Lee E, et al. Reducing low birthweight through home visitation: a randomized controlled trial. Am J Prev Med. Feb 2009;36(2):154-160.
This study assessed the effectiveness of a prenatal home visitation program in reducing adverse birth outcomes among socially disadvantaged pregnant women and adolescents. The risk of delivering a low-birthweight baby was significantly lower for the intervention group. The risk was further reduced for mothers who were exposed to the intervention at a gestational age of 24 weeks or fewer.
