This study was performed to check the hypothesis that low serum vitamin D and reduced calcium intake may contribute to the comorbidity of psychological symptoms (anxiety and depression) and non-cardiac chest pain (NCCP). The design was a case–control study that involved 40 subjects with NCCP and 40 age and gender-matched healthy controls. Serum vitamin D was assessed using electrochemiluminescence immunoassay; anxiety and depression symptoms were assessed using Hospital Anxiety and Depression Scale, and dietary calcium intake was assessed by self-reporting. Subjects with NCCP had higher anxiety and depression scores and lower vitamin D and dietary calcium intake compared to healthy controls (p < .05). NCCP was associated with anxiety score (odds ratio = 1.40, p < .01). Prevalence of abnormal anxiety score was much higher in subjects with NCCP (47.5%) compared to healthy controls (7.5%). Anxiety score was inversely correlated with vitamin D level and dietary calcium intake (p < .01). Anxiety score was inversely associated with vitamin D level (R2 = .32, p < .05). In conclusion, development of NCCP can be predicted from increased anxiety score which in turn can be predicted from low vitamin D levels. This suggests physicians to consider anxiety and vitamin D deficiency as possible causes for NCCP.
