Results: The sample had equal gender distribution.Statistically significant relations between older adults' chronic constipation problem and their bowel habits. It shows that the problem is significantly more prevalent among those having no regular bowel habits (p<0.001), hard/loose stools (p<0.001), painful defecation (p<0.001), and it increases with the frequency (p=0.02) and duration of defecation (p<0.001). Conclusion: chronic constipation problem was more prevalent among those having bad teeth, no good sleep, no regular exercise, and non-healthy cooking. Recommendations: Studying factors influencing constipation and modifying their lifestyle using educational interventions by geriatric nurse in various community and healthcare settings.
