Résumé
Nutrition is often used by cancer survivors as a lever to take charge of their own health. However, some dietary behaviors are not currently recommended for patients without medical supervision. This study aimed at evaluating weight-loss restrictive diets and fasting practices among cancer survivors of the NutriNet-Santé cohort, as well as related sociodemographic and lifestyle factors. In October 2016, 2,741 cancer survivors had completed a specific questionnaire about their practices. Fasting and non-fasting patients (respectively dieting and non-dieting) were compared using logistic regression models. Analyses were weighted according to the age, sex, and cancer location distribution of French cancer cases. 13.8% had already practiced weight-loss restrictive diet since their diagnosis. They were more likely to be women, professionally active, overweight/obese, to use dietary supplements and to have breast cancer (all p<0.05). 6.0% had already fasted, 3.5% since their diagnosis. They were more likely to be younger, with higher educational level, higher incomes, professionally active, to have a healthy weight, and to use dietary supplements (all p<0.05). Fasting was associated with the opinion that such practice could improve cancer prognosis (p<0.0001). Patients who received nutritional information from health care professionals were less likely to practice fasting or weight-loss restrictive diet (0.42[0.27-0.66], p<0.0001 and 0.49[0.38-0.64], p<0.0001 respectively). This study provided original results suggesting that weight-loss restrictive diets are widely practiced by cancer survivors. Fasting was less common in this study though non negligible. Sources of nutritional information received since cancer diagnosis seemed to be a key determinant of these practices. This article is protected by copyright. All rights reserved.
