The study is a three-year longitudinal survey investigating the determinants and consequences of protein-energy malnutrition in a rural African population.
Baseline censuses were conducted betweeen December 1986 and June 1987 to identify, inform and measure all households living within the selected villages. The census surveyed about 3,300 households. Information regarding socioeconomic conditions and child anthropometry was updated one year later, and every 6 months thereafter.
They also conducted monthly visits to all pregnant women in the sample between the time of the baseline census and December 1988 (sample size: 940 women). Monthly visits included assessments of anthropometry, morbidity, use and cost of health services, child care and feeding, household income and expenditures, recall of 24-hour household food consumption, disaggregated agricultural labour use, and agricultural production.
Information is collected at individual, household and community level. The study also records food prices, rainfall, and changes in the source of drinking water supply. Initial sample size: 3,300 households. Endline sample size: 2,200 households. 940 households with pregnant women were visited monthly.
