[A dietary intervention study on the hypertensive high risk population in a northern rural area of Beijing].
To investigate the relationship between optimal living mode, healthy dietary pattern and the incidence of primary hypertension, a dietary intervention study on hte hypertensive high risk population was carried out in Fangshan district of Beijing during 1997-1999. The subjects were divided into two groups: control group and intervention group. A 3-day-dietary-recall combined with weighing method and a healthy diet education program were used in the study. The results indicated that the dietary pattern was not reasonable in the hypertensive high risk population. After two-year-intervention, the dietary pattern of people in the intervention group has changed distinctively. Compared with the results in 1997, the dietary risk factors decreased obviously in the intervention group, but increased in control group, such as high energy, fat, oil and cholesterol which can promote hypertension. Furthermore, in the past two years, the number of over weight + obese people increased by 24.6% in control group, but was no change in the intervention group. The intervention group subjects experienced an average decline of 3.7 and 5.1 mmHg of systolic blood pressure(SBP) and diastolic blood pressure(DBP) respectively, and new cases of hypertension observed in the intervention group were significantly lower than in control group. Thus it can be considered that the dietary intervention may be effective for the high risk population and play a very important role in the prevention of hypertension.
