AbstractLittle is known about birth or mortality rates of twins in The Gambia. There are no reports of the causes of death among twins in sub-Saharan Africa. We identified twin births and deaths from a community-based study which had been carried out in a large rural region of The Gambia over a 5-year period from 1989 to 1993. The overall twinning rate excluding stillbirths was 14.3 (95% CI 12.9, 15.8) per 1000 live deliveries. This was significantly lower among the Mandinka ethnic group (8.8 per 1000) than among the Serahulis (15.1 per 1000) or Fulas (18.3 per 1000). The early-neonatal, late-neonatal and post-neonatal twin mortality rates were 114.0, 45.9 and 64.2 per 1000 live twin births, respectively. In comparison, the early-neonatal, late-neonatal and post-neonatal mortality rates of singletons were 18.6, 16.0 and 41.1 per 1000, respectively. In the post-neonatal period, malnutrition was more frequently a cause of death among twins than among singletons (7.8 per 1000 twin births vs 2.0 per 1000 singleton births; p = 0.0008). Appropriate strategies for preventing malnutrition are required for this high-risk group.
