Surname‐Inferred andean ancestry is associated with child stature and limb lengths at high altitude in Peru, but not at sea level
ConclusionsGreater Andean ancestry is associated with shorter stature and limb measurements at high but not low altitude. Gene‐environment interactions between high altitude and Andean ancestry may exacerbate the trade‐off between chest dimensions and stature that was proposed previously, though we could not test this directly.

Breastfeeding over two years is associated with longer birth intervals, but not measures of growth or health, among children in Kilimanjaro, TZ
ConclusionsWe suggest that these relationships may support the recently rekindled birth spacing hypothesis, positing selection for longer interbirth intervals, rather than, or in addition to, more direct health benefits associated with breastfeeding for 2 or more years. Our results may indicate attenuating health benefits associated with longer breastfeeding. Am. J. Hum. Biol., 2015. © 2015 Wiley Periodicals, Inc. (Source: American Journal of Human Biology)

Relationship between maternal and newborn endothelial function and oxidative stress
ConclusionStudy findings suggest that under physiological conditions, enhanced endothelial function and/or oxidative stress in the mother may impact on normal fetal development. Future studies are recommended, employing larger sample sizes, a more extensive set of markers of oxidative stress, and comparisons of complicated versus normal pregnancies. Am. J. Hum.

Woman's body symmetry and oxidative stress in the first trimester of pregnancy
ConclusionThe level of OS is likely to be a substantial and important fitness trait, and FA may convey information on the level of OS in women. The result confirms that FA is an indicator of biological condition, as suggested by an evolutionary approach to morphological human traits perceived as attractive. Am. J. Hum.

Dehydroepiandrosterone and multiple measures of functional immunity in young adults
ConclusionsWhile interactions with other hormones did not significantly relate with immune function measures in this sample, DHEA and DHEA‐S did differentially impact multiple branches of the immune system. Generally characterized as immunosupportive in action, DHEA is shown to inhibit certain facets of innate and cell‐mediated immunity, suggesting a more complex role in regulating immunocompetence. Am.

Breast size and asymmetry during pregnancy in dependence of a fetus's sex
ConclusionPregnancy‐induced breast volume increase is a better cue of a fetus's sex than breast asymmetry or breast size per se, i.e., the traits that are supposed to indicate a woman's biological condition. Women with a larger increase in breast size during pregnancy are more likely to carry to term a more ecologically vulnerable male fetus. Am. J. Hum. Biol., 2015. © 2015 Wiley Periodicals, Inc.

Gross motor coordination and weight status of Portuguese children aged 6–14 years

Physical strength and dance attractiveness: Further evidence for an association in men, but not in women

Secular trends in body height and body mass in 19‐year‐old polish men based on six national surveys from 1965 to 2010
ConclusionsThe trend of body size and stature increase within the Polish population, although decelerating, remained positive and steady during the last 45 years. No significant impact of the past half‐century's socioeconomic crises was observed in these measures of growth. We concluded that during the economic crises some effective mechanism protecting the living conditions of the children and youth were operating within the population. Am. J. Hum.

Disposable collection kit for rapid and reliable collection of saliva
ConclusionsThe disposable saliva collection kit allows accurate and repeatable collection of fixed amounts of whole saliva and does not interfere with subsequent measurements of salivary cortisol.

5′ and 3′ β‐globin haplotypes in purepechas and Tarahumaras, two Mexican indigenous groups
ConclusionsThe 5′Hp analysis showed great variability in worldwide populations, including PUR and TAR, while 3′Hp frequencies were similar among indigenous Mexican and other populations with Asiatic origins. This suggests that 5′Hp exposes the microevolutionary process of each population and the 3′Hp establishes genetic relationships among populations. Am. J. Hum.

Time trends in BMI, body fatness, and adiposity rebound among boys from Kraków (Poland) from 1983 to 2010

Women who deliver twins are more likely to smoke and have high frequencies of specific SNPs: Results from a sample of African–American women who delivered preterm, low birth weight babies
ConclusionsWe provide a mechanistic explanation and preliminary evidence for previous reports that mothers of twins are more likely to have smoked, despite seemingly conflicting evidence for the fertility‐reducing effects of nicotine. Nicotine, as an aromatase inhibitor, inhibits estrogen synthesis and may allow for greater production of gonadotropins. While smoking may have deleterious effects on fertility across many genotypes, in women of specific genotypes it may raise their odds of producing twins. TP53 involvement suggests the necessity of future work examining relationships between women who bear multiples and can...

Digit ratio (2D:4D) does not correlate with daily 17β‐estradiol and progesterone concentrations in healthy women of reproductive age
ConclusionsThis study shows, for the first time in a large sample of women of reproductive age, that 2D:4D is not a predictor of adult women's sex hormone concentration. The lack of relationship may be because 2D:4D might be genetically determined and is not related to maternal nutritional environment during fetal development. These results support the hypothesis that, in contrast to the nutritional quality of the fetal environment, the fetal hormonal environment (reflected by 2D:4D) does not determine reproductive physiology in later life.

The first wave of the 1918 influenza pandemic among soldiers of the Canadian expeditionary force
ConclusionsThe CEF findings suggest that local, geographic heterogeneity characterized the first wave of the 1918 influenza pandemic in Canada and illustrate the ways in which well‐established, historical patterns of cross‐border social contact with the United States, coupled with the special conditions created by warfare, disproportionately funnelled influenza into particular regions. Identification of the mild first wave among soldiers in the CEF calls for more research on the civilian experience of both waves of influenza in Canada. Am. J. Hum.

The physiological cost of reproduction for rich and poor across 65 countries
ConclusionThese findings show how the level of economic resources can systematically and profoundly shape a physiological tradeoff in reproduction, and can help account for past contradictory findings. More broadly, these results illustrate how integrating economic and energetic resources in a common framework can help clarify the apparently disparate weight‐related outcomes of fertility in different countries.

Sex differences in children with severe health conditions: Causes of admission and mortality in a Pediatric Intensive Care Unit

Traces of forgotten historical events in mountain communities in Central Italy: A genetic insight
ConclusionsThe samples highlight an overall European genetic pattern both for mtDNA and Y chromosome. Notwithstanding this scenario, Y chromosome haplogroup Q, a common paternal lineage in Central/Western Asia but almost Europe‐wide absent, was found, suggesting that Central Italy could have hosted a settlement from Anatolia that might be supported by cultural, topographic and genetic evidence.
