Cardiac rehabilitation: health characteristics and socio-economic status among those who do not attend.

BACKGROUND: Cardiac rehabilitation (CR) is well documented, in randomised trials, to reduce mortality risk after myocardial infarction (MI). Selection of healthy patients for CR is a relatively unexplored problem. Our aims were to identify predictors of CR-attendance and to describe the prognosis as concerns mortality, re-admission and invasive treatment among CR-attendees as compared to CR-non-attendees. METHODS: From a cohort of 138 290 persons aged 30-69 years, we identified consecutive MI patients, between 1 April 2000 and 31 March 2002. There were 206 MI patients, who survived until admission, and among the 200 who survived 30 days, 145 (72.5%) attended a comprehensive CR programme. Data were obtained from patient charts and from Danish population registers, and as a result we had no non-participation for the study. RESULTS: The 2-year mortality proportions for patients surviving the first 30 days of admission were 2.8 and 21.8% among CR-attendees and CR-non-attendees, respectively (P < 0.0001). Among CR-non-attendees, there was a smaller fraction having an invasive treatment performed as compared with CR-attendees. By multiple logistic regression controlling for age and sex, CR-attendance was associated with chest pain, whereas CR-non-attendance was associated with low gross income, single living and inverted T-wave in the electrocardiogram. CONCLUSION: CR attendance rate was 72.5%. Non-attendees have a higher mortality risk, which in part may be attributed to selection of healthy patients. Non-attendees are older and more likely to have atypical symptoms at admission, a low socioeconomic status and to live alone. Special attention is needed to improve CR attendance among such patients.

Correlates of falling during 24 h among elderly Danish community residents.

OBJECTIVES: To identify dietary, medical, and environmental correlates of falling during the last 24 h among elderly community residents. The limited accuracy of recall of falls in the elderly in previous studies was the reason for a 24-h time frame. METHODS: The study composes 4281 community residents aged 66+ years. The statistical analyses included Pearson's chi(2) test and multiple logistic regression. RESULTS: Mutually independent correlates of falls were a family history of fracture (OR, 3.0; 95% CI: 1.3-7.1); osteoarthrosis of the knee (OR, 2.9; 95% CI: 1.3-6.2); dizziness (OR, 4.1; 95% CI: 1.9-8.9); a diet not including sour dairy products (OR, 3.0; 95% CI: 1.4-6.3) or fish (OR, 3.4; 95% CI: 1.5-7.5); drinking tea (OR, 5.8; 95% CI 2.15-15.30); needing help for shopping (OR, 3.9; 95% CI: 1.6-9.3); and for administration of medicine (OR, 9.0; 95% CI: 2.0-40.6). Independent environmental correlates were vinyl on the floor in the bathroom (OR, 6.6; 95% CI: 2.1-20.9) and using indoor footwear without soles (OR, 5.5; 95% CI: 2.3-13.4). CONCLUSION: The present analyses suggest that several factors are associated to the risk of falling among elderly community residents. It appears relevant for further studies to test if modifications of the potential risk factors identified may reduce falls among community dwelling older persons.

Proceedings of the National Institute of Diabetes and Digestive and Kidney Diseases International Symposium on Epidemiologic Issues in Urinary Incontinence in Women.

The Epidemiologic Issues in Urinary Incontinence: Current Databases and Future Collaborations Symposium included an international group of 29 investigators from 10 countries. The purpose of the symposium was to discuss the current understanding and knowledge gaps of prevalence, incidence, associated risk factors, and treatment outcomes for incontinence in women. During the symposium, investigators identified existing large databases and ongoing studies that provide substantive information on specific incontinence research questions. The investigators were able to form an international collaborative research working group and identify potential collaborative projects to further research on the epidemiology of urinary incontinence and bladder dysfunction.
