AimThe aim of the study was to determine the effects of constipation symptoms and nutritional status on disease-related parameters, such as disease duration, spirometry test and quality of life, of chronic obstructive pulmonary disease (COPD) patients.MethodsThe research was performed with 48 COPD patients attending the centre from January 2019 to August 2019. Assessment of constipation symptoms was done by Constipation Severity Instrument (CSI), whereas for quality of life assessment, St. George's Respiratory Questionnaire (SGRQ) was used. Patient's nutritional status was determined by food frequency questionnaire. Body mass index (BMI) and fat-free mass index (FFMI) of the patients were identified with the bioelectrical impedance analysis (BIA) method. Statistical assessment of data was done with SPSS 22 program.ResultsAccording to the relationship between CSI scores and COPD disease parameters, there was a weak positive correlation between the CSI obstructive defecation subscale and SGRQ activity score and weak positive correlation between CSI colonic inertia subscale and COPD duration from the diagnosis. We found a weak negative correlation between protein intake percentage and SGRQ impact score. As the disease duration increased, the total fat, polyunsaturated fatty acids and vitamin E intake of individuals were determined to reduce.ConclusionAccording to our results, there were some changes in the nutrient intake depending on the duration of COPD, and possible constipation in COPD patients may affect the quality of life.© 2021 John Wiley & Sons Ltd.
