Objective. -To establish fullterm newborn anthropometric parameters to determine the frequency of intrauterine growth retardation and to study mother’ s and socioeconomic risk factors associated with the intrauterine growth retardation in the population in North-Togo. Methods. -Twelve month prospective study in the savana area in North-Togo. One thousand and six alive newborns born after normal single pregnancy, and without severe neonatal diseases were included. Results. -The mean birth-weight± SD was 2938± 421 g. The incidence of low birth-weight was 11,7% . Among mother’ s and socioeconomic risk factors, teenage mothers, mothers with a weight lower than 50 kg or with body mass index lower than 20 kg/m2 had a significantly high risk of having a child with intrauterine growth retardation (Odds ratio=2,71; 2,57; 1,57 respectively). Father’ s job also affected the mother’ s and newborn’ s weight. Conclusion. -The recognition of these easy to identify risk factors should allow specific recommendations for this population.
