Factors affecting osteoporosis among physical examination populations aged over 35 years in urban areas of Hangzhou City / 预防医学

ABSTRACT

Objective@#To investigate the development of osteoporosis (OS) and its influencing factors among physical examination populations aged over 35 years in urban areas of Hangzhou City, so as to provide insights into OP prevention.@*Methods@#Subjects aged over 35 years that underwent physical examinations in Wenhui Street Community Health Service Center of Gongshu District, Hanghzhou City during the period between April and July, 2022 were enrolled. Subjects' demographic characteristics and physical examination data were collected, and the bone mineral density and serum vitamin D levels were measured. The factors affecting the development of OP were identified using a logistic regression model.@*Results@#A total of 1 561 subjects were recruited, including 616 males (39.46%) with a median (interquartile range) age of 62 (18) years, and 945 females (60.54%) with a median (interquartile range) age of 62 (19) years. The prevalence of OP was 43.69% among the study subjects. Multivariable logistic regression analysis identified women (OR=1.367, 95%CI 1.105-2.979) and increased age (OR=1.057, 95%CI 1.044-1.069) as risk factors for OP and elevated serum 25-hydroxy-vitamin D levels as a protective factor for OP (OR=0.969, 95%CI 0.954-0.985).@*Conclusions@#The prevalence of OP was 43.69% among physical examination populations aged over 35 years in urban areas of Hangzhou City, and gender, age and serum 25-hydroxy-vitamin D were factors affecting the development of OP.
