Background: Previous research has documented bidirectional associations between age at childbirth and socioeconomic status (SES) among mothers. Built on the Marginalization-related Diminished Returns (MDRs) theory, this study compares the association between maternal age at childbirth and income between non-Hispanic Blacks and non-Hispanic Whites. Methods: We used the data of the Fragile Families and Child Well-being Study (FFCWS), a longitudinal study from 1998 to 2016 in the United States (US). This study included 2922 women who were non-Hispanic White (n=776) or non-Hispanic Black (n=2146). Maternal age at childbirth was the independent variable, and income was the dependent variable. Educational attainment, marital status, delivery characteristics, car ownership, and welfare dependence were the covariates. For data analysis, linear regressions were applied. Results: Higher maternal age at childbirth was associated with higher income (adjusted b=0.30). We found a significant interaction between maternal age at childbirth and race on income, suggesting that the positive association between mothers’ age at childbirth and income was weaker for non-Hispanic Blacks than non-Hispanic Whites (b=-1.14, 95% CI=-1.50, -0.77). Conclusion: Postponing childbirth may have a smaller economic return for non-Hispanic Black women, which is in line with Marginalization-related Diminished Returns theory. Diminished returns of postponing reproduction may be a result of social stratification and structural inequalities that separate the lived experience of Blacks and Whites in the United States.

Objectives: This study compared 15 countries for multiplicative effects of gender by education and by income on self-rated health of individuals with chronic medical conditions.
Methods: We analyzed data from the Research on Early Life and Aging Trends and Effects (RELATE) Study. Participants were sampled from 15 countries including Argentina, Barbados, Brazil, Chile, Cuba, Costa Rica, China, India, Ghana, Russia, Puerto Rico, South Africa, Mexico, Uruguay, and the United States. The analytical sample was limited to individuals with at least one chronic medical condition. The main outcome of interest was self-rated health (SRH). Country-specific logistic regressions were used for data analysis. We ran separate models with gender × education and gender × income interactions.
Results: In Ghana, Uruguay, and India, gender moderated the effects of socioeconomic status (SES) on SRH. In Ghana and Uruguay, education and in Mexico and India, income had a stronger effect on SRH for women than men.
Conclusions: Countries vary in gender differences in vulnerability to SES indicators on SRH of patients with chronic medical conditions. Women are more vulnerable than men to the effect of low SES on SRH in Ghana, Uruguay, Mexico, and India.
