Abstract

Objective: The increasing number of osteoporosis patients is one consequence of our rapidly aging society. More specifically, post-menopausal women experience a marked decrease in bone mass. As the highest possible peak bone mass must be acquired during young adulthood, we evaluated the correlation of the physical characteristics and lifestyle habits with bone mass indexes in Japanese female high school students.

Methods: The speed of sound (SOS) and osteo sono assessment index (OSI) of the talipes calcaneus were measured as bone makers among 16- and 17-year-old female high school students. The students also responded to a questionnaire survey about their characteristics and lifestyles. To evaluate the correlations of various factors with SOS and OSI, a forced-entry multiple regression analysis was conducted. For this, SOS and OSI were used as dependent variables and height, body weight, grip strength, sleep environment, sports club participation, and current ingesting milk as independent variables.

Results: The standard partial regression coefficient revealed significant correlations of SOS with body weight (β=0.150, p<0.05) and, a stronger correlation with sports club participation (β=-0.224, p<0.01). For OSI, the strongest correlation was observed with sports club participation (β=-0.193, p<0.01), followed by body weight (β=0.157, p<0.05) and the sleep environment (β=-0.132, p<0.05). It was shown that exercise club participation had the strongest influence on SOS and OSI.

Conclusion: Sports club participation and body weight were positively correlated with increased bone mass indexes, and it was suggested that participation in exercise club activities was most important for acquiring bone mass.
