Abstract
ObjectiveTo explore effects of the total number of night shifts on BMI of medical workers in recent 5 years.
MethodsThis study was a cross-sectional study. Using the convenient sampling method, data of medical workers in Affiliated Hospital of Jining Medical University were collected from January 2016 to December 2020. The medical examination data of medical workers were obtained from the electronic information system of medical examination center, and the number of night shift and basic information of medical workers are extracted from the human resource management department. The covariates in this study included categorical variables and continuous variables. Categorical variables included gender, job title and job type. Continuous variables included age, working years, systolic blood pressure, diastolic blood pressure, white blood cells, red blood cells, hemoglobin, average hemoglobin volume, platelets, ALT, total bilirubin, total protein, albumin, urea, creatinine, uric acid, triacylglycerol, Total cholesterol, HDL-C, LDL-C and glucose. The relationship between the number of night shift and BMI was processed by generalized addition model and smoothing curve fitting.
ResultsFinally, a total of 908 medical workers were selected for data analysis. The average number of night shifts for 908 medical workers in 5 years was (339.0±30.8) , and the average BMI was (22.88±2.08) kg/m2. After adjusting for confounding factors, the number of night shift showed a non-linear relationship with BMI, and the number of inflection points was 634. On the left of the inflection point, there was no significant relationship between the number of night shifts and BMI (P=0.829) . The relationship between the two on the right side of the inflection point was significant, the effect size and 95% confidence interval were 0.02 and 0.01-0.03, respectively.
ConclusionsBMI value of medical workers increases significantly with the increase of night shift number when the number of night shift is more than 634 in recent 5 years. Hospital managers can calculate and plan the number of night shifts per year to reduce the effect of night shifts on the health of medical workers.
