Social and environmental factors associated with diarrhoea and growth in young children: Child health in urban Africa

This study investigates the relationship between social and environmental variables and diarrhoea and growth in children aged between 6 and 36 months in an urban area of The Gambia, West Africa. The social and environmental conditions of 493 children were observed and recorded over a period of 12 months. Two hundred and seventy-seven children were under weekly diarrhoea surveillance for a 15 week period during the wet season and 322 children had anthropometric measurements taken in May and September. Computer analysis was used to determine association between single and multiple environmental and social factors and diarrhoea prevalence and growth. The results of the diarrhoea surveillance showed that there was considerable variation between individual children. Thirty children had no diarrhoea during the period of surveillance and 30 had diarrhoea for over 24% of the time, with 2 children having diarrhoea for more than 50 days out of a total of 105. None of the social and environmental variables recorded showed a significant relationship with diarrhoea prevalence. The anthropometric measurements showed that at the end of the wet season, in September, 23% of children in this age group were less than 90% of the National Centre for Health Statistics standards of height for age and several of the variables recorded showed a statistically significant association with this measurement.
