Factors influencing breast cancer screening practices among women worldwide: a systematic review of observational and qualitative studies.

BACKGROUND: The variation in breast cancer incidence rates across different regions may reflect disparities in breast cancer screening (BCS) practices. Understanding the factors associated with these screening behaviors is crucial for identifying modifiable elements amenable to intervention. This systematic review aims to identify common factors influencing BCS behaviors among women globally. METHODS: Relevant papers were sourced from PubMed, Scopus, Embase, and Google Scholar. The included studies were published in English in peer-reviewed journals from January 2000 to March 2023 and investigated factors associated with BCS behaviors. RESULTS: From an initial pool of 625 articles, 34 studies (comprising 29 observational and 5 qualitative studies) with 36,043 participants were included. Factors influencing BCS behaviors were categorized into nine groups: socio-demographic factors, health status history, knowledge, perceptions, cultural factors, cues to action, motivation, self-efficacy, and social support. The quality appraisal scores of the studies ranged from average to high. CONCLUSIONS: This systematic review highlights factors pivotal for policy-making at various levels of breast cancer prevention and assists health promotion professionals in designing more effective interventions to enhance BCS practices among women.

Factors associated with preventive behaviors of COVID-19 among adolescents: Applying the health belief model.

BACKGROUND: The emergence of a new pandemic caused by a novel coronavirus (COVID-19) is a unique challenge for public health (all age and sex groups). OBJECTIVE: This study aimed to explore the adolescents' perceptions of preventive behaviors to avoid COVID-19 disease based on the health belief model (HBM). METHOD: This cross-sectional study was conducted on 797adolescents (aged between 12 and 18 years old), who were 7th-12th -grade students of 24 randomly selected schools from 28th May to June 28, 2020 in Isfahan, Iran. An online self-administered questionnaire was adapted to measure the adolescents' perceived threats, barriers, benefits, self-efficacy, and cues to action toward protective behaviors. RESULTS: Findings indicated that the adolescents' mean age was 14.7 (SD = 1.7) and 53.7% of them were female. Regardless of gender difference, there was a significant positive correlation between the adolescents' protective behaviors and their self-efficacy (r = 0.62, P < 0.001), perceived benefit (r = 29, P < 0.001), and perceived severity (r = 0.15, P < 0.001), while there was a significant negative correlation between the adolescents' protective behaviors and their perceived susceptibility (r = -0.11, P < 0.001), as well as their perceived barrier (r = -0.21, P < 0.001). The result of the Hierarchical regression analysis also revealed that the HBM model had a significant predictive power for preventing measures towards coronavirus disease in adolescents (Adj R2 = 0.46, p < 0.001). The results also showed that self-efficacy was the strongest predictor (ß = 0.59, P < 0.001) in explaining protective behaviors in adolescents. CONCLUSION: In the context of coronavirus disease pandemic in adolescents, the health belief model could provide a useful framework for planners to develop educational programs. Moreover, in such a context, strategies to promote self-efficacy in adolescents should be considered more carefully to help them improve their protective behaviors.
