Demographic data for the recruited individuals.

BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TC, total cholesterol; TG, triglyceride. Age, SBP, DBP, TC, TG, LDL-C and HDL-C (expressed as mean ± standard deviation) were not normally distributed and were analyzed by the Mann-Whitney U-test. BMI (expressed as mean ± standard deviation) was normally distributed and was analyzed by Student’s t-test. Other data are expressed as frequencies and percentages and were evaluated by the χ2-test.

BMI，即身体质量指数（Body Mass Index）；SBP，即收缩压（systolic blood pressure）；DBP，即舒张压（diastolic blood pressure）；HDL-C，即高密度脂蛋白胆固醇（high-density lipoprotein cholesterol）；LDL-C，即低密度脂蛋白胆固醇（low-density lipoprotein cholesterol）；TC，即总胆固醇（total cholesterol）；TG，即甘油三酯（triglyceride）。年龄、收缩压、舒张压、总胆固醇、甘油三酯、低密度脂蛋白胆固醇及高密度脂蛋白胆固醇（以均值±标准差表示）不符合正态分布，故采用曼-惠特尼U检验（Mann-Whitney U-test）进行统计分析。身体质量指数（以均值±标准差表示）符合正态分布，采用学生t检验（Student’s t-test）进行分析。其余数据以频数及百分比表示，通过卡方检验（χ²-test）进行评估。
