OBJECTIVE To compare the most commonly used equations to predict body fatness from skinfold thickness, in male and female adolescents, with dual-energy X-ray absorptiometry (DXA) as a reference method of fatness measurement. DESIGN Cross-sectional nutrition survey. SETTING General adolescent population from Zaragoza (Spain). SUBJECTS AND METHODS A(More)
Newborns usually lose 5-10% of their initial weight during the first 4 days of life. Our aim, using bioelectrical impedance (BI), was to study the body composition of healthy term newborns and the nature of the changes which accompany this physiological weight loss. Forty-three healthy term newborns, all with adequate weight for their gestational age, were(More)
While the association of lean mass (LM) with bone mass is well understood, the association of fat mass (FM) with bone mass is controversial. Our results support that adolescents with higher levels of adiposity have greater bone mass, but this association is fully explained by their higher levels of LM. We aimed (1) to study the independent association of FM(More)
BACKGROUND Despite the widespread use of highly effective contraceptive methods in France, one in every three pregnancies is unintended. Among women experiencing an unintended pregnancy leading to an abortion, half had changed their contraceptive method in the 6 months preceding the abortion, in most cases switching to a less-effective method or to no(More)
We report a new case of encephalocraniocutaneous lipomatosis, a rare neurocutaneous syndrome of unknown etiology with involvement of tissues arising from the mesoderm and ectoderm: skin, eye, adipose tissue, and brain. We also review the neurologic manifestations of the syndrome, the most frequent of which include seizures, ventricular enlargement,(More)
An approach to a standardized analysis of menstrual bleeding patterns is presented. The method utilizes a prospective bleeding record and characterizes the menstrual pattern of a woman according to bleeding and nonbleeding events without imposing definitions of cycle or intermenstrual bleeding. Further, the analysis is done within a time reference period(More)
Lifestyle plays an important role in the development of obesity during childhood and adolescence. We provide up-to-date information about the relationship between obesity and food intake and dietary patterns in adolescents. Scientific evidence is increasing about the dietary factors associated with this relationship, specifically a low meal frequency,(More)
Obesity is the result of an imbalance between energy intake and energy expenditure. Controversial information exists about what are the strongest energy balance aspects influencing body fatness. This article is focused on food consumption facts that could be related to the risk of being obese in children and adolescents. It reviews whether energy intake,(More)
A systematic review to identify studies reporting the effects of n-3 long chain polyunsaturated fatty acids (LCPUFA) intake, during pregnancy and postnatally, on infants and young children's body composition was performed. A structured search strategy was performed in the MEDLINE (PubMed), EMBASE, and LILACS databases. Inclusion and exclusion criteria were(More)
OBJECTIVES This study aimed to explore the associations of liver biomarkers with cardiometabolic risk factors and their clustering, and to provide reference values (percentiles) and cut-off points for liver biomarkers associated with high cardiometabolic risk in European adolescents. METHODS Alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT),(More)
