| Abstract: |
| Objective：To study the relationship between diet nutrition and the prevalence rate of stroke. Methods：By force of stepwise regression analysis，we analyse the data of prevalence of stroke in 1986 and the cross-sectional study data of diet intake from 1984 to 1986 in 143 survey areas in China. Results: There was a negative association between protein, carbohydrate, calcium and the prevalence rate of stroke. By contrary, there was a positive association between other nutrition factors intake and the prevalence rate of the stroke. Conclusion: The dietary factors have some influences on the prevalence of stroke. High protein and high calcium intake are protective factors of stroke, on the contrary, vitamin A may be a risk factor of stroke. |
