Abstract
Objective To improve the dietary patterns of overweight or obese middle ―aged and aged people with hypertension in Zhangfang Village of Fangshan District of Beijing by adding a fixed formula of whole grains, nuts, beans, ginseng,jujube and other food ( referred to as the food powder of anti ― atherosclerosis ), and to observe its effects on the patients'blood pressure,body composition and blood lipid. Methods From 27th June 2015 to 11th October 2015,from the original villagers databases of 245 middle ―aged and aged people(aged between 45 and 75)in Zhangfang Village Fangshan District of Beijing,30 overweight or obese patients with grade one hypertension were selected as the research objects according to the inclusion criteria. The patients were divided into group one and group two by random number table method and each group had 15 cases. Cross―intervention study was made. Group one first entered the intervention stage and used the food powder of anti―atherosclerosis for supplement. At the same time group two entered the control stage and maintained the original dietary pattern. The above stage lasted for six weeks. Then in the following two―week wash―out period,group one recovered the original dietary pattern, but group two kept the original dietary pattern. At the beginning of the ninth week, group two entered the intervention phase,while group one was in the control stage for six weeks. Finally,24 patients(11 patients in group one,13 patients in group two)completed the test. Blood pressure,body composition level,blood lipid profile level,and dietary energy intake level were measured before the test(T0),at the end of the sixth week(T1)and at the end of the fourteenth week(T2) respectively. Results In group one,the systolic pressure at T1 was lower than that at T2,the diastolic pressure at T0 was lower than that at T2(p〈0. 05);in group two,the diastolic pressure at T0 was lower than that at T2(p 〈0. 05);the systolic pressure in group two at T1 was higher than that in group one(p〈0. 05). In group two,WHR and VF at T0 were greater than those at T1,and BF,WHR and VF were less than those at T2(p〈0. 05). The TG level in group two at T2 was lower than that in group one(p〈0. 05). In group one,the intake of protein,dietary fiber(DF),vitamin B1,mono unsaturated fatty acid (MUFA),poly unsaturated fatty acid(PUFA)at T0 was lower than that at T1,and the intake of total energy,protein,DF, vitamin B1 and PUFA at T1 was lower than that at T2,and the intake of vitamin B1 at T0 was greater than that at T2(p 〈0. 05). In group two,the intake of total energy,protein,fat at T0 was greater than that at T1,and the intake of total energy, protein,fat,DF,Zn,PUFA was less than that at T2,and the intake of DF and PUFA was lower than that at T2(p〈0. 05);the intake of total energy,carbohydrate,protein,fat,DF,Se,Zn,vitamin B1 ,MUFA and PUFA in group two at T1 was less than that in group one(p〈0. 05);the intake of PUFA in group two at T2 was greater than that in group one(p〈0. 05). Conclusion For overweight or obese middle―aged and aged patients with grade one hypertension after supplementation of food powder of anti―atherosclerosis,the dietary pattern is improved when the intake of energy properly increases. It can improve the body composition,lower the level of TG and has the tendency to decrease the blood pressure. When the intake of energy increases significantly,the dietary structure cannot be improved,and this means the body composition will not be improved,the level of TG will not be lowered and blood pressure will significantly increase.关键词
