体重过轻对哮喘控制的影响
2012/11/09
摘要
背景:虽然对于哮喘控制与体重指数(BMI)的关系已经进行广泛研究,但大部分试验均关注BMI对哮喘发病率或肥胖对哮喘控制的影响。到目前为止,尚未有试验研究体重过低对哮喘控制的影响。
方法:本试验研究体重过低(基于日本肥胖研究协会[JASSO]的定义确定)对日本哮喘患者哮喘控制的影响。日本新泻哮喘治疗研究组通过问卷调查获取数据,比较正常体重组(18.5 kg/m2 ≤ BMI < 25 kg/m2)和低体重组(BMI < 18.5 kg/m2)的哮喘控制情况(基于哮喘控制测试[ACT]确定)。
结果:2008年和2010年间完成问卷调查的哮喘患者中,分别有1464名和1260名受试者分入正常体重组,分别有174名和155名受试者分入低体重组。低体重组的ACT评分,在2008年(22, [19-24])和2010年(23, [19-25])均显著低于正常体重组(分别为23, [20-25]和24, [21-25])。
结论:本试验为首次对低体重对哮喘的影响进行大规模的研究。结果显示,体重过低对哮喘控制会产生不良影响。但具体机制尚不清楚,有必要进一步研究。

Abstract
BACKGROUND: Although the association between asthma control and body mass index (BMI) has been thoroughly investigated, most of this work has focused on the influence on asthma incidence or the effect of obesity on asthma control. To date, there have been no published studies on the influence of underweight on asthma control.
METHODS: The aim of this study was to investigate the influence of underweight, as defined by the Japan Society for the Study of Obesity (JASSO), on asthma control in Japanese asthmatic patients. Using data from questionnaire surveys administered by the Niigata Asthma Treatment Study Group, we compared asthma control, as measured by the Asthma Control Test (ACT), between a normal weight group (18.5 kg/m2 =< BMI < 25 kg/m2) and an underweight group (BMI < 18.5 kg/m2).
RESULTS: Of the asthmatic patients who completed the 2008 and 2010 surveys, 1464 and 1260 cases were classified as being in the normal weight group, and 174 and 155 cases were classified as being in the underweight group. The ACT score (median, [interquartile range]) in the underweight group in 2008 (22, [19-24]) and 2010 (23, [19-25]) was significantly lower than that in the normal group in 2008 (23, [20-25]) and in 2010 (24, [21-25]).
CONCLUSIONS: This study is the first, large-scale investigation of the influence of underweight on asthma control, and we have confirmed an adverse influence in a clinical setting. A potential mechanism for this interaction was unknown. Further investigation will be required.
