BACKGROUND: The aim of this study was to evaluate whether the mean and the variability of home blood pressure (HBP) from the logbook correlate with albuminuria as well as HBP from the stored memory in patients with type 2 diabetes.
METHODS: This study is a post hoc analysis of a cross-sectional multicenter study. HBP measurements were performed for 14 consecutive days in 276 patients with type 2 diabetes. Patients were requested to write down their HBP values in logbooks and were not informed about the memory function of their BP monitoring devices.
RESULTS: HBP values from the logbook were significantly lower and less variable than those from the stored memory. The mean of morning systolic BP (SBP) from the logbook (adjusted β = 0.326, P < 0.001) as well as that from the stored memory (adjusted β = 0.336, P < 0.0001) was significantly associated with logarithm of urinary albumin excretion (UAE). The SD of morning SBP (adjusted β = 0.134, P = 0.017) from the stored memory was significantly associated with logarithm of UAE, in contrast, the SD of morning SBP (adjusted β = 0.104, P = 0.057) from the logbook was not associated with logarithm of UAE.
CONCLUSIONS: Patients with type 2 diabetes might report inaccurate HBP measurements and, as a result, the variability of HBP from the logbook is underestimated and poorly correlates with albuminuria. The use of stored BP measurements is recommended to accurately evaluate the relationship with diabetic nephropathy.
