Effects of tobacco use on axial and appendicular bone mineral density
Tobacco use has been identified as being a risk factor for the development of osteoporosis. While some data have suggested an effect on peripheral bone mass there are little previous data examining the role of tobacco use in axial skeletal bone loss. We examined tobacco use in relation to lumbar spine and proximal femur bone mineral density and forearm bone mineral content in 203 women. Data from identical twin pairs, comprising a subgroup of the larger group as well as a small number of male twin pairs, was also analyzed. The data show a difference in lumbar and proximal femur BMD of 0.03 and 0.06 g/cm2 respectively between smoking and nonsmoking identical twins. There was however no difference in the cross-sectional studies and no significant deleterious effect detected of tobacco use on forearm bone mineral content. The effect of smoking on lumbar and proximal femur bone mineral density, in identical twins discordant for tobacco use, was equivalent on average to 3 to 4 years of normal postmenopausal bone loss.
