Asian American immigrants' risk of heart disease, diabetes, and obesity increase with duration of residence in the United States (US). Regular physical activity reduces the risk of these diseases, yet little is known about physical activity in Asian Americans and how it changes after immigration.
Data from the 2001 California Health Interview Survey, which oversampled Asian Americans, were analyzed to investigate the effects of ethnicity, nativity, and years in the US on leisure time physical activity (LTPA), non-leisure time physical activity (NLTPA), and occupational physical activity. A total of 4226 Asian Americans and 29,473 US-born non-Asians were included.
Asian Americans were much less likely to meet recommended levels of LTPA than US-born non-Asians (odds ratio [OR], men=0.51, 95% confidence interval [CI], 0.42, 0.61, OR, women = 0.48, 95% CI, 0.40, 0.57). Foreign-born Asians were least likely to participate in LTPA; LTPA increased as years in the US increased. After accounting for NLTPA, Asian Americans had significantly lower estimated weekly energy expenditure than US-born non-Asians.
Asian Americans, especially immigrants, are at risk for low levels of LTPA and high levels of physical inactivity. NLTPA does not offset these lower levels of LTPA. Increasing physical activity is key to protecting the health of this rapidly growing population.
亚裔美国移民患心脏病、糖尿病和肥胖症的风险会随着在美国的居住时间增加而上升。定期进行体育锻炼可降低患这些疾病的风险，但对于亚裔美国人的体育锻炼情况以及移民后其体育锻炼情况如何变化，我们却知之甚少。
对2001年加利福尼亚健康访谈调查的数据进行分析，该调查对亚裔美国人进行了过度抽样，以研究种族、出生地和在美国居住年限对休闲时间体育活动（LTPA）、非休闲时间体育活动（NLTPA）和职业体育活动的影响。总共纳入了4226名亚裔美国人和29473名在美国出生的非亚裔。
与在美国出生的非亚裔相比，亚裔美国人达到LTPA推荐水平的可能性要低得多（优势比[OR]，男性=0.51，95%置信区间[CI]，0.42，0.61；OR，女性=0.48，95%CI，0.40，0.57）。外国出生的亚裔参与LTPA的可能性最小；随着在美国居住年限的增加，LTPA参与度也随之提高。在考虑了NLTPA之后，亚裔美国人估计的每周能量消耗明显低于在美国出生的非亚裔。
亚裔美国人，尤其是移民，面临着LTPA水平较低和身体活动不足程度较高的风险。NLTPA并不能弥补LTPA的较低水平。增加体育活动是保护这一快速增长人群健康的关键。
