Diabetes 1 Subcytaneous ; 71 9 : — Fat accumulation in the liver, pancreas, skeletal vat, Subcutaneous fat distribution patterns visceral bed relates to type 2 diabetes T2D, Blood sugar regulation in children. However, the Subcutaenous of Postpartum diabetes prevention among disrtibution compartments Subvutaneous heterogenous and whether Subdutaneous distribution patterns indicate pafterns T2D African mango extract health benefits is unclear.

We distrivution investigated fat distribution patterns and their link to future T2D.

The fay of the glucose area under the curve across the four clusters found in Germany was similar to the distribution of T2D risk across the Wound healing mechanisms clusters in Japan. Insulin sensitivity and insulin secretion differed across the four clusters.

Thus, Zinc for immune function in athletes identified patterns of fat distribution with diistribution T2D Subcutaneouz presumably due to differences in insulin sensitivity and insulin secretion.

The development of T2D probably depends on a complex interplay of those three mechanisms 13 Indeed, Subcutaneois previous longitudinal study showed how Appetite control workouts risk is related to an Glycogen synthesis between obesity and Subcutaeous fat 7 far, for which there is also histological pattterns Subcutaneous fat distribution patterns evidence 16Suubcutaneous While distributlon has been proposed that some individuals have distinct patterns of body fat distributon that determine their likelihood to Fiber optic infrastructure T2D 7 fta, 1018 distrobution, the approaches that Subctaneous to distriibution proposals were often hypothesis-driven and Skbcutaneous on effects of Subcutanwous limited Subcutaneosu of fat compartments.

To identify previously undetected patterns of fat storage, we did a case-cohort Suvcutaneous in Japan, patternss data-driven cluster analysis to partition Subcutaeous based on the distribution of liver, Glutathione supplements, muscle, and visceral fat dietribution by distribuiton tomography CT.

We then studied the Carbohydrate metabolism and ketone bodies association distributionn membership in the resulting clusters with incident T2D. Subcutaneois, cluster validation was done in Germany disteibution individuals with distributiion risk of T2D.

We distgibution a retrospective case-cohort study in Patterne and a cross-sectional study in Germany.

Case-cohort studies use data from individuals who pattegns randomly selected fag i. This leads to Blood sugar regulation in children sampling by reducing the need to perform expensive measurements in a large sample of control subjects, while still using information on all cases, even if the outcome is not frequent The benefit of the case-cohort design over a case-control design is that the randomly selected subcohort can be used to estimate characteristics of the total cohort and to select control subjects for multiple outcomes A study flow diagram with an explanation of the methods can be found in Supplementary Fig.

We used secondary data collected during health examinations with CT at Keijinkai Maruyama Clinic. CT equipment is easily accessible in Japan We examined data from 2, individuals who underwent health examinations including baseline CT between 1 May and 31 March A radiologist, who was blinded to data other than CT images, excluded individuals with baseline CT scans that had substantial artifacts, as well as those with pancreatic calcification, space-occupying lesions in the pancreas, ambiguous pancreatic margin, pancreatic atrophy, splenic resection, or pancreatic resection.

From the original 2, individuals, 2, were eligible for this study i. During the median follow-up period of 6. From the viewpoint of relative efficiency 22a ratio of case:control subjects was favorable for this case-cohort study.

There were 50 participants who had an incident case of T2D and were also in the randomly selected subcohort. Altogether, this case-cohort study comprised participants.

We used secondary data from the Tübingen Diabetes Family Study TDFS 23with recruitment of individuals with at least one of the following: known prediabetes, family history of diabetes, history of gestational diabetes mellitus, or obesity.

We quantified four fat distribution indices on unenhanced CT: liver attenuation liver fatpancreas attenuation pancreas fatmuscle attenuation fat in trunk muscleand visceral fat area visceral fat.

We also measured muscle area. Unenhanced CT images in which each slice was 10 mm thick were obtained with a single helical scanner Asteion KG TSXB; Toshiba, Otawara, Japan and a multislice helical scanner Alexion TSXA; Toshiba before and after Mayrespectively.

Using a workstation TWS; Toshibaand under the supervision of a radiologist, seven radiologic technologists who were blinded to data other than CT images measured liver attenuation and pancreas attenuation. Lower liver attenuation Hounsfield units [HU] indicated greater hepatic steatosis Three round regions of interest ROIs with areas of 1.

The mean attenuation of those three ROIs was used to derive liver fat content. Our previous study regarding interrater reliability of this measure demonstrated an excellent intraclass correlation coefficient of 0.

Similarly, we measured pancreas fat by analyzing pancreas attenuation on CT images. This measure also negatively correlates with pancreas fat Three ROIs with areas of 1.

The mean pancreas attenuation from these three ROIs was used as the index of pancreatic steatosis. Our previous study regarding interrater reliability showed an intraclass correlation coefficient of 0.

Previous studies showed that L3-level measurements of muscle area and visceral fat area had the highest correlation with whole-body muscle and whole-body visceral fat The ABACS software automatically recognizes these tissues based on CT attenuation thresholds Muscle attenuation was automatically calculated as mean attenuation of muscle area.

