女性儿童期肥胖预示成年哮喘发作:一项为期25年的前瞻性研究
2007/04/13
为了阐明儿童期肥胖与未来哮喘发病之间的联系,Burgess等调查了儿童期肥胖与青少年/成人后哮喘发病率之间的关系。
作者对一组未患哮喘的7岁儿童进行了长达25年以人群为基础的队列研究,即Tasmanian哮喘调查。入选时(7岁时)测定研究对象的体重、身高,并进行肺功能检查和哮喘状态的问卷调查,25年后(32 岁时)进行哮喘状态的问卷调查。以优势比表示肥胖和哮喘发病之间的联系。研究发现,在女性人群中, 成年哮喘(21岁后发病,32岁仍存在的哮喘)与7岁时的肥胖程度有明显的相关性,而且这种相关性不能以儿童肺功能或初潮年龄的差异来解释。但无论男女,既往哮喘(7岁后发病但32岁前痊愈的哮喘)与7岁时的肥胖程度与无关。
作者认为:在非哮喘女性儿童中,7岁时体重指数超标预示其存在成年后存在发生哮喘的风险。

Childhood adiposity predicts adult-onset current asthma in females: a 25-yr prospective study
Few data exist on associations between childhood adiposity and incident asthma in later life. The present authors examined the relationship between childhood body mass index (BMI) and incident asthma beginning in adolescence or in adult life.
All subjects included in the study were participants in the Tasmanian Asthma Survey, a large population-based cohort study, and were asthma free at 7 yrs of age. Weight, height and lung function were measured at 7 yrs of age. Asthma status at 7 and 32 yrs of age was ascertained by questionnaire. Odds ratios were calculated for the association between childhood adiposity, expressed as ’overweight’ or as BMI z-score quartiles at 7 yrs of age, and asthma development after that age.
In females, but not in males, there was a significant association between adiposity at 7 yrs of age and current asthma at 32 yrs of age that developed after the age of 21 yrs. The association was not explained by childhood lung function or age at menarche. There was no association between adiposity at 7 yrs of age and asthma that developed after that age and remitted at 32 yrs of age in either sex.
Higher body mass index in nonasthmatic young females at 7 yrs of age predicts risk of current asthma developing in adult life. (Eur Respir J 2007 29: 668-675.)
