The cost of reproduction in women: Reproductive effort and oxidative stress in premenopausal and postmenopausal American women
ConclusionsWe found no evidence of a trade‐off between somatic maintenance as measured by 8‐OHdG and reproductive effort in women from this American population. On the contrary, higher gravidity and parity in premenopausal women was associated with lower damage to cellular DNA caused by oxidative stress. These results highlight the importance of population variation and environmental conditions when testing the occurrence of life‐history trade‐offs. (Source: American Journal of Human Biology)

Resting metabolic rate of Indian Junior Soccer players: Testing agreement between measured versus selected predictive equations
ConclusionsFFM explained variation in RMR across age and sex. The FFM‐based Soares et al. (, British Journal of Nutrition, 79) equation for girls and body weight‐based Wong et al. (, Singapore Medical Journal, 53) equation for boys are best suited for predicting RMR. (Source: American Journal of Human Biology)

Longitudinal patterns in BMI and percent total body fat from peak height velocity through emerging adulthood into young adulthood
ConclusionsDuring emerging adulthood, the prevalence of OWO increased. Being NW at PHV was not protective against being overweight in young adulthood. Emerging adulthood appears to be a potential critical period for fat accrual and warrants further attention. (Source: American Journal of Human Biology)

Secular change in adult stature of modern Greeks
ConclusionsOur findings are consistent with earlier studies based on a much smaller time span. The negative effect of the economic and nutritional deprivation on stature as a result of warfare is apparent in our sample, at least for males. Furthermore, the positive effect of economic growth on stature is prominent for the entire population in the postwar period. (Source: American Journal of Human Biology)

No sex difference in digit ratios (2D:4D) in the traditional Yali of Papua and its meaning for the previous hypotheses on the inter ‐populational variability in 2D:4D
ConclusionsWe discuss the results in light of various factors that putatively shape the differences in digit ratios. We conclude that the results of our study contribute to the existing evidence suggesting that digit ratio might not be universally sexually dimorphic in humans.

Separating the Bruce and Trivers ‐Willard effects in theory and in human data
ConclusionsAttempts to identify mechanisms by which reproductive suppression affects fetal loss and characteristics of human birth cohorts should consider the Bruce Effect as an alternative to the Trivers‐Willard Effect. (Source: American Journal of Human Biology)

Stress, sex, and plague: Patterns of developmental stress and survival in pre ‐ and post‐Black Death London
ConclusionsThese results might reflect variation between the sexes in sensitivity to stressors, the effects of nutrition on pubertal timing, disproportionate access to dietary resources for males in the aftermath of the Black Death, the disproportionate deaths of frail individuals during the epidemic, or some combination of these factors.

Relationships between the second to fourth digit ratio (2D:4D) and game ‐related statistics in semi‐professional female basketball players
ConclusionsThis study found evidence that 2D:4D was a correlate of performance in an open‐skill sport. Female players with lower digit ratios tended to perform better in several aspects of basketball, especially defensively, and were more likely to be starters, suggesting they are the best players on the team in their positions. These results probably reflect the organizational benefits of prenatal testosterone. (Source: American Journal of Human Biology)

Validation of multi ‐frequency bioelectrical impedance analysis versus dual‐energy X‐ray absorptiometry to measure body fat percentage in overweight/obeses Colombian adults
ConclusionsOur analysis showed a strong agreement between the two methods as reflected in the range of BF%. These results show that mBCA and DXA are comparable methods for measuring body composition with higher body fat percentages. However, due to broad limits of agreement, we can only recommend mBCA for groups of populations. (Source: American Journal of Human Biology)

Association of common genetic variants with human skin color variation in Indian populations
ConclusionsThese observations support the findings that rs1426654 and rs4775730 located in SLC24A5, and rs11070627 and rs12913316 located in MYEF2 and CTXN2 genes respectively, are major contributors toward skin pigmentation and would aid in further unraveling the genotype‐phenotype association in Indian populations. These findings can be utilized in forensic DNA applications for criminal investigations. (Source: American Journal of Human Biology)

Positive effects of refugee presence on host community nutritional status in Turkana County, Kenya
ConclusionsKakuma Refugee Camp is associated with better host community energetic status indicators, compared to other relevant, regional sites varying in development and resources. Based on global nutritional standards, observed differences likely represent meaningful disparities in overall health. We suggest that access to cereals via refugee trade networks and employment might mediate this relationship. However, perceptions of refugees as illegitimate interlopers maintain a high psychological burden. (Source: American Journal of Human Biology)
