Objective: To understand the physical activity and regular exercise status and influencing factors of people with high risk of chronic diseases among Beijing residents, and to provide science basis for health education strategies and intervention measures.
Methods: 13 200 participants aged 18-79 were selected by stratified cluster sampling method for questionnaire survey in 2017.3448 participants without hypertension, diabetes and dyslipidemia met the criteria of high risk population. The metabolic equivalent of physical activity was calculated by referring to the summary of physical activity in the United States and the global physical activity questionnaire.
Results: 1794 male(52.0%) and 1654 female(48.0%) are included in this study. 862(25.0%) are 18-29 years old, 778(22.6%) are 30-39 years old, 640(18.6%) are 40-49 years old, 709(20.6%) are 50-59 years old, and 193(13.3%) are 60-79 years old. 684 participants(18.6%) are low physical activity level, 1480 participants(42.9%) are medium level and 1284 respondents(37.2%) are high level. The rate of never exercising is 60.2%. Multivariate analysis shows female(OR=1.32, 95%CI 1.11-1.55), aged 40-49(OR=1.34, 95%CI 1.04-1.72) and aged 50-59(OR=1.76, 95%CI 1.36-2.28) participants are likely to have high level physical activity. Participants with high education level(OR=0.78, 95%CI 0.66-0.93) and insufficient intake of fruits and vegetables(OR=0.73, 95%CI 0.64-0.84) are likely to have low physical activity level. Female(OR=1.46, 95%CI 1.22-1.76), participants with insufficient intake of fruits and vegetables(OR=1.44, 95%CI 1.24-1.69) are likely never to exercise. Participants with high education level(OR=0.46, 95%CI 0.38-0.55), high school education(OR=0.63, 95%CI 0.53-0.75), no job(OR=0.67, 95%CI 0.56-0.81) are likely to exercise.
Conclusion: The population with high risk of chronic diseases in Beijing City was lack of physical activity. Gender, age, education level, fruit and vegetable intake are the influencing factors of physical activity level, while gender, fruit and vegetable intake, education level, marriage, employment and fruit and vegetable intake are the influencing factors of exercise.
