To confirm factors associated with hypertension across the lifecourse among female twin pairs, focusing on unique female-specific aspects.
Key Findings:
Weighing ≥150lbs. at age 18 was associated with 3-fold odds of hypertension.
Weighing ≥180lbs. at the time of questionnaire was associated with 6-fold odds of hypertension.
Exercising more than one's co-twin was associated with 0.54-fold odds of hypertension.
Menopause was positively associated with hypertension, with postmenopausal dizygotic twins experiencing 4-fold odds compared to premenopausal co-twins.
Interpretation:
The study confirmed multiple factors associated with hypertension in women, including body weight at different life stages, exercise levels, and menopausal status.
Limitations:
Self-reported data may introduce bias, potentially affecting the reliability of the findings.
Genotype data was not available for verification of zygosity, which could limit the accuracy of twin classification.
Exclusion of certain twin pairs may limit generalizability to the broader population.
Conclusion:
The findings highlight the importance of considering unique female-specific factors in hypertension risk, suggesting potential areas for targeted interventions such as weight management and exercise programs tailored for women.
