Treatment-induced menopause symptoms among women with breast cancer undergoing chemotherapy in China: a comparison to age- and menopause status-matched controls.

OBJECTIVE: Whether women with breast cancer experience more severe menopause symptoms than comparison women without a history of breast cancer diagnosis remains unclear. We aimed to investigate whether women with breast cancer undergoing chemotherapy experience more severe menopause symptoms than comparison women and explore various factors influencing menopause symptoms in women with breast cancer undergoing chemotherapy. METHODS: This cross-sectional observational study recruited 423 women with breast cancer undergoing chemotherapy and 1,829 community women without breast cancer. All participants completed a questionnaire assessing menopause symptoms using the Menopause Rating Scale and general characteristics (eg, sociodemographic and clinical data). Propensity score matching was used to reduce the confounders between the two groups. Student's t test or Mann-Whitney U test and chi-square tests were used to compare the differences in menopause symptoms between the two groups. Multivariate linear regression analysis was performed to explore various factors influencing menopause symptoms in women with breast cancer undergoing chemotherapy. RESULTS: After propensity score matching, 808 participants were included. The mean ages of women with breast cancer undergoing chemotherapy and comparison women were 49.58 and 49.10 years, respectively. Women with breast cancer undergoing chemotherapy experienced significantly more severe vasomotor symptoms than comparison women. However, comparison women had higher Menopause Rating Scale scores and more severe menopause symptoms than women with breast cancer undergoing chemotherapy. Age, occupational status, chemotherapy-induced amenorrhea, family history of cancer, chemotherapy stage, mindfulness, resiliency, and illness perception were associated with menopause symptoms in women with breast cancer undergoing chemotherapy. CONCLUSIONS: Vasomotor symptoms are prominent among women with breast cancer undergoing chemotherapy. Understanding the factors contributing to menopause symptoms is crucial for healthcare practitioners to develop supportive guidelines for the well-being of women with breast cancer undergoing chemotherapy.

The effect of mindfulness and psychological capital on mental health of breast cancer patients: Based on polynomial regression and response surface analysis.

OBJECTIVE: To explore the combined effects of mindfulness and psychological capital on mental health of breast cancer patients and to examine the mediating effect of positive emotions in their relationship. METHODS: A convenient sampling method was used in this study, and 522 breast cancer patients aged 18 to 59 who received chemotherapy in a tertiary cancer hospital were enrolled. Polynomial regression with response surface analysis was mainly employed to explore the relationship between mindfulness, psychological capital, and mental health. A block-variable approach was used to verify the mediating effect of positive emotions. RESULTS: In cases of congruence, mental health was better when mindfulness and psychological capital were both high instead of being both low (the slope of the congruence was 0.540, p < 0.001); In cases of incongruence, poorer mental health was found in breast cancer patients with low psychological capital and high mindfulness compared with those who had high psychological capital and low mindfulness (the slope of the incongruence was -0.338, p < 0.001), and the combined effects were a positive curve (positive U-shaped) related to mental health (ß = 0.102, p = 0.040). In addition, positive emotions played a mediating role in the relationship between the block variable (mindfulness and psychological capital) and mental health, and the indirect effect was 0.131. CONCLUSIONS: This study expanded the research on the effects of mindfulness and psychological capital in improving mental health as well as the conflict between the two variables related to mental health by employing a new analytical technique among breast cancer patients.

Dyadic association between mindfulness, family avoidance of communication about cancer and fear of cancer recurrence among breast cancer couples: A cross-sectional study.

PURPOSE: The research focused on examining the dyadic relationship between mindfulness, fear of cancer recurrence (FCR), and family avoidance of communication about cancer (FACC) within breast cancer couples. METHODS: This study utilized a cross-sectional approach to gather data from 249 breast cancer couples. Participants completed self-report measures assessing mindfulness, FCR, and FACC. The Actor-Partner Interdependence Mediation Model was applied to analyze how each individual's and their partner's mindfulness affected their own and their partner's FCR, as well as the mediating role of FACC in this relationship. RESULTS: The study found that the average FCR score for breast cancer patients was (32.59 ± 10.05), while their spouses had a score of (34.39 ± 8.60). The bootstrap method showed that self-FACC as a mediator between mindfulness in breast cancer couples and their own FCR (patient: ß = -0.044, P = 0.019; spouse: ß = -0.046, P = 0.007). Patients' FACC influenced the connection between their mindfulness and spouses' FCR (ß = -0.031, P = 0.030). CONCLUSIONS: The findings highlight the potential for interventions that focus on mindfulness and communication enhancement to alleviate FCR and improve the overall well-being of breast cancer couples.

A moderated mediation model of perceived stress, negative emotions and mindfulness on fertility quality of life in women with recurrent pregnancy loss.

PURPOSE: This study aimed to investigate the level of fertility related quality of life (FertiQoL) in women with recurrent pregnancy loss (RPL), and to further examine moderated mediation effects of dispositional mindfulness and negative emotions on the relationship between perceived stress and FertiQoL. METHODS: A cross-sectional study was conducted with 262 participants recruited from the infertility outpatient clinics. A self-administered, structured questionnaire including the Simplified Chinese version of FertiQoL tool, the Perceived Stress Scale-10 (PSS-10), the Chinese Version of the Hospital Anxiety and Depression Scale (HADS), and the Mindfulness Attention Awareness Scale (MAAS) was used to collect information in this research. The mediation model and moderated mediation model were conducted using the PROCESS macro for SPSS. RESULTS: The mean score of Core FertiQoL was 64.59 (SD = 14.76) among women with RPL. Mediation analysis revealed that the association between perceived stress and FertiQoL was partially mediated by negative emotions (indirect effect = - 0.194 for anxiety, and - 0.151 for depression, all P < 0.001). Moderated mediation analysis indicated that the indirect effects of perceived stress on FertiQoL through negative emotions were significantly moderated by dispositional mindfulness. Specifically, the indirect effects of perceived stress on FertiQoL through negative emotions decreased were significant as dispositional mindfulness levels increased. CONCLUSION: Overall, women with RPL experienced poor FertiQoL. The Moderated mediation model provides a better understanding of how perceived stress, negative emotions and dispositional mindfulness work together to affect FertiQoL. Interventions aiming to improve FertiQoL in women with RPL should consider targeting these aspects.
