RESUMO
Objective To confirm whether community management of hypertension could improve blood pressure control in Chongqing.Methods Cluster sampling method was used to select 5283 adults from 20 community healthcare centers in Chongqing.Matched t test was used to analyze the changes of blood pressure before and after the intervention.x2 test analysis was performed to compare the rate of normal blood pressure.Results The average age of 5283 participants was (60.5 ± 11.0) years old.Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly decreased after intervention (total population:t values were 16.98 and 13.80,respectively; male:t values were 12.58 and 10.66,respectively; female:t values were 11.60 and 9.10,respectively; all P ＜ 0.05).The most significant decrease in SBP was found in 50-59 y age group (t =15.29,P ＜0.05),followed by 40-49 y age group (t =9.22,P ＜0.05).The control rate of hypertension was increased by 5.3％ after 1 year's intervention (x2 =134.5,P＜0.05),except for 60-69 y age group and ≥70 y age group (x2 values were 2.5 and 1.7,respectively ; both P ＞ 0.05).Conclusion Our results show that standardized management of hypertension in communities can decrease the level of blood pressure and increase the control rate of hypertension.