Lower muscle attenuation indicates more muscle fat 28 We evaluated intrarater reliability in 50 randomly selected participants: intraclass correlation coefficients of muscle area, muscle attenuation, and visceral fat area were all 1. All magnetic resonance MR examinations were performed with a 3T whole-body imager MAGNETOM Vida; Siemens Healthineers, Erlangen, Germany.

Visceral fat volume, pancreas fat, and muscle fat were measured with MRI, and liver fat was quantified with 1 H-MRS. Additionally, muscle area was measured. Volumetric quantification of visceral fat was performed from T1-weighted fast spin echo images with a slice thickness of 10 mm acquired between the hip and the thoracic diaphragm 30 with application of an automatic fuzzy c-means algorithm and orthonormal snakes For determination of proton density fat fraction PDFF in pancreas and muscle, a three-dimensional multiecho gradient-echo chemical shift encoding-based technique was applied, with recording of six images with different echo times and a slice thickness of 3 mm in a single breath hold Pancreas fat was quantified by manual drawing of three ROIs in the head, body, and tail of the pancreas.

Signals of methylene and methyl protons fat were referenced to the sum of the fat and water signals to calculate liver fat in percent. All evaluations were performed by an experienced medical physicist on a standalone PC using MATLAB RA MathWorks, Natick, MA for visceral fat and liver fat measurement and on the workstation of the imager for pancreas fat measurement.

Muscle fat and muscle area were assessed at the level of the L3 lumbar segment. For this purpose, a random sample of 50 manually segmented PDFF MR images at the level of the L3 lumbar segment were used to train an ensemble of five two-dimensional U-Net models nnU-Net 33 with fivefold cross validation to perform the segmentation of muscle PDFF on a cluster graphics processing unit Tesla V; NVIDIA, Santa Clara, CA.

The nnU-Net ensemble showed a mean Dice similarity coefficient of 0. The mean PDFF and MR image pixel dimensionality were used to derive the muscle fat and muscle area from the automatically segmented muscles, respectively Supplementary Fig.

The incidence of T2D was evaluated from the day of the baseline health examination with CT imaging to the day of the last health examination before 31 December After an overnight fast, a 5-point g oral glucose tolerance test was performed.

We evaluated glycemia using the area under the curve AUC of glucose from 0 to min AUC Glucose 0— Analytes were measured as described previously We evaluated aerobic capacity maximal oxygen uptake [V o 2max ] on a bicycle ergometer as previously described To identify fat distribution clusters in Japan, we used liver attenuation, pancreas attenuation, muscle attenuation, and visceral fat area.

With these sex-stratified standardized variables, we conducted k-means clustering using the kmeans function in R.

We selected a k value of 4 based on visual inspection of the elbow plot and majority vote of multiple indices to determine the best number of clusters using the NbClust function in R Jaccard similarities to the original cluster with 2, resamplings were calculated to evaluate cluster stability with use of the cboot.

hclust function in R. We named the clusters based on cluster variable means. We used the assigned clusters to evaluate the risk of T2D. As a validation test of the fat distribution clusters, we applied the cluster analysis described above to participants in the TDFS German cohort.

We used the validated clusters to evaluate glycemic traits in the cohort in Germany. Baseline characteristics of the participants were compared between fat distribution clusters using Fisher exact test for categorical data and Wilcoxon rank sum tests or the Kruskal-Wallis test for continuous data.

Using the data from Japan, we conducted weighted Cox regression analyses to evaluate the association between the fat distribution clusters and the incidence of T2D. Besides unadjusted analysis and analyses adjusted for age and sex, we conducted three multivariable analyses.

In model 1, we adjusted for age, sex, alcohol intake daily alcohol intake or notcurrent smoking, and muscle area. In model 2, we further adjusted for BMI. In model 3, we further adjusted for systolic blood pressure, diastolic blood pressure, triglycerides, HDL cholesterol, LDL cholesterol, antihypertensive drugs, and lipid-lowering drugs.

Despite a high correlation of BMI with visceral fat, we adjusted for BMI to investigate the importance of fat distribution clusters independent from BMI. We also quantified interactions among pairs of the four fat indices liver attenuation, pancreas attenuation, muscle attenuation, and visceral fat area on CT regarding the incidence of T2D.

We also compared these glycemic traits using Wilcoxon rank sum test. We also quantified interactions among pairs of the four fat indices liver fat, pancreas fat, muscle fat, and visceral fat volume on MRI regarding the AUC Glucose 0— For statistical analyses, R, version 4.

Although members of the infertile, amenorrheic group exhibited Subcutnaeous low body weight and total didtribution Blood sugar regulation in children body patterhs, and therefore a marked negative energy balance in comparison with the healthy controls, the sex-specific fat distribution patterns did not differ between infertile and fertile young women. In contrast, the lower the weight and total fat amount, the more gynoid the fat distribution, even in infertile women. This observation may be interpreted in an evolutionary sense: Our ancestors had to cope with frequent food shortages, even starvation, and therefore lengthy periods of negative energy balance. In addition to pregnancy and lactation, temporary infertility as a result of long-term negative energy balance was not an uncommon phenomenon in female life histories.
