Background

The prevalence of asthma has increased in recent years. Epidemiological studies suggest a correlation between the onset of asthma and dietary nonallergic factors especially high calorie diet. These can be regarded as other potentially important risk factors.

Objectives

To observe the effect of dietary calorie reduction on chronic asthma in adults or children.

Search methods

We searched the Cochrane Airways Group Specialised Register of trials using prespecified terms. We assessed bibliographies from included studies, and contacted authors of known studies for additional information about published and unpublished trials. Date of most recent search: May 2006

Selection criteria

Randomised-controlled trials of dietary calorie reduction were included.

Data collection and analysis

Three authors assessed each study independently. Disagreement was resolved by consensus. Quality assessment was performed independently.

Main results

One trial of fair methodological quality with a total of 38 patients suffering from chronic asthma was included. There were significant increases in FEV1 and FVC in the active treatment group compared with control. No data pertaining serious adverse effects were reported from the interventions.

Authors' conclusions

There is currently a very small amount of evidence assessing the effects of dietary interventions intended as part of a wide-ranging weight-loss programme. Whilst we are unable to recommend these strategies as concomitant interventions with drug-based therapy for the specific management of asthma, dietary interventions such as weight-loss programmes may provide benefits in specific patients. However, the impact of a calorie-controlled diet on the signs and symptoms of asthma in the general asthmatic population is yet to be established.

Calorie-controlled diets for chronic asthma

It is thought that high calorie diets may contribute to the development of asthma. Theoretically, reducing the amount of calorie consumed as part of a diet may help to alleviate the symptoms of asthma. This review was limited by the small size of the studies and the obese population of asthma patients recruited to the study. No firm conclusions can be drawn regarding the effects of dietary manipulation, and more research is required.

背景

藉由控制飲食熱量來治療慢性氣喘

近年來,氣喘的流行程度有越趨增加的趨勢。流行病學的研究推測,氣喘的發作和飲食中非過敏因子(特別是高熱量食物)有某種程度的相關性,因此這些飲食中非過敏因子可以被視為潛在的重要危險因子。

目標

本研究的主要目的在於觀察飲食中熱量減少對於幼童或成人慢性氣喘的影響。

搜尋策略

我們利用一些預先設定的項目來搜尋Cochrane Airways Group Specialised Register中的試驗。我們由納入的試驗來評估一些參考資料,並且聯繫一些已知研究的作者以取得其他已公開或未公開的試驗資料。檢索至2006年5月。

選擇標準

本研究納入了設計有降低飲食中熱量控制組的隨機性對照試驗。

資料收集與分析

有三個研究人員分別針對每一個試驗進行評估,意見上的差異則利用共識來進行調整。不同研究之間的品質評估也是分別獨立進行。

主要結論

研究納入一個以38名患有慢性氣喘的患者為對向、且研究方法品質良好的試驗。相對於對照組來說,主動治療組的第一秒用力吐氣量(FEV1)和用力呼吸量(FVC)有明顯的增加;此外,目前並沒有數據顯示介入治療會產生嚴重的副作用。

作者結論

目前評估飲食介入(Dietary interventions)作為眾多體重控制課程一部份的影響的證據非常少;雖然我們尚無法在藥物治療外建議病人同時接受飲食介入以作為氣喘的特殊處理,飲食介入作為減重計畫對特定病人確實有益。然而,針對一般的氣喘患者,飲食熱量控制對氣喘的徵兆或症狀所造成的影響尚未確定。

總結

目前能證明降低熱量的攝取能改善氣喘的證據十分有限,還需進行更進一步的研究。一般認為,高熱量飲食可能會使得氣喘發作;理論上,降低飲食所攝取的熱量能緩和氣喘症狀。由於這篇文獻回顧的研究對象數目不足、研究中納入具有肥胖特性氣喘患者,而限制其研究結果;對於飲食控制對氣喘的影響,目前沒有一個強而有力結論,仍需更多的研究來證實。
