Key result
Evening chronotype associates with poorer CV health behaviors in children, explaining ~16% of variance.
Why the study?
Do chronotype characteristics affect cardiovascular health behaviors in school-age children?
Cross-Sectional
Do chronotype characteristics affect cardiovascular health behaviors in school-age children?
Effect estimate: 16% variance explained
p-value: p=< 0.01
Evening chronotype in school-age children is associated with poorer cardiovascular health behaviors, particularly an increased sedentary lifestyle.
Supports chronotype evaluation in pediatric cardiovascular assessments; leaves open causality and whether targeting it improves behaviors.
< 0.01), with the MESC explaining 16% of the variance in cardiovascular health behaviors. The MESC influenced cardiovascular health behaviors and its subscales nutrition, exercise, sedentary lifestyle, self-love, and stress subscales. Most school-age children display intermediate chronotype characteristics and cardiovascular health behaviors. Children with an evening chronotype demonstrated lower levels of cardiovascular health behaviors. Chronotype characteristics had the most negative impact on the sedentary lifestyle aspect of cardiovascular health behaviors. Furthermore, chronotype plays a significant role in explaining the key factors influencing cardiovascular health behaviors.

Altay et al. (2025) conducted a cross-sectional in Cardiovascular health behaviors. Chronotype characteristics was evaluated on Cardiovascular health behaviors (16% variance explained, p=< 0.01). Chronotype characteristics explained 16% of the variance in cardiovascular health behaviors in school-age children (P<0.01), with evening chronotypes demonstrating lower levels of these behaviors.
