Self-assessed health, perceived stress and non-participation in breast cancer screening: A Danish cohort study

Abstract

ObjectivePopulation-based cancer screening is offered in many countries to detect early stages of cancer and reduce mortality. Screening efficiency and equality is susceptible due to a group of non-participants. We investigated associations between self-assessed health, perceived stress and subsequent non-participation in breast cancer screening. MethodsThis population-based cohort study included 4512 women who had participated in a Health Survey in 2006 and who were also the target group (aged 50–69years) for the first organised breast cancer screening programme -3years later in the Central Denmark Region in 2008–2009. ResultsA U-shaped association was observed for physical health assessment as women with the highest (PR=1.28, 95% CI: 1.06–1.55), and the lowest (PR=1.41, 95% CI: 1.18–1.68) physical health scores were less likely to participate in the programme than women with physical health scores in the middle range. Women with low mental health assessment were more likely not to participate than women with mental health scores in the middle range (PR=1.44, 95% CI: 1.22–1.69). Higher non-participation propensity was also observed for women with the highest perceived stress scores (PR=1.27, 95% CI: 1.07–1.51) compared with women scoring in the middle range. ConclusionsWomen with highest and lowest self-assessed physical health, with lowest mental health or highest perceived stress were significantly more likely not to participate in breast cancer screening 2-3years later than women who reported average health. Interventions targeting these groups may promote equal participation in future breast cancer screening programmes.
