ABSTRACT
Resumen Un sobreviviente de cáncer padece continuamente manifestaciones autonómicas debidas a la enfermedad, su tratamiento oncológico, y el estrés psicológico con que se enfrenta continuamente. Una de las medidas psicofisiológicas utilizada para la valoración del estrés es la disminución de la temperatura periférica. En contraparte, los procedimientos psicológicos de relajación para el manejo de estrés buscan incrementar la temperatura. Sin embargo, se desconoce si esta respuesta es igual en todas pacientes. El objetivo de esta investigación fue examinar los cambios de temperatura durante un protocolo de estrés psicosocial y relajación en pacientes sobrevivientes de cáncer de mama. Adicionalmente, se evaluó el autorreporte de dolor y su interferencia con el funcionamiento psicosocial. Los resultados mostraron variaciones de temperatura periférica en las pacientes; sin embargo, no todas las pacientes presentaron el mismo patrón de temperatura, encontrando 3 subgrupos de pacientes, cuyas trayectorias lineales de temperatura permitieron generar un pronóstico afectivo para el manejo de estrés. Por autorreporte, no se encontraron diferencias psicosociales entre los subgrupos, aunque sí se encontró una asociación inversa entre la interferencia del sueño y la temperatura periférica. Se concluye que la temperatura periférica permite distinguir a las pacientes que se les dificulta el manejo del estrés psicosocial de aquellas que se benefician de los procedimientos psicológicos de relajación.
Abstract A cancer survivor continually suffers from autonomic manifestations due to the disease, their cancer treatment, and the psychological stress they continually face. One of the psychophysiological measures used to assess stress is the decrease in peripheral temperature. In contrast, psychological relaxation procedures for stress management seek to increase temperature. However, it is unknown if this response is the same in all patients. This research examined breast cancer survivors' temperature changes during psychosocial stress and relaxation protocol. Additionally, self-reported pain and its interference with psychosocial functioning were evaluated. The results showed peripheral temperature variations in the patients; however, not all patients presented with the same temperature pattern, finding three subgroups of patients whose linear temperature trajectories allowed generating an affective prognosis for stress management. By self-report, no psychosocial differences were found between the subgroups, although an inverse association between sleep interference and peripheral temperature was found. It is concluded that peripheral temperature distinguishes patients who find it challenging to manage psychosocial stress from those who benefit from psychological relaxation procedures.
ABSTRACT
Purpose: The present study aimed to clarify the status of exercise and related factors among survivors of breast cancer. Methods: Questionnaires were distributed to survivors of breast cancer. The question items addressed the status of exercise participation, knowledge about the effects of exercise and need for support. Factors associated with exercise participation were analyzed using logistic regression analysis. Results: Among 293 valid responses (rate, 84.2%). Fifty-eight point four percent participated in exercise and 41.3% decreased exercise participation after being diagnosed with breast cancer. Furthermore, 91.9% needed support from health care providers regarding exercise. About 70% of respondents were aware that exercise improves sleep, but <50% knew that exercise ameliorates symptoms associated with breast cancer. Among seven factors, age, employment status and chemotherapy were associated with exercise status. Conclusion: Breast cancer survivors who are younger, employed and undergoing chemotherapy might not participate in exercise. The preventive effects of exercise on breast cancer and the importance of continuing daily exercise should be promoted. Health care providers should provide support for patients to participate in exercise considering the influence of treatment and physical capabilities.
ABSTRACT
OBJECTIVES: We aimed to evaluate dietary intake among female breast cancer survivors in a cross-sectional study. METHODS: A total of 127 women who had breast cancer surgery at least 6 months before baseline were included. Dietary intake of female breast cancer survivors was assessed through self-reported 3 day-dietary records. To compare dietary intake between breast cancer survivors and general female population without cancer, we selected the 1:4 age matched women from the 2011 Korean National Health and Nutrition Examination Survey (KNHANES). In the KNHANES, participants were asked about their dietary intake using the 24-hour dietary recalls. We also examined whether dietary intake varied by age group, cancer stage, or time since surgery among breast cancer survivors. We used the generalized linear model to compare their dietary intakes. RESULTS: Intakes of total energy, beta-carotene, folate, vitamin C, plant iron and fruits were lower among breast cancer survivors with longer time since surgery compared to those with shorter time (p < 0.05). Breast cancer patients with higher stage at diagnosis tended to consume less legumes (p = 0.01) than those with lower stage. When we compared dietary intake between breast cancer survivors and the general female population without cancer, breast cancer survivors were more likely to consume most of macro- and micro-nutrients in larger quantity (p < 0.05) and adhere to healthier diet characterized by higher intakes of legumes, seed and nuts, vegetables and fishes and shells than the general female population who never had been diagnosed with cancer (p < 0.05). CONCLUSIONS: Our study results suggested that the intakes of nutrients and foods varied by time since surgery and cancer stage among breast cancer survivors and dietary intakes among breast cancer survivors differed from that in the general population. Further prospective studies are warranted to explore the association between dietary intakes of specific food items and survival among Korean breast cancer survivors.
