Progresión de talla y peso en niños y niñas entre 6 y 12 años y su diferencia con las tablas de Ramos Galván 40 años después / Height and weight progression patterns in Mexican children aged between 6 and 12 years and differences with Ramos-Galvan growth charts 40 years later

Resumen Introducción: El peso y la talla de niños y adolescentes son un reflejo del estado de salud y desarrollo socioeconómico de la población. Objetivo: Evaluar las progresiones de talla y peso de niños y niñas mexicanos y compararlas con las tablas del doctor Ramos Galván a 40 años de distancia. Método: Encuesta transversal realizada en población del Programa Nacional de Activación Física Ponte al 100, que incluye niños y niñas de seis a 12 años. Resultados: Se evaluaron 43 670 niños y 44 103 niñas, que se estratificaron por sexo y edad. La progresión de talla entre los seis y 12 años fue de 21 cm en hombres y de 22 cm en mujeres; la progresión de peso fue de 9.86 y 10.05 kg, respectivamente para hombres y mujeres. La proporción de niños de seis y 12 años con sobrepeso fue de 11.2 y 9 % y con obesidad, de 14.7 y 15 %. La proporción de niñas de seis y 12 años con sobrepeso fue de 8.2 y 9.1 % y con obesidad, de 21.7 y 13.3 %, respectivamente. Al comparar los valores obtenidos con los de las tablas del doctor Ramos Galván para niños y niñas, el promedio de diferencia fue de 2 cm. Conclusiones: No se documentó un incremento secular de la talla ni del peso en los últimos 40 años.

Abstract Introduction: Children and adolescents weight and height are a reflection of the health status and socioeconomic development of a population. Objective: To evaluate height and weight progression patterns of Mexican children and compare them with Dr. Ramos-Galván growth charts 40 years later. Method: Cross-sectional survey conducted on the population of the National Physical Activation Program Ponte al 100, which includes boys and girls aged 6-12 years. Results: 43,670 boys and 44,103 girls were assessed, stratified by gender and age. The height progression pattern between six and 12 years was 21 cm in males and 22 cm in females, whereas the weight progression pattern was 9.86 and 10.05 kg, respectively, for males and females. The proportion of 6- and 12-year-old boys who were overweight was 11.2 and 9%, while 14.7 and 15% were obese. The proportion of 6- and 12-year-old girls who were overweight was 8.2 and 9.1%, whereas 21.7 and 13.3%, respectively, were obese. When the obtained values were compared with those of Dr. Ramos Galván growth charts for boys and girls, the average difference was 2 cm. Conclusions: No secular height or weight increase within the last 40 years was documented.

The Relationship between Relative BMI Change and Height Growth among Overweight Children / 가정의학회지

BACKGROUND: Many parents of overweight children have believed that their children's weight may be lost with the increase of their height. The purpose of this 2-year prospective study was to examine whether such belief is valid. METHODS: A total of 190 children (113 boys and 77 girls) aged 6-11 years who were overweight (BMI > 85th percentile of age and gender-specific 1999 Korean children standard) from two elementary schools were the subjects. Their height and weight were measured again after 2 years. Children and their parents completed questionnaires on eating habits and physical activity, and their attitude on weight in the beginning of study. Children's weight status was evaluated using relative BMI. RESULTS: Children's baseline relative BMI was 134.9 +/- 13.8%. About 60% of the children reported weight loss attempt and 49% of their parents tried to persuade their child to lose weight. Children's BMI increased by 1.6 +/- 2.1 kg/m2 and their relative BMI decreased by 1.2 +/- 12.1% over 2 years. While children's eating habits and physical activity, and their attitude on the child's weight were not related to the 2-year relative BMI change, the child's age, gender, baseline relative BMI, and the 2-year height change were associated with the 2-year relative BMI change (R2 = 0.15, P < 0.001). The 2-year relative BMI increased with the 2-year height increase after controlling for the three predictors (B = 0.86, SE = 0.28, P = 0.002). CONCLUSION: We found the 2-year height change positively associated with the 2-year relative BMI change among school-aged overweight children. Then, the belief that children's weight status may be improved with the increase of their height should be denied.
