Gender-varying associations between physical activity intensity and mental quality of life in older cancer survivors.

ABSTRACT: PURPOSE:Physical activity can enhance quality of life in cancer survivors, but this conclusion is based largely on research linking moderate-to-vigorous physical activity with quality of life. Light-intensity physical activity may be more feasible than more strenuous exercise for many older cancer survivors. This study reports a secondary analysis of baseline data from a lifestyle behavior intervention trial and examines the hypothesis that older cancer survivors who engage in more light-intensity physical activity, independent of moderate-to-vigorous activity, will report better mental quality of life. METHODS:Older (?65 years), overweight or obese breast, prostate, or colorectal cancer survivors (n = 641, 54% female) self-reported their physical activity and mental quality of life (i.e., mental health, emotional role functioning, vitality, and social role functioning from the Short-Form 36 Health Status Survey) as a part of the RENEW trial baseline assessment. Analysis of covariance was used to test hypotheses. RESULTS:For older women (but not men), light physical activity was positively associated with mental quality of life after adjusting for moderate-to-vigorous physical activity. Light physical activity that involved social participation appeared to be responsible for this association. For older men (but not women), moderate-to-vigorous physical activity was positively associated with mental quality of life. CONCLUSIONS:Some activity appears to be better than none for important dimensions of mental quality of life. Experimental research is needed to test the hypothesis that older cancer survivors should strive to avoid inactivity regardless of whether they are able to engage in moderate-to-vigorous physical activity.

Project description:PurposeHealth-related quality of life (HRQOL) in older persons is influenced by physical and mental health, as well as by their social contacts and social support. Older women and men have disparate types of social networks; they each value social ties differently and experience loneliness in unique and personal ways. The aim of this study is, therefore, to determine the longitudinal association between loneliness and social isolation with HRQOL in older people-separated by gender.MethodsData stem from the third and fourth follow-up of the ESTHER study-a population-based cohort study of the older population in Germany. A sample of 2171 older women and men (mean age: 69.3 years, range 57-84 years) were included in this study; HRQOL was assessed by using the Short Form-12 questionnaire (SF-12). Data on physical and mental health, loneliness, and social networks were examined in the course of comprehensive home visits by trained study doctors. Gender-specific linear regression analyses were performed to predict physical quality of life (measured by the PCS, physical component score of the SF-12) and mental quality of life (measured by the MCS, mental component score) after three years, adjusted by socioeconomic variables as well as physical, mental, and social well-being.ResultsAt baseline, PCS was 41.3 (SD: 10.0) in women and 42.2 (SD: 9.6) in men (p = .04). MCS was 47.0 (SD: 10.2) in women and 49.6 (SD: 8.6) in men (p < .001). In both genders, PCS and MCS were lower three years later. Loneliness at t0 was negatively associated with both PCS and MCS after three years (t1) among women, and with MCS but not PCS after three years among men. In both genders, the strongest predictor of PCS after three years was PCS at t0 (p < .001), while the strongest predictors of MCS after three years were MCS and PCS at t0.ConclusionHRQOL in elderly women and men is predicted by different biopsychosocial factors. Loneliness predicts decreased MCS after three years in both genders, but decreased PCS after three years only in women. Thus, a greater impact of loneliness on the health of older women can be surmised and should therefore be considered in the context of their medical care.

Project description:ObjectiveWe aimed to investigate the associations between diabetes and quality of life (QOL) among breast cancer survivors.MethodsA cross-sectional survey was conducted at 34 Cancer Recovery Clubs across China from May 2014 to January 2015. Quality of life was measured by the Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the Quality of Life Questionnaire-Breast Cancer Module 23 (QLQ-BR23, simplified Chinese version). Information on social-demography, diagnosis and treatment of tumors, and diabetes mellitus were collected by self-reported questionnaires. Univariate analyses of covariance (ANCOVA) was performed to assess the difference in QOL between patients with or without diabetes mellitus, and multiple linear regression models were used to examine the associations after controlling for confounders.ResultsDiabetes, both of type 1 diabetes (T1DM) and type 2 diabetes (T2DM) significantly reduced QOL. This effect of diabetes on QOL is independent of tumor size, regional lymph node metastasis, distant metastasis and tumor stage index (TNM). After adjusting for different social-demography, diagnosis and treatment of the tumor, the tumor's stage and other chronic comorbidities, breast cancer survivors with diabetes got significantly lower scores in functional dimensions (including physical, role, emotional and social functionings measured by EORTC QLQ-C30; body image (BRBI) and future perspective (BRFU) measured by QLQ-BR23, as well as economic difficulties than those without diabetes (Padjusted<0.05). Diabetic patients also obtained higher scores in symptom dimensions, including fatigue, nausea and vomiting, pain, dyspnoea, insomnia, constipation and diarrhoea measured by EORTC QLQ-C30; side effects, breast symptoms and upset by hair loss measured by QLQ-BR23 (Padjusted<0.05). Compared to patients with T1DM, those with T2DM are likely to suffer more by loss of functioning.ConclusionsDiabetes was associated with the decreased QOL for breast cancer survivors.
