BMI is a useful inexpensive tool to categorize people and is highly correlative with disease risk, but other measurements are needed to diagnose obesity and more accurately assess disease risk.

Introduction Obesity is becoming more widespread all over the world, according to Global Burden of Disease Group research 1.

Fat mass distribution -

We reclassified the patients according to their comorbidity types, mainly including CCVD, MD, RD, liver disease, renal disease, cancer, and joint disease, and studied the relationship between fat distribution and different types of comorbidities. Similarly, the quintiles OR value of Gynoid fat ratio and subcutaneous fat ratio, and CCVD comorbidity risk showed a decreasing trend, indicating that its protective effect was gradually increasing Figure S5.

However, when fat distribution was associated with the risk of RD, liver disease, renal disease, cancer, and joint disease, these relationships were less regular Figures S7—S In addition, we also conducted some sensitivity analyses and discovered that the results were stable.

To overcome the bias caused by age grouping, we reset the age boundary and investigated the role of fat distribution in obese participants at the age of Android fat ratio OR, 2. Conversely, the risk effect of Android fat ratio OR, 5. In women, the results were similar Figure S Considering the impact of menstrual status on female fat distribution and some disease risks CCVD , the results of subgroups of people with menstrual status by age showed that the comorbidity risk of postmenopausal older participants seemed more likely to be affected by abnormal fat distribution Figure S In addition, in order to avoid the impact of estrogen use, we made additional adjustments to the estrogen use of participants with complete estrogen use information, and the results were still stable Table S5.

We analyzed 60 million obese individuals aged 20—59 years in this large-scale prospective study that can represent the majority of the US population. The results showed that even the central regional fat was highly heterogeneous, with different fat distributions having distinct consequences on comorbidity risk.

The Gynoid fat ratio accumulation provided protection. Furthermore, in men, the accumulation of abdominal subcutaneous fat performed a protective role in the risk of comorbidity.

However, the change in total abdominal fat had no discernable effect on the incidence of comorbidity. Further subgroup analysis showed that the effects of fat distribution were more strongly correlated with comorbidity risk in older participants, as well as complex comorbidity, CCVD, and MD.

This study initially investigated the differences in fat distribution among obese participants of different sexes and ages. Second, this difference was mirrored in fat function. We also discovered that in men, both visceral fat ratio and subcutaneous fat ratio were strongly linked with comorbidity risk, but in women, only visceral fat ratio was significantly associated with comorbidity risk.

This result was completely consistent with the results of Mutsert et al. As a result, in women, just variations in visceral fat may need to be assessed for stratification of comorbidity risk, but in men, the potential effects of subcutaneous fat may need to be additionally assessed. Second, age was an important reason for the differences in fat distribution among participants.

With advancing age, Android fat, visceral fat, and abdominal fat increased, but Gynoid fat and subcutaneous fat decreased.

This also coincided with previous research results. Aging promotes fat redistribution, that is, loss of subcutaneous fat and growth of visceral fat, and hormonal imbalance can also invert the distribution of Android and Gynoid fat In terms of fat function, older participants were more susceptible to fat than younger participants, which was consistent with previous studies.

Preis et al. also found a stronger correlation between fat distribution and metabolic diseases in older participants For obese participants, complex comorbidities are a difficult public health prevention target Although some studies have noted the relationship between fat distribution or obesity degree and various comorbidities, for example, a recent study by Mika et al.

However, few studies have elucidated the relationship between fat distribution and complex comorbidity. When compared to people with simple comorbidity, the fat distribution of participants with complex comorbidity was more closely related to comorbidity risk, and this trend was not affected by sex.

The results of this study were unprecedented because it effectively filled the deficiency in previous studies that relied solely on BMI to determine the risk of complex comorbidity. A large number of studies have shown a strong correlation between obesity and various types of comorbidities, with the most widely reported comorbidities being cardiovascular, metabolic, and respiratory diseases 29 — Albert et al.

showed that obesity can cause a variety of hemodynamic changes, which may lead to cardiac morphological changes and ventricular dysfunction Although this theory has been widely confirmed, we cannot ignore the latest research on the obesity paradox in cardiovascular disease.

