Obesity and overweight have been described as factors associated with asthma. Our aim was to evaluate the role obesity plays on asthma in children. SCOPE AND SUBJECTs: A study carried out on children and teenagers between 8 and 15 years of age, chosen for a cluster-type random sampling from children who studied in 80 schools, which represents 30% of the schools in the city of Valencia.
The analysed data was organized into two groups, obese (from the Body Mass Index (Kg/m2)), showing children with a percentile over 85% of the measuring reference for the Spanish population) and non obese, when they did not fulfil this condition. The prevalence of the different parameters studied was calculated by an Interval of Confidence of 95%. The risk was calculated (Relative Risk) from those symptoms compatible with asthma among obese children compared to non obese children.
No significant relative risk (RR) was seen for obesity with regards to asthma in those percentiles of obesity over 85. Otherwise, an increase in the relative risk (RR) regarding the severity of asthma was seen in relation to obesity, mainly in the 85th percentile (RR = 1.51 of suffering between 4-12 wheezing attacks and RR = 1.86 of suffering more than 12 attacks in obese children as opposed to non obese children).
In this study, we did not identify a higher risk of asthma among obese children than among non obese children, although we did find there was a higher risk of severity of asthmatic symptoms. As far as the severity of the asthma is concerned, we saw a higher risk of wheezing and whistling attacks among obese children with the 85th and the 95th percentiles according to the Body Mass Index.
肥胖和超重被认为是与哮喘相关的因素。我们的目的是评估肥胖在儿童哮喘中所起的作用。
对8至15岁的儿童和青少年进行了一项研究，通过整群随机抽样从瓦伦西亚市80所学校就读的儿童中选取，这些学校占该市学校总数的30%。
将分析的数据分为两组，肥胖组（根据体重指数（千克/平方米），即百分位数超过西班牙人群测量参考值85%的儿童）和非肥胖组（不符合此条件的儿童）。所研究的不同参数的患病率通过95%的置信区间计算。计算肥胖儿童与非肥胖儿童中与哮喘相符的症状的风险（相对风险）。
在肥胖百分位数超过85的情况下，未发现肥胖与哮喘之间存在显著的相对风险（RR）。否则，与肥胖相关的哮喘严重程度的相对风险（RR）有所增加，主要在第85百分位数（肥胖儿童与非肥胖儿童相比，4至12次喘息发作的RR = 1.51，超过12次发作的RR = 1.86）。
在本研究中，我们未发现肥胖儿童患哮喘的风险高于非肥胖儿童，尽管我们确实发现哮喘症状严重程度的风险更高。就哮喘的严重程度而言，根据体重指数，我们发现第85和第95百分位数的肥胖儿童喘息和哮鸣发作的风险更高。
