Several studies suggest that physical activity may improve health-related quality of life. Other studies have shown that participation in physical activity differs among women of different racial/ethnic groups. This study aimed to determine whether the association between physical activity and health-related quality of life differs among women aged 40 to 64 years from different racial/ethnic groups.
We explored the association between physical activity level and health-related quality of life with descriptive statistics and multiple regression analyses adjusting for potential confounders among 11,887 women aged 40 to 64 years who identified themselves as Latinas, Asians, African Americans, or whites in the 2005 California Health Interview Survey.
Although white women reported more regular physical activity than women of other racial/ethnic groups, Asian women reported fewer mentally and overall unhealthy days than women of other groups. Nonetheless, as physical activity increased, health-related quality of life improved only among white women (fewer physically unhealthy, mentally unhealthy, recent activity limitation, and overall unhealthy days) and among Latinas (fewer overall unhealthy days).
Future studies should try to confirm if and clarify why the association between physical activity level and health-related quality of life differs among these middle-aged women of different races/ethnicities. If confirmed, this association would imply that health care professionals and those who design public health interventions may need to vary their promotion methods and messages to encourage physical activity among women of different races/ethnicities.

    ABSTRACT: We examined factors that influence health-related quality of life (HRQOL) among individuals aged 50 years and older with and without functional limitations. We analyzed data from the 2009 Behavioral Risk Factor Surveillance System to assess associations among demographic characteristics, health care access and utilization indicators, modifiable health behaviors, and HRQOL characterized by recent physically and mentally unhealthy days in those with and those without functional limitations. We defined functional limitations as activity limitations owing to physical, mental, or emotional health or as the need for special equipment because of health. Age, medical care costs, leisure-time physical activity, and smoking were strongly associated with both physically and mentally unhealthy days among those with functional limitations. Among those without functional limitations, the direction of the effects was similar, but the size of the effects was substantially smaller. The availability of lower cost medical care, increasing leisure-time physical activity, and reducing rates of cigarette smoking will improve population HRQOL among older adults with and without functional limitations. These factors provide valuable information for determining future public health priorities.

    ABSTRACT: Purpose: To evaluate the impact of race/ethnicity on the relationship between body mass index (BMI) and health-related quality of life (HRQOL) among blacks, Hispanics, and whites. Methods: We used the Sinai Urban Health Institute's Improving Community Health Survey dataset to measure physical and mental HRQOL using the Physical Component Score (PCS-12) and the Mental Component Score (MCS-12) of the Short Form-12. Multivariate linear regression models were applied to the overall sample and in models stratified by race/ethnicity to evaluate the effects of BMI on physical and mental HRQOL outcome variables while controlling for confounders. Results: Considering physical HRQOL, increasing BMI was independently associated with worse PCS-12 (β = -0.22, p value <0.001) in the overall sample; the magnitude was not significantly different across racial/ethnic subgroups (blacks: β = -0.18, p value = 0.02; Hispanics: β = -0.28, p value = 0.01; whites: β = -0.20, p value = 0.02). Overall, Hispanic participants reported a worse PCS-12 compared to whites (β = -3.06, p value = 0.002). Considering mental HRQOL, BMI was not significantly associated with MCS-12 in the overall sample (β = -0.06, p value = 0.21) nor was BMI significantly associated with MCS-12 in any racial/ethnic subgroups. Overall, black participants reported better MCS-12 compared to whites (β = 2.51, p value = 0.001). Conclusions: BMI was associated with worse physical HRQOL to a similar degree among blacks, Hispanics, and whites. This finding suggests that interventions leading to obesity reduction should be associated with substantial and equal improvements in the physical HRQOL of all race/ethnicity groups.

    ABSTRACT: Objective: To examine the prospective association of patterns of physical activity, sedentary behavior and sleep with health-related quality of life (HRQL) in the general population of Spain. Methods: A cohort study with 4271 individuals aged ≥ 18 years was recruited in 2008-2010 and followed-up prospectively through 2012. Activity patterns were derived from factor analysis. HRQL was assessed with the SF-12 questionnaire, and suboptimal HRQL was defined as a score below the sex-specific sample median. Results: Three main activity patterns were identified. A higher adherence to the pattern named "vigorous activity-seated at the computer" was inversely associated with a suboptimal score in the physical-composite summary (PCS) of the SF-12 (multivariate adjusted odds ratio [aOR] for the highest vs. the lowest quartile 0.71; 95% confidence interval [IC] 0.55-0.90; p-trend=0.003). The "light activity-seated for reading" pattern was inversely associated with a suboptimal score in the mental-composite summary (aOR=0.73; 95% CI=0.61-0.89; p-trend=0.002). However, a higher adherence to the "seated for watching TV-daytime sleeping" pattern was directly associated with suboptimal PCS (aOR=1.35; 95% CI=1.10-1.66; p-trend=0.008). Conclusion: Patterns including any physical activity were associated with better physical or mental HRQL. However, a pattern defined by sedentary behavior with diurnal sleep showed worse HRQL and should be a priority target of preventive interventions.
