Physical Activity and Risk of Atrial Fibrillation: A Nationwide Cohort Study in General Population

Abstract Although exercise prevents cardiovascular disease and mortality, vigorous exercise and endurance athletics can cause atrial fibrillation (AF). However, no large cohort study has assessed the relationship between physical activity and AF in the general population. We assessed the effect of physical activity at different energy expenditures on the incidence of AF. We studied 501,690 individuals without pre-existing AF (mean age, 47.6 ± 14.3 years; 250,664 women [50.0%]) included in the Korean National Health Insurance Service database. The physical activity level was assessed using a standardized self-reported questionnaire at baseline. During a median follow-up of 4 years, 3,443 participants (1,432 women [41.6%]) developed AF. The overall incidence of AF at follow-up was 1.79 per 1,000 person-years. The subjects who met the recommended physical activity level (500–1,000 metabolic equivalent task [MET] minutes/week) had a 12% decreased AF risk (adjusted hazard ratio [HR]: 0.88, 95% confidence interval [CI]: 0.80–0.97), but not the insufficiently (1–500 MET-minutes/week; HR: 0.94, 95% CI: 0.86–1.03) and highly active subjects (≥1,000 MET-minutes/week; HR: 0.93, 95% CI: 0.85–1.03). The recommended minimum key target range of physical activity level was associated with the maximum benefit for reduced AF risk in the general population. The dose-response relationship between physical activity level and AF risk showed a U-shaped pattern. Although exceeding the key target range attenuated this benefit, it did not increase the AF risk beyond that during inactivity.

Background:Exercise is becoming an important component of cancer rehabilitation programs. A consistent finding across studies is that patients experience improved physical fitness and reduced fatigue. However, sustained physical activity is essential if the benefits are to be preserved over the course of cancer survivorship.Objective:This study examined self-reported short-term exercise adherence following a 6-week, supervised exercise program (muscle strength, cardiovascular fitness, relaxation, body awareness, and massage) in a heterogeneous group of 61 cancer patients (mean age 42.9 years, 82% oncological and 18% haematological) from the Body & Cancer Project.Methods:Semistructured interviews were used to quantitatively assess leisure time physical activity level 1 and 3 months after completion of the program. The study furthermore included 3-month follow-up assessment of psychological distress (Hospital Anxiety and Depression Scale—HADS). Patient statements were selected that best illustrated trends found in the statistical material.Results:There was a significant postprogram reduction in physical activity from 6 to 10 weeks and from 6 to 18 weeks. However, the patients (half of whom were still undergoing treatment at the time of follow-up) reported a higher physical activity level postprogram compared to their baseline levels. The analyses showed a positive association between the 3-month postprogram physical activity level and pre-illness physical activity level, treatment, and postprogram changes in depression.Significance of research:Given the significant decrease in postprogram PA level, especially in subjects still undergoing cancer treatment, the study suggests that continuous supervised programs may be required in order to encourage and support exercise adherence in this population. However, randomized clinical controlled trials and more follow-up studies are needed to establish the optimal program length and content for sustained exercise adherence in cancer patients.

Physical Functions

Background: The preservation of physical functions such as muscle strength, balance and mobility is fundamental to maintaining independence in activities of daily living (ADL). The physical activity level of most nursing home residents is very low, which implies that they are often subject to a decline in health, mobility, autonomy and social contacts and are also at risk of suffering a decline in mental well-being. In a previous study, we demonstrated that transfers, balance and physical activity level improved after 3 months of individually tailored intervention in nursing home residents. Objective: To evaluate the long-term effects on ADL, balance function, physical activity level, physical performance, falls-related self-efficacy, well-being and cognitive function 3 months after the completion of our intervention in nursing home residents. Methods: The study was a multicenter randomized, controlled clinical trial with a parallel-group design. It was conducted in nursing homes in Sweden, Norway and Denmark, with an intervention period lasting 3 months and a follow-up at 6 months. Initially, 322 nursing home residents with a mean age of 85 years were included; 85 from Sweden, 171 from Norway and 66 from Denmark. Of these, 241 [129 intervention group (IG), 112 control group (CG)] were eligible for the 6-month follow-up tests. The level of dependence in ADL, physical activity level, several dimensions of physical function, well-being, falls-related self-efficacy and cognitive function were assessed with reliable and valid instruments at baseline, immediately after 3 months of intervention and 3 months later at the 6-month follow-up. Results: After 3 months of intervention and an additional period of 3 months without intervention, only the following 2 variables demonstrated significant group differences: social and cognitive function, measured by the Functional Independence Measure n-r, where the IG deteriorated while the CG was almost stable. However, regarding transfers, the IG deteriorated significantly less than the CG. Conclusion: Without supervised physical exercise that challenged the individuals' capability, gains in ADL function, balance and transfer ability deteriorated during the 3 months following the intervention period. Thus, continuous, individually adjusted and supported physical activity seems crucial for the maintenance of physical functions in these vulnerable elderly persons.
