“…We identified other factors that may predict COPD development. First, age and smoking history are significantly correlated with COPD development and survival, as shown in previous studies . Second, Charlson's comorbidity index was also an independent risk factor for COPD development and survival.…”

Background Sarcopenia may worsen disease progression and lead to poor outcomes in chronic obstructive pulmonary disease (COPD). Objectives We aimed to determine the effect of BMI on the development of COPD and mortality. Methods We enrolled 437 584 participants registered in the physical health check‐up cohort database of the Korean National Health Interview Survey from 2002 to 2003, and we defined COPD diagnosis based on the ICD‐10 code and prescribed medication. BMI (kg m−2) classified them to five groups (low BMI < 18.5, normal BMI 18.5–23, overweight 23–25, obesity 25–30, severe obesity ≥30) at baseline. Results Participants in the low BMI group had a significantly higher rate of COPD development for 13 years (7.6%) than those in other groups (3.4–4.1%, P < 0.0001). Amongst never or light smokers, COPD development in the low BMI group (5.6–6.7%) was significantly higher than that in other groups (2.8–4.7%). Similarly, amongst participants with a smoking history of ≥30 years, COPD development in the low BMI group (20.1%) was higher than those in other groups (8.4–12.4%). On multivariable analysis, normal or higher than normal body weight was significantly protective against the development of COPD (hazard ratio [HR], 0.609–0.739,) compared to low BMI. COPD‐free‐survival (HR, 0.491–0.622) and overall survival (HR, 0.440–0.585) were also better in them compared to those with low BMI (all P < 0.0001). Conclusions Low BMI is an important risk factor for COPD development and mortality. Maintaining adequate body weight may reduce the risk for COPD development and mortality.

“…At each visit, all exacerbations were recorded by a study physician or trained nurse. An exacerbation was defined as moderate when any worsening of respiratory symptoms led to treatment with systemic corticosteroids, antibiotics, or both, and severe if it led to a hospital admission or an emergency department visits [28,29].…”

Background/Aims: Despite increasing awareness of the burden of chronic obstructive pulmonary disease (COPD) in women, knowledge regarding gender differences in COPD outcomes is limited. Therefore, we aimed to evaluate whether COPD outcomes, including exacerbations, lung function, and symptoms differ by gender. Methods: We recruited patients with COPD from two Korean multicenter prospective cohorts. After propensity score matching, the main outcome, the incidence of moderate or severe exacerbations was analyzed using a negative binomial regression model. We also assessed changes in lung function and symptom scores including the St. George's respiratory questionnaire for COPD (SGRQ-C), COPD assessment test (CAT), and the modified Medical Research Council (mMRC) dyspnea score. Results: After propensity score matching, 74 women and 74 men with COPD were included. The incidence rates of exacerbations in women and men were not significantly different (incidence rate ratio, 1.49; 95% confidence interval [CI], 0.88 to 2.54). There was no significant difference in the incidence rates adjusted for medication possession ratios of long-acting muscarinic antagonists, long-acting β-agonists, and inhaled corticosteroids during the follow-up period (incidence rate ratio, 1.47; 95% CI, 0.86 to 2.52). Rates of decline in post-bronchodilator forced expiratory volume in 1 second and forced vital capacity did not differ between women and men during 48 months of follow-up. The changes in scores on the SGRQ-C, CAT, and mMRC Questionnaire in women were also similar to those in men. Conclusions: We observed no gender differences in the rate of exacerbations of COPD in a prospective longitudinal study. Further studies are needed to confirm these findings in the general COPD population.

“…Morbidity and mortality rates of COPD are increasing steadily, most likely due to exposure to cigarette smoke, air pollution, but also because of ageing of the population. Morbidity and mortality rate vary from country to countries and region to region [2,4,5].…”

Effects of meteorological conditions on mortality from chronic obstructive pulmonary disease

et al. 2020

Introduction/Objective. Previous studies have confirmed the effect of different meteorological parameters on patients suffering from lung diseases. The objective of the study is to investigate the impact of meteorological phases on the death rate from chronic obstructive pulmonary disease (COPD). Methods. The data on the number of deaths caused by COPD and meteorological phases during a five-year period (2011?2015) in Sumadija District (Central Serbia) were obtained from the Republic Hydrometeorological Service and the Center for Biostatistics and Informatics of the Kragujevac Institute of Public Health. Results. A statistically significant correlation was determined between certain meteorological phases and COPD death rate. The highest death rate was determined during colder months, February and March. The lowest death rate was detected during the warm months (June?September). Although men died more often from COPD than women, the death rate of women showed a considerable increase during the five-year period. Conclusion. COPD death rate is highly dependent on the season of the year and might be associated with certain meteorological phases. There is a need for further research of the impact of meteorological phases on the morbidity and mortality from COPD.
