Abstract
Poor self-rated health (SRH) is associated with various adverse health outcomes, including cardiovascular disease. Little is known about SRH and health-related quality of life (HRQoL) as predictors of first-time venous thromboembolism (VTE). Our aim was to investigate the association between SRH, HRQoL, and risk of VTE in a whole cohort, as well as in women and men separately. A total of 108,025 middle-aged inhabitants (51 % women) of Västerbotten, Sweden, participated in a health examination between 1985 and 2014. Data on SRH, HRQoL, and potential confounders were collected by questionnaire. Participants were followed as a cohort and validated first-time VTE events were registered. The mean follow-up time was 13.9 years, during which 2054 participants experienced a first-time VTE. Overall, 27 % of participants reported their health as very good, 46 % as good, 20 % as average, 5 % as somewhat bad, and 1 % as bad. In a multivariable analysis, compared with participants who self-rated as having very good SRH, hazard ratios (95 % confidence intervals) for VTE were 1.17 (1.02-1.33) with good SRH, 1.27 (1.09-1.47) with average SRH, and 1.48 (1.00-2.18) with bad SRH. The risk of VTE increased with lower SRH for both men (p for trend 0.02) and women (p for trend 0.04). In a fully adjusted model, we also found significant associations between four aspects of HRQoL (general health, bodily pain, vitality, emotional well-being) and VTE risk. In conclusion, lower perceived health is associated with an increased risk of VTE in both men and women.
