Objective To study the relationship between sugar-sweetened beverages consumption characteristics and insomnia of college students in Yunnan Province,so as to provide evidence for sleep quality improvement of college students.Methods A cluster random sampling method was used to select 2 515 college students from two universities(Kunming University and Dali Nurs-ing Vocational College)in Kunming and Dali in Yunnan Province for a longitudinal study,including baseline survey(T1,Novem-ber 2021)and three follow-up surveys(T2:June 2022,T3:November 2022,T4:June 2023).Sugar-sweetened beverages con-sumption of college students was collected by Semi-quantitative Food Frequency Questionnaire and insomnia was assessed by Insom-nia Severity Index Scale.Sugar-sweetened beverages consumption was analyzed by Kruskal-Wallis test.The Mann-Whiter U test and Kruskal-Wallis test were used to compare the detection rate of insomnia in college students with different population character-istics,and the generalized estimating equations model was established to analyze the association between sugar-sweetened beverages consumption and insomnia.Results The reported rate of insomnia among college students from T1 to T4 was 21.2％,23.6％,30.5％and 36.0％,respectively.The median of sugar-sweetened beverages consumption per week was 5(1,9)bottles per person,and there were significant differences in sugar-sweetened beverages(carbonated beverages,fruit beverages,tea beverages,milk beverages,energy beverages)consumption among college students with different insomnia status(x2=42.91,23.67,29.98,61.70,30.82,P＜0.01).The analysis of the generalized estimating equation model revealed that the consumption of carbonated beverages(β=0.04,95％CI=0.00-0.08)and the consumption of milk beverages among college students(β=0.04,95％CI=0.00-0.09)were correlated with insomnia(P＜0.05).The stratified analysis indicated that consumption of carbonated beverages by female col-lege students was associated with insomnia[β(95％CI)=0.06(0.01-0.11)];consumption of milk beverages among college students from middle-income family was associated with insomnia[β(95％CI)=0.05(0.00-0.10)],and consumption of carbonated bevera-ges and fruit beverages from college students with high household economic status were both associated with insomnia[β(95％CI)=0.35(0.23-0.46),0.12(0.00-0.24)](P＜0.05).Conclusion Sugar-sweetened beverages,especially carbonated beverages,are associated with insomnia among college students in Yunnan Province.
