The purpose of this study was to investigate the relationship between cognitive function and physical performance in Japanese older adults. Ninety four older adults, aged 65 to 87 years (mean age 71.9±5.3 years), were recruited as participants. Cognitive function was evaluated by Five-cognitive Function Test (FCFT). The FCFT, which was developed specially for Japanese older adults, consists of 5 subscale elements: attention, verbal memory, visuospatial cognition, word fluency, and associate learning. Hand dexterity (3 items), muscle strength (2 items), balance (3 items), flexibility (2 items), walking ability (2 items) and reaction ability (2 items) were defined as lifestyle-related physical performances. After adjusting for age, educational level and systolic blood pressure the FCFT score was significantly correlated with observed data of hand dexterity (hand working with a peg board, r=0.485, p<0.001), lower-extremity muscle strength (5-repetition sit-to-stand, r=-0.231, p<0.05), walking ability (5-m habitual walk, r=-0.225, p<0.05; timed up and go r=-0.304, p<0.01), and reaction ability (simple reaction time, r=-0.415, p<0.001; 4-way choice reaction time, r=-0.401, p<0.001). Multiple regression analysis revealed that the FCFT score was explained by the hand working with a peg board (F=42.36, p<0.001) and 4-way choice reaction time (F=29.62, p<0.01). The contribution rate on this model was 42%. These results suggest that cognitive functions were associated with some physical performance. Especially, hand dexterity (hand working with a peg board) and reaction ability (4-way choice reaction time) may be the useful synthetic indicators of cognitive functions in Japanese older adults.

目的:高齢者の身体活動量に関連する重要な要因として,外出形態,抑うつ度,ソーシャルネットワークに焦点を当て,これらの要因と余暇活動量,家庭内活動量,仕事関連活動量との関連性について明らかにすることを目的とした.方法:茨城県笠間市の住民基本台帳を用いて,65歳から85歳の高齢者2,100名を無作為抽出し,有効回答の得られた340名(有効回答率16.2%)を分析対象とした.身体活動量の評価には,Physical Activity Scale for the Elderly,抑うつ度の評価にはGeriatric Depression Scale(GDS),ソーシャルネットワークの評価には,Lubben Social Network Scale(LSNS)を用いた.主要な分析には,重回帰分析(強制投入法)を用いた.目的変数には各身体活動量を,説明変数には仮説として身体活動量と関連すると想定した項目および基本属性に関する項目を設定した.結果:重回帰分析の結果,余暇活動量は,自転車利用頻度(β=0.17),LSNS得点(β=0.17)と有意に関連した.家庭内活動量はLSNS得点(β=0.21)と関連した.仕事関連活動量は乗物利用頻度(β=0.25)と関連した.総活動量は,自転車利用頻度(β=0.10),乗物利用頻度(β=0.23),GDS得点(β=-0.16),LSNS得点(β=0.23)と関連した.結論:本研究では自転車や乗物の利用頻度が,余暇活動量および仕事関連活動量を反映することを示した.また,ソーシャルネットワークは,余暇活動量と家庭内活動量の両方と関連する重要な因子であることを明らかとした.

The purpose of this study was to examine whether volunteering as exercise instructors over a continuous period of time affected the physical and cognitive functions of community-dwelling, elderly women. Longitudinal analysis was conducted on data from 18 volunteer leaders (Leader group) aged 65-79 years (69.6 ± 3.9 years) and 18 age-matched survey participants (Control group). We evaluated physical function using 8 physical performance tests along with their standardized total score, and we evaluated cognitive function using the Five Cognitive Function Test. We used two-way ANOVA to examine the effectiveness of engaging in a yearlong volunteer activity and Cohen's d for effect size. There were significant interactions in timed up and go, hand working with pegboard, standardized score of performance tests and the Five Cognitive Function Test score (P < 0.05). The Leader group improved significantly in sit and reach (d = 0.55), 5-repetition sit-to-stand (d = 0.77), timed up and go (d = 0.77), 5-m habitual walk (d = 0.88), 4-way choice reaction time (d = 0.86), standardized score of performance tests (d = 0.96) and the Five Cognitive Function Test score (d = 0.93). Although the Control group also improved significantly in some tests, the effect size tended to be lower: sit and reach (d = 0.49), hand working with pegboard (d = 0.57), standardized score of performance tests (d = 0.38) and the Five Cognitive Function Test score (d = 0.54). These results suggest that volunteering as an exercise instructor improves volunteers' physical and cognitive functions.
