[Current status of home blood pressure measurement and relevant demographics and lifestyle characteristics of individuals with periodic measurement: a cross-sectional study in a worksite population].

Objectives: The current status of home blood pressure (HBP) measurement is unknown at a Japanese worksite. We aimed to calculate the proportion of individuals who periodically measured HBP and to explore the demographic and lifestyle characteristics of these workers.

Methods: The study included 4,664 employees aged 40-65 years who worked at a retail company and underwent health check-ups in 2018. Multivariable logistic regression models were used to estimate odds ratios (ORs) of participant's demographics and lifestyle characteristics and habits for HBP measurement by sex and medical treatment for hypertension. Periodic HBP measurement was defined as HBP measurements performed two times or more per month (opportunistic HBP measurement) among participants not being treated for hypertension, and daily measurement of HBP (everyday HBP measurement) among participants treated for hypertension.

Results: The percentages of opportunistic HBP measurement were 8.7% in males and 12.4% in females not being treated for hypertension. In both sexes, age (ORs per 1-year increment: 1.11 in males and 1.06 in females) and blood pressure (ORs of ≥ 140/90 mmHg: 7.42 in males and 4.71 in females compared with < 130/80 mmHg) were positively associated with opportunistic HBP measurement. Females treated for dyslipidemia (OR: 1.77), who had a self-described fast walking speed (OR: 1.49), and who exercised habitually (OR: 1.79) had significantly high ORs for opportunistic HBP measurement. Females who frequently consumed snacks after dinner had significantly lower ORs (0.65) than those who did not. The percentages of workers who did everyday HBP measurement were 21.6% in males and 25.5% in females treated for hypertension. Males treated for diabetes (OR: 0.23) had significantly lower OR than those who did not. Females treated for dyslipidemia (OR was 0.53), who had uncontrolled hypertension (OR: 0.58), consumed alcohol (OR: 0.60), and frequently ate within two hours before bed (OR: 0.54) had significantly lower ORs. Females who lived alone had significantly higher ORs (2.43) than those who did not.

Conclusion: Approximately 10% of individuals not treated for hypertension periodically measured HBP. Age and blood pressure in males and females, and healthy lifestyles in females, were associated with having opportunistic HBP measurement. Approximately 25% of individuals treated for hypertension measured HBP every day. Individuals treated for dyslipidemia or diabetes and females with unhealthy lifestyle and uncontrolled hypertension were less likely to measure HBP every day.
