最近天氣冷，加上霾害破表，間接影響到類風濕性關節炎（Rheumatoid arthritis，簡稱RA）的病患，不少民眾想知道究竟有甚麼方法能降低發病機會？

《風濕病》（Rheumatology）刊載的新研究發現，患有類風濕性關節炎風險的民眾，若透過魚、魚油攝取較多omega-3脂肪酸，可以降低發病機會。

**女性罹病率更高 類風濕性關節炎致早死**

美國疾病控制和預防中心（CDC）表示，患有類風濕性關節炎的病患，免疫系統會對患者自身組織發動攻擊，導致疼痛、腫脹和僵硬，甚至會有殘疾、過早死亡的風險，無論幾歲都可能發病，女性罹患RA的機率又比男性高三倍。

儘管目前尚未找到類風濕性關節炎的確切病因，不過，醫生推測基因、環境、荷爾蒙都是致病的主因。此外，現今也沒有治療類風濕性關節炎的方法，但是，特定的運動技巧有助於控制病情，也有一些證據顯示，飲食可能有所幫助。

**攝取適量魚油 降低發病風險**

研究人員分別針對30名患有類風濕性關節炎受試者與47位非患者當作對照組，觀察他們的Omega-3攝取量。對照組中有達近4成的人會補充omega-3，而患有類風濕性關節炎的民眾卻只有6.7%的人服用。血液檢查也顯示，那些類風濕性關節炎病患「顯著可能」比對照組平均攝取更少的omega-3脂肪酸。關鍵可能就出在Omega-3中的DHA與EPA，可能有效抑制特定蛋白質，調節免疫反應。

研究主持人，科羅拉多公共衛生學院流行病學系諾里斯（Jill Norris）教授表示，有攝取Omega-3的人，和沒攝取的人，血液中的Omega-3濃度有非常顯著的差異。諾里斯教授進一步強調，基因可能是扮演啟動Omega-3效果的關鍵角色，對於那些罹患類風濕性關節炎風險的患者，應以健康均衡的飲食，包含魚類含有豐富的Omega-3脂肪酸，也就是攝取適量魚油，以降低發病風險。
