The Voice of Experience: Diet and Weight Change in Women with Breast Cancer Associate with Psychosocial and Treatment-Related Challenges

Abstract
Purpose: This study investigated relationships between psychosocial and treatment-related factors, diet, and weight change in women treated with chemotherapy for early-stage breast cancer.
Methods: Comprehensive qualitative interviews were conducted with 28 women who were within 12 months of completing chemotherapy treatment.
Results: Changes in food intake and eating patterns were universal over the course of chemotherapy, with broad variability in treatment effects and associated dietary responses linked to weight change. Increased appetite, food cravings, and intake of energy-dense comfort foods were more common among women who gained weight during treatment (n = 11). Changes in taste, nausea, and emotional distress were central in promoting these dietary responses. Women who lost weight during treatment (n = 6) tended to report more severe and persistent side effects of treatment leading to poor appetite and lower food intake, and they were more likely to live alone.
Conclusions: While the etiology of weight change in this population is complex, this study suggests that changes in food intake related to treatment and psychosocial challenges may play an important role for some women. These findings may help to identify women who are most at risk of weight change during treatment and may inform the development of tailored dietary interventions.
Résumé
Objectif : Cette étude portait sur la relation entre les facteurs psychosociaux et ceux liés au traitement, l’alimentation et le changement de poids chez les femmes recevant de la chimiothérapie pour un cancer du sein de stade précoce.
Méthodes : Des entrevues qualitatives exhaustives ont été menées auprès de 28 femmes qui étaient à moins de 12 mois de terminer leur chimiothérapie.
Résultats : Les changements en matière d’apport alimentaire et d’habitudes alimentaires étaient universels durant la chimiothérapie, et la grande variabilité des effets du traitement et de la réponse alimentaire associée était liée à un changement de poids. L’appétit accru, les fringales et la consommation d’aliments réconfortants riches en énergie étaient plus courants chez les femmes qui ont pris du poids durant le traitement (n = 11). Les changements de goût, les nausées et la détresse émotionnelle étaient des éléments centraux de ces réponses alimentaires. Les femmes qui ont perdu du poids durant leur traitement (n = 6) ont généralement signalé des effets secondaires plus graves et persistants du traitement, entraînant un faible appétit et un apport alimentaire moindre. Elles étaient aussi plus susceptibles de vivre seules.
Conclusions : Même si l’étiologie du changement de poids chez cette population est complexe, cette étude suggère que les changements à l’apport alimentaire liés au traitement et aux défis psychosociaux peuvent jouer un rôle important chez certaines femmes. Ces résultats pourraient aider à identifier les femmes qui sont plus susceptibles de connaître un changement de poids durant leur traitement et pourraient guider l’élaboration d’interventions nutritionnelles adaptées.
