Aim: Clinical evidence on cardiovascular health metrics of couples, as defined by the American Heart Association (AHA), remains to be scarce. This study aims to explore the correlation of the AHA-defined cardiovascular health metrics within couples using a nationwide epidemiological database.
Methods: We examined the modified cardiovascular health metrics among 87,160 heterosexual couples using the health claims database from the Japan Medical Data Center. The ideal cardiovascular health metrics is comprised of (1) nonsmoking, (2) body mass index ＜25 kg/m2, (3) physical activity at goal, (4) untreated blood pressure ＜120/80 mm Hg, (5) untreated fasting glucose ＜100 mg/dL, and (6) untreated total cholesterol ＜200 mg/dL.
Results: A correlation was noted on the ideal modified cardiovascular health metrics between couples. The prevalence of meeting ≥ 5 ideal components in the female partners increased from 32 % in the male partners meeting 0-1 ideal component to 56 % in those meeting 6 ideal components. The same trend has been observed in all generations (20-39 years, 40-49 years, 50-59 years, ≥ 60 years). The association between couples is found to be better in terms of smoking status, blood pressure, and fasting glucose level.
Conclusion: There was an intracouple correlation of the ideal modified cardiovascular health metrics, suggesting the importance of couple-based intervention to improve cardiovascular health status.
