  Figure 1. BMI distribution in heart failure (4 subgroups). Distribution of BMI subgroups (4 subgroups) in general health check-up population and heart failure patients. The obese group accounted for 43.3% of the HF population, and it was higher than that of the general health check-up population (32.9%). General health check-up data of National health insurance service from Korean Statistical Information Service (2010−2021).

  Figure 2. BMI and sex distribution in heart failure. Distribution of BMI subgroups (4 subgroups) by sex in general health check-up population and heart failure patients. The proportion of obese people with a BMI over 25 kg/m2 in HF was 42.3 and 44.2% in men and women, respectively, and it was also higher than that of the general health check-up population (38.5 and 26.2% in men and women, respectively) (A). The incidence of HF is higher in women across all BMI subgroups compared to the general population (B).

  Figure 3. Distribution of BMI subgroups by age in heart failure. Analysis by age in heart failure patients (A) and general health check-up population (B). The combined frequency of obesity and extreme obesity groups was the highest in those in their 60s (4561), followed by those in their 70s (3719) and 50s (3658), respectively, in the HF group. However, in the same age group, the proportion of obesity and extreme obesity groups was the highest in their 40s (50.4%), followed by those in their 50s (48.4%) and 60s (47.9%), respectively (A). Age groups with high proportion of obesity were similar to the health check-up population (40s–60s of HF group vs. 30s–70s of check-up group) (B). General health check-up data of national health insurance service from the Korean Statistical Information Service (2010–2021).

  Figure 4. Distribution of BMI subgroups by age and sex in heart failure (2006–2015). Analysis by age and sex in heart failure patients (A,B) and general health check-up population (C). In the same age group, the proportion of obesity was the highest in men in their 40s (57.7%) and 30s (57.3%), and women in their 60s (52.2%) in heart failure. The proportion of the obese group has declined with age in older people, and on the contrary, that of normal and underweight groups has gradually increased in the same age group in both sexes (B). The pattern of the proportion of obesity by age and sex was similar to that of the health check-up group of the general population (C). General health check-up data of national health insurance service from Korean Statistical Information Service (2010–2021).

  Figure 5. Distribution of age and sex according to BMI subgroups in heart failure. The underweight group increases with age in both men and women, and the proportion of high-aged group (over 80 years old; dark blue bar) in the underweight group of women is much higher than that of men (A). The underweight group (red line) is gradually increasing as the patients get older in both men and women (B).
