Description
Summary:•Young women are at risk of insulin resistance and obesity by environmental factors.•APOAV allele G correlates to hypertriglyceridemia, low HDL and metabolic syndrome.•ABCA1 allele A carriers show a high risk of obesity, low HDL and metabolic syndrome.•Carriers of allele T of GCKR show a greater high risk to high glucose.•Insulin resistance risk is correlated to the genetic variants when having BMI or HBF. Overweight/obesity, dyslipidemias, hypertension and hyperglycemia are strongly related to non-communicable diseases (NCD) in which genetic and environmental factors interact with each other. The Mexican population exhibit a genetic disposition to metabolic syndrome, type 2 diabetes, as well as many forms of dyslipidemia. This study aimed to determine the association between biochemical, genetic and environmental factors in the development of metabolic syndrome (MS), obesity and insulin resistance (IR) in Mexican young adults. Young women and men (n=6750 between 19.3±2.3 years old) participated in a health promotion program from the Autonomous University of Querétaro, México (SU-Salud program). A sub-sample of 665 participants was taken for the determination of single nucleotide polymorphisms (SNP) rs964184 (APOAV), rs9282541 (ABCA1) and rs1260326 (GCKR), using QuantStudio 12K Flex Real-Time PCR System. For the multivariate analysis, a multiple logistic regression was performed. A prevalence of 22% of overweight and 7% of obesity was determined. The main metabolic risk factors were low levels of HDL-C (30%), IR (19%), and a high level of triglycerides (15%). The main factors associated with IR were body fat percentage and triglycerides; SNP for the ABCA1 gene was related to MS, obesity and low HDL-C; SNP for GCKR gene was related to high fasting glycemia, while APOAV SNP was related with MS, hypertriglyceridemia and low HDL-C. Our findings show that the Mexican genetic predisposition to NCD affects young adults, who can suffer MS, obesity and IR. Public health strategies must focus on prevention actions from an early age.
