Abstract
Background and aims
Epidemiological studies on the association between yogurt consumption and the risk
of overweight/obesity are scarce. We prospectively examined the association of yogurt
consumption with overweight/obesity and average annual weight gain.
Methods and results
Prospective cohort study of 8516 men and women (mean age 37.1, SD: 10.8 y). Participants
were followed-up every two years. Participants were classified in 5 categories of
yogurt consumption at baseline: 0–2, >2–<5, 5–<7, 7 and ≥7 servings/week. Outcomes
were: 1) average yearly weight change during follow-up; and 2) incidence of overweight/obesity.
Linear regression models and Cox models were used to adjust for potential confounders.
After a median follow-up of 6.6 years, 1860 incident cases of overweight/obesity were
identified. A high (>7 servings/week) consumption of total and whole-fat yogurt was
associated with lower incidence of overweight/obesity [multivariable adjusted hazard
ratios = 0.80 (95% CI: 0.68–0.94); and 0.62 (0.47–0.82) respectively] in comparison
with low consumption (0–2 servings/week). This inverse association was stronger among
participants with higher fruit consumption.
Conclusion
In this Mediterranean cohort, yogurt consumption was inversely associated with the
incidence of overweight/obesity, especially among participants with higher fruit consumption.
