Exploring the Spatial Distribution of Rheumatic Diseases and Its Correlation With Temperature and Humidity Among Middle-Aged and Elderly Adults in China

Sociodemographic and health system factors associated with variations in hospitalization costs for rheumatic diseases in adults aged 45 years and older: A cross-sectional study of provincial health accounts in Jiangsu Province, China

AIM

To report the cost of hospitalization and the associated risk factors for rheumatic diseases in middle-aged and elderly patients in China.

METHODS

The study participants included inpatients from hospitals of various levels in the Jiangsu Province Health Account database in 2016. Participants were selected by using a multistage sampling method. Patients <45 years of age were excluded, and patients hospitalized for rheumatic diseases were identified according to the 10th edition of the International Classification of Diseases. Generalized linear models were used to analyze the sociodemographic characteristics related to the hospitalization costs of patients with rheumatic diseases.

RESULTS

The study included 3696 patients. The average cost of hospitalization for patients with rheumatic diseases was USD 4038.63. Female sex, a long length of stay, age between 65 and 74 years, free medical care, not being covered by the Urban-Rural Residents Basic Medical Insurance, and a high hospital level were associated with high hospitalization costs.

CONCLUSION

This study examined hospitalization costs and relevant influencing factors in middle-aged and elderly patients with rheumatic disease in China. Our findings are useful for further research on costs of disease and the economic evaluation of strategies to prevent rheumatic disease.

Association of indoor dampness indicators with rheumatic diseases/symptoms in older adults: A comparative cross-sectional study in Chongqing and Beijing

Dampness is strongly associated with rheumatic diseases, which particularly affect the older adults. Tackling dampness is therefore important, especially given that climate change is expected to exacerbate rheumatic diseases; however, limited studies have compared the risk of rheumatic diseases in older adults based on humidity levels across different regions. To explore this, a comparative cross-sectional study was conducted to collect information on the residential characteristics, lifestyles, and health outcomes of 2000 individuals aged 60-74 years from Chongqing and Beijing. From this data, we tested for an association between six indoor dampness indicators and rheumatic related diseases/symptoms. The results showed that the risk values for joint pain were higher in Chongqing than in Beijing. Moreover, the risk of joint stiffness increased more strongly in Chongqing than in Beijing as the cumulative number of dampness exposure indicators increased. The key indoor dampness indicators affecting rheumatic diseases were different for Chongqing and Beijing. Overall, this study compared the risk of rheumatic diseases in older adults in the north and south of China because of dampness exposure and, from these, provided suggestions for modifying the indoor environments to prevent or reduce rheumatic symptoms.
