血清微量营养素浓度与小儿哮喘:PIAMA出生队列研究
2011/11/23
摘要
背景:研究显示,微量营养素对儿童期哮喘存在影响。到目前为止,有关证据主要来源于针对营养素摄取的横断面研究,而营养素摄取并不是一个准确的检测营养素状态的方法。本试验为横断面前瞻性研究,分析了血清锰、维生素D、硒和锌与儿童期(重度)哮喘、过敏症和支气管高反应性(BHR)间的关系。
方法:在哮喘和螨虫过敏的预防和发病率出生队列研究中,检测4岁儿童(n = 372)和8岁儿童(n = 328)的血清营养素含量。8岁前每年通过问卷调查评估哮喘患病情况。4岁和8岁时检测过敏性致敏;8岁时检测BHR。采用logistic回归和广义估计方程组模型对数据进行分析。
结果:血清锰含量与哮喘发病成负相关,但无显著性。4岁时血清维生素D含量与4~8岁时的哮喘成负相关(维生素D三分位数与严重哮喘的横断面相关性:OR:0.49;95%CI:0.25–0.95),而8岁时维生素D与8岁时的哮喘成正相关(维生素D三分位数与严重哮喘的横断面相关性:OR: 2.14;95% CI: 0.67–6.82)。
结论:我们研究显示,高血清锰水平的儿童,患哮喘风险较低。血清维生素D含量与哮喘的相关性存在年龄依赖性。

Abstract
BACKGROUND:Research suggests an influence of micronutrients on childhood asthma. So far, evidence mainly originates from cross-sectional studies using nutrient intake data, which is not an accurate measure of nutrient status. This study aimed to investigate the cross-sectional and prospective associations between serum concentrations of magnesium, vitamin D, selenium, and zinc and prevalence of (severe) asthma, atopy, and bronchial hyperresponsiveness (BHR) in childhood.
METHODS:In the Prevention and Incidence of Asthma and Mite Allergy birth cohort study, serum nutrient concentrations were available for a 4-yr-old subgroup (n = 372) and for a different 8-yr-old subgroup (n = 328). Yearly questionnaires inquired about asthma prevalence until 8 yr of age. Allergic sensitization was measured at 4 and 8 yr of age; BHR was measured at 8 yr of age. Data were analyzed with logistic regression and generalized estimating equations models.
RESULTS:There was a consistent (non-significant) inverse association between serum magnesium concentrations and asthma prevalence. Serum vitamin D concentrations measured at age 4 were inversely associated with asthma at ages 4–8 [e.g., cross-sectional association between vitamin D tertile 3 vs. 1 and severe asthma: odds ratio (OR): 0.49, 95% confidence interval (CI): 0.25–0.95], whereas vitamin D measured at age 8 was positively associated with asthma at age 8 (e.g., cross-sectional association between vitamin D tertile 3 vs. 1 and severe asthma: OR: 2.14, 95% CI: 0.67–6.82).
CONCLUSIONS:Our study contributes to the evidence that children with higher serum magnesium concentrations are less likely to have asthma. The associations between serum vitamin D concentrations and asthma were age-dependent.
