Implication
Overweight substantially contributes to hypertension burden; extends cross-sectional associations but leaves causal effects and intervention benefits for prospective trials.
Key Points
- To determine the independent associations of obesity and alcohol intake with blood pressure levels and the prevalence of hypertension in adult men and women.
- Cross-sectional survey of 5,550 male and female participants aged 25 to 64 years from the 1980 National Heart Foundation of Australia Risk Factor Prevalence Study.
- Assessed independent relationships between body mass index, alcohol consumption, and blood pressure levels, including response to antihypertensive treatment.
- Body mass index was independently associated with blood pressure in both sexes, with up to 30% of overall hypertension—and up to 60% in men under 45 years—attributable to overweight.
- Alcohol consumption was independently linked to blood pressure in males (up to 11% attributable hypertension risk), whereas the trend in females (up to 1% attributable risk) did not reach statistical significance due to lower intake.
- Body mass index remained positively associated with blood pressure among treated individuals, with overweight hypertensive patients being significantly less likely to achieve normal blood pressure.

Obesity and alcohol consumption are significant, independent risk factors for elevated blood pressure and hypertension in adults.
