Little is known about interrelationships among nutrition knowledge, attitude, dietary intake, and body satisfaction, which are important variables that play a role in nutrition education interventions. This paper aims to focus on these interrelationships.

Students (n=279; 20.12±1.75SD years) enrolled at a large northeastern US university took an online survey. The survey contained a nutrition knowledge scale, attitude scale, food frequency scales, body areas satisfaction subscale, and demographic characteristics questions. To determine relationships, correlation coefficients were computed, along with forward stepwise regression to identify predictors of each study measure.

Data were collected from a non‐probability sample in one geographical area at one time point.

In males, significant positive correlations were found between fruit/vegetable servings and attitudes, knowledge, body satisfaction; and between knowledge and attitudes. Stepwise multiple regression analysis found fruit/vegetable servings and percent calories from fat significantly predicted attitudes, while in females attitude was a significant predictor variable for knowledge, fruit/vegetable servings, and percent of calories from fat. Among females, significant positive correlations occurred between attitudes and knowledge, and fruit/vegetable servings and attitudes.

Nutrition and health interventions should incorporate lessons that work to improve one's attitudes toward nutrition. Interventions targeted to males should aim to increase nutrition knowledge, while interventions targeted to females should focus on nutrition knowledge and attitudes.

This paper expands on what is known about young adults and key cognitive factors that influence their nutrition knowledge, attitudes, dietary intake, and body satisfaction. Nutrition educators can utilize the study findings to inform future nutrition interventions.
