Objectives :

Methods : The analysis included 11,554 participants with a baseline BMI < 25 kg/m²  from the SUN (Seguimiento Universidad de Navarra/University of Navarra Follow-up) prospective, open-recruitment cohort. Food consumption was assessed using a 136-item validated food-frequency questionnaire. A provegetarian food pattern (FP) was built by assigning positive scores to plant foods and reverse scores to animal foods as proposed by Martínez-González et al (2014). We also created a healthful provegetarian FP where healthy plant foods (fruits, vegetables, whole grains, nuts, legumes and olive oil) were positively weighted but less-healthy plant foods (juices, potatoes, refined grains, pastries and other vegetable oils) and animal foods were negatively weighted. To build an unhealthful provegetarian FP, less-healthy plant foods were positively weighted and animal and healthy plant foods were negatively weighted as suggested by Satija et al (2017). Participants were categorized into energy-adjusted quintiles of the different versions of a provegetarian FP. We calculated adjusted hazard ratios (HR) of overweight/obesity (BMI ≥ 25 kg/m²) and their 95% confidence intervals (CI).

Results :

Conclusions :

Among relatively young graduates, better conformity with a healthy provegetarian diet was associated with a reduced risk of overweight/obesity, whereas no consistent trend was found for a FP that emphasized less-healthy plant foods.
