Key result
Obesity was associated with significantly higher QT-intervals compared to nonobese adults (P = 0.000).
Why the study?
Obesity causes cardiac morphology alterations or conduction defects reflected as ECG interval prolongations, and this study investigated the effect of obesity on QT-interval to assess early cardiovascular disease risk.
Does obesity prolong the QT-interval in young adults?
Population
80 cases and 80 controls aged 18–40 years of both sexes
Comparison
Obese (BMI >30 kg/m2) vs nonobese (BMI < 25 kg/m2)
Design
Cross-sectional study

QT prolongation in obese young adults may signal arrhythmia risk; cross-sectional data leave causality and practice implications open.

Does obesity prolong the QT-interval in young adults?
p-value: p=0.000
Obesity in young adults is associated with significant prolongation of the QT-interval, a surrogate marker for increased risk of ventricular arrhythmias.
Sakshi et al. (2019) conducted a cross-sectional in Obesity (n=160). Obesity vs. Nonobese was evaluated on QT-interval (p=0.000). Obesity was associated with significantly higher QT-intervals compared to nonobese adults (P = 0.000).
