title: [Epidemiology of low birth weight in Tunisia].
abstract: Our study aims to assess the determinants and the frequency of low birth weight (LBW) in the health district of Monastir (Tunisia). The study was carried out over a three-year period, beginning in January 1995 and ending in December 1997. According to the Monastir district's childbirth register, 1,194 of the 21,393 newborns delivered were babies born with a low birth weight (LBW rate of 5.6%). Common characteristics among the LBW infants were the following: females are more often affected than males (sex ratio of 1.25); 22% of cases were twins; one-third were premature births (< 37 weeks). This study of the determinants of LBW demonstrates that there are several factors linked to the occurrence of LBW such as the mother's age, the number of times she has given birth, an interval between pregnancies of less than 24 months, lack of prenatal care, and the female sex of the baby.
