Dietary Intake, Attitudes toward Healthy Food, and Dental Pain in Low-Income Youth

Few studies have examined the relation between food consumption and related attitudes and dental pain among children. The objective of this study is to examine the associations of healthy and unhealthy food items, attitudes toward healthy food, and self-efficacy of eating healthy with dental pain among children. A cross-sectional analysis was performed using child survey data from the Texas Childhood Obesity Research Demonstration (TX CORD) project. Fifth-grade students (n = 1,020) attending 33 elementary schools in Austin and Houston, Texas, completed the TX CORD Child Survey, a reliable and valid survey instrument focused on nutrition and physical activity behaviors. All nutrition questions ask about the number of times food and beverage items were consumed on the previous day. Dental pain was reported as mouth or tooth pain in the past 2 wk that made their mouth hurt so much that they could not sleep at night. Mixed-effects logistic regression models were used to test the association between 10 unhealthy food items, 9 healthy food items, 2 health attitudes, and self-efficacy with dental pain. All models controlled for sociodemographic variables. In total, 99 (9.7%) students reported dental pain. Dental pain was associated with intake of the following unhealthy items: soda, fruit juice, diet soda, frozen desserts, sweet rolls, candy, white rice/pasta, starchy vegetables, French fries/chips, and cereal (adjusted odds ratio [AOR], 1.27–1.81, P < 0.01). The intake of other vegetables (AOR, 1.56; P < 0.01), a healthy item, and the attitude that healthy food tastes good (AOR, 1.59; P = 0.04) were also positively associated with dental pain. The attitude of eating healthier leads to fewer health problems (AOR, 0.50) and self-efficacy for healthy eating (AOR, 0.44) were negatively associated with dental pain (P < 0.01). Interventions should focus on improving oral health by reducing intake of unhealthy foods and educating children and families on the importance of diet as a means of reducing dental caries.
