Nghiên cứu cắt ngang được tiến hành năm 2017, với phương pháp chọn mẫu chùm (PPS) để chọn30 xã/phường tại 8 huyện/thành phố thuộc tỉnh Thái Bình vào nghiên cứu. Điều tra trên 1450 ngườitrưởng thành ≥25 tuổi, kết quả cho thấy:Tỷ lệ mắc tăng huyết áp là 29,8%, nam chiếm 36,5% cao hơn so với nữ (22,0%), (p<0,05).Một số nguy cơ tim mạch: nam giới từ 55 tuổi trở lên (36,1%), nữ giới từ 65 tuổi trở lên (16,2%). Giađình có người mắc bệnh tim mạch sớm chiếm 20,5%. Thói quen ăn mặn (61,9%), ăn ít rau quả (53,9%),ít hoặc không vận động thể lực mức độ vừa (43,8%), uống nhiều rượu (37,4%); béo bụng chiếm 36,1%,thừa cân béo phì (19,8%), có rối loạn Lipid máu (15,9%), có bệnh đái tháo đường (6,5%).Có 63,4% số người có từ 1-2 yếu tố nguy cơ tim mạch; có từ 3 yếu tố nguy cơ trở lên chiếm 16,2%;đã có biến chứng hoặc có bệnh tim mạch chiếm 5,2%.Từ các kết quả nghiên cứu trên cũng đã cho thấy, cần thiết phải tăng cường các hoạt động truyềnthông về các yếu tố nguy cơ tim mạch để phòng chống bệnh có hiệu quả nhất.

Điều tra trên 1450 ngườitrưởng thành ≥25 tuổi, kết quả cho thấy:Tỷ lệ hiện mắc tăng huyết áp là 29,8%, trong đó nam giới chiếm 36,5%, cao hơn so với nữ là 22,0%(p<0,05), chủ yếu là tăng huyết áp độ 1 (42,3%), độ 2 chiếm 35,4% và độ 3 chiếm 22,3%.Tỷ lệ tăng huyết áp có xu hướng tăng dần theo nhóm tuổi, ở nhóm tuổi từ 70 trở lên chiếm tỷ lệ caonhất (36,4%), nhóm tuổi 60-69 chiếm 34,8%, nhóm tuổi 40-59 chiếm 31,5% và thấp nhất là nhómtuổi 25-39, chiếm 16,1% (p<0,05).
A cross-sectional study was carried out in 2017, with the method of cluster sampling (PPS) to select30 communes/wards in 8 districts/cities in Thai Binh province. A total of 1450 adults from 25 ago ormore the results showed that:The prevalence rate of hypertension was 29.8%, of which men account for 36.5%, 22.0% higherthan that of women (p<0.05), mainly high blood pressure level 1 (42.3%), level 2 (35.4%) and level3 (22.3%).The rate of hypertension tends to increase gradually by age group, the group aged 70 and overaccounts for the highest proportion (36.4%), the age group 60-69 was 34.8%, the age group 40-59was 31.5% and the lowest of 25-39 age group (16.1%) (p<0.05).

A total of 1450 adults from 25 ago ormore the results showed that:The prevalence rate of hypertension was 29.8%, of which men account for 36.5%, 22.0% higher thanthat of women (p<0.05)Some cardiovascular risk factors: males 55 years and older (36.1%), females 65 years and older(16.2%). Families with people suffering from early cardiovascular disease account for 20.5%.Habit of salty eating (61.9%), Eating less vegetables (53.9%), Little or moderate physical inactivity(43.8%), drinking a lot of alcohol (37.4%); abdominal obesity accounts for 36.1%, are overweightand obese (19.8%), have dyslipidemia (15.9%), have diabetes (6.5%) There are 63.4% of peoplewith 1-2 cardiovascular risk factors; having 3 or more risk factors, accounting for 16.2%; Havingcomplications or cardiovascular disease accounts for 5.2%.From the research of results also showed that it is necessary to increase communication activities oncardiovascular risk factors for the most effective prevention of the disease.
The aims of study was formulation and evaluation of berberin (BBR) loaded proliposomes by spray-drying method. BBR proliposomes were evaluated for appearance, spray-drying efficiency, morphology and differential scanning calorimetry (DSC). Liposomes, obtained after hydration, were evaluated for particle size, size distribution, morphology and entrapment efficiency. The results showed that BBR proliposomes were prepared by spray-drying method with molar ratio of Hydrogenated soy phosphatidyl choline (HSPC): Sodium deoxycholat (NaDC): vitamin E (vtE): BBR = 7: 1: 6: 6. Mixture of manitol and Aerosil at weight ratio of 97:3 was used as carrier. Results of DSC showed that berberin was dispersed molecularly into proliposomes powder. BBR liposomes, obtained after hydration, had average particle diameter of about 29 μm and entrapment efficiency was 22.23%.
