日野町におけるロコモ健診受診・非連続受診の要因検討　-　2年間の追跡調査：GAINA study -

The aim of this study in residents living in Hino town in the Tottori prefecture was to determine the factors related to them continuing to receive annual medical check-ups. A total of 223 subjects participated in the study and received a baseline assessment that included a blood test, measurement of bone mass, muscle mass, pain, gait speed, and grip strength, recording whether or not the locomotive syndrome or sarcopenia were present, and the incidence of falls and fractures. Yearly follow-up assessments were performed in the two-year period after the baseline assessment. The subjects were stratified into two groups: continuing to receive medical check-ups during the three years （G1） and not receiving medical check-ups over the two-year follow-up period （G2）. Ninety-seven subjects received medical check-ups over three years, while 17 subjects received a baseline assessment but never had follow-up assessments despite answering a postal follow-up questionnaire. Taking analgesic medicine at the baseline assessment was significantly higher in the G2 group than in the G1 group. The incidence of fractures was also significantly higher in the G2 group than in the G1 group at the follow-up assessment. Multiple regression analysis showed sarcopenia was the factor that had the most influence on the subjects continuing to receive medical check-ups. By causing a loss of muscle mass and lower physical performance, sarcopenia may prevent residents from maintaining regular healthcare behavior.
