Objective: to explore whether there is an association between the frequency of insulin resistance and the presence and distribution of acanthosis nigricans in obese children. Materials and methods: this is a cross-sectional study in which 42 obese children between 5 and 10 years of age participated. The presence of acanthosis nigricans was characterized (number and distribution of affected areas) as well as other variables, such as age, sex, and Body Mass Index. Four groups were formed, and the frequency of insulin resistance was determined, aiming to explore its association with the other variables. Results: mean participants’ age was 8.6 years, and male subjects accounted for 54.8%. Nearly two-thirds of participants (64.3%) had acanthosis nigricans, and 78% of them had insulin resistance. Associated variables with statistical significance were age (p= 0.009), BMI (p= 0.025), and the ...

Antecedentes: La obesidad infantil se asocia a la resistencia a la insulina, la cual conlleva a un estado de hiperinsulinemia que genera proliferación de receptores dérmicos, manifestándose clínicamente a través de la acantosis nigricans, un conjunto de placas oscuras en zonas de intertrigo. No se encontraron estudios que relacionen la distribución de la acantosis nigricans en niños con la presencia de resistencia a la insulina. Objetivos: Explorar la asociación entre la frecuencia de resistencia a la insulina y la presencia y distribución de acantosis nigricans en niños con obesidad; así como con edad, sexo, índice de masa corporal y grado de obesidad. Materiales y métodos: Estudio transversal con exploración de asociaciones en el que participaron 42 niños con obesidad entre 5 y 10 años, con un poder de 89.58%. Se registró la presencia y distribución de acantosis nigri...
