目的探讨合理的生活方式和膳食结构与原发性高血压发病的关系及其在高血压防治中的应用。方法于 1 997～ 1 999年对上海南市区 1 0 2名高血压高危对象进行了膳食干预研究。结果经过两年的合理膳食干预后 ,对照组中可促进高血压发生发展的膳食营养因素明显增加 ,而干预组则明显减少或维持原有水平。两年间 ,干预组平均收缩压和舒张压水平分别下降了 3.8和 2 .9mm Hg,而对照组的血压水平没有明显变化。结论通过膳食综合干预可以改善城市社区居民的膳食结构 ,并可降低血压水平 。

Objective To explore the relationship of optimal lifestyle and healthy dietary pattern with primary hypertension.Methods A dietary intervention study in high risk population of hypertension was carried out in Nanshi district of Shanghai during 1997～1999. 102 subjects were respectively divided into control and intervention group.A 3 day recall of food intakes combined with diet weighing survey and a healthy diet education program were conducted in the study.Results After two year intervention,the intakes of energy,fat,sodium and cholesterol obviously increased in control group,but decreased or stood in intervention group.The oil intake decreased significantly in intervention group,but stood in control.During the past two years,the subjects of intervention group experienced a mean decline of 3 8 and 2 9 mmHg of systolic blood pressure (SBP) and diastolic blood pressure (DBP) respectively.
