[Relations between alcoholism and osteoporosis or femoral head necrosis].

Objective: To explore the relationship of alcoholism between osteoporosis or femoral head necrosis.

Methods: In this case-control study, we selected 95 eligible patients with femoral head necrosis and another 67 cases of osteoporosis as case group, together with 342 patients of fractures from the Second Hospital affiliated to Shanxi Medical College, from February to December 2010, as the control group. Questionnaire was used to collect general information of the patients. Through comparative analysis, related factors of femoral head, osteoporosis were defined. 18 patients with alcoholic femoral head necrosis, 11 patients with alcoholic osteoporosis and 20 patients with fractures were selected from the above said three groups and going through the Alcohol Use Disorders Identification Test (AUDIT) as well as the Alcohol Use Disorders Scale(ADS). Using SPSS 13.0 conducted one-way ANOVA(analysis of variance), chi-square test, categorical logistic regression analysis were used for statistical analysis.

Results: Results from logistic regression analysis showed that the adjusted odds ratio of those subjects who liked drinking alcohol had an incidence of femoral head necrosis or osteoporosis as 7.70 (95% CI:1.84, 32.30) and 8.44 (95% CI:1.70, 41.90), respectively. The risks of using hormone for treating femoral head necrosis or osteoporosis were 78.43 (95%CI:11.20, 149.05) and 22.75 (95%CI:2.59, 100.27) times than those without. Data from the AUDIT showed that:over-dose of alcohol drinking habit existed 100% in the femoral head necrosis group while 54.45% in the osteoporosis group, while 75 percent patients in the fractures group had normal alcohol drinking habit. Statistically significant differences appeared in the three groups (P < 0.01).

Results: from the ADS showed that there were statistically significant differences between the ADS scores of the three groups(F = 3.68, P = 0.03).

Conclusion: Alcohol intake did seem to be highly correlated with the incidence rates of femoral head necrosis or osteoporosis. Alcohol-related necrosis could be viewed as alcohol-dependent diseases while alcohol-related and osteoporosis could partially be recognized as alcohol-dependent disease.
