Objective: To evaluate the sleep duration, the circadian phenotypes, and their association with sociodemographic and clinical variables, lifestyle, and indicators of cardiometabolic risk in adult women. Materials and methods: A cross-sectional study of 108 adult women living in the city of Valencia, Venezuela, who were treated in health campaigns. Sociodemographic and clinical variables, lifestyle, self-reported sleep duration during weekdays and weekends, and weighted sleep duration (short: <7 hours or long: >9 hours) were determined. The circadian phenotype or chronotype were assessed by the reduced Horne & Östberg’s morningness-eveningness questionnaire. Blood pressure, weight, height, waist circumference, and blood biomarkers were measured. Three (3) cardiometabolic status scores were calculated. Hypertension (HTN) and metabolic syndrome (MS) were established. Results: T...

Las adolescentes embarazadas constituyen un grupo de alta vulnerabilidad biológica y social. Objetivo: Evaluar el comportamiento de marcadores plasmáticos del estado redox y perfil lipídico en gestantes adolescentes en el segundo y tercer trimestre de embarazo atendidas en una consulta prenatal pública y compararlo con el que muestran gestantes adultas y mujeres no embarazadas. Material y métodos: Estudio descriptivo transversal, que incluyó 29 gestantes adolescentes (14-20 años), 26 gestantes adultas (20-44 años) y 25 mujeres no embarazadas (17-44 años). Se determinó en suero malondialdehído (MDA), ácido ascórbico (AA), ácido úrico (AU), colesterol total (CT), LDLc, HDLc, triglicéridos (TGL) y se calculó el índice de estrés oxidativo (MDA/AA), relaciones CT/ HDLc, LDLc/HDLc, TGL/HDLc y colesterol NoHDL. Resultados: En ambos trimestres, las gestantes adolescentes mostr...
