ABSTRACT: Aims: To determine the prevalence and risk factors of heartburn in Abidjan, a black African city. Patients and Methods: cross-sectional study from June 15 to September 30, 2003. One thousand nine hundred forty (1940) persons from five health zones of the city Abidjan were included after their informed consent. Socio demographic and clinical parameters were collected using a questionnaire in an interview format. Heartburn was defined as a discomfort or burning sensation extending from the sternal manubrium to the base of the neck. Factors related to the complaint were asked such as predisposing factors, habits (tobacco, alcohol and coffee intake) and body mass index. Stepwise multiple logistic regression analyses were used to examine associations between these factors and heartburn. Results: Among 1940 respondents (mean age 28 ± 9 years; sex ratio (M:F) 0.86), heartburn occurred in 433 persons (once a week in 9.2% of case (178 persons)). Five factors were statistically associated with heartburn: male sex (p = 0.025, OR = 0.555 [CI95% 0.331 - 0.930]), heartburn in a family member (p = 0.010, OR = 1.765 [95%CI 1.143 - 2.725]), constipation (p = 0.011, OR = 2.182 [95%CI 11,953,983]), right lateral decubitus (p = 0.001, OR = 6.247 [95%CI 2.079 - 18.775]) and after a meal (p = 0.000, OR = 2.643 [95%CI 1.594 4.383]). Conclusion: Heartburn is common in this black African population. Male sex appears to be less associated. Constipation, right lateral decubitus and after a meal are trigger factors for heartburn. Heartburn in a family member is a risk factor.
