Objective: ascertaining whether intercurrences present during pregnancy increased the chances of a mother bearing a child having low birth weight (LBW). Method: this was a case and control study carried out between April and November 2003 in Rio Grande county/RS, Brazil. Data was collected by means of a questionnaire applied to 547 mothers who gave birth in this county’s two hospitals’ maternity units. Outcome: the presence of transitory or chronic arterial hypertension and the threat of miscarriage during pregnancy were positively connected to the results (p = 0.008 and p= 0.01, respectively) thereby increasing the mothers’ risk of having LBW babies (OR = 3.77; 1.40-10.17 95% CI and OR = 6.27; 1.53-25.76 95% CI, respectively). Conclusion: providing differential prenatal assistance to high- and low-risk pregnant women is one of the preventative measures which can be taken for intercurrences during pregnancy and consequently for LBW.
