不同膳食行为因素对成年人血甘油三酯水平影响的横断面研究

Influence of diet and behavior related factors on the peripheral blood triglyceride levels in adults： a cross-sectional study

目的 分析不同膳食行为因素对成年人血TG水平影响。方法 利用2010年浙江省居民代谢综合征流行病学调查资料，纳入无主要慢性病病史的调查对象13 434人，采用广义线性模型估计相关膳食行为影响因素的作用。结果 样本人群血TG均值为（1.36±1.18） mmol/L，TG测定值升高和边缘值升高的比例分别为10.3%和11.0%，其中男性升高和边缘升高的比例分别为11.9%和11.7%，均高于女性的8.8%和10.3%，差异有统计学意义（χ2=44.135，P〈0.001）。样本人群食用油超过推荐量一半以上，而水果、奶制品和坚果摄入量以及体育锻炼则远低于推荐量；男性是否吸烟、是否饮酒以及不同畜禽肉、水果和饮水摄入情况之间，女性不同水产品摄入量和体育锻炼情况之间的差异有统计学意义。在调整其他因素后，年龄、饮酒、主食和水产品摄入量增加血TG水平，摄入奶制品可降低血TG水平；交互作用分析发现男性水果和畜禽肉摄入量以及女性主食摄入量对血TG水平存在交互作用。结论 高甘油三酯血症是浙江省居民一种主要的代谢异常，在社区干预中应将饮酒、主食和肉类（畜禽肉和水产品）摄入量作为优先考虑因素。

Objective To study the influence of diet and behavior related factors on the peripheral blood triglyceride levels in adults, through a cross-sectional survey.Methods The current study included 13 434 subjects without histories of major chronic diseases from a population-based cross-sectional survey：the 2010 Metabolic Syndrome Survey in Zhejiang Province. A generalized linear model was used to investigate the influence of diet/behavior-related factors on the peripheral blood triglyceride levels.Results Mean TG of the sample population appeared as （1.36±1.18） mmol/L. The proportions of elevated TG and marginally elevated TG were 10.3% and 11.0% respectively, with statistically significant difference seen between males and females （χ2=44.135, P〈0.001）. In this sampled population, the daily intake of cooking oil was exceeding the recommendation levels by over 50% while the intake of fruit, milk, nuts and physical exercise were much below the recommendation. There were statistically significant differences between smoking, alcohol-intake, meat, fruit and water intake in male population from this study. However, in females, the intake of aquatic product and physical exercise showed statistically significant differences. After controlling for other variables, factors as age, drinking, staple food and aquatic products showed positive influence on TG, while milk presented negative influence on TG. Through interaction analysis, fruit and meat intake in males and staple food in females showed positive influence on TG, when compared to the reference group.Conclusion Hyperglyceridemia appeared as one of the major metabolic abnormities in Zhejiang province. Programs on monitoring the alcohol, staple food and meat intake should be priority on intervention, in the communities.
