Previous studies of nutrition among nomadic pastoralists in South Turkana, Kenya, have suggested that social mechanisms may be used to buffer vulnerable members of the group from acute nutritional stress. During 1989-1990, 24-hour dietary recall data were collected from 101 lactating women in Ngisonyoka, Turkana. Multivariate regression was then used to quantify the effects of environmental, socioeconomic, and demographic variables on dietary intake. The location of individual herding camps had the greatest impact on maternal diet. After the site of camps, rainfall patterns, the socioeconomic ranking of the herding unit, and the age and rank of wives were the most significant predictors of maternal food consumption. The results suggest that some women in the study were buffered from moderate seasonal nutritional stress by the practice of food-sharing among members of their social network, as well as by voluntary reduction in dietary intake by other women. Maternal dietary intake differed both qualitatively and quantitatively between herding camps of higher and lower socioeconomic ranking. © 1994 Wiley-Liss, Inc.
此前对肯尼亚南图尔卡纳游牧牧民营养状况的研究表明，社会机制可能被用来保护群体中的弱势群体免受急性营养压力。1989年至1990年期间，从图尔卡纳的恩吉索尼奥卡的101名哺乳期妇女那里收集了24小时饮食回忆数据。然后使用多元回归来量化环境、社会经济和人口变量对饮食摄入量的影响。各个放牧营地的位置对孕产妇饮食影响最大。除了营地位置外，降雨模式、放牧单位的社会经济排名以及妻子的年龄和排名是孕产妇食物消费的最重要预测因素。结果表明，研究中的一些妇女通过其社交网络成员之间的食物分享做法，以及其他妇女自愿减少饮食摄入量，从而免受中度季节性营养压力的影响。社会经济排名较高和较低的放牧营地之间，孕产妇的饮食摄入量在质量和数量上都有所不同。© 1994威利 - 利斯公司。
