained from vital statistics for 2000-2016. We find an increase in nonmarital birth rates in communities that experienced a rise in opioid overdose deaths and higher prescription rates. Our analyses also show that the local effect of the opioid epidemic is not driven by a reduction in marriage rates and that marital birth rates are unaffected. Individual-level data from the ACS 2008-2016 are then used to further assess the potential causal mechanisms and to test heterogeneous effects by education and race/ethnicity. Our findings suggest that the opioid epidemic increased nonmarital birth rates through social disruptions primarily affecting unmarried women but not through changes in their economic condition.

CONTEXT: Little is known about whether adolescents' risk-taking in areas other than sex is associated with the effectiveness of their contraceptive method use, or whether any such associations vary by race and ethnicity. METHODS: Data from the 2011, 2013 and 2015 National Youth Risk Behavior Surveys were used to examine nonsexual risk behaviors and contraceptive method choice among 5,971 sexually active females aged 13-18. Risk-taking profiles for White, Black and Hispanic adolescents were identified using latent class analysis. Multinomial logistic regression was used to estimate the associations between these risk profiles and use of less- or more-effective contraceptive methods at last sexual intercourse. RESULTS: Three distinct risk-taking profiles were identified for White and Hispanic adolescents and two for Black adolescents. Compared with their counterparts in the low-risk "abstainer" group, White adolescents in the "high substance use and violence" group were less likely to use condoms alone (relative risk, 0.4) or a prescription contraceptive paired with condoms (0.3) rather than no contraceptive at all, and more likely to use withdrawal or no method rather than condoms alone (2.4 each). However, higher risk-taking among Whites was positively associated with using prescription contraceptives rather than condoms (1.9). Among Black and Hispanic females, lower risk-taking was associated only with more condom use. CONCLUSIONS: Future studies should examine whether interventions designed to reduce adolescent risk-taking improve the effectiveness of contraceptive use, particularly among White females. However, efforts to increase Black and Hispanic adolescents' use of more-effective contraceptives should target barriers other than risk-proneness.

A focus of research on short interpregnancy intervals (IPI) has been on young disadvantaged women whose births are likely to be unintended. Later initiation of family formation in the United States and other high-income countries points to the need to also consider a woman's attributes indicative of readiness for purposefully accelerated family formation achieved through short IPIs. We test for whether factors indicating "reproductive readiness"-including being married, being older, and having just had a first birth or a birth later than desired-predict a woman's non-use of contraception in the postpartum months. We also test for whether this contraceptive non-use results explicitly from wanting to become pregnant again. The data come from the 2012-2015 Pregnancy Risk Assessment Monitoring System, representing women who recently gave birth in any of 35 U.S. states and New York City (N = 120,111). We find that these reproductive-readiness factors are highly predictive of women's postpartum non-use of contraception because of a stated desire to become pregnant and are moderately predictive of contraceptive non-use without an explicit pregnancy intention. We conclude that planning for, or ambivalently risking, a short IPI is a frequent family-formation strategy for women whose family formation has been delayed. This is likely to become increasingly common as family formation in the United States is initiated later in the reproductive life course.

Research has documented a negative association between women's educational attainment and early sexual intercourse, union formation, and pregnancy. However, the implications that school progression relative to age may have for the timing and order of such transitions are poorly understood. In this article, I argue that educational attainment has different implications depending on a student's progression through school grades relative to her age. Using month of birth and age-at-school-entry policies to estimate the effect of advanced school progression by age, I show that it accelerates the occurrence of family formation and sexual onset among teenage women in Mexico. Focusing on girls aged 15-17 interviewed by a national survey, I find that those who progress through school ahead of their birth cohort have a higher probability of having had sex, been pregnant, and cohabited by the time of interview. I argue that this pattern of behaviors is explained by experiences that lead them to accelerate their transition to adulthood compared with same-age students with fewer completed school grades, such as exposure to relatively older peers in school and completing academic milestones earlier in life. Among girls who got pregnant, those with an advanced school progression by age are more likely to engage in drug use, alcohol consumption, and smoking before conception; more likely to have pregnancy-related health complications; and less likely to attend prenatal care visits. Thus, an advanced school progression by age has substantial implications for the health and well-being of young women, with potential intergenerational consequences.

The "Millennial" generation grew up in a period of changing gender roles, when labor force participation of mothers of young children was rapidly increasing. Past research has found that daughters of employed mothers are more likely to defy traditional gender scripts by seeking employment and authority positions. Building on this literature, I assess whether exposure to a full-time employed mother has an impact on Millennial women's participation in political organizations. I use prospective data on childhood context from the Panel Study of Income Dynamics, and apply propensity score weighting and a matching technique based on covariates. Evidence suggests that exposure to a full-time employed mother increases participation in political organizations for low-SES daughters. According to sensitivity tests, these findings are reasonably robust to unobserved confounders. In contrast, exposure to a full-time employed mother does not have a significant effect on the participation of sons or high-SES daughters.
