Testosterone (T) is thought to help facilitate trade-offs between mating and parenting in humans. Across diverse cultural settings married men and fathers have lower T than other men and couples' sexual activity often declines during the first years of marriage and after having children. It is unknown whether these behavioral and hormonal changes are related. Here we use longitudinal data from ...

BACKGROUND being unmarried is associated with worse health and increased mortality risk. Telomere length has emerged as a marker for biological ageing but it is unclear how telomere length relates to marital status. OBJECTIVE to examine the relationship between telomere length and marital status in a sample of middle-aged adults. DESIGN AND SUBJECTS cross-sectional analysis among 321 adults...

OBJECTIVE This study investigated the impact of marital status on cancer-caused specific mortality among acute myeloid leukemia (AML) patients in the United States. METHODS We used the Surveillance, Epidemiology and End Results program to identify 50,825 patients who had their clinical and follow-up information available and were diagnosed for AML between the years 1988 and 2015. The univaria...

BACKGROUND There has been a rapid spread of non-marital childbearing in the Czech Republic during the last two decades. At the same time, the low birth weight rates of children born to married and unmarried mothers have converged. OBJECTIVE The goal is to explain the diminishing gap in low birth weight. Two explanations are assessed: the changing selection of unmarried mothers from disadvantage...

despite the challenges noticed in the meaning and concept of pederasty (lawāṭ), different viewpoints have always existed among the jurists concerning the punishment of the pederast, to the extent that some jurists have decreed death penalty equally for both the married and unmarried pederast. in contrast, some others have reconciled among the related traditions in this respect and considered th...

BACKGROUND Interpregnancy interval (IPI), marital status, and neighborhood are independently associated with birth outcomes. The joint contribution of these exposures has not been evaluated. We tested for effect modification between IPI and marriage, controlling for neighborhood. METHODS We analyzed a cohort of 98,330 live births in Montréal, Canada from 1997-2001 to assess IPI and marital st...

This study evaluated the association between marital status and colon cancer survival in SEER cancer registrants to determine if the survival benefit of married patients is due to earlier stage at diagnosis. The adjusted analysis that included stage at diagnosis showed 23% higher risk of death in single patients compared to married patients, which decreased from 28% in the unadjusted analysis. ...

Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 1,254), the authors investigated whether marriage can foster desistance from delinquency and violence by moderating genetic effects. In contrast to existing gene-environment research that typically focuses on one or a few genetic polymorphisms, they extended a recently developed mixed linear model to consider the...

Adolescent childbearing has received decreasing attention from academics and policymakers in recent years, which may in part reflect the decline in its incidence. Another reason may be its uncoupling from nonmarital childbearing. Adolescent childbearing became problematized only when it began occurring predominantly outside marriage. In recent decades, there have been historic rises in the rate...
