Abstract:
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 Nursing Vocational College) in Kunming and Dali in Yunnan Province for a longitudinal study, including baseline survey (T1, November 2021) and three follow up surveys (T2: June 2022, T3: November 2022, T4: June 2023). Sugar sweetened beverages consumption of college students was collected by Semi quantitative Food Frequency Questionnaire and insomnia was assessed by Insomnia Severity Index Scale. Sugarsweetened 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 characteristics, 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 ( χ 2=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 college 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 beverages 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.
