Abstract [en]

Background

Population ageing is one of the challenges facing the world nowadays. However, China is known as one of the countries with the largest population number associated with an increase in aged people percentage. This study aims to assess the prevalence of chronic respiratory symptoms (cough, sputum ,wheezing and dyspnea), the prevalence of chronic obstructive pulmonary disease (COPD) and associated comorbidities according to selected age groups, sex, and smoking status in population aged 50 years and older in China. In addition to examine the association between selected comorbidities (diabetes, hypertension, arthritis, difficulties in walking, stroke, depression) and chronic obstructive pulmonary disease.

Methods

The study was based on SAGE (World Health Organization on global Ageing and adult health data) and conducted among 12 765 participants who answered a set of self-reported questions through the individual questionnaire; such as if they have any chronic respiratory symptoms (cough, sputum/phlegm, wheezing, dyspnea), and they were also asked if they have ever been diagnosed with diseases or disorders as (COPD, asthma, hypertension, stroke, angina, arthritis, depression, diabetes and difficulties in walking) by a physician/doctor. Prevalence of chronic respiratory symptoms, chronic obstructive pulmonary disease (COPD) and common selected comorbidities were calculated. Simple Logistic regression was executed to evaluate the association between chronic obstructive pulmonary disease and age-related comorbidities and to evaluate the relation between smoking status and chronic respiratory symptoms.

Results

Chronic cough showed the highest percentage in the total Chinese population among chronic respiratory symptoms with overall (5.4%) by sex. The prevalence of chronic obstructive pulmonary disease was 8% in general Chinese population. Among age-related comorbidities, hypertension represented the greatest proportion with (26.5%), followed by arthritis (22.1%). The prevalence of respiratory symptoms has increased by age and was noticeably higher in last two age groups 75-79 years and 80+ years. Among comorbidities, the prevalence of hypertension, angina, stroke and difficulties in walking have elevated over age. Arthritis, angina, difficulties in walking and hypertension varied by COPD diagnosis significantly with estimated odds ratios, arthritis (OR =2.16 , 95% CI 1.89-2.46), angina (OR =2.07 , 95% CI 1.73-2.47) ; difficulties in walking (OR =1.99 , 95% CI 1.52-2.64) and hypertension (OR =1.58 , 95% CI 1.39-- iii -1.80). Smokers experienced the higher percentage of respiratory symptoms comparing to non –smokers, and smoking status was a predictor of respiratory symptoms and COPD.

Conclusion

Results from this study showed best estimations for the prevalence of respiratory symptoms, COPD and common comorbidities among elderly in China compared to other studies on Chinese national level. Chronic comorbidities were common among elderly population in China. Hence, earlier diagnosis and interventions are required. These comorbidities were common among COPD patients and varied by COPD diagnosis significantly. Therefore, it is vital to assess these conditions among COPD patients as earlier as possible in order to mitigate the disease burden.
