Influential Periods in Longitudinal Clinical Cardiovascular Health Scores

Area of Science:

• Public Health
• Cardiology
• Epidemiology

Background:

• Ideal cardiovascular health (CVH) is uncommon in US adults and diminishes with age.
• Understanding age-related CVH decline is crucial for developing effective prevention strategies.

Purpose of the Study:

• To pinpoint specific age windows where CVH loss accelerates.
• To identify critical periods for cardiovascular health interventions.

Main Methods:

• Pooled data from 5 longitudinal cohorts (US & Finland, 1973-2012).
• Included individuals aged 8-55 with measured CVH factors (BMI, BP, cholesterol, glucose).
• Utilized segmented linear mixed models to analyze CVH score changes over time.

Main Results:

• Analyzed 18,343 participants (52% female, 67% White).
• Identified two significant inflection points for CVH decline: 16.9 years and 37.2 years.
• CVH loss accelerates in late adolescence and early middle age.

Conclusions:

• Late adolescence and early middle age are critical periods for accelerated CVH loss.
• Interventions during these age windows may significantly impact long-term cardiovascular health.
• Findings highlight the importance of age-specific cardiovascular health promotion.
