Effect of dietary counselling on educational disparities in cardiometabolic health from childhood to adulthood.

In 30 seconds

This randomized controlled study examined whether parental education was associated with cardiometabolic health from childhood to adulthood and whether it modified the effects of dietary counselling. Among 839 STRIP participants, 417 received individualized counselling for 20 years and 422 received routine care; outcomes were assessed repeatedly over 26 years. Higher parental education was associated with more favourable adult BMI (22.5 vs. 24.2 kg/m2), insulin resistance (HOMA-IR 1.6 vs. 1.8), and HDL cholesterol (1.4 vs. 1.3 mmol/L). Counselling effects did not consistently differ by education level.

Key findings

• Higher parental education was associated with lower adult BMI: 22.5 vs. 24.2 kg/m2 in high- versus low-education groups.
• Adult HOMA-IR was 1.6 vs. 1.8 and HDL cholesterol was 1.4 vs. 1.3 mmol/L in high- versus low-education groups.
• Higher parental education was associated with higher fibre and lower saturated fatty acid intake through adolescence and early adulthood.
• Education-by-intervention interactions were not consistent; interaction P-values were > 0.05 except for isolated findings in dietary cholesterol and systolic BP.

Why it matters

The findings indicate that cardiometabolic differences associated with parental education can persist into adulthood, while a long-term dietary counselling programme did not show consistent evidence of benefiting one educational group more than another. This distinction is relevant when interpreting population-level prevention: social disparities in health may remain even when an intervention’s measured effects do not clearly vary by educational background.

What to keep in mind

The abstract reports isolated education-by-intervention findings for dietary cholesterol and systolic BP, so the absence of consistent interactions does not establish identical effects across all outcomes.
