Objectives The purpose was to evaluate nutritional status, food security, and related health factors of older adults who were overweight or obese compared to those with a healthy weight. Methods Data from 2969 adults aged ≥60 years from NHANES 2011-2014 were analyzed. Participants were categorized by sex and body weight status as healthy weight (body mass index (BMI, kg/m2) 18.5-24.9), overweight (BMI 25-29.9), or obese (BMI ≥ 30); underweight individuals were excluded. Healthy Eating Index (HEI)-2015 scores and total usual micronutrient intakes from foods and dietary supplements were estimated using two 24-hour dietary recalls and the National Cancer Institute method. Nutritional biomarkers, including serum vitamin D, vitamin B-12, and methylmalonic acid, and cardiometabolic risk factors were also assessed. Results A substantial proportion of older adults (>30%) had intakes below Estimated Average Requirements (EAR) for calcium, magnesium, and vitamins C and D even with dietary supplements. Men and women with obesity had a higher prevalence of usual magnesium intakes
