A Model-Based Meta-Analysis of Willingness to Participate in Cancer Screening

Educational inequalities in cervical cancer screening participation in 24 European countries

OBJECTIVES

Cervical cancer screening (CCS) is an important public health measure for early detection of cervical cancer and prevents a large proportion of cervical cancer deaths. However, participation in CCS is relatively low and varies substantially by country and socio-economic position. This study aimed to provide up-to-date participation rates and estimates on educational inequalities in CCS participation in 24 European countries with population-based CCS programmes.

STUDY DESIGN

This was a cross-sectional study.

METHODS

Using data from the European Health Interview Survey (EHIS) conducted in 2019, 80,479 women aged 25-64 years were included in the analyses. First, standardized participation rates and standardized participation rates by educational attainment were calculated for all 24 countries based on each country-specific screening programme organization. Second, a series of generalized logistic models was applied to assess the effect of education on CCS participation.

RESULTS

Screening participation rates ranged from 34.1% among low-educated women in Romania to 97.1% among high-educated women in Finland. We observed that lower-educated women were less likely to attend CCS than their higher-educated counterparts. Largest educational gaps were found in Sweden (odds ratio [OR] = 6.36, 95% confidence interval [CI] = 3.89-10.35) and Poland (odds ratio = 5.80, 95% CI = 4.34-7.75).

CONCLUSION

Population-based screening initiatives have successfully reduced participation differences between women with medium and high educational attainment in some countries; however, persistent disparities still exist between women with low and high levels of education. There is an urgent need to increase participation rates of CCS, especially among lower-educated women.

Predictors of cancer screening behavior of the working population in China based on the information-motivation-behavioral skills model

Background

The cancer screening rate in the working population is very low in China. Information-motivation-behavioral skills (IMB) model has been applied to elucidate screening behavior for various chronic diseases but has not been investigated in analyzing cancer screening behavior. This study aimed to examine factors influencing cancer screening behavior and their linkages based on the IMB model.

Methods

A cross-sectional study was conducted in Shanghai, China from August to October 2021. Data were obtained through an anonymous questionnaire. Predictive relationships between variables in the IMB model and cancer screening behavior were evaluated. Structural equation modeling (SEM) was constructed to demonstrate the utility of the IMB model.

Results

Among the 556 participants included in the analysis, 34.4% of participants had ever done a cancer screening. The construct validation analysis supported that the measure items included were acceptable. SEM found that knowledge of cancer warning signs and symptoms (β = 0.563, p < 0.001) and cancer screening behavioral skills (β = 0.264, p = 0.003) were related to participation in cancer screening, whereas cancer screening motivation was not directly influenced the participation in cancer screening (β = - 0.075, p = 0.372).

Conclusion

The cancer screening rate was found to be lower than expected in the working population. The IMB model could be used to make decisions in implementing behavioral interventions to participate in cancer screening among the Chinese working population. Enhancing the knowledge of cancer warning signs and symptoms and strengthening behavioral skills should be focused on to improve participation in cancer screening.

Effects of electronic personal health information technology on American women's cancer screening behaviors mediated through cancer worry: Differences and similarities between 2017 and 2020

Backgrounds

Thanks to their accessibility and low cost, electronic personal health information (ePHI) technologies have been widely used to facilitate patient-physician communication and promote health prevention behaviors (e.g. cancer screening). Despite that empirical evidence has supported the association between ePHI technology use and cancer screening behaviors, the underlying mechanism through which ePHI technology use influences cancer screening behaviors remains a topic of discussion.

Objective

This study investigates the relationship between ePHI technology uses and cancer screening behaviors of American women and examines the mediating role of cancer worry.

Methods

Data for this study were from the Health Information National Trends Survey (HINTS) collected in 2017 (HINTS 5 Cycle 1) and 2020 (HINTS 5 Cycle 4). The final sample included 1914 female respondents in HINTS 5 Cycle 1 and 2204 in HINTS 5 Cycle 4. Mann-Whitney U test, two-sample t-test, and mediation analysis were performed. We also referred to the regression coefficients generated by min-max normalization as percentage coefficients (bp) for the comparison.

Results

This study reports increased usage of ePHI technologies (from 1.41 in 2017 to 2.19 to 2020), increased cancer worry (from 2.60 in 2017 to 2.84 in 2020), and a stable level of cancer screening behaviors (from 1.44 in 2017 to 1.34 in 2020) among American women. Cancer worry was found to mediate the ePHI effect on cancer screening behaviors (bp = 0.005, 95% confidence interval [0.001, 0.010]) in a positive complementary mediation in 2020.

Conclusions

The research findings support a positive association between ePHI technology use and cancer screening behaviors, and cancer worry has been identified as a salient mediator. An understanding of the mechanism that prompts US women's cancer screening practices provides practical implications for health campaign practitioners.

Barriers and Facilitators to Participation in Health Screening: an Umbrella Review Across Conditions

