Table 3 Association with tuberculosis in different patients’ categories according to vitamin D and glycemic status

From: Association between tuberculosis, diabetes and 25 hydroxyvitamin D in Tanzania: a longitudinal case control study

  Association with tuberculosis
  Adjusted OR (95 % CI)a P value
Normal 25 hydroxyvitamin D level and absence of persistent hyperglycemia Ref. Ref.
Low 25 hydroxyvitamin D level and absence of persistent hyperglycemia 0.70 (0.41–1.20) 0.20
Normal 25 hydroxyvitamin D level and persistent hyperglycemia 0.46 (0.15–1.44) 0.18
Low 25 hydroxyvitamin D level and persistent hyperglycemia 4.0 (0.86–18.54) 0.08
  1. Interaction factor between low 25 hydroxyvitamin D and persistent hyperglycemia: adjusted OR (95%CI) 12.42 (1.78–86.60); pinteraction = 0.01
  2. aAdjusted for age, sex, body mass index, socioeconomic status, mean daily sunshine hours during the month of enrolment and HIV status.
  3. Low vitamin D level <75 nmol/l, Persistent hyperglycemia presence of hyperglycemia at enrolment confirmed at follow up (measure of glycemia repeated among patients with tuberculosis only).
  4. Adjusted odds ratios and p values were calculated using multivariate logistic regression
