“…Only one previous study was based on Korean. Noh et al assessed the relationship between BMI categorized as WHO Asian classification and SRH scores, and SRH scores were the highest in the normal-weight (18.5-22.9 kg/m 2 ) [23]. Compared to normal-weight, the odds ratio (OR) of poor SRH score was 1.60 in underweight, 1.08 in overweight, 1.72 in obese, and 3.97 in severely obese.…”

This study aimed to examine the association between body mass index (BMI) and self-rated health (SRH) in Korean adults. Methods The study included 214,997 adults who participated in the 2016 Korean Community Health Survey. Participants were categorized into four groups according to WHO Asian classification based on their BMI: underweight (<18.5 kg/m 2), normal-weight (18.5-22.9 kg/m 2), overweight (23.0-24.9 kg/m 2), obese (25.0-29.9 kg/m 2), and severely obese (�30.0 kg/m 2). Multivariate Poisson regression analysis with sampling weights and robust variance estimators was performed to evaluate the relationship between BMI categories and poor SRH. Results A J-shaped association was observed between BMI and poor SRH in both sexes. Compared to normal-weight subjects, the age, lifestyle, and comorbidities adjusted prevalence rate ratios (PRRs) in men for poor SRH were 1.73 (95% confidence interval [CI], 1.60-1.88) for underweight, 0.87 (95% CI, 0.83-0.92) for overweight, 0.98 (95% CI, 0.93-1.03) for obese, and 1.79 (95% CI, 1.63-1.97) for severely obese. In women, compared to normalweight subjects, the age, lifestyle, and comorbidities adjusted PRRs for poor SRH were 1.33

“…In Japan, similar to in Korea, underweight women view themselves as normal or overweight [ 28 ], and a high percentage of normal weight women believed themselves to be overweight [ 29 ]. In summary, many studies reported body image discrepancy, the pattern of which varies by different cultures and countries [ 30 ].…”

BackgroundThere are many studies examining the relationship between body image and weight status that compare Western and Asian countries. One limitation of these past studies was assuming that all Asian countries are a homogeneous group. To fill the gap in the literature, this study examined the relationship between body image and weight status between participants from two Asian countries.MethodsThis study utilized data from the 2010 module of the East Asian Social Survey from South Korea (n = 1576) and Taiwan (n = 2199), which contained questions related to body image. Body image was originally measured using a five-point Likert-type question, which was collapsed into three categories for the analysis. Weight status was derived from body mass index scores, which were calculated using self-reported weight and height. A set of multinomial logistic regression analyses were used to investigate the relationship between body image and weight status, stratified by country.ResultsA significant relationship between body image and weight status after controlling for relevant covariates was reaffirmed in this study in the South Korean and Taiwanese. Results indicated that the relationship between body image and weight status of the Taiwanese sample was similar to the relationship in the South Korean sample. However, the results from a further analysis showed that the strength of the relationship across the two Asian countries appeared to be different.ConclusionsThe weight over-perception was more evident in South Korea than in Taiwan. Females were more vulnerable to societal pressures for thinness and the misperception of the ideal body than males. Interventions to improve distorted body image perception were needed in both countries.

“…These values are higher than those reported previously for similarly aged Japanese elderly people (53.5%, 76.2%, and 27.9%, respectively, for elderly people aged 70-79 years) 17) . A possible explanation of this result can be that Taiwanese people have higher proportions of obese and severely obese (32.7%) compared to Japanese people (19.4%) 19) , but further research is required to confirm this possibility. Moreover, our findings indicated that the weight, muscle mass, and SMI were lower, while the age and body fat were higher in the LS group than in the non-LS group.…”

The aim of this study was to examine the relationship between locomotive syndrome (LS) and the physical characteristics of Taiwanese elderly people. Materials and Methods: Seventy-six untrained Taiwanese elderly individuals (31 male; mean age, 70.0 ± 7.1 years) were included in this study. Three functional tests, namely the Stand-Up test, Two-Step, and 25-question Geriatric Locomotive Function Scale, were used to assess the risk of LS. A total of 70 subjects were included in the LS group, while the other six subjects were included in the control (non-LS) group. Body composition (weight, body fat, muscle mass) was determined via bioelectrical impedance analysis using a domestic body composition analyzer. Body mass index and skeletal muscle mass index (SMI) were calculated. The binomial logistic regression analysis was performed with the presence/absence of LS as the dependent variable. Results: The prevalence of LS was 92.1% (26 male and 44 female) in this study. Body weight, muscle mass, and SMI were significantly lower in the LS group compared with the non-LS group. The body fat percentage in the LS group was significantly higher than that in the non-LS group. Logistic regression analysis showed that muscle mass was significantly related to LS (odds ratio = 0.824, p < 0.05). Conclusion: Community-dwelling Taiwanese elderly people who fulfill the diagnostic criteria for LS have lower muscle mass and higher body fat percentage. In particular, the decrease in muscle mass may be an effective indicator of increased risk of LS.
