Common Diseases, Rare Diseases
Conditions
Brief 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.
Detailed 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| age-specific prevalence rate | between January 1, 2017 and December 31, 2021 | 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. |
| sex-specific prevalence rate | between January 1, 2017 and December 31, 2021 | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| total cost of hospitalization | between January 1, 2017 and December 31, 2021 | Total cost of hospitalization and deductibles for the total population and for each age group of diseases are described by mean (SD) values. |
