Impact of dietary and lifestyle factors on the prevalence of hypertension in Western populations

Q: What is the clinical evidence from this study?

Study design: Meta-Analysis. Population: Hypertension. Intervention: Dietary and lifestyle factors (overweight, physical inactivity, high sodium, low potassium). Primary outcome: Population attributable risk percentages (PAR%) for hypertension (systolic BP ≥140 mmHg).

Key result

Being overweight (PAR% 11-25%), physical inactivity (5-13%), high sodium intake (9-17%), and low potassium intake (4-17%) were the largest contributors to hypertension in Western populations.

May guide prevention priorities; leaves open causal effects pending randomized trials.

Key Points

This study aims to quantify the impact of dietary and lifestyle factors on hypertension prevalence across Western countries.
Analyzed blood pressure distributions and risk factors using nationwide surveys from Finland, Italy, the Netherlands, United Kingdom, and USA.
Utilized meta-regression analysis from randomized trials published between 1966 and March 2001.
Calculated population attributable risk percentages (PAR%) for key risk factors contributing to hypertension.
Being overweight contributes 11% to 25% to hypertension prevalence across countries.
Physical inactivity shows a PAR% of 5-13%, while high sodium intake ranges from 9-17%.
Low potassium intake contributes 4-17%, and low magnesium intake accounts for 4-8% of hypertension risk.

What is the population attributable risk of dietary and lifestyle factors for hypertension in Western populations?

Population

Populations from five Western countries assessed to quantify the contributions of body weight, physical inactivity, and dietary factors to the prevalence of hypertension.

Exposure

Dietary and lifestyle factors (body weight, physical inactivity, sodium, potassium, magnesium, alcohol, calcium, coffee, fish fatty acids)

Outcome

Population attributable risk percentages (PAR%) for hypertension (systolic BP >= 140 mmHg)surrogate

Diet and lifestyle, particularly overweight, high sodium, physical inactivity, and low potassium, substantially contribute to the prevalence of hypertension in Western societies.

Johanna M. Geleijnse (2004) conducted a meta-analysis in Hypertension. Dietary and lifestyle factors (overweight, physical inactivity, high sodium, low potassium) was evaluated on Population attributable risk percentages (PAR%) for hypertension (systolic BP ≥140 mmHg). Being overweight (PAR% 11-25%), physical inactivity (5-13%), high sodium intake (9-17%), and low potassium intake (4-17%) were the largest contributors to hypertension in Western populations.
