Abstract
Background: Decline in mental health and cognitive status starts to show its sign during
middle-age and is affected by dietary factors, namely the polyphenols intake. Polyphenols have
received attention in improving health issues related to aging, including decline in mental health
and cognitive. The aim of this study is to determine the prevalence of poor mental health and
cognitive status among middle-aged adults and its predictors in relation to polyphenols intake.
Methods: Subjects’ food intakes were calculated by using dietary history questionnaire
and food frequency questionnaire for polyphenols. The subjects’ mental health and cognitive status
were measured by general health questionnaire-28 (GHQ-28) and Rey’s auditory verbal learning
test (RAVLT).
Results: More than 40% of middle-aged adults were identified as having signs of poor
mental health. A total of 67.9% of the subjects had poor cognitive status according to RAVLT
immediate recall. Hierarchical binary logistic regression indicated that fat intake was associated
with somatic symptoms for both men [adjusted odds ratio (AOR) = 1.04; P < 0.05] and women
(AOR = 1.06; P < 0.05). Intake of lignan (AOR = 1.071; P < 0.05) was associated with better RAVLT
immediate recall among women. Additionally, high cholesterol (AOR = 3.14; P < 0.05) was
associated with poor score of RAVLT delayed recall for women.
Conclusions: Early detection of poor mental health and cognitive is crucial to prevent
Alzheimer’s disease in old age.
