OBJECTIVES: This study aims to determine the effectiveness of chewing a gum on salivation, passing out of flatus, bowel movement and gastric motility among Filipino elderly. METHODS: The study utilized a quasi-experimental design. A non-probability purposive sampling was utilized in subjects (n=20) selection with inclusion criteria being: (a) Filipino elderly aged 60 years old and above (b) able to chew (c) not taking any laxatives (d) willing to participate. Purposive sampling method was used, divided the respondents into: experimental and control group. Experimental group consisted of 10 subjects while control group 10 subjects. Study was conducted consecutively three days. Lunch was served with a 10 minutes post-lunch rest. The experimental group was given three pellets of chewing gum followed by a rest period of ten minutes-time allotted for masseter muscle to relax. Respondent’s physiologic changes such as salivation, passing of flatus and bowel movement were monitored, data documented. Second phase of gum chewing performed and same process followed. RESULTS: Data revealed that outcome of each elderly in relation to the three physiological processes varies. Salivation yielded a p-value of 0.045 (p value <0.05), passage of flatus obtained a p-value of 0.001 (p value <0.05) and bowel movement has p-value of 0.0429 (p value <0.05), which means there is significant difference between the chewing gum and the non-chewing gum in terms of these three variables.  CONCLUSIONS: Chewing a gum is an effective intervention in enhancing gastric motility among elderly.
