Hypothetical interventions and risk of atrial fibrillation by sex and education: application of the parametric g-formula in the Tromsø Study

Eur J Prev CardiolPublished Prospective population-based cohort study

Authors' conclusion

The population burden of AF could be reduced by modifying lifestyle risk factors.

Study context

Population
Women and men from the population-based Tromsø Study, Norway, 1994–2016
Participants
14,923 women
Exposure
Hypothetical interventions on six modifiable risk factors vs no intervention
Outcome
Long-term risk of AF under hypothetical interventions on smoking, physical activity, alcohol intake, BMI, SBP and DBP
Follow-up
Maximum of 22 years
Methodological detailsparametric g-formula, hypothetical interventions
  • Parametric g-formula
  • Hypothetical interventions

Main finding

As reported in the abstract

Cumulative AF risk · maximum 22 years

Risk reduction

41%

95% CI 17%–61%

Women

Risk reduction

14%

95% CI −7% to 30%

Men

Observational data: associations, not effects.

Further findings

Atrial fibrillation (AF) risk with BMI lowered to ≤ 25 kg/m² (most effective single intervention)

Lower risk (CI)
Women16% (4%–25%)
Men14% (6%–23%)
OutcomeEstimate
AF risk with sufficient physical activityWomenlower risk 7% (CI −4% to 18%)
AF risk with sufficient physical activityMenincreased risk 8% (CI −2% to −13%)

AF risk with sufficient physical activity

Significant sex-differences in relative risk reduction

Risk reduction by education level

No association between education level and differences in risk reduction by any intervention
