S1635 Gender-Related Difference on Demographics and Comorbidities of Gastroparesis

Abstract

Introduction: Gastroparesis is known to be more prevalent in females than males, even though the pathophysiology behind it remains unclear. There is lack of gender specific comparison of gastroparesis in terms of demographics and comorbidities. The aim of the study was to compare the demographics and comorbidities of gastroparesis between female and male patients. Methods: Patients who had completed a gastric emptying study and diagnosed with gastroparesis were identified using a nationwide database, IBM Explorys (1999-2022). The following conditions were excluded: cyclical vomiting syndrome, psychoactive substance abuse, eating disorder, factitious disorder, chemotherapy, malignant tumor of esophagus and stomach, neoplasm of abdomen, gastric or intestinal obstruction, IBD, adhesion of intestine, carcinomatosis, perforation of intestine, Roux-en-Y gastrojejunostomy, and gastrectomy. Patients were subdivided into males and females. Demographic information, clinical symptoms and comorbidities were collected. Chi-square tests were performed to compare categorical data. Odds Ratios with a 95% confidence interval were reported. Results: A total of 17,570 patients were identified with gastroparesis, of which 13,090 (75%) patients were females and 4,390 (25%) patients were males. Females and males demonstrated similar trend in the distribution of ethnicity: most patients were White (76.6 vs 74.0%), followed by African American (13.0 vs 14.4%) and other races respectively (Table). There was a higher percentage of females than males in the younger age group: age 20-29 (F vs M: 5.3 vs 4.3%) and age 30-39 (F vs M: 13.8 vs 11.4%) respectively. Male patients with GP had a higher prevalence of diabetes mellitus (M vs F: 52.8 vs 42.8%) and other comorbidities, such as: hypertension (64.0 vs 54.5%), hyperlipidemia (57.2 vs 50.1%), chronic kidney disease (24.1 vs 15.8 %), coronary artery disease (26.4 vs 16.6 %) and smoking (16.6 vs 13.8%) (All P value < 0.0001) (Figure). Female patients had a higher prevalence of anxiety (F vs M: 41.3 vs 27.1%), depression (45.8 vs 31.7%), autoimmune conditions (13.8 vs 5.0%) and morbid obesity (15.6 vs 11.6%) (All P value < 0.0001). Conclusion: Female and male patients with gastroparesis demonstrate similar ethnic distribution. There is a higher percentage of female patients than males in the younger age group. However, female and male patients demonstrate different comorbidities.Figure 1.: Comparison of Comorbidities Between Female and Male patients with Gastroparesis.
