November 5, 2020 updated by: Assoc. Prof. Dr. Rosita Jamaluddin, Universiti Putra Malaysia
Effects of Synbiotics on Functional Constipation and Other Contributing Factors Among Constipated Individuals in Serdang, Selangor, Malaysia
Prevalence of functional constipation (FC) was first determined with 15.2% reported.
Next, a 16-week randomised, double-blind, placebo-controlled study conducted to assess the improvement in functional constipation among the respective individuals by using synbiotic supplement.
Throughout the intervention, it was reported that significant improvements for defecation frequency, Bristol Stool Form (BSF) scale, and Patients Assessment of Constipation Symptoms (PAC-SYM) scores were reported within synbiotic group (p < 0.001).
However, no significant different was reported when compared both groups as placebo group was found to have significant within-group difference too.
Placebo effect was suspected in this study.

Detailed Description
Digestive system disease is the top ten principal causes of morbidity and mortality among Malaysians whereby functional constipation (FC) is the commonest functional gastrointestinal disorders (FGIDs) reported.
Although numerous treatments are available, but over-the-counter drugs which have low product safety and possible toxicity were always given as the treatment option.
Synbiotic have been well-studied to improve digestive health includes constipation.
Thus, the objectives of this study were to determine the prevalence of FC and to evaluate the effects of synbiotic supplement on improving FC symptoms and contributing factors among constipated individuals in Serdang, Selangor.
This study comprised of two parts which were screening and intervention part.
The prevalence of functional constipation was relatively high in the study community.
Synbiotic supplement was effective in the improvement of functional constipation symptoms, quality of life, and psychological factors.
However, the positive improvement in placebo group indicated the existence of placebo effects which led to the improvement in quality of life and changes in psychological factors.
Therefore, the current findings are useful information for future intervention in improving functional constipation symptoms.

Active Comparator: Synbiotic
The product contained three clinically studied active ingredients namely inulin-oligofructose (prebiotic; derived from chicory root), at least 6 billion (B) colony forming unit (CFU) of Lactobacillus plantarum LP01 (probiotic) and 4 B CFU of Bifidobacterium lactis BB12 (probiotic) per sachet.

Placebo Comparator: Placebo
Placebo contains only maltodextrin without any active ingredients, equally same in physical form, freeze-dried white powder with characteristic odor and water soluble as the synbiotic supplement.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Defecation frequency
Time Frame: 16 weeks
|
Defecation frequency was measured through participants' self reported defecation frequency in a week.
|
16 weeks
|
Stool types - Bristol Stool Form (BSF) Scale
Time Frame: 16 weeks
|
BSF scale was used to characterise human stools to seven classifications using seven pictorial presentation of stool types.Type 1 stool shows the very slow transit time with longest time spent in the colon whereas Type 7 indicates the least time spent in the colon and has fast bowel transit time.
Meanwhile, Type 4 is the most ideal stool type optimal colonic transit time.

Constipation symptoms - Patients Assessment of Constipation Symptoms (PAC-SYM)
Time Frame: 16 weeks
|
PAC-SYM consists of a total of 12 questions includes abdominal symptoms, rectal symptoms, and stool symptoms.
It comprised with a 5-point Likert scale ranging from 0 (Absent) to 4 (Very severe).
The values of subscales and total scores for PAC-SYM were then computed as average item response within the scales and for the global score.
Lower score obtained indicates less symptom severity.

Quality of life - Patients Assessment of Constipation Quality of Life (PAC-QOL)
Time Frame: 16 weeks
|
Quality of life was measured using Patients Assessment of Constipation Quality of Life (PAC-QOL).
PAC-QOL consists of a total of 28 questions which was grouped into four domains include physical discomfort, psychological discomfort, worries and concerns, and satisfaction.
It comprised with a 5-point Likert scale ranging from 0 (Not at all/None of the time) to 4 (Extremel/All of the time).The values of subscales and total scores for PAC-QOL scores were then computed as average item response within the scales and for the global score.
Lower score point indicates a better quality of life of the respective participant.

Psychological factor - Depression, Anxiety, and Stress scale (DASS)
Time Frame: 16 weeks
|
Psychological factor was measured using Depression, Anxiety, and Stress scale (DASS).
DASS was used to self-report the severity of depression, anxiety and stress level.
The questionnaire based on 4-point Likert scale, ranging from 0 (Did not apply to me at all) to 3 (Applied to me very much, or most of the time).
