title: Risk factors associated with low birth weight infants in the Malaysian population.
abstract: This study aimed to identify the risk factors which were significantly associated with low birth weight (LBW, <2500 g) infants among the Malaysian population. This was a case-control study carried out at the Tuanku Jaafar Hospital, Seremban, Malaysia over a five-month period. Cases were all infants born with birth weight less than 2500 g. Control infant were selected with the help a random sampling table from among infants with birth weight of > or =2500 g born on the same day in the hospital. Of 3341 livebirths delivered in the hospital, 422 (12.6%) were LBW infants. Logistic regression analysis showed that, after controlling for various potential confounders, the only significant risk factors associated with infants of LBW were gestational age (adjusted odds ratio (OR)=0.6, 95% C.I.: 0.5, 0.6; < 0.0001), maternal pre-pregnancy weight (adjusted OR = 0.97, 95% C.I.: 0.95, 0.99; p < 0.0001), nulliparity (adjusted OR = 3.4, 95% C.I.: 2.2, 5.1; p < 0.0001), previous history of LBW infants (adjusted OR = 2.3, 95% C.I.: 1.4, 3.8; p=0.001) and PIH during current pregnancy (adjusted OR=3.3, 95% C.I.: 1.6, 6.6; p = 0.001). A number of potentially preventable or treatable risk factors were identified to be associated with LBW infants in Malaysia.
