摘要:
目的 探讨新冠疫情防控下体检人群生活方式及健康状况的相关危险因素,为疫情常态化下人群健康干预提供理论依据。 方法 采用方便取样法,对2021年6—7月于北京大学第一医院体检中心进行健康体检的人员进行问卷调查,使用描述性分析及多元线性回归分析方法,探讨疫情暴发前后人群体重与生活方式变化的关系。 结果 共纳入392名研究对象,男女比例0. 8∶ 1,年龄为(38.89±12.45)岁,体检人群疫情暴发后体重较前增长(0.84±3.24)kg(t=5.135, P < 0.001)。根据性别、年龄层、职业、学历、婚姻状态、BMI分层等进行分组,结果显示女性(t=4.361, P < 0.001)、青年人群(t=4.660, P < 0.001)、消瘦人群(t=5.231, P < 0.001)、正常体重人群(t=4.378, P < 0.001)、已婚人群(t=4.221, P < 0.001)、职工(t=5.252, P < 0.001)、学历为大学本科人群(t=3.944, P < 0.001)体重增加。多元线性回归分析显示零食摄入量(B=0.440, P=0.015)、谷类摄入量(B=0.830, P=0.001)和起床时间(B=0.430, P=0.041)与体重差值呈正相关,总运动时间(B=-0.353, P=0.033)、果蔬摄入量(B=-0.618, P=0.008)与体重差值呈负相关。 结论 体检人群疫情暴发后体重较前增加,人群体重增长与饮食、运动、作息等生活方式变化相关,需要关注疫情下健康人群的健康状况并增强健康管理。 Abstract:Objective To explore the related risk factors of life style and health status on physical examination population in the epidemic prevention and control stage, so as to provide a theoretical basis for health intervention. Methods Physical examinees who had a health examination in Peking University First Hospital from June to July 2021 were selected by convenient sampling method, and their body weight and lifestyle changes during the epidemic were analysed through descriptive analysis and inferential analysis by multiple linear regression. Results A total of 392 examinees were enrolled, with a male-to-female ratio of 0. 8∶ 1 and an average age of (38.89±12.45) years old. After the outbreak of the epidemic, the body weight of the physical examination population increased by (0.84±3.24) kg (t=5.135, P < 0.001). According to gender, age group, occupation, education, marital status and BMI stratification, we found that female (t=4.361, P < 0.001), young (t=4.660, P < 0.001), underweight (t=5.231, P < 0.001), normal weight (t=4.378, P < 0.001), married (t=4.221, P < 0.001), employed (t=5.252, P < 0.001) and undergraduate population (t=3.944, P < 0.001) had significant weight gain. Multiple linear regression analysis showed that snack intake (B=0.440, P=0.015), cereal intake (B=0.830, P=0.001) and wake-up time (B=0.430, P=0.041) were positively correlated with body weight changes while total exercise time (B=-0.353, P=0.033) and intake of fruit and vegetable (B=-0.618, P=0.008) were negatively correlated with body weight changes. Conclusion The body weight of the examination population increases after the epidemic, which is related to lifestyle changes such as diet, exercise, work and rest status. It is necessary to focus on the health status of healthy people and strengthen health management in regular epidemic prevention and control stage. -
