摘要: 摘要: 目的 探讨不同短时收缩压变异性 (SBPV) 指标与老年人群肾小球滤过率 (eGFR) 的关系。方法 在参加开滦研究队列第3次健康体检的人群中, 采取整群抽样的方法随机抽取年龄≥60岁的开滦集团离退休员工进行24 h 动态血压监测等检查。在抽取的 3 064 例观察对象中, 符合入选标准 2 464 例, 最终纳入统计分析 1 405 例。SBPV 采用标准差 (SD)、 独立变异性 (VIM)、 极差 (MMD) 和平均真实变异性 (ARV) 4 种指标。采用多因素逐步线性回归分析不同短时 SBPV 指标与 eGFR 的关联。结果 (1) 在 1 405 例观察对象中, 平均年龄 (67.16±5.82) 岁, 其中男 933 例 (66.4%), 女 472 例 (33.6%)。(2) 将 24 h、 日间、 夜间平均收缩压 (SBP) 进行四分类 (<120 mmHg 为第一分类组, 120 mmHg≤平均 SBP<140 mmHg 为第二分类组, 140 mmHg≤平均 SBP<160 mmHg 为第三分类组, 平均 SBP≥160 mmHg 为第四分类组), 结果显示, 除 VIM 外, 随着平均 SBP 的增加, 其他短时 SBPV 指标 (SD、 MMD、 ARV) 均呈上升趋势。(3) 取 24 h、 日间、 夜间 SBPV 中位数 (P50 ) 分组, 高分位组的 eGFR 水平均低于低分位组, 除夜间 VIM 组外, 组间差异均有统计学意义。(4) 回归分析结果显示, eGFR 随着 24 h SBPV 指标 (SD、 MMD、 ARV)、 日间 SBPV 指标 (MMD、 ARV)的增加而降低 (标准化β分别为 -0.07、 -0.11、 -0.07, -0.12、 -0.07), 夜间 SBPV 指标均对 eGFR 无影响。结论 不同短时 SBPV 指标与eGFR 存在一定程度的关联。

Abstract: Abstract: Objective To investigate the correlation of short-term systolic blood pressure variability (SBPV) with esti⁃ mated glomeruar filtration rate (eGFR) in the elderly. Methods In physical examination for the third time of kailuan group, the method of cluster sampling was used to collect randomly retired employees, age ≥60 in kailuan group. The 24-hour am⁃ bulatory blood pressure monitoring was given to these objects. Finally, 1 405 participants with integral data were recruited in⁃ to the survey. SBPV indices were standard deviation of systolic blood pressure (SD), variability independent of the mean (VIM), maximum-minimum difference (MMD), and average real variability (ARV). Multivariate stepwise linear regression models were used to analyze the influence of short-term SBPV on eGFR. Results (1) Among 1 405 participants (67.16± 5.82) years, 933 individuals (66.4%) were male and 472 (33.6%) were female. (2) Study population were divided into four groups based on the 24-hour mean SBP, daytime mean SBP, night time mean SBP (group 1: mean SBP<120 mmHg, group 2: 120≤mean SBP<140 mmHg, group 3: 140≤mean SBP<160 mmHg, group 4: mean SBP≥160 mmHg), respectively. Values of SD, MMD and ARV, but not VIM were increased with increased mean SBP. (3) The participants were grouped according to the median SBPV with between-group comparison of the eGFR. The average eGFR levels were lower in the high 24-hour SB⁃ PV group (SD, VIM, MMD and ARV), day-time SBPV group (SD, VIM, MMD and ARV) and night-time SBPV group (SD, MMD and ARV) than those in the low SBPV groups (P < 0.05). (4) Multivariate stepwise linear regression showed that eGFR increased with 3 indices of 24-hour SBPV (SD, MMD and ARV) and 2 indices of day-time SBPV (MMD and ARV) but not for night-time SBPV (β=-0.07, -0.11, -0.07, -0.12 and -0.07, respectively). Conclusion There is a certain degree of asso⁃ ciation between short -term SBPV indices and eGFR.
