title: Differences in Self-Reported Physical Activity and Body Mass Index Among Older Hispanic and Non-Hispanic White Men and Women: Findings from the 2009 California Health Interview Survey.
abstract: 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.
