- Abstract
Purpose: Self-rated health has shown to be a strong predictor of mortality and some major chronic diseases. The purpose of this study was to investigate whether poor self-rated health also was related to an increased risk of subsequent development of cancer. Methods: Information on self-rated health, life-style factors, and other health-related risk factors was ascertained in a cohort of 25,532 persons participating in the Hordaland Health Study in 1997-1999. Information on development of cancer during 10 years of follow-up was obtained from the Norwegian Cancer Registry. The relationship between self-rated health and development of cancer was examined using Cox regression analysis adjusting for smoking and other life-style factors. Results: Respondents reporting a poor health showed a non-significant increased risk of overall cancer. Sub-analysis of the four most common types of cancer showed a statistically significant association between self-rated health and lung cancer. The adjusted hazard ratio was 3.88 (95 % CI; 0.99, 15.8) for those rating their health as poor compared to very good ( p for trend = 0.038). For the other types of cancer, we found a non-significant elevated risk associated with poor self-rated health. Conclusion: Respondents who perceive their health as poor had an increased risk of developing lung cancer also after adjusting for smoking. This suggests that self-rated health reflects a broad range of factors important for development of this cancer type. Nevertheless, due to the explorative analysis of the specific cancer types, these findings need to be repeated before elaborate interpretations can be made.
