“…The rural Yucatec Maya study community is located in the Puuc region of Yucatan about 140 km southwest of Merida. The community consists of ~500 subsistence maize agriculturalists whose economy, demography and childcare practices have been studied extensively since 1992 (Kramer, 2005; Kramer, 2009; Kramer & Veile, 2018; Veile, Faria, et al, 2019; Veile & Kramer, 2018). The past 20 years have seen the introduction of electricity, running water, a paved road, motorized vehicles, mechanized farming, schools, and a health clinic, yet villagers maintain a largely traditional diet and agricultural practices.…”

“…Mothers engage in domestic tasks (e.g., cooking, laundry, and childcare) and some field work; some earn cash by participating in government‐run craft cooperatives (Hackman & Kramer, 2021). The rural Maya are bilingual in Spanish and Maya, with Maya being the predominate language spoken within households and children's first language (Padilla‐Iglesias & Kramer, 2021) Previous studies showed a median breastfeeding duration of 30.64 months (95% CI: 29.62–31.66, n = 88), with the introduction of complementary foods occurring at a median of 5.7 ( SD =2.2, range =2–12, n = 58) months (Veile, Faria, et al, 2019; Veile & Kramer, 2015). Mothers completed on average 6.52 ( SD =3.10, n = 73) years of schooling (Kramer et al, 2021; Veile, Valeggia, & Kramer, 2019).…”

“…For example, negative health outcomes tend to be exacerbated in marginalized indigenous populations experiencing urbanization and the nutrition transition (Cockx et al, 2018; Goryakin et al, 2017; Gracey & King, 2009; Harris et al, 2019; King et al, 2009; Malik et al, 2013; Mora‐García et al, 2020; Valeggia & Snodgrass, 2015; Varela‐Silva et al, 2012). In addition, early‐life factors may culminate in differential outcomes across rural and urban settings (Garraza et al, 2016; McDade et al, 2005; Mueller et al, 2015; Mushtaq et al, 2011; Opara et al, 2012; Ortiz et al, 2014; Veile, Faria, et al, 2019).…”

Early‐life conditions shape childhood growth and are affected by urbanization and the nutritional transition. To investigate how early‐life conditions (across the “first” and “second” 1000 days) are associated with rural and urban children's nutritional status, we analyzed anthropometric data from Maya children in Yucatan, Mexico. We collected weight, height and triceps skinfold measures, then computed body mass and fat mass indices (BMI/FMI), in a cross‐sectional sample of 6‐year‐olds (urban n = 72, rural n = 66). Demographic, socioeconomic and early‐life variables (birthweight/mode, rural/urban residence, household crowding) were collected by maternal interview. We statistically analyzed rural‐urban differences in demographic, socioeconomic, early‐life, and anthropometric variables, then created linear mixed models to evaluate associations between early‐life variables and child anthropometric outcomes. Two‐way interactions were tested between early‐life variables and child sex, and between early‐life variables and rural‐urban residence. Results showed that rural children were shorter‐statured, with lower overweight/obesity and cesarean delivery rates, compared to urban children. Household crowding was a negative predictor of anthropometric outcomes; the strongest effect was in boys and in urban children. Birthweight positively predicted anthropometric outcomes, especially weight/BMI. Birth mode was positively (not statistically) associated with any anthropometric outcome. Cesarean delivery was more common in boys than in girls, and predicted increased height in urban boys. In conclusion, urbanization and household crowding were the most powerful predictors of Maya 6‐year‐old anthropometry. The negative effects of crowding may disproportionately affect Maya boys versus girls and urban versus rural children. Early‐life conditions shape Maya children's nutritional status both in the “first” and “second” 1000 days.

Exploring infant feeding practices and associated factors among HIV-positive mothers attending early infant diagnosis clinic in Northern Uganda

This study assessed the infant feeding practices and their determinants among HIV positive mothers with infants (0-12 months).A cross sectional study design adopting qualitative and quantitative data collection procedures was used. This study was carried out from Awach Health Center IV in Gulu city, Uganda. We enrolled 108 adult participants who were HIV positive mothers with an infant from October to December 2021. Semi structured questionnaire and FGD guide were used in data collection. Data was collected, edited, coded and entered into Epi info. The data was analysed using SPSS version 22. Qualitative data was analysed using Atlas.ti software.Of the 108 mothers, 83/108 (77%) practiced exclusive breastfeeding while 25/108 (23%) practiced mixed feeding. Qualitative results also showed that exclusive breastfeeding was the preferred choice. Majority of the respondents 104/108 (96.3%) believed HIV can be transmitted to their babies. Factors associated with infant feeding practices at multivariant level analysis at 5% significance were age of the child (OR=0.706, 95% CI: 0.2100.988), income level (OR=1.296, 95% CI: 1.150-10.631).Majority of mothers had good knowledge about prevention of mother to child transmission.Mothers should deliver from hospitals, more sensitizations for these mothers to appreciate the benefits of exclusive breastfeeding.

“…This strategy is essential to understanding species‐wide variation in reproductive functioning. Many overt features of human reproduction (eg, the number and timing of births (Beall & Leslie, 2014), breastfeeding behaviors (Veile, Faria, Rivera, Tuller, & Kramer, 2019), and menstrual bleeding (Fitzpatrick, 2018)) can be studied without recourse to measuring hormones. Nonetheless, the addition of these and other biomarkers opens a window into reproductive mechanisms not otherwise accessible.…”

A detailed understanding of female reproductive functioning is important to many disciplines including anthropology, evolutionary theory, demography, psychology, and biomedicine. In this article, I describe strategies and methods that have been used successfully in community‐based studies of human reproduction, many in remote locales, to produce high quality biomarker data. These techniques are applicable to a wide range of research questions and populations, and to persons from adolescence through senescence. I give particular attention to the inherent challenges imposed by the cyclical and somewhat unpredictable nature of the hypothalamic‐pituitary‐ovarian axis including the necessity and difficulty of ascertaining the timing and occurrence of ovulation, the limits of different sampling regimes for capturing fluctuations in reproductive hormones, and the critical importance of recognizing and, when possible, reducing selection bias. I discuss the relative advantages and disadvantages of collecting saliva, urine, and dried blood spots, and describe some of the subtleties involved in collecting contamination‐free samples. Once samples are collected, they must be stored in a manner that minimizes degradation; I describe techniques to keep samples cold even without access to electricity or dry ice. I also discuss various issues that should be considered during initial discussions with a laboratory and when samples are assayed by the laboratory. I include examples of techniques that have worked well in actual field studies, and examples of flawed analytical approaches that should be avoided. With these and other tools, even under technology‐sparse conditions, researchers can investigate variability in human physiology across the breadth of human habitats.
