INTRODUCTION
Hypertension, particularly pulse pressure [PP] is a major risk factor for end-stage renal disease. However, the effect of individual components of hypertension namely PP, systolic [SBP] and diastolic blood pressure [DBP] on kidney function, in the general African population is unknown.
METHODS
Data were collected on 944 participants [aged 40-75 y], living in villages in the area around the city of Kumasi, Ghana, on demographics, medications, height, weight, BP and 24-hour creatinine clearance (CrCl).
RESULTS
The demographic and clinical characteristics were: age 55(11) [mean (SD)] years, females 62%, rural village-dwellers 52%, diabetes 1·5%, BMI 21(4) kg/m, 24-hourCrCl as a measure of glomerular filtration rate (GFR) 84(23) ml/min/1.73 m. 29% had BP >140/90 mmHg; SBP and DBP were 125/74(26/14) mmHg, PP was 51(17) mmHg. PP increased with age by 0.55(95% CI: 0.46,0.64) mmHg/year. PP was higher (53(17) v 49(15) mmHg; p < 0.001) in the semiurban participants. GFR decreased both with increasing PP [-0.19 (-0.27,-0.10 ml/min/1.73 m/mmHg; p < 0.001] and SBP [-0.09 (-0.14,-0.03) ml/min/1.73 m/mmHg; p < 0.001] but there was no significant relationship with DBP [-0.04 (-0.15,0.06)]. After adjusting for SBP, the relationship between GFR and PP became steeper [-0.31 (-0.50,-0.12) ml/min/1.73 m/mmHg; p < 0.001]. Using multivariate regression analysis that included PP, age, gender, BMI, only increasing age [-0.75 (-0.88,-0.62)] and decreasing BMI [0.49 (0.16,0.81)] were associated with decreased kidney function.
CONCLUSIONS
In this homogeneous West-African population, PP increased with age and had a steeper relationship with declining kidney function than SBP or DBP.
引言
高血压，尤其是脉压（PP）是终末期肾病的主要危险因素。然而，在非洲普通人群中，高血压的各个组成部分，即PP、收缩压（SBP）和舒张压（DBP）对肾功能的影响尚不清楚。
方法
收集了居住在加纳库马西市周边地区村庄的944名参与者（年龄40 - 75岁）的人口统计学信息、用药情况、身高、体重、血压和24小时肌酐清除率（CrCl）数据。
结果
人口统计学和临床特征如下：年龄55（11）[均值（标准差）]岁，女性占62%，农村居民占52%，糖尿病患病率1.5%，体重指数（BMI）21（4）kg/m²，以24小时CrCl作为肾小球滤过率（GFR）的衡量指标为84（23）ml/min/1.73m²。29%的人血压>140/90 mmHg；SBP和DBP分别为125/74（26/14）mmHg，PP为51（17）mmHg。PP随年龄增长每年增加0.55（95%置信区间：0.46，0.64）mmHg。半城市参与者的PP更高（53（17）对49（15）mmHg；p<0.001）。GFR随PP升高[-0.19（-0.27，-0.10）ml/min/1.73m²/mmHg；p<0.001]和SBP升高[-0.09（-0.14，-0.03）ml/min/1.73m²/mmHg；p<0.001]均下降，但与DBP无显著关系[-0.04（-0.15，0.06）]。在对SBP进行校正后，GFR与PP之间的关系变得更显著[-0.31（-0.50，-0.12）ml/min/1.73m²/mmHg；p<0.001]。使用包括PP、年龄、性别、BMI的多变量回归分析，仅年龄增长[-0.75（-0.88，-0.62）]和BMI降低[0.49（0.16，0.81）]与肾功能下降相关。
结论
在这个同质化的西非人群中，PP随年龄增长，且与肾功能下降的关系比SBP或DBP更显著。
