Blood Lead Level in a Paediatric Population of South-Eastern Spain and Associated Risk Factors.

Objective: To determine blood lead levels (BLL) in a healthy paediatric population and to analyse related sociodemographic, dietary and haematological factors.

Methods: A cross-sectional study was made of 1427 healthy subjects aged 1-16 years from the city of Almería (south-eastern Spain). BLL, iron parameters and erythropoietin were determined, and sociodemographic and dietary data obtained.

Reference values of serum transferrin receptor (sTfR) and sTfR/log ferritin index in healthy children.

ABSTARCT The aims of this study were to determine appropriate reference ranges for serum transferrin receptor (sTfR) and sTfR/log ferritin (sTfR-F index) in healthy children and their relationship with iron parameters, erythropoiesis, and other conditions presented by the subject. A total of 902 children with normal iron status, aged 1-11 years, were included in a cross-sectional study. A physical examination was conducted and z-score of body mass index (zBMI) obtained.

Prevalence of overweight and obesity in children and adolescents aged 2-16 years.

Objectives: To estimate the prevalence of obesity and overweight in children and adolescents in our city and to investigate the associated factors.

Subjects And Methods: A cross-sectional study of 1317 children and adolescents aged 2-16 years. Multistage probability sampling was used to select three groups of subjects: 411 aged 12 to 16 years, 504 aged 6 to 12 years, and 402 aged 2 to 6 years.
