ABSTRACT
AIM: The objective of this study was to evaluate the relationship between FC and physical activity, dietary intake and malnutrition in the elderly. METHOD: A cross-sectional study was conducted on 883 adults aged >65 years from nursing homes and community health centers in Turkey. Constipation status was evaluated according to Rome IV criteria and Bristol Stool Form Scale. Dietary intake was assessed using a food consumption record (24-hour food recall). The dietary energy and nutrients were analyzed using the "Nutrition Information Systems Package Program". The nutritional status of participants was evaluated using the Mini-Nutritional Assessment (MNA) test. The International Physical Activity Questionnaire (IPAQ, short form) was used to assess physical activity status. RESULTS: Among the 883 participants, 29.6% were classified into the FC group (32.2% of females, 25.8% of males). The FC group had significantly lower total energy, fluid, water, protein, carbohydrate, magnesium, zinc, phosphorus, potassium, soluble fiber, insoluble fiber, total fiber, and fiber (g)/1000 kcal intake than the non-FC group (p < 0.05). The multivariate logistic regression analysis showed that total dietary fiber intake was significantly associated with a lower prevalence of FC (OR: 0.98, 95% Cl: 0.96-0.99). According to MNA, participants at risk of malnutrition (OR: 5.21, 95% Cl: 3.09-9.77) and malnourished participants (OR: 3.03, 95% Cl: 1.62-5.68) had a greater likelihood of FC compared with normal participants. Participants in the middle lower quartile of water intake (OR: 0.63, 95% CI: 0.42-0.95) had a decreased likelihood of FC compared with participants in the lowest quartile. CONCLUSION: FC is a common gastrointestinal disorder among the elderly in Turkey. Low dietary fiber intake, low water intake and malnutrition were important risk factors associated with FC in the elderly.
