Artigo The impact of essential and toxic elements on cardiometabolic risk factors in adults and older people(Journal of trace elements in medicine and biology, 2022) Lima, Severina Carla Vieira Cunha; Nunes, Francisca Leide da Silva; Lyra, Clélia de Oliveira; Marchioni, Dirce Maria; Pedrosa, Lucia Fatima Campos; Barbosa Júnior, Fernando Barbosa; Evangelista, Karine Cavalcanti Maurício Sena; https://orcid.org/0000-0001-8268-1986Background and aim Evidence suggests an association between essential and toxic elements and the worsening of cardiometabolic risk factors. This study aimed to investigate the concentrations of zinc, copper, selenium, arsenic, cadmium, and mercury and their relationship with cardiometabolic risk factors in adults and older people. Methods: This cross-sectional study was carried out with 112 adults with a mean age of 59 (sd 14) years old and a BMI of 29.30 (sd 5.11) Kg/m2. The subject’s weight and height were measured for body mass index (BMI) calculation, classified according to the cut-off points recommended by the World Health Organization (WHO). We evaluated sociodemographic, clinical, lifestyle, waist circumference – WC, visceral adiposity index - VAI, glycemic lipid profile, blood pressure, and high-sensitive C-reactive protein (hs-CRP). Cardiovascular risk was defined by The Global Risk Score (GRS) score. Plasma zinc, selenium, copper levels, urinary arsenic, cadmium, and mercury levels were measured using the inductively coupled plasma mass spectrometry technique (ICP-MS). Results: There was a negative association between urinary arsenic and VAI (β − 0.03, p < 0.01), triglycerides (β − 1.10, p < 0.01), and VLDL cholesterol (β − 0.14, p = 0.02). Plasma copper and copper/zinc ratio were positively associated with fasting glucose and hs-CRP (β 0.38, p < 0.01; β 36.02, p = 0.01, β 0.004, p < 0.01, β 0.68, p < 0.001, respectively). Urinary arsenic (β − 0.14, p = 0.04) and cadmium (β − 36.42, p = 0.04) were negatively associated with systolic blood pressure. Also, urinary cadmium was negatively associated with diastolic blood pressure (β − 21.55, p = 0.03), and urinary mercury showed an opposite behavior (β 1.45, p = 0.03). Conclusion: Essential and toxic elements in urine and plasma could be potential biomarkers for cardiovascular risk factors. A healthy lifestyle should be adopted; in addition, government policies should be developed to guarantee sustainable production and a safe environment.
