A high consumption of soft drinks (SDs) has been linked with the development of anthropometric and metabolic alterations. We evaluate the association between SD consumption and some anthropometric and metabolic variables. This study is an observational study, using a sample of 394 university students, of which 158 were men (40.1%) and 238 women (59.9%), between 18 and 30 years. An SD intake questionnaire provided the consumption of different SDs. The participants’ weight, height, and waist and hip circumferences were collected. Metabolic biomarkers were analyzed. The average intake of caloric SDs (CSDs) was 1193.6 ± 1534.8 mL/week and 84.5 ± 115.02 mL/week for non-caloric SDs (NCSDs). Sex differences were found in the amount of SD consumption and these statistical differences were driven by those men subjects with a high total body fat percentage (TBF%). In men, correlations were found between the intake of CSDs and the body mass index, waist and hip circumferences, TBF%, and visceral fat percentage. In woman, a correlation was found with glucose and triglycerides. The prediction model revealed that the intake of CSDs predicts TBF% and low-density lipoprotein only in men. A high amount of CSD consumption in men was associated with a high TBF%, and this may be predictive of future development of metabolic abnormalities.

Introducción: La economía conductual postula dos procesos ganancias y pérdidas, que en este estudio se evalúan con los beneficios y costos de usar condón. Objetivo: Determinar las propiedades psicométricas (validez y consis­tencia interna) de un instrumento para medir las ganancias y pérdidas para usar condón en una muestra de univer­sitarios mexicanos. Método: Se midieron las ganancias y las pérdidas del condón, así como la frecuencia de uso de condón en una muestra de 257 universitarios, con una edad entre 18 y 39 años (M= 22.34; DE= 3.6) de Querétaro, México. Resultados: Un análisis factorial confirmatorio sugiere la estructura de dos factores sobre ganancias y pér­didas del uso del condón en las relaciones sexuales con un ajuste excelente de los datos. Los resultados apoyaron la validez y confiabilidad del instrumento, además de que las ganancias y las pérdidas predicen el 41.7% de la varianza del uso del condón. Conclusiones: Lo encontrado permite discutir la utilidad de la escala para evaluar conductas de riesgo sexual en diferentes contextos incrementando el uso consistente del condón
