The Developmental Origins of Obesity and Related Health Disorders – Prenatal and Perinatal Factors

Obesity, and its health-related sequelae (the metabolic syndrome), have recently emerged as a global health crisis. The prevalence of childhood and adult obesity in economically developed and developing countries world-wide has more than doubled over the past decade. While genetic factors, increasingly sedentary lifestyles, and overnutrition have all been cited as important components of the obesity crisis, recent epidemiological and experimental evidence suggests that developmental factors – especially those that occur in utero and during early postnatal life – play a significant role in the pandemic. Research into the \u27developmental origins of health and disease’ (DOHaD) has now firmly established that preand perinatal developmental perturbations which predispose to obesity in adult life can result from a variety of factors, including both nutritional surplus and deficiency, and there is growing evidence that these physiological traits can be passed on epigenetically to subsequent generations. Anthropological perspectives regarding the developmental origins of obesity and its related health problems cannot only shed further light on contemporary ethnic human health disparities, but can offer unique insights into the relevance of the developmental origins of disease to community-based public health interventions

The Effects of daily diabetina tea consumption on glycosylated hemoglobin, fasting glucose and lipid levels, and body mass index in normoglycemic individuals

Type 2 diabetes mellitus is a chronic disease responsible for high levels of morbidity and mortality in the United States, especially among some ethnic minority populations. Diabetina tea, a commercially-available herbal blend tea, is a well known herbal remedy for high blood sugar among Hispanic American diabetics. This study will examine the effect of twice-daily unsweetened Diabetina tea consumption over an 8 week period on glucose (sugar) and lipid (fat) metabolism. Potential effects of Diabetina tea consumption on glucose metabolism will be measured by glycosylated hemoglobin (HbA1c) and fasting glucose tests, while the potential effects of Diabetina tea consumption on lipid metabolism will be measured by fasting blood lipid levels, in addition to body mass index (BMI) and waist circumference (WC) measurements

Prevention of type 2 diabetes in urban American Indian/Alaskan Native communities: The Life in BALANCE pilot study

Objective: The Life in BALANCE (LIB) study is a pilot translational study modeling the Diabetes Prevention Program (DPP) intensive lifestyle coaching intervention among an underserved, high-risk population: American Indians/Alaska Natives (AI/ANs) living in a large urban setting (Las Vegas, Nevada). Research Design and Methods: A total of 22 overweight/obese AI/ANs (age, 39.6 ± 10.4 years; BMI, 34.1 ± 6.3 kg/m2) at increased risk for developing type 2 diabetes (HbA1c \u3e 5.4 (36 mmol/mol) \u3c 6.4 percent (46 mmol/mol) participated in the program between April and December, 2011. Study participants completed a 16 week intensive lifestyle coaching intervention. In addition to obtaining qualitative data regarding opportunities and challenges of applying the lifestyle intervention for AI/AN participants in an urban setting, clinical data, including BMI, waist circumference, blood pres- sure, fasting blood glucose, and blood lipids (HDL, LDL and Triglycerides), were collected. Results: Only 12 of the 22 participants remained in the LIB program at the final post-program follow-up. Participants demonstrated significant decreased waist circumference and elevated HDL cholesterol. Triglycerides manifested the highest percentage change without statistical significance. No significant change was ob- served in blood pressure or fasting blood glucose. Conclusions: LIB participants’ improvements in BMI, waist circumference, HDL cholesterol and triglycerides suggests type 2 diabetes prevention programs aimed at urban AI/ANs show significant potential for reducing the risk of developing type 2 diabetes among this underserved and high risk community. Qualitative data suggest the main challenge for type 2 diabetes prevention specific to this population is a need for improved community outreach strategies

Comparison of placenta consumers’ and non-consumers’ postpartum depression screening results using EPDS in US community birth settings (n=6038): a propensity score analysis

Abstract Background Preventing postpartum depression (PPD) is the most common self-reported motivation for human maternal placentophagy, yet very little systematic research has assessed mental health following placenta consumption. Our aim was to compare PPD screening scores of placenta consumers and non-consumers in a community birth setting, using propensity score matching to address anticipated extensive confounding. Methods We used a medical records-based data set (n = 6038) containing pregnancy, birth, and postpartum information for US women who planned and completed community births. We first compared PPD screening scores as measured by the Edinburgh Postpartum Depression Scale (EPDS) of individuals who consumed their placenta to those who did not, with regard to demographics, pregnancy characteristics, and history of mental health challenges. Matching placentophagic (n = 1876) and non-placentophagic (n = 1876) groups were then created using propensity scores. The propensity score model included more than 90 variables describing medical and obstetric history, demographics, pregnancy characteristics, and intrapartum and postpartum complications, thus addressing confounding by all of these variables. We then used logistic regression to compare placentophagic to non-placentophagic groups based on commonly-cited EPDS cutoff values (≥ 11; ≥ 13) for likely PPD. Results In the unmatched and unadjusted analysis, placentophagy was associated with an increased risk of PPD. In the matched sample, 9.9% of women who ate their placentas reported EPDS ≥ 11, compared to 8.4% of women who did not (5.5% and 4.8%, respectively, EPDS ≥ 13 or greater). After controlling for over 90 variables (including prior mental health challenges) in the matched and adjusted analysis, placentophagy was associated with an increased risk of PPD between 15 and 20%, depending on the published EPDS cutoff point used. Numerous sensitivity analyses did not alter this general finding. Conclusions Placentophagic individuals in our study scored higher on an EPDS screening than carefully matched non-placentophagic controls. Why placentophagic women score higher on the EPDS remains unclear, but we suspect reverse causality plays an important role. Future research could assess psychosocial factors that may motivate some individuals to engage in placentophagy, and that may also indicate greater risk of PPD
