Abstract Objective To investigate the prevalence of bone mineral density (BMD) level and osteoporosis in women aged 40-55 years old in Gansu province and to analyze the related factors on osteoporosis. Methods Cross-sectional survey was applied from March to October in 2016 and the subjects were women aged 40-55 years old. A questionnaire survey was conducted and BMD was measured on 2 683 women in 162 townships among 54 districts / counties in Gansu province by multi-level, group and random method. The incidence of osteoporosis in different groups was compared. Statistical analysis was performed by χ2 test and binary Logistic multifactor regression analysis. Results In the 2 683 women, the rate of osteoporosis was 17.0% (457/2 683) . The incidence of osteoporosis in different age, different BMI groups and different menstrual conditions were statistically significant (χ2=12.69, 18.61 and 10.34, respectively, all P﹤0.05). The proportion of osteoporosis was 18.4% (141/768) in 51-55 years old group, higher than that of 40-45 years old group. The proportion of osteoporosis was 31.0% (27/87) in obesity group, higher than that of low body weight group, normal weight group and overweight group. The proportion of osteoporosis was 20.6% (142/688) in menopausal group, higher than that of premenopausal group and postmenopausal group. Binary Logistic multifactor regression analysis showed that the higher the BMI, the higher risk of osteoporosis (OR=1.068, 95%CI: 1.026～1.111, P﹤0.05). Conclusions In Gansu province, women aged 40-55 years old have a different degree of loss of bone mass. Women with menopause or higher BMI were more likely to suffer from osteoporosis. Health education should be actively carried out to prevent the occurrence of osteoporosis and complications.
