RESUMO
BACKGROUND: Childhood is a basic period for the development of habits and their continuation during the course of life. The objective of this study was to identify food preferences and their variations according to the nutritional status in school-age children living in Mexico City. METHODS: A cross-sectional study was carried out including 1465 school-age children attending eight public elementary schools in Mexico City. Children were asked to complete a questionnaire regarding their preferences to 70 selected different foods. Anthropometric measurements were also carried out. Parents of the children provided sociodemographic information. For each food, the preference was evaluated using a Likert scale. Frequencies were calculated for the total sample and for different nutritional status levels. RESULTS: Median age of children was 9 years old. Forty-eight percent of the children were overweight or obese. The most preferred foods were fruits, pizzas, flavored milk, and French fries. The least preferred foods were vegetables, whole-grain cereals, fish, meat, and panela cheese. Plain water (72%) and sugar-sweetened beverages (71%) had a high level of preference. There was no preference variation according to nutritional status. CONCLUSIONS: Food preference patterns of school-age children are a risk for unhealthy food consumption as well as for the increase in obesity prevalence in this population. Interventions focused on the promotion of a healthy food environment are necessary, aimed at improving food preferences from early childhood.
RESUMO
Abstract Introduction Child obesity is a growing phenomenon and marginalized communities in Mexico City are not exempt from it. The results achieved by frequent preventive and remedial interventions are still unacceptable. Objective To contribute to the understanding of the growing problem of child obesity and overweight through a community health approach capable of transcending the biological perspective in order to improve interventions. Method We observed and interviewed a sample of school children, some overweight, some obese, and some with a normal BMI. All observations and interviews were carried out in the children's daily environment. We also interviewed some of their mothers. Together with our field notes, we analyzed these testimonies to construct the Grounded Theory that is the output of the present study. Results We found the children and their families immersed in a toxic environment that, through several mechanisms, fosters the consumption of high-density foods and discourages physical activity. We also found that the resources and competencies that families could use to fend off this environment are, at present, very limited. Discussion and conclusion We concluded that the energy imbalance in overweight and obese children's bodies corresponds to an abysmal psychosocial imbalance between the forces that foster obesity and the resources of the families affected by it. Any intervention aimed at preventing obesity must take this psychosocial imbalance into account.
Resumen Introducción La obesidad infantil es un fenómeno creciente del cual no quedan exentas las comunidades marginales de la Ciudad de México. Las intervenciones preventivas y remediales son frecuentes, pero sus impactos todavía no son aceptables. Objetivo Contribuir a la comprensión del fenómeno creciente de la obesidad y el sobrepeso infantil con una visión de salud comunitaria, que trascienda la visión biológica del problema y mejore las intervenciones. Método En su entorno escolar y comunitario observamos y entrevistamos a escolares, unos con obesidad o sobrepeso y otros con índice de masa corporal normal. También entrevistamos a las madres de algunos de ellos. Analizamos estos testimonios y nuestras notas de campo para construir la Teoría Fundamentada producto de este estudio. Resultados Encontramos a los niños y sus familias inmersos en un ambiente tóxico que, por múltiples mecanismos, promueve el consumo de alimentos de alta densidad e inhibe la actividad física. Encontramos también que los recursos y habilidades con que las familias podrían resistir a este ambiente son, por lo pronto, muy reducidos. Discusión y conclusión Concluimos que el desbalance energético en el cuerpo de los niños con sobrepeso corresponde a un enorme desbalance psicosocial entre las fuerzas que promueven la obesidad y los recursos de las familias que la sufren. Toda intervención preventiva debe tomar en cuenta este desequilibrio psicosocial.
RESUMO
Introducción: Durante la niñez es fundamental el desarrollo de prácticas saludables que definan buenos hábitos que perdurarán a lo largo de la vida. El objetivo de este estudio fue identificar las preferencias alimentarias y su variación de acuerdo con el estado nutricional de niños escolares en la Ciudad de México. Métodos: Se realizó un estudio transversal que incluyó a 1,456 niños escolares de ocho escuelas públicas en la Ciudad de México. Los niños respondieron un cuestionario autoadministrado sobre sus preferencias de 70 alimentos seleccionados, y se les realizó antropometría; los padres proporcionaron información sociodemográfica de la familia. Se evaluaron las preferencias de cada alimento con escala tipo Likert y se calcularon las frecuencias para el total de niños y por nivel nutricional. Resultados: La mediana de edad de los niños fue de 9 años. El 48.6% tuvo sobrepeso u obesidad. Los alimentos con mayor preferencia fueron frutas, pizzas, leche con sabor y papas a la francesa (fritas). Los alimentos menos preferidos fueron verduras, cereales integrales, pescado, carnes y queso panela. El agua (72%) y las bebidas azucaradas (71%) tuvieron alta preferencia. No se encontraron variaciones en las preferencias con respecto al estado nutricional. Conclusiones: El patrón de preferencias alimentarias de los niños escolares representa un riesgo para el consumo inadecuado de alimentos y para el aumento en la prevalencia de obesidad en esta población. Se requiere de intervenciones oportunas para promover un entorno alimentario saludable y que las preferencias nutricionales sean adecuadas desde edades tempranas.
