“…However, many of them have been carried out in industrialized populations where the relationship of interest may be affected by several relatively “modern” factors. Specifically, compared to individuals living in more traditional communities, urban dwellers tend to have easier access to reliable family planning methods (Daniels, Mosher, & Jones, ) and institutions specializing in the provision of allomaternal care and other forms of social support (Sinha, ), high calorie diets (WHO, ), greater exposure to chemical contaminants (Abass, Emelyanova, & Rautio, ; Bastos et al, ; Díaz et al, ; Gracey & King, ; Kovesi et al, ; UNDESA, ), and lower morbidity and mortality levels (Gracey & King, ; UNDESA, ). All of these conditions have been reported to affect sex ratios (Daniels et al, ; Safe, ).…”

Objective: To evaluate putative links between birth sex ratios (BSR = male:female births) and maternal age in a traditional, agricultural, natural fertility population. Metabolic energy, social support, and the costs and benefits associated with producing sons versus daughters can affect BSR. These variables fluctuate with maternal age. Most studies evaluating links between maternal age and BSR have been based on industrialized populations, which differ importantly from traditional indigenous communities in terms of the aforementioned socio-ecological variables.Materials and methods: We analyze data from 108 mothers and their 603 children living in an agricultural, pronatalist, Kakchiquel Mayan community.Results: A logistic regression model, including linear and quadratic maternal age terms and women-specific random effects, shows a nonmonotonic (p = .028) relationship between log BSR and maternal age. For maternal age ≤ 22, the upper bound of the 95% confidence interval (CI) for BSR is <1, suggesting a bias toward girls. The probability of birthing a son increased early during the average mother's reproductive career, peaked at age 31.3 (approximately 95% CI = 27.1, 35.5), and decreased as she approached her perimenopausal period (p = .014).Discussion: No changes in mating system, population sex ratio, mortality patterns, natural disasters, social risk, or toxic exposures were observed and thus are unlikely to explain our results. At this point, age-related changes in metabolic energy, social support, and costs and benefits associated with offspring sex cannot be excluded as possible explanations. BSR can affect growth, morbidity, and mortality. Thus, our results are relevant to numerous fields, including anthropology, ecology, demography, and public health.

“…According to AMAP reports, environmental exposure is usually an exposure not only to a single substance, but to a mixture of chemicals in the environment. The trends of most “traditional” contaminants have decreasing levels in blood samples of pregnant women; however, new ones, which may have endocrine disruptive effects, have been found in the Arctic populations [ 26 ].…”

Climate change in the Arctic affects both environmental, animal, and human health, as well as human wellbeing and societal development. Women and men, and girls and boys are affected differently. Sex-disaggregated data collection is increasingly carried out as a routine in human health research and in healthcare analysis. This study involved a literature review and used a case study design to analyze gender differences in the roles and responsibilities of men and women residing in the Arctic. The theoretical background for gender-analysis is here described together with examples from the Russian Arctic and a literature search. We conclude that a broader gender-analysis of sex-disaggregated data followed by actions is a question of human rights and also of economic benefits for societies at large and of the quality of services as in the health care.

“…Human exposure to organochlorine pesticides (OCPs), such as dichlorodiphenyltrichloroethane (p,p′-DDT), hexachlorocyclohexanes (β-HCH), chlordanes, hexachlorobenzene (HCB), and mirex, has been a subject for extensive research in recent decades in the Arctic [ 16 , 17 , 18 ]. Although the concentrations of POPs in humans have decreased in most Arctic locations over the past two decades, the levels of oxychlordane, hexachlorobenzene (HCB), 2,2′,4,4′,5,5′-hexabromodiphenyl ether (PBDE153), and perfluorinated compounds (PFCs) remain stable [ 19 ].…”

Persistent organic pollutants (POPs) are heterogeneous carbon-based compounds that can seriously affect human health. The aim of this study was to measure serum concentrations of POPs in women residing in the Euro-Arctic Region of Russia. A total of 204 women from seven rural settlements of the Nenets Autonomous Okrug (NAO) took part in the study. We measured serum concentrations of 11 polychlorinated biphenyls (PCBs) and 17 organochlorine pesticides (OCPs) across the study sites and among Nenets and non-Nenets residents. Measurement of POPs was performed using an Agilent 7890A gas chromatograph equipped with an Agilent 7000 series MS/MS triple quadrupole system. The concentrations of all POPs were low and similar to findings from other Arctic countries. However, significant geographic differences between the settlements were observed with exceptionally high concentrations of PCBs in Varnek located on Vaygach Island. Both ΣDDT (p = 0.011) and ΣPCB (p = 0.038) concentrations were significantly lower in Nenets. Our main findings suggest that the serum concentrations of the legacy POPs in women in the Euro-Arctic Region of Russia are low and similar to those in other Arctic countries. Significant variations between settlements, and between Nenets and non-Nenets residents, were found. Arctic biomonitoring research in Russia should include studies on the associations between nutrition and concentrations of POPs.
