Assortative mating in phenotype in human marriages has been widely observed. Using genome-wide genotype data from the Framingham Heart study (FHS; number of married couples = 989) and Health Retirement Survey (HRS; number of married couples = 3,474), this study investigates genomic assortative mating in human marriages. Two types of genomic marital correlations are calculated. The first is a co...

Productivity, Wages, and Marriage: The Case of Major League Baseball Using a sample of professional baseball players from 1871–2007, this paper aims at analyzing a longstanding empirical observation that married men earn significantly more than their single counterparts holding all else equal (the “marriage premium”). Baseball is a unique case study because it has a long history of statistics c...

BACKGROUND Among the eight known human herpes viruses, Epstein- Barr virus (EBV) is considered to be sexually transmissible. This study was conducted to evaluate the seroepidemiology of this infection in married and unmarried Iranian couples. METHODS In this comparative observational and cross-sectional study, 160 men and women were divided into married and unmarried groups. Serum IgG and IgM...

INTRODUCTION The HIV prevalence rate in Ethiopia for married (or cohabiting) women is 3 times that found amongst women who have never been married. While marriage used to be seen as a protective factor against HIV, evidence suggests that this is no longer necessarily the case. This study analyses the trend and socio-demographic determinants of HIV awareness and safe sex negotiation among marrie...

A study on gestational diabetes mellitus (GDM) among 200 married women in Malappruam, Kerala, India, chose to exclude married women below the age of 18 from participation. Marriages before age 18 are not considered legally valid and persons below age 18 do not have the status of an adult. Parents are considered the legal guardians of married women under age 18, but because marriages are patrilo...

A divide exists between categories of men who have sex with men (MSM) in India based on their sex position, which has consequences for the design of novel HIV prevention interventions. We examine the interaction between sex position and other attributes on existing HIV risk including previous HIV testing, unprotected anal intercourse (UAI), and HIV serostatus among MSM recruited from drop-in ce...

Article history: Received 25 November 2010 Received in revised form 21 February 2011 Accepted 21 February 2011 Available online 17 March 2011 Childhood intelligence (age 11) and occupational social status at midlife (age 46 to 51) was associated with marital status and reproduction in a sample from the Aberdeen Children of the 1950s cohort study (N=9614). Male and female divorcees had lower chi...

Previous research finds that marriage is associated with better health and lower mortality, and one of the mechanisms underlying this association is health-related selection out of marriage. Using longitudinal survey data from 2,348 couples from the Fragile Families and Child Wellbeing Study, we examine whether certain health behaviors-smoking and binge drinking-are associated with risk of unio...

The tax regimes applied to couples in many countries including the US, France, and Germany imply either a marriage penalty or a marriage bonus. We study how they affect the decision to get married by considering two potential spouses who play a marriage proposal game. At the end of the game they may get married, live together without formal marriage, or split up. In this signaling game, proposi...

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 ...
