expert reaction to study of vascular function and cardiorespiratory fitness in young adults who vape
A new study in JAMA Cardiology examining vascular function and cardiovascular fitness among young adults who vape has drawn criticism from leading researchers over significant methodological limitations.
With just 17 vapers and 19 smokers included, experts warn that the findings cannot establish causation or demonstrate equivalent cardiovascular risks between vaping and smoking. Differences in participants’ smoking histories, physical activity and lifestyle factors further complicate interpretation.
The expert responses underline the importance of robust study design and accurate risk communication, particularly as stronger evidence suggests that switching completely from smoking to vaping can reduce cardiovascular harm.
11.80% of the adult population are current smokers. There are approximately 6.7 million current smokers in United Kingdom 13.60% of men are current smokers but only 10.10% of women.
