Background: Reproductive coercion (RC) is a type of abuse where a partner intentionally attempts to interfere with fertility through deception or violence, often by manipulating one's contraceptive use or reproductive decision-making. Cross-sectional studies on the magnitude of RC across sub-Saharan Africa have noted associations with contraceptive use. No studies have longitudinally examined RC experiences as related to future contraceptive dynamics, including discontinuation or forgoing use altogether.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

This paper critically examines the scientific and ethical underpinnings of gender-affirming care, particularly for minors. While major medical organizations endorse such interventions as medically necessary, the evidence supporting their long-term safety and efficacy remains limited. Research into hormonal, neuroanatomic, and genetic influences reveals a strong biological basis for gender identity, challenging social constructionist arguments.

China is currently facing a notable decline in fertility rates. This research introduces a novel perspective on the factors influencing fertility among women of reproductive age, representing the first attempt to examine the impact of peer grit on female fertility. Analyzing nationally representative panel data from China and leveraging plausibly exogenous variations in peer exposure across cohorts, we find that peer grit is associated with a reduction in fertility behavior and intentions.
