“…8,[16][17][18][19] In observational prospective studies, vitamin A deficiency was associated with an increased rate of respiratory infections, 9,20 but not with rate of AOM. 21 In a cross-sectional, follow-up and interventional trial study performed in Thailand in a population with a vitamin A deficiency similar to that of the current study, Bloem et al 10 found a dose-response relationship between respiratory diseases incidence rates in children and mild vitamin A deficiency.…”

Objective: To assess if vitamin A concentration in umbilical cord blood is associated with incidence and severity of respiratory infections in preschool Inuit children from Nunavik (Québec, Canada). Method: The medical charts of 305 children were reviewed from 0 to 5 years of age. The association between vitamin A concentration in umbilical cord plasma and the incidence rates of acute otitis media (AOM), lower respiratory tract infections (LRTIs) and hospitalization rates for LRTIs was evaluated using Poisson regression. Results: Compared to children with vitamin A concentration ≥20 μg/dl, adjusted rate ratios (RR) for children below 20 μg/dl ranged between 1.06-1.62 for AOM, 1.12-1.34 for LRTIs, and 1.09-1.43 for hospitalization for LRTIs. Most RRs were statistically significant for AOM and LRTIs, but not for hospitalization for LRTIs. Conclusion: Neonatal vitamin A deficiency appears to be a significant risk factor for AOM and LRTIs in this population.

“…The other studies about antioxidant vitamins in the both otitis media [30] and tonsillitis [31,32] demonstrated that the mentioned vitamins were decreased. But, Durand et al [33] did not observe any change in the levels of vitamin A in children with otitis media [33].…”

“…In children, in particular, the most common cause of HL is related to middle ear infections. Therefore, studies on the effect of nutrition on middle ear infections have been reported, and these studies suggest that micronutrient status and vitamin deficiency (such as vitamin A or zinc) may cause more frequent inflammation in the middle ear, leading to increased frequency of otitis media, which increases the risk of HL [69,70,71,72,73,74,75,76,77,78,79,80,81,82,83].…”

“…Therefore, many studies concerning middle ear infection related to HL in children have been reported (Table 4). To summarize these studies, deficiencies of single micronutrients and vitamins (such as zinc, vitamin A, iron, and retinol) are associated with mild ear pathologies such as acute or chronic otitis media [69,70,71,72,73,74,75,76]. In addition, multi-micronutrient supplementation studies have reported that the frequency of HL is significantly reduced when these nutrients are supplied sufficiently [77,78,79,80,81,82,83].…”

Association of Nutritional Factors with Hearing Loss

Hearing loss (HL) is a major public health problem. Nutritional factors can affect a variety of diseases, such as HL, in humans. Thus far, several studies have evaluated the association between nutrition and hearing. These studies found that the incidence of HL was increased with the lack of single micro-nutrients such as vitamins A, B, C, D and E, and zinc, magnesium, selenium, iron and iodine. Higher carbohydrate, fat, and cholesterol intake, or lower protein intake, by individuals corresponded to poorer hearing status. However, higher consumption of polyunsaturated fatty acids corresponded to better hearing status of studied subjects. In addition to malnutrition, obesity was reported as a risk factor for HL. In studies of the relationship between middle ear infection and nutrition in children, it was reported that lack of vitamins A, C and E, and zinc and iron, resulted in poorer healing status due to vulnerability to infection. These studies indicate that various nutritional factors can affect hearing. Therefore, considering that multifactorial nutritional causes are responsible, in part, for HL, provision of proper guidelines for maintaining a proper nutritional status is expected to prevent some of the causes and burden of HL.

Childhood vitamin A status and the risk of otitis media

Abstract: In the range of serum vitamin concentrations found in this population, the status of vitamin A and related compounds in children appeared to have no effect on the incidence of otitis media.
