ABSTRACT
The aims of this cross-sectional study were to examine the developmental characteristics (biological maturation and body size) associated with gross motor coordination problems in 5193 Peruvian children (2787 girls) aged 6-14 years from different geographical locations, and to investigate how the probability that children suffer with gross motor coordination problems varies with physical fitness. Children with gross motor coordination problems were more likely to have lower flexibility and explosive strength levels, having adjusted for age, sex, maturation and study site. Older children were more likely to suffer from gross motor coordination problems, as were those with greater body mass index. However, more mature children were less likely to have gross motor coordination problems, although children who live at sea level or at high altitude were more likely to suffer from gross motor coordination problems than children living in the jungle. Our results provide evidence that children and adolescents with lower physical fitness are more likely to have gross motor coordination difficulties. The identification of youths with gross motor coordination problems and providing them with effective intervention programs is an important priority in order to overcome such developmental problems, and help to improve their general health status.

Objetivos: Documentar la prevalencia de sobrepeso y obesidad en escolares de 6 a 11 años de edad, y determinarla influencia del nivel socioeconómico y de la actividad física sobre ellos. Materiales y métodos: Se evaluaron 4191 niños de siete instituciones educativas de Lima Este. El sobrepeso y la obesidad fueron determinados a través del índice de masa corporal, los niveles de actividad física fueron evaluados a partir del cuestionario de Godin y Shephard y la caracterización del nivel socioeconómico (NSE) fue según la escuela donde cursaban estudios. Resultados: La prevalencia de sobrepeso y obesidad fue de 22 y 7 por ciento respectivamente, 32,9 por ciento de los escolares fueron consideradoscomo poco activos. Los escolares de NSE alto tienen mayor riesgo de presentar sobrepeso (OR: 3,9; IC95 por ciento: 3,1- 4,9) o ser obesos (OR: 11,5; IC95 por ciento: 7,3-18,2)independientemente de la edad, sexo y nivel de actividad física. No se encontróasociación entre los niveles de actividad física y el sobrepeso u obesidad. Conclusiones: La prevalencia de sobrepeso y obesidad que se encontró refuerza la preocupación mundial con la obesidad infantil y sus consecuencias en el futuro. Los factores más influyentes para el sobrepeso y la obesidad fueron el NSE, edad y sexo. La actividad física no presenta ninguna asociación significativa.
Objectives: To document the prevalence of overweight and obesity, as well as to determine the influence of socioeconomicstatus and physical activity levels in body mass index (BMI) of school students aged 6 to 11 years. Material and methods: Be evaluated 4191 children of seven educational institutions of East Lima. Overweight and obesity were assessed by BMI, physical activity levels were evaluated from a questionnaire developed by Godin and Shephard, and for the characterization of socioeconomic status (SES) we used as criteria the school where subjects study. Results: Theprevalence of overweight and obesity was 22 percentage and 7 percentage, respectively, 32,9 percentage of children were considered as little active.The students of higher SES have a great risk of developing overweight (OR: 3,9; 95CI: 3,1- 4,9) or obesity (OR: 11,5;CI95: 7,3-18,2) adjusted to age, sex and physical activity level. No significant association was found between physicalactivity levels and overweight or obesity. Conclusions: The prevalence of overweight and obesity was found reinforce the world concern with infantile obesity and its consequences in the future. The most influential factors of overweight and obesity were SES, age and sex. Physical activity doesnÆt present any significant association.