The mortality of patients with any kind of heart failure has decreased as BMI has increased This contradictory phenomenon prompts us to focus our research on body composition.

However, the Gynoid fat ratio and subcutaneous fat ratio played considerable protective roles. The increase in BMI will not benefit all obese people. Participants will not benefit from a rise in BMI induced by Android and visceral fat.

Similarly, while obesity is associated with the occurrence of MD such as diabetes and gout 34 , 35 , the risk of MD caused by fat in different regions was not the same. The most reasonable explanation for this phenomenon is fat heterogeneity. The Android fat and visceral fat are composed of white adipose tissues WAT , which contribute to metabolism and chronic inflammation in vivo , while triglycerides accumulation in WAT cells in obese people triggers WAT cells remodeling, proliferation, and hypertrophy.

The ERK and p38 MAPK pathways are activated by adipocytokines secretion, resulting in increased CCL2 expression in adipocytes. This in turn triggers pro-inflammatory macrophage aggregation, Treg cell reduction, and IL-6 and TNF-α secretion increases, leading to systemic inflammation, insulin resistance, oxidative stress, and a series of metabolic reactions 36 , As for Gynoid fat, estrogen induction increases the anti-lipolytic α2-adrenergic receptors in the gluteal-femoral subcutaneous fat depot, causing fat to accumulate in the Gynoid area; hence, Gynoid fat distribution is closely related to estrogen levels Estrogen has been widely recognized as an important factor in regulating obesity and metabolic balance in the body Alternatively, by activating eNOS and increasing NO production, as well as activating cardioprotective signaling cascades including Akt and MAP kinases, cardiac and endothelial cells are protected against apoptosis and necrosis, alleviating pathological myocardial hypertrophy Estrogen also plays an important role in metabolic pathways.

Animal experiments have shown that estrogen can increase insulin content and glucose-stimulated insulin secretion in isolated mouse islets, and maintain glucose homeostasis, while its deficiency will disturb oxidative stress and endoplasmic reticulum function, resulting in a complete disorder of insulin function and in vivo metabolism.

Therefore, the accumulation of Gynoid fat caused by increased estrogen significantly reduces the risk of comorbidity in obese people. Interestingly, the increase in total abdominal fat did not appear to affect the risk of any type of comorbidity in this study, which differs slightly from previous reports indicating total abdominal fat was an independent risk factor for cardiovascular disease Visceral fat is primarily responsible for the risk of total abdominal fat, while subcutaneous fat has a protective effect.

This is the first study to systematically study the fat distribution and comorbidity risk, complex comorbidity, and comorbidity types of obese people aged 20—59 years.

Second, the part of our study on complex comorbidities is of great public health significance. Notwithstanding, our study also had some limitations. Finally, changes in menstrual status, hormone treatment and hormone level may affect the distribution and mass of fat, thus affecting the results.

However, due to the limitations of NHANES database, we did not adjust these covariants. In future clinical research, we will pay more attention to these aspects. Taken together, these results have clinical and public health implications, and our study highlights the correlation between fat distribution and comorbidity, which is influenced by sex, age, number of comorbidities, and type of comorbidity.

As we age, we should pay more attention to changes in central fat distribution, and people with abnormal fat distribution should be on the lookout for CCVD and MD. Furthermore, because of the strong correlation between abnormal fat distribution and complex comorbidities, it is particularly important to distinguish the fat function of various parts of obese people.

This result provides clinical guidance that obesity treatment such as life intervention, pharmacotherapy and bariatric surgery should be used with greater caution and precision for young and middle-aged obese people. Further inquiries can be directed to the corresponding author.

It is inexpensive and convenient, but accuracy depends on the skill and training of the measurer. At least three measurements are needed from different body parts. The calipers have a limited range and therefore may not accurately measure persons with obesity or those whose skinfold thickness exceeds the width of the caliper.

