“…[13][14][15][16] The association between objective and subjective measures of weight, height, and BMI was strong, which is consistent with findings from some previous studies. 16,17 Besides, as in other studies, 13,16,[18][19][20][21][22] underestimation of weight and height based on subjective data was observed. In the present study, this underestimation can be considered small, as mean differences of less than 1 kg for weight and of less than 1 cm for height were observed for children.…”

“…However, studies based on large samples actually use self-reported height and weight; furthermore, actual height and weight were assumed to be recorded as this study also was a self-reported survey performed using a computer. In addition, a previous study suggested that little discrepancy was found between self-reported and measured BMI in Asian adolescents [48]. Nevertheless, in future large studies, height and weight should be directly measured to improve assessment of weight perception.…”

BackgroundRapid physical and emotional growth occurs during youth. Adolescence is one of the most important periods for adapting to body change and establishing an ideal body image. Body change is an important and sensitive concern for adolescents, and the values and self-conception established at this time affect various aspects of the entire life. This study aimed to investigate the prevalence and trends of weight misperception among adolescents in Korea.MethodsWe analyzed raw data from the 2011 Korea Youth Risk Behaviour Web-based Survey-VII (KYRBWS-VII), in which 73,474 adolescents from the middle-school first grade to the high-school third grade (aged 12–18) participated. For the multivariate logistic regression model, the dependent variable was existence of misperception (yes/no) and independent variables were sociodemographic factors.ResultsWe found that the prevalence of weight misperception was 49.3% (overestimation, 23.7%; underestimation, 25.6%). Among male students, 65.0% underestimated their weight, whereas 62.2% of female students overestimated their weight. Multivariate logistic regression analysis revealed that gender (OR = 1.254; 95% CI = 1.214–1.294; p < 0.001) and socioeconomic status (OR = 1.173; 95% CI = 1.121–1.228; p < 0.001) were significantly associated with weight misperception. Compared with overweight/obese adolescents, adolescents whose BMI-based body weight was underweight or normal showed 2.386-times higher (OR = 2.386; 95% CI = 2.045–2.783, p < 0.001) and 32.804-times higher (OR = 32.804; 95% CI = 29.829–36.077, p < 0.001) body shape misperception, respectively.ConclusionsAn effective obesity intervention program for adolescents must reflect and monitor body shape perception as well as BMI, and should include subjects who overestimate as well as underestimate their weight.

“…Previous studies in Japan have shown that self-reported child weight and height is highly accurate [19]. BMI (kg/m 2 ) was calculated as weight (kg) over height squared (m 2 ).…”

BackgroundChildhood overweight and obesity is a growing health challenge in Japan and might be associated with childhood poverty.We aimed to investigate the association between low economic status and body mass index (BMI) and to reveal the mediators of this association among junior high school students in Japan.MethodsJunior high school students (N = 2968) from two cities in Shizuoka, Japan, were surveyed. Questionnaires assessed subjective economic status, weight, and height. Economic status was categorized into low and non-low, and BMI z-scores were calculated using the WHO Growth Reference. Multivariate regression analyses were conducted to determine the association between economic status and BMI z-scores, adjusted for covariates and stratified by gender.ResultsAmong girls, low economic status was significantly positively associated with BMI z-scores in the crude model (coefficient: 0.35; p = 0.001). In a model adjusted for breakfast skipping, the coefficient of economic status decreased by 28.57 % but remained significant (coefficient: 0.25; p = 0.017). In the final model adjusted for other possible covariates, low economic status remained significantly positively associated with BMI z-score (coefficient: 0.22; p = 0.044). The same association was not found for boys.ConclusionsLow economic status was positively associated with higher BMI among girls in junior high school in Japan, but this was not true for boys. Childhood poverty might be associated with overweight and obesity among adolescent girls in Japan. Health policies at junior high schools to discourage breakfast skipping might be effective for countering the association between childhood poverty and overweight in adolescent girls.Electronic supplementary materialThe online version of this article (doi:10.1186/s40608-016-0127-z) contains supplementary material, which is available to authorized users.
