Abstract

Background: Physical activity (PA) is associated with reduced mortality. However, whether there is an added benefit of long‐term endurance training is unclear. Thus, we aimed to examine 10‐year mortality in older male endurance athletes compared with an older male general population. Method: Male athletes (n = 503) participating in an annual long‐distance ski race (median years of participation: 14, range: 1–53) from the Norwegian Birkebeiner Aging study (BiAS), and non‐athletic men (n = 1867) attending the sixth Tromsø Study (Tromsø6) aged ≥65 years were included. Associations with endurance sport practice and joint exposures of endurance sport practice and self‐reported leisure‐time PA with all‐cause mortality were examined. We analyzed the data with Cox proportional hazard models and regression standardization. Results: After 10 years (median: 10.4, range: 0.5–11.1) the mortality rate was lower in athletes (hazard ratio (HR) 0.34, 95% confidence interval (CI): 0.24–0.49) compared with non‐athletes, corresponding to a 15% (95% CI: 12–19%) absolute risk reduction associated with endurance sport practice. In joint analyses categorized according to PA and endurance sport practice, we observed an inverse dose–response relationship with mortality (p < 0.001). Compared to inactive non‐athletes, PA was associated with lower mortality in both active non‐athletes and athletes. However, the observed benefit among participants reporting moderate‐to‐vigorous PA was larger in athletes (HR: 0.21, 95% CI: 0.14–0.32) than non‐athletes (HR: 0.43, 95% CI: 0.31–0.59) (p < 0.01). Conclusion: Endurance sport practice was associated with reduced 10‐year mortality, beyond the effect of PA in older men. This study suggests that long‐term endurance sport practice maintained into older adulthood promotes longevity. [ABSTRACT FROM AUTHOR]

Abstract

This study explores the risk for cancer by level of antibodies to the anaerobe oral bacteria of periodontitis Tannerella forsythia (TF), Porphyromonas gingivalis (PG), and Treponema denticola (TD) all three collectively termed the red complex, and the facultative anaerobe bacterium Aggregatibacter actinomycetemcomitans (AA). The prospective cohort, the Oslo II-study from 2000, the second screening of the Oslo study of 1972/73, has been followed for 17 ½ years with regard to cancer incidence and mortality. A random sample of 697 elderly men comprised the study cohort. The antibody results measured by enzyme linked immunosorbent assay (ELISA) were used in the Cox proportional hazards analyses, and quartile risk on cancer incidence in a 17 ½ years follow-up. Among the 621 participants with no prior cancer diagnoses, 221 men developed cancer. The incidence trend was inverse, and the results are shown as 1st quartile of highest value and 4th as lowest of antibody levels. The results of the Cox proportional regression analyses showed that TF inversely predicts bladder cancer (n = 22) by Hazard Ratio (HR) = 1.71 (95% CI: 1.12, 2.61). TD inversely predicts colon cancer (n = 26) by HR = 1.52 (95% CI: 1.06, 2.19) and bladder cancer (n = 22) by HR = 1.60 (95% CI: 1.05, 2.43). Antibodies to two oral bacteria, TF and TD, showed an inverse risk relationship with incidence of specific cancers: TF bladder cancer, TD bladder and colon cancer. Lowered immunological response to the oral infection, periodontitis, is shown to be a risk factor in terms of cancer aetiology. [ABSTRACT FROM AUTHOR]

Abstract

The aim of this study was to investigate possible differences in measures on disease process, joint damage, health status and self-efficacy between patients with rheumatoid arthritis (RA) living in an affluent and in a less affluent area in the same city. We analyzed data collected on patients enrolled in a community-based register of patients with RA in Oslo, Norway. 246 patients were examined by questionnaire in 1994 and 133 patients were examined clinically in 1997. Measures on disease process, joint damage, health status and self-efficacy were compared between patients from two residential areas. There was no significant difference regarding joint counts, patients' or investigator's evaluation of disease severity, blood test results and number of joint replacements. Significant differences were observed for disability and for various dimensions of health measured by the arthritis impact measurement scales and the short form-36: patients in the less affluent area reported poorer health status. Patients in this area also showed significantly lower scores on the arthritis self-efficacy scale. Patients with RA in two socioeconomically different areas in Oslo thus were found to be equal regarding disease process and joint damage measures. However, in the measures reflecting physical and psychosocial health status, patients in the less affluent area seemed to be more seriously ill. They also showed less confidence in their ability to influence the disease. Even in a welfare society with universal access to health care the impact of a well-defined chronic disease seems to be closely linked to the patient's socioeconomic situation. Keywords: Socioeconomic inequality; Disease process measures; Health status measures; Self-efficacy; Rheumatoid arthritis
