Associations of Exercise Habits in Adolescence and Old Age with Risk of Osteoporosis in Older Adults: The Bunkyo Health Study

Abstract

We investigated effects of exercise habits (EHs) in adolescence and old age on osteoporosis prevalence and hip joint and lumbar spine bone mineral density (BMD). Body composition and BMD in 1596 people aged 65–84 years living in Bunkyo-ku, Tokyo, were measured using dual-energy X-ray absorptiometry. We divided participants into four groups by a combination of EHs in adolescence and old age: none in either period (None-None), only in adolescence (Active-None), only in old age (None-Active), and in both periods (Active-Active). Logistic regression models were employed to estimate multivariable-adjusted odds ratios (ORs) for osteoporosis determined by T-score (less than −2.5 SD) using the None-None reference group. In men, the combination of EHs in adolescence and old age was not associated with osteoporosis prevalence. However, the lumbar spine’s BMD was significantly higher in the Active-Active than the None-Active group (p = 0.043). In women, the Active-Active group had lower lumbar spine osteoporosis prevalence than the None-None group (OR 0.65; 95% CI, 0.42–1.00, p = 0.049). Furthermore, hip BMD was significantly higher in the Active-Active group than in the other three groups (p = 0.001). Older women with EHs in adolescence and old age had higher lumbar BMD and lower risk of osteoporosis.

Playing basketball and volleyball during adolescence is associated with higher bone mineral density in old age: the Bunkyo Health Study

“…This cross-sectional study used the baseline data from the Bunkyo Health Study ( Someya et al, 2019 ; Otsuka et al, 2021 ). The Bunkyo Health Study recruited adults aged 65–84 years living in Bunkyo-Ku, an urban area in Tokyo, Japan.…”

Anterior meniscus extrusion is associated with anterior tibial osteophyte width in knee osteoarthritis – The Bunkyo Health Study

“…The BHS is a prospective cohort study over 10 years to identify risk factors for needing long-term care [ [24] , [25] , [26] ]. Elderly subjects between 65 and 84 years of age living in Bunkyo-ku, an urban area in Tokyo, Japan were recruited, and a total of 1630 subjects participated from November 2015 to September 2018.…”

“…In the present study, we examined the prevalence of ATO and AME and explored whether there is any association between AME and ATO width among elderly populations using data from the large-scale cohort study, the Bunkyo Health Study (BHS) [ [24] , [25] , [26] ].…”

Medial meniscus extrusion is invariably observed and consistent with tibial osteophyte width in elderly populations: The Bunkyo Health Study

“…We organized the Bunkyo Health Study, a prospective cohort study over 10 years to identify risk factors for needing long-term care [27][28][29][30] , and recruited elderly subjects aged between 65 and 84 years and living in Bunkyo-ku, an urban area in Tokyo, Japan. A total of 1,630 subjects participated during a period from November 2015 to September 2018.…”

“…In the present study, asymptomatic elderlies in a population-based large cohort [27][28][29][30] were subjected to radiographic and MRI examinations to analyze the knee OA changes. We developed a new method to analyze both cartilage and bone parts of osteophyte by pseudo-coloring the MRI views and studied correlations between MME and medial tibial osteophyte width, together with prevalence of MME.…”
