Triceps and subscapular skinfold thicknesses percentiles and cut-offs for overweight and obesity in a population-based sample of schoolchildren in Bogota, Colombia

OBJECTIVES: The aims of this study were to establish a Colombian smoothed centile charts and LMS tables for tríceps, subscapular and sum tríceps+subscapular skinfolds; appropriate cut-offs were selected using receiver operating characteristic analysis based in a populationbased sample of schoolchildren in Bogota, Colombia and to compare them with international studies. METHODS: A total of 9 618 children and adolescents attending public schools in Bogota, Colombia (55.7% girls; age range of 9–17.9 years). Height, weight, body mass index (BMI), waist circumference, triceps and subscapular skinfold measurements were obtained using standardized methods. We have calculated tríceps+subscapular skinfold (T+SS) sum. Smoothed percentile curves for triceps and subscapular skinfold thickness were derived by the LMS method. Receiver operating characteristics curve (ROC) analyses were used to evaluate the optimal cut-off point of tríceps, subscapular and sum tríceps+subscapular skinfolds for overweight and obesity based on the International Obesity Task Force (IOTF) definitions. Data were compared with international studies. RESULTS: Subscapular, triceps skinfolds and T+SS were significantly higher in girls than in boys (P <0.001). The median values for triceps, subscapular as well as T+SS skinfold thickness increased in a sex-specific pattern with age. The ROC analysis showed that subscapular, triceps skinfolds and T+SS have a high discrimination power in the identification of overweight and obesity in the sample population in this study. Based on the raw non-adjusted data, we found that Colombian boys and girls had high triceps and subscapular skinfolds values than their counterparts from Spain, UK, German and US. CONCLUSIONS: Our results provide sex- and age-specific normative reference standards for the triceps and subscapular skinfold thickness values in a large, population-based sample of 3 schoolchildren and adolescents from an Latin-American population. By providing LMS tables for Latin-American people based on Colombian reference data, we hope to provide quantitative tools for the study of obesity and its complications.

L'oeuvre des orphelins à l'Hospice du Sacré-Cœur de Sherbrooke (1875-1965)

