Age and race impact the association between BMI and CVD mortality in women.
Journal - Public health reports (Washington, D.C. : 1974) (United States )
OBJECTIVES: In previous studies, we have shown that obesity is associated with increased cardiovascular disease (CVD) mortality in white women but not in black women. Earlier research suggests that body mass index (BMI) has a greater effect on CVD mortality in younger white females than older white females, whereas this relationship in black women is not as clear. This study examines the effect of age on the association of BMI to CVD in black and white women. METHODS: The Black Pooling Project includes data on 2,843 black women with 50,464 person-years of follow-up, and 12,739 white women with 214,606 person-years of follow-up. A Cox proportional hazards model was used to examine the association between BMI and CVD mortality for specific age/race groups. The younger group was < 60 years of age and the older group was > 60 years of age. RESULTS: In younger white women, the relative risk (95% confidence interval [CI]) for CVD mortality was significant in obese women (BMI > 30 kg/m2) vs. women of normal weight (BMI 18.5-24.9 kg/m2) (1.59 [CI 1.20, 2.09]). Similarly, in older white women, the relative risk for CVD mortality in obese women vs. women of normal weight was significant (1.21 [CI 1.04, 1.41]). There were no such associations for black women. Overweight (BMI 25-29.9 kg/m2) was not associated with increased risk in black or white women. CONCLUSION: These findings indicate that obesity is associated with a significantly greater risk of CVD mortality among white women, with the strongest association among white women < 60 years of age.

Differences in cardiovascular disease mortality associated with body mass between Black and White persons.
Journal - American journal of public health (United States )
We analyzed cardiovascular disease mortality risks associated with obesity using participant-level meta-analysis of data from the Black Pooling Project for Black and White individuals. The adjusted relative risks (ARRs) were stronger among White participants than among Black participants for coronary heart disease AAR=1.21 (95% confidence interval [CI]=1.07, 1.36) versus 0.87 (95% CI=0.69, 1.09), respectively, and cardiovascular disease ARR=1.18 (95% CI=1.07, 1.29) versus 0.91 (95% CI=0.77, 1.05), respectively. The results suggest that obesity is an independent risk factor in White people, and additional study of body size and disease progression is necessary in the assessment of racial disparities.

Physical activity and health related quality of life among people with arthritis.
Journal - Journal of epidemiology and community health (England )
STUDY OBJECTIVE: To assess the association between physical activity and health related quality of life (HRQOL) among persons with arthritis or chronic joint symptoms (CJS). DESIGN: Cross sectional survey investigating the relation between physical activity level and HRQOL. HRQOL was estimated using the number of physically or mentally unhealthy days during the past 30 days. Physical activity was categorised as recommended, insufficient, or inactive according to federal activity recommendations. Persons with arthritis were defined as those with either self reported CJS or doctor diagnosed arthritis. SETTING: Community dwelling, US adults residing in all 50 states and the District of Columbia. PARTICIPANTS: Respondents (n = 212 000) in the 2001 behavioral risk factor surveillance system (BRFSS), an annual population based, telephone survey. MAIN RESULTS: The 33% of BRFSS respondents with arthritis had a mean of 6.7 physically and 4.9 mentally unhealthy days during the past 30 days, compared with 1.8 and 2.7 among those without arthritis. Inactive men and women were 1.2-2.4 times more likely to report impaired HRQOL compared with those who met physical activity recommendations. Men and women who engage in insufficient physical activity also report variably reduced HRQOL. CONCLUSIONS: Among people with arthritis, recommended levels of physical activity were associated with fewer mean physically and mentally unhealthy days and a decreased probability of having severely impaired physical or mental HRQOL.

Prevalence and impact of arthritis among nursing home residents.
Journal - Annals of the rheumatic diseases (England )
OBJECTIVE: To determine the prevalence, characteristics, and impact of arthritis in the US nursing home population. METHODS: A national cross sectional sample of US nursing homes (8138 sampled residents in 1406 nursing homes) from the 1997 National Nursing Home Survey provided demographic and functional characteristics for residents with primary arthritis, any arthritis, or no arthritis diagnosis at admission. RESULTS: Of the estimated 1.6 million current nursing home residents in 1997, only 43,000 (3%) had a primary and 300,000 (19%) had any arthritis diagnosis at admission. People with a primary or any arthritis diagnosis received physical/occupational therapy, used wheelchairs and walking aids, and needed assistance with walking and transferring more often than those with no arthritis diagnosis. CONCLUSIONS: These national estimates suggest that arthritis is underreported in nursing home residents. Because arthritis contributes to an increased physical burden on staff and decreased functional capability of residents, both staff and residents can benefit from better diagnosis, intervention, and education.
