ABSTRACT
Breast and cervical are top cancers for women globally, but few studies have summarised how gender norms influence screening uptake, given sexual connotations and physical exposure. These beliefs may play a central role in decision-making, and understanding them is crucial to improving screening rates and services. This review scopes international literature for gender-based qualitative factors influencing women's screening uptake. A systematic search of peer-reviewed English articles in PubMed, Scopus, and CINAHL was conducted from inception until December 2019. Articles were included if they were about breast or cervical cancer screening, had mixed or qualitative methodology, and sampled women from the general population. 72 studies spanning 34 countries were analysed. Eight studies also included healthcare providers' views. Our narrative thematic analysis summarised primary themes extracted from each study into first-level subthemes, then synthesising second-level and third-level themes: (I) gender socialisation of women, (II) gender inequality in society, and (III) lack of empowerment to women in making screening decisions. Women tended to face sociocultural/role-based constraints, were expected to prioritise family, and keep bodily exposure to their husbands. Women showed low awareness and had fewer opportunities for health education compared to men. Male relations were often gatekeepers to financial resources needed to pay for screening tests. Screening risked community norms about women's or husbands' perceived embarrassing sexual behaviours. These findings suggest that interventions targeting unhelpful stigmatising beliefs about women's cancer screening must concurrently address community general norms, familial role-based beliefs, as well as at male relations who hold the purse-strings.
ABSTRACT
Colorectal cancer screening saves lives and is cost-effective. It allows early detection of the pathology, and enables earlier medical intervention. Despite clinical practice guidelines promoting screening for average risk individuals, uptake remains suboptimal in many populations. Few studies have examined how sociobehavioural factors influence screening uptake in the context of behaviour change theories such as the health belief model. This systematic review therefore examines how the health belief model's constructs are associated with colorectal cancer screening. Four databases were systematically searched from inception to September 2019. Quantitative observational studies that used the health belief model to examine colorectal screening history, intention or behaviour were included. A total of 30 studies met the criteria for review; all were of cross-sectional design. Perceived susceptibility, benefits and cues to action were directly associated with screening history or intention. Perceived barriers inversely associated with screening history or intention. The studies included also found other modifying factors including sociodemographic and cultural norms. Self-report of screening history, intention or behaviour, convenience sampling and lack of temporality among factors were common limitations across studies. The health belief model's associations with colorectal cancer screening uptake was consistent with preventive health behaviours in general. Future studies should examine how theory-based behavioural interventions can be tailored to account for the influence of socioecological factors.