L'industrialisation et l'urbanisation de la ville de Sherbrooke débutent au milieu du 19e siècle grâce à l'énergie hydraulique que fournit la rivière Magog et à l'implication de la British American Land Company. Diverses industries s'installent provoquant ainsi l'arrivée de Canadiens français et d'Irlandais en quête de travail. La population, d'abord anglophone et britannique, devient, dès 1871. majoritairement canadienne-française et elle se répartit dans quatre quartiers distincts. Les conditions de vie à Sherbrooke sont alors difficiles, car la promiscuité, le manque d'hygiène, la maladie et la criminalité sévissent. De plus, le chômage frappe assez fréquemment les familles ouvrières dont la vie est façonnée par les cycles économiques. L'insécurité financière dans laquelle elles vivent les oblige à réclamer l'assistance de leur parenté ou de la charité publique. Pour venir en aide à ces familles démunies, l'évêque fondateur du diocèse de Sherbrooke, Mgr Antoine Racine, réclame, dès 1674, la fondation d'une institution de charité. L'année suivante, l'Hospice du Sacré-Coeur ouvre ses portes, sous la direction des Soeurs de la Charité de Saint-Hyacinthe, pour secourir les malades, les vieillards et les orphelins. Dans le cadre de ce mémoire, nous avons limité nos recherches à l’oeuvre des orphelins de l'Hospice du Sacré-Coeur, laissant dans l'ombre les autres oeuvres de cette institution. Il nous apparaissait impossible d'étudier les deux principales catégories de bénéficiaires, les vieillards et les orphelins, car elles relèvent de circonstances et de phénomènes différents. L'Hospice du Sacré-Cœur n'a jamais fait l'objet d'une analyse historique, seules Louise Brunelle-Lavoie et Jovette Dufort-Caron lui ont consacré quelques pages dans leur livre sur l'Hôpital Saint-Vincent-de-Paul de Sherbrooke. Notre mémoire est donc consacré à un sujet jusqu'à présent inexploité par l'historiographie québécoise. Étant située au carrefour de l'histoire de l'enfance, de l'assistance sociale et de la famille, notre étude contribue à une meilleure connaissance de l'ensemble de la société québécoise. L'historiographie de la protection de l'enfance au Canada anglais est dominée par quatre auteurs : Neil Sutherland, Joy Parr, Patricia T. Rooke et Rodolph L. Schnell, le pionnier dans ce domaine. Neil Sutherland a publié en 1976 Children in English-Canadian Society; Framing the Twentieth-Century Consensus. Cet ouvrage présente les différentes réformes concernant la santé des enfants, le traitement des délinquants et l'éducation dans la communauté anglophone du Canada de 1870 à 1920. Sutherland estime que ces réformes témoignent de l'émergence d'une nouvelle conception de l'enfant à l'aube du 20e siècle. S'intéressant davantage au vécu des enfants qu'à l'organisation de l'assistance, Labouring Children; British immigrant Apprentices to Canada, 1869-1924 de Joy Parr, paru en 1980, retrace les conditions de vie des enfants démunis d'Angleterre qui ont été envoyés au Canada pour être mis en apprentissage chez des cultivateurs. Il faut aussi noter que plusieurs autres historiens et historiennes ont traité ce sujet mais d'une façon plus fragmentaire. En 1982, Childhood and Family in Canadien History, un ouvrage collectif sous la direction de Joy Parr, aborde les questions suivantes : l'enfance en Nouvelle-France, l'éducation en milieu rural, l'exil des jeunes néo-écossais, la (délinquance juvénile et le recours à l'orphelinat comme stratégie familiale en milieu ouvrier. On y retrouve, entre autres, un article de Bettina Bradbury dont nous reparlerons plus loin. Patricia Rooke et Rodolph L. Schnell travaillent en collaboration depuis plusieurs années. Ce sont, sans contredit, les auteurs les plus prolifiques en histoire de la protection de l'enfance. Ils ont étudié, dans quelques articles, les Protestant Orphan Homes, mais ils ne se sont jamais arrêtés sur les institutions catholiques. En 1982, ils ont publié Studies in Childhood History; A Canadien Perspective, un recueil d'articles, mais leur oeuvre majeur demeure Discarding the Asvlum: From Child Rescue to the Welfare State in English-Canada(1800-1950), paru un an plus tard. Fruit de cinq années de recherches, cette monographie retrace l'histoire de l'assistance institutionnelle de l'enfance, ses transformations et finalement son abandon comme méthode d'aide sociale [...].

Auditory lexical decisions in children with specific language impairment

This study examined spoken-word recognition in children with specific language impairment (SLI) and normally developing children matched separately for age and receptive language ability. Accuracy and reaction times on an auditory lexical decision task were compared. Children with SLI were less accurate than both control groups. Two subgroups of children with SLI, distinguished by performance accuracy only, were identified. One group performed within normal limits, while a second group was significantly less accurate. Children with SLI were not slower than the age-matched controls or language-matched controls. Further, the time taken to detect an auditory signal, make a decision, or initiate a verbal response did not account for the differences between the groups. The findings are interpreted as evidence for language-appropriate processing skills acting upon imprecise or underspecified stored representations.

Measurement of radiation dose received by the hands and thyroid of staff performing gridless fluoroscopic procedures in children

The aim of this study was to confirm that the radiation doses received by attendants who manually restrain infants during fluoroscopic procedures are low. Doses to the hands and neck of three radiologists and three nurses performing or assisting at all the fluoroscopic procedures in a children's hospital were measured for 1 month using thermoluminescent dosemeters. All fluoroscopy on children at this hospital is performed without an antiscatter grid. Total doses for the neck ranged from 20 to 50 mu Sv per week and for hands from 40 to 210 mu Sv per week. These doses were shared by the three radiologists and the three nurses. Individual doses received per staff member are very small when compared with the doses received by interventional radiology staff. Doses received by staff in this study were of the order of 5% of the limit advised by the National Health and Medical Research Council of Australia (NHMRC) for radiation workers. Nurses received larger doses than radiologists and steps will be taken to reduce this dose further.
