Mutual compensation of the effects of religious and ethnic homogamy on reproduction
ConclusionsWe suggest that the interaction between ethnic homogamy, religious homogamy, and reproduction provides an interesting example for gene‐culture co‐evolution. (Source: American Journal of Human Biology)

Measuring arterial blood pressure in humans: Auscultatory and automatic measurement techniques for human biological field studies
Abstract
Human biologists have been examining arterial blood pressure since they began studying the effects of the environment and culture on the health of diverse populations. The Korotkoff auscultatory technique with a trained observer and aneroid sphygmomanometer is the method of choice for blood pressure measurement in many bioanthropological field contexts. Korotkoff sounds (the first and fifth phases) are the preferred determinants of systolic and diastolic pressure, even in infants, children, pregnant women, and the elderly. Training of observers, positioning of individuals, and selection of cuff size are all essent...

Resemblance in physical activity levels: The Portuguese sibling study on growth, fitness, lifestyle, and health
ConclusionsAge, physical fitness, and parental support were the best predictors of TPAI levels. A moderate level of resemblance in TPAI was observed in SS pairs, while lower resemblance was found for BS and BB pairs. These findings may be due to differences in the roles of shared genetic factors, familial, and environmental characteristics across different sibling types.

Child fosterage and sex ‐biased nutritional outcomes among Namibian pastoralists
ConclusionsSex plays a role in the nutritional impact of fosterage among Himba children. These differences could be related to differential child labor demands, investment patterns, and the divergent reasons girls and boys are placed into fosterage. Future studies should consider how fosterage can magnify existing biases, like sex, when studying its impact on child health. (Source: American Journal of Human Biology)

Child stunting is associated with weaker human capital among native Amazonians
ConclusionsThe results confirm adverse associations between child stunting and human capital skills. Predictors of growth recovery and faltering can affect human capital outcomes, even in a remote, economically self‐sufficient society. (Source: American Journal of Human Biology)

Amerindian ancestry and extended longevity in Nicoya, Costa Rica
Conclusions and ImplicationsTo our knowledge, this is the first time that ancestry is implicated as a likely determinant of extended longevity. Amerindian‐specific alleles may protect against early mortality. The identification of these protective alleles should be the focus of future studies. (Source: American Journal of Human Biology)

Use of iDXA spine scans to evaluate total and visceral abdominal fat
ConclusionsThis replication of the strong correlation between SFF and abdominal fat measures on the iDXA in a new population confirms the previous Prodigy model findings and improves generalizability. (Source: American Journal of Human Biology)

Antioxidant defense and oxidative damage vary widely among high ‐altitude residents
ConclusionsHigh‐altitude residence alone does not associate with high antioxidant defenses; residence length appears to be influential. The single‐generation upward migrant sample had the lowest defense and nearly the highest DNA damage. The two high‐altitude resident samples with millennia of residence had higher defenses than the two with multiple or single generations of residence. (Source: American Journal of Human Biology)

Pregnancy and immune stimulation: re ‐imagining the fetus as parasite to understand age‐related immune system changes in US women
ConclusionsThis research supports the hypothesis that maternal immune systems respond to prior pregnancies as they do to macro‐parasitic exposures, and may modify the expected linear declines of IgE levels in women that accompanies aging. These finding have implications for understanding the evolution of internal gestation in mammals. (Source: American Journal of Human Biology)

Fifty years of child height and weight in Japan and South Korea: Contrasting secular trend patterns analyzed by SITAR
Conclusions The secular height trend in these countries represents increased growth in the long bones during infancy, so it can be viewed as the inverse of stunting. There are striking country differences in growth pattern, but they are not easily explained by differences in national income, diet or lifestyle. (Source: American Journal of Human Biology)