BIA equipment sends a small, imperceptible, safe electric current through the body, measuring the resistance. The current faces more resistance passing through body fat than it does passing through lean body mass and water. Equations are used to estimate body fat percentage and fat-free mass.

Readings may also not be as accurate in individuals with a BMI of 35 or higher. Individuals are weighed on dry land and then again while submerged in a water tank.

This method is accurate but costly and typically only used in a research setting. It can cause discomfort as individuals must completely submerge under water including the head, and then exhale completely before obtaining the reading. This method uses a similar principle to underwater weighing but can be done in the air instead of in water.

It is expensive but accurate, quick, and comfortable for those who prefer not to be submerged in water. Individuals drink isotope-labeled water and give body fluid samples. Researchers analyze these samples for isotope levels, which are then used to calculate total body water, fat-free body mass, and in turn, body fat mass.

X-ray beams pass through different body tissues at different rates. DEXA uses two low-level X-ray beams to develop estimates of fat-free mass, fat mass, and bone mineral density. It cannot distinguish between subcutaneous and visceral fat, cannot be used in persons sensitive to radiation e.

These two imaging techniques are now considered to be the most accurate methods for measuring tissue, organ, and whole-body fat mass as well as lean muscle mass and bone mass. However, CT and MRI scans are typically used only in research settings because the equipment is extremely expensive and cannot be moved.

CT scans cannot be used with pregnant women or children, due to exposure to ionizing radiation, and certain MRI and CT scanners may not be able to accommodate individuals with a BMI of 35 or higher.

Some studies suggest that the connection between body mass index and premature death follows a U-shaped curve. The problem is that most of these studies included smokers and individuals with early, but undetected, chronic and fatal diseases.

Cigarette smokers as a group weigh less than nonsmokers, in part because smoking deadens the appetite. Potentially deadly chronic diseases such as cancer, emphysema, kidney failure, and heart failure can cause weight loss even before they cause symptoms and have been diagnosed.

Instead, low weight is often the result of illnesses or habits that may be fatal. Many epidemiologic studies confirm that increasing weight is associated with increasing disease risk.

The American Cancer Society fielded two large long-term Cancer Prevention Studies that included more than one million adults who were followed for at least 12 years. Both studies showed a clear pattern of increasing mortality with increasing weight.

According to the current Dietary Guidelines for Americans a body mass index below But some people live long, healthy lives with a low body mass index.

Search for:. Home Nutrition News What Should I Eat? Role of Body Fat We may not appreciate body fat, especially when it accumulates in specific areas like our bellies or thighs. Types of Body Fat Fat tissue comes in white, brown, beige, and even pink.

Types Brown fat — Infants carry the most brown fat, which keeps them warm. It is stimulated by cold temperatures to generate heat.

The amount of brown fat does not change with increased calorie intake, and those who have overweight or obesity tend to carry less brown fat than lean persons. White fat — These large round cells are the most abundant type and are designed for fat storage, accumulating in the belly, thighs, and hips.

They secrete more than 50 types of hormones, enzymes, and growth factors including leptin and adiponectin, which helps the liver and muscles respond better to insulin a blood sugar regulator. But if there are excessive white cells, these hormones are disrupted and can cause the opposite effect of insulin resistance and chronic inflammation.

Beige fat — This type of white fat can be converted to perform similar traits as brown fat, such as being able to generate heat with exposure to cold temperatures or during exercise.

Pink fat — This type of white fat is converted to pink during pregnancy and lactation, producing and secreting breast milk. Essential fat — This type may be made up of brown, white, or beige fat and is vital for the body to function normally.

It is found in most organs, muscles, and the central nervous system including the brain. It helps to regulate hormones like estrogen, insulin, cortisol, and leptin; control body temperature; and assist in the absorption of vitamins and minerals.

Very high amounts of subcutaneous fat can increase the risk of disease, though not as significantly as visceral fat. Having a lot of visceral fat is linked with a higher risk of cardiovascular disease, diabetes, and certain cancers.

