While numerous studies have investigated body image, including body weight perception,most of which have focused on adolescents or young women, few studies have attempted toevaluate body weight perceptions in adult women according to age groups. This study wasconducted to investigate the accuracy of self-perceived weight and actual body mass index(BMI) values among adult Korean women according to age. We used data from the 2016Korean Study of Women’s Health Related Issues, a population-based, nationwide, crosssectionalsurvey. BMI was calculated from self-reported weight and height. Participants wereasked to describe their body image by choosing one of the following deions: veryunderweight, underweight, about right, overweight, or obese. The proportions of womenaged 20–29, 30–39, 40–49, 50–59, 60–69, and 70–79 years who underestimated their bodyweight relative to their actual BMI category were 12.6%, 15.1%, 22.2%, 34.0%, 45.6%, and50.7%, respectively; those who overestimated their body weight comprised 18.7%, 17.8%,14.3%, 10.8%, and 7.4%. In all BMI categories, the proportion of those who overestimatedtheir weight status increased as age decreased, while those who underestimated theirweight status increased as age increased. After adjusting for possible covariates, age wasstrongly associated with both underestimation and overestimation. The odds ratio for underestimatingone’s weight status among women aged 70–79 yeas was 2.96 (95% CI: 2.10–4.18), and that for overestimation was 0.52 (95% CI: 0.35–0.79), compared to women aged20–29 years. Age is the most important factor associated with weight perceptions amongKorean women, affecting both underestimation and overestimation of weight status. amongKorean women, affecting both underestimation and overestimation of weight status.
