Waist-to-height ratio (WHtR) is proposed as a simple and effective screening tool for abdominal obesity and cardiovascular disease risk factors. The present study examined the profiles of blood pressure (BP) among children and adolescents categorized by WHtR cutoffs.
A total of 28 074 (14 015 boys and 14 059 girls) students aged 7-17 years participated in the study. Height, waist circumference and BP of all patients were measured, and WHtR was calculated. Relatively high blood pressure (RHBP) status was defined as systolic BP and/or diastolic BP of at least the 95th percentile for age and sex. All patients were divided into three groups (low, moderate and high) according to their WHtR. BP level and the prevalence of RHBP among the three groups were compared.
In both boys and girls, significant differences in BP level and the prevalence of RHBP were observed among the three groups (P<0.01). Children and adolescents aged 7-17 years in the 'high WHtR group' (≥0.5) had higher systolic BP and diastolic BP compared with those in the 'low WHtR group' (<0.4) by 6.07-11.49 and 3.28-6.34 mmHg for boys and 5.62-9.76 and 3.14-5.95 mmHg for girls; the 'high WHtR group' had the highest (34.02% for boys and 30.87% for girls) and the 'low WHtR group' had the lowest prevalence of RHBP (15.23% for boys and 12.53% for girls).
High WHtR is associated with elevated BP. These findings emphasize the importance of the prevention of abdominal obesity to prevent future problems such as hypertension in children and adolescents.
腰高比（WHtR）被提议作为一种用于筛查腹型肥胖和心血管疾病风险因素的简单有效的工具。本研究调查了根据WHtR临界值分类的儿童和青少年的血压情况。
共有28074名7至17岁的学生（14015名男孩和14059名女孩）参与了本研究。测量了所有患者的身高、腰围和血压，并计算了WHtR。相对高血压（RHBP）状态定义为收缩压和/或舒张压至少处于年龄和性别的第95百分位数。所有患者根据其WHtR分为三组（低、中、高）。比较了三组的血压水平和RHBP患病率。
在男孩和女孩中，三组之间的血压水平和RHBP患病率均存在显著差异（P<0.01）。“高WHtR组”（≥0.5）中7至17岁的儿童和青少年，其收缩压和舒张压高于“低WHtR组”（<0.4），男孩分别高6.07 - 11.49 mmHg和3.28 - 6.34 mmHg，女孩分别高5.62 - 9.76 mmHg和3.14 - 5.95 mmHg；“高WHtR组”的RHBP患病率最高（男孩为34.02%，女孩为30.87%），“低WHtR组”的RHBP患病率最低（男孩为15.23%，女孩为12.53%）。
高WHtR与血压升高有关。这些发现强调了预防儿童和青少年腹型肥胖以预防未来诸如高血压等问题的重要性。
