Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Middle-aged subjects with signs of poor mental health and cognitive status were randomly assigned to received either polyphenols-rich tropical fruit juice TP 3-in-1 (TM) or placebo. A total of 1500 ml/day (divided for 3 intakes per day) of polyphenols-rich TP 3-in-1 juice or placebo would be taken by the subjects for 3 times per week. Study was conducted for a total of 10 weeks. Changes on subjects' mental health and cognitive status was measured during baseline, week 5 and after the supplementation ended. Additionally, measurement on oxidative stress and metabolic changes was measured throughout the intervention period. Researcher, who was a PhD candidate, would send the beverages on a weekly basis to the subjects' houses. Data collection during baseline, week 5 and by the end of intervention period was conducted at Clinical Trial Ward, UKM Medical Centre.

Comparator / control treatment
TP 3-in-1 juice is a polyphenols-rich tropical fruit juice, which was developed by a research group from Centre for Healthy Aging and Wellness (H-Care), Universiti Kebangsaan Malaysia. The placebo beverage contained no juice or natural polyphenol but was formulated to look and taste like TP 3-in-1™ juice and to provide the same energy content. A total of 1500 ml/day (divided for 3 intakes per day) of polyphenols-rich TP 3-in-1 juice or placebo would be taken by the subjects for 3 times per week. Study was conducted for a total of 10 weeks.

Statistical methods / analysis
Sample size was calculated by using the formula by Zhong (2009) with 80% power and 95% level of confidence. Additionally, mean difference and standard deviation values of 3.67 and 2.78, respectively, were obtained from a previous study by Gunstad et. al (2006) in order to calculate the sample size. After taking into consideration 20% droupout rate, the calculated sample size was 11 for each group.
Repeated measures analysis of variance (ANOVA) was carried out to determine the effects of polyphenols rich TP 3-in-1™ juice consumption at baseline, week 5 and week 10 (time effect), group effect and interaction effect.
