Clinical Trial Summary

The purpose of this study is to form a chronological map of common diseases and rare diseases in Chinese population by determining the prevalence of different diseases in each age group.

Description:

Studying the distribution of various diseases in specific populations can help explore the causes of diseases, elucidate the distribution patterns, and develop preventive and control measures. Based on an overall assessment of prevalence, the combination of relevant results with age at diagnosis for multiple diseases is important for further understanding of the distribution of diseases at the population level. Therefore, this study aims to form a chronological map of common diseases and rare diseases in Chinese population by determining the prevalence of different diseases in each age group, thus providing a reference for more effective prevention, diagnosis and treatment of diseases.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	age-specific prevalence rate	Age-specific prevalence rate stratified by sex were calculated by dividing the number of incident cases with a current disease by the total number of people in the study population during that time period.	between January 1, 2017 and December 31, 2021
Primary	sex-specific prevalence rate	Sex-specific prevalence rate stratified by age for 10-year bands were calculated by dividing the number of incident cases with a current disease by the total number of people in the study population during that time period.	between January 1, 2017 and December 31, 2021
Secondary	total cost of hospitalization	Total cost of hospitalization and deductibles for the total population and for each age group of diseases are described by mean (SD) values.	between January 1, 2017 and December 31, 2021
