Reliability and validity of a questionnaire of child development for national surveys. / Confiabilidad y validez de un cuestionario de desarrollo infantil en encuestas nacionales.

INTRODUCTION: The child development screening in national surveys supports the formulation of public policies that contribute to its diagnosis and early intervention, aimed at promoting comprehensive development and successful school performance until adolescence, however, few countries in Latin America have this information. OBJECTIVE: To assess the reliability and convergent validity of a cultural adaptation of the Screening Questionnaire of Child Development for Household Surveys (DIEH) and to des cribe the prevalence of developmental alterations in children aged between 2 months and 5 years in Bucaramanga-Colombia. SUBJECTS AND METHOD: Between July and December 2016, an evaluation of diagnostic tests was carried out in which participated 224 children aged between two months and five years and their parents or caregivers from Bucaramanga, Colombia. The Abbreviated Developmental Scale was applied by trained physiotherapists and the DIEH was answered by the parents or caregi vers. The reliability of the DIEH was established using the Cronbach's alpha, the Intraclass Correla tion Coefficient (ICC) and the Bland and Altman limits of agreement, and the convergent validity was established through the Spearman Correlation Coefficient. RESULTS: Based on the DIEH, the pre valence of lags and delays was 38.8% and 11.2% respectively, internal consistency ranged from 0.23 to 0.76; reproducibility showed an ICC between 0.60 and 0.92; and the convergent validity was almost perfect (p: 0.96). CONCLUSION: The cultural adaptation of the DIEH showed acceptable psychometric properties, which could be complemented with additional studies to recommend its use in national surveys in Latin America.

Confiabilidad y validez de un cuestionario de desarrollo infantil en encuestas nacionales / Reliability and validity of a questionnaire of child development for national surveys

Resumen: Introducción: El tamizaje del desarrollo infantil en encuestas nacionales es un insumo para la formulación de po líticas públicas que contribuyan a su diagnóstico e intervención precoz, dirigidos a favorecer un de sarrollo integral y desempeño escolar exitoso hasta la adolescencia, no obstante, pocos países en La tinoamérica cuentan con esta información. Objetivo: Evaluar la confiabilidad y validez convergente de una adaptación cultural del Cuestionario de Tamizaje de Desarrollo Infantil para Encuestas en Hogares (DIEH) y describir la prevalencia de alteraciones en el desarrollo en niños de 2 meses a 5 años en Bucaramanga-Colombia. Sujetos y Método: Se realizó una evaluación de pruebas diagnósti cas. Participaron 224 niños de dos meses hasta los cinco años y sus padres o cuidadores procedentes de Bucaramanga - Colombia, entre julio y diciembre de 2016. La Escala Abreviada del Desarrollo (EAD) fue aplicada por fisioterapeutas entrenados y el DIEH, fue respondido por los padres o cui dadores. A partir del alpha de Cronbach, el Coeficiente de Correlación Intraclase (CCI) y los límites de acuerdo Bland y Altman se estableció la confiabilidad del DIEH; con el Coeficiente de Correlación de Spearman la validez convergente. Resultados: A partir del DIEH las prevalencias de rezagos y retrasos fueron 38.8% y 11.2% respectivamente; la consistencia interna osciló entre 0.23 y 0.76. La reproducibilidad registró CCI entre 0.60 y 0.92; la validez convergente fue casi perfecta (p: 0.96). Conclusiones: La adaptación cultural del DIEH mostró propiedades psicométricas aceptables, que podrían complementarse con estudios adicionales para recomendar su uso en encuestas nacionales en Latinoamérica.

INTRODUCTION: The development of motor skills influences the capacity of the child to interact with the environment. Thus, several instruments have been created for their assessment. OBJECTIVE: To evaluate the internal consistency, reproducibility, and agreement level of age band 1 of the Movement Assessment Battery for Children - 2 in a preschool group. PATIENTS AND METHOD: Assessment study of diagnostic tests with 29 preschoolers, selected by convenience, enrollments in an educational ins titution in Bucaramanga city, Colombia. For the inter-evaluators reproducibility assessment, three evaluators watched each video independently. In the intra-evaluator reproducibility assessment, each evaluator watched the same video on two different occasions. The internal consistency, the intra- and inter-evaluator reproducibility, and the agreement level were determined using Cronbach's alpha co efficient, the Intraclass Correlation Coefficient (ICC), and the Bland and Altman limits of agreement method, respectively. RESULTS: Internal consistency of the total test for each of the three evaluators was higher than 0.60. Very good reliability was found for all items, domains, and total score of age band 1 of MABC-2 (ICC > 0.85), as well as good limits of agreement. CONCLUSIONS: age band 1 of MABC-2 Spanish version is an instrument with adequate reliability psychometric properties that can be used for the motor skills development evaluation in preschoolers.

Prevalencia y factores asociados con el dolor de espalda y cuello en estudiantes universitarios / Prevalence and factors associated with back pain and neck pain in university students

El dolor de espalda es un problema de salud pública dada su prevalencia a lo largo de la vida, los altos costos para los sistemas de salud y la afectación en la calidad de vida de las personas. La alta prevalencia en estudiantes universitarios (30-70%), se relaciona con limitación funcional en las actividades de la vida diaria. Los factores intrínsecos y extrínsecos tales como: la edad, género, práctica de actividad física y tiempo en el computador están asociados con el dolor de cuello y espalda. Los estudios revisados muestran asociación positiva y significativa entre edades superiores a 20 ó 21 años, con la probabilidad de presentar dolor lumbar. El género femenino, los años matriculados en la universidad y las horas/semana en el computador se asocian con dolor de espalda en varias localizaciones. Los resultados son controversiales para la asociación entre la práctica de la actividad física y el dolor de espalda. La práctica de algunos deportes, así como la suspensión de la actividad deportiva aumentan la probabilidad de presentar dolor lumbar. Adicionalmente, los factores psicológicos deben ser considerados para comprender el problema del dolor en cuello y espalda. En universitarios se han realizado pocos estudios sobre la asociación de la postura sedente con el dolor de espalda, pero para la población en general se han descrito los aspectos biomecánicos relacionados con la alineación corporal y la activación muscular; la postura y la presión intradiscal; así como los factores ergonómicos y contextuales que afectan la adopción y el mantenimiento del sentado.

The back pain is a public health problem due to lifetime prevalence that increases the health system costs and affect of the quality of life of people. In university students high prevalence rates between 30-70% is related to functional limitation in activities of daily living. Intrinsic and extrinsic factors such as age, gender, physical activity practice and time spent using a computer are associated to neck and lumbar pain. The studies reported positive and significant association between the ages older than 20 or 21 years with lumbar pain. The female gender, academic years and hours per week in computer were associated to back pain in several locations. Conflicting evidence was found for the association between physical activity and back pain. The practice of some sports as well as suspend sport practice is associated with an increased risk of lumbar pain. Additionally, psychological factors should be considered also to understand the problem of neck and back pain. In university students, research on association between sitting and back pain are few, but in general population have been described the biomechanical aspects related to body alignment, muscle activation, the relationship between posture and intradiscal pressure, as well as ergonomic factors and contextual factors affecting the adoption and maintenance of the sitting.
