4-year incidence of protein-energy malnutrition
Achtergrond van het onderzoek
Protein-energy malnutrition (PEM) is a major problem in older adults worldwide. It is currently unknown whether poor diet quality is a risk factor for the long-term development of PEM. Therefore, this study aims to determine whether poor diet quality is associated with the incidence of PEM in community-dwelling older adults.
Data will be used of U.S. community-dwelling older adults aged 70-79 years of the Health ABC Study, who are free of PEM at baseline. By using Cox regression analyses, the associations of three indicators of diet quality, including the Healthy Eating Index, energy intake and protein intake, with 4-year incidence of PEM will be examined.

Onderzoeksopzet
Protein-energy malnutrition was defined as: a BMI <20 kg/m2 and/or involuntary weight loss ¡Ý5% in the preceding year. Protein-energy malnutrition was assessed annually, from baseline through the fourth follow-up examination.
Diet quality, energy intake and protein intake were determined at baseline using an interviewer-administered food frequency questionnaire.
