The importance of socioeconomic factors in symptoms of heartburn.

INTRODUCTION Patients' socioeconomic status is rarely assessed during medical consultations. OBJECTIVE To correlate patients' socioeconomic conditions with symptoms of heartburn. METHODS 1184 patients who answered a questionnaire in three cities on the coast of the State of Sä Paulo, Brazil, were evaluated prospectively. Socioeconomic status was assessed using several criteria: number of bathrooms, consumer goods present at home, health conditions at home, comfort (cars and/or home helps), monthly family income and head of household's educational level. RESULTS 583 patients (49.2%) reported occurrences of heartburn over the 30 days preceding the consultation, with frequencies ranging from five to thirty episodes over this period. Among patients from the city of Guarujá (low socioeconomic condition), 9.7% had never felt heartburn, while 65.7% reported occurrences, reaching statistical significance in relation to patients of medium socioeconomic condition (city of Sä Vicente) (p = 0.012). There was no difference between patients from medium socioeconomic condition and patients from Santos (high socioeconomic condition) (p = 0.997). There was a statistically significant difference in occurrence of heartburn between the patients with high socioeconomic condition and those of low socioeconomic condition (p = 0.002). CONCLUSIONS The least favored socioeconomic status patients, as confirmed according to a variety of socioeconomic factors, presented greater incidence of heartburn than did the most favored social class.
