Divorce after breast cancer diagnosis and its impact on quality of life.

OBJECTIVE

This study aims to identify factors associated with divorce following breast cancer diagnosis and measures the impact of divorce on the quality of life (QoL) of patients.

METHODS

We used cross-sectional survey data collected at breast cancer outpatient clinics in South Korea from November 2018 to April 2019. Adult breast cancer survivors who completed active treatment without any cancer recurrence at the time of the survey ( = 4,366) were included. The participants were classified into two groups: "maintaining marriage" and "being divorced," between at the survey and at the cancer diagnosis. We performed logistic regression and linear regression to identify the factors associated with divorce after cancer diagnosis and to compare the QoL of divorced and nondivorced survivors.

RESULTS

Approximately 11.1/1,000 of married breast cancer survivors experienced divorce after cancer diagnosis. Younger age, lower education, and being employed at diagnosis were associated with divorce. Being divorced survivors had significantly lower QoL (Coefficient [Coef] = -7.50; 95% CI = -13.63, -1.36), social functioning (Coef = -9.47; 95% CI = -16.36, -2.57), and body image (Coef = -8.34; 95% CI = -6.29, -0.39) than survivors who remained married. They also experienced more symptoms including pain, insomnia, financial difficulties, and distress due to hair loss.

CONCLUSION

Identifying risk factors of divorce will ultimately help ascertain the resources necessary for early intervention.
