Obesity is a chronic health problem. It is one of the biggest factors for type II diabetes and cardiovascular disease. It is also associated with cancer (e.g. colorectal cancer ), osteoarthritis, liver disease, sleep apnea, depression, and other medical conditions that affect mortality and morbidity. [ 22]
Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. [ 1] The World Health Organization (WHO) classifies obesity by body mass index (BMI). BMI is further evaluated in terms of fat distribution via the waist–hip ratio and total ...
The CDC has found that obesity is the single strongest risk factor for severe COVID-19 illness. [51] Complications are either directly caused by obesity or indirectly related through mechanisms sharing a common cause such as a poor diet or a sedentary lifestyle. The strength of the link between obesity and specific conditions varies.
Since body fat can be measured in several ways, statistics on the epidemiology of obesity vary between sources. While BMI is the most basic and commonly used indicator of obesity, other measures include waist circumference, waist-to-hip ratio, skinfold thicknesses, and bioelectrical impedance. [ 11] The rate of obesity increases with age at ...
Body fat-defined obesity was found in 50% of men and 62% of women. While BMI-defined obesity showed high specificity (95% for men and 99% for women), BMI showed poor sensitivity (36% for men and 49% for women). In other words, the BMI will be mostly correct when determining a person to be obese, but can err quite frequently when determining a ...
Statistics from across the globe demonstrate that approximately 22 million children under the age of five are classified as obese. [8] Some health risks associated with childhood obesity include high blood pressure, high cholesterol levels, insulin resistance and type 2 diabetes. These factors may eventually lead to further complications such ...
