The association between yogurt consumption (YC) and the risk of overweight/obesity (over/obes) remains elusive. Therefore our objective was to examine longitudinally this association. Methods: Prospective cohort study (SUN Project) of 8,516 participants initially free of over/ob, with a mean age of 37.1‐y (SD: 10.8). Participants were followed up through mailed questionnaires every two years. YC at baseline was classified in 3 categories: low (0‐2 serv/wk), moderate (>2‐<7/wk) or high (蠅7/wk). Cox models were used to obtain adjusted hazard ratios (HR) for over/obes during follow‐up (median 6.6 y). Results: During follow‐up, 1860 incident cases of over/ob were identified. High YC was associated with a lower risk of becoming over/ob [adjusted HR=0.88 (95% CI: 0.78‐0.99)]. This inverse association was stronger in the subgroup of participants with better adherence to the Mediterranean diet (MeDiet) [HR=0.75 (0.61‐0.91)]. We also observed stronger associations among participants with fruit consumption above the median (269 g/d), [HR=0.79 (0.66‐0.94)] (p for interaction= 0.055 and p=0.0006 for whole‐fat and low‐fat yogurt, respectively). Conclusions: In this Mediterranean cohort high yogurt consumption at baseline was associated with lower risk of over/obes during follow‐up. This inverse association was stronger if MeDiet adherence or fruit consumption were higher. Grant Funding Source : Supported by Danone Nutricia Research, Centre Daniel Carasso
