Mexican Americans have lower rates of asthma than other ethnic groups in the United States.
To examine the relationship between country of birth and acculturation with asthma and wheezing among Mexican American youths.
We used Chi-squared statistics and logistic regression analyses to determine the associations of country of birth and acculturation with asthma and wheezing among 1,770 Mexican Americans age 12-19 years who participated in the National Health and Nutrition Examination Survey 1999-2002.
Mexican American adolescents born in the United States and those with high acculturation levels reported significantly higher prevalence rates of asthma, wheezing, and hay fever than their peers with low acculturation levels and born in Mexico. In multivariate analyses, youths with a high acculturation level had a higher risk of asthma than those with a low acculturation level independent of country of birth. Highly acculturated youths born in the US had a higher risk for wheezing compared with less acculturated US-born or Mexico-born participants after adjusting for confounding variables. In contrast, associations of asthma and wheezing with country of birth were not significant after controlling for acculturation. CONCLUSIONS. Our findings showed that both acculturation and country of birth were linked with the risk of asthma and wheezing, with acculturation having stronger effects than country of birth, among Mexican American youths. These findings may imply that factors modified by immigration and acculturation could influence the risk of asthma and wheezing. Identification of such factors could help in the design of asthma prevention programs.
在美国，墨西哥裔美国人的哮喘发病率低于其他种族群体。
研究墨西哥裔美国青少年的出生国和文化适应程度与哮喘及喘息之间的关系。
我们运用卡方统计和逻辑回归分析，以确定1999 - 2002年参加国家健康与营养检查调查的1770名12 - 19岁墨西哥裔美国人中，出生国和文化适应程度与哮喘及喘息之间的关联。
在美国出生的墨西哥裔美国青少年以及文化适应程度高的青少年，其哮喘、喘息和花粉热的患病率显著高于文化适应程度低且出生在墨西哥的同龄人。在多变量分析中，文化适应程度高的青少年患哮喘的风险高于文化适应程度低的青少年，且与出生国无关。在调整混杂变量后，与文化适应程度较低的美国出生或墨西哥出生的参与者相比，在美国出生且文化适应程度高的青少年喘息风险更高。相比之下，在控制文化适应程度后，哮喘和喘息与出生国的关联并不显著。结论。我们的研究结果表明，在墨西哥裔美国青少年中，文化适应程度和出生国都与哮喘和喘息风险相关，其中文化适应程度的影响比出生国更强。这些发现可能意味着移民和文化适应所改变的因素会影响哮喘和喘息的风险。识别这些因素有助于设计哮喘预防项目。
