Attention deficit/hyperactivity disorder (ADHD) symptoms and digit ratios in a college sample
Diagnosticians recognize three subtypes of attention deficit/hyperactivity disorder (ADHD) if there are developmentally inappropriate levels (six or more symptoms) of Hyperactive‐Impulsive behavior, or Inattentive behavior, or both (Combined), respectively. ADHD may partly reflect androgen dysfunction, and an arguable proxy for prenatal androgen exposure is the 2D:4D finger ratio set at least as early as week 9 in the fetus; this is lower in men …
Distribution of postpartum amenorrhea in rural Bangladeshi women
Previous studies of postpartum amenorrhea (PPA) demonstrated distinct subgroups of women with short and long durations of amenorrhea. This phenomenon was attributed to cases where breastfeeding is absent because of pregnancy loss or infant death, or confusion of postpartum bleeding with resumption of menses. We explored these ideas using data from an 11‐month prospective study in Bangladesh in which 858 women provided twice‐weekly interviews and …

Reproductive Measures, Fitness, and Migrating Mennonites
Given the same reproductive span, more children with shorter interbirth intervals and less parental attention per child should not do as well. There should be intermediate optima in family sizes, but only two studies have demonstrated optima. The goal here is to determine whether the relationship between fitness and fertility is linear and whether this relationship masks underlying variation in reproductive behaviors in a Mennonite congregation t…
Patterns for the initiation of breastfeeding in humans
Establishment of lactation has important biological and emotional health consequences for the newborn. Even so, substantial variation within a culture and among different cultures is seen in the onset of breastfeeding. Parametric mixture models are used to explore this variation and to uncover general human patterns for the initiation of breastfeeding. The model components reflect two hypothesized patterns of behavior. The first component is a “n…

Colostrum Feeding Behaviour and Initiation of Breast-Feeding in Rural Bangladesh
Human breast milk is primarily colostrum immediately following birth. Colostrum gradually changes to mature milk over the next several days. The role of colostrum in fighting infections and promoting growth and development of the newborn is widely acknowledged. This role is mediated by differences across cultures in the acceptability of colostrum and the prevalence of colostrum feeding. This study examined the prevalence of colostrum feeding and …

Aging, Voting, and Political Interest
Cross-sectional data on voter turnout and political interest from 28 American national surveys, and data from a cohort analysis of voter turnout, indicate a pronounced increase in political interest and participation from young adulthood to middle age. Voter turnout apparently remains almost constant from middle age to advanced maturity, and average political interest apparently increases. These findings are related both to theories of political …
