Studies investigating the predictors of growth in infants born to HIV-infected women in developing countries are limited. Using data from 886 Tanzanian HIV-infected women and their infants, we examined the impact of maternal socioeconomic and immunological status, infant characteristics at birth, and HIV, diarrhea and respiratory infections on infants'(More)
BACKGROUND Infant feeding in communities with a high prevalence of HIV and AIDS is a potential challenge for mothers who must ultimately decide how to feed their infants within contexts that constrain their choices. METHODS We investigated how infant feeding policy recommendations translate into maternal infant feeding decisions and practices using(More)
BACKGROUND Low birth weight and subsequent rapid child growth are associated with later blood pressure levels. The role of maternal and child nutrition in this association remains unclear. METHODS We studied 450 men and women (ages 21-29 years) born during a randomized trial of protein-energy supplementation (Atole) vs low energy/no protein(More)
The purpose of this manuscript is to review the impact of supplementation with vitamins E and C, carotenoids, and the B vitamins on parameters of innate and adaptive immune function as reported from clinical trials in humans. There is evidence to support causal effects of supplementation with vitamins E and C and the carotenoids singly and in combination on(More)
Human galactose-1-phosphate uridyltransferase (hGALT) is a central enzyme in the conserved pathway by which galactose is converted to energy, UDP-galactose and UDP-glucose. A natural mutation that deleted -119 to -116 bp (delGTCA) of the promoter decreased hGALT mRNA and enzyme activity and prompted analysis of hGALT gene regulation. Regulatory domains were(More)
We examined the prospective associations between breast milk concentrations of erythropoietin, a factor with trophic effects on infant gut epithelia, and the risk of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) through breast-feeding in a study of 59 MTCT cases and 116 controls nested within a cohort of antiretroviral-naive(More)
Appropriate home management can alleviate many of the consequences of diarrhea including malnutrition, impaired development, growth faltering, and mortality. Maternal cognitive ability, years of schooling, and acquired academic skills are hypothesized to improve child health by improving maternal child care practices, such as illness management. Using(More)
The effects of maternal academic skills on infant-feeding practices are not clear. From 1996 to 1999, the authors collected information on infant-feeding practices from birth on infants born to 279 mothers from 4 rural villages in Guatemala. They examined associations between maternal academic skills and indicators for the initiation of exclusive(More)
