      Between 1 February 1987 and 31 May 1988 an evaluation of a nutritional rehabilitation centre in Tahoua, Niger was conducted. Among the 381 children admitted to the centre, 61 (16%) had kwashiorkor and 347 (91.3%) were aged between 6 and 29 months. Recovery and death rates were 46.2% and 14.4%, respectively. The median duration of stay until recovery was 21 days. Sixty-two per cent of deaths occurred during the 1st week of hospitalization. Three risk factors for death were identified by the study: patients with kwashiorkor with a weight/height (W/H) less than -3 SD, those with marasmus with a W/H less than -5 SD, and those dehydrated with marasmus. Among children included in the follow-up study after leaving the centre, the risk of dying during the follow-up period among children who absconded was 7.1 times higher than the risk observed among children who recovered. Among the children who recovered, no relapse was observed 3-18 months after they left the centre. This investigation indicates the importance of intensive therapeutic feeding centres in areas with a high prevalence of malnutrition.
    • Estimates of the duration of untreated acute malnutrition in children from Niger.

      Expected incidence of acute malnutrition is the most appropriate measure for projecting the needs of a nutritional treatment program over time in terms of staffing, food, and other treatments, but direct estimation of incidence is rarely feasible at the onset of an intervention. While incidence may be approximated as prevalence/average duration, ethical constraints preclude measurement of the duration of acute malnutrition in the absence of treatment. The authors used a compartmental model to estimate the duration of untreated moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) in children aged 6-60 months. The model was informed by data from a community-based cohort of children in Niger followed from August 2006 to March 2007. Maximum likelihood estimates for the duration of untreated MAM, defined by weight-for-height z score and middle upper arm circumference, were 75-81 days and 101-116 days, respectively. The duration of untreated SAM, defined by weight-for-height z score, was 45 days. The duration of untreated MAM appears to have been shorter among children aged 6-35 months compared with those aged 36-60 months. Such estimates of the duration, and thus incidence, of untreated malnutrition can be used to improve projections of program needs and estimates of the global burden of acute malnutrition.
