Results The rates of morbidity, awareness, medication and control for hyperlipidaemia were 53.97%, 28.05%, 13.05% and 10.03% respectively. Those for hypertension were 52.33%, 64.29%, 57.53% and 19.9% respectively. For diabetes, 13.63%, 71.23%, 68.39% and 32.73%. The morbidity rates of hypertension and diabetes increased with the advancing age, the morbidity of hyperlipidaemia decreased with the advancing age, and were all higher in the urban population than in the urban population. The rates of awareness, treatment and control for major chronic diseases were all higher in the urban population than the rural counterpart and were lower in the youth than the elders. The morbidity rates of lower extremity atherosclerosis, coronary heart disease and stroke were 11.0%, 6.0% and 4.4% respectively.
