Abstract Background: The aim of this study was to identify the association between obstructive sleep apnea syndrome (OSAS) and abdominal fat distribution in obese individuals.Methods: A total of 94 obese patients were enrolled in the study from January 2018 to July 2020. Demographic data were collected. OSAS was diagnosed based on the results of overnight polysomnography, and the abdominal fat distribution was measured by bioelectrical impedance analysis (BIA). Univariate and multivariate logistic regression analyses were used to investigate the association between OSAS and the distribution of abdominal fat. Results: 1) The mean age (SD) of the patients included in this study was 32.44 (11.81) years and the majority were women (62.77%). The overall incidence rate of OSAS was 51.06%, and 24 (25.53%) patients had mild OSAS, 10 (10.64%) had moderate OSAS, and 14 (14.89%) had severe OSAS. 2) The incidence of OSAS among men was higher than in women (62.86% vs. 44.07%). The apnea hypopnea index (AHI) of men was significantly higher than that of women (5.50, interquartile range [IQR] 3.80-30.6 vs. 4.2, IQR 1.4-12 events/hour, P=0.014). Additionally, men had a significantly higher visceral fat area (180.29±51.64 vs. 143.88±53.42 cm2, P=0.002). 3) Patients with OSAS had a significantly higher visceral fat area than patients without OSAS (178.28±59.89 vs. 135.68±40.58 cm2, P=0.013). Multivariate analysis demonstrated that abdominal fat area and fasting plasma glucose were independent risk factors for OSAS (odds ratio, 1.016; 95% confidence interval, 1.005-1,026, P=0.005; odds ratio, 1.618; 95% confidence interval, 1.149-2.278, P=0.006). Conclusions: In obese patients, the abdominal visceral adipose deposit was an independent risk factor for OSAS. Therefore, improving the distribution of abdominal fat may contribute to alleviating the severity of OSAS.

Abstract ObjectivesSome studies have reported that visceral fat volume measured by computed tomography (CT) was a risk factor for colorectal adenoma (CRA). However, CT is not a good method for risk stratification in clinical use for its radiation. Bioelectrical impedance analysis (BIA) is a non-invasive method for assessment of body composition. The aim of current study was to evaluate the association of body fat measured by BIA with occurrence of CRA.Patients and methods:A total of 410 participants who had underwent screening colonoscopy from Jul 2017 to Dec 2019 in our center were recruited, including 230 with adenoma and 180 without adenoma detected. Body fat of participants were measured by BIA, including body fat mass (BFM), body fat percent (BFP), and waist-to-hip fat ratio. Parameters of metabolic syndrome (MetS) were also measured, including waist circumference, blood pressure, fasting blood glucose, blood level of triglyceride, cholesterol and high-density lipoprotein.ResultsAccording to univariate analysis, age, male proportion, BMI, waist circumference, body fat mass, waist-to-hip fat ratio, blood pressure, and FBG were higher in adenoma group than adenoma-free group, p < 0.05. On multivariate analysis (adjusted for age, sex, smoking, drinking, family history of CRC, etc.), High waist-to-hip fat ratio measured by BIA was associated with occurrence of CRA (compared with normal waist-to-hip fat ratio, OR 1.84; 95% CI, 1.09–3.09; p = 0.02). High waist circumference, as a component of MetS, was also independently associated with CRA (OR 1.90; 95% CI 1.17–3.08, p = 0.01).ConclusionBody fat distribution measured by BIA is associated with occurrence of CRA. Central obesity is a risk factor for CRA.Trial registration: This study was prospectively registered in Chinese Clinical Trials Registry (www.chictr.org.cn; registry number: ChiCTR-RRC-17010862).

AbstractIntroductionProblem of overweight and obesity is more and more common in nowadays. Prevalence of overweight and obesity could have long-range consequences in case of organisation where good health and physical efficiency are requested for personnel to perform their professional roles effectively. Many times soldiers need to maintain very high levels of physical activity to perform their duties and to complete demanding missions, which have a huge physical exertion. Because of that soldiers should stay in an excellent health and stamina.Materials & methodsA total of 355 men soldiers from units with diverse specialisation underwent the examination. The most common criterions to estimate abdominal obesity are waist circumference and waist-to-hip ratio. The evaluation was based on determination of body composition measuring fat tissue percentage and antrophometric indexes: weight, height, waist-to-hip ratio (WHR) and waist circumference (WC). Soldiers were classified to abdominal obesity according to WHR (WHR > 1) and WC (WC > 94). The amount of fat tissue was measured using bioelectrical impedance analysis.ResultsSoldiers were aged 34,56 ± 7,07 years. Median weight and height were respectively 86,04 ± 11,92 kg and 179,14 ± 6,02 cm. 160 soldiers (45%) had a waist circumference higher than 94 cm. The waist-to-hip ratio was higher than 1 for 19% of soldiers. Conducted bioelectrical impedance analysis showed that for 46% of soldiers percentage of fat tissue exceeded 20%.DiscussionThe results showed that the problem of overweight and obesity exists also in military populations. In many cases it is connected with incorrect nutritional behaviours. Soldiers require more proactive approach, because the potentially deleterious health outcomes connected with weight gain may have a negative influence on their work. The biggest effort should be put on a proper nutritional education.

Objectives. The importance of preventive medicine in an aging society is increasing. Locomotive syndrome (LS) is attracting increasing attention. Recently, advances in bioelectrical impedance analysis (BIA) devices have made it possible to automatically measure waist circumference (WC). Nevertheless, there have been no reports evaluating the agreement or interchangeability between WC measured manually and using BIA. Therefore, we aimed to perform these analyses in the context of health checkups and investigated the associations with LS risk. Methods. We enrolled 597 participants who underwent the following: two-step tests and stand-up tests; evaluations using a 25-question geriatric locomotive function scale for the LS risk test; anthropometric marker measurements including WC measured by manual and BIA; and measurements of total cholesterol and triglycerides. We used Bland–Altman analysis to calculate agreement and interchangeability of the WC measurement using BIA and the manual method. A statistical comparative study was then conducted between normal and LS risk groups. Subsequently, significant risk factors for LS were investigated using multivariate analysis. Results. The Bland–Altman analysis showed that bias (BIA-manual) was negative overall (−2.024), for males (−1.418) and for females (−2.460), suggesting underestimation using BIA compared with manual measurements. Interchangeability was found between WC measurement by BIA and by manual methods, because the percentage error was less than 15% overall (12.3%), for males (10.2%) and for females (13.8%). Univariate analysis showed that WC was significantly higher in the LS risk group than in the normal group. Multivariate analysis adjusted for confounding factors showed that increase in WC significantly correlated with LS risk. Conclusions. BIA and manual methods for measuring WC are interchangeable. The increase in WC measured by BIA was significantly associated with LS risk. It is important to continue focusing on increased WC and early detection of LS risk.
