Probiotic awareness was moderate (65%) and use was reported by 54.5% of Saudi residents, with positive perceptions but barriers including limited knowledge (56.2%) and high cost, and usage significantly associated with age, education, marital status, and monthly income.
Key Findings
Results
Probiotic awareness among Saudi participants was moderate, with yogurt being the most recognized probiotic source.
Mean awareness score was 5.2 out of 8 (65%)
Yogurt was identified as a probiotic source by 95% of participants
The study included 286 participants aged 18 years and older, recruited from July to October 2024
The majority of participants were female (79%) and over 30 years old (54.9%)
Results
Participants generally held positive perceptions of probiotics, though barriers to use were reported.
Mean perception score was 3.74 ± 0.60 on a Likert-type scale
Limited knowledge was reported as a barrier by 56.2% of participants
High cost was also identified as a barrier, with a mean score of 3.28 ± 1.09
Barriers also included limited advertising
Results
Probiotic use was reported by over half of respondents, with a strong preference for natural sources.
54.5% of respondents reported using probiotics
71.2% of users preferred natural probiotic sources over supplements
The structured questionnaire used was titled 'Public Knowledge and Perception of Probiotics'
Results
Probiotic usage was significantly associated with several demographic factors.
Age was significantly associated with probiotic use (χ² = 15.251, P < 0.001)
Education level was significantly associated with probiotic use (χ² = 18.787, P < 0.001)
Marital status was significantly associated with probiotic use (χ² = 9.825, P = 0.002)
Monthly income was significantly associated with probiotic use (χ² = 8.548, P = 0.014)
Methods
The study was designed with a required sample size of 269 participants based on a type I error rate of 5% and 80% power, with 286 individuals ultimately enrolled.
Type I error rate (α) = 0.05 and power = 80% were used to calculate the required sample size of 269
286 individuals participated, exceeding the required sample size
The study used a cross-sectional design with a structured questionnaire
Data were analyzed using IBM SPSS version 27
Conclusions
The authors recommended enhanced public health education, improved affordability, and greater healthcare professional involvement to promote probiotic use in Saudi Arabia.
Knowledge gaps, affordability, and limited advertising were identified as persistent challenges
Recommendations included promoting probiotic education through schools and community programs
Supportive health policies to improve affordability were suggested
Greater involvement of healthcare professionals in providing probiotic-related guidance was encouraged
