“…This study shows that the intake of total polyphenols in the current study (994.6 ± 557.7 mg/day) was lower than those reported in other studies. It was reported that the intake of total polyphenols among subjects aged 60 years and above was 2770.7 ± 1552.4 mg/day (24). Additionally, a study reported that the intake of total polyphenols among 10,477 individuals aged 45 to 69 years of urban population in Poland was 1756.5 ± 695.8 mg/day (25).…”

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.

“…Spearman’s rho and Kendall’s Tau-b analysis indicated that there was a significant positive correlation between polyphenol intake estimated from FFQ and reference method ( r = 0.41, P < 0.001; r = 0.28, P < 0.001). For Bland-Altman plot, 95.7% of scattered plot fell within ± 1.96 SD limits of agreement revealed that there was good agreement between the two methods used (9).…”

“…Sample size was calculated by using the formula by Cochran (8) with 8% level of accuracy of the mean with 95% certainty. Mean of polyphenols intake of 2770.7 (1552.4) mg/day were taken from a previous study by (9). After taking into consideration 20% dropout rate, the sample size calculated was 227.…”

“…The amount was then converted to weight in grams for polyphenols analysis. FFQ for polyphenols has been validated in a previous study by Suzana et al (9) against 2-day diet records and diet history questionnaire. Spearman’s rho and Kendall’s Tau-b analysis indicated that there was a significant positive correlation between polyphenol intake estimated from FFQ and reference method ( r = 0.41, P < 0.001; r = 0.28, P < 0.001).…”

BackgroundResearches on polyphenols have been the interest of few parties due to its possible roles in the prevention of obesity. However, studies regarding this topic are still limited. Therefore, this study was conducted to examine the relationship between the intake of polyphenols with adiposity indices among middle-aged adults.MethodsThis cross-sectional study involved 227 adults aged 40 to 59 years at low-cost housing flats in suburban area of Cheras, Kuala Lumpur. Data collection involved food frequency questionnaire (FFQ) for polyphenols and international physical activity questionnaire (IPAQ). Subjects were measured for anthropometric parameters including height, weight, waist and neck circumferences (NC), and body fat percentage. The polyphenol intake from the diet was estimated using local polyphenol database built according to PHENOL-EXPLORER.ResultsThe average intake of polyphenol of subjects was 1815 (672) mg/day. The main food sources of polyphenol were coffee with milk, followed by chocolate milk and red beans. A higher polyphenol intake according to quartile was significantly associated with a lower neck circumference (χ2 = 8.30, P = 0.040), waist circumference (χ2 = 8.45, P = 0.038) and body fat percentage (χ2 = 8.06, P = 0.045). Binomial logistic regression analysis showed that the association remained significant for the neck circumference (P = 0.032), after controlling for age, household income, energy intake and physical activity level. More subjects with normal NC had higher intake of polyphenols (50th percentile and above). In contrast, subjects with high NC showed lower percentiles of polyphenols intake (50th percentile and below).ConclusionThe result showed that polyphenol intake was associated with neck circumference and thus it can be suggested that polyphenol intake is associated with obesity.
