Low birth weight infants born to HIV-seropositive mothers and HIV-seronegative mothers in Chiang Rai, Thailand.

ABSTRACT

The low birth weight (LBW) infant has a much higher risk of mortality and morbidity in infancy and early childhood. This study examined the effects of maternal HIV infection and other risk factors for LBW (< 2,500 g). A retrospective study of mothers who delivered at Mae Chan Hospital from 1997 to 2002 was conducted. Logistic regression was used to adjust for confounding factors. There were 266 infants born to HIV-seropositive mothers and 5,872 infants born to HIV-negative mothers. Low birth weight was significantly associated with maternal HIV status, gestational age, antenatal care, maternal age less than 20 years, and > 35 years. Maternal HIV positive status, young maternal age and gestational age were significant factors after adjusting for potential confounders. No significant effect of hilltribe on LBW was found. The results underline the need for nutritional surveillance and dietary counseling. HIV-seropositive women must receive early and continuing antenatal care for good pregnancy outcomes.
