Relación entre ingesta dietética de calcio y adiposidad corporal en adolescentes mujeres / Relationship between dietary calcium intake and adiposity in female adolescents

Antecedentes y objetivo: La prevalencia y magnitud de la obesidad en niños y adolescentes se incrementa aceleradamente. Aparte de los factores genéticos y ambientales, se ha identificado recientemente la ingesta de calcio dietético como uno de los factores que se correlaciona inversamente con el índice de masa corporal y con el desarrollo de sobrepeso y obesidad. El objetivo del presente estudio es determinar la correlación entre la ingesta dietética de calcio con el índice de masa corporal y la distribución de la grasa en adolescentes mujeres. Materiales y métodos: Es un estudio de corte transversal en el cual se realizó la evaluación antropométrica (peso, talla, índice de masa corporal, circunferencia de cintura, circunferencia de cadera) en 244 adolescentes mujeres, para establecer la adiposidad corporal total y la distribución de la grasa. Se utilizó el recordatorio de 24 h y un cuestionario de frecuencia de consumo para determinar la ingesta calórica total, ingesta de calcio y consumo de lácteos. Resultados: La ingesta de calcio se correlacionó inversamente con el índice de masa corporal (p < 0,05), circunferencia de cintura (p < 0,05), circunferencia de cadera (p > 0,05) e índice cintura cadera (p < 0,05). Las adolescentes con sobrepeso (8,3%) y obesidad (0,7%) tuvieron una ingesta promedio de calcio inferior al de las adolescentes de peso normal (p = 0,06) Conclusiones: La ingesta dietética de calcio y en menor grado el consumo de productos lácteos se relaciona inversamente con la adiposidad total y abdominal así como con la prevalencia de sobrepeso en las adolescentes estudiadas (AU)

Background and objective: The prevalence and magnitude of obesity in children and adolescents increase rapidly. Besides genetic and environmental factors, calcium intake has recently been identified as a dietary factor that is inversely related with body mass index and development of overweight and obesity. The purpose of this study was to assess the correlation between dietary calcium intake and body mass index and fat distribution in female adolescents. Materials and methods: This was a cross-sectional study where anthropometric variables (weight, height, body mass index, waist and hip circumference) were collected in 244 female adolescents to establish total body adiposity and fat distribution. A 24-hour recall and a food frequency questionnaire were used to assess total calorie, calcium, and dairy products intake. Results: Calcium intake was inversely related to body mass index (P < .05), waist circumference(P < .05), hip circumference (P > .05), and waist to hip ratio (P < .05).Overweight (8.3%) and obese (0.7%) adolescents had a lower mean calcium intake than adolescents of normal weight (P = .06). Conclusions: Dietary calcium intake and, to a lesser extent, consumption of dairy products are inversely related to total and abdominal adiposity, and also to the prevalence of overweight in this group of adolescents (AU)
