Brief Summary

The main aims of the work: Analysis of the concentration of selected pro-inflammatory parameters in blood serum and saliva of people with different distribution of subcutaneous and visceral adipose tissue. Analysis of metabolic obesity biomarkers in saliva and blood serum. Evaluation of new diagnostic methods for the early determination of the risk of metabolic obesity and its complications. Based on the inclusion and exclusion criteria the observational study was conducted among 119 people (79 women and 41 men). Study group included 79 people (48 women and 31 men with obesity), and control group included 41 people (31 women and 10 men with normal body weight). The study consisted of three visits. The first included qualification for the study, body composition measurements, ankle-brachial index test and completing the questionnaires and 3-day nutrition diaries. At the second visit blood was collected to conduct the morphological test. At the third visit saliva was collected to determine the proinflammatory cytokine and adipokine concentration.

Outcome Measures

Primary Outcomes (9)

  • Analysis of the concentration of selected pro-inflammatory cytokines and adipokines in the saliva of patients with normal and excess body weight (obesity).

    Analysis of the concentration in saliva of MMP-9, MMP-2, IL-6, TNF-α, resistin, IL-1β, IL-23 in patients with normal and excess body weight (obesity).

    24 months (analyzes were performed throughout the study period).

  • Analysis of the concentration of selected pro-inflammatory cytokines and adipokines in the blood serum of patients with normal and excess body weight (obesity).

    Analysis of the concentration in saliva of adiponectin, IL-6,TNF-α, MMP-9, MMP-2, resistin, IL-1β, IL-23 in patients with normal and excess body weight (obesity).

    24 months (analyzes were performed throughout the study period).

  • Analysis of body composition of people with normal and excess body weight (obesity).

    In order to determine the body composition of the study participants, an electrical bioimpedance body composition analysis was carried out using the InBody 270 (South Korea, Seoul) device, which enabled the assessment of the following parameters: total body fat percentage, total lean body mass percentage, total body fat mass, total skeletal muscle mass, total body water (L), extracellular (L) and intracellular (L) water.

    24 months (analyzes were performed throughout the study period).

  • Analysis of body composition and adipose tissue redistribution of people with normal and excess body weight (obesity).

    In order to determine the body composition of the study participants an electrical bioimpedance body composition analysis was carried out using the device: BioScan 920-2 (Great Britain, Essex), which enabled the assessment of the following parameters: total body fat percentage, total lean body mass percentage, total body fat mass, total skeletal muscle mass, total body water (L), extracellular (L) and intracellular (L) water. Also, the area of adipose tissue in the abdominal cross-section was determined: visceral (VAT- Visceral Adipose Tissue) and subcutaneous (SAT- Subcutaneous Adipose Tissue), and visceral to subcutaneous fat ratio (VAT / SAT ratio).

    24 months (analyzes were performed throughout the study period).

  • Analysis of differences in the eating habits of people with normal and excessive body weight (obesity).

    All participants completed "Beliefs and Eating Habits Questionnaire" created by Behavioral Conditions of Nutrition Team Committee of Human Nutrition Science, Polish Academy of Science.

    24 months (analyzes were performed throughout the study period).

  • Analysis of differences in the diet of people with normal and excessive body weight (obesity).

    All participants completed 3-day Nutrition Diary.

    24 months (analyzes were performed throughout the study period).

  • Analysis of differences in physical activity of people with normal and excessive body weight (obesity).

    All participants completed "International Physical Activity Questionnaire - IPAQ".

    24 months (analyzes were performed throughout the study period).

  • Analysis of differences in quality of life of people with normal and excessive body weight (obesity).

    All participants completed The World Health Organization Quality of Life (WHOQOL- BREF) survey.

    24 months (analyzes were performed throughout the study period).

  • Risk assessment of lower limb atherosclerosis.

    An ankle-brachial index test compares the blood pressure measured at the ankle with the blood pressure measured at the arm was used in the study.

    24 months (analyzes were performed throughout the study period).

STUDY GROUP

Study group included 79 people (48 women and 31 men), with BMI = 30.0-39.9 kg / m2) and excessive total body fat percent (TBF%) content (\>30% TBF women and \>25% TBF men).
