Healthcare Management Based on Aging Standardization of Bone Density

<p>　The acquisition of better living habits during youth is known to be important from the medical perspective for the prevention of osteoporosis, but this is important for the prevention of many lifestyle-related diseases, not just osteoporosis. Findings have also been reported that building high bone density in youth slows the onset of osteoporosis and delays arriving at the fracture threshold even when bone density decreases in later years. In this study, we analyze the trends in bone density changes with age and construct an aging evaluation system to explore proposals for health indicators based on bone density evaluations. Bone evaluation figures in which the stiffness value was considered to be bone density were applied to 385 boys in the first to sixth grade of elementary school and 286 boys in the first to third years of junior high school. The age-related change trends were then analyzed from the wavelet interpolation model. Peak stiffness values detected in the aging velocity curve were derived, and the age at maximum peak velocity (MPV) of bone density was identified to be 11.2 years old. This age is younger than the MPV age of 12.6 years old for height and 13.4 years old for weight, and the possibility is conjectured that achieving enhanced bone density on average results in the promotion of height growth. Health management was also explored from proposals for health indicators based on the stiffness value evaluation.</p>
