Abstract

Dietary pattern is quite distinct among the inhabitants of high-altitude areas because of environmental and geographical uniqueness; hence, it is important to investigate this data as accurately as possible. However, very few data are related to these populations up to now. Based on the food frequency questionnaire (FFQ) used in the Chinese population, a revised Tibetan edition was developed with respect to the lifestyle in high-altitude areas. After assessment of validity and reproducibility, a nutrition intake survey was conducted among 1,071 randomly sampled Tibetan people. In addition, the Bland-Altman approach was used to compare the agreement between the two dietary tools. For the reproducibility analysis, intraclass correlation coefficients (ICC) were calculated to examine the agreement of food groups and nutrients from the two FFQs (FFQ1 and FFQ2). Nutrient intake was calculated using food composition tables. For the validity analysis, Pearson's correlation of food groups intakes varied from 0.22 to 0.91 (unadjusted). The correlations of nutrients ranged from 0.24 to 0.76 (unadjusted). In the analysis of reliability, the ICC of food groups varied from 0.27 to 0.70 (unadjusted). The ICC of nutrient intakes ranged from 0.22 to 0.87 (unadjusted). The results of nutritional analysis showed that ~25% of foods consumed frequently were traditional Tibetan foods. However, traditional Han foods were frequently consumed. In addition, the energy, iron, and protein intakes for male or female subjects were close to the Chinese Dietary Nutrient Reference Intake (Chinese DRIs); however, fat and sodium intakes were significantly higher than the Chinese DRIs. Interestingly, lower intakes of other types of nutrition, such as vitamin C were detected in people living in high-altitude areas. Our data indicated that excess consumption of fat and sodium and insufficient intake of vitamin C were common among Tibetan people, as compared with the most Chinese people living in the plateau areas. More investigations are needed to reveal the association between the food intake style and high-altitude endemic diseases.

摘要

由于环境和地理的独特性,高海拔地区居民的饮食模式差异很大;因此,尽可能准确地调查这些数据非常重要。然而,到目前为止,与这些人群相关的数据非常少。基于中国人群使用的食物频率问卷(FFQ),针对高海拔地区的生活方式开发了修订版的藏文版。在评估有效性和可重复性之后,对1071名随机抽样的藏族人进行了营养摄入调查。此外,采用Bland-Altman方法比较两种饮食工具之间的一致性。对于可重复性分析,计算组内相关系数(ICC)以检验两个FFQ(FFQ1和FFQ2)中食物组和营养素的一致性。使用食物成分表计算营养素摄入量。对于有效性分析,食物组摄入量的Pearson相关性在0.22至0.91之间(未调整)。营养素的相关性在0.24至0.76之间(未调整)。在可靠性分析中,食物组的ICC在0.27至0.70之间(未调整)。营养素摄入量的ICC在0.22至0.87之间(未调整)。营养分析结果表明,经常食用的食物中约25%是传统藏式食物。然而,传统汉族食物也经常被食用。此外,男性或女性受试者的能量、铁和蛋白质摄入量接近中国膳食营养素参考摄入量(中国DRIs);然而,脂肪和钠的摄入量明显高于中国DRIs。有趣的是,在高海拔地区生活的人群中检测到其他类型营养素的摄入量较低,如维生素C。我们的数据表明,与大多数生活在高原地区的中国人相比,藏族人普遍存在脂肪和钠摄入过量以及维生素C摄入不足的情况。需要更多的调查来揭示食物摄入方式与高海拔地区地方病之间的关联。
