老年人肥胖與認知受損關係之研究

An Investigation on the Correlation between Senior Obesity and Cognitive Impairments

老年人肥胖與認知受損的關係目前仍尚未明確。本研究旨在使用不同體位評估方 法，探討肥胖與老年認知受損的關係。本研究係橫斷性研究，受試者是 307 位高雄市湖 內區 65 歲以上的老年人。依變項為認知受損，採用簡易智能測驗（Mini-mental state examination）進行測量。體位部分共採用身高與體重計算身體質量指數（Body Mass lndex）、腰圍（waist circumference）以及透過生物電阻分析（Bioelectrical lmpedance Analysis） 測量體脂率等。共變項包括：性別、年齡、教育程度、婚姻、收入、吸菸、喝酒、慢性 疾病等。經由多元邏輯迴歸模式分析，本研究發現：BMI、腰圍、體脂率均與認知受損 無顯著關係。由於本研究僅係橫斷性調查，未來仍需要透過前瞻性研究進行驗證。

The relationships between obesity and cognitive impairment in older populations are still unclear. This study aimed to examine this relationship using different methods of assessing weight status in comm unity - dwelling older adults. A cross - sectional survey was conducted with 307 community - dwelling older adults aged 65 or older in Kaohsiung, Taiwan. Cognitive impairment was measured by the mini mental state examination (mini - mental state examination). The assessment of weight status included body mass index ( body mass lndex ) , waist circumference ( waist circumference ) , and body fat using bioelectrical Impedance Analysis. Covariates comprised sex, age, educational level, marital status, income, smoking, alcoho l consumption, number of chronic diseases. After multivariable adjustment, multiple logistic regression models revealed that BMI, waist circumference and body fat were not significantly associated with cognitive impairment. Given that it was a cross - sectio nal study with a small smaple, a well - designed prospective study is needed to verify these findings.
