Capacity of Objective Measures of Physical Activity to Predict Brazilian Children's Low Motor Proficiency.

This study analyzed the associations between physical activity (PA) and motor proficiency (MP) to determine what level of moderate PA might help avoid low MP in 8-10-year-old Brazilian children. We assessed MP of 98 children using the Bruininks-Oseretsky Motor Proficiency, Second Edition Short Form (BOT-2 SF), and we assessed PA using the GT3X + accelerometer. We analyzed data using means, standard deviations, frequency distribution, spearman correlation coefficients, Mann-Whitney U test, and the Receiver Operating Characteristics curve.

The authors collected information on the perception of body weight (dependent variable), weight control behaviors (initiative to change the weight, physical exercise, eating less or cutting calories, fasting for 24h, taking medications, vomiting, or taking laxatives), and measured body weight and height to calculate the body mass index and then classify the weight status.

Receiver Operating Characteristic Curve Analysis of Screening Tools for Bipolar Disorder Comorbid With ADHD in Schoolchildren.

We compared Child Behavior Checklist (CBCL)-AAA (Attention Problems, Aggressive Behavior, and Anxious/Depressed) and Parent-Young Mania Rating Scale (P-YMRS) profiles in Brazilian children with ADHD, pediatric-onset bipolar disorder (PBD), and PBD + ADHD. Following analyses of variance or Kruskal-Wallis tests with multiple-comparison Least Significant Difference (LSD) or Dunn's Tests, thresholds were determined by Mann-Whitney Tests and receiver operating characteristic (ROC) plots. Relative to ADHD, PBD and PBD + ADHD groups scored higher on the Anxious/Depressed, Thought Problems, Rule-Breaking, and Aggressive Behavior subscales and Conduct/Delinquency Diagnostic Scale of the CBCL; all three had similar attention problems.
