The International Obesity Task Force recently developed an extended body mass index (BMI) cut-offs for screening thinness, overweight and obesity among children and adolescents. The present study examined the profiles of blood pressure (BP) among children and adolescents with different BMI categories in Shandong, China.
Data for this study were obtained from a large cross-sectional survey of schoolchildren. A total of 44,630 students (22,404 boys and 22,226 girls) aged 7-18 years participated in this study. The grades of body weight (thinness grade 1-3, normal weight, overweight and obesity grade 1-3) was defined by the international BMI cut-offs. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured on one occasion. High BP was defined as SBP and/or DBP ≥95th percentile for age and gender.
The overall prevalence of thinness (grade 1-3), overweight and obesity (grade 1-3) were 7.80, 18.74 and 8.56% for boys and 11.16, 13.53 and 3.70% for girls, respectively, boys had a lower prevalence of thinness and higher prevalence of overweight and obesity than girls (p < .01). Urban boys and girls had a lower prevalence of thinness and higher prevalence of overweight and obesity than their rural counterparts (p < .01). Children and adolescents with high BMI had a higher BP levels than their counterparts with normal and low BMI.
High BMI is strongly related to elevated BP. Our findings emphasize the importance of the prevention of overweight/obesity to prevent future-related problems such as hypertension in children and adolescents.
国际肥胖特别工作组最近制定了扩展的身体质量指数（BMI）临界值，用于筛查儿童和青少年的消瘦、超重和肥胖情况。本研究调查了中国山东不同BMI类别的儿童和青少年的血压情况。
本研究数据来自对学童的大规模横断面调查。共有44630名7至18岁的学生（22404名男生和22226名女生）参与了本研究。体重等级（消瘦1 - 3级、正常体重、超重和肥胖1 - 3级）根据国际BMI临界值定义。一次性测量收缩压（SBP）和舒张压（DBP）。高血压定义为SBP和/或DBP≥年龄和性别的第95百分位数。
男生消瘦（1 - 3级）、超重和肥胖（1 - 3级）的总体患病率分别为7.80%、18.74%和8.56%，女生分别为11.16%、13.53%和3.70%，男生的消瘦患病率低于女生，超重和肥胖患病率高于女生（p < 0.01）。城市男生和女生的消瘦患病率低于农村同龄人，超重和肥胖患病率高于农村同龄人（p < 0.01）。BMI高的儿童和青少年的血压水平高于BMI正常和低的同龄人。
高BMI与血压升高密切相关。我们的研究结果强调了预防超重/肥胖对于预防儿童和青少年未来相关问题（如高血压）的重要性。
