To determine the prevalence of high weight at different characteristics, understand the perceptions and behaviours towards high body weight, and determine potential influencing factors of body weight misperception among high-weight adults in Jilin Province.
A cross-sectional survey with complex sampling design was conducted. We described the prevalence and perception of high body weight.
Northeast China in 2012.
Adults (n 20 552) aged 18-79 years.
Of overweight individuals, 37·4 % considered themselves as 'normal weight', 4·8 % reported themselves as being 'very thin' and only 53·1 % were aware of their own weight being 'overweight'. About 1·8 % of both male and female obese individuals perceived themselves as 'very thin'. Only 29·1 % of obese people thought of themselves as 'too fat'. Nearly 30·0 % of centrally obese men and women perceived that their waist circumference was about right and they were of 'normal weight'; 5·7 % of the centrally obese even perceived themselves as being 'very thin'. Only 51·8 and 12·5 % of centrally obese individuals reported themselves to be 'overweight' or 'too fat'. Body weight misperception was more common in rural residents (OR; 95 % CI: 1·340; 1·191, 1·509). The prevalence of body weight misperception increased with age (middle age: 1·826; 1·605, 2·078; old people: 3·101; 2·648, 3·632) and declined with increased education level (junior middle school: 0·628; 0·545, 0·723; senior middle school: 0·498; 0·426, 0·583; undergraduate and above: 0·395; 0·320, 0·487).
Body weight misperception was common among adults from Jilin Province.
确定不同特征下高体重的患病率，了解对高体重的认知和行为，并确定吉林省高体重成年人中体重误判的潜在影响因素。
采用复杂抽样设计进行横断面调查。我们描述了高体重的患病率和认知情况。
2012年的中国东北地区。
18 - 79岁的成年人（n = 20552）。
超重者中，37.4%认为自己“体重正常”，4.8%称自己“非常瘦”，只有53.1%意识到自己“超重”。约1.8%的男性和女性肥胖者认为自己“非常瘦”。只有29.1%的肥胖者认为自己“太胖”。近30.0%的中心性肥胖男性和女性认为自己的腰围合适且“体重正常”；5.7%的中心性肥胖者甚至认为自己“非常瘦”。只有51.8%和12.5%的中心性肥胖者称自己“超重”或“太胖”。体重误判在农村居民中更为常见（比值比；95%置信区间：1.340；1.191，1.509）。体重误判的患病率随年龄增加而上升（中年：1.826；1.605，2.078；老年人：3.101；2.648，3.632），并随教育水平提高而下降（初中：0.628；0.545，0.723；高中：0.498；0.426，0.583；本科及以上：0.395；0.320，0.487）。
体重误判在吉林省成年人中很常见。
