The purpose of the present study was to evaluate the association between self-perception of body weight, weight loss approaches and measured body mass index (BMI) and waist circumference (WC) among Sri Lankan adults.
A nationally representative sample of 600 adults aged ≥18 years was selected using a multi-stage random cluster sampling technique. An interviewer-administrated questionnaire was used to assess demographic characteristics, body weight perception, abdominal obesity perception and details of weight losing practices. Weight, height and waist circumference (WC) were measured and Asian anthropometric cut-offs for BMI and WC were applied.
Body weight mis-perception was common among Sri Lankan adults. Two-thirds of overweight males and 44.7% females considered themselves as ‘about right weight’, moreover, 4.1% and 7.6% overweight men and women reported themselves as being ‘underweight’. Over one third of both male and female obese subjects perceived themselves as ‘about right weight’ or ‘underweight’. Nearly 32% of centrally obese men and women perceived that their WC is about right. People who perceived themselves as overweight or very overweight (n = 154) only 63.6% tried to lose weight (n = 98), and one quarter of adults sought advice from professionals (n = 39).
Body weight misperception was common among underweight, healthy weight, overweight, and obese adults in Sri Lanka. Over 2/3 of overweight and 1/3 of obese Sri Lankan adults believe they are in right weight category or are under weight.
本研究旨在评估斯里兰卡成年人的体重自我认知、减肥方法与测量的体重指数（BMI）和腰围（WC）之间的关联。
采用多阶段随机整群抽样技术，选取了600名年龄≥18岁的具有全国代表性的成年人样本。使用由访员管理的问卷来评估人口统计学特征、体重认知、腹部肥胖认知和减肥做法的细节。测量体重、身高和腰围（WC），并应用亚洲BMI和WC的人体测量临界值。
体重误判在斯里兰卡成年人中很常见。三分之二的超重男性和44.7%的超重女性认为自己“体重合适”，此外，4.1%的超重男性和7.6%的超重女性称自己“体重过轻”。超过三分之一的肥胖男性和女性认为自己“体重合适”或“体重过轻”。近32%的中心性肥胖男性和女性认为自己的腰围合适。自认为超重或非常超重的人（n = 154）中只有63.6%试图减肥（n = 98），四分之一的成年人向专业人士寻求建议（n = 39）。
在斯里兰卡，体重误判在体重过轻、健康体重、超重和肥胖的成年人中都很常见。超过三分之二的超重和三分之一的肥胖斯里兰卡成年人认为自己体重正常或体重过轻。
