The Interaction Between Night Shift Frequency And Age On Hypertension Prevalence Among Female Nurses

Objective:This study aimed to investigate female nurses’ of night shift freque ncy and blood pressure status work in medical institutions at all levels i n Hebei province,and analyze the interaction between age and the freq uency of night shift on the hypertension prevalence.In that way we can provide scientific evidence for arranging the frequency of night shift a nd minimizing the the risk of hypertension in nurses of different age gr oups.Methods:This study used a census questionnaire which was conducted in 512 medical institutions in 11 cities of Hebei Province from November 2016 to July 2018.Binary Logistic regression analysis(stepwise)was done by SPSS Version 26.0(SPSS inc.,IBM).The youngest age group with out night shift was used as reference group.Odds ratio(OR)was calcula ted by different combination of interaction items.Interaction coefficients(r elative excess risk of interaction(RERI),attributable proportion of intera ction(API)and the synergy index(SI)was calculated by Excel table des igned by Andersson to analyze the interaction between age and frequenc y of night shift in hypertension prevalence.Results:Binary Logistic regression results showed that compared with the 18-25 years old ones without night shift,there existed an additive interac tion between the age of 36-45 and more than 5 to 10 night shifts or m ore than 10 night shifts per month on hypertension prevalence.RERI,A PI,SI and their 95% confidence intervals(CI)were 0.631(0.309～0.954),0.216(0.109～0.323),1.488(1.158～1.913),1.037(0.061～2.013),0.303(0.089～0.516)and 1.746(1.093～2.788),respectively.There also existed an additi ve interaction between the age of 46-65 and more than 5 to 10 night s hifts per month on hypertension prevalence.RERI,API,SI and their 95% confidence intervals were 1.809(0.880～2.739),0.245(0.148～0.341)an d 1.394(1.199～1.622),respectively.Conclusions:There existed interaction between specific age group and frequency of night shift on the prevalence of hypertension among female nurses.Nursing managers should reasonably arrange the frequency of night shift according to the characteristics of female at different age groups in or der to decrease the risk of hypertension.
