The birthweight is the most important determinant of mortality and morbidity in the neonatal period and may have an influence on health in adult life.
The high rate of low birthweight in developing countries is therefore a major health problem.
Maternal malnutrition is usually assumed to be a causal factor but other environmental factors are also involved.
In this study we analysed maternal nutritional and socio-economic factors as determinants of birthweight in term infants from a rural African society characterised by a high rate of chronic malnutrition.
Relations of maternal weight, gestational weight gain, parity, socio-economic status and infant sex with birthweight were analysed in 1 477 women and child pairs.
The selected women were followed from early pregnancy and had an uncomplicated delivery at term of a living singleton child.
The gestational weight gain was 5.6 (SD 6.0) kg and the mean birthweight 2.933 kg (SD 408).
Maternal weight, representing the maternal long-term nutritional situation, was the most important independent determinant of birthweight, accounting for 13.0% of the variance in birthweight.
The weight gain, representing the short-term nutritional situation, explained only 5.6% of the variance.
Birthweight increased by 20 g (CI 18-23) for each kg maternal weight and by 15 g (CI 12-18) for each kg gestational weight gained. (...)
