| Objective To explore the incidence and the risk factors of osteoporosis ( OP) in Mongolians of west Inner Mongolia region, so as to get targeted intervention.Methods Three hundred Mongolian healthy people were continuously extracted from the health examination center of the Affiliated Hospital of Inner Mongolia Medical University.Forty-three cases were diagnosed of OP. They were in the case group.Eighty-six cases were randomly selected from 257 non-OP people as control group.Seventeen indexes including age, height, and body mass index were compared between the two groups.Single factor analysis and multi-factor logistic regression were conducted.Results The prevalence of OP was 14.33%.The analysis of OP-related factors showed that after excluding other roles into the model, every 1-year increase of age and every 1-unit increase of body mass index increased the OP risk by 1.10 and 1.21 times, respectively (OR 1.10 and 1.10, 95%confidence interval not containing 1, P<0.05).Urban living and less intake of vegetables increased the OP risk by 3.85 and 3.82 times more than farm living and more intake of vegetables ( OR 3.85 and 3.85, the 95%confidence interval not containing 1, P<0.05).Male gender with more drinking increased the OP risk comparing to females and less drinking (OR 0.41 and 0.11, the 95% confidence interval not containing 1, P<0.05).Females were more vulnerable to OP.Drinking in women prevented the occurrence of the disease.Conclusion Age, body mass index increase, urban residential, less vegetable intake, and female gender are OP risk factors.More drinking is the protective factor. |
