OBJECTIVE: Compare vitamin D levels in opioid dependence and control population and adjust for relevant confounding effects. Nuclear hormone receptors (including the vitamin D receptor) have been shown to be key transducers and regulators of intracellular metabolism and comprise an important site of pathophysiological immune and metabolic dysregulation potentially contributing towards pro-ageing changes observed in opioid-dependent patients (ODPs).
DESIGN: Longitudinal prospective comparing ODPs with general medical controls (GMCs).
SETTING: Primary care.
PARTICIPANTS: Prospective review comparing 1168 ODP (72.5% men) and 415 GMC (51.6% men, p
INTERVENTIONS: Nil. Observational study only.
PRIMARY AND SECONDARY OUTCOMES: Serum vitamin D levels and relevant biochemical parameters.
RESULTS: Vitamin D levels were higher in the ODP (70.35±1.16 and 57.06±1.81 nmol/L, p
CONCLUSION: Vitamin D was higher in ODP in both sexes in bivariate, cross-sectional, case
