Food frequency questionnaire (FFQ) and demographicvariables were collected for all participants.Results: Meat and dairy consumption was higher among case group (Adjusted OR=5.1, p<0.01, CI=1.08-24.64; Adjusted OR=4.2, p<0.01,CI=1.23-14.29, respectively); while there was a reduction for vegetables intake (Adjusted OR=0.09, p<0.05, CI=0.01-0.876).Conclusion: An increase in meat and dairy consumption and reduction in intake of vegetables seems to be the causes for systemic sclerosis in patients in the area.
