Objective. The present study aimed to compare two situations of endemic malnutrition among <5-year-old African children and to estimate the incidence, the duration and the case fatality of severe wasting episodes Design Secondary analysis of longitudinal studies, conducted several years ago, which allowed incidence and duration to be calculated from transition rates. The first site was Niakhar in Senegal, an area under demographic surveillance, where we followed a cohort of children in 1983-5. The second site was Bwamanda in the Democratic Republic of Congo, where we followed a cohort of children in 1989-92. Both studies enrolled about 5000 children, who were followed by routine visits and systematic anthropometric assessment, every 6 months in the first case and every 3 months in the second case. Results Niakhar had less stunting, more wasting and higher death rates than Bwamanda Differences in cause-specific mortality included more diseases, more marasmus, but less malaria and severe anaema in Niakhar Severe wasting had a higher incidence, a higher prevalence and a more marked age profile in Niakhar. However, despite the difference, the estimated mean durations of episodes of severe wasting, calculated by multi-state life table, were similar in the two studied (7.5 months) Noteworthy were the differences in the prevalance and incidence of severe wasting depending on the anthropometric indicator (weight-for-height Z-score <=-3.0 or mid upper-arm circumference <110mm) and the reference system (National Center for Health Statistics 1977, Centers for Disease Control and Prevention 2000 or Multicentre Growth Reference Study 2006) Conclusions. Severe wasting appeared as one of the leading cause of death among under-fives it had a high incidence (about 2% per child-semester), long duration of episodes and high case fatality rates (6 to 12%)
