          Abstract

          La obesidad infantil en Chile ha sido reconocida como un problema de salud pública prioritario. En el año 2006 desarrollamos un proyecto piloto de intervención de 5 meses para prevenir obesidad en preescolares y escolares de pre-kinder a 4º grado en 7 escuelas públicas de una comuna de clase media-baja de Santiago de Chile. El objetivo del proyecto fue evaluar la factibilidad de implementar una intervención de más largo plazo y darle sugerencias a las autoridades para poder hacerlo en mejor forma. En las 7 escuelas se implementaron actividades educativas dirigidas a los niños, en los ámbitos de alimentación saludable y fomento de la actividad física, pero además en 4 de éstas, se implementó un programa para los profesores. Este consistió en Consejería personalizada en hábitos de vida saludable, evaluaciones antropométricas y bioquímica. Las iniciativas se evaluaron en una muestra de 522 escolares (estado nutricional y aptitud física) y en 38 profesores intervenidos (IMC, circunferencia de cintura, glicemia, HDL, colesterol total y triglicéridos) y los 19 sin intervención (IMC y circunferencia de cintura). Se determinó además la calidad de las clases de educación física. Los resultados muestran una tendencia en los escolares de menor edad de disminuir el % de obesidad, mejorando significativamente la aptitud física. En los profesores intervenidos se aprecia una tendencia a disminuir el IMC y circunferencia de cintura, mientras que los parámetros bioquímicos no variaron. Se muestra que es factible implementar un programa de más larga duración recomendando mejorar las clases de educación física y aumentar el tiempo disponible para Consejería y capacitación de profesores

          Childhood obesity in Chile has been recognized as a public health problem. In 2006, we developed a school-based obesity prevention pilot project to intervene during 5 months preschool and schoolchildren from 1st to 4th grades attending 7 public schools located in a district of Santiago, Chile of medium-low and low SES. The objective of this project was to evaluate the feasibility of implementing a longer intervention giving recommendations to the educational authorities to better implement it. We trained teachers to apply educational activities ( in nutrition and physical activity) for the children in the 7 schools, but additionally in 4 of these schools, teachers of those grades participated in a Counselling program on healthy lifestyle applied individually, anthropometric evaluation and blood tests. The initiatives were evaluated on a sample of 522 schoolchildren (nutritional status and physical fitness), 38 teachers with Counselling (BMI, waist circumference or WC, blood sugar, HDL, triglycerides, cholesterol) and 19 teachers with no Counselling (BMI and WC). Additionally, we evaluated the quality of PE classes. The results on the children show a trend on only the younger ones to decrease the % obesity, improving significantly their physical fitness. In teachers with Counselling, a trend toward decreasing BMI and WC was observed, while biochemical parameters remained unchanged. We showed that it is feasible to implement a longer intervention recommending improving the quality of PE classes and allowing more time to train teachers and for individual Counselling

          Six-minute walk test in children and adolescents.

          To evaluate the 6-minute walking distance (6MWD) for healthy Caucasian children and adolescents of a population-based sample from the age of 3 to 18 years. Two hundred and eighty boys and 248 girls completed a modified test, using a measuring wheel as incentive device. Median 6MWD increased from the age of 3 to 11 years in boys and girls alike and increased further with increasing age in boys (from 667.3 m to 727.6 m), whereas it essentially plateaued in girls (655.8 m to 660.9 m). After adjusting for age, height (P = .001 in boys and P < .001 in girls) remained independently correlated with the 6MWD. In the best fitting and most efficient linear and quadratic regression models, the variables age and height explained about 49% of the variability of the 6MWD in boys and 50% in girls. This modified 6-minute walk test (6MWT) proved to be safe, easy to perform, and highly acceptable to children. It provides a simple and inexpensive means to measure functional exercise capacity in children, even of young age, and might be of value when conducting comparable studies.

            Nutrition transition in Chile revisited: mid-term evaluation of obesity goals for the period 2000-2010.

            To analyse the nutritional status component of the nutrition transition in Chile in relation to the evolution of obesity rates in all age groups until 2005, comparing these with the goals established by the Ministry of Health for the period 2000-2010. A descriptive study which includes data on the nutritional status of the Chilean population categorised by age. The data originate from: (1) institutions which administer nutritional programmes - the National Board for Day-Care Centres (JUNJI) and the National Board for School Assistance and Scholarships (JUNAEB); (2) the Ministry of Health and the National Institute of Statistics; and (3) epidemiological studies which include adolescents and the elderly. The prevalence of obesity in pre-school children attending JUNJI was 10.6% in 2005; by age group, it was 6% in 2-year-olds, 11% in 3-year-olds and 14% in 4-year-olds. Among schoolchildren in first grade, obesity prevalence was 18.5%. In pregnant women, obesity has increased from 12% in 1987 to 33% in 2004. For adults, the 2003 National Health Survey showed that the prevalence of obesity (body mass index (BMI) > or = 30 kg m-2) was 22% and of morbid obesity (BMI > or = 40 kg m-2), 1.3%. Obesity varied according to gender and educational level, being higher among women (25% vs. 19% in men) and adults from low socio-economic levels. In the elderly there was a high prevalence of obesity in the 60-64 years age group for both men (35.6%) and women (44.1%), decreasing to 18% and 26%, respectively, in those aged 75 years and older. The goals for the decade (2000-2010) consider a reduction of obesity rates from 10% to 7% in pre-school children attending JUNJI, and from 16% to 12% in schoolchildren attending first grade. For pregnant women, the goal is to reduce the prevalence from 32% to 28%. Despite the implementation of initiatives in nutrition and physical activity, these have been insufficient to shift the rising trend in obesity. The explanation could be that after a rapid rise in obesity in children and pregnant women between 1987 and 2000, a stabilisation period or a 'plateau' is observed. In that situation, very effective interventions are required to reduce obesity, because it is extremely difficult to reverse the trend. Some positive experiences are being implemented in Chile, but government priorities are not focused in health promotion. A comprehensive State Policy in health promotion, that includes the public and private sectors related with obesity, is needed to reverse this trend.
