Key result
A high triglyceride-glucose index was significantly inversely correlated with multiple pulmonary function metrics, including FEV1% predicted and FEV1/FVC, suggesting an association with poorer lung function.
Why the study?
The relationship between the triglyceride-glucose index and pulmonary function metrics among the general population undergoing health examinations remained to be investigated.

A higher TyG index, a marker of insulin resistance, is independently associated with reduced lung function parameters in the general population.
TyG index was associated with reduced lung function; hypothesis-generating for metabolic-pulmonary links, needs prospective confirmation.
Purpose: To investigate the relationship between the triglyceride-glucose (TyG) index and pulmonary function metrics among the general population undergoing health examinations. Materials and Methods: The enrollment totaled 696 participants. Fasting triglycerides and glucose levels were used to calculate the TyG index. Participants were divided into two categories according to their median TyG: one with high TyG and the other with low TyG. A portable spirometer was used to assess lung function. Fundamental clinical features and lung function indicators were compared between the two groups, and the relationship between the TyG index and lung function parameters was explored. Results: Compared with the low TyG group, the high TyG group exhibited significantly reduced levels of FEV1/FVC, FVC% pred, FEV1% pred, FEV3% pred, FEV3/FVC, FEF75, FEF75% pred, FEF25-75% pred, and MVV% pred, suggesting poor pulmonary function. The TyG index was significantly inversely correlated with multiple pulmonary function metrics, including FVC% pred, FEV1% pred, FEV3% pred, FEV1/FVC, FEV3/FVC, FEF75, FEF75% pred and FEF25-75% pred, which persisted even after accounting for confounding variables. Conclusion: In summary, the present study establishes a correlation between the TyG index and some lung function indicators, offering a new indicator of metabolic abnormalities related to lung functionality.

Yang et al. (2024) conducted a cross-sectional in General population undergoing health examinations (n=696). High triglyceride-glucose (TyG) index vs. Low triglyceride-glucose (TyG) index was evaluated on FEV1% predicted (r = -0.1891, p=<0.0001). A high triglyceride-glucose index was significantly inversely correlated with multiple pulmonary function metrics, including FEV1% predicted and FEV1/FVC, suggesting an association with poorer lung function.
