Awareness, consumption patterns, and perceived health risks of non-sugar sweeteners among healthcare students in southern India: A cross-sectional study

Background The widespread use of non-sugar sweeteners (NSS) is a major public health concern, given the potential risks to metabolic and cardiovascular health. This study aims to assess the awareness, perceptions, and consumption patterns of NSS while exploring their potential health effects among healthcare students. Methods This cross-sectional study was conducted among 387 adult health care students. The study tool captured details regarding awareness and perception levels, consumption patterns, side effects and health-seeking behavior toward NSS. The proportions of awareness, perception, consumption patterns and side effects of NSSs were reported with 95% CI. Univariate and multivariable analysis were performed, and the adjusted odds ratio was reported. Results Out of the 387 students, 73.6% (95% CI: 69.1–77.8) were aware of the NSS by name; only 59 [15.2%, 95% CI: 12.1–19.2] knew the FDA’s acceptable daily intake limits and recognised side effects such as abdominal discomfort (61%). Diet sodas (62.8%), health bars/jellies (62.8%), and jams/preserves (41.3%) were the most consumed NSS products. Around 14.5% discussed NSS consumption with consulting physicians. Conclusion This study reveals a significant awareness gap among healthcare students regarding NSS and their long-term health effects, emphasising the need for targeted education on the health risks of NSS consumption within this population.
