Abstract The cost of ready‐to‐use therapeutic food ( RUTF ) used in community‐based management of acute malnutrition has been a major obstacle to the scale up of this important child survival strategy. The current standard recipe for RUTF [peanut‐based RUTF ( P ‐ RUTF ) ] is made from peanut paste, milk powder, oil, sugar, and minerals and vitamins. Milk powder forms about 30% of the ingredients and may represent over half the cost of the final product. The quality of whey protein concentrates 34% ( WPC 34) is ...

The objective of this study was to examine the prevalence and predictors of food insecurity among people living with HIV (PLHIV) in two rural communities in Zambia. A cross-sectional sample of 101 PLHIV was surveyed using the Household Food Insecurity Access Scale. In multivariable linear regression models, income, household possessions, and perceived coping strategies were significantly associated with decreased food insecurity. Debt and perceived mental distress were significantly associated with ...

The novel Coronavirus Disease-2019 which was first reported on 31st December, 2019 in Wuhan city, China has resulted in over 889, 256 deaths and over 27 million infections worldwide. In Zambia there have been a total of 295 deaths among which there were 214 brought-in-dead (BID). This high number of BIDs raises critical questions about the health seeking behaviour among the Zambian population. There is need to investigate drivers of community deaths. Here we postulate possible causes and suggest ...

OBJECTIVE Recent studies in humans and animal models of obesity have shown increased adipose tissue activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which amplifies local tissue glucocorticoid concentrations. The reasons for this 11β-HSD1 dysregulation are unknown. Here, we tested whether 11β-HSD1 expression, like the metabolic syndrome, is “programmed” by prenatal environmental events in a nonhuman primate model, the common marmoset monkey. RESEARCH DESIGN AND METHODS We used a “fetal ...
