P01-115 - Gastrointestinal Discomforts and Food and Nutrients Intake of Chinese Urban Elders: A Cross-Sectional Study in Eight Cities of China

Sunday, Jun 10
8:00 AM – 6:00 PM

Objectives: Gastrointestinal (GI) discomforts are common in the elderly population; however, whether such discomforts are associated with food and nutrients intake has not been studied. This study evaluated GI discomforts in Chinese urban elders and explored its association with food and nutrients intake.

Methods: A multistage sampling method was used to recruit participants from 8 cities of China. The Gastrointestinal Symptom Rating Scale (GSRS) was used to identify GI discomforts in 688 elders. Semi-Quantitative Food Frequency Questionnaire (semi-FFQ) was used to investigate the intake frequencies and amount of 14 food groups. Three dietary patterns were derived from principal component analysis with an orthogonal transformation based on the intake frequencies of 14 food groups. One time of 24-hour dietary recall was used to obtain the data on food intake and calculate the energy and nutrients intake based on the Chinese Food Composition Table (second edition) and the nutrient composition table on the food packaging.

Results: Total of 83% of elders in this study experienced at least one GI discomfort in the past six months, where dyspepsia was the most commonly reported(66.7%), followed with reflux(44.8%) and abdominal pain (35.9% ). Female, lower education level, and lower family income were associated a higher GSRS score. Participants who were diagnosed with a GI- related disease had a higher score on constipation, but a lower score on reflux. Chronic diseases were positively associated with certain GI discomforts. Considering the dietary intake, no associations between dietary patterns and GSRS score were found. The elders with a higher GSRS score had significantly lower intake of bean products. The elders whose GSRS scores were ≥21 and 18~20 decreased their bean products intakes by 7.2g/d and 14.3g/d respectively, comparing with whose GSRS score ≤17. There were no differences in calories and nutrients intake among elders with different GSRS scores.

Conclusion: GI discomforts were common in Chinese urban elders and showed gender, education, and economic differences. GI discomforts were associated with choice of food. A comprehensive dietary strategy for Chinese elders with GI discomforts is needed to ensure healthy aging.
