- Public TitleProtein intake not related to mid-thigh muscle area change
- Scientific TitleDietary protein intake is not associated with 5-year change in mid-thigh muscle cross-sectional area by computed tomography in older adults: the Health, Aging, and Body Composition (Health ABC) Study
- hypothesisA higher (animal) protein and a higher essential amino acid intake (especially leucine) are associated with less decline in mid-thigh muscle cross-sectional area over a 5-year period.
- Healt Condition(s) or Problem(s) studiedAged, Protein, Loss of muscle mass
- Inclusion criteriaData from the Health, Aging, and Body Composition (Health ABC) study were used. The Health ABC study is a prospective cohort study and investigates the association among body composition, weight related health conditions, and functional limitations in older adults. Between April 1997 and June 1998, 3075 well-functioning black and white men and women aged 70-79 were enrolled. Participants were recruited from a random sample of white Medicare-eligible residents and all of the black Medicare-eligible residents in the Pittsburgh, PA, and Memphis, TN, metropolitan areas. Subjects were eligible if they reported no difficulties in walking one-fourth of a mile, climbing up 10 steps, or performing basic activities of daily living; no history of active cancer in the 3 y prior to the study; planned to remain in the geographic area for 3y; and were not enrolled in lifestyle intervention trials. All participants gave written informed consent.
- Exclusion criteriaParticipants were excluded from the data-analyses if they had no good quality Computed Tomography (CT) data at year 1 (baseline) and year 6 of the HealthABC study and if they had no or no good quality dietary intake data (with a food frequency questionnaire)
