Abstract:
ObjectiveTo evaluate the overall dietary intake of adult residents in Sijing Town, Songjiang District, Shanghai, and to explore the association between dietary health literacy and diet quality. MethodsA total of 1 280 adult residents were selected as the research subjects using a multi-stage sampling method, and face-to-face questionnaire surveys were administered on site. Dietary intake data were collected using a Food Frequency Questionnaire (FFQ), and the overall diet quality of the participants was evaluated based on the Chinese Healthy Eating Index (CHEI). Participants were divided into low- and high-CHEI groups according to the median CHEI score. Logistic regression models were used to examine the association between dietary health literacy and diet quality. ResultsThe median CHEI score for adults in the area was 63.68 points. Multivariate logistic regression analysis revealed that adults with lower dietary health literacy had lower CHEI scores and poorer overall diet quality compared to those with higher dietary health literacy (OR=1.435, 95%CI:1.132‒1.819). ConclusionThe overall diet quality of adult residents in this region requires improvement. There is a significant positive correlation between the level of dietary health literacy and CHEI scores, suggesting that enhancing dietary health literacy may be an important strategy to improve resident’ dietary quality.
