Introduction: Studies have identified high serum homocysteine ( Hcy) and cysteine ( Cys) levels as risk factor for cardiovascular diseases, important cause of death in all world. The factors associated with high levels of these biochemistry markers in adults are well known
however, data are sparse on these associations in the pediatric age group. Objective: the objective was to identify factors associated with different concentrations of serum Hcy and Cys in children and adolescents. Methods: a cross-sectional study with 483 individuals of 715 years of age of both sexes, from a municipality of Bahia. Serum Hcy and Cys levels were considered outcome variables, with exposure being evaluated according to sociodemographic, clinical, biochemical and lifestyle variables. Polytomous logistic regression was used to evaluate the association between exposure and outcome. Results: high serum Hcy levels were associated with being male (PR=3.74
p<0.01), age =12 years (PR=2.56
p<0.01), being overweight (PR=2.32
p=0.02), high blood pressure (PR=1.97
p<0.01), low HDL-c levels (PR=1.21
p=0.03), high triglyceride levels (PR=1.62
p=0.03) and poor intake of foods that protect against hyperhomocysteinemia (PR=1.46
p=0.02). High serum Cys levels were associated with age =12 years (PR=2.1
p=0.03), being overweight (PR=2.52
p=0.03)
high blood pressure (PR=1.28
p=0.03), low HDL-c levels (PR=1.15
p=0.01), high triglyceride levels (PR=1.41
p=0.02) and poor intake of foods that protect against hyper-cysteinemia (PR=1.46
p=0.01). Conclusions: age > 12 years, being overweight, high blood pressure, low HDL-c levels, high triglyceride levels and poor intake of protective foods are common factors found in individuals with increased serum Hcy and Cys levels. Being male was associated with high serum Hcy levels alone. Considering that these factors are already present early in life, measures should be adopted to prevent and control high Hcy and Cys levels, promoting health and preventing chronic non-communicable diseases at this stage of life.
