| ObjectiveTo explore the effect of Internet + intervention technology on the control of blood pressure in high risk groups of hypertension in Haikou Haikou community,and to adopt a new management model,to advance the treatment of hypertension,prevent the occurrence of hypertension,and provide scientific basis for the prevention and treatment of cardiovascular diseases(CVD).MethodA total of 295 people at high risk of hypertension recruited between 1 July and 31 July of the 20212021 were randomly divided into three groups: the Blank Group,the traditional group and the Internet + Group,after 12 months of intervention,8 people in the three groups were lost to follow-up,the remaining 287 people were lost to follow-up,the rate of loss to follow-up was 2.7%.The Blank Group was the task group that did not adopt special intervention measures,and the community in which the intervention was carried out according to the “National Basic United States Public Health Service Standards(3rd edition)of Health Education Service Standards”.The traditional group is based on the blank group,in addition,the study group took the following traditional ways to intervene: holding a face-to-face lecture on hypertension,distributing a set of nutrition popular science books prepared and published by the Study Group,and distributing an oil pot.The Internet + Group,based on the intervention of the traditional group,also asked the subjects to download and install the“Nutrition Assistant” APP developed by the research group using Android smartphones to record their dietary intake in real time,at the same time,add the wechat Group and join the wechat Group for long-distance diet intervention and long-distance sports intervention.At the time of enrollment and 12 months after follow-up,the lifestyle,laboratory biochemical examination,physical measurement and dietary survey were carried out.In this study,the effect of blood pressure control was used to evaluate the outcome.There were many influencing factors related to blood pressure,including various physiological and biochemical indexes and dietary indexes,waist circumference,hip circumference,BMI,blood lipids,blood glucose,uric acid,folic acid,24-hour urine sodium and related dietary indexes were selected as the intermediate indexes of intervention effect evaluation.SPSS 21.0 software was used.Mean ± standard deviation(x ± s)was used to describe the measurement data of normal distribution.Analysis of variance and analysis of covariance were used to compare between groups Measures that did not conform to the normal distribution were presented as medians(P25,P75),with rank-sum tests for between-group comparisons and paired rank-sum tests for pre-and post-intervention comparisons.Count data adoption rate(%)was described.Chi-square test was used for comparison between groups.Mc Nemar’s exact test was used to test the difference of count data before and after intervention.The test level was α = 0.05,P < 0.05,the difference was statistically significant.Results1.A total of 295 subjects were enrolled,including 105 men(35.6%),190 women(64.4%),aged 64.69.5.73 years,systolic blood pressure 129.79 ± 9.59 mmgh,diastolic blood pressure 80.96 ± 6.78 mmgh.Subjects of different intervention groups,there were no significant differences in sex,age,family history of hypertension,education,occupation,marital status,drinking habit and regular exercise(P > 0.05).2.In the aspect of life habits,the drinking and regular exercise behaviors of the Internet + Group were improved after intervention,while the health behaviors of the traditional group had no significant change,the drinking rate of the blank group increased after intervention(P < 0.05).After intervention,the drinking rate of the Internet + Group(27.7%)was significantly higher than that of the traditional group(47.4%)and the regular exercise rate of the Internet + Group(36.6%)was significantly higher than that of the traditional group(21.1%)and the blank group(14.1%),the difference was significant(P < 0.05).After intervention,TC,LDL-C,blood glucose,uric acid,24 h urine sodium,SBP,DBP,waist circumference,hip circumference and BMI decreased,while folate and HDL-C increased in the Internet + Group In the traditional group,blood glucose and LDL-C decreased,uric acid and 24 h urine sodium increased TC,TG,LDL-C,blood glucose,uric acid,24 h urine sodium,SBP,DBP,waist circumference,hip circumference and BMI were increased,while folic acid and HDL-C were decreased in the control group,there were significant differences in TC,HDL-C,LDL-C,uric acid,folic acid,24 h urine sodium,SBP and DBP in the Internet + Group,the difference of HDL-C,LDL-C,SBP and DBP between the traditional group and the traditional group was statistically significant,there were significant differences in TC,uric acid,24 h urine sodium,SBP and DBP in Internet + Group(P < 0.05).3.After the intervention,the intake of cereals,potatoes,nuts,meat,aquatic products,oil and salt decreased in the Internet + Group,the intake of milk and dairy products,vegetables,fruits and eggs increased,while the intake of nuts and eggs decreased in the traditional group The intake of cereals,nuts,aquatic products,oil and salt increased,while the intake of milk,dairy products and vegetables decreased in the blank group,there were significant differences in the intake of eggs and salt between the Internet + Group and the traditional group(P < 0.05).4.In terms of energy and macronutrient intake,energy,carbohydrate,fat and protein intake decreased and dietary fiber intake increased in the Internet + Group after intervention The intake of energy,carbohydrate,fat and protein increased and the intake of dietary fiber decreased in the traditional group,there were significant differences in energy,carbohydrate and protein intake between the Internet + Group and the Blank Group,there were significant differences in energy and carbohydrate intake between Internet + Group and control group(P < 0.05).5.After intervention,the intake of sodium,magnesium,zinc and selenium decreased,while the intake of potassium,calcium and iron increased The intake of sodium,potassium,magnesium and zinc decreased and the intake of selenium increased in the traditional group,while the intake of sodium,magnesium,iron,zinc and selenium increased and the intake of potassium decreased in the blank group,there were significant differences in sodium and potassium intake between the Internet + Group and the blank group,and between the Internet + Group and the traditional group,there was significant difference in potassium intake between Internet + Group and control group(P < 0.05).6.After intervention,the intake of vitamin E,vitamin B1,vitamin B2,vitamin B6,vitamin C and folic acid increased in the Internet + Group,the intake of vitamin A decreased,the intake of vitamin B1 increased and the intake of folic acid decreased in the traditional group The intake of vitamin B1,vitamin B2,vitamin B12,vitamin C,vitamin D and folic acid decreased and the intake of vitamin A increased in the control group,the intake of vitamin B1,vitamin B2 and vitamin B6 in the Internet + Group was significantly different from that in the traditional group Compared with the traditional group,the intake of vitamin B6 in the Internet + Group was significantly different(P < 0.05).ConclusionCompared with the traditional intervention model,the Internet + intervention model can promote the improvement of the life style of the high-risk group of hypertension in the Haikou community,control of weight,blood pressure and other CVD-related indicators can also play a better effect.The dietary survey results showed that after intervention,the Internet + Group participants met the dietary guidelines for Chinese residents(2016)except for fruit,milk and dairy products,interventions for most food and nutrient intakes were positive,but some intakes such as nuts,fish,protein,zinc and vitamin A were reduced,therefore,we can consider to increase the number of interventions,extend the pre-1,000 time,strengthen the diet education,to gradually improve the residents’ healthy diet habits.To sum up,the Internet + intervention model can effectively promote the adoption of healthy lifestyle among high-risk groups of hypertension in Haikou communities,improve the dietary situation,effectively improve the blood pressure level and contribute to disease prevention.In the future research,we can update and update the dietary guidelines for Chinese residents according to the changes of national policies,keep up with the times,and provide more reasonable guidance for residents through the Internet +model,to achieve better results. |
