A series of biomarkers for each respondent are collected in this module. The measures include height, weight, waist circumference, lower leg length and arm length, blood pressure, lung capacity, and a timed sit to stand. CHARLS also collected dried blood spots (DBS), which will later be analyzed for C-reactive protein, hemoglobin and total and HDL cholesterol.
