The increase in the prevalence of metabolic disorders globally is becoming a public health concern. Previous studies have reported an association between environmental exposures to hazardous substances, including various heavy metals, and the risk for metabolic syndrome. However, reports on the contributions of cadmium (Cd) to the risk for obesity and diabetes remain inconsistent. This study aims to investigate an association between serum Cd levels (SCL) and diabesity and dyslipidemia risk scores. A total of 140 subjects were identified from a public academic institution in Lebanon. Socio-demographic information, diabesity, and obesity risk scores were determined using an interview-based adapted FINDRISC questionnaire and analysis of an acquired blood sample. SCL was quantified using inductively coupled plasma mass spectrometry (ICP-MS). The statistical analysis relied on a chi-squared test and multivariate logistic regression models, along with checks for confounders and effect modifiers. Our results showed a Cd geometric mean of 4.04 μg/L (± 2.5). High SCL was significantly associated with higher dyslipidemia risk (OR: 3.05 [95% CI: 1.19-7.86], P = 0.02), even after adjusting for confounders. However, SCL did not show a statistically significant association with diabetes and obesity outcomes. Elevated SCL increases the risk of dyslipidemia and alters the blood lipid profile. In addition, our findings do not support a role for Cd in diabesity.
