Introduction. There is increasing interest in modifiable factors that may be effec-
tive in both the prevention and treatment of sarcopenia. Although there is a
growing evidence of the importance of nutrition in the treatment of sarcope-
nia, studies examining the relationship between nutrient intake and sarcopenia
in older adults are limited. The aim of this study was to examine the association
between nutrient intake and sarcopenia in older adults.
Methods. The case-control observational study included 115 older adults (≥
65 years), 26 of whom were classified as sarcopenic. Sarcopenia was assessed
according to the European Working Group on Sarcopenia in Older People
(EWGSOP) diagnostic criteria. Habitual dietary intake was assessed with the
3-day weighed dietary record over two weekdays and one weekend day. The
weight of food intake in grams was converted into energy, macronutrient and
micronutrient amounts using an online OPEN (Open Platform for Clinical Nu-
trition) dietary assessment tool. The mini nutritional assessment (MNA) was
used to assess the nutritional status. Differences in nutrient intake and nutri-
tional status between the sarcopenic and non-sarcopenic groups were evaluat-
ed. Risk factors were determined using logistic regression with sarcopenic sta-
tus as the outcome.
Results. Seven nutrients (n-3 fatty acid, vitamin D, vitamin K, vitamin C, vita-
min B1, vitamin B7, and vitamin B9) were all statistically significantly lower in the
sarcopenic compared to the nonsarcopenic group (p < .05). An increased risk
of sarcopenia (R2 = .756) was found in older adults with low dietary intakes of
n-3 fatty acids. After accounting for possible covariates, the evidence for an as-
sociation between n-3 fatty acid and sarcopenia is partially explained by age,
body mass index, presence of diabetes mellitus, hypertension, and physical ac-
tivity level.
Discussion and Conclusions. Sarcopenic older adults differed in terms of intake of
seven nutrients compared with non-sarcopenic older adults. Adequate intake
in some of these nutrients have been repeatedly shown to be valuable in pre-
serving muscle mass and protecting against normal decline in the elderly, both
in randomized controlled trials and in cohort analyses. Given that nutrition may
influence the development of sarcopenia, nutrition intervention may represent
a feasible measure for preventing or postponing age-related decline in muscle
mass and function.
