[Association between malaria and low birth weight in Yaounde, Cameroon].

INTRODUCTION

Low birth weight (LBW) is an important predictor of newborn survival and development. Given its pathophysiology, malaria is presumed to be one of the risk factors for low birth weight. This study aims to determine the association between malaria in pregnant women (PW) and LBW (weight < 2500 g).

METHODS

We conducted a case-control analytical study based on the administration of a questionnaire and an observation chart. We calculated the crude odds ratio (OR) and the adjusted odds ratio to determine this association. Logistic regression was applied to recognize the variables which act as determinants of the issue under discussion.

RESULTS

This study involved 156 women (78 cases and 78 controls). The prevalence of LBW was 12.32% (105/852); 41.02% (64/156) of women had had malaria during pregnancy and 42.14% of parturients had received three doses of IPT (intermittent preventive treatment). A significant association between malaria and LBW emerged. Crude odds ratio= 3.75 [P = 0.0001 (p < 0.05)] and adjusted OR = 2.82 [P = 0.01 (p < 0.05)] were calculated taking into account the various confusion factors.

CONCLUSION

Malaria during pregnancy is a factor increasing the risk of LBW. Efforts should be made to improve IPT coverage and the use of long lasting impregnated mosquito nets in order to prevent malaria during pregnancy.
