Assessment of nutritional status and bowel habits in osteoporosis: A cross-sectional, multicenter study of Turkish elderly female population

Abstract

Objective: To investigate the differences in nutritional status and bowel habits between osteoporotic and nonosteoporotic elderly females Methods: Design: A multicenter cross-sectional study. Setting: 12 different provinces of Turkey. Subjects: A total of 1224 elderly free-living postmenopausal Caucasian women (age>65). This study was conducted in accordance with the Declaration of Helsinki. Ethical approval was obtained from the University of Usak Human Research Ethics Committee (HREC) approval number HREC/2018/11. The study was conducted in outpatient clinic of 15 different physical medicine and rehabilitation clinics from 12 different provinces. Participants were informed that the study aimed to determine the differences in nutritional status and bowel habits between osteoporotic and nonosteoporotic elderly females. Written informed consent was obtained from all participants. Inclusion criteria: elderly women (>65) who were performed DXA scans (lumbar spine and hip scan) within 1 month, volunteers for the study who had not received previous treatment for osteoporosis. Exclusion criteria: Chronic glucocorticoid use, malignancy, metabolic bone disease, neurogenic bladder, neurogenic bowel, other malnutrition diseases, use of drugs causing malabsorption, use of drugs causing constipation, nonambulatory status renal failure, and rheumatologic disease. Evaluated variables; Nutritional status as determined by the Mini-Nutritional Assessment (MNA). Bowel habits as assessed by gastrointestinal symptom rating scale (GSRS) and Bristol Stool Form Scale (BSFS). Measurements of BMD of the lumbar spine and left hip using DXA. BMD: DXA measurements were evaluated with the criteria of WHO. T-score between -1.0 and -2.5 accepted as osteopenia and -2.5 and below T-scores accepted as osteoporosis. The patients were divided into the nonosteoporotic group (NOP), osteopenic (OPN) and osteoporotic (OPR) groups. Statistical analysis: The SPSS for Windows 12.0 software package was used for the statistical evaluation of the data. All data were analyzed separately for women and men. Descriptive statistics were analyzed and reported as mean (with standard deviation), or as percentiles as appropriate. One-way ANOVA (analysis of variance) for comparing for three groups on each variable.
