    ABSTRACT: Objectives: This study sets out to investigate the intergenerational associations between the body mass index (BMI) of parents and the body composition of their offspring. Methods: The cross-sectional data were analyzed for 511 parent-offspring trios from London and south-east England. The offspring were aged 5-21 years. Parental BMI was obtained by recall and offspring fat mass and lean mass were obtained using the four-component model. Multivariable regression analysis, with multiple imputation for missing paternal values was used. Sensitivity analyses for levels of non-paternity were conducted. Results: A positive association was seen between parental BMI and offspring BMI, fat mass index (FMI), and lean mass index (LMI). The mother's BMI was positively associated with the BMI, FMI, and LMI z-scores of both daughters and sons and of a similar magnitude for both sexes. The father's BMI showed similar associations to the mother's BMI, with his son's BMI, FMI, and LMI z-scores, but no association with his daughter. Sensitivity tests for non-paternity showed that maternal coefficients remained greater than paternal coefficients throughout but there was no statistical difference at greater levels of non-paternity. Conclusions: We found variable associations between parental BMI and offspring body composition. Associations were generally stronger for maternal than paternal BMI, and paternal associations appeared to differ between sons and daughters. In this cohort, the mother's BMI was statistically significantly associated with her child's body composition but the father's BMI was only associated with the body composition of his sons. Am. J.

    ABSTRACT: Objectives: Growth patterns in early life are increasingly linked with subsequent cardio-metabolic risk, but the underlying mechanisms require elucidation. We have developed a theoretical model of blood pressure, treating it as a function of homeostatic metabolic capacity, and antagonistic metabolic load. We sought to differentiate prenatal and postnatal components of metabolic capacity, and to identify intergenerational contributions to offspring capacity and load. Methods: We followed up at 8 years a cohort of children originally recruited into a randomized trial of maternal micronutrient supplementation in pregnancy. Maternal anthropometry was measured at recruitment. Offspring anthropometry was measured at birth, 2 years and 8 years. Offspring blood pressure, kidney size, and body composition were measured at 8 years. Regression analysis was used to investigate potential associations of maternal phenotype, birth phenotype, and current body composition with kidney size and blood pressure. Results: Blood pressure was positively associated with body fat, but negatively associated with birth weight and relative leg length. Kidney size was positively associated with birth weight but not with relative leg length. Adjusting for adiposity, blood pressure was independently negatively associated with birth weight, relative leg length, and kidney length. Maternal height and BMI predicted offspring size at birth and at 8 years, but not blood pressure. Conclusions: Our data provide support for the capacity-load model of blood pressure in Nepalese children. Fetal and postnatal growth and kidney dimensions all contribute to metabolic capacity. Maternal phenotype contributed to offspring capacity and load, but these associations did not propagate to blood pressure. Am. J. Hum.

    ABSTRACT: Objective: Genetically isolated and homogenous populations are ideal for detecting genes underlying common complex diseases. The use of isolated populations with reduced disease heterogeneity has led to significant gene discoveries in the past. The aim of this pilot study was to assess the prevalence of cardiovascular disease (CVD) risk phenotypes in a genetically homogenous population of Parsi Zoroastrians in the United States. Methods: Anthropometrics, blood pressure, and medical history were collected from 152 men and 186 women participating in a pilot study as part of the Parsi Family Study. The relative pairs used in the study included 60 parent-off springs, 28 siblings, 6 grandparent-grandchild, 7 avuncular, 18 half-siblings, 7 half-avuncular, and one half-first cousin. Estimates of genetic and environmental influence were calculated using a maximum likelihood-based variance components method implemented in SOLAR. Results: The prevalence of overweight/obesity in adults (62%) was on par with current US prevalence. Hypertension and prehypertension were prevalent in 16% and 46% of the participants, respectively. The quantitative genetic analysis revealed significant heritabilities for all anthropometric phenotypes (P < 0.05). Significant phenotypic correlations were found between blood pressure and anthropometric phenotypes (P < 0.001), whereas significant genetic correlation was found for only diastolic blood pressure and fat free mass (rhoG = -0.88, P < 0.05). Conclusion: These preliminary data show significant additive genetic effects on CVD-related phenotypes in this population. Our findings represent the first epidemiological data in Parsi Zoroastrians in the United States and offer excellent promise for future genetic studies in this population. Am. J. Hum.