Screening is an essential prevention practice for a number of health conditions. However, screening coverage remains generally low. Studies that investigate determinants of screening participation are becoming more common, but oftentimes investigate screening for health conditions in an individualized rather than integrated fashion. In routine clinical practice, however, healthcare professionals are often confronted with situations in which several screening procedures are recommended for the same patient. The consideration of their common determinants may support a more integrated screening approach. The objectives of this umbrella review were therefore to examine: 1) the determinants (barriers and facilitators) that have been identified in relation to recommended health screening procedures; and 2) the modifiable determinants (in primary care) common across health conditions or specific to individual procedures. Results were presented through a narrative synthesis. PubMed, PsycInfo and Cochrane were searched up to January 2022. Systematic reviews reporting determinants of participation in health screening procedures with grade A or B recommendation according to the US Preventive Services Task Force were included. A total of 85 systematic reviews were included, most which contained both qualitative and quantitative studies on determinants that describe individual factors (961 occurrences), social factors (113 occurrences, healthcare professional factors (149 occurrences), health system factors (105 occurrences) and screening procedure factors (99 occurrences). The most studied screening procedures concerned cervical cancer/human papillomavirus (n = 33), breast cancer (n = 28), colorectal cancer (n = 25) and the human immunodeficiency virus (n = 12). Other conditions have been under-studied (e.g. cardiovascular problems, lung cancer, syphilis). The individual domain, including determinants such as knowledge, beliefs and emotions, was the most covered across health conditions. Healthcare professional's recommendations and the quality of patient-provider communication were identified to have a strong influence on screening participation in most conditions. The other three domains included determinants which were more specific to a condition or a population. Various determinants modifiable in primary care were found in the individual domain and in the health system, healthcare professional and screening procedure domains. Quality was assessed as low for most systematic reviews included. The identification of various modifiable determinants common across conditions highlights the potential of an integrated screening participation approach. Interventions may address common determinants in a broader person-centred framework within which tailoring to specific procedures or populations can be considered. This approach needs to be explored in intervention studies. The systematic review registration is PROSPERO CRD42019126709.

A cross-sectional study on assessment of perceived threat to cervical cancer using health belief model among women in a slum area of Kolkata

BACKGROUND

Despite the implementation of various cervical cancer preventive strategies by the Government of India, there is a scarcity of knowledge and consequent low utilization of cervical cancer screening services among women in India. This contributes to the burden of cervical cancer among Indian women. This study was conducted to assess perceived threat-regarding cervical cancer among women and to identify its explanatory factors in a slum area of Kolkata.

MATERIALS AND METHODS

A cross-sectional study was conducted among 192 adult women from May to September 2019 in Kolkata. The multistage sampling technique was used using a structured schedule. Perceived threat to cervical cancer was measured using a composite score including perceived susceptibility and perceived severity constructs of the health belief model. Data were analyzed by descriptive statistics and multivariable logistic regression model using SPSS software version 16.

RESULTS

Overall, 22.9% of the participants had satisfactory levels of perceived threat to cervical cancer. Statistically significant association was found between unsatisfactory levels of perceived threat with reproductive age group (adjusted odds ratio [AOR] = 3.01; P = 0.036), education level up to primary (AOR = 2.89; P = 0.026), and unsatisfactory knowledge (AOR = 2.94; P < 0.001) among respondents. The multivariable regression model was of good fit.

CONCLUSION

The study population had very unsatisfactory levels of perceived threat to cervical cancer. Thus, to increase cervical cancer screening uptake among women, it is necessary to tailor robust behavior change communication campaigns to increase the perception of susceptibility and severity, thereby increasing the perception of threat of cervical cancer among women.

Systematic Construction and Validation of an Immune-Related Gene-Based Model to Predict Prognosis for Ovarian Cancer

Ovarian cancer (OC) is a malignancy with poor prognosis, stubborn resistance, and frequent recurrence. Recently, it has been widely recognized that immune-related genes (IRGs) have demonstrated their indispensable importance in the occurrence and progression of OC. Given this, this study aimed to identify IRGs with predictive value and build a prognostic model for a more accurate assessment. First, we obtained transcriptome and clinical information of ovarian samples from both TCGA and GTEx databases. After integration, we figured out 10 genes as immune-related prognostic genes (IRPGs) by performing the univariate Cox regression analysis. Subsequently, we established a TF-associated network to investigate its internal mechanism. The prognosis model consisting of 5 IRPGs was constructed later by lasso regression analysis. The comparison of the score with the clinical factors validated its independence and superiority in OC's prognosis. Moreover, the association between the signature and immune cell infiltration demonstrated its ability to image the immune situation of the tumor microenvironment. Finally, the reliability of the risk model was confirmed by the GEO cohort. Together, our study has constructed an independent prognostic model for OC, which may deepen the understanding of the immune microenvironment and help present novel biomarkers or ideas for targeted therapy.

Willingness to Receive Periodic Health Examination Based on the Health Belief Model Among the Elderly in Rural China: A Cross-Sectional Study

PURPOSE

This study aimed to explore factors affecting behavioral intention of receiving periodic health examinations (hereafter, BIE) among people aged 60 and over in rural China, namely, Shandong Province, using the extended health belief model (EHBM).

PATIENTS AND METHODS

Participants were selected using stratified multi-stage random sampling. Three cities were selected based on economic level. Subsequently, three counties and three villages were selected from each sample city and county. Finally, 30 respondents were selected from each sample village. Face-to-face surveys were conducted using a structured questionnaire between March and September 2017. Multiple linear regression was conducted to investigate the association between BIE and eight dimensions of EHBM: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, cues to action, health knowledge, and social support.

RESULTS

Of the 509 rural respondents aged 60 years and older, the average score of behavioral intention was 4.43±0.80. Multivariate linear regression analysis demonstrated poor BIE among participants who were men, were current smoker, were current drinker, were aged 70 years or over, had lower social support, and perceived lower self-efficacy, less benefits, and more barriers. Among them, barriers were found to have the strongest association with BIE (B'=-0.556; p<0.001). Qualitative interviews revealed that reasons for not receiving periodic health examinations (PHE) included pain, cost, difficulty in finding a health care provider, time and scheduling, potential lack of trust in the physician, and value of the PHE.

CONCLUSION

This study highlighted the importance of psychological variables in the acceptance of PHE among the elderly in rural China and provided insights for further intervention designs targeting identified groups and performed by general practitioners. Addressing medical mistrust, strengthening, and enhancing one's social support network and health communication channels, such as bulletin boards, may serve to facilitate BIE.
