  • Description: <jats:title>Abstract</jats:title> <jats:sec> <jats:title>Background</jats:title> <jats:p>Weight and appetite regulation have been associated with the expression and secretion of ATPase inhibitory factor 1 (IF1) and growth differentiation factor-15 (GDF-15), 2 potential biomarkers for age-related mitochondrial dysfunction. The aim was to explore the associations between these biomarkers and nutritional variables in the Multidomain Alzheimer Preventive Trial study.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods</jats:title> <jats:p>IF1 and GDF-15 plasma levels were quantified at 1-year follow-up. The nutritional status was measured using the Mini Nutritional Assessment (MNA) score variation between baseline and 1- and 2-year visits; appetite loss was extracted from the MNA. Bodyweight was measured every 6 months until the third year and then yearly until the fifth year of follow-up, and weight loss was established if the loss was greater than 5% or 10% within the past 6 or 12 months, respectively. Bidirectional associations of IF1 and GDF-15 levels with malnutrition, appetite, and weight loss were examined. The interactions between individual IF1 and GDF-15 with sex were explored.</jats:p> </jats:sec> <jats:sec> <jats:title>Results</jats:title> <jats:p>Four hundred and forty-eight participants had MNA data and 1 045 had weight loss data. All the associations between IF1 levels and the MNA score, appetite loss, and weight loss were nonsignificant. Higher GDF-15 levels were cross-sectionally associated with appetite loss at the first year of follow-up, and the GDF-15 highest quartile was associated with nearly 80% higher risks of weight loss over 4 years. Interactions between IF1 and GDF-15 levels, and between these 2 markers and sex were not significantly associated with the outcomes.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions</jats:title> <jats:p>GDF-15 plasma levels were related to key malnutrition criteria.</jats:p> </jats:sec>
