Purpose. The aim of this systematic review was to identify health or health belief factors associated with mammography attendance or with self-initiated medical help-seeking for breast cancer symptoms among women in Europe.Methods. Five databases were searched for articles published between 2005 and 2018. Meta-analyses were conducted for 13 factors related to screening attendance and two factors associated with help-seeking behaviour. Where there were too few studies to include in the meta-analysis, a narrative synthesis was undertaken.Results. Sixty-five studies were included. Never having had cervical screening (d = À.72, p < .001) and higher perceived barriers to mammography (d = À.40, p < .001) were associated with lower levels of screening attendance. Possessing health insurance (d = .49, p < .001), greater perceived benefits (d = .31, p < .001) and motivation (d = .36, p = .003) towards screening, and higher perceived seriousness (d = .24, p = .019) and susceptibility (d = .20, p = .024) towards breast cancer were associated with a higher level of screening attendance. Presenting with a non-lump symptom was associated with a longer time to presentation (d = .32, p < .001). The narrative synthesis revealed that previous benign breast disease was associated with a higher level of screening attendance but with a longer time to presentation.Conclusions. The review identified key similarities in factors associated with screening and help-seeking behaviours which offer scope for combined interventions aimed at women that target both behaviours. Furthermore, the review highlighted that fewer studies have focused on help-seeking behaviour, despite two thirds of breast cancer cases being self-detected. Future research should further examine predictors of help-seeking behaviour including a focus on modifiable factors, such as BMI, and physical activity.
What is already known on this subject?Attending regular breast screening appointments and seeking help promptly on self-discovery of a breast symptom are important as early detection has been shown to be associated with better prognosis. Demographic, socio-economic, and health factors are predictors of screening and help-seeking behaviours.Both screening and help-seeking behaviours are potential health care-avoiding actions, and women who delay seeking help for a breast symptom are also less likely to attend screening.
What does this study add?This study provides evidence of shared health beliefs and health factors that predict both screening attendance and help-seeking, which could be targeted in future combined health interventions to promote early detection. Health factors associated with screening attendance in Europe may differ from other locations, such as the United States and Australia. This study provides a call to action for more European research examining help-seeking behaviour using quantitative methodology and larger samples.
