Prospective Cohort Study of Chronic Diseases in South China

Healthy Chinese residents from South China will be recruited and followed up for at least 4 years to evaluate the association between climate, diet and lifestyle and risks for the development of chronic diseases. Physical examination, questionnaire survey and biological sample collection will be conducted at baseline and the incidence of chronic diseases will be investigated during follow-up.

Detailed Description

110,000 adult Chinese (35 to 74 years old) without chronic diseases and major disability who have been living in South China including Guangdong, Fujian, Guangxi and Hainan for more than 5 years will be recruited. All participants will be prospectively followed up for the incidence of chronic diseases (stroke, coronary heart disease, malignant neoplasms, chronic obstructive pulmonary diseases, diabetes and hypertension) and their risk factors (impaired glucose tolerance and obesity). Information about socio-demographic, diet, lifestyle, psychological status, medical history and current medication will be collected by questionnaires. Physical examinations including height, weight, waist and hip circumferences, blood pressure, fat mass and vital capacity will be conducted. Besides, blood, urine and fecal samples will be collected for further analysis. Annual meteorological data throughout the study period will also be collected. The associations between climate, diet and lifestyle and risks for chronic diseases will be evaluated.
