摘要
目的分析1991～2011年我国9省区成年居民膳食胆固醇摄入分布的变化趋势及不同分位点人口经济因素对分布变化的影响。方法以纵向研究“中国健康与营养调查”在1991～2011年间至少参加过两轮调查的13685名18～65岁成年人（男性49．6％）为对象，采用偏度均值变异系数（LMS）法分析胆固醇摄入分布的变化趋势，利用纵向分位数回归法研究人口经济因素对不同百分位胆固醇摄入变化的影响。结果1991～2011年我国9省区成年男性和女性膳食胆固醇摄入分布峰值下降，曲线右移变宽，但分布变化的幅度不均匀，1991～2000年变化幅度最显著。不同分位点胆固醇摄入量均随时间呈增加趋势，高分位点增幅较大，不同分位点胆固醇摄入与城市化、收入和受教育水平呈显著的正相关关系。结论过去二十余年，我国9省区18～65岁成年居民膳食胆固醇摄入量呈增加趋势，高分位点胆固醇摄入增幅更大。城市化程度较高的社区、高收入水平、高分位点胆固醇摄入水平的成年人应是干预的重点地区或人群。
Objective To examine the changes in dietary cholesterol intake and related risk factors among Chinese adults aged lg to 65 from 1991 to 2011. Methods Data were collected from the China Health and Nutrition Survey （CHNS）, a prospective, open cohort study. A total of 55 794 observations from 13 685 apparently healthy Chinese adults aged 18-65 y （the proportion of male was 49.6 %） at entry from 1991 to 2011 were analyzed. The coefficient of skewness-median- coefficient of variation （LMS） method was used to the evaluate the changes in dietary cholesterol distribution over time. Longitudinal quantile regression was performed to analyze the influence of socio-demographic factors on different levels of dietary cholesterol intake. Results From 1991 to 2011, a downward and rightward shift in the entire distribution of dietary cholesterol intake was shown and indicated increasing proportion of adults with higher cholesterol intake in both men and women. The most dramatic shift occurred between 199 l and 2000. All selected quantiles of dietary cholesterol intake showed increased trend over time and higher quantile level showed much bigger increase. Positive association was observed between urbanicity, income and education and dietary cholesterol intake. Conclusion A rapid increase in dietary cholesterol intake was present among Chinese adults from 1991 to 2011, especially much bigger increase in higher quantile. It should be priority to take interventions among adults with higher percentile dietary cholesterol, higher income, or living in highly urbanized communities.