It may secrete inflammatory chemicals called cytokines that promote insulin resistance. How do I get rid of belly fat?

Losing weight can help, though people tend to lose weight pretty uniformly throughout the body rather than in one place. However, a long-term commitment to following exercise guidelines along with eating balanced portion-controlled meals can help to reduce dangerous visceral fat.

Also effective is avoiding sugary beverages that are strongly associated with excessive weight gain in children and adults. Bioelectric Impedance BIA BIA equipment sends a small, imperceptible, safe electric current through the body, measuring the resistance.

Underwater Weighing Densitometry or Hydrostatic Weighing Individuals are weighed on dry land and then again while submerged in a water tank.

Air-Displacement Plethysmography This method uses a similar principle to underwater weighing but can be done in the air instead of in water.

Dilution Method Hydrometry Individuals drink isotope-labeled water and give body fluid samples. Dual Energy X-ray Absorptiometry DEXA X-ray beams pass through different body tissues at different rates. Computerized Tomography CT and Magnetic Resonance Imaging MRI These two imaging techniques are now considered to be the most accurate methods for measuring tissue, organ, and whole-body fat mass as well as lean muscle mass and bone mass.

Differences in white adipose tissue WAT lipid turnover between the visceral vWAT and subcutaneous sWAT depots may cause metabolic complications in obesity. Here we compare triglyceride age and, thereby, triglyceride turnover in vWAT and sWAT biopsies from individuals and find that subcutaneous triglyceride age and storage capacity are increased in overweight or obese individuals. Visceral triglyceride age is only increased in excessively obese individuals disttribution associated with a lower lipid removal capacity.

Fat mass distribution -

A subgroup of obese individuals - the 'metabolically healthy obese' MHO - have a better adipose tissue function, less ectopic fat storage, and are more insulin sensitive than obese metabolically unhealthy persons, emphasizing the central role of adipose tissue function in metabolic health.

However, controversy has surrounded the idea that metabolically healthy obesity may be considered really healthy since MHO individuals are at increased cardio metabolic disease risk and may have a lower quality of life than normal weight subjects due to other comorbidities.

Detailed metabolic phenotyping of obese persons will be invaluable in understanding the pathophysiology of metabolic disturbances, and is needed to identify high-risk individuals or subgroups, thereby paving the way for optimization of prevention and treatment strategies to combat cardiometabolic diseases.

Keywords: Adipose tissue function; Body fat; Metabolic health; Obesity; Oxygen. Other methods of measuring fat mass are more expensive and more technically challenging. They include:. Total body-fat mass is one predictor of health; another is how the fat is distributed in the body.

You may have heard that fat on the hips is better than fat in the belly—this is true. Fat can be found in different areas in the body and it does not all act the same, meaning it differs physiologically based on location.

Fat deposited in the abdominal cavity is called visceral fat and it is a better predictor of disease risk than total fat mass. Visceral fat releases hormones and inflammatory factors that contribute to disease risk.

The only tool required for measuring visceral fat is a measuring tape. The measurement of waist circumference is taken just above the belly button.

Men with a waist circumference greater than 40 inches and women with a waist circumference greater than 35 inches are predicted to face greater health risks. The waist-to-hip ratio is often considered a better measurement than waist circumference alone in predicting disease risk. To calculate your waist-to-hip ratio, use a measuring tape to measure your waist circumference and then measure your hip circumference at its widest part.

Next, divide the waist circumference by the hip circumference to arrive at the waist-to-hip ratio. A study published in the November issue of Lancet with more than twenty-seven thousand participants from fifty-two countries concluded that the waist-to-hip ratio is highly correlated with heart attack risk worldwide and is a better predictor of heart attacks than BMI.

Abdominal obesity is defined by the World Health Organization WHO as having a waist-to-hip ratio above 0. Skip to content Although the terms overweight and obese are often used interchangeably and considered as gradations of the same thing, they denote different things.
