Frailty, smoking history, lack of exercise predict HBPM cessation

In community-dwelling older adults, some factors that influence home blood pressure measurement (HBPM) include frailty, smoking history, female sex, and lack of exercise, among others.

Overall, 437 participants had available data for analysis, of whom 120 (27.5 percent) discontinued HBPM.

Univariate analysis revealed the following factors associated with HBPM discontinuation: exercise habits (hazard ratio [HR], 0.47, 95 percent confidence interval [CI], 0.31‒0.69), social participation (HR, 0.65, 95 percent CI, 0.42‒0.99), Montreal Cognitive Assessment (MoCA-J) score (HR, 0.94, 95 percent CI, 0.90‒0.98), and frailty (HR, 5.20, 95 percent CI, 2.87‒9.43).

In multivariate analysis, HBPM discontinuation was significantly associated with sex (HR, 0.55, 95 percent CI, 0.32‒0.95; female as reference), smoking history (HR, 1.69, 95 percent CI, 1.02‒2.80), exercise habits (HR, 0.51, 95 percent CI, 0.30‒0.85), MoCA-J score (HR, 0.93, 95 percent CI, 0.88‒0.98), and frailty (HR, 3.31, 95 percent CI, 1.50‒7.29).

This longitudinal analysis used datasets from the NOSE study intervention group. Participants were urged HBPM with self-monitoring devices twice in the morning and twice in the evening. Every 7-day interval from the HBPM initiation date was defined as 1 week. The researchers then counted the number of HBPMs per week.

HBPM discontinuation referred to the first week in which the number of HBPMs was zero. Participants who continued HBPM until the end of the observation period were considered complete survivors in the survival time analysis.
