Abdominal Pain of Functional Gastrointestinal Disorders in Dietary Diversity Patterns and Its Determinants among Healthy Adults in Jimma City, Southwest Ethiopia.

Background: Functional Gastrointestinal Disorders (FGIDs) and their risk factors vary from region to region. Therefore, this study aimed to determine the prevalence of abdominal pain of FGIDs in different dietary diversity score (DDS) and its determinant factors among adults in Jimma City, Southwest Ethiopia.

Methods: A community-based cross-sectional study was conducted from July 17 to October 27, 2019. The study included systematically selected healthy adults aged ≥ 18years. Data were collected on gastrointestinal symptoms (Rome III), and DDS (24-dietary recall).

Results: Of 865 healthy adults, the prevalence of abdominal pain symptoms co-occurrence was 168(19.4%), dyspepsia, 152(17.6%) and IBS, 133(15.4). Similarly, the co-occurrence was distributed as 81(9.4%) in middle, 64(7.4%) in high and 23(2.6%) in low DDS groups. Although this distribution was different in the DDS groups, it is not significantly associated. With potential confounders adjusted, the behavioral factors associated with the co-occurrence with an AOR (95% CI) were khat chewing: 7.37 (1.76 - 30.87), drinking alcohol: 3.24 (1.15 - 9.18), sedentary life: 12.28 (3.19 - 48.40) and less physical activity: 4.44 (1.43-13.75). Moreover, elevated TAG: 5.44 (2.78 - 8.10), elevated LDL: 4.26 (1.61-11.29), central obesity: 2.78 (1.08 -7), low HDL 5.89 (2.22-15.60), positive H.pylori stool test: 2.7 (1.86 -7.72), being diabetic: 2.7 (1.79 -7.79) and hypertensive: 2.79 (1.08 - 7.14) were associated with the co-occurrence.

Conclusion: Abdominal pain and FGIDs had significant distribution among adults in Jimma City. Therefore, early screening and managing FGIDs in the community is recommendable.
