The article reports on the stratification of grip strength value by age, gender, and chronic disease status in adults aged 50 years and older. Topics discussed include grip strength, multimorbidity, and population-based values. Also being discussed include impact of single chronic diseases like coronary heart disease, stroke, and chronic obstructive pulmonary disease.

Local health departments (LHDs) can play a major role in partnering with faith-based organizations to enhance the overall health status of the public. This study examines the frequency that LHDs and faith-based partnerships occur, types of activities performed as reported by LHDs, and population and functional characteristics associated with these partnerships. Secondary data analysis of the 2005 National Profile of LHDs study (Profile), developed by the National Association of County & City Health Officials, was conducted on a stratified random sample of 517 LHDs receiving the core questionnaire and a module with questions about partnership and collaboration. Results indicated that 361 LHDs (83.1%) reported partnership activities occurring with faith-based organizations. At least one partnership activity was performed, with the overall most commonly reported activity as exchanging information (66.6%) across small, medium, and large LHDs. Size of jurisdiction, was positively associated with any partnership activity, higher median number of partnership activities, and higher percentage of high-level partnerships (ie providing financial resources or taking the leadership role). Further studies should consider types of programs and services produced by LHDs and faith-based partnerships, additional factors that impact partnership activities, and differences in partnership activities existing by racial and ethnic characteristics of LHD jurisdictions.

Purpose: The purpose of the present pilot study was to provide a preliminary estimate of the minimum detectable difference (MDD) and minimum clinically important difference (MCID) of the six-minute walk test (6MWT) and daily activity in outpatients with chronic heart failure (CHF)., Methods: A convenience sample of 22 adults with stable New York Heart Association Functional Class II and III CHF performed two baseline 6MWTs separated by 30 minutes of rest. Subjects then wore a triaxial accelerometer for 7 days to monitor daily activity. After 7 weeks of usual care, subjects again wore the accelerometer for 7 days and then returned to the clinic to complete the Global Rating of Change Scale (GRS) with regard to their heart disease and perform another set of 6MWTs. For the 6MWT, the MDD was calculated using the two baseline 6MWT distances. For daily activity, the MDD was calculated using two methods: (1) day-to-day test-retest reliability during baseline monitoring, and (2) baseline to follow-up test-retest reliability in those who reported no change on the GRS. The MCID for the 6MWT and daily activity was calculated using the mean and 95% confidence interval (CI95%) for those subjects who reported 'improvement' on the GRS., Results: The MDD at the CI95% for the 6MWT was 32.4 meters. The MCID for the 6MWT was 30.1 (CI95% 20.8, 39.4) meters. The MDD for daily activity was 5,909 vector magnitude units (VMU·hr.(-1)) The MCID for daily activity was 1,337 VMU·hr.(-1) There was good alignment of the MDD and MCID for the 6MWT, suggesting that clinically meaningful change is approximately 32 meters. However, the calculated MCID was substantially less than measurement error as represented by the MDD, indicating that the MCID was underestimated in this sample or that daily activity may be robust to change in overall disease status.

Purpose: The purpose of the present review was to use existing, published data to provide an estimate of the amount of change in six-minute walk test distance (Δ6MWT) that represents a clinically meaningful change in individuals with chronic heart failure (CHF)., Methods: THE PRESENT REVIEW INCLUDED TWO SEPARATE LITERATURE SEARCHES OF THE CINAHL AND MEDLINE DATABASES FOR ARTICLES THAT: (1) reported the intraclass correlation coefficient (ICC) of the 6MWT in individuals with CHF, and (2) used the 6MWT along with either aerobic capacity or health-related quality of life (HRQL) as study endpoints in randomized controlled trials (RCTs) of exercise-based intervention for individuals with CHF. The ICCs were used to calculate the minimum detectable difference (MDD) at the 95% confidence interval for each included study. The Δ6MWT associated with aerobic capacity and HRQL within-group effect sizes for the intervention and control groups in each included RCT was analyzed using receiver operating characteristic (ROC) curves., Results: Thirteen articles reported the ICC for the 6MWT. The mean (standard deviation) MDD calculated based on these data was 43.1(16.8) m. Eighteen RCTs measured the 6MWT and either aerobic capacity and/or HRQL. A Δ6MWT of 40-45 m was associated with at least moderate aerobic capacity and HRQL effect sizes in the intervention groups. The Δ6MWT thresholds that discriminated between intervention and control groups using ROC curves revealed the following sensitivity/specificity for the respective thresholds: 19 m, 94.4/83.3%, 32 m, 83.3/94.4%, and 48 m 44.4/100% (AUC = .935, p = .009, CI(95%) .855, 1.015)., Conclusions: A Δ6MWT of approximately 45 m appears to exceed measurement error and be associated with significant changes in either aerobic capacity and/or HRQL.
