Abstract: | 摘要 背景與目的 綠地指部分或完全被草、樹或其他植被所覆蓋的土地,例如公園、行道樹或花園等。綠地會藉由淨化周遭環境與提供運動交流之場地而提升人民健康。過去文獻指出綠地與過胖及肥胖之負相關,較少研究探討體組成與綠地之關聯。本研究旨在評估住宅鄰近綠地對老年人身體組成之關聯性。 材料與方法 研究在2016年至2018年期間,共收集了1,356名老年人(年齡≥65歲)進行基礎健康檢查,通過生物電阻抗分析來測量身體成分,如:肌肉骨骼重及脂肪重。問卷收集相關的資料包含基本人口學特性、醫療病史及生活習慣等。鄰近綠地是使用兩個指數進行估算:歸一化植被指數(NDVI)和第二次台灣土地利用調查。我們計算了每個參與者居住地500米以內的公園森林佔比和NDVI的年平均。使用多元線性回歸來確定鄰近綠地與身體組成之間的關聯。以ArcGIS軟體依住家地址進行定位與環域分析,使用SAS9.4軟體整合資料與統計數據。 結果 總共有1,356名年長者參加。受測者住家鄰近之公園佔比平均為3.1%(標準差為3.7 % ),森林佔比平均為2.9%(標準差為7.1 % )及NDVI平均值為0.29 (標準差0.13)。在調整抽菸狀況、飲酒狀況、檳榔、年齡及慢性疾病後公園面積與男性骨骼肌質量有正相關(β= 0.09 (SE=0.04), p = 0.04),且在女性體脂肪量(β= -0.2 (SE=0.1), p = 0.04)和體脂率(β= -0.58 (SE=0.22), p = 0.01)呈負相關。且運動的頻率改變了公園對老年婦女體內脂肪百分比的觀察效果。NDVI並無觀察到與體組成的作用。 結論 鄰近公園對老年人體內脂肪量和骨骼肌量都是有益的。 Green spaces as the land that is partly or completely covered with grass, trees, or other vegetation which includes parks, community gardens, and cemeteries. Green space also promotes physical activity, psychological well-being, and the general public health of urban residents. Loss of skeletal muscle mass is common with aging and can cause morbidity and mortality in the elder. The study aims to assess the effects of residential green space on the body composition of the elders. A cross-sectional health exam in five hospitals for 1,356 elders (age ≥ 65 years) was conducted in Taiwan during 2016-2018. The body composition was measured by bioelectrical impedance analysis. Residential greenness was estimated using two indices – the Normalized Difference Vegetation Index (NDVI) and the Land Use Investigation of Taiwan. We calculated the percentage of green space (park, forest) and NDVI annual average within 500 meters of each participant's residence. Multiple linear regression was used to determine the association between residential green space and body composition, after adjustments for demographics, personal habits and physician-diagnosed diseases. A total of 1,356 elder were enrolled. After adjusting, park was associated with higher skeletal muscle mass (β= 0.09 (SE=0.04), p = 0.04) in elderly men, but negative relationship in body fat mass (β= -0.2 (SE=0.1), p = 0.04) and percent body fat(β= -0.58 (SE=0.22), p = 0.01) in elderly women. No such association was found between NDVI and body composition. Frequency of physical activity modifies observed effect of park area on percent body fat in elderly women. These findings suggest that residential park is beneficial for body fat mass in elderly women and for skeletal muscle mass in elderly man. |
