The sample included 181 young children and adolescents between 2 and 18 years of age (88 females, 93 male) from various regions of the city. Relevant data were collected during clinic interviews. Data were analyzed using a chi-square test for nominal data. Interview data were used to compare pre- and post-vitamin D treatment factors.
Results: Psychological manifestations associated with vitamin D deficiency were commonly seen between 6-12 years of age (40.9%), 2-6 years of age (38.1%), and 12-18 years of age (21.0%). Males (51.4%) exhibited higher rate of deficiency when compared to females (48.6%), although this relationship was not statistically significant (pvalue= 0.441).
