Abstract
The nutrition status of Samburu tribesmen of northern Kenya and the potential nutritional effects of a food-for-work programme were assessed by anthropometric and dietary surveys over a period of five weeks. The investigations were carried out at four input localities, where the programme had provided a daily average of 173 kcal and 5 g protein per capita over the preceding year, and a fifth control area.
Compared with Kenya as a whole, the Samburu community showed an unexpectedly high prevalence of wasting: 74% of the surveyed individuals were below 90% of the NCHS weight-for-height median, and 34% were below 80%. Relative wasting was especially prevalent among school-age children, of whom 86% were below 90% and 44% were below 80% of the standard, and among elders, with 88% and 64% below these thresholds respectively. Mid-upper arm circumferences were lowest among school-age children (mean 14.6 cm). Haematocrits were low in all age and social groups. Aside from three preschool children with xerophthalmia, a number of both preschool and school-age children had clinical histories suggestive of earlier vitamin A deficiency. Goitre was more prevalent among the older generations than among school-age or preschool children, suggesting a periodic but not uninterrupted availability of iodized salt. In the input locations, both anthropometric and haematocrit values among the most vulnerable members of the communities, preschool children and women of reproductive age, were significantly higher than those for comparable groups in the control location. Overall, the food-for-work programme was judged to be a worthwhile effort to help Samburus to be once again self-sufficient.
