    ABSTRACT: Objectives: The aims of this study are to characterize the frequency of the derived allele at rs387907171 in populations from the islands of New Britain and Bougainville in Northern Island Melanesia, to confirm its association with lighter hair color, and to refine hypotheses regarding its evolutionary history. Methods: rs387907171 was genotyped in 93 individuals from New Britain and 101 from Bougainville for whom quantitative assessments of skin and hair pigmentation were available. Combining these with existing data from other Melanesian islands we tested for differences in allele frequencies between islands and for associations with skin and hair pigmentation using ANOVA, including sex, age, and island affiliations as covariates. Results: The derived allele at rs387907171 was observed in a single copy in the New Britain and Bougainville populations genotyped here. Its frequency differs significantly among islands in the region (χ(2) = 206.5, df = 3, P < 0.001). rs387907171 remains significantly, although weakly, associated with lighter hair pigmentation (F = 10.28, R(2) = 0.0125, P = 0.0014). This association increases when sex and age (F = 20.68, R(2) = 0.074, P < 7.92 × 10(-13) ) are included as covariates. Conclusions: The rs387907171 SNP exhibits strong allele frequency differences among islands in Northern Island Melanesia. Its absence from Bougainville, as well as the weak association with decreased hair color, indicates that additional alleles contribute to the blondism phenotype. Its geographic distribution suggests that a Lapita-mediated model for the dispersal of the derived allele at rs387907171 remains a viable evolutionary scenario. Am. J. Hum.

    ABSTRACT: Objectives: Profiles of plasma free amino acids (PFAAs) have been utilized as biomarkers to detect various diseases. However, few studies have investigated whether ethnicity or specific subpopulations within East Asia influence PFAA concentrations. Methods: A total of 95 healthy volunteers living in Japan, including 31 Japanese individuals, 36 Korean individuals and 28 Chinese individuals, were enrolled. Participants' PFAA levels were measured by high-performance liquid chromatography mass spectrometry, and the effects of factors such as sex, age, body mass index (BMI) and subpopulation on PFAA profiles were analyzed. Results: With the exception of glutamine and α-aminobutyric acid, there were no significant differences among the three examined subpopulations with respect to either the means or the distributions of PFAA concentrations. A multiple regression analysis revealed that most of the PFAA concentrations were significantly related to sex. Ornithine concentrations, glutamate concentrations, and glutamine and α-aminobutyric acid concentrations were significantly associated with age, BMI, and Chinese subpopulation, respectively. Conclusion: The study results indicate that the contributions of subpopulation within East Asia to PFAA profiles are small, particularly relative to the contributions provided by sex. Am. J. Hum.

    ABSTRACT: Objectives: Although many theories of human facial attractiveness propose positive correlations between facial attractiveness and measures of actual health, evidence for such correlations is somewhat mixed. Here we sought to replicate a recent study reporting that women's facial attractiveness is independently related to both their adiposity and cortisol. Methods: Ninety-six women provided saliva samples, which were analyzed for cortisol level, and their height and weight, which were used to calculate their body mass index (BMI). A digital face image of each woman was also taken under standardized photographic conditions and rated for attractiveness. Results: There was a significant negative correlation between women's facial attractiveness and BMI. By contrast, salivary cortisol and facial attractiveness were not significantly correlated. Conclusions: Our results suggest that the types of health information reflected in women's faces include qualities that are indexed by BMI but do not necessarily include qualities that are indexed by cortisol.

    ABSTRACT: Objectives: In high-income populations, evidence suggests that socioeconomic disadvantage early in life is correlated with reproductive strategy. Children growing up in unfavorable rearing environments tend to experience earlier sexual maturity and first births. Earlier first births may be associated with higher fertility, but links between socioeconomic disadvantage and larger family size have rarely been tested. The pathways through which early disadvantage influences reproduction are unknown. We test whether physiological factors link childhood adversity to age at first birth and total children. Methods: Using data from the Newcastle Thousand Families Study, a 1947 British birth cohort, we developed path models to identify possible physiological traits linking childhood socioeconomic status, and poor housing standards, to two reproductive outcomes: age at first birth and total children. We explored birth weight, weight gain after birth, childhood illnesses, body mass index at age 9, age at menarche, and adult height as possible mediators. Results: We found direct, negative effects of socioeconomic status (SES) and housing on age at first birth, and of housing on fertility. Although we found links between childhood disadvantage and menarche and height, neither of these were significantly correlated with either reproductive outcome. Age at first birth completely mediates the relationship between childhood adversity and total fertility, which we believe has not been empirically demonstrated before. Conclusions: While there are some links between childhood adversity and child health, we find little evidence that physiological pathways, such as child health and growth, link early childhood adversity to reproductive outcomes in this relatively well-nourished population.

