Association of 25 Hydroxy Vitamin D Levels with Age in Community Acquired Pneumonia
Background : To determine association of 25
hydroxy vitamin D deficiency with age in patients
with community acquired pneumonia (CAP).
Methods: In this descriptive study 150 diagnosed
patients of community-acquired pneumonia based
on the CURB-65 scoring criteria were enrolled. The
25 hydroxy vitamin D levels were recorded in all
patients. Patients were divided into three groups
according to their age. Effect modifiers like gender
were controlled by stratification. Post stratification
chi square test was applied. A p value of 0.05 was
Results: Mean age of the patients was 40.05 ± 14.33
years (mean ± SD). Out of 150 patients 54.7% (n=82)
were males while the 45.3% (n=68) were females.
The mean level of vitamin D was 18.43 ± 5.005 (mean
± SD) ng/ml. When the cut off value for deficiency
was applied i.e. 20 ng/ml, the 60% (n=90) patients
were found deficient while 40% (n=60) patients had
normal values. The p value was significant only for
the age group to 35 to 50 years. Independent sample t
test showed that the difference is statistically
significant (p=0.003) in age groups between 35 to 50
Conclusions: Lower concentrations of vitamin D
might be associated with CAP particularly in age
group between 35 to 50 years.
