Children's Eating Behaviour Questionnaire: associations with BMI in Portuguese children.

The objective of this study was to examine the association between the scores of the Children's Eating Behaviour Questionnaire (CEBQ) and BMI in a sample of Portuguese children. Using a cross-sectional design, a sample of 240 children (123 females and 117 males) aged 3-13 years were recruited from clinic and community-based settings. Parents completed the CEBQ to indicate their child's eating style for three 'food approach' and four 'food avoidant' sub-scales.

LDL peroxidation in adolescent female gymnasts.

Unlabelled: Physical exercise may in vivo promote an increase of free radical formation. Low-density lipoproteins (LDL) are highly susceptible to oxidation, probably because of their high polyunsaturated fatty acid content, since lipid oxidation is an important factor in the genesis and development of atherosclerosis. The aim of the present study is to evaluate the effect in a group of adolescent gymnasts, of intense and regular physical exercise on lipid profile and redox status.

Acid phosphatase, genetic polymorphism and cardiovascular risk factors in a pediatric population.

Background: Although the clinical expression of cardiovascular disease usually occurs in adulthood, it is unanimously accepted that atherosclerosis begins in the pediatric age. Because of the early onset of the disease, it is of great importance to screen for major risk factors since pre-school age, especially in risk families. Recent investigations have shown a great interest not only in studying the classic risk factors, but also in the evaluation of oxidative stress and the main antioxidant defense systems.