    ABSTRACT: Objectives: Few studies have reported on the association between changes in serum low-density lipoprotein cholesterol (LDL-C) and height increase. We investigated the association between LDL-C change and height increase during puberty in a 3-year follow-up study in Fukuroi City, Japan. Methods: The source population was all fifth grade 2,515 students enrolled in any public school in Fukuroi, Japan in 2008, 2009, and 2010. The follow-up survey was conducted in eighth grade students in 2011, 2012, and 2013. In total, 2,225 adolescents were followed. To evaluate the relationships between height increases and changes in LDL-C, a regression analysis was conducted after stratification by tertiles of weight change (LW: lowest group, MW: middle group, and HW: highest group). Results: In each weight change tertile, serum LDL-C significantly decreased from the lowest to highest tertiles of height change (LW: regression coefficient (B) = -0.12, MW: B = -0.07, HW: B = -0.08 in males; MW: B = -0.17, HW: B = -0.14 in females). The association between height increases and LDL-C was significantly stronger than that between weight increases and LDL-C (male: B = -0.609 and 95% CI -0.836 to -0.382 in height, B = 0.008 and 95% CI -0.193 to 0.209 in weight; female: B = -0.963 and 95% CI -1.301 to -0.624 in height, B = 0.366 and 95% CI 0.058-0.675 in weight). Conclusions: Serum LDL-C decreased with increasing height, independent of increases in weight. The association between LDL-C and height is stronger than that between LDL-C and weight. Am. J. Hum.

    ABSTRACT: Objectives: The purpose of this study was to determine whether the month of birth influences the maturation rate of Polish females from two birth cohorts, namely 1982-1984 and 1992-1994. It was also verified whether socioeconomic status (SES) is capable of altering the above relationship. Methods: The research material consisted of data collected in two cross-sectional surveys. The first cohort involved 1,008 female secondary-school students, the second, 671 female university students. Information on subjects' date of birth, SES, and the age at menarche was obtained from a questionnaire. The subjects were divided into four groups, according to the month of birth: born in spring (III-V), born in summer (VI-VIII), born in autumn (IX-XI), and born in winter (XII-II). Next, the subjects were divided into two groups: born in summer months (VI-VIII) and born in the other months (IX-V). Results: In the first cohort, subjects born in the summer reach menarche significantly earlier than subjects born in other seasons. The same tendency was noticeable in subjects born in the years 1992-1994; however, the differences were not statistically significant. In both cohorts, girls born in summer months had their first menstruation at a younger age than girls born in other months. The difference in age at menarche between season/months was also seen after dividing the data into uniform groups in terms of SES. Conclusion: The present data suggest that the season of birth influences sexual maturation rate in women. Am. J. Hum. Biol., 2015. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: Objectives Geographic variation in human nasal form has often been interpreted as a climatic adaptation, owing to the nasal air-conditioning function. The aim of this study was to further address morphofunctional issues of the nasal cavity, using three human groups from subarctic, temperate, and subtropical regions of the Japanese Archipelago: prehistoric Okhotsk, early-modern Honshu and Okinawa groups.Methods Using three-dimensional coordinates of craniometric landmarks surrounding the nasal cavity, we compared linear measurements regarding nasal cavity form among the three groups and also conducted 3D geometric morphometrics.ResultsBoth linear measurements and morphometric analyses corroborate the previously reported covariation pattern of nasal cavity shape with climate, where humans from a cold/dry climate tend to possess a relatively tall, narrow, and deep nasal cavity compared with those from a warm/humid environment. The northern Okhotsk group had overall larger cranial airways, which may be attributable to their large facial skeleton. However, the ratio of nasal/bimaxillary breadth was significantly lower in the Okhotsk group, indicating that maxillary size does not necessarily constrain the nasal breadth. In addition, despite the presence of obvious geographic clines in anterior nasal shape, posterior choanal shape lacked the north-south geographic cline. This suggests a certain level of morphofunctional independence between the anterior and posterior nasal openings.Conclusions The observed geographic variations must, however, be partly considered as a reflection of different ancestral traits and population histories of the three groups. Nevertheless, the results indicate that intergroup variations in nasal cavity morphology can be largely explained by climatic conditions. Am. J. Hum. Biol., 2015. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: Objectives To reveal the conditions that could facilitate childbirth in modern humans, it is necessary to analyze not only cross-sectional surveys but also panel data that track the same person for a long period. In this study, we analyzed factors that would influence the probability of childbirth.Methods We analyzed Japanese panel data with a Cox proportional hazard model. Subjects of our analysis were married women and their childbirth records from 2004 to 2009.ResultsContrary to the predictions based on the theory of behavioral ecology, we found no positive relationship between good parental conditions for childcare, such as high income, increase in income, or coresidence with parents (i.e., grandparents of children), and the occurrence of childbirth. We found that the number of existing children had a significant impact on the probability of childbirth. The likelihood of further childbirth by couples with one child was nearly equal to that of childless ones. However, the corresponding likelihood of couples with two children was about five times lower than that of childless ones.Conclusions The total fertility rates in modern developed societies are quite low and couples prefer having two children. This trend is known as the two-child norm, but it is a paradoxical phenomenon in terms of fitness maximization. Our result provided new quantitative evidence of this norm. This study revealed that the number of existing children being less than two was one of the factors associated with further childbearing in our Japanese sample. Am. J. Hum.

