Fulltext PDFIndividuals with hypovitaminosis D were studied based their life style as they were of a predominantly an indoor (group 1) or, outdoor style (group 2) or of both (group 3). All were resident of Abu Dhabi (UAE), which is a year -round sunny area. Interestingly, the outcome was not discriminatory as far as the mean values of 25 (OH) D3 and total calcium, and the prevalence of Secondary Hyperparathyroidism (SHPTH) are concerned. They were not different in the 3 groups. The results hence, cast doubts on the impact of the life style on vitamin D inadequacy in this locality and further conclude that merely living in sunny areas does not safeguard against the occurrence of hypovitaminosis D.
Purpose: This report is an attempt to extrapolate more understanding of the relationship between the daily outdoor or indoor life style among patients with hypovitaminosis D (<27 ng /ml) in Abu Dhabi area where the vitamin inadequacy is a very common problem despite the year-round sunny environment.
Methods: Data presented here belong to outpatient adult patients (different socioeconomic classes) in whom the diagnosis of hypovitaminosis D was made based on the assay of 25 OH D3 of <27 ng/ ml. Patients were requested to describe their daily activity as being predominantly indoors ( group 1, G1) or outdoors (group 2, G2)or both (group 3,G3).
Results: After enrolling 150 patients sequentially, the number in G1 outnumbered the other 2 groups individually or collectively (79.5% vs. 8% & 12.5%) respectively, p=0.0001. Interestingly, the mean of 25(OH) D3 and calcium, as well as the prevalence of secondary hyperparathyroidism (SHPT) were not different in the 3 groups. Likewise was the mean age of the patients. No difference was met in the gender data in G1, p=NS, a marginal male predominance in G3, p=0.05 but total absence of female gender in G2, p=0.0001.
Conclusion: Despite the fact that the majority of individuals tends to be indoor either circumstantially or deliberately avoiding excessive heat hence, the contribution of such relation does not seem to have an impact on the hypovitaminosis D status in this area. The outcome was not discriminatory. Studying the skin type scale and other potential lifestyle factors of these individuals may lead to more understanding of this multi-determinant condition.
