Despite the ongoing debate on the inconsistent and controversial effects of Tibetan diet on blood lipid levels at high altitude, this cross-sectional study was conducted to analyze the relationship between dietary practices and blood lipid levels among Jiarong Tibetan population. A total of 476 Jiarong Tibetan residents were included, in which basic demographic data, physical activity records, simplified food frequency questionnaire, and biochemical data were collected. Using multivariate logistic regression analysis, the potential associations between the variables were examined, and it was found that fat energy supply ratio increased with the elevation of altitude, while the lipid level showed an inverted U-shaped variation. However, the findings suggested that a diet rich in unsaturated fatty acids might balance the effects of the Tibetan diet on the risk of lipid metabolism disorders. Therefore, it is crucial to concentrate on the fat composition rather than the amount of fat E% intake on the plateau. The results highlighted the importance of investigating the interaction between environment and genes in lipid levels among plateau Tibetan population. However, further large-scale prospective studies are required for better understanding of the complexities involved in dietary practices and their influences on blood lipid levels.
尽管关于藏族饮食对高海拔地区血脂水平的影响存在不一致且有争议的效果仍在持续争论，但本横断面研究旨在分析嘉绒藏族人群饮食习惯与血脂水平之间的关系。共纳入476名嘉绒藏族居民，收集了基本人口统计学数据、身体活动记录、简化食物频率问卷和生化数据。采用多因素逻辑回归分析，检验变量之间的潜在关联，发现脂肪能量供应比例随海拔升高而增加，而血脂水平呈倒U形变化。然而，研究结果表明，富含不饱和脂肪酸的饮食可能平衡藏族饮食对脂质代谢紊乱风险的影响。因此，在高原地区关注脂肪组成而非脂肪能量百分比（E%）摄入量至关重要。结果强调了研究高原藏族人群血脂水平中环境与基因相互作用的重要性。然而，需要进一步开展大规模前瞻性研究，以更好地理解饮食习惯的复杂性及其对血脂水平的影响。
