Implication

Cross-sectional analysis finds food choice motives correlate with diet quality in Korean adults, suggesting the need for tailored health-promotion interventions.

Key Points

To evaluate the associations between food choice motives and diet quality among Korean adults and determine whether these relationships vary by sex and age.
Analyzed cross-sectional online survey data from 1,829 Korean adults aged 20–64 years.
Assessed food choice motives using the 36-item Food Choice Questionnaire (yielding Health/Naturalness, Convenience/Price, and Mood/Sensory factors) and diet quality via the Nutrition Quotient for adults (NQ-2021).
Conducted multivariable linear regression adjusting for sex, age, BMI, and education level, evaluating effect modification via interaction terms.
Health/Naturalness motives were positively associated with diet quality (β = 9.03; 95% CI: 8.13 to 9.93).
Convenience/Price motives (β = -3.40; 95% CI: -4.55 to -2.25) and Mood/Sensory motives (β = -2.48; 95% CI: -3.57 to -1.40) were inversely associated with diet quality.
The inverse association for Convenience/Price motives was stronger in women than men (p-interaction = 0.022), with significant age-group interaction for Health/Naturalness (p-interaction = 0.002) and Mood/Sensory motives (p-interaction = 0.018).
