About this study

Official title: The Effects of Different Doses of Prune Juice on Bowel Movement Patterns, Constipation Symptoms, and Quality of Life Among Older Adults in Long-Term Care Facilities

This study investigates the effects of different prune juice dosages on bowel movement patterns, constipation symptoms, and quality of life in older adults. Using a factorial experimental design, 90 participants aged 65 to 100 with functional constipation will be randomly assigned to receive 100 mL, 150 mL, or 200 mL of prune juice daily for four weeks. The study aims to determine a safe and effective dosage for constipation management, offering a non-pharmacological approach to improving bowel health in older adults.

Read the detailed description

Constipation is a prevalent issue among older adults, leading to physical discomfort and long-term health complications. Non-pharmacological interventions are essential for effective management. This study aims to compare the effects of different prune juice dosages on bowel movement patterns, constipation symptoms, and quality of life to determine a safe and effective dosage for older adults. A factorial experimental design will be employed, with 90 participants aged 65 to 100 who are conscious, able to express their opinions, and diagnosed with functional constipation. Participants will be randomly assigned to three groups receiving 100 mL, 150 mL, or 200 mL of prune juice daily for four weeks. The outcomes will be assessed at five time points: before the intervention (T0), after one week (T1), after two weeks (T2), after three weeks (T3), and after four weeks (T4).

Being tested
Low-Dose Prune Juice, Medium-Dose Prune Juice, High-Dose Prune Juice

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Stool Consistency Measured by Bristol Stool Form Scale (BSFS)

    Stool consistency will be assessed using the Bristol Stool Form Scale (BSFS), a 7-point scale that classifies stool into 7 types: Type 1 = separate hard lumps Type 7 = entirely liquid Types 3 to 5 are considered normal. The mean change in BSFS score from baseline to Week 4 will be measured. Higher or lower scores reflect changes in stool consistency severity.

    Measured: From study enrollment to the end of the 4-week intervention

  2. Change in Constipation Symptoms Measured by PAC-SYM

    Constipation symptoms will be assessed using the Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire. This instrument includes 12 items across abdominal, stool, and rectal symptom subscales. Each item is rated from 0 (no symptoms) to 4 (very severe). The total score ranges from 0 to 48, with higher scores indicating worse symptoms. The change in total PAC-SYM score from baseline to Week 4 will be evaluated.

    Measured: From study enrollment to the end of the 4-week intervention
