Older Hispanic Americans are a rapidly growing minority group who are disproportionately affected by diabetes mellitus and obesity. Given the importance of physical activity, particularly leisure-time activity, in the management of diabetes mellitus and obesity, the current study examined ethnic and sex differences in walking for transportation, leisure-time walking, moderate activity (not including walking), and vigorous activity between Hispanic and non-Hispanic white (NHW) older adults (age 55 and older) using the 2009 California Health Interview Survey, a population-based survey representative of California's noninstitutionalized population. The total sample consisted of 21,702 participants (20,148 NHW (7,968 men, 12,180 women) and 1,554 Hispanic (609 men, 945 women)). Multivariable logistic and linear regression analyses were adjusted for sociodemographic characteristics. The findings revealed that Hispanic men and women were significantly less likely to engage in self-reported leisure-time walking and vigorous activity than NHW men (adjusted odds ratio (aOR) = 0.71, 95% confidence interval (CI) = 0.51-0.99) and women (aOR = 0.60, 95% CI = 0.42-0.87). Regardless of ethnic group, men were more likely than women to engage in self-reported walking for transportation (aOR = 0.71, 95% CI = 0.58-0.87), moderate activity (aOR = 0.68, 95% CI = 0.57-0.81), and vigorous activity (aOR = 0.58, 95% CI = 0.50-0.68). All types of self-reported physical activity were associated with lower body mass index (BMI; P < .001), although significant interactions between sex and leisure time walking (P < .001), moderate activity (P < .001), and vigorous activity (P < .001) indicated that women who engaged in these activities reported the lowest BMIs. The findings highlight the importance of emphasizing walking in efforts to increase moderate and vigorous activity, particularly for older women.
年长的西班牙裔美国人是一个快速增长的少数群体，糖尿病和肥胖对他们的影响尤为严重。鉴于身体活动，特别是休闲时间的活动，在糖尿病和肥胖管理中的重要性，本研究利用2009年加利福尼亚健康访谈调查，对西班牙裔和非西班牙裔白人（NHW）的老年人（55岁及以上）在步行外出、休闲时间步行、适度活动（不包括步行）和剧烈活动方面的种族和性别差异进行了研究，该调查是一项基于人群的调查，代表了加利福尼亚州的非机构化人口。总样本包括21702名参与者（20148名NHW（7968名男性，12180名女性）和1554名西班牙裔（609名男性，945名女性））。多变量逻辑回归和线性回归分析对社会人口学特征进行了调整。研究结果显示，西班牙裔男性和女性进行自我报告的休闲时间步行和剧烈活动的可能性显著低于NHW男性（调整后的优势比（aOR）=0.71，95%置信区间（CI）=0.51-0.99）和女性（aOR = 0.60，95% CI = 0.42-0.87）。无论种族如何，男性进行自我报告的步行外出（aOR = 0.71，95% CI = 0.58-0.87）、适度活动（aOR = 0.68，95% CI = 0.57-0.81）和剧烈活动（aOR = 0.58，95% CI = 0.50-0.68）的可能性都高于女性。所有类型的自我报告身体活动都与较低的体重指数（BMI；P <.001）相关，尽管性别与休闲时间步行（P <.001）、适度活动（P <.001）和剧烈活动（P <.001）之间的显著交互作用表明，参与这些活动的女性报告的BMI最低。研究结果突出了强调步行对于增加适度和剧烈活动的重要性，特别是对于老年女性。
