Correlates of Sexual Behavior Across Fatherhood Status: Finding From the National Longitudinal Study of Adolescent to Adult Health (Add Health), 2016-2018

Amid national trends in postponed parenthood and more diverse family structures, the fatherhood identity may be important to men's sexual behaviors. This study examined factors associated with reports of consistent contraceptive use and multiple sexual partners across fatherhood status. Using public data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), Wave V (2016-2018), two sexual behaviors were examined among 1,163 men aged 32 to 42 years. Outcomes were two binary indicators: consistent contraceptive use with partner and having multiple (≥2) sexual partners in the past year. Fatherhood status was categorized as nonfather, resident father, and nonresident father. Demographic (e.g., race/ethnicity, education, income, and relationship type) and health-related (e.g., drinking, perceived stress, depressive symptoms, and insurance status) factors were considered. Logistic regression analysis produced odds ratios and 95% confidence intervals and were stratified by fatherhood categories. In the sample, 72% of men were resident fathers, 10% were nonresident fathers, and 18% were nonfathers; 28% reported consistent contraceptive use and 16% reported multiple sexual partners. For nonfathers, relationship type and race were associated with reporting multiple sexual partners. For resident fathers, relationship type was the crucial factor associated with consistent contraceptive use and reporting multiple sexual partners. In nonresident fathers, relationship type, education, and income were important factors to consistent contraceptive use and reporting multiple sexual partners. Key findings suggest that relationship type, income, and education are crucial factors to men's sexual behavior. Heterogeneous effects were observed across fatherhood status. This study adds to limited research on fatherhood and sexual behavior among men transitioning from young adulthood to middle age.

Union and Family Formation During Young Adulthood: Insights From the Add Health

Family formation patterns among US young adults are shifting, reflecting an accelerating retreat from marriage coupled with significant increases in cohabitation and nonmarital childbearing. Drawing on a selection of published longitudinal studies, this article reviews key contributions to the literature on these trends in union and family formation that have stemmed from research conducted using the National Longitudinal Study of Adolescent to Adult Health, or Add Health. Add Health is integral to deciphering the adolescent precursors to young adult union formation and childbearing, allowing researchers to gauge the roles of multiple social contexts such as family, schools, peers, and adolescent romance, with attention to variation across racial-ethnic groups and by socioeconomic status. In turn, researchers use Add Health to assess how young adult family formation behaviors are related to numerous indicators of health and well-being, ranging from mental and physical health to relationship quality and stability, interpersonal violence, and crime. With its sibling and couples samples, genetic data, and detailed partnership histories for both different- and same-sex relationships, Add Health is an invaluable data source for tracking the familial experiences (formation and dissolution) of a large cohort from adolescence into middle age.

How soon do single mothers have another child? A competing risk analysis of second premarital childbearing in sub-Saharan African countries

BACKGROUND

A considerable number of previous studies have examined the trends, correlates, and consequences of premarital childbearing among adolescents and young women in Africa. However, very little is known about whether and how soon single mothers have another premarital birth in sub-Saharan African countries. This study examines the timing of a second premarital birth among single mothers and assesses how it may differ across key socio-demographic variables.

METHODS

We pooled recent Demographic and Health Surveys from 25 sub-Saharan African countries to create a database of 57, 219 single mothers aged 15-49 years. Cumulative incidence graphs and Fine and Gray's competing risk models were used to delineate the timing of a second premarital birth and its socio-demographic correlates.

RESULTS

More than one-third of single mothers in 16 countries have had a second premarital birth in their reproductive life. We also observed that more than 15% of the single mothers in Angola, Benin, the Republic of Chad, Liberia, Namibia, Nigeria, Sierra Leone, and Uganda, have had another premarital birth three years after the first. The incidence of a second premarital birth was significantly lower among women with secondary or higher education, compared to women with less than secondary education (p < 0.05) in most countries. Residence in an urban area compared to rural, was also significantly associated with a low incidence of second premarital birth in 10 countries (p < 0.05).

CONCLUSIONS

Findings indicate a rapid progression to having a second premarital birth in some sub-Sahara African countries, particularly among socio-economically disadvantaged women. The findings suggest the need for tailored interventions for improving the quality of life of single mothers, to reduce the associated burden and consequences of having a premarital birth.
