Abstract

Purpose

Aging adults from low-income residential areas were found to have poor nutritional status and mental health based on National Health and Morbidity Survey Malaysia (2015). Good nutrient intake contributes positively in averting these problems. Traditional Asian vegetables (ulam) are rich in polyphenols, antioxidants and fibres which could enhance nutritional status and mood state. This study intended to determine the relationship between habitual ulam intake and nutritional status, mood state and cognition among 252 aging Malaysian adults aged 45–80 years from the low-income residential areas in Klang Valley, Malaysia.

Design/methodology/approach

It was a cross-sectional study that used convenient sampling. Advertisement and invitation letters were sent to three selected community centres in Klang Valley prior to data collection. Informed consent was obtained prior to the collection of socio-demographic data. Anthropometric measurement was performed as per standard protocols. Validated surveys were conducted to obtain information on ulam consumption, mood state and cognitive status using validated food frequency questionnaires, Profile of Mood State and Mini-Mental State Examination questionnaires, respectively.

Findings

The average of ulam intake was 20.5 ± 2.5 g/day (½ serving daily). Habitual ulam intake was associated with lower waist circumference (R2 = 0.166, β = −0.216, p < 0.01), better MMSE scores (R2 = 0.337, β = 0.128, p < 0.05), less anger (R2 = 0.081, β = −0.116, p < 0.05), less tension (R2 = 0.139, β = −0.204, p < 0.01) and positive total mood disturbance (R2 = 0.095, β = 0.164, p < 0.05) after adjustment for gender, age, energy intake, total fruits and vegetables (non-ulam) consumption. The ulam intake at 100th percentile (=30g/day) associated to a better nutritional status, mood state and cognitive status in comparison to 25th percentile (<7.9 g/day) (p < 0.05).

Originality/value

Findings from this research would recommend people to consume not less than 1 serving of ulam everyday in order to have improved nutritional status, mood and cognition; nonetheless, future studies are required to clarify the causal mechanism concerning this relationship.
