Decline of the chronic respiratory disease mortality in the WHO Western Pacific Region

Background:
Non-communicable diseases (NCDs) are major cause of death all over the world killing 41 million of the 57 million deaths (72%) in 2016. According to World Health Organization (WHO) Director General the biggest decrease in NCD mortality between 2000 and 2019 globally were for chronic respiratory diseases (CRDs) a 37% decline. The WHO Western Pacific Region (WPRO) made the biggest gains against CRD a 55.9% drop. We analysed CRD mortality in the WPRO comparing with other WHO regions.
Methods:
Assessment of the risk factors was made in all WHO countries mainly in 2016. Lifestyle modifications concerning tobacco use, unhealthy diet, physical inactivity and harmful use of alcohol in 2020. We used WHO assessment of ambient and household air pollution attributable to chronic obstructive pulmonary disease (COPD) mortality.
Results:
WPRO comprises 27 countries, 10 high-income countries (HIC) and 17 middle-income countries (MIC). A total of 52 countries in other WHO regions belong to HIC and 86 countries to MIC. No difference was found in the tobacco demand-reduction measures. Clear difference was demonstrated in the prevalence of the raised blood pressure (RBP) which was lower in the WPRO. In the WPRO HIC every fifth has RBP while in other regions it was every forth. Similar difference was observed for MIC. COPD mortality linked to air pollution was twice higher in the WPRO. It was highest in MIC. CRD management probably plays a crucial role in the decline of the observed mortality in the region since numerous WHO global, regional and national prevention and management CRD approaches and activities have been successfully initiated and implemented there. WHO Global Alliance against Chronic Respiratory Diseases (GARD) was successfully initiated in Beijing in 2006. Two subsequent global GARD meetings held in Seoul [2007] and Beijing [2019] had a tremendous impact on the CRD awareness, prevention and control strategies in the region. These events have stimulated development of the national CRD programmes. Beijing's declaration "Call for action for lung health" stressed the better management of CRD at primary healthcare level.
Conclusions:
Better RBP control, improved prevention, diagnosis and treatment of CRD could contribute to the observed decline of premature CRD mortality in the region.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
