Recently, the United States (US) Food and Drug Administration (FDA) launched a Closer to Zero Action Plan assess risks of develop action levels for certain heavy metals in food including cadmium (Cd). The problem foodborne metal contamination has taken on new urgency, thanks part 2021 US Congressional Report detailing high found infant food. Our risk assessment aids this FDA by estimating American population's Cd exposures food, age group consumption patterns high-risk foods; determining...
Poor nutritional status in pregnancy expressed as low mid-upper arm circumference (MUAC) is associated with birth weight. The study aims were to assess the of pregnant Ethiopian women using MUAC and examine association nutrition-specific nutrition-sensitive factors, baseline data a prospective longitudinal observational cohort conducted three rural districts Oromia region Ethiopia. Recruitment into was rolling over period nine months, used for this analysis collected while between 12–32...
Naturally occurring aflatoxins may contribute to poor growth and nutritional statuses in children.We analyzed the relationship between contemporary lagged aflatoxin exposure 1) length-for-age z-score (LAZ); 2) length, knee-heel stunting, weight-for-age (WAZ), weight-for-length (WLZ).We conducted a longitudinal birth cohort study involving 1675 mother-infant dyads rural Nepal. Participants were repeatedly visited from pregnancy 2 years of age (2015-2019). One blood sample was collected during...
Abstract Evidence of the impact exposure to multiple mycotoxins and environment enteric dysfunction (EED) on child growth is limited. Using data from a birth cohort study, objectives this study were (a) quantify (serum aflatoxin [AFB 1 ] ochratoxin A [OTA], urinary fumonisin [UFB deoxynivalenol [DON]), as well EED (lactulose:mannitol [L:M] ratio); (b) examine potential combined effects mycotoxin growth. Multivariate regressions used identify associations between measurements (length, weight,...
Consumption of milk is linked to improved nutrient intake and reduced risk child malnutrition in low middle-income countries. However, these benefits are contingent on the safety quality milk. Milk consumption may alleviate widespread rural Ethiopia, but milk-borne contaminants also compromise health. We aimed to: i) identify types dairy feeds used, their storage conditions, potential aflatoxin contamination; ii) assess stakeholders' knowledge about contamination along value chain; iii)...
Abstract Background Aflatoxins are found in diverse foods widely consumed worldwide. This study investigated the association between aflatoxin exposure and (a) consumption of specific foods, (b) dietary diversity (DD), (c) seasonality. Methods Women enrolled AflaCohort Study Banke, Nepal ( n = 1648) were asked how often they ate certain food items past 7 days 24 h. Serum B 1 -lysine (AFB -lys) adduct levels, measured during pregnancy, determined using high-performance liquid chromatography....
Anemia in pregnancy is associated with higher risk of low birth weight and both maternal perinatal mortality. While previous studies Ethiopia have examined factors anemia, which are the most important determinants anemia this population remain unclear. The objective study was to examine association between status pregnant women different health, behavioral, socioeconomic Oromiya province Ethiopia.This used enrollment data from a longitudinal cohort conducted Ethiopia. Survey on household...
Early-childhood development (ECD) is an important determinant of a child’s cognitive ability, learning, productivity, and lifetime earnings. Animal-sourced food (ASF), which rich source high-quality protein micronutrients, has been linked with ECD outcomes. This study investigates the relationship between number, frequency, cumulative consumption ASF at 6, 9, 12, 18 months age outcomes 24 age, controlling for physical growth. The uses data collected from 701 mother–child pairs observational...
Background Anemia through pregnancy is highly correlated with poor birth outcomes, especially low weight (LBW). The Nepal DHS 2011 reports prevalence of anemia in pregnant women at 48%. Objective objectives are to determine levels enrolled a longitudinal cohort and understand the factors associated serum hemoglobin. Methods Data from rolling study (n=1675 women) being conducted Banke District Nepal. At recruitment, one venous blood sample was collected each woman along anthropometry (weight,...
A growing body of mainly cross-sectional evidence suggests an association between mycotoxins, particularly aflatoxin exposure, and poor linear growth in children. We describe the design methods a rigorous longitudinal birth cohort study aimed to deepen our understanding this hypothesized relationship validate dried blood spots as less invasive, low-cost collection method for venous samples. The AflaCohort was conducted Banke district Nepal from 2015 2019. total 1,675 pregnant women ages...
In Sidama, Ethiopia, animal-source foods can be difficult to access. Milk has important nutrients for child growth, but carries the risk of aflatoxin M1 (AFM1) contamination. AFM1 is a metabolite mycotoxin B1 (AFB1) in dairy feed; cows secrete milk when their feed contains AFB1 produced by Aspergillus fungi maize, nuts and oilseeds. It unknown whether compromises growth health. This protocol paper describes our study Sidama determine impact consumption on first 18 months life. We will...
Exposure to airborne particulate matter of diameter less than 2.5 microns (PM2.5) is associated with cardiovascular diseases (CVD) and chronic obstructive pulmonary disease (COPD). In agriculture, the practice tilling generates PM2.5 emissions that can jeopardize human health. This paper estimates annual deaths disability-adjusted life years (DALYs) from CVD COPD attributable corn, soybean, cotton, wheat tillage in contiguous United States. We propose a conceptual framework for an optimal...
Background In Egypt, rates of child overweight and obesity are consistently increasing. While progress has been made in the reduction stunting, Egypt's rate 21% is still higher than countries region that have same GDP. Objectives The objectives were to examine understand trends variability malnutrition all its forms (over under nutrition) Egyptian children five, across time, regions socio‐economic status associated factors. Methods DHS data from 1988 2014 downloaded cleaned analyzed using...
Background Rates of weight gain in pregnancy are associated with infant for age, length age and predictive postnatal growth at 6 months age. The study examines factors linked low mid upper arm circumference (MUAC) pregnant women Banke Nepal. Objective objectives this analysis to examine the MUAC status enrolled a longitudinal birth cohort understand MUAC. Methods Data these analyses from rolling (n=1675) being conducted 17 Village Development Committees (VDCs) District At recruitment...
Stunting and wasting in early life increase the risk of mortality. While assessed diagnosed as individual conditions, these two forms malnutrition often coexist within same populations possibly individual. The main objective our analysis was to assess magnitude stunting among Nepali infants first 12 months investigate association on later stunting. For this analysis, we utilized anthropometric data collected a longitudinal birth cohort study with 1675 maternal-infant dyads. Birth length...
