The relationship between anxiety and cardiometabolic risk factors in adolescents with obesity: propensity scores

It has been described that there is a relationship between metabolic health and anxiety.

To determine the relationship between anxiety and metabolic syndrome, as well as cardiometabolic risk factors, in adolescents with obesity.

We conducted a comparative cross-sectional study of adolescents with obesity between January 2019 and December 2022. In each patient, we recorded somatometric measurements, lipid profiles, and serum insulin levels. Anxiety was measured using the Spence Children's Anxiety Scale. Participants were divided into those with and without anxiety. Patients with anxiety were matched to patients without anxiety using propensity scores based on z-score body mass index (zBMI). Mann-Whitney U tests and χ² tests were used.

Of the 564 adolescents, 32.6% (n = 184) suffered from anxiety. In the overall study population, no differences in biochemical and cardiometabolic parameters were observed between the adolescents with and without anxiety prior to adjusting the groups based on zBMI. After matching using their zBMI, we found that the adolescents with anxiety had higher serum uric acid levels (5.9 mg/dl vs. 5.4 mg/dl, p = 0.041), an increased incidence of metabolic syndrome (39.1% vs. 15.9%, p = 0.002), hyperglycemia (21.7% vs. 8.6%, p = 0.020), and lower HDLc (67.3% vs. 34.7%, p < 0.001), than those without anxiety. Girls with anxiety had a higher proportion of cardiometabolic risk factors compared to those without anxiety.

Adolescents with obesity and anxiety had higher cardiometabolic risk factors than those without anxiety.
