Background. The changes in consumers’ eating habits are one of the most important factors affecting the consumption of selected foods. The most important factors for bakery products consumers are freshness, taste, price, durability, composition, and country of origin. Objective. The aim of this study was to monitor changes in selected anthropometric characteristics in women from the general population in Slovakia, after 6 weeks of bakery products consumption. Material and Methods. The study was conducted on healthy adult women from the general population (n=78), who were divided into four subgroups (“gluten” group, “gluten-free” group, “whole-grain” group and “control” group). The intervention dose consisted of a different combination of several types of bakery products (bread, pastries, soft pastries) within the individual weeks of consumption, while the intervention lasted 6 weeks, women consumed 150-200 grams per day. Anthropometric characteristics were measured by body composition analyser InBody 720 (Biospace Co. Ltd., Seoul, Republic of Korea), which works on the principle of bioelectrical impedance analysis. We also used the Lookin´Body 3.0 software to process the results. The collected data from these measurements were evaluated statistically and graphically in Microsoft Office Excel 2010 (Los Angeles, CA, USA). The levels of statistical significance were set at P<0.05 (*); P<0.01 (**); P<0.001 (***). Differences among subgroups of probands were tested with Pared Student t-test. Results. The amount of fat mass (FM) in the participants changed along a similar curve as their body weight. After the 6-week intervention, there was a slight decrease in FM with statistical significance (P<0.01). In the third measurement, i.e., two months after the intervention, there was an increase in the amount of FM, but without statistical significance. Fat free mass (FFM) values in women increased very slightly after 6 weeks of consumption and remained approximately at the same level two months after the intervention (without statistical significance). We noted the most significant changes in the visceral fat area (VFA) parameter, which had a steadily increasing tendency. Changes in VFA values were statistically significant after the 6-week intervention (P<0.01) and also after two months of the intervention (P<0.05). Conclusions. Changes in body composition in women were noted already after 6 weeks of bakery products consumption, especially in the FM, FFM, VFA and partially BMI parameters, but no changes were recorded in the WHR parameters during the entire duration of the study. One of the most significant results is the finding that there was an increase in VFA when consuming all types of bakery products (gluten, gluten-free and whole grain).

Background. Obesity is a global epidemic and belongs to major risk factors for the most prevalent diseases. Anthropometric measures are simple, inexpensive, non-invasive tools to diagnosis obesity and to assess the risk of morbidity and mortality. The most widely used are body mass index (BMI), waist circumference (WC), waist-to-hip (WHR) and waist-to-height ratios, visceral fat area (VFA), body fat (BFP) and a new body shape index (ABSI). Objective. The aim of this study was to examine the usefulness of the ABSI in obesity diagnosis compared with other anthropometric parameters like WC, WHR, BMI, VFA, and BFP. We also compared the predictability between ABSI and above mentioned common anthropometric indices. Material and methods. The study group was composed of 236 university students. Body height, weight, WC was measured and BMI, WHR, ABSI and ABSI z-score were calculated. The anthropometric measurements were made by using InBody 720 (Biospace Co. Ltd., Seoul, Republic of Korea). Body composition, especially VFA, BFP, FFM was diagnosed by multifrequency bioelectrical impedance analysis. We evaluated the collected data statistically and graphically in Microsoft Office Excel 2010 (Los Angeles, CA, USA). Statistical analyses were performed using the program STATISTICA Cz version 10. Results. The diagnosis of obesity among participants according to anthropometric measures and indices showed considerable differences. We found that obesity was diagnosed according to waist circumference in 31% of participants. According to BMI 20.3% of subjects were overweight and 5.1% obese. With increasing BMI values, the values of WC, WHR and VFA also increased linearly. According to visceral fat area 11.4% of participants were in the risk obese group and by ABSI mortality risk there were 22% of subjects with high risk (4.8% and 28.3% for men and women, respectively) and 19.1% with very high risk (11.1% and 22% for men and women, respectively). VFA and BFP values increased with increasing risk of mortality, and in men also waist circumference values. When evaluating the ABSI in relation to BMI, the U-shaped curve was confirmed and in the case of WC the J-shaped curve. The FFM evaluation showed that the very low ABSI mortality risk group reached the highest values of this parameter and the lowest values showed the average mortality risk group, not only in the study group but also in male and female groups. Conclusions. Our findings suggest the relevance of ABSI to screen at-risk population.