    ABSTRACT: Objectives: This study investigated morning salivary cortisol concentration in relation to total body fat composition among community-dwelling Papua New Guinean adults. Methods: In addition to demographic and anthropometric measurements, saliva was collected in a single morning from 478 residents in Eastern Highlands Province and Madang Province. Results: After adjusting for age, region, and occupation, the morning salivary cortisol concentration was significantly negatively correlated with body mass index among men (B = -0.01, P < 0.05) and women (B = -0.013, P < 0.05), and waist circumference (B = -0.007, P < 0.05), waist-to-hip-ratio (B = -1.214, P < 0.05), and subscapular-to-triceps skinfold-thickness ratio (B = -0.045, P < 0.05) among men. Men with total or abdominal body fat mass known for elevated risk of non-communicable diseases displayed lower cortisol compared to men without such risk. Conclusions: Papua New Guinean adults with increased accumulation of body fat showed reduced cortisol concentration in morning saliva. Am. J. Hum. Biol., 2016. © 2016 Wiley Periodicals, Inc.

    ABSTRACT: Objective: The aim was to test the hypothesis that the difference in body mass index (BMI) between twins and singletons may be attributed to a difference in birth weight. Methods: Data from the Medical Birth Registry of Norway were linked with data from the Norwegian Conscript Service. This study used data on 411,186 males who were born in single or twin births in Norway during 1967 to 1984, and who were examined at the mandatory military conscription (98% were examined the year they turned 18 or 19 years of age). Results: The difference in BMI between singletons and twins was 0.49 kg/m(2) (95% confidence interval [CI]: 0.41, 0.56) after adjustment for background factors and gestational age at birth. When birth weight was added to the model, the difference was reduced to 0.17 kg/m(2) (95% CI: 0.09, 0.25). The corresponding figures for sibships that included both singletons and twins were 0.63 kg/m(2) (95% CI: 0.39, 0.86) and 0.38 kg/m(2) (95% CI: 0.06, 0.70) when twins were compared with their singleton brothers. In both the analysis of the total study population and the analysis of the sibships, birth weight was significantly associated with the BMI after adjustment for twin status, gestational age at birth, and background factors. Conclusions: Male twins born in Norway during 1967 to 1984 had lower BMI at the military conscription than had singletons, and a part of this difference may probably be attributed to lower intrauterine growth rate among twins.

    ABSTRACT: Objectives: How important is it to be able to reconstruct the lives of a highly diverse, historically recent macroethnic group over the course of 400 years? How many insights into human evolutionary biology and disease susceptibilities could be gained, even with this relatively recent window into the past? In this article, we explore the potential ramifications of a newly constructed dataset of Four Centuries of African American Biological Variation (4Cs). Methods: This article provides initial lists of digitized variables formatted as SQL tables for the 17th and 18th century samples and for the 19th and 20th century samples. Results: This database is dynamic and new information is added yearly. The database provides novel opportunities for significant insights into the past biological history of this group and three case study applications are detailed for comparative computational systems biology studies of (1) hypertension, (2) the oral microbiome, and (3) mental health disorders. Conclusions: The 4Cs dataset is ideal for interdisciplinary "next generation" science research and these data represent a unique step toward the accumulation of historically contextualized Big Data on an underrepresented group known to have experienced differential survival over time.

    ABSTRACT: Objectives: Although children are typically raised in familial care networks, not all children have access to kin. Here, I investigate the growth measures of children living in two different residential contexts in Jamaica: institutional care settings and familial homes. Methods: This cross-sectional study sampled individuals ranging from 5-18 years old, residing in children's homes (N = 113 participants) and familial homes (N = 103 participants). Anthropometric measurements and interview data were collected from all participants. Height for age z-scores (ZHFA) and weight for age z-scores (ZWFA) were calculated using the 2007 WHO standards. Body fat was estimated from tricep and suprailiac skinfold thickness. Between group comparisons were completed using analysis of covariance (ANCOVA), with age included as a covariate. Significance was accepted at P ≤ 0.05. Results: Context was more predictive of condition among children than adolescents. Both girls and boys ages 5-11 years living with family members had higher mean height and weight for age, and summed skinfold thickness measures, than their peers living in children's homes. Fewer correlations between home setting and growth measurements were found among 12-18 year olds. Notably, although children were randomly assigned to children's homes, boys in a single-sex institution did not differ in growth measurements from boys living with family members. Conclusions: Younger children who lived with family members had better growth measurements than their peers living in institutional settings. However, improved growth measures for children living in one home were correlated to nonconventional counseling practices, and nutritional policies that mirror some aspects of familial care. Am. J.

