OBJECTIVE The goal of this study was to identify metabolites associated with metabolic risk, separately by sex, in Mexican adolescents. METHODS Untargeted metabolomic profiling was carried out on fasting serum of 238 youth aged 8 to 14 years, and metabolites associated with a metabolic syndrome risk z-score (MetRisk z-score) were identified separately for boys and girls, using the simulation ...
OBJECTIVE To assess whether growth and biomarkers of environmental enteric dysfunction in infancy are related to health outcomes in midchildhood in Tanzania. STUDY DESIGN Children who participated in 2 randomized trials of micronutrient supplements in infancy were followed up in midchildhood (4.6-9.8 years of age). Anthropometry was measured at age 6 and 52 weeks in both trials, and blood sam...
BACKGROUND Paediatric research analysing the relationship between the easy-to-use anthropometric measures for adiposity and cardiometabolic risk factors remains highly controversial in youth. Several studies suggest that only body mass index (BMI), a measure of relative weight, constitutes an accurate predictor, whereas others highlight the potential role of waist-to-hip ratio (WHR), waist circ...
We have shown that with our enhanced representation, the ranking problem for given weights w reduces to the one in Joachims (2005) in the case of a fully-factored model. Here we show a similar result for the learning problem. Recall that our learning objective is defined as: min w λ 2 w 2 + 1 M m max z∈Z w ϕ(x m , z) + ∆ AU C (z, y m) − maxˆz∈Zˆz∼y m w ϕ(x m , ˆ z) (1) We would like to consider...
background different clinical and epidemiological studies using dual-energy x-ray absorptiometry have shown an increased prevalence of low bone mineral density in patients with inflammatory bowel diseases.the aim of this study was to assess the correlation between bone density and the disease activity in patients with ulcerative colitis. methods in this cross-sectional study, 52 patients with u...
BACKGROUND Almost all presently available pediatric echocardiography Z-score nomograms are based on Western data. They may not be a suitable reference standard for assessing the sizes of cardiac structures of children from developing countries. OBJECTIVE This study's objective was to collect normative data of 21 commonly measured cardiovascular structures using M-mode and two-dimensional echo...
OBJECTIVE Psychological adversities among young children may be associated with childhood overweight and obesity. We examined if an increased level of child behavioural problems was associated with body size among a selected group of 2-6 year old children, who were all predisposed to develop overweight. METHODS Cross-sectional analyses were conducted using baseline data from the "Healthy Star...
