Resum
Abstract: Background/Objectives: The nutritional habits of older adults are increasingly relevant to public health, particularly given the rising prevalence of obesity and its associatedchronic diseases. This study aims to analyze the relationship between the Healthy Eating Index (IASE) and Body Mass Index (BMI) in older adults in Spain, focusing on foodfrequency, dietary preferences, and socioeconomic factors influencing nutritional security. Methods: The study is part of the Eating Matters project, assessing food (in)securityin older adults across Andalusia and Catalonia between April 2022 and January 2024. A cross-sectional survey was conducted among 190 participants (≥65 years), recruited in primaryhealthcare centers. The questionnaire included three blocks: food insecurity assessment (FIES scale), diet quality with the Healthy Eating Index for the Spanish Population(IASE), and sociodemographic factors. Data analysis involved descriptive statistics, Pearson correlations, and logistic regression models to identify associated factors with overweightand obesity. Results: The average BMI was 28.5 kg/m2 (SD = 4.29), with 46.3% of participants classified as overweight and 32.1% as obese. A significant negative correlation(r = −0.79, p < 0.05) was found between healthy food consumption and BMI, while personal income showed a moderate positive correlation with adherence to a healthy diet(r = 0.42, p < 0.05). Logistic regression indicated that frequent consumption of processed meats and confectionery was a significant identify associated factors with overweight/obesity, with a model accuracy of 68% and sensitivity of 95%. Conclusions: Older adults with lower incomes and higher consumption of ultra-processed foods exhibited ahigher risk of obesity. These findings highlight the need for public policies promoting food accessibility and targeted nutrition education for older adults, including guidanceon balanced diets, adequate protein intake, and the prevention of sarcopenia, to encourage healthier dietary patterns in aging populations.
