Determinants of bone density in 30- to 65-year-old women: A co-twin study

Abstract

Reported effects of body composition and lifestyle on bone mineral density in pre-elderly adult women have been inconsistent. In a co-twin study, we measured bone mineral density, lean and fat mass, and lifestyle factors. Analyzing within pair differences, we found negative associations between bone mineral density and tobacco use (2.3-3.3% per 10 pack-years) and positive associations with sporting activity and lean and fat mass. Introduction: Reported effects of body composition and lifestyle of bone mineral density in pre-elderly adult women have been inconsistent. Methods: In a co-twin study of 146 female twin pairs aged 30 to 65 years, DXA was used to measure bone mineral density at the ..
