按性别划分，男性超重患病率在50-54岁达到峰值，在55-59岁保持，而女性在65-69岁达到峰值。男性的肥胖患病率在35-39岁达到峰值，而女性在70-74岁达到峰值。

The prevalence of overweight peaked at age 50 to 54 in males and at age 65 to 69 in females. The prevalence of obesity peaked at age 35 to 39 in males and at age 70 to 74 in females.

北京协和医院内分泌科教授伍学焱表示，男性更容易患肥胖的原因有多种，通常与生活或工作中的压力和情绪有关。

There are several reasons why men are more prone to obesity, with causes usually related to the stress and emotions in life or work, said Wu Xueyan, a professor from the endocrinology department at Peking Union Medical College Hospital.

伍教授解释，长期过度的压力和负面情绪可能导致应激激素——肾上腺糖皮质激素的分泌增加，这些激素会对抗胰岛素并增加腹部脂肪积累。

Long-term excessive stress and negative emotions could lead to the increased secretion of stress hormone — adrenal glucocorticoid, which plays a role in combating insulin and increasing abdominal fat accumulation, according to Wu.

为了减轻压力和释放情绪，男性常常采用不健康的生活方式，如饮酒和暴饮暴食，而长期的睡眠不足或不规律也可能导致男性肥胖。

In order to relieve stress and release emotions, men often resort to unhealthy lifestyles such as drinking alcohol and overeating, and long term insufficient or irregular sleep can also lead to male obesity, Wu said.

就地区而言，北方超重/肥胖的比例普遍高于南方，其中超重比例前三名的省份为内蒙古（37.1%）、山东（37.1%）和河北（36.6%）。

By region, the proportion of overweight and obesity in the north is generally higher than that in the south, with Inner Mongolia (37.1 percent), Shandong (37.1 percent), and Hebei (36.6 percent) ranking among the top three.

Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms and height in metres.

Due to poor diet and sedentary behavior, the population with metabolic syndrome, characterized by abdominal obesity, has increased significantly in modern times, said Li Buman, deputy director of endocrine immunology department at Tsinghua University Yuquan Hospital.
