Triglyceride Glucose-BMI may be used as indicator to monitor asthma prevalence: Study

The research highlighted that TyG-BMI was positively correlated with asthma prevalence as a continuous variable. For every unit increase in TyG-BMI, the odds of having asthma slightly increased (OR: 1.003). Dividing TyG-BMI into quartiles showed a significant stepwise increase in asthma risk. The highest quartile was associated with the most pronounced asthma prevalence.

The researchers emphasized that TyG-BMI could serve as an effective indicator for monitoring asthma risk. However, they cautioned that the cross-sectional nature of the study limits the ability to establish causality. Longitudinal studies are needed to confirm these findings and explore the biomarker’s utility in managing long-term comorbidities related to asthma and insulin resistance.

Asthma remains a significant public health burden by affecting millions and contributing to rising healthcare costs. The findings of this study illuminate the need for a comprehensive approach that considers metabolic health when addressing respiratory diseases. Health experts believe that incorporating metabolic markers like TyG-BMI into regular health assessments could improve early detection and targeted management strategies for individuals at risk of developing asthma.

Further research could pave the way for innovative treatment pathways that simultaneously address respiratory and metabolic health concerns. Overall, this research underlined the intricate links between metabolic health and respiratory conditions, encouraging both physicians and policymakers to explore new avenues for prevention and treatment.
