None of the equations had good agreement with bioimpedance analysis. CONCLUSION It was concluded that skinfold thickness and bioimpedance analysis should not be used interchangeably in children and adolescents. OBJECTIVES To develop and validate an instrument about nutritional knowledge and feeding practices to be used in children aged 7-11 years, based on the latest Brazilian Food Guide. METHODS Review on the subject; instrument creation; content validity with two groups of judges first, nutritionists and, after adjustments, a multidisciplinary group (content validity index [CVI]); FACE validity; reproducibility analysis (intraclass correlation coefficient [ICC], level of agreement, and kappa [k]); internal consistency analysis (Cronbach’s alpha[α]) and construct validity (Kaiser-Meyer-Olkin and exploratory factorial analysis). The sample was calculated, considering at least ten subjects for each question of the questionnaire. RESULTS There was a final sample of 453 children (53.6% girls), with a mean age of 9.45 years (SD = 1.44). The content validity showed a CVI ≥ 0.80 for relevance in 62.3% of the items for nutritionists’ group and 100% of the items for the multidisciplinary group, clarity (49.4%, 91.8%), and pertinence (58.8%, 98.4%), respectively. The test-retest showed a level of agreement of 84.3% and k = 0.740 for the Knowledge dimension and ICC = 0.754 for the Food Practices dimension. The internal consistency showed α = 0.589 for the Knowledge dimension and α = 0.618 for the Food Practices dimension. For the construct validity, Kaiser-Meyer-Olkin was 0.724 and exploratory factorial analysis showed a variance of 47.01 with varimax rotation and defined five factors for the Practices Dimension. CONCLUSION The Food Knowledge and Practices Questionnaire (Questionário de Conhecimento e Práticas Alimentares [QCPA]) instrument showed validity and reliability to assess nutritional knowledge and food practices in children aged 7-11 years. OBJECTIVE The aims of this study were twofold. First, to provide evidence of the validity and reliability of the Adolescent Lifestyle Profile-Revised 2 (ALP-R2) among adolescents in Chile; and second, to examine the relationship between the health-promoting behaviors measured by this scale and several demographic variables. METHODS Cross-sectional survey. Students attending grades nine through 12 from schools representing low-, middle-, and high-income families were included. All schools were in the city of San Felipe, Chile. Students completed the ALP-R2, a 44-item scale aiming to assess health-promoting behaviors. To evaluate validity and reliability, confirmatory factor analysis and omega coefficient calculation were conducted, respectively. RESULTS The sample size was 572 students (82.5% of the eligible population). More males (56.6%) than females (43.4%) participated in the study, and the mean age was 16.4 (SD, 1.3) years. The APL-R2 had adequate adjustment indicators in the confirmatory factor analysis, which means that the data supports the original theoretical model (seven subscales). The highest internal consistency was obtained for the total scale (Ω = 0.87); and (among the subscales), physical activity (Ω = 0.85) and spiritual health (Ω = 0.78) had the highest reliability. CONCLUSIONS The ALP-R2 appears to be a valid and reliable instrument to assess health-promoting behaviors among adolescents attending secondary schools. OBJECTIVE To evaluate the orofacial characteristics of very low-birth-weight preterm infants through anthropometric facial measures, orofacial anteroposterior analysis and the relationship between the gum pads. METHOD Orofacial examinations was performed in 154 infants, classified into two groups Group A comprised 54 very low-birth-weight infants who were examined after clinical stabilization and before hospital discharge, and Group B comprised 100 full-term infants. RESULTS The average anthropometricmeasurements in millimetres for Group A and Group B were as follows upper third30.2 and 31.1; middle third 24.2 and 25.9; lower third 27.6 and 29.9; facial width 64.8and 81.4. IWP-4 Regarding the orofacial anteroposterior analysis, the results showed that in99% of these infants, the mandible was in a retrognathic position relative to the maxilla.Group A and Group B had the following distributions of the relationship between thegum pads overbite-overjet 43% and 77%; overjet 39% and 17%; open bite 15% and3%; end-to-end 2% and 1%; overbite both 2%. CONCLUSION The very low-birth-weight preterm infants showed the upper third with the highest values in the facialharmony analysis, followed by the lower third and the middle third; and exhibited themandible in a retrognathic position relative to the maxilla, and with overbite-overjet themost prevalent type of gum pad relationship. The study emphasizes the importance of orofacial examination during neonatal hospitalization and the investigation of birth weight and gestational age in a multidisciplinary therapeutic approach that includes orofacial neonatal evaluation and actions that promote oral health, besides foster follow-up studies. Silymarin is a phytotherapeutic agent derived from the species Silybum marianum (Asteraceae), commonly is known as milk thistle, and traditionally used as a hepatoprotective; however, recent studies have proposed its use in order to promote lactogenesis, but there are few reports of its effects on the development of offspring. Thus, the objective of this study was to evaluate the effect of silymarin treatment during pregnancy and breastfeeding on the sensory-somatic-motor development and adult behavior of F1-generation Swiss mice. The pregnant females of the parental generation were distributed in four experimental groups and treated orally with doses of 100, 200 or 300 mg/kg of silymarin, with a control group receiving vehicle – vegetable oil (VEH), to obtain the F1-generation. At the end of lactation, the parental generation were submitted to euthanasia. Body mass evolution was determined in both generations. The sensory-motor development of the offspring (F1-generation) was evaluated, and one male pup from each litter was followed up for an analysis of adult behavior.
