Objective
To estimate the reliability and validity of the Nutrition Literacy Assessment Instrument for Parents (NLit-P) and to investigate relationships between parental nutrition literacy, parental and child BMI, and child diet quality (Healthy Eating Index, HEI).
Methods
Cross-sectional study of 101 parent-child dyads which collected measures of socioeconomic status, nutrition literacy, 2–24 hour child diet recalls, and BMI. Reliability of NLit-P was assessed by confirmatory factor analysis. Pearson correlation and multiple linear regression was used.
Results
Fair to substantial reliability was seen across 5 NLit-P domains, while Pearson correlations support concurrent validity for the NLit-P related to child diet quality and parental income, age, and educational attainment (p<0.001). For every 1% increase in NLit-P, there was a 0.51 increase in child HEI (R2=0.174; p<0.001).
Conclusions and Implications
The NLit-P demonstrates potential for measuring parental nutrition literacy, which may be an important educational target for improving child diet quality.
