[The effect of smoking tobacco and drinking of alcohol and coffee on bone mineral density of healthy men 40 years of age].

The aim of the study was to evaluate the effects of smoking, alcohol and coffee drinking on bone mineral content (BMC) in a group of 258 healthy men, aged 40-63, occupationally active inhabitants of Wroclaw. Trabecular, cortical and total BMC at the distal radius of the non-dominant hand were measured by pQCT method using the Stratec apparatus. The data concerning smoking, alcohol and coffee intake were obtained through a questionnaire. The significance of BMC differences between groups were tested using a one-way analysis of variance ANOVA. The extent of alcohol intake did not differentiate BMC values at the distal radius, whereas the significant detrimental effects of both smoking and coffee drinking on trabecular (but not cortical and total) BMC were revealed. Among healthy Polish males coffee drinking was associated with a significant reduction of trabecular BMC. Simultaneously, smokers and ex-smokers (when compared to never-smokers) had lower trabecular BMC.
