This study investigated the associations between the chemical compound 1,3-butadiene (BD) exposure and glucose dyshomeostasis and diabetes in the general population. The results showed that BD exposure was positively associated with an increased risk of glucose dyshomeostasis, prediabetes, and diabetes, and serum alkaline phosphatase (ALP) mediated these associations.
The chemical - 1,3-butadiene (BD) is a volatile organic compound ubiquitous in the environment. However, the relationships and underlying mechanisms between BD exposure and glucose dyshomeostasis and diabetes in the general population remain unclear. We sought to explore the associations of BD exposure with glucose homeostasis, prediabetes, and diabetes, as well as the role of serum alkaline phosphatase (ALP) in these associations. This study included 5092 US general residents from the National Health and Nutrition Examination Survey with measurements of urinary BD metabolite (N-Acetyl-S-(3,4-dihydroxybutyl)-L-cysteine, DHBMA) and serum ALP. Glucose homeostasis was evaluated by fasting plasma glucose (FPG), fasting serum insulin (FINS), glycohemoglobin (HbA1c), and homeostasis model assessment of insulin resistance (HOMA-IR). HOMA-IR>2.6 was considered as insulin resistance (IR). Prediabetes and diabetes were determined according to the recommendations of the American Diabetes Association. The associations of DHBMA with glucose homeostasis, prediabetes, and diabetes were assessed by linear regression models and logistic regression models. The mediating role of ALP was evaluated by mediation analysis. We observed positive dose-response relationships of DHBMA level with glucose homeostasis indices and ALP levels, as well as with the risks of prediabetes and diabetes (all P < 0.05 and/or P for trend <0.05). Each 2-fold increase in DHBMA was associated with a 1.32%, 9.20%, 0.72%, and 10.64% increase in FPG, FINS, HbA1c, and HOMA-IR, respectively (all P < 0.05). And the corresponding odds ratios (ORs) and 95% confidence intervals (CIs) for IR, prediabetes, and diabetes were 1.36 (1.14, 1.61), 1.51 (1.26, 1.83), and 1.20 (0.90, 1.61), respectively. Furthermore, increased ALP significantly mediated 15.29%- 41.12% of the associations of DHBMA with glucose dyshomeostasis and increased risks of prediabetes and diabetes. Our findings indicated that BD exposure was associated with glucose dyshomeostasis and increased risks of prediabetes and diabetes. The upregulation of ALP might play a significant role in these associations.
