Dietary habits of middle-aged and elderly individuals affected by periodontal disease (PD) differ from those who are unaffected by it, according to previous reports. However, in young adults, there are only a few reports that show a correlation between nutrient/food intake and PD. Moreover, no report till date has assessed the correlation between dietary habits and PD using a self-administered diet history questionnaire (DHQ). Therefore, we assessed this correlation using a DHQ in young adult women who are likely to develop PD. The participants were enrolled from 2 universities and included 120 female college students a mean age of 20.4 y. The participants were assessed for the presence of PD according to the community periodontal index and were divided into two groups, the PD group and the non-PD group. Their dietary habits were investigated using a DHQ and the level of difficulty in chewing food was assessed. The PD group had a significantly lower nutrient intake of minerals, fat-soluble vitamins, water-soluble vitamins, and dietary fiber than the non-PD group. In terms of food groups, the PD group consumed significantly lesser amounts of green and yellow vegetables (GYV) than the non-PD group. Multivariate analysis revealed that the PD group had significantly lower intakes of vitamin E and GYV than the non-PD group. The PD group consumed significantly lesser amounts of hard foods than the non-PD group. In conclusion, young adult women who were evaluated for PD by a screening test had a significantly lower nutrient/food intake than those without a PD.
