One of the goals of Healthy People 2020 is to increase physical activity (PA) and reduce health disparities among different racial and ethnic segments of the U.S. population. Few studies have been conducted to examine PA differences by birthplace and sex in youth of Mexican heritage.
Participants were 101 youth (43 boys, 58 girls, 59% U.S.-born, 41% Mexico-born) who wore a sealed New Lifestyles NL-1000 pedometer for 7 consecutive days.
Mexico-born youth took more steps, on average, than their U.S.-born counterparts (P = .038). However, moderate-to-vigorous intensity (MVI) time did not differ between Mexico- and U.S.-born youth (P = .146). By contrast to birthplace, sex-related differences were more consistent, as boys took more steps (P = .005) and accumulated more MVI time (P = .043) than girls. Only 4% of our sample met either one or both of the PA recommendations.
We conclude that PA may differ by birthplace and by sex in youth of Mexican heritage, as U.S.-born girls were the least active segment of our sample. Culturally sensitive interventions to increase daily PA must become a higher public health priority for youth of Mexican heritage, in particular, for U.S.-born girls of Mexican heritage.
《健康人民 2020》的目标之一是增加身体活动（PA）并减少美国不同种族和族裔群体之间的健康差异。很少有研究检查过具有墨西哥血统的青年的出生地和性别对 PA 的影响。
参与者为 101 名青年（43 名男孩，58 名女孩，59%为美国出生，41%为墨西哥出生），他们连续 7 天佩戴密封的 New Lifestyles NL-1000 计步器。
墨西哥出生的青年平均比美国出生的同龄人多走几步（P=0.038）。然而，中等到剧烈强度（MVI）时间在墨西哥和美国出生的青年之间没有差异（P=0.146）。与出生地不同，性别相关的差异更为一致，因为男孩比女孩走的步数更多（P=0.005），积累的 MVI 时间也更多（P=0.043）。我们的样本中只有 4%的人符合一项或两项 PA 建议。
我们得出结论，PA 可能因出生地和性别而异，具有墨西哥血统的美国出生女孩是我们样本中最不活跃的群体。增加日常 PA 的文化敏感干预措施必须成为具有墨西哥血统的青年，特别是具有墨西哥血统的美国出生女孩的更高公共卫生优先事项。
