AbstractAcute mountain sickness (AMS) can occur upon rapid ascent from low to high altitude. This study examined the association between central adiposity and the development of AMS in young adults during a high-altitude hike. Total and regional body fat were measured at sea level using dual-energy X-ray absorptiometry. Within 24 h of arriving in Cusco, Peru (3 400 meters) participants embarked on a 14-mile hike across the Andes Mountain range in southern Peru. Symptoms of AMS were assessed using the Lake Louise score at 24 h (3 400 meters), 29 h (4 100 meters), 34 h (3 800 meters) and 53 h (2 900 meters). 14 participants (mean age 21±2 years; women: 11, men: 3) completed the study. The number of participants exhibiting at least mild AMS increased from 6 (54%) at 3 400 meters to 9 (64%) at 3 800 meters. A higher AMS score at 4 100 meters was associated with greater android (r=0.72, p<0.01), trunk (r=0.73, p<0.01) and total body (r=0.71, p<0.01) fat, but not with total body fat % (r=0.39, p=0.16). Our findings suggest that central obesity, but not total body fat per se, may be an important factor in the development of AMS.

AbstractBackground:The aim of the study was to assess possible relationships between adipocyte fatty acid-binding protein (FABP4) and total body fat (TBF), abdominal fat, body fat distribution, aerobic fitness, blood pressure, cardiac dimensions and the increase in body fat over 2 years in a community sample of children.Methods:A cross-sectional study was used in a community sample of 170 (92 boys and 78 girls) children aged 8–11 years. TBF and abdominal fat (AFM) were measured by dual-energy X-ray absorptiometry (DXA). TBF was also expressed as percentage of total body mass (BF%), and body fat distribution was calculated as AFM/TBF. Maximal oxygen uptake (VOResults:Partial correlations, with adjustment for sex, between FABP4 vs. ln TBF, ln BF%, ln AFM, AFM/TBF and VOConclusions:Findings from this community-based cohort of young children show that increased body fat and abdominal fat, more abdominal body fat distribution, low fitness, more LVM and increased LA, increased SBP and PP were all associated with increased levels of FABP4. Increase in TBF and abdominal fat over 2 years were also associated with increased levels of FABP4.

Abstract Introduction Contradictory reports are available on the role of adipose tissue in the pathophysiology and progression of coronary artery disease (CAD). It seems accepted that local fat distribution is more relevant than the general amount of body fat. As in the case of visceral fat, pericardial adipose tissue (PEAT) has been postulated an important mediator of metabolic risk, with a special role attributed to epicardial adipose tissue (EAT). Purpose To study the effect of intensive dietary and lifestyle modification on the distribution of body fat in patients diagnosed with stable CAD qualified to conservative treatment. Methods Total body fat mass (TBF), visceral fat area (VFA), PEAT volume, and EAT volume were measured in 67 participants (43% women) of the DISCO-CT trial (Dietary Intervention to Stop COronary Atherosclerosis in Computed Tomography, NCT02571803) who completed the study by the end of 2018. All patients, randomly assigned to either experimental or control arm in a 1:1 fashion, were regularly followed-up at our site, with those in the experimental arm being strictly supervised by a dietitian to stick to Dietary Approaches to Stop Hypertension (DASH) diet and encouraged to lifestyle changes atop optimal medical therapy. Contrast-enhanced coronary computed tomography was performed at baseline and after the median time of 59 weeks (2x192-multislice scanner, temporal resolution 66 ms, Somatom Force, Siemens). PEAT and EAT volumes, expressed in mm3, were measured with a dedicated offline workstation (syngo.via Frontier, Siemens Healthcare) using a semiautomatic segmentation technique (window width range −195 to −45 Hounsfield units). TBF, expressed in kg, and VFA, expressed in cm2, were measured using the InBody S10 Body Water Analyser at baseline and completion of the study. 57% of subjects included into the analysis represented the experimental arm. Results There were no significant between-arm differences in baseline TBF, VFA, PEAT, and EAT volumes. A significant reduction by 3.7±5.0 kg in TBF (p<0.001; 95% CI 2.1, 5.3) and by 19.7±30.1 cm2 in VFA (p<0.001; 95% CI 9.8, 29.6) was observed in the experimental arm, while in the control group both TBF and VFA irrelevantly increased, by 0.6±4.7 kg (p=0.53; 95% CI −2.4, 1.3) and 2.2±27.0 cm2 (p=0.67; 95% CI −12.7, 8.2), respectively. A significant decrease in PEAT volume, by 19.9±43.0 mm3 (p=0.007; 95% CI 5.8, 34.1), was observed in the experimental group, compared to a non-significant PEAT volume reduction by 5.8±3.5.0 mm3 (p=0.38, 95% CI −7.5; 19.2) in the control group. Contrarily, no significant changes in EAT volumes were observed in either experimental (reduction by 3.8±15.2 mm3; p=0.13, 95% CI −1.2, 8.8) or control arm (reduction by 5.1±17.2 mm3; p=0.13, 95% CI −1.5, 11.6). Conclusion Intensive dietary intervention in patients with stable CAD can lead to a significant reduction in total body fat, visceral fat and pericardial fat, this effect, however, may not apply to epicardial fat.

Background: Body mass index (BMI) is commonly used as a proxy to determine excess adiposity, though this may underestimate fat mass (FM) in individuals of South Asian (SA) heritage. SA tend to have greater central adiposity than white people, which is associated with a higher risk of cardiometabolic disease. In this cross-sectional study, we aimed to determine the differences in total and regional FM using Dual-energy X-ray absorptiometry (DXA), and to see if any differences in FM varied by BMI category in UK-born white and SA children aged ~9 years. Methods: Anthropometric measurements and DXA scans were undertaken from 225 white and 269 SA children from the Born in Bradford cohort study. Linear regression was used to assess ethnic differences in total body fat percent and total and regional FM. Results: Although the mean BMI was similar, compared to white children, the proportion of SA children who were overweight or obese was ~20% higher, they had a median of 2kg more total FM, and the proportion with > 35% total body fat (TBF) was 22% and 16% higher in boys and girls respectively. Mean TBF% was greater in each BMI category, as was truncal, android and gynoid FM, with the greatest differences between ethnic groups observed in the healthy and overweight categories. Conclusions: Greater TBF% and total and regional FM in the healthy- and overweight BMI categories observed in SA children suggests they may be at greater risk of future cardiometabolic disease at a BMI level below obesity threshold. However, our sample size was small, and results may be influenced by selection bias and confounding; our findings need to be replicated in a larger study.
