Sahel nutrition survey, 1974

Area of Science:

• Public Health
• Nutrition Science
• Pediatrics

Background:

• Accurate nutrition status assessment is crucial during food shortages for effective aid distribution and impact evaluation.
• Child undernutrition poses significant public health challenges in developing nations, requiring timely and reliable surveillance methods.

Purpose of the Study:

• To assess the prevalence of severe and acute undernutrition in young children in several West African nations during a period of food shortage.
• To evaluate the utility of the weight-for-height index as a rapid assessment tool for child undernutrition.

Main Methods:

• A population proportional sampling method was employed to select participants.
• The weight-for-height index was used as the criterion for assessing nutritional status, being relatively independent of sex, race, and age.
• The study focused on children aged approximately 6 months to 6 years in Mali, Mauritania, Niger, Upper Volta, and Chad.

Main Results:

• Approximately 10% of the sampled children in Mali, Mauritania, Niger, and Upper Volta were found to be severely and acutely undernourished.
• Over 20% of the sampled children in Chad exhibited severe and acute undernutrition.
• The study observed that younger children were initially affected, with older children's undernutrition prevalence increasing as the food shortage intensified.

Conclusions:

• The weight-for-height index proved to be a reliable and effective tool for the rapid assessment of acute undernutrition in children during a food shortage.
• This nutrition surveillance method is a fundamental tool for developing nations requiring prompt evaluation of child nutritional status in crisis situations.
• The findings underscore the critical need for targeted nutritional interventions in the studied regions.