Background. Fat and fat-free/muscle mass and their ratio reflecting the possible presence of obesity or sarcopenic obesity are important in assessing body composition. Objective. The aim of the work was to assess the use of fat and fat-free mass and their ratio in the diagnosis of sarcopenic obesity, as well as correlations with selected anthropometric, somatic and biochemical parameters and indices. Material and Methods. The object of the study was a group of 201 women (20-68 aged) randomly selected from the population without the presence of a serious disease or without the use of medication. Body composition was assessed by the MFBIA method (InBody 720). We used the ratio of fat to fat-free mass (FM/FFM) to define sarcopenic obesity. A Biolis 24i Premium biochemical analyzer was used to determine biochemical parameters. Results. Using FM and FFM values and their mutual ratio, we identified women with a healthy body weight (28.9%), obese women (58.2%) and women with sarcopenic obesity (12.9%). Values of anthropometric parameters (body weight, BMI, WC, WHR, WHtR, BAI, FM (kg, %), FMI, VFA, FFM (kg), FFMI, SMM (kg), SMMI, ICW, ECW, TBW, CHC, HC), with the exception of FFM (%), SMM (%) and TBW (%), increased significantly with increasing FM/FFM values, so the highest values were found in subjects with sarcopenic obesity. In the case of biochemical parameters, with increasing FM/FFM values, the values of T-CH, LDL, TAG, GLU, hs-CRP, UA, systolic and diastolic blood pressure also increased, so the highest values were again found in women with sarcopenic obesity. HDL values, on the contrary, decreased. FM/ FFM had the strongest positive association with the proportion of fat mass on body weight (r=0.989), then with FMI (r=0.980), FM (r=0.965), VFA (r=0.938), WHtR (r=0.937), BMI (r=0.922), WC (r=0.901. We found the strongest negative association with the proportion of FFM on body weight (r=-0.989), the proportion of total body water (r=-0.988) and the proportion of skeletal muscle mass (r=-0.987). Conclusions. FM/FFM correlates excellently with FM and VFA and can be implemented to diagnose obesity. In order to comprehensively evaluate the state of health and body composition, the proportionality of not only fat, but also fat-free/ muscle mass should be analyzed, because it turns out that a negative impact on health and survival is associated not only with an excessive amount of adipose tissue, but also with a lower muscle mass.

Background. Chronic obstructive pulmonary disease (COPD) is an airway inflammatory disease caused by inhalation of toxic particles, mainly cigarette smoking, and now is accepted as a disease associated with systemic characteristics. Objective. The aim of this work was to investigate and compare selected biochemical parameters in patients with and without COPD. Material and Methods. Observation group consisted of clinically stable patients with COPD (n = 60). The control group was healthy persons from the general population, without COPD, who were divided into two subgroups – smokers (n = 30) and non-smokers (n = 30). Laboratory parameters were investigated by automated clinical chemistry analyzer LISA 200th. Results. Albumin in our measurements showed an average value of 39.55 g.l-1 in the patient population; 38.89 g.l-1 in smokers and in non-smokers group 44.65 g.l-1. The average value of pre-albumin in the group of patients was 0.28 ± 0.28 g.l-1 and 0.30 ± 0.04 g.l-1 in smokers group. The average value of the orosomucoid in patients was about 1.11 ± 0.90 mg.ml-1. In the group of smokers, the mean value of orosomucoid was 0.60 ± 0.13 mg.ml-1. The level of C-reactive protein (CRP) in the patient group reached an average value of 15.31 ± 22.04 mg.l-1, in the group of smokers was 5.18 ± 4.58 mg. l-1. Prognostic inflammatory and nutritional index (PINI) in the group of patients showed a mean value of 4.65 ± 10.77 and 0.026 ± 0.025 in smokers. Conclusions. The results of this work show, that the values of index PINI in COPD patients are significantly higher than in smokers (P <0.001). This along with other monitored parameters indicative inflammation as well as a catabolic process that occurs in the organism of patients with COPD.

Wprowadzenie. Przewlekła obturacyjna choroba płuc (POChP) jest chorobą zapalną dróg oddechowych spowodowaną inhalacją toksycznych związków chemicznych, pochodzących głównie z palenia papierosów, która charakteryzowana jest jako choroba ogólnoustrojowa. Cel. Celem niniejszej pracy było oznaczenie we krwi chorych na POChP wybranych parametrów biochemicznych stanu zapalnego oraz porównanie ich stężenia w grupie zdrowych ludzi bez POChP.0 Materiał i metody. Grupa badana składała się z klinicznie stabilnych pacjentów z POChP (n = 60). Grupę kontrolną stanowili zdrowi pacjenci z populacji generalnej, bez POChP, którzy zostali podzieleni na dwie podgrupy – palaczy papierosów (n = 30) i niepalących (n = 30). Parametry biochemiczne oznaczano z wykorzystaniem automatycznego analizatora LISA 200. Wyniki. Średnie stężenie albumin w grupie chorych wynosiło 39.55 g.l-1 ; w grupie zdrowych palących 38.89 g.l-1 a w grupie zdrowych niepalących 44.65 g.l-1. Średnie stężenie pre-albuminy w poszczególnych grupach pacjentów i zdrowych palących wynosiło odpowiednio 0.28 ± 0.28 g.l-1 oraz 0.30 ± 0.04 g.l-1. Stężenie orosomukoidu w grupie chorych wynosiło 1.11 ± 0.90 mg.ml-1. W grupie palących zdrowych osób średnio 0.60 ± 0.13 mg.ml-1. Stężenie białka Creaktywnego (CRP) w grupie chorych na POChP wynosiło 15.31 ± 22.04 mg.l-1, a w grupie palących 5.18 ± 4.58 mg. l-1. Prognostyczny wskaźnik odżywienia i stanu zapalnego - PINI (Prognostic Inflammatory and Nutritional Index) w grupie pacjentów wynosił średnio 4.65 ± 10.77 a w grupie osób palących 0.026 ± 0.025. Wnioski: Wyniki niniejszych badań wykazały, że wartości PINI u pacjentów z POChP były statystycznie wyższe (p <0,001) niż w grupie osób palących. Uzyskane wyniki wraz z innymi monitorowanymi parametrami świadczą o stanie zapalnym jak również o procesie katabolicznym, który występuje w organizmie pacjentów z POChP.
