BACKGROUND
Hypertension in children and adolescents is on the rise worldwide, especially in China. The prevalence of hypertension is related to many factors, such as obesity. In the era of smart phones, it is important to study the negative health effects of mobile phones on blood pressure. The purpose of this study was to investigate the prevalence of hypertension and its association with smartphone addiction among junior school students in China.
METHODS
A school-based cross-sectional study was conducted, including total 2639 junior school students (1218 boys and 1421 girls), aged 12-15 years old (13.18 ± 0.93 years), enrolled in the study by random cluster sampling. Height, weight, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured following standard protocols, and the body mass index (BMI) was calculated. Overweight/obesity and hypertension were defined according to sex- and age-specific Chinese children reference data. The Smartphone Addiction Scale short version (SAS-SV) and the Pittsburgh Sleep Quality Index (PSQI) were used to assess smartphone addiction and sleep quality among the students, respectively. Multivariate logistic regression models were used to seek associations between smartphone addiction and hypertension.
RESULTS
The prevalence of hypertension and smartphone addiction among participants were 16.2% (13.1% for females and 18.9% for males) and 22.8% (22.3% for females and 23.2% for males), respectively. Obesity (OR = 4.028, 95% CI: 2.829-5.735), poor sleep quality (OR = 4.243, 95% CI: 2.429-7.411), smartphone addiction (OR = 2.205, 95% CI: 1.273-3.820) were significantly and independently associated with hypertension.
CONCLUSIONS
Among the junior school students surveyed in China, the prevalence of hypertension was high, which was related to obesity, poor sleep quality and smartphone addiction. These results suggested that smartphone addiction may be a new risk factor for high blood pressure in adolescents.
背景
儿童和青少年高血压在全球范围内呈上升趋势，尤其是在中国。高血压的患病率与肥胖等许多因素有关。在智能手机时代，研究手机对血压的不良健康影响很重要。本研究旨在调查中国初中生高血压的患病率及其与智能手机成瘾的关系。
方法
采用整群随机抽样方法，对 2639 名 12-15 岁（13.18±0.93 岁）的初中生进行了一项基于学校的横断面研究。按照标准方案测量身高、体重、收缩压（SBP）和舒张压（DBP），计算体重指数（BMI）。根据性别和年龄特异性中国儿童参考数据，定义超重/肥胖和高血压。使用智能手机成瘾量表短版（SAS-SV）和匹兹堡睡眠质量指数（PSQI）分别评估学生的智能手机成瘾和睡眠质量。采用多变量 logistic 回归模型探讨智能手机成瘾与高血压之间的关系。
结果
参与者中高血压和智能手机成瘾的患病率分别为 16.2%（女生为 13.1%，男生为 18.9%）和 22.8%（女生为 22.3%，男生为 23.2%）。肥胖（OR=4.028，95%CI：2.829-5.735）、睡眠质量差（OR=4.243，95%CI：2.429-7.411）、智能手机成瘾（OR=2.205，95%CI：1.273-3.820）与高血压显著相关。
结论
在中国被调查的初中生中，高血压的患病率较高，与肥胖、睡眠质量差和智能手机成瘾有关。这些结果表明，智能手机成瘾可能是青少年高血压的一个新的危险因素。
