Responders addressed questionnaires about lifetime history of iron deficiency > 3 months, diagnosed and treated by a physician, and a history > 3 months of listed pain conditions, anxiety and depression. The emphasis was on life history, not current status, of each of these conditions and such questions were the only practical method. Logistic regression, using generalized estimating equation to account for correlations within twin families, was employed to assess relationships between iron deficiency and pain conditions and the psychological conditions.Results: Of the 1519 adult responders, 1326 addressed the criteria for iron deficiency, and the prevalence was 38.7% in females and 2.4% in males. Iron deficiency as statistical predictor was significantly associated with migraine (Odds ratio (OR)=1.70, p=0.001), headache (OR=1.37, p=0.03), recurrent abdominal pain (OR=1.97, p< 0.001), dysmenorrhea (OR=2.18, p< 0.001), anxiety (OR=1.88, p< 0.001) and depression (OR=2.06, p< 0.001). Iron deficiency, anxiety and depression, as statistical predictors, were univariately and multivariately associated with the number of pain conditions (all p< 0.05).Conclusion: A history of iron deficiency in a community sample of adults was associated with most individual, primary, overlapping and multisite pain conditions tested, and multivariately associated with the number of pain conditions, and with anxiety and depression. We hypothesize, consistent with these results, that previous or current iron deficiency, even when treated, influences pain sensitivity and multiplicity directly and through known effects on anxiety and depression.Keywords: iron deficiency, primary pain conditions, overlapping pain conditions, multisite pain conditions, anxiety, depression, twin family survey, association analyses |
