Introduction: The osteoblast derived bone formation marker osteocalcin has been reported to decrease adipose tissue in mice. In elderly men, osteocalcin was reported to correlate inversely with fat mass.Aim: To examine the relationship between osteocalcin and regional fat depots.Method: The Odense Androgen Study is a population-based, cross-sectional study of 779 randomly selected men aged 20–29 years. Total, central, upper ex...

Background: Cardiorespiratory fitness is a measure for physical activity and a prognostic health indicator. However, measurement of maximal oxygen consumption (VO2max) is not possible in clinical practice.Aim: We hypothesized that body composition and testosterone levels could be used as possible determinants of VO2max in young men.Participants and design: The Odense Androgen Study, a population-based, observational study including...

Introduction: Low androgen levels are associated with decreased sexual activity. However, to our knowledge no population based study has evaluated the association between androgen levels and sexual activity in young men.Aim: To evaluate associations between androgen levels and sexual activity in young men.Design: Seven hundred and seventy-three Danish men, aged 20–29 years, underwent clinical and biochemical examination: Total...

Background: Birth weight has been associated with low bone mass in later life. Previous studies, however, have relied on self-reported data on birth weight, included select populations, or been of a limited size. Moreover, it is unclear if the association between birth weight and bone mass is be mediated by body weight, lean body mass, or fat mass.Aim: We hypothesize that birth weight is associated with peak bone mass in men independent of current lean b...
