Purpose: The aim of this study was to assess the relationships of bone mineral density (BMD) with current leisuretime physical activity (LTPA) and adolescent exercise (AEX) among the middle-aged and elderly in Japan. Methods: The data for the present study were derived from the baseline data or the National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA). Subjects consisted of 1017 male (58.5 ± 10.8 years) and 577 postmenopausal female (62.6 ± 8.4 years). Those who had osteoporosis, rheumatoid arthritis or cancer were excluded from the subjects. Those who used thyroid hormone or parathyroid hormone were also excluded. Subjects were interviewed about their physical activity habits during leisure time throughout the past twelve months and about exercise they engaged in during adolescence (12 to 20 years). Subjets were divided into 3 groups according to the intensity of LTPA, 'no LTPA', 'lightLTPA' and 'moderate or heavy LTPA'. They were also divided into 2 groups, with or without AEX. BMD was measured with a dual energy X-ray absoptiometry (DXA; Hologic QDR-4500A), in g/cm^2. Measurement sites were the whole body (WT), L2-L4 lumber spine (L24), femur neck (FN). Ward's triangle (WT), and trochanter (TR). Relationships of BMD with LTPA and AXE were analyzed using analysis of covariance controlled for age, height and weight. Significant probability levels were less than 0.05. Results: Average BMD (SD) at WB, L24, FN, WT, TR were 1.09(0.10), 0.99(0.16), 0.76(0.11), 0.56(0.13), 0.67(0.11) in male and 0.93(0.11), 0.82(0.16), 0.66(0.10), 0.47(0.14), 0.55(0.10) in female, respectively. The proportion of subjects with LTPA was 75.5% in male and 67.7% in female. The subjects that engaged in AEX represented 65.7% in male and 39.5% in female. The result of analysis of covariance controlled for age, height and weight was as follows; in male, LTPA showed significant main effect on BMD at FN, WT and TR. AEX showed significant main effect on BMD at all sites. However, there was no interaction effect on BMD at all sites. As for female. LTPA showed significant main effect on BMD at FN and TR. AEX showed significant main effect on BMD at TR. There was a significant interaction effect on BMD at WB and FN. Conclusion: The results suggested that not only current leisure-time physical activity but also adolescent exercise benefits bone mineral density among middle-aged and elderly people in Japan.
