Several studies have documented a positive association between waist circumference (WC) and risk factors for chronic disease in children and adolescents. The present study examined the relationship of WC distribution to BP levels and prevalence of relatively high BP among children and adolescents in Shandong, China.
A total of 6895 students (3442 boys and 3453 girls) aged 7-17 years participated in this study. Height, weight, WC and BP of all subjects were measured; body mass index (BMI) and waist-to-height ratio (WHtR) were calculated from their height, weight and WC. Relatively high BP status was defined as systolic blood pressure (SBP) and/or diastolic blood pressure (DBP)≥ 95th percentile for age and gender.
SBP and DBP were positively correlated with WC, WHtR and BMI in both boys and girls. The strongest correlation observed for BP was with WC. Z-scores of BP and the prevalence of relatively high BP increased with WC percentiles, this trend being especially obvious in the upper percentiles of WC. The prevalence of relatively high BP increased from 9.21% (boys) and 11.76% (girls) in the <5th WC percentile group to 58.99% (boys) and 40.34% (girls) in the ≥ 95th WC percentile group, an increase of 5.4- and 2.4-times.
Children and adolescents with elevated WC might have an increased risk of hypertension. These findings emphasize the importance of the prevention of overweight and obesity in order to prevent future-related problems such as hypertension in children and adolescents.
多项研究记录了腰围（WC）与儿童和青少年慢性病危险因素之间的正相关关系。本研究在中国山东调查了 WC 分布与儿童和青少年血压水平及相对较高血压患病率的关系。
共有 6895 名学生（男 3442 名，女 3453 名）年龄在 7-17 岁之间参与了这项研究。所有受试者的身高、体重、WC 和血压均进行了测量；体重指数（BMI）和腰围身高比（WHtR）根据身高、体重和 WC 进行计算。相对较高的血压状态定义为收缩压（SBP）和/或舒张压（DBP）≥年龄和性别第 95 百分位。
SBP 和 DBP 与男孩和女孩的 WC、WHtR 和 BMI 呈正相关。BP 与 WC 的相关性最强。BP 的 Z 评分和相对较高的 BP 患病率随着 WC 百分位数的增加而增加，这种趋势在 WC 的较高百分位数中尤为明显。相对较高的 BP 患病率从<5th WC 百分位组的 9.21%（男孩）和 11.76%（女孩）增加到≥95th WC 百分位组的 58.99%（男孩）和 40.34%（女孩），增加了 5.4-和 2.4 倍。
WC 升高的儿童和青少年可能患高血压的风险增加。这些发现强调了预防超重和肥胖的重要性，以预防儿童和青少年未来相关问题如高血压的发生。
