2003 JUN 12 - (NewsRx.com & NewsRx.net) -- Malaria infection and low CD4 cell counts are among the factors limiting weight gain in pregnant HIV-positive women.
"Progression of HIV disease is often accompanied by weight loss and wasting," researchers at Harvard University explained. "Gestational weight gain is a strong determinant of maternal and neonatal outcomes; however, the pattern and predictors of weight gain during pregnancy among HIV-positive women are unknown."
To identify these factors, E. Villamor and colleagues "obtained monthly anthropometric measurements in a cohort of 957 pregnant women from Tanzania who were HIV infected," and "estimated the weekly rate of weight gain at various points during the second and third trimesters of pregnancy and computed rate differences between levels of sociodemographic, nutritional, immunologic, and parasitic variables at the first prenatal visit."
"The change in mid-upper arm circumference (MUAC) from baseline to delivery was also examined," they noted in the Journal of Acquired Immune Deficiency Syndromes. "The rate of weight gain decreased progressively during pregnancy. There was an average decline of 1 cm in MUAC between weeks 12 and 38."
"Lower level of education and helminthic infections at first visit were associated with decreased adjusted rates of weight gain during the third trimester," study data showed. "High ...
