Complex and Bidirectional Interplay Between Marital Quality, Catastrophizing, Psychological Dysfunction, and Quality of Life in Married Malay Women With Disorder of Gut-Brain Interactions.

BACKGROUND

Disorders of gut-brain interactions (DGBI) affect more women, and marital quality may have been a factor that explains clinical manifestations of DGBI-however, the mechanism is unclear. This study aimed to elucidate supported relationships between DGBI with marital quality and clinical attributes in married Malay women.

METHODS

This cross-sectional study involved married Malay women with functional dyspepsia (FD), irritable bowel syndrome (IBS), and FD-IBS overlap per Rome IV criteria. Multivariate analysis of variance (MANOVA) and Pearson correlation analysis were performed to determine the association between DGBI, marital quality, and clinical attributes of catastrophizing, psychological dysfunction, and quality of life. Path analysis models were developed, tested, and fitted to elucidate relationships that satisfied significance testing and fit indices (termed supported relationship).

KEY RESULTS

Of 1130 screened participants, 513 were analyzed. The prevalence of FD, IBS, and FD-IBS overlap was 33.9% (n = 174), 29.5% (n = 151), and 36.6% (n = 188), respectively. Of 17 variables in MANOVA, significant differences in variables were observed for FD vs. FD-IBS overlap (10), IBS versus FD (10), and IBS versus FD-IBS overlap (5). Pearson correlation matrices found significant correlations for 15 of 17 variables. After testing and fitting, the third path model (Model 3) was deemed the final model. Model 3 suggested that relationships between DGBI and marital and clinical attributes were complex and bidirectional. The number of supported relationships were 50, 43, and 39 for FD-IBS overlap, FD, and IBS, respectively.

CONCLUSIONS AND INFERENCES

Relationships between DGBI, marital quality, and clinical attributes among married Malay women are complex and bidirectional.
