Incidence of low birth weight in three selected communities of Bangladesh.

This prospective study was conducted in urban affluent, slum and rural communities of Bangladesh during Feb '94 to Feb '95. From each community, 250 pregnant mothers were recruited in the study and at the end total 660 live births were studied to determine the incidence and risk factors of low birth weight. Incidence of low birth weight was highest in urban slum (36.8%) followed by rural area (20.9%) and lowest in urban affluent community (18.3%). The area of residence had a significant influence on birth weight suggesting that environmental stress had detrimental effect on birth weight. Age, weight and height of mothers were also risk factor for low birth weight of their babies. Mothers of less than 20 years and more than 35 years, weighing less than 40 kg and having height less than 140 cm had the higher risk of giving birth to low birth weight babies. Incidence of low birth weight was highest (73.2%) among the primigravidae mothers and 36.8% among the mothers who had no antenatal check-up, but it was 15.9% among those who had check-up more than 7 times. The distribution of low birth weight babies was higher (48.2%) among the mothers who had never gone to school. To reduce the incidence of low birth weight, upliftment of socio-economic condition has got no alternative which is very much related to education level of the people. Emphasis should be given on mothers' education which is one of the influencing factors of birth weight of babies.
