URQUIZA-RAMIREZ, César I.; FERNANDEZ DE CORDOVA-AGUIRRE, Juan C.; VELASCO-MEDINA, Andrea A.  y  VELAZQUEZ-SAMANO, Guillermo. Prevalence of Vitamin D deficiency and associated factors in Mexican patients with allergic rhinitis and asthma. Rev. med. Hosp. Gen. Méx. [online]. 2020, vol.83, n.3, pp.113-119.  Epub 06-Sep-2021.

The general population has impaired serum Vitamin D (VD) levels. Poor values are associated with allergic diseases.


The objective of the study was to determine the prevalence of VD deficiency and associated factors in patients with allergic rhinitis and asthma.

Material and methods:

This is a descriptive study in children 3-14 years old, with allergic rhinitis and asthma sensitized to aeroallergens identified by skin prick tests. We measured serum 25-hydroxy VD levels and evaluated associated factors.


Sixty-three patients were included, with a mean age of 7.25 years old, 54% were female. Mean weight was 26.7 kg, mean VD levels were 23.66 ng/ml (± 7.28), 22.2% had sufficient levels, 47.6% had insufficient levels, and 30.2% had deficient levels. We found an association with increased risk of VD deficiency in patients ages 12-14 years old (odds ratio [OR] 7.5, confidence interval [CI] 1.306-43.066), the skin type V with (OR 3.444, IC 2.334-5.083), and the lack of consumption of cod liver supplements (OR 1.475, CI 1.237-1.759).


This sample of Mexican patients with allergic rhinitis and asthma showed the high prevalence of both VD deficiency and insufficiency. Consumption of cod liver supplements was a protective factor for deficiency. No association between VD deficiency and severity of allergic rhinitis and asthma was found in this sample of patients in the Mexican General Hospital of Mexico.
