This single-group repeated-measures pilot study evaluated the effects of a 10-wk, multicomponent, best-practice exercise program on physical activity, performance of activities of daily living (ADLs), physical performance, and depression in community-dwelling older adults from low-income households (N = 15). Comparison of pretest and posttest scores using a one-tailed paired-samples t test showed improvement (p < .05) for 2 of 3 ADL domains on the Activity Measure-Post Acute Care and for 6 physical-performance measures of the Senior Fitness Test. Repeated-measures ANOVA revealed significant main effects for 3 of 8 physical activity measures using the Yale Physical Activity Scale. Retention rate was 78.9%, and the adherence rate for group sessions was 89.7%. Results suggest that participation in a multicomponent, best-practice physical activity program may positively affect sedentary, community-dwelling older adults' physical activity, ADL performance, and physical performance.  相似文献

In an age of telemarketers, spam emails, and pop-up advertisements, sociologists are finding it increasingly difficult to achieve high response rates for their surveys. Compounding these issues, the current political and social climate has decreased many survey respondents’ likelihood of responding to controversial questions, which are often at the heart of much research in the discipline. Here we discuss such implications for survey research in sociology using: a content analysis of the prevalence of missing data and survey research methods in the most cited articles in top sociology journals, a case study highlighting the extraction of meaningful information through an example of potential mechanisms driving the non-random missing data patterns in the Religion Among Academic Scientists dataset, and qualitative responses from non-responders in this same case. Implications are likely to increase in importance given the ubiquitous nature of survey research, missing data, and privacy concerns in sociological research.  相似文献

Using a multivariate framework, we analyze trends in employer provision of retiree health insurance (RHI), eligibility for new retirees, and retiree contributions. Data come for the Medical Expenditure Panel Survey—Insurance Component (MEPS-IC). While RHI provision to existing retirees decreased, eligibility for new retirees declined even more. Contribution requirements increased between 2000 and 2006 for retirees not yet eligible for Medicare (less than 65 years of age), but remained stable for those who were eligible (65 years of age or older). These results suggest growing financial instability for retirees.  相似文献

During 1998–2007, a majority of Central and Eastern European (CEE) governments enacted laws obligating workers to save for retirement in privately managed individual accounts. The governments funded these accounts with a portion of public pension revenues, thus creating or increasing deficits in public systems. After the onset of the global financial and economic crisis (2008), most CEE governments reduced these funding diversions and scaled back the accounts. Now, a decade after the crisis, this article examines the benefits that the accounts are beginning to pay retiring workers. In general, these benefits are shown to be disadvantageous compared with public pensions. Some pay lump sums in lieu of regular monthly benefits, most fail to adjust pensions regularly for inflation, and some pay women less than men with equal account balances. In several countries, pensioners with individual accounts receive lower benefits than those without them. To enable retiring workers to avoid these disadvantages, several CEE governments have allowed them to refund their account balances and receive full public pensions. Yet while this strategy diffuses worker dissatisfaction, it also places strains on public pension finance. To assist second‐pillar account holders without weakening public pensions, governments should consider making private pension savings voluntary and financing these schemes independently of public pensions – i.e. by worker and employer contributions and, possibly, direct state support.  相似文献
