The highest degree of correlation,both in Pearson correlation and multiple regression analysis,was found between U-Na and log-stroke mortality(P<.01 to P<.001).In multiple regression analysis,U-Na(P<.01 to P<.001),SFA(P<.05 to P<.01),and alcohol(P<.05)independently,significantly,and positively correlated with long-stroke mortality rates,and U-K correlated negatively (P<.05).The exceptions were SFA in both sexes in the age class 45 to 54 years,alcohol in both sexes in the age class 45 to 54 years and in women in the age class 55 to 64 years,and U-K in women in the age class 65 to 74 years.These results suggest that dietary factors,especially sodium and SFA,are of primary importance as determinants of stroke mortality at the population level. |
