Niveles séricos de 25 Hidroxivitamina D en mujeres no menopáusicas, menopáusicas y posmenopáusicas 25-hydroxy vitamin D serum levels in nonmenopausal, menopausal and postmenopausal females
Abstract
Objetivo: evaluar los niveles séricos de 25 hidroxivitamina D (25-OH vitamina D) en mujeres no menopáusicas, menopáusicas y posmenopáusicas, y su relación con algunos factores de riesgo. Materiales y métodos: estudio analítico de cohorte transversal, realizado en 113 mujeres elegidas consecutivamente en la consulta externa de una institución de tercer nivel de complejidad. Se conformaron tres grupos: grupo A, premenopáusicas de 20 a 30 años (n=40); grupo B, menopáusicas de 45 a 55 años (n=40); y grupo C, posmenopáusicas >65 años (n=33). Se comparó el nivel de 25-OH vitamina D en suero a través del estudio ELISA, y su relación con factores como tabaquismo, exposición solar y actividad física en los últimos tres meses. Resultados: el 76% de las mujeres tenían niveles bajos de 25-OH vitamina D (Objective: evaluating 25-hydroxy vitamin D (25OH vitamin D) serum levels in non-menopausal, menopausal and postmenopausal in females and their relationship with dome risk factors. Materials and methods: this was an analytical, cross-sectional study of 113 females chosen consecutively when attending external consultation at a third-level hospital. Three groups were formed: group A, pre-menopausal aged 20-30 (n=40); group B, menopausal aged 45-55 (n=40); and group C, postmenopausal aged >65 (n=33) The levels of 25-OH vitamin D were compared in serum by ELISA and the relationship with smoking, exposure to the sun and physical activity during the last three months. Results: 76% of the females had low 25-OH vitamin D (<25 nmol/L) levels; 80% of the females in group A had low levels compared to 77.5% from group B and 69.7% from group C (p=0.57). There were significant differences between the means of group B’s 25-OH vitamin D values compared to those of group A and C. Analysis of risk factors for reducing 25-OH vitamin D serum levels revealed no significant differences. Conclusions: in spite of our geographical location in the tropics, females from age groups evaluated in this study had low 25-OH vitamin D levels.
