Introduction: This study aimed to identify dietary patterns (DPs) and their
association with successful aging (SA). Methods: A comparative cross-sectional
study was conducted among 579 elderly subjects recruited from four states in
Malaysia through a multistage random sampling method. SA was defined as having
no chronic illnesses, no functional limitation, normal global function, no depression,
a good quality of life and good self-perceived health. Information on dietary intake was
obtained using a diet history questionnaire. Cognitive functions were assessed using
the Mini Mental State Examination (MMSE), depressive symptoms using Geriatric
Depression Score-15 items (GDS-15) and a question regarding their perceived health
and quality of life. Activities of Daily Living (ADL) and Instrumental Activities of Daily
Living (IADL) questionnaires were used to determine functional status. DPs were
obtained using the principal component analysis (PCA) approach. An ordinal logistic
regression model was used to examine associations between DP scores and SA.
Results: Five DPs were identified namely ‘sweet foods-beverages’, ‘meat-vegetablesrice and noodles’, ‘local snacks-fish and seafood-high salt foods’, ‘fruits-legumes’, and
‘tropical fruits-oats’. A higher score for ‘tropical fruits-oats’ DP was associated with
SA [Adjusted OR=1.59 (95% CI: 1.08-2.32)]. However, the association diminished
when the model was adjusted for education level. Further analysis indicated that
this DP increased the chance of SA among those with secondary education and above
[Adjusted OR=2.43 (95% CI: 1.09–5.42)]. Conclusion: ‘Tropical fruits-oats’ DP is
associated with SA among elderly with secondary education and above. There is a
need to investigate DPs among those with lower education.
