Association of daily coffee and tea consumption and metabolic syndrome: results from the Polish arm of the HAPIEE study

Abstract

PurposeThe aim of this study was to evaluate whether daily consumption of coffee and tea was associated with components and prevalence of metabolic syndrome (MetS) in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe cohort study.MethodsA cross-sectional population-based survey including 8,821 adults (51.4 % female) was conducted in Krakow, Poland. Coffee and tea consumption was evaluated using food frequency questionnaires. MetS was defined according to the International Diabetes Federation definition. Linear and logistic regression models were performed to estimate odds ratios and confidence intervals.ResultsAmong high coffee and tea consumers (3 or more cups/day), high prevalence of female gender, young age, medium–high educational and occupational level, high total energy intake, and smoking habit were found. High coffee drinkers had lower BMI, waist circumference, systolic and diastolic blood pressure, triglycerides, and higher HDL cholesterol than those drinking less than 1 cup/day. In contrast, high tea consumers had lower BMI, waist circumference, but not diastolic blood pressure, which was higher than low drinkers. After adjusting for potential confounding factors, both higher coffee and tea consumption were negatively associated with MetS (OR 0.75, 95 % CI 0.66, 0.86 and OR 0.79, 95 % CI 0.67, 0.92, respectively). Among specific components of MetS, high coffee consumption was negatively associated with waist circumference, hypertension, and triglycerides, whereas tea consumption with central obesity and fasting plasma glucose in women, but not in men.ConclusionsCoffee and tea consumption was negatively associated with MetS and some of its components.

Tea Consumption and Longitudinal Change in High‐Density Lipoprotein Cholesterol Concentration in Chinese Adults

“…Several observational studies have investigated the association between tea consumption and HDL‐C concentrations 24, 25, 26, 27, 28. The findings have been mixed.…”

“…The findings have been mixed. Some studies have reported no association between green or black tea and HDL‐C concentrations,26, 27, 28 whereas others have reported a significant positive association between tea consumption and HDL‐C concentration 24, 25. Of note, those observational studies were cross‐sectional study design, making it impossible to infer the temporal association between tea consumption and lipid profiles.…”

Coffee consumption and risk of the metabolic syndrome: A meta-analysis

“…Therefore, epidemiological studies have investigated the association between coffee consumption and the risk of MetS, although the results have been inconsistent. Some studies [22][23][24][25][26] have found that coffee consumption was inversely associated with the MetS, while other studies [27,28] or its components. In addition, the dose-response relationship between coffee consumption and MetS risk is still uncertain.…”

Prevalence and risk factors of hypertension among the bank employees of Western Maharashtra – a cross sectional study

“…Grosso et al have found that tea or coffee consumption was found to be negatively associated with hypertension. 28 This was more remarked for the coffee than tea. In contrast to this, present study had found positive and independent association of both tea and coffee with hypertension which was more marked for coffee and found to be highly significant.…”
