背景资料：几项研究表明，坦桑尼亚的游牧民族马赛人，尽管饮食中饱和脂肪含量很高，但冠心病的发病率很低。也有人认为它们可能受到基因保护。最近的研究详细介绍了其他潜在的保护因素，但是，lacking.Methods：985坦桑尼亚男性和女性（130马赛，371农村班图人和484城市班图人）的横断面调查，平均年龄为46（9.3）岁。人体测量的措施，血压，血脂，和报告的饮食模式和体力活动水平进行了assessed.Results：82%的马赛主题报告了高脂肪/低碳水化合物的摄入量，而77%的农村班图主题报告了低脂肪/高碳水化合物的摄入量，而高脂肪/高碳水化合物的摄入量是主要的饮食模式的城市班图组，报告的55%。马赛人最明显的发现是能量消耗极高，相当于每天超过基本需要量2 565千卡，而农村地区为1 500千卡，城市班图人为891千卡。马赛人的平均体重指数低于农村和城市班图人。马赛人的平均收缩压也低于农村和城市班图人。马赛揭示了一个有利的lipidprofile.Conclusion：潜在的致动脉粥样硬化的饮食之间的马赛人没有反映在血脂和抵消可能是非常高的能量消耗水平和低体重。
Background: Several studies have revealed that the Masai, pastoralists in Tanzania, have low rates of coronary heart disease despite a diet high in saturated fat. It has also been suggested that they may be genetically protected. Recent studies detailing other potential protective factors, however, are lacking.Methods: A cross-sectional investigation of 985 Tanzanian men and women (130 Masai, 371 rural Bantu and 484 urban Bantu) with mean age of 46 (9.3) years. Anthropometric measures, blood pressure, serum lipids, and the reported dietary pattern and physical activity level were assessed.Results: 82% of Masai subjects reported a high fat/low carbohydrate intake, whereas 77% of the rural Bantu subjects reported a low fat/high carbohydrate intake, while a high fat/high carbohydrate intake was the main dietary pattern of the urban Bantu group as, reported by 55%. The most conspicuous finding for the Masai was the extremely high energy expenditure, corresponding to 2565 kcal/day over basal requirements, compared with 1500 kcal/day in the rural and 891 kcal/day for the urban Bantu. Mean body mass index among the Masai was lower than the rural and urban Bantu. Mean systolic blood pressure of the Masai was also lower compared with their rural and urban Bantu counterparts. The Masai revealed a favourable lipid profile.Conclusion: The potentially atherogenic diet among the Masai was not reflected in serum lipids and was offset probably by very high energy expenditure levels and low body weight.
