OBJECTIVES: The universally recognized indicator of nutritional status, BMI, has some shortcomings, especially in detecting overweight and obesity. A relatively recently introduced normal weight obesity (NWO) describes a phenomenon when individuals are found to have normal weight as indicated by BMI but have an elevated percentage of body fat. Normal weight obese individuals face a higher risk of developing metabolic syndrome, cardiometabolic dysfunction and have higher mortality. No studies have been previously performed which would map NWO in Brno, Czech Republic. METHODS: In a sample of 100 women from Brno, we assessed the percentage of normal weight obese individuals using bioelectric impedance analysis (BIA) - three different analyzers were utilized: Tanita BC-545 personal digital scale, InBody 230 and BodyStat 1500MDD. Also, a caliperation method was used to estimate body fat percentage. Various body fat percentage cut-off points were used according to different authors. RESULTS: When the 30% body fat (BF) cut-off was used, up to 14% of the women in our sample were found to be normal weight obese. When the sum of skinfolds or the 35% BF cut-off point are selected as a criterion for identifying normal weight obesity (NOW), only 1 of 100 examined women was identified as normal weight obese; at the 35% BF cut-off, BodyStat analyzer categorized no women as normal weight obese. Also, when the 30% BF or 66th percentile BF cut-off points were utilized, BodyStat identified pronouncedly fewer women from our sample to be normal-weight obese than the two other analyzers. CONCLUSIONS: On a pilot sample of Czech women, we demonstrated that depending on the selected cut-off (there is no clear agreement on cut-off points in literature), up to 14% of the examined women were found to be normal weight obese.

OBJECTIVE: The aim of the study was to evaluate alcohol consumption in a representative sample of the population of the city of Brno, as part of research on cardiovascular risk factors. METHODS: Cross-sectional survey on a sample of 2,160 randomly selected residents 35-65 years old was carried out. For the invited volunteers who became a part of the investigation, alcohol consumption was determined in a controlled, face to face interview structured in accordance with a special questionnaire form. The frequency of alcohol consumption during the previous year was determined, in more detail during the last month (including quantification using "units of alcohol", their normal and maximum level of drinking, and any association between alcohol consumption and meals), and during the last week in the form of a complete, beverage specified and quantified 7-day recall period. Typical patterns of alcohol consumption were explored by the means of cluster analysis. RESULTS: During the past 12 months, 90.0% of the men and 79.0% of the women had consumed alcohol, the rest can be considered abstinent. The most commonly reported frequency was 2-4 times per week (35.6% of the men), or 1-3 times per month (22.8% of the women). Daily or almost daily consumption was reported by 24.8% of the men and 12.8% of the women. The number of units of alcohol consumed usually on one occasion amounts to an average of 3.88±4.80 for the men and 2.25±1.39 for the women, but the amount most often cited by both sexes was 2 drinks (36.4% of the men and 40.4% of the women). The largest amount consumed on any occasion during the last 30 days was 5 or more units in 69.3% of the men, and in 33.9% of the women it was 4 or more units (this amount of alcohol leads to a blood alcohol concentration (BAC) of 0.08, the border of drunkenness). In 19.9% of the men and 7.5% of the women, this border was exceeded more than 5 times in the past month. Only 14.7% of the men and 10.3% of the women reported that the majority of their alcohol consumption occurs with food; on the contrary, 64.3% of the men and 77.6% of the women drinkers drink it either always without food or only rarely with it. During the past week, 81.6% of the men and 63.4% of the women drank alcohol (p<0.001, chi-square). The average value of consumption for one man was 11.57±11.91 doses, and for one woman 4.68±6.38 doses per week (p<0.001, t-test). A total of 17.8% of the men exceeded the limit of 21 doses per week, and 7.4% of the women exceeded 14 doses/week. After converting the weekly consumption into the number of units of alcohol per week expressed in litres per year, the total average consumption was 5.01±6.36 litres; for the men 7.26±7.62 litres and for the women 3.02±4.08 litres of pure alcohol per person annually. Consumption during the week was not uniform (p<0.001, ANOVA), with the highest occurring on Saturday, followed by Friday. The men mostly drank beer (62.9% of the total volume of alcohol), the women wine (68.6%). The cluster analysis identified 5 clusters of respondents, based on a set of alcohol consumption variables, as follows: very heavy drinking (1.6% of the respondents who drink alcohol); heavy drinking (8.8%); binge drinking (6.3%); moderate drinking (31.1%); and occasional drinking (52.3%). CONCLUSIONS: The results show a relatively high consumption of alcohol in the examined group. The recommended weekly limits were exceeded by only a small portion, but that consumption had a binge character. Conversion into a form allowing comparison with conventional national statistics shows a significantly lower consumption than these reported statements. Overall, men consume significantly more alcohol than women.

OBJECTIVE: Manual office blood pressure (BP) is still recommended for diagnosing hypertension. However, its predictive value is decreased by errors in measurement technique and the white-coat effect. The errors can be eliminated by automated office BP (AOBP) measurement taking multiple readings with the participant resting quietly alone. Therefore, use of AOBP in clinical practice requires a threshold value for hypertension diagnosis. The aim of the present study was to determine an AOBP threshold corresponding to the 140/90 mmHg manual office BP using data from a large random population sample. METHODS: In 2145 participants (mean age 47.3 ± 11.3 years) randomly selected from a Brno population aged 25-64 years, BP was measured using manual mercury and automated office sphygmomanometers. RESULTS: Manual SBP (mean difference 6.39 ± 9.76 mmHg) and DBP (mean difference 2.50 ± 6.54 mmHg) were higher than the automated BP. According to polynomial regression, automated systole of 131.06 (95% confidence interval 130.43-131.70) and diastole of 85.43 (95% confidence interval 85.03-85.82) corresponded to the manual BP of 140/90 mmHg. Using this cut-off, the white-coat hypertension was present in 24% of participants with elevated manual BP, whereas 10% had masked hypertension and 11% masked uncontrolled hypertension. In individuals with masked uncontrolled hypertension, only AOBP was associated with the urinary albumin-creatinine ratio, whereas there was no association with manual BP. CONCLUSION: AOBP of 131/85 mmHg corresponds to the manual BP of 140/90 mmHg. This value may be used as a threshold for diagnosing hypertension using AOBP. However, outcome-driven studies are required to confirm this threshold.
