中文摘要 | 目的:探討比較老年人之不同休閒時間身體活動劑量對糖尿病盛行率之差異,並同時混合交互分析老年人不同身體質量指數及平時休閒時間身體活動狀況對糖尿病盛行率之影響。方法:本研究使用衛生署國民健康局「台灣地區中老年身心社會生活狀況長期追蹤調查」2007年資料檔為研究基礎,以65歲以上老年男女計2,700人做為樣本基礎資料來源,將受檢者之身體質量指數依國民健康署對國人體型之分類標準,分為體重正常、過輕、過重與肥胖等4種體型,及將受檢者平時休閒時間身體活動狀況,分成無身體活動習慣、低身體活動量、高身體活動量等不同劑量之3組,並同時以2007年當年受檢者之糖尿病盛行率為分析依據,然後將所有資料登錄並以多變項羅吉斯迴歸模式分析。結果:資料顯示無論高、低身體活動劑量組之糖尿病勝算比,皆顯著低於無身體活動習慣之受檢者(AOR分別為0.64, 95% CI: 0.48-0.85; 0.69, 95% CI: 0.53-0.91)。而由於體重過輕受檢者之糖尿病勝算比顯著低於體重正常受檢者,因此在身體質量指數分層與不同身體活動量分析時,排除掉體重過輕之受檢者,結果高、低身體活動劑量之肥胖受檢者之糖尿病勝算比,顯著低於無身體活動習慣之肥胖受檢者(AOR分別為0.41, 95% CI: 0.22-0.47; 0.47, 95% CI: 0.26-0.88),但體重過重之受檢者,則並不顯著。當將受檢者之身體質量指數與休閒時間身體活動混合交互分析,以體重正常但無身體活動習慣之受檢者為對照組,則只有體重正常但有運動之受檢者達顯著水準(AOR為0.70, 95% CI: 0.50-0.99),其餘過重、肥胖等但有運動之受檢者則皆不顯著。結論:綜合上述結果,本研究發現休閒時間身體活動劑量顯著影響老年人糖尿病盛行率之差異,即便較低之身體活動劑量仍能降低罹患糖尿病之風險,但身體質量指數似乎大於休閒時間身體活動對糖尿病盛行率之影響。 |
英文摘要 | Objectives: To examine the influences of leisure-time physical activity and body mass index (BMI) on the prevalence of diabetes in older adults. Method: The study was based on nationally representative data from the 2007 Survey on Health and Living Status of the Elderly in Taiwan with a cohort of 2700 participants aged 65 and older analyzed. The subjects were classified into 4 groups (normal/ underweight/ overweight/obese) according to BMI defined for adults by the Department of Health. Physical activity patterns was examined based on the participants' self-reported frequency and duration of physical activity per week at baseline according to 3 categories of activity status (none/low/high). Multivariate logistic regression analyses were conducted to assess the separate and joint associations between dose-response of physical activity and BMI on diabetes prevalence. Results: Compared to those who reported no physical activity, participants engaging in low- or high-level physical activity showed a significantly lower risk of diabetes with a multivariate-adjusted odds ratio (AOR; 0.64, 95% CI: 0.48-0.85; 0.69, 95% CI: 0.53-0.91). A similar result was observed in obese subjects. The AORs of obese participants with a low level and a high level of physical activity read respectively 0.41 (95% CI: 0.22-0.77) and 0.47 (95% CI: 0.26-0.88), both lower than that of their inactive counterparts. There was no significant difference in the group of overweight participants. After combined analysis, only normal-weight active subjects reported a significantly reduced risk (AOR, 0.70, 95% CI: 0.50-0.99) absent in overweight and obese participants (weather active or inactive) as well as in normal-weight inactive individuals (underweight subjects were excluded from analysis based on results stratified by BMI since there was a general reduction in diabetes risk among underweight subjects as compared to normal-weight subjects). Conclusions: The dose-response of leisure-time physical activity in later life is related to low risk of diabetes; even a low level of physical activity can be beneficial. However, the influence of BMI appears to be more important than that of physical activity in combined analysis. |
