BMI and waist circumference (WC) are the two most common anthropometric measurements for general obesity and central obesity. The present study examined the distributions of BMI and WC and their relationship with blood pressure (BP) among college students in Shandong, China.
A total of 5838 college students (2915 men and 2923 women) aged 19-22 years participated in the study. Height, weight, WC, and BP of all participants were measured, and BMI and waist-to-height ratio were calculated. The BMI cutoffs recommended by the Working Group on Obesity in China were used to define underweight, normal weight, and overweight. Central obesity was defined as waist-to-height ratio of at least 0.5. High BP was defined as systolic blood pressure of at least 140 mmHg and/or diastolic blood pressure of at least 90 mmHg. All individuals were classified into four groups (Q1-Q4) according to the quartiles of BMI and WC, and the BP level, and the prevalence of high BP among the four groups was compared.
The prevalences of overweight, central obesity, and high BP were 22.74, 7.85, and 8.79% for men and 8.42, 3.02, and 1.92% for women, respectively; these figures were all significantly higher in men than in women (P<0.01). In both men and women, overweight and central obesity are associated with elevated BP.
College students with high BMI and high WC might have an increased risk of elevated BP. These findings emphasize the importance of the prevention of overweight and obesity to prevent future-related problems such as hypertension in young individuals.
体重指数（BMI）和腰围（WC）是用于评估一般肥胖和中心性肥胖的两种最常见人体测量指标。本研究调查了中国山东大学生的BMI和WC分布及其与血压（BP）的关系。
共有5838名年龄在19 - 22岁的大学生（2915名男性和2923名女性）参与了本研究。测量了所有参与者的身高、体重、WC和BP，并计算了BMI和腰高比。采用中国肥胖问题工作组推荐的BMI切点来定义体重过低、正常体重和超重。中心性肥胖定义为腰高比至少为0.5。高血压定义为收缩压至少140 mmHg和/或舒张压至少90 mmHg。所有个体根据BMI和WC的四分位数以及BP水平分为四组（Q1 - Q4），并比较四组中高血压的患病率。
男性超重、中心性肥胖和高血压的患病率分别为22.74%、7.85%和8.79%，女性分别为8.42%、3.02%和1.92%；这些数字在男性中均显著高于女性（P<0.01）。在男性和女性中，超重和中心性肥胖均与血压升高有关。
BMI和WC较高的大学生可能有血压升高的风险增加。这些发现强调了预防超重和肥胖对于预防年轻人未来相关问题如高血压的重要性。
