Clinical, Behavioral, and Sociodemographic Factors Associated With Self-Reported High Blood Pressure Among Canadian Adults: A Cross-Sectional Analysis of the 2022 Canadian Community Health Survey

BackgroundHypertension is a common cardiovascular risk factor in Canada.Its distribution may vary according to clinical, behavioural, and sociodemographic characteristics.Although Canadian studies have examined selected hypertension risk factors, contemporary national analyses that assess these domains together among adults remain limited. ObjectiveThe study aimed to identify clinical, behavioral, and sociodemographic factors associated with self-reported high blood pressure among Canadian adults. MethodsThis cross-sectional study used the 2022 Canadian Community Health Survey public use microdata file.Adults aged 18 years or older with complete data were included.Survey-weighted logistic regression estimated adjusted odds ratios and 95% confidence intervals.Sampling weights and 1,000 bootstrap replicate weights accounted for the complex survey design. ResultsThe analytic sample included 52,735 adults, representing 27,062,726 Canadian adults.Self-reported high blood pressure was reported by 5,458,778 (20.2% ) adults.Compared with adults aged 18 to 34 years, adults aged 65 years or older had markedly higher odds of self-reported high blood pressure -adjusted odds ratio: 27.24, 95% confidence interval: 22.00 to 33.73, p < 0.001.Overweight or obesity -adjusted odds ratio: 2.18, 95% confidence interval: 1.99 to 2.39, p < 0.001; diabetes -adjusted odds ratio: 2.49, 95% confidence interval: 2.21 to 2.81, p < 0.001; and fair or poor self-perceived health -adjusted odds ratio: 2.56, 95% confidence interval: 2.28 to 2.87, p < 0.001, were associated with higher odds.Female sex was associated with lower odds than male sex -adjusted odds ratio: 0.88, 95% confidence interval: 0.81 to 0.95, p = 0.001. ConclusionsSelf-reported high blood pressure was associated with age, sex, body mass index category, diabetes, selfperceived health, income, and province group.These findings may assist population health planning and support risk-based blood pressure assessment.Longitudinal studies using measured blood pressure and additional behavioural and clinical variables are needed.
