From birth to adulthood in rural Ethiopia: the Butajira Birth Cohort of 1987.

Long-term birth cohorts from developing countries are uncommon. Here a unique birth to 18-years cohort based on all births during 1987 in a rural area of Ethiopia is presented. This was the first year of the ongoing Butajira Rural Health Programme, since when the sampled population has been followed up in regular household visits. A total of 1884 livebirths in 1987 formed the cohort, corresponding to a birth rate of 0.31 per woman per year; the male : female ratio was 1.10. Perinatal mortality was 22 per 1000 livebirths, and infant mortality 65 per 1000 livebirths. Survival from birth to 18 years was 760 per 1000. Living in Butajira town had a considerable survival advantage compared with the surrounding villages. Most deaths were due to infections. Four per cent of the cohort experienced the death of their mothers before the age of 18 years, and 15 of the girls delivered their own children, suggesting that 1 in 25 women may bear a child before their eighteenth birthday in this community. The children in the cohort received no consequent special care or attention, and so they probably accurately represent the harsh realities of growing up in rural Ethiopia at the turn of the Millennium. The huge gaps between their experience and that of their contemporaries in more affluent settings are a scandal of the 21st century.
