There may be sex differences in BMI and blood pressure levels in school-age children, especially in the face of lifestyle changes. This study aimed to explore sex differences in changes in BMI and blood pressure in Chinese school-aged children during the COVID-19 quarantine. The cohort study of 445 school-aged children examined the change of BMI and blood pressure during the five-month quarantine. Multivariable Cox regression models were created to identify potential predictors of overweight, obesity, and elevated blood pressure (EBP). During the COVID-19 quarantine, the proportion of boys with overweight and obesity increased (P = 0.036), and the proportion of both boys and girls with Pre-EBP and EBP increased (P = 0.004 in boys; P < 0.001 in girls). The multivariate Cox regression analysis demonstrated that the setting, eating chili, parents' perception of their child's size and family doting were associated with overweight, obesity, and EBP. The study showed that BMI was more likely to increase in boys, and blood pressure increased in both boys and girls during the COVID-19 quarantine.
在儿童期，尤其是在生活方式改变的情况下，BMI 和血压水平可能存在性别差异。本研究旨在探讨 COVID-19 隔离期间中国学龄儿童 BMI 和血压变化的性别差异。这项队列研究对 445 名学龄儿童进行了研究，观察了五个月隔离期间 BMI 和血压的变化。建立多变量 Cox 回归模型，以确定超重、肥胖和高血压（EBP）的潜在预测因素。在 COVID-19 隔离期间，超重和肥胖男孩的比例增加（P=0.036），且男孩和女孩的 Pre-EBP 和 EBP 比例均增加（男孩 P=0.004；女孩 P<0.001）。多变量 Cox 回归分析表明，环境、吃辣、父母对孩子体型的认知和家庭溺爱与超重、肥胖和 EBP 有关。研究表明，在 COVID-19 隔离期间，男孩的 BMI 更有可能增加，男孩和女孩的血压均升高。
