[The relationship between nutrition and prevalence of coronary events and stroke in urban and rural areas of Shijiazhuang].

The prevalence of coronary events was 64.5/100,000 in the urban of shijia zhuang and it was higher than 23.8/100,000 in rural. Contrary to the coronary events, the prevalence of stroke in urban (159.6/100,000) was lower than that in rural (170.2/100,000). The paradox was studied with their relation to nutrition. The SBP and DBP levels, hypertension rate, serum cholesterol, BMI and dietary saturated fatty acid and cholesterol in urban were higher than that in rural. They were risk factors especially to coronary events. The urban inhabitants had high animal protein intake and higher serum amino acids and higher SO4 excreted in daily urine than that of the rural inhabitants. The result suggests that the higher animal protein intake may be preventive factor for stroke in urban inhabitants.
