Geochemical environment and health problems in China.

Area of Science:

• Environmental health
• Epidemiology
• Geography

Background:

• China's vast territory and complex environment harbor numerous endemic diseases.
• Key endemic diseases include Kaschin-Beck disease, Keshan disease, iodine deficiency, endemic fluorosis, and hepatic carcinoma.
• Disease distribution exhibits distinct geographical patterns.

Purpose of the Study:

• To model health problems linked to China's geographical environment.
• To emphasize the critical need for ongoing research in this field.

Main Methods:

• Analysis of the relationship between geographical factors (climate, geology, soil, water) and endemic diseases.
• Investigation of drinking water quality as a primary environmental determinant.
• Exploration of dietary factors and nutritional improvements.

Main Results:

• Geographical environment significantly influences the prevalence and distribution of endemic diseases in China.
• Drinking water quality is a critical factor, with pollution or mineral imbalances posing health risks.
• Improving drinking water and food quality can mitigate or eliminate certain diseases.

Conclusions:

• A strong correlation exists between China's geographical environment and endemic disease patterns.
• Continued research is essential for understanding and addressing these geographically influenced health issues.
• Interventions focusing on water and food quality show promise for disease reduction.
