To determine the prevalence of body image accuracy/distortion in Brazilian men and women and to investigate sociodemographic and lifestyle-related factors, and the presence of chronic diseases associated with body image distortion.
Data from 6,357 men and 7,657 women participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were collected using a multidimensional questionnaire covering sociodemographic characteristics, health behaviors, heath conditions and body image perception.
Most participants (53.5% of the women and 54.7% of the men) were found to have an accurate self-perception of their body. When the factors associated with the perception of being heavier than reality were investigated, adopting weight loss measures and not being hypertensive proved protective against this distortion, both in women and men. Conversely, the perception of being lighter than reality was associated, in both women and men, with better education, being black or of mixed race, adopting weight loss measures and not being hypertensive or diabetic. Additional factors associated with underestimating weight were not consuming alcohol (only in women) and belonging to a lower social class (only in men).
These findings may contribute to the implementation of public health policies and interventions to promote health and well-being in the Brazilian population.
确定巴西男性和女性身体形象准确/扭曲的患病率，并调查社会人口学和生活方式相关因素，以及与身体形象扭曲相关的慢性病的存在情况。
使用涵盖社会人口学特征、健康行为、健康状况和身体形象认知的多维问卷，收集了参与巴西成人健康纵向研究（ELSA - Brasil）的6357名男性和7657名女性的数据。
发现大多数参与者（53.5%的女性和54.7%的男性）对自己的身体有准确的自我认知。在调查与感觉比实际体重更重的认知相关的因素时，采取减肥措施且未患高血压对女性和男性的这种扭曲都有保护作用。相反，感觉比实际体重更轻的认知在女性和男性中都与受教育程度更高、为黑人或混血、采取减肥措施以及未患高血压或糖尿病有关。与低估体重相关的其他因素在女性中是不饮酒，在男性中是属于较低社会阶层。
这些发现可能有助于实施公共卫生政策和干预措施，以促进巴西人口的健康和福祉。
