Abstract

<p><b>目的</b>:地域在住高齢者を対象に,加速度計を用いて座位行動および身体活動を評価し,その詳細なパターンと社会参加の類型との関連を検討すること。</p><p><b>方法</b>:2010年に3地域(東京都文京区・府中市・静岡県小山町)で実施した高齢者調査(対象:当時65~74歳の男女2,700人を無作為抽出)に回答(2,045名)し,追跡調査にも同意した1,314名に対して,2015年に追跡調査を行った。このときに加速度計の装着に同意した478名に,加速度計(HJA-350IT)を連続7日間装着するよう依頼した。座位行動,低強度身体活動(LPA)および中高強度身体活動(MVPA)を評価した。社会参加は国民健康・栄養調査で使用された項目を用いて評価し,個人的活動と地域的活動に類型化した。社会参加の類型と座位行動および身体活動との関連は,年齢,居住地域,同居者の有無,仕事の有無,自動車の運転,body mass index,主観的健康感,身体機能の制限,加速度計装着時間を調整した重回帰分析にて男女別に検討した。</p><p><b>結果</b>:有効なデータは450名より得られた。地域的活動レベルが高いことは細切れ(10分未満)のMVPA(short-bout MVPA)時間が長いことと関連していた(男性:β=1.56,p=0.03,女性:β=2.91,p<0.01)。また,女性では地域的活動レベルが高いことは座位時間が短いこと(β=-11.43,p<0.01)およびLPA 時間が長いこと(β=8.13,p=0.03)と関連していた。</p><p><b>結論</b>:地域的活動への参加を促すことは高齢者のshort-bout MVPAやLPA時間を延長する可能性が示唆された。</p>

<p><b>Objective</b>: The aim of this study was to examine associations of types of social participation and objectively assessed sedentary behavior (SB) and physical activity (PA) patterns in community-dwelling older adults.</p><p><b>Methods</b>: This cross-sectional study was conducted in 2015. The study sample was 1,314 Japanese older adults who were originally randomly selected from three cities (Bunkyo, Fuchu and Oyama) and took part in a community-based survey carried out in 2010. In 2015, participants who agreed to accelerometer survey were asked to wear the accelerometer (Active style Pro HJA-350IT) on their waist for seven consecutive days. SB, light-intensity PA (LPA), and moderate-to-vigorous PA (MVPA) were evaluated. Social participation was examined using question items from the National Health and Nutrition Survey in Japan and was classified into two types; community involvement and individual relationship. Sex-stratified multiple linear regression analysis was used to examine the associations between each type of social participation and patterns of SB and PA after adjustment for age, residential area, living arrangement, working status, driving status, body mass index, self-rated health, physical functioning, and accelerometer wear time.</p><p><b>Results</b>: Data from 450 participants was analyzed. In multiple regression analysis, higher level of community involvement was associated with longer time spent in short-bout (<10 min) MVPA in older men (β=1.56, p=0.03) and women (β=2.91, p<0.01). In women, community involvement was also related to reduced total SB time (β= -11.43, p<0.01) and increased LPA time (β=8.13, p=0.03).</p><p><b>Conclusion</b>: Promoting community involvement may increase short-bout MVPA and LPA time in older adults.</p>
