ObesityIs a chronic, recurrent, and progressive disease, and is a global public health challenge.Since 1975, the global prevalence of obesity has more than tripled in men and more than doubled in women. In line with the global trend, the prevalence of obesity in China has also been rising rapidly in recent decades. China CDC's Chronic Disease and Risk Factor Surveillance in China（CCDRFS）The project data shows that, during the period from 2004 to 2018, the prevalence of obesity among Chinese adults more than doubled.(Increased from 3.1% to 8.1%)According to this estimate, there were approximately 85 million people with obesity in China in 2018.。
On August 17, the report "Prevalence of Obesity and Related Comorbidities in China: A Cross-Sectional Real-World Study of 15.8 Million Adults" was published in the academic journal Diabetes, Obesity and Metabolism (IF: 5.8), creating a digital "obesity map of China" based on BMI criteria for overweight and obesity in China.(Body Mass Index)Classification criteria, among 15.8 million adult subjectsThe proportion of overweight people is 34.8%.，The proportion of obese people is 14.1%.。
These data come from 519 Meinian Onehealth Healthcare centers across 243 cities in China. Eligible participants were aged ≥18 years and underwent routine health check-ups in 2019.（N=21771683）, and complete the statistics on height, weight, gender, and region.
01｜Focus on "Big Belly", 41.1% of Men in China Overweight, Obesity Peaks at Ages 35-39
The report data shows that, from the perspective of the "gender difference" in obesity,Overweight and obesity are more common in men than in women., The proportion of overweight men is 41.1%, and women is 27.7%. The proportion of obese men is 18.2%, and women is 9.4%.
"Men are more prone to obesity due to several factors, often related to the stress and emotions they experience in life or work."First, long-term excessive stress and negative emotions can easily lead to endocrine hormone secretion disorders., mainly stress hormone - adrenal glucocorticoid(Commonly referred to by the public as hormones)Increased secretion plays a role in countering insulin, increasing abdominal fat accumulation, and causing abdominal obesity characterized by a "pot belly."
Secondly, to alleviate stress and release emotions, men often resort to unhealthy lifestyle habits such as excessive drinking and overeating.In addition to excessive eating, alcohol often generates a large amount of calories, which also contributes to the formation of obesity.
3. Sleep problems."Long-term sleep deprivation or irregular sleep can also lead to male obesity by disrupting energy balance," Professor Wu Xueyan from the Endocrinology Department of Peking Union Medical College Hospital told the Health Client of the People's Daily.
Moreover, from the "age difference" in obesity, the proportions of overweight and obesity vary between men and women across different age groups. Men typically reach their "peak obesity age" earlier than women. The prevalence of overweight in men peaks between the ages of 50 and 54.(No change for ages 55 to 59), while women reach their peak between the ages of 65 and 69;The prevalence of obesity in men peaks at ages 35-39., andFor women, it is 70-74 years old.。

02｜Prediabetes, Fatty Liver: Nearly 90% of Obese Patients Have Complications
In the general population, the most common obesity-related complications areFatty Liver（34.9%）、Prediabetes（27.6%）、Dyslipidemia（24.9%）AndHypertension（17.6%）Compared with participants of healthy weight, overweight/obese participants had a significantly higher prevalence of complications.(Trend P<0.001)。

"Due to irregular diets and sedentary lifestyles, there has been a dramatic increase in the number of people with metabolic syndrome, characterized primarily by abdominal obesity. Metabolic syndrome is a key predictor of type 2 diabetes and also a high-risk factor for cardiovascular and cerebrovascular diseases. Vascular dysfunction occurs early in metabolic syndrome, and as the disease progresses, macrovascular and microvascular complications will subsequently appear," Li Buman, Deputy Chief of the Endocrinology and Immunology Department at Tsinghua University Yuquan Hospital, told reporters from the People's Daily Health Client.
Professor Wu Xueyan analyzed to the reporter that, in fact, obesity can easily lead to insulin resistance. In the process of human energy metabolism, we need insulin to help transport blood glucose into cell mitochondria to produce energy. If insulin resistance occurs, it will prevent blood glucose from being utilized by the mitochondria of tissue cells, and instead, it gets stored in adipose tissue as fat, which exacerbates obesity and insulin resistance, thus forming a vicious cycle. Therefore, obesity is one of the main factors leading to diabetes.
"Many obese patients exhibit a noticeable early symptom: the appearance of 'acanthosis nigricans' on the neck. 'Acanthosis nigricans' is a characteristic clinical manifestation caused by hyperinsulinemia, serving as a serious warning sign indicating the approach of diabetes. Therefore, obese patients with abnormally high insulin levels should seek medical attention promptly. Doctors may recommend lifestyle changes or even prescribe medications that enhance insulin sensitivity, such as metformin, to reduce insulin levels in the blood and thereby delay or even prevent the onset of diabetes."
Li Buman believes that the important strategy to prevent obesity complications is early detection, early assessment, and early intervention. Metabolic syndrome is a lifestyle disease; controlling diet and increasing exercise are key.Traditional Chinese MedicineComprehensive drug intervention and regulation are necessary measures.
03｜The Most Severe Outbreak of Obesity in Children and Adolescents
According to the "Report on Childhood Obesity in China" released in 2018, the overweight and obesity rate among children and adolescents in China has been rising since the 1990s. In an analysis written by the report's author, Ma Guansheng, Chair of the Department of Nutrition and Food Hygiene at Peking University School of Public Health, along with his colleague Dr. Zhang Na, they noted: "Compared with 1985, the overweight rate among school-age children over 7 years old increased from 2.1% to 12.2% in 2014, while the obesity rate rose from 0.5% to 7.3%. Correspondingly, the number of overweight and obese individuals grew from 6.15 million to 34.96 million."
The aforementioned report mentioned:The prevalence of overweight and obesity among children and adolescents is currently in a rapid upward trend, with the extent of childhood obesity in some large cities approaching levels seen in developed countries.
A nationwide report pointed out: The prevalence of childhood obesity in some large cities has approached or even exceeded the levels of developed countries; a survey targeting some elementary school students in Shanghai showed that the rates of overweight and obesity among first-grade children have surpassed the average levels of American children.
"When faced with a survey on obesity among children in rural China, a spokesperson for the European Society of Cardiology's cardiovascular prevention panel exclaimed: 'This is the worst outbreak of childhood and adolescent obesity I have ever seen... It is very concerning.'"
In fact, according to a 2014 survey conducted by the Joint Research Center for Social Development of East China Normal University and New York University Shanghai, which targeted 73 first-grade students in Shanghai, "the rates of overweight and obesity among the surveyed first-grade children were 46% and 24%, respectively, exceeding the average levels of American children."
According to the "Report on Childhood Obesity in China," the characteristics of the prevalence of childhood obesity in China include: both overweight and obesity rates are on the rise, with the overweight rate being higher than the obesity rate; the rates of overweight and obesity are higher in boys than in girls, and higher in urban areas than in rural areas; in recent years, the rate of obesity among rural children has been increasing rapidly.
"And considering the huge obese population and the proportion of childhood obesity, at the recently concluded 2nd China Obesity Conference, Zhang Zhongtao, Vice President of Friendship Hospital affiliated with Capital Medical University, mentioned: 'By 2030, it is estimated that health expenditures related to overweight and obesity in China will account for approximately 22% of the total national medical costs.'"
