The impact of depression on adherence to organized and opportunistic breast cancer screening

Breast cancer screening participation in women using mental health services in NSW, Australia: a population study

PURPOSE

Population screening programs have contributed to reduced breast cancer mortality, but disadvantaged or vulnerable groups may not have shared these improvements. In North American and European studies, women living with mental health conditions have reduced breast screening rates. There are no current Australasian data to support health system planning and improvement strategies.

METHODS

The New South Wales (NSW) BreastScreen program offers free screening to NSW women aged 50-74. We compared 2-year breast screening rates for mental health service users (n = 33,951) and other NSW women (n = 1,051,495) in this target age range, after standardisation for age, socioeconomic status and region of residence. Mental health service contacts were identified through linkage to hospital and community mental health data.

RESULTS

Only 30.3% of mental health service users participated in breast screening, compared with 52.7% of other NSW women (crude incidence rate ratio 0.57, 95% CI 0.56-0.59). Standardisation for age, socioeconomic disadvantage or rural residence did not alter this screening gap. Around 7000 fewer women received screening than would be expected from comparable population rates. Screening gaps were largest in women over 60 and in socioeconomically advantaged areas. Women with severe or persistent mental illness had slightly higher screening rates than other mental health service users.

CONCLUSIONS

Low breast cancer screening participation rates for NSW mental health service users suggest significant risk of later detection, possibly leading to more extensive treatment and premature mortality. Focussed strategies are needed to support greater breast screening participation for NSW women who use mental health services.

Association of depression with adherence to breast cancer screening among women aged 50 to 74 years in the United States

RATIONALE, AIMS, AND OBJECTIVES

Previous research has shown inconsistent results regarding the association of depression and screening mammography use behaviours. This study aimed to assess the relationship between women's depression and mammography adherence.

METHODS

This cross-sectional study used data from the 2016 Behavioural Risk Factor Surveillance System and employed the Health Belief Model (HBM). The primary independent variable was the presence of depression. The dependent variable was adherence to biennial screening mammography based on the US Preventive Services Task Force guidelines. Demographic characteristics and HBM constructs were included as covariates. Univariate and multivariate logistic regressions were used.

RESULTS

A total of 139 550 women were included (weighted n = 48 712 531). Among them, 23.1% reported the presence of depression (n = 32 247). The unadjusted odds ratio (OR) for mammography use in women with depression was 0.85 (95% confidence interval [CI], 0.80-0.91, P < .001) compared with women without depression, and the probability of mammography use was significantly lower in women with depression (76.3%; 95% CI, 75.4-77.3) compared with women without depression (79.1%; 95% CI, 78.5-79.6). However, the adjusted OR was not statistically significant when controlling for demographic and HBM characteristics (1.02; 95% CI, 0.93-1.11, P = .698), and the probabilities of mammography use were similar between women with depression (80.1%; 95% CI, 79.0-81.3) and without depression (79.9%; 95% CI, 79.2-80.6).

CONCLUSIONS

Depression itself was related to nonadherence with mammography screening guidelines. However, after controlling for demographic and HBM characteristics, depression was not associated with adherence with mammography screening guidelines.

Type C Personality and Depression Among Newly Diagnosed Breast Cancer Patients: The Mediating Role of Sense of Coherence

PURPOSE

This study aims to explore the mediating role of sense of coherence in the relationship of type C personality and depression among newly diagnosed breast cancer patients.

METHODS

A descriptive and correlational survey was conducted in 600 breast cancer patients aged ≥18 years from September 2018 to March 2019 in Zhengzhou, China. The demographic questionnaire, Cancer Behavior Scale, Sense of Coherence Scale and Hamilton Depression Scale were included in this study. Data analysis was performed by correlation analysis, multiple linear regression analysis, and structural equation modeling.

RESULTS

The valid questionnaires were 575 (effective response rate: 95.8%). The score of sense of coherence was negatively correlated with type C personality and depression (r = -0.41, P < 0.01; r = -0.58, P < 0.01); the score of type C personality and depression were positively correlated (r = 0.51, P < 0.01). The results of multiple linear regression analysis revealed that the effect of type C personality on depression was partly mediated by sense of coherence, which was confirmed by structural equation modeling. The mediation effect accounts for 45.2% (0.269/0.594) of the total effect.

CONCLUSION

The results of this study revealed that sense of coherence as a partial mediating role is essential for reducing the influence of type C personality on depression. Early and targeted psychological interventions on sense of coherence are needed to alleviate the symptom of depression in newly diagnosed breast cancer patients.
