Evidence suggests that Latina women appear to be less physically active than women of other racial/ethnic groups. This study evaluated how different domains of physical activity (PA) contributed to overall levels of PA among low-income Latinas, the validity of Latinas' self-reported PA, and potential moderators of self-report bias in PA.
A community sample of 105 Latinas (mean age = 35.9 ± 9.0 years; mean body mass index = 31.6 ± 7.2) completed the long form Spanish-language version of the International Physical Activity Questionnaire (IPAQ), wore an accelerometer for seven days, and completed self-reported measures of acculturation and socioeconomic status.
Ninety-six percent of IPAQ-reported moderate-intensity PA (MPA) was accrued during household activities, with only 4% accrued during leisure time. Seventy-two percent of participants met national recommendations for PA using IPAQ data, but only 20% met recommendations when measured by accelerometer. When bouts of MPA lasting >10 min were included, 0% met recommendations. Age appeared to moderate self-report bias of vigorous PA, and there were nonsignificant trends for acculturation and income to moderate MPA and vigorous-intensity PA, respectively.
Data suggest that it is important to measure household activity of Latinas, and that the IPAQ yield overestimates of self-report PA.
有证据表明，拉丁裔女性的身体活动水平似乎低于其他种族/族裔群体的女性。本研究评估了不同身体活动（PA）领域对低收入拉丁裔女性整体 PA 水平的贡献、拉丁裔女性自我报告 PA 的有效性，以及 PA 自我报告偏差的潜在调节因素。
对 105 名拉丁裔女性（平均年龄=35.9±9.0 岁；平均体重指数=31.6±7.2）进行了社区抽样，完成了国际体力活动问卷（IPAQ）的长格式西班牙语版本，佩戴加速度计 7 天，并完成了关于文化适应和社会经济地位的自我报告测量。
96%的 IPAQ 报告的中强度 PA（MPA）是在家庭活动中积累的，只有 4%是在闲暇时间积累的。72%的参与者根据 IPAQ 数据达到了 PA 的国家推荐标准，但只有 20%的参与者根据加速度计测量达到了推荐标准。当包括持续时间>10 分钟的 MPA 时，没有人达到推荐标准。年龄似乎调节了剧烈 PA 的自我报告偏差，文化适应和收入分别对 MPA 和剧烈强度 PA 的自我报告偏差有不显著的趋势调节作用。
数据表明，测量拉丁裔女性的家务活动很重要，并且 IPAQ 会高估自我报告的 PA。