    ABSTRACT: Objectives The goal of this study is to compare both dental and skeletal stress indicators of the Classic and Postclassic coastal and inland sites of the State of Quintana Roo, Mexico. The hypothesis is that coastal populations will show osteo and dental pathologies characteristic of a primarily marine food source combined with a diet of horticultural resources. This kind of alimentation provides people with less environmental stress and therefore a better health status. However, over time, in the Postclassic period, the health conditions deteriorated among both coastal and inland inhabitants, according to the hierarchization of the society, militarization, and commercial activities of all the coastal sites.Methods The sample was drawn from 19 sites (196 individuals of both sexes) from the east coast of the Yucatan Peninsula, as well as from inland localities within the boundaries of Quintana Roo. Both dental and osteological stress indicators were analyzed, and crosstabs were applied for absolute and relative frequencies and their corresponding χ2 and F Fisher analyses. The osteopathological index of the coastal and inland sites of the Classic period were compared over time between the Classic coastal inhabitants and the Postclassic coastal inhabitants so as to understand how life conditions changed over time. The Mantel-Haenszel odds ratio, with the crosstabs controlling for sex (males and females), was also carried out.ResultsThere are low frequencies of dental pathologies and anemia present in both the coastal and inland populations of Quintana Roo in the Classic and Postclassic times. Only the presence of periostitis is highly common in both types of site, and this is the only indicator with significant differences. The dental pathologies, anemia and periostitis, in general, present a slight upward trend in both the coastal and inland populations over time. The coastal populations have fewer frequencies of the above than the inland sites whilst, in the Postclassic period, both the coastal and inland sites register increased frequencies of all the indicators. Linear enamel hypoplasia (LEH) is the only indicator that does not follow this tendency.Conclusions The analyzed indicators are in accord with the general tendency reported in the literature. The results revealed a general trend whereby the Classic inland sites display poorer life conditions than the Classic coastal sites. In the Postclassic period, this pattern changed because the frequencies of all stress indicators increased. The explanations regarding this tendency are related to the differential access to food resources between regions; coastal people had a varied diet and better sources of protein, taking into account the culture of alimentation, the type, and the sources (in general, fish) that have an important impact on the absorption of micronutrients and therefore greater impact on local health conditions. Also, it is plausible that they were able to access imported food through commerce (such as meat and vegetables/corn). The decline in health of the coastal people in the Postclassic period was probably associated with social stratification, increasing militarism, changes in the economic corpus, new pathogens, and the decline of the power structures prevailing throughout the Classic period.

    ABSTRACT: Objectives The adaptation of human beings to a high altitude environment during growth has been reported in several populations but is less known for Tibetans. The objective of this study was to investigate similarities and differences of Tibetans in patterns and characteristics of physical growth and development in comparison to other high altitude populations.Methods We measured the stature, weight, chest circumference and sitting height of 2,813 healthy children and adolescents aged 6- to 21-year-old living at 3,658–4,500 m in Tibet, China, and compared them with published data from other high altitude populations. Eligible participants must have been born and raised in Tibet, and both their parents’ families have to be Tibetan for at least the past three generations.ResultsThe physical growth and development of children and adolescents in Tibet and the Andes followed similar patterns, such as delayed growth, short stature and sitting height, and large chest dimensions. Relative to stature, Tibetan sitting heights are similar to Andeans, but chest circumferences are smaller.Conclusions Findings from this study reinforce the conclusion that Tibetan and Andean populations have adapted differently to high altitude hypoxia. The physical features of each population may result from unique adaptation to hypoxia, as well as socio-ecological factors, such as poor nutrition. Am. J. Hum.
