Differences in Serotonin Level and Sleep Quality at The Community Based on Dieting (Vegetarian and Non-Vegetarian)

Abstract

Backgrounds: The food-derived serotonin precursor, Trp, is found in plant proteins that supplement the quantity and quality of night sleep assessed in older adult men and women with difficulty sleeping. Aim: Knowing differences in serum serotonin levels and sleep quality at communities based on diet (vegetarian and non-vegetarian) at Denpasar Bali. Methods: This observational analytic study used a cross-sectional research design with data collection from March 2022. Serotonin D levels were obtained from the subject's blood as much as 3 ml and then checked in the laboratory with serotonin markers. Sleep quality was assessed using the PSQI. Data analysis in this study using independent t-test using SPSS IBM version 23. Results: Mean Serotonin Levels ± SD(ng/dl) in the vegetarian group was 263.74±24.45 while the non-vegetarian group was 202±80. The results of data analysis using an independent t-test showed a mean difference of 73.70 (95% CI 21.56-125.83), p=0.006. Sleep quality with PSQI results in an average± SD of 4.58 ± 2.22 in vegetarians, while in non-vegetarians with PSQI average± SD is 7.13±3.98. The results of the independent t-test analysis showed that the mean difference was 2.55 (95% CI 1.11-3.98), p = 0.001 Conclusion: There are differences in serum serotonin levels and sleep quality in the community based on diet (vegetarian and non-vegetarian), with more high serotonin levels in the vegetarian community and more good sleep quality in the vegetarian community.
