title: Association between Motives for Dish Choices during Home Meal Preparation and Weight Status in the NutriNet-Santé Study.
abstract: Although home cooking has been associated with a lower body mass index in a few studies, no data exists on the motives behind food dish choices during home meal preparation and on their association with overweight. This study aimed to evaluate this association in 50,003 participants from the NutriNet-Santé cohort. Dimensions underlying the importance of 27 criteria possibly influencing dish choices were determined using an exploratory factor analysis. The association between dish choice motives and overweight (including obesity) was estimated using logistic regression models adjusted for sociodemographic and lifestyle characteristics. Five dimensions of dishes choice motives emerged: healthy diet (e.g., "nutritional balance of the dish"), constraints (e.g., "my cooking skills"), pleasure (e.g., "originality of the dish"), specific diets (e.g., "my health status"), and organization (e.g., "what I planned to eat"). A negative association was observed between the healthy diet factor and being overweight (OR = 0.65 (95% CI (confidence interval): 0.62-0.67)), whereas a positive association appeared for factors regarding pleasure (OR = 1.14 (95% CI: 1.10-1.19)) and specific diets (OR = 1.19 (95% CI: 1.17-1.22)). No significant associations were observed for constraints and organization. The significant associations between dish choice motives and overweight suggested the interest of focusing on these motives in order to promote healthier food choices during home cooking.
