RECRUITINGConstipation symptom improvement
The Bristol Stool Form Scale (BSFS) will be used to assess improvements in constipation. The BSFS is a 9-point scale ranging from 1 to 7, where higher scores indicate softer stool consistency, approaching a liquid state. The specific scoring is as follows: 1. Separate hard lumps, like nuts (difficult to pass) 2. Sausage-shaped but lumpy 3. Like a sausage but with cracks on the surface 4. Like a sausage or snake, smooth and soft 5. Soft blobs with clear-cut edges (passed easily) 6. Fluffy pieces with ragged edges, a mushy stool 7. Watery, no solid pieces, entirely liquid Scores of 4, 5, and 6 are generally considered ideal, indicating smooth bowel movements without constipation. Therefore, higher scores (closer to 4-6) represent improved constipation symptoms, while lower scores (1-3) indicate more severe constipation.
Time frame: 3 weeks
Gut microbiota composition and diversity
Evaluating the changes in the composition and diversity of the gut microbiota before and after the intake of probiotic yogurt using high-throughput sequencing technology.
Time frame: 3 weeks
Emotional state changes
Hospital Anxiety and Depression Scale (HADS) The Hospital Anxiety and Depression Scale (HADS) will be used to quantify changes in participants' emotional state during the study period. The HADS consists of two subscales: one for anxiety (HADS-A) and one for depression (HADS-D), each containing 7 items. Scoring Range: Each subscale is scored from 0 to 21. Interpretation: Higher scores indicate greater levels of anxiety or depression.
Time frame: 3 weeks
Emotional state changes
Depression Anxiety Stress Scales (DASS) The Depression Anxiety Stress Scales (DASS) will be used to assess changes in participants' emotional state during the study period. The DASS includes three subscales: Depression (DASS-D), Anxiety (DASS-A), and Stress (DASS-S), each containing 14 items. Scoring Range: Each subscale is scored from 0 to 42. Interpretation: Higher scores indicate greater levels of depression, anxiety, or stress.
