What is the clinical evidence from this study?

Study design: Cohort. Population: Metabolic syndrome (n=1757). Intervention: Resolution of youth metabolic syndrome vs. Persistent metabolic syndrome or never having metabolic syndrome. Primary outcome: High carotid intima-media thickness (IMT) and type 2 diabetes mellitus (T2DM) (RR 3.4 for high IMT, RR 12.2 for T2DM (persistent vs never MetS), 95% CI 2.4-4.9 for high IMT, 6.3-23.9 for T2DM, p=>0.20).

What question did this study set out to answer?

To examine whether the resolution of metabolic syndrome between youth and adulthood attenuates the risk of adult carotid artery intima-media thickness and type 2 diabetes mellitus.

Key result

Resolving youth MetS by adulthood is linked to cIMT and T2DM risk matching never-affected peers.

RR 3.4 for high IMT, RR 12.2 for T2DM (persistent vs never MetS)
95% CI 2.4-4.9 for high IMT, 6.3-23.9 for T2DM
P>0.20
n=1,757

Why the study?

Youth with metabolic syndrome are at increased risk of cardio-metabolic outcomes in adulthood, but whether this risk is attenuated if metabolic syndrome resolves is unknown.

Does the resolution of metabolic syndrome from youth to adulthood reduce the risk of high carotid intima-media thickness and type 2 diabetes?

Population

1,757 participants examined in youth (9 to 18 years of age)

Comparison

Resolution vs persistence of MetS status from youth to adulthood vs non-MetS

Design

Two prospective cohort studies

Follow-up

14 to 27 years

Implication

May support targeting youth metabolic syndrome resolution; observational data leaves open causal effects of intervention.

Key Points

To examine whether the resolution of metabolic syndrome between youth and adulthood attenuates the risk of adult carotid artery intima-media thickness and type 2 diabetes mellitus.
Prospective study evaluating 1,757 participants across 2 prospective cohorts first examined during youth (ages 9 to 18 years) and reassessed 14 to 27 years later in adulthood.
Youth metabolic syndrome was defined by the presence of any 3 adverse components (low HDL cholesterol, high triglycerides, elevated glucose, high blood pressure, or high BMI), and adulthood status was defined using harmonized metabolic syndrome criteria.
Participants were categorized by metabolic syndrome status transitions across time points and assessed for adult high carotid intima-media thickness and type 2 diabetes.
Participants with persistent metabolic syndrome in both youth and adulthood faced 3.4 times the risk of high carotid intima-media thickness (95% CI: 2.4 to 4.9) compared to those without the syndrome at either time point.
Persistent metabolic syndrome conferred 12.2 times the risk of type 2 diabetes mellitus in adulthood (95% CI: 6.3 to 23.9) relative to consistently syndrome-free individuals.
Individuals whose youth metabolic syndrome resolved before adulthood exhibited risks of high intima-media thickness and type 2 diabetes comparable to those who never developed metabolic syndrome (p > 0.20 for all comparisons).

Does the resolution of metabolic syndrome from youth to adulthood reduce the risk of high carotid intima-media thickness and type 2 diabetes?

Population

1,757 participants from 2 prospective cohort studies examined as youth (9 to 18 years of age)

Intervention

Resolution of metabolic syndrome (MetS) status by adulthood

Comparator

Persistent MetS in adulthood, and never having MetS at either time-point

Outcome

High carotid artery intima-media thickness (IMT) and type 2 diabetes mellitus (T2DM) in adulthoodsurrogate

Main Result

Effect estimate: RR 3.4 for high IMT, RR 12.2 for T2DM (persistent vs never MetS) (95% CI 2.4-4.9 for high IMT, 6.3-23.9 for T2DM)

p-value: p=>0.20

Resolution of metabolic syndrome from youth to adulthood normalizes the risk of high carotid intima-media thickness and type 2 diabetes to levels seen in individuals who never had metabolic syndrome.

Magnussen et al. (2012) conducted a cohort in Metabolic syndrome (n=1,757). Resolution of youth metabolic syndrome vs. Persistent metabolic syndrome or never having metabolic syndrome was evaluated on High carotid intima-media thickness (IMT) and type 2 diabetes mellitus (T2DM) (RR 3.4 for high IMT, RR 12.2 for T2DM (persistent vs never MetS), 95% CI 2.4-4.9 for high IMT, 6.3-23.9 for T2DM, p=>0.20). Resolution of youth metabolic syndrome by adulthood normalized the risk of high carotid intima-media thickness and type 2 diabetes to levels similar to those who never had the syndrome (p>0.20).
