摘要

背景：腹部肥胖是各國重要的健康議題亦是代謝症候群的主要因子。故瞭解導致腹部肥胖的因子甚為重要。
目的：本研究的目的在探討台灣中老年人腹部肥胖的關聯因子。並分析飲食狀況對四年及八年之後腹部肥胖風險的影響。
方法：本研究資料來源為國民健康局的「台灣地區中老年身心社會生活健康狀況長期追蹤調查研究」。以2003年共3377人及2007年共2695人完訪個案並有1999年飲食狀況資料者為對象。以邏吉斯迴歸分析2003年及2007年的人口學、社經情形、生活方式、健康狀況等變項，及1999年的飲食狀況與腹部肥胖的關聯，及預測腹部肥胖的能力。
結果：邏吉斯迴歸分析結果顯示，食慾佳(OR=1.75, 95% CI:1.11-2.74, p=0.02)、女性(OR=1.49, 95% CI:1.20-1.86, p<0.001)、高齡(OR=1.50, 95% CI: 1.06-2.16, p=0.02)、有喝酒習慣(OR=1.27, 95% CI:1.02-1.60, p=0.04)、有飲茶(葉) (OR=1.26, 95% CI:1.06-1.49, p=0.008)，及有高血壓(OR=1.81, 95% CI: 1.55-2.10, p<0.001)、糖尿病(OR=1.68, 95% CI: 1.39-2.04, p<0.001)、心臟病者(OR=1.36, 95% CI: 1.12-1.66, p=0.002)皆增加腹部肥胖的風險；而抑鬱者(OR=0.79, 95% CI: 0.64-0.98, p=0.03)及每週攝取乳品≥3次者(OR=0.82, 95% CI:0.71-0.95, p=0.01)與腹部肥胖呈顯著負關聯。
結論：本研究顯示食慾、女性、高齡、糖尿病、高血壓、心臟病、喝酒及飲茶(葉)為腹部肥胖的顯著正關聯因子；抑鬱狀態及毎週攝取乳品類≥3次為腹部肥胖的負關聯因子，且研究結果顯示食慾可預測未來腹部肥胖的風險。本研究為以長期追蹤調查資料探討台灣中老年人腹部肥胖的關聯因子，結果可供有關單位研擬預防保健政策的參考。

Background and objective: Abdominal obesity is a significant health issue in most countries. It is also a major risk factor of metabolic syndrome. Hence, there is a need to understand the factors that are associated with abdominal obesity.
Method: Data for this analysis were the 1999, 2003 and 2007 datasets of “The Survey of Health and Living Status of the Elderly in Taiwan” conducted by the Bureau of Health Promotion of Taiwan. Subjects were 3377 persons who completed the 1999 and 2003 surveys and 2695 persons who completed 1999 and 2007 surveys. Logistic regression analysis was conducted to determine the association of abdominal obesity with demographic, social-economic, lifestyle, and health-related variables in 2003 and 2007, and with food consumption frequencies of the major food items 1999.
Results: The results showed that good appetite (OR=1.75, 95% CI:1.11-2.74, p=0.02), female (OR=1.49, 95% CI:1.20-1.86, p<0.001), older age (OR=1.50, 95% CI: 1.06-2.16, p=0.02), alcohol-drinking (OR=1.27, 95% CI:1.02-1.60, p=0.04), tea-drinking (OR=1.26, 95% CI:1.06-1.49, p=0.008), hypertension (OR=1.81, 95% CI: 1.55-2.10, p<0.001), diabetics (OR=1.68, 95% CI: 1.39-2.04, p<0.001) and having heart disease (OR=1.36, 95% CI: 1.12-1.66, p=0.002) were positively associated with increased risk of abdominal obesity, whereas depression (OR=0.79, 95% CI: 0.64-0.98, p=0.03) and more frequent dairy consumption (OR=0.82, 95% CI:0.71-0.95, p=0.01) were negatively associated with abdominal obesity.
Conclusion: Results of the present study suggest that good appetite is the chief contributing factor to abdominal obesity. Other factors that impact the risk of abdominal obesity positively or negatively are probably mediated through changing appetite or energy intake status. Results of this study can provide useful information for designing effective health-promotion policies for older Taiwanese.
