Environmental Exposures and Covid-19 Experiences in the United States, 2020–2022
Certain environmental exposures are associated with COVID-19 incidence and mortality. To determine whether environmental context is associated with other COVID-19 experiences, we used data from the nationally representative Tufts Equity in Health, Wealth, and Civic Engagement Study data ( n = 1785; three survey waves 2020-2022 for adults in the United States). Environmental context was assessed using self-reported climate stress and county-level …
Seasonal variation in maternal dietary diversity is reduced by small‐scale irrigation practices
Some agricultural practices, such as irrigation, have the potential to buffer seasonal dietary gaps and through increased production and consumption improve diets, particularly of the rural poor relying on subsistence farming but also for rural and urban households purchasing irrigated produce on local markets. The study aimed to evaluate the effect of seasonality and irrigation on women's diet in rural Ethiopia. Using a longitudinal study design…
Aflatoxin exposure in utero and birth and growth outcomes in Tanzania
Some evidence suggests that aflatoxin may contribute to the high prevalence of stunting observed in low-income countries. Whereas several studies have been conducted in West Africa, fewer exist in East Africa and even fewer in nonagricultural contexts. We analyzed serum samples from 400 iron-replete, nonanemic pregnant women from a cohort in Dar es Salaam, Tanzania to determine the extent and magnitude of exposure to aflatoxin and to study the re…
Maternal aflatoxin exposure during pregnancy and adverse birth outcomes in Uganda
Aflatoxins are toxic metabolites of Aspergillus moulds and are widespread in the food supply, particularly in low- and middle-income countries. Both in utero and infant exposure to aflatoxin B 1 (AFB 1 ) have been linked to poor child growth and development. The objective of this prospective cohort study was to investigate the association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes, primarily lower birth weight…
Vitamin D status is associated with underweight and stunting in children aged 6–36 months residing in the Ecuadorian Andes
Objective There is limited knowledge on vitamin D status of children residing in the Andes and its association with undernutrition. We evaluated the vitamin D status of children residing in a low socio-economic status (SES) setting in the Ecuadorian Andes and assessed the association between vitamin D status, stunting and underweight. We hypothesized that children who were underweight would have lower serum 25-hydroxyvitamin D (25(OH)D) levels an…
The association between food insecurity and depressive symptoms severity among pregnant women differs by social support category
Common mental disorders, such as depression and anxiety, affect approximately 16% of pregnant women in low- and middle-income countries. Food insecurity (FI) has been shown to be associated with depressive symptoms. It has also been suggested that the association between FI and depressive symptoms is moderated by social support (SS); however, there is limited evidence of these associations among pregnant women living in low-income and middle-inco…
Reliability and validity of an individually focused food insecurity access scale for assessing inadequate access to food among pregnant Ugandan women of mixed HIV status
Objective To determine the reliability, validity and correlates of measures of food insecurity (FI) obtained using an individually focused food insecurity access scale (IFIAS) among pregnant women of mixed HIV status in northern Uganda. Design A mixed-methods study involving cognitive interviews nested within a cross-sectional survey. Setting The antenatal care clinic of Gulu Regional Referral Hospital. Subjects Survey respondents included 403 pr…
Seasonal Patterns of Gastrointestinal Illness and Streamflow along the Ohio River
Waterborne gastrointestinal (GI) illnesses demonstrate seasonal increases associated with water quality and meteorological characteristics. However, few studies have been conducted on the association of hydrological parameters, such as streamflow, and seasonality of GI illnesses. Streamflow is correlated with biological contamination and can be used as proxy for drinking water contamination. We compare seasonal patterns of GI illnesses in the eld…
Metabolic syndrome in the elderly living in marginal peri-urban communities in Quito, Ecuador
Objective The proportion of the Latin American population aged >60 years is expected to double during the next few decades. Metabolic syndrome (MetS) is associated with high morbidity and mortality worldwide. However, little is known about MetS in Latin America in general, and in Ecuador in particular. The present study aimed to examine the prevalence of MetS and its association with blood micronutrient, homocysteine (Hcy) and C-reactive protein …
Hospitalization of the Elderly in the United States for Nonspecific Gastrointestinal Diseases
The frequency of hospitalization among the elderly in the United States caused by gastrointestinal diseases between 1991 and 2004 increased dramatically, especially hospitalization of elderly individuals with nonspecific diagnoses. We analyzed 6 640 304 gastrointestinal disease–associated hospitalization records in this 14-year period by comparing the peak times of nonspecific gastrointestinal diseases with those of specific diseases. We found th…
