Vitamin D deficiency among newly diagnosed tuberculosis patients and their household contacts: a comparative cross-sectional study

Table 3 Proportion of vitamin D deficiency levels among TB patients, community controls and household contacts

Category	TB cases n (%)	Community controls n (%)	P* value	Household contacts n (%)	P** value
Vitamin D deficiency	105(83.3)	47(67.1)	0.009	46(80.7)	0.664
Vitamin D insufficiency	15(11.9)	17(24.3)	0.64	7(12.7)	0.84
Severe vitamin D deficiency	67(53.2)	21(30)	0.002	11(19.3)	<0.001
Normal vitamin D level	6(4.8)	6(8.6)	0.28	1(1.7)	00.32

Chi-square test was used to test for differences in proportions. P* P for difference among TB patients and community controls, P** P for difference among TB patients and house hold contacts, VDD Vitamin D deficiency ((25(OH)-vitamin D₃ ≤ 50 nmol/L)), VDI Vitamin D insufficiency ((25(OH)-vitamin D₃ 51–75 nmol/L)), SVD Severe vitamin D deficiency(25(OH)-vitamin D₃ < 25 nmol/L)
