Abstract

We examined the relationship of maternal anthropometry to fetal growth and birth weight among 1005 HIV-infected women in Lilongwe, Malawi, who consented to enrollment in the Breastfeeding, Antiretrovirals, and Nutrition (BAN) Study (www.thebanstudy.org). Anthropometric assessments of mid-upper arm circumference (MUAC), arm muscle area (AMA), and arm fat area (AFA) were collected at the baseline visit between 12 and 30 weeks gestation and in up to 4 follow-up prenatal visits. In longitudinal analysis, fundal height increased monotonically at an estimated rate of 0.92 cm/week and was positively and negatively associated with AMA and AFA, respectively. These latter relationships varied over weeks of follow-up. Baseline MUAC, AMA, and AFA were positively associated with birth weight [MUAC: 31.84 grams per cm increment, 95% CI: 22.18, 41.49 (p<0.01); AMA: 6.88 g/cm2, 95% CI: 2.51, 11.26 (p<0.01); AFA: 6.97 g/cm2, 95% CI: 3.53, 10.41 (p<0.01)]. In addition, MUAC and AMA were both associated with decreased odds for LBW (<2500 g) [MUAC: OR=0.85, 95% CI: 0.77, 0.94 (p<0.01); AMA: OR=0.95, 95% CI: 0.91, 0.99 (p<0.05)]. These findings support the use of MUAC as an efficient, cost effective screening tool for LBW in HIV-infected women, as in HIV-uninfected women.
