Abstract: Key summary pointsAim To investigate how food and dietary intakes, protein daily distribution and source were associated with appendicular lean mass (ALM)/m(2) in the oldest-old community-dwelling men. Findings ALM/m(2) was associated with total protein intake, source and distribution as well as fruit and vegetable intakes. Message Not only protein intake, but also source and distribution as well as healthy overall diet characterized by abundant amounts of fruits and vegetables were important in maintaining muscle mass in the oldest-old men in our study. Purpose We explored how food and dietary intakes, protein daily distribution and source are associated with appendicular lean mass (ALM)/m(2) of the oldest-old community-dwelling men. Methods Cross-sectional analyses of Helsinki Businessmen Study (HBS, mean age 87 years) participants who came to clinic visit in 2017/2018. Nutritional status, physical performance and fasting blood samples were measured. Food and dietary intakes were retrieved from 3-day food diaries. Body composition was measured and appendicular lean mass (ALM) per m(2) was dichotomized as ALM/m(2) <7 kg/m(2) and >= 7 kg/m(2). Differences between lower and higher ALM were analyzed using t test or Mann-Whitney U test. Analysis of covariance was used to investigate independent associations with ALM/m(2). Results Random sample of 130 participants took part in the medical examinations, 126 returned food diaries, and 102 underwent DXA-scan. ALM/m(2) was associated with total protein (p = 0.033), animal protein (p = 0.043) and meat protein (p = 0.033) intakes. Protein distribution between daily meals differed at lunch; those with higher ALM/m(2) ate more protein (p = .047) at lunch. Consumption of fruits, vegetables (p = 0.022) and meat (p = 0.006) was associated with ALM/m(2). Conclusion Protein intake, source and distribution as well fruit and vegetable intakes were associated with higher ALM in oldest-old men. Study registration The study is registered with ClinicalTrials.gov identifier: NCT02526082.
