“…BMI was based on self-reported height and weight and calculated as weight in kilograms divided by height in meters squared. Correlation coefficients between the measured and self-reported BMI in the subgroup of this survey were high (r = 0.92) [ 25 ]. Participants were categorized into four groups according to WHO Asian classification [ 26 ] based on their BMI as 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 ).…”

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

“…Second, BMI was calculated using self-reported height and weight. However, there was a high correlation coefficient between measured BMI and self-reported BMI in the 2016 KCHS (r = 0.92) [33]. Third, other indices reflecting adiposity, such as waist circumference, total body fat, and subcutaneous abdominal adipose tissue mass, were not included in this study, and further evaluation using these indices is needed.…”

Objective: Several previous studies have evaluated associations between body mass index (BMI) and self-rated health (SRH); however, the results were inconsistent. This study aimed to examine the association between BMI and SRH in Korean adults. Methods:The study was conducted in 214,997 adults who participated in the 2016 Korean Community Health Survey. Participants were categorized into four groups based on BMI: underweight (<18.5 kg/m 2 ), normal weight (18.5-24.9 kg/m 2 ), overweight (25.0-29.9 kg/m 2 ), or 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:There was a J-shaped association between BMI and poor SRH in both sexes, with the lowest risk observed in the normal weight group in both sexes. Compared with normal weight subjects, the age and lifestyle adjusted prevalence rate ratios for poor SRH were 1.61 (95% CI, 1.50-1.74) for underweight, 1.16 (95% CI, 1.11-1.21) for overweight, and 2.35 (95% CI, 2.13-2.58) for obese men; and 1.24 (95% CI, 1.17-1.32) for underweight, 1.26 (95% CI, 1.22-1.31) for overweight, and 1.77 (95% CI, 1.64-1.91) for obese women. Conclusions:In a cross-sectional study using a nationally representative survey, there was a nonlinear relationship between BMI and poor SRH. This relationship was more prominent in men than in women. Prospective studies are needed to further clarify the relationship between BMI and SRH.

“…Second, BMI was calculated from self-reported body weight and height. In a study based on the 2016 KCHS, the correlation between measured BMI and BMI calculated by self-reported body weight and height was 0.86 at ages ≥60 years, which was lower than at other ages [32]. Therefore, further studies using accurately measured data are needed.…”

Objectives: The purpose of this study was to evaluate the association between body mass index (BMI) and severe lower urinary tract symptoms (LUTS) in Korean males. Methods: This study was conducted on males aged ≥50 years who participated in the 2011 Korean Community Health Survey. LUTS severity was assessed using the Korean version of the International Prostate Symptom Score (IPSS) questionnaire, and was dichotomized as severe (IPSS >19) and non-severe (IPSS ≤19). BMI was divided into 6 categories: <18.5, 18.5-22.9, 23.0-24.9, 25.0-27.4, 27.5-29.9, and ≥30.0 kg/m 2 . To evaluate the relationship between BMI and LUTS, a survey-weighted multivariate Poisson regression analysis was performed to estimate prevalence rate ratios (PRRs). Age, smoking status, alcohol intake, physical activity, educational level, household income, and comorbidities were adjusted for in the multivariate model. Results: A U-shaped relationship was detected between BMI and severe LUTS. Compared with a BMI of 23.0-24.9 kg/m 2 , the PRR for a BMI <18.5 kg/m 2 was 1.65 (95% confidence interval [CI], 1.35 to 2.02), that for a BMI of 18.5-22.9 kg/m 2 was 1.25 (95% CI, 1.09 to 1.44), that for a BMI of 25.0-27.4 kg/m 2 was 1.20 (95% CI, 1.00 to 1.45), that for a BMI of 27.5-29.9 kg/m 2 was 1.11 (95% CI, 0.83 to 1.47), and that for a BMI ≥30.0 kg/m 2 was 1.85 (95% CI, 1.18 to 2.88). Conclusions: This study showed that both high and low BMI were associated with severe LUTS.
