Abstract: Modern people stay up until one or two o'clock in the morning is the norm, making a nighttime snack became a necessity after a long work day. However, evidence for relationship between nighttime snack and human health conditions remained unclear. In this paper, we analyzed the frequency nighttime snacking associated with obesity, hyperlipidemia and hyperglycemia using Chinese teacher cohort. Chinese teacher study contains 22,176 general adults population operated on in 2015. The information of nighttime snacking frequency was acquired by questionnaire. Overweight and obesity outcome were assessed by BMI, and hypertension, hyperlipidemia and hyperglycemia were self-reported. Associations between nighttime snacking consumption and outcomes were performed with multivariable regression and further stratification analyses. We found a significant association (OR 2.11, 95% CI 1.24, 3.62; P for trend < 0.001) between most frequent nighttime snacking and hyperglycemia. And a remarkable association was observed between most frequent consumption of nighttime snack and obesity (OR 3.10, 95% CI 1.63, 5.89; P for trend < 0.001). The present results provide epidemiological evidence that consumption of nighttime snack were associated with obesity and hyperglycemia in Chinese adult teachers. However, the underlying mechanisms still need further investigation.
