Implication

Obesity in pregnancy may warrant closer hypertension surveillance; leaves open whether interventions improve hemodynamics or outcomes.

Structured PICO

Does obesity during pregnancy increase the risk of hypertension and alter maternal hemodynamics compared to normal weight?

P
Population
2,115 pregnant women (1,160 primiparous, 955 multiparous) delivering singleton babies without life-threatening anomalies, selected based on BMI prior to the 10th gestational week. Excluded: chronic hypertension, overt diabetes mellitus, and extreme skinniness.
I
Intervention
Obesity (exposure)
C
Comparator
Normal-weight (control)
O
Outcome
Arterial blood pressure and incidence of pregnancy-induced hypertension

Obesity during pregnancy is associated with a significantly higher risk of pregnancy-induced hypertension, hemoconcentration, and impaired cardiac function.