    ABSTRACT: Objective: Understanding the genetic origin of the Hb D-Los Angeles hemoglobin may elucidate population interactions such as movements, migrations, and environmental effects on mutation mechanisms in human biology throughout history. Our study aimed to understand the genetic origin of Hb D-Los Angeles based on haplotype data, observed in the Denizli province of Turkey. Methods: We studied DNA samples from 40 unrelated patients with abnormal hemoglobin Hb D-Los Angeles and 59 unrelated healthy subjects from our DNA bank. Possible associated haplotypes, HWE, genetic diversity and population differentiation, population genetic structure analysis and historical-demographic analysis for the two populations were determined by Arlequin ver. 3.5. Results: Molecular diversity results from the two populations show that both populations are genetically similar as far as development and expansion during the historical period. Historical gene flow results show high gene flow between the two populations. SSD and rg tests failed to reject the null hypothesis of population expansion which is consistent with unimodal distribution. Our estimated τ values show that the average time since the demographic expansion for normal and Hb D-Los Angeles populations ranged from approximately 42,000-38,000 ybp, respectively. Conclusions: Our data suggest that the Hb D-Los Angeles population originated within the normal population in Denizli, Turkey. Our results support the hypothesis that the Hb D-Los Angeles mutation may have originated in the Mediterranean area, independent from other populations such as India and China. The evaluation of such data may contribute valuable information to anthropological, paleoclimatic, archaeological, and phylogeographical approaches to human biology throughout the historical period.

    ABSTRACT: Objectives: Using ethnographic interviews and biological measures, this article investigates changing health and nutrition of a hunter-gatherer population transitioning from a forest-based subsistence system to a horticultural and market-driven lifestyle. Methods: This study represents biological and dietary recall data for adult female foragers (18+; n = 60) across two villages, Mossapoula (MS) and Yandoumbé (YDBE), in the Dzanga Sangha Protected Areas (APDS), Central African Republic (CAR). Standard anthropometric measurements (height, weight, skinfolds) and hemoglobin values were collected to assess short-term nutritional status. Results: BMI was similar across all three age classes in YDBE, but differed amongst women of MS (ANOVA; F = 6.34, df = 30, P = 0.005).Values were lowest among the older women in older age class 3 who also had the greatest number of dependents. Overall SS values were significantly negatively correlated with the number of biological children (r = -0.33, P = 0.01) in both villages. Conclusions: Here, we identify older BaAka women, caring for their own children and grandchildren, as particularly vulnerable to economic changes and food insecurity. We found older women, especially those in a community with greater restrictions on access to forest resources to have more dependents, reduced market integration, and low BMI relative to younger women in the population.

    ABSTRACT: Despite longstanding interest among human biologists in autonomic responses to socioecological context or culture change, the adoption of autonomic measures has been limited by methodological challenges. Catecholamine secretion is the most direct measure, but not all study designs are amenable to urinary sampling, and blood pressure lacks specificity to the parasympathetic or sympathetic division of the autonomic nervous system. This article reviews three alternative approaches for measuring autonomic responses: salivary α-amylase as a nonspecific autonomic marker, respiratory sinus arrhythmia as a specific parasympathetic marker, and the pre-ejection period as a specific sympathetic marker. Study design considerations are discussed in detail, including ambulatory sampling protocols that permit the evaluation of autonomic responses to everyday life. Researchers interested in how culture and social experience "get under the skin," as well as those concerned with the evolution of social engagement, can benefit from these well-validated biomarkers that are nevertheless relatively novel in human biology.

    ABSTRACT: Objectives: To investigate the total, direct and mediated (by fatness) association of physical activity (PA) with fitness. Methods: Body fat percentage (%Fat), maximal oxygen uptake (VO2max ) and PA were measured directly in 18-year-olds (n=202) and their association analyzed with a linear regression-based mediation analysis after controlling for sex. Results: The total association between PA and VO2max was significant (c=0.66, P<0.001) and was significantly mediated by %Fat (ab=0.25, 95% CI: 0.04-0.49). The direct association was also significant (ć=0.41, P<0.001). Conclusion: Physical activity is associated with VO2max in 18-year-old adolescents but a little over a third of that association is mediated by %Fat. Regardless of fatness, PA is important for fitness in this age group. Am. J. Hum. Biol., 2015.© 2015 Wiley Periodicals, Inc.
