Dietary consumption trajectory profiles over time of French adults from the NutriNet-Sante cohort (2014-2022): multicriteria analysis of sustainability.

ABSTRACT:

Background

Dietary patterns significantly impact climate change and morbidity, making transitions to sustainable diets urgent. Few studies explore repeated dietary measures collected over several years or variations across distinct consumer profiles characterized by sociodemographic and dietary patterns.

Objective

Our study aims to identify dietary trajectory profiles in French adults (2014-2022), assessing environmental, nutritional, and health outcomes.

Methods

Consumption data from 17,187 NutriNet-Santé cohort participants (52% women, average age 48y, SD = 16) were collected via food frequency questionnaires in 2014 (weighted to the French Census), 2018, and 2022. Dietary trajectory profiles were modeled using Group-based multi-trajectory modeling based on principa
