Distinct child-to-adult body mass index trajectories are associated with different levels of adult cardiometabolic risk

Eur Heart JPublished Prospective cohort study

Authors' conclusion

The long-term BMI trajectories that reach or persist at high levels associate with CVD risk factors in adulthood.

Study context

Population
Cardiovascular Risk in Young Finns Study participants followed from childhood to adulthood (6–49 years)
Participants
2,631 participants
Exposure
Child-to-adult body mass index (BMI) trajectories vs stable normal BMI
Outcome
Adult CVD risk factors: T2DM, high-risk lipid levels, hypertension, high cIMT
Follow-up
Adulthood (34-49 years)
Methodological detailslongitudinal, latent class growth mixture modelling

Main finding

As reported in the abstract

Adult CVD risk factors (T2DM, high-risk lipids, hypertension, high cIMT) by BMI trajectory · adulthood (24-49 years)

Relative risk

2.6

95% CI 0.14–8.23

Resolvingvs Stable normal
RR 2.6 (95% CI 0.14–8.23)
Worsening or persisting obesity trajectories vs stable normal: increased risk of adult cardiovascular disease (CVD) outcomes
all risk ratios (RRs) >15, P < 0.05
Resolving vs never obese or overweight: similar risk of dyslipidaemia and hypertension
all RRs close to 1
Resolving (elevated child BMI resolved) vs stable normal: significantly higher risk of increased carotid intima-media thickness (cIMT)
RR = 3.37, 95% CI = 1.80-6.39

Observational data: associations, not effects.
