| description | Introduction: Individual food consumption has health implications and direct and indirect environmental impacts. However, knowledge of the determinants of adherence to sustainable healthy diets is still scarce. Purpose: Analyze the influence of sociodemographic factors (sex, age, marital status, household composition, education, and urbanization degree), body mass index (BMI), physical activity, and diet quality (nutrient adequacy ratio – NAR) on the adherence to the Sustainable HEalthy Diet (SHED) Index and its sub-scores among Portuguese adults. Materials and methods: Data for this cross-sectional study were obtained from a convenience sample of adults through the completion of a self-reported questionnaire, including sociodemographic information, adherence to the SHED Index, physical activity level (International Physical Activity Questionnaire), and dietary intake (semi-quantitative food frequency questionnaire). Multivariate linear regressions models were used to analyze the associations between factors and the SHED Index and its sub-scores. Results: A total of 347 participants (64.6 % women) with a median age of 27 years old (P25:20; P75:50) were included. Multivariate regression showed an association of sex (Bmale = −4.286,p < 0.001), age (B = 0.263,p < 0.001), urbanization degree (Brural = 2.465,p = 0.034), and education (Bsecondary = 4.244,p = 0.021;Bcollege/university = 5.821,p = 0.001) with SHED Index scores. Furthermore, sex and age were associated with most sub-scores, marital status with Buy Fruits Vegetables and Water sub-scores, physical activity with Water sub-score, and both NAR and education with Healthy Eating sub-score. Conclusions: Findings suggest that sex, age, urbanization degree, and education level are associated with adherence to a sustainable healthy diet. Physical activity and diet quality were also shown to be associated with the SHED Index sub-scores of Water and Healthy Eating, respectively. |
