Epidemiology of chronic noncommunicable diseases and evaluation of life quality in elderly

Chronic noncommunicable diseases (NCDs) are the leading cause of death, accounting for 70% of global deaths. Also referred to as chronic diseases, NCDs mainly include cardiovascular disease (such as heart disease and stroke), cancer, chronic respiratory disease (such as chronic obstructive pulmonary disease and asthma), and diabetes. The incidence of NCDs is rising over time, becoming one of the most important threats to human health. As a measurement of quality of life, scales can reflect the entire health status of patients. But there are still many disadvantages in the multidimensional health status of elderly patients with chronic diseases, so it is of great significance to develop a simple and practical multidimensional health scale of good reliability and validity for chronic diseases in the elderly.
