Aims: Recent nationwide in-depth analyses on inequalities in hypertension prevalence and care are scarce. This study assessed sociodemographic and lifestyle factors associated with the prevalence, awareness, treatment and control of hypertension in Finland. Methods: A representative nationwide sample (participation rate 58%) of the Finnish adult population underwent a health examination and interview in 2011. After excluding participants with missing data, 4230 people were included in the analyses. Weighted regression modelling was used to explore the associations of sociodemographic and lifestyle factors with the prevalence, awareness, treatment and control of hypertension. Results: The prevalence, awareness, treatment and control rates of hypertension (blood pressure 140/90 mmHg or antihypertensive medication) in Finland were 47%, 57%, 51% and 48%, respectively. Older age, male sex, lower education, retirement, higher BMI, never-smoking and heavy alcohol use were associated with a higher prevalence of hypertension (p<0.05). In contrast, younger age, non-retirement, lower BMI, smoking and high physical activity were associated with lower awareness and treatment rates (p<0.05). In addition, male sex was associated with lower awareness rates (p<0.01). Hypertension control was better in younger participants (p<0.05). Conclusions: In addition to high prevalence and moderate treatment rates of hypertension, serious sociodemographic and lifestyle inequities in hypertension care exist in Finland. Hypertension is more prevalent in older people of lower socio-economic status with adverse lifestyles. However, hypertension is more often unrecognised and untreated among people with low risk of hypertension.
