A debate over the association between dietary patterns and obesity is not settled in the literature. Some studies suggest that there are significant differences in the mean body mass index (BMI) across dietary patterns, while others refute the result. Therefore, we extended this line of study to examine whether the influence of dietary pattern is strong enough to affect the incidence of obesity based on the criterion, BMI=25. We identified 3 dietary patterns using a cluster analysis of food intake data obtained from the food frequency survey conducted as a part of Korean genome epidemiologic study: 'variety', 'unrefined grain', and 'rice' dietary patterns. A Cox Hazard regression result showed that the all the dietary pattern variable parameters were not significant. Hence, it was concluded that the dietary patterns do not affect the incidence of obesity under the control of variables, such as age, energy intake, and etc.
