Key result
A school-based lifestyle intervention resulted in 22.0% of students meeting ideal cardiovascular health compared to 17.5% in the control group, and improved ideal health behaviors (OR 1.15).
Why the study?
The prevalence of ideal cardiovascular health among Chinese children and adolescents is alarmingly low, prompting an evaluation of whether a school-based lifestyle intervention against obesity would improve it.

Does a school-based lifestyle intervention improve ideal cardiovascular health in Chinese children and adolescents?
Absolute Event Rate: 22% vs 17.5%
A school-based lifestyle intervention focused on diet and exercise effectively improved ideal cardiovascular health behaviors in Chinese children and adolescents.
Guo et al. (2023) conducted an RCT in Low ideal cardiovascular health / Obesity (n=57,210). School-based lifestyle intervention vs. No promotion was evaluated on Ideal cardiovascular health (six or more ideal cardiovascular health behaviours and factors). A school-based lifestyle intervention resulted in 22.0% of students meeting ideal cardiovascular health compared to 17.5% in the control group, and improved ideal health behaviors (OR 1.15).
