Is hypertension more benign when associated with obesity?

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Obesity is a significant public health concern.
• Hypertension is a major risk factor for cardiovascular disease.
• The interplay between obesity, hypertension, and prognosis requires further investigation.

Purpose of the Study:

• To investigate the effect of obesity on the prognosis of hypertensive men.
• To determine if body mass index modifies the association between hypertension and mortality.

Main Methods:

• A cohort of 1727 men aged 50-79 was studied.
• Participants were categorized by body mass index (BMI) and systolic blood pressure (SBP).
• Mortality rates (all-cause, cardiovascular, ischemic heart disease) were assessed over a 9-year follow-up period using Cox regression.

Main Results:

• Nonobese hypertensive men exhibited higher age-adjusted mortality rates for all outcomes.
• Elevated SBP (≥160 mm Hg) significantly increased mortality risk only in nonobese subjects.
• The relative risk for ischemic heart disease mortality was highest in nonobese hypertensive individuals.

Conclusions:

• Prognosis appears poorer in leaner hypertensive patients compared to overweight hypertensive individuals.
• Systolic blood pressure is a significant predictor of mortality in nonobese hypertensive men.
• While not excluding adverse effects in obese individuals, leanness may confer a worse prognosis in hypertension.
