“…Our findings are consistent with a small sample cross-sectional study conducted in 354 police officers, which concluded that night shift work was associated with decreased kidney function [23]. They also reported that percentage of hours worked on the night shift work was inversely associated with mean levels of eGFR, which was comparable to our results when it comes to the relationship between duration of night shift work, cumulative number of night shifts and eGFR.…”

Background The misalignment between the circadian clock and behavioral cycles has been implicated in pathogenesis of many diseases. However, whether the kidneys are also more prone to disease in the circumstances of chronic circadian rhythms disruption due to night shift work and light at night (LAN) is unclear. The main purpose of this study is to examine the association between rotating night shift work, exposure to light at night, and glomerular filtration rate among steelworkers in north China. Methods A total of 6869 participants, aged 22 to 60 years, were included in this study. Multivariable logistic regression was used to examine the association between night shift work, the brightness of bedroom ambient light at night (LAN), and estimated glomerular filtration rate (eGFR) with adjustment for potential confounders. The relationship between duration of night shift work (continuous), cumulative number of night shifts (continuous), and eGFR were also examined using restricted cubic spline models. Results Long duration of night shift work (≥29 years) had elevated odds of decreased eGFR (OR, 1.39, 95% CI 1.10–1.75) compared with day work after adjustment for potential confounders. Negative associations between duration of night shift work, cumulative number of night shifts, and eGFR (mL/min/1.73 m 2 ) were observed in RCS models. No significant associations were observed among the different brightness of bedroom ambient light levels: middle level (OR, 0.90, 95% CI 0.77–1.05), lightest level (OR, 0.94, 95% CI 0.75–1.17), and decreased eGFR compared with the darkest level. Conclusion The increased duration of night shift work and cumulative number of night shifts among night shift workers, but not the brightness of bedroom ambient LAN, are associated with a slight decline of renal function among steelworkers.

“…Because microalbuminuria is a surrogate marker for assessing glomerular function and represents systemic vascular damage, including damage to vascular endothelial cells, it manifests as dysfunction of endothelial cells [ 26 ]. In a study by Charles et al, shift work was associated with decreased renal function among shift workers compared with day workers [ 27 ]. In addition, an animal study showed that proteinuria was observed in hamsters with SCN removal, suggesting the possibility of direct renal tissue damage.…”

BackgroundShift work disturbs workers’ biological clocks and this condition can cause various health problems including cardiovascular disease. The elevated albuminuria level has been significantly associated with the risk of the cardiovascular disease even within a normal reference range. Therefore, this study aimed to investigate the association between shift work and microalbuminuria.MethodsWorkers aged over 20 years from the fifth and sixth Korea National Health and Nutrition Examination Survey(KNHANES 2012–2014; n = 3000) were included in this analysis. The multiple logistic regression analysis was performed to determine the association between shift work and microalbuminuria stratified by gender.ResultsThe prevalence of microalbuminuria in male subjects was higher among day workers, but the difference was not significant. However, the prevalence of microalbuminuria among females was higher in shift workers with statistical significance. For female, the Odds ratio of microalbuminuria in shift workers was significantly higher with 1.86 (95% CI 1.02–3.39) compared with day workers. After dividing into 5 subgroups of the shift work pattern, the odds ratio of microalbuminuria for fixed night shift was significantly higher at 4.68 (95% CI 1.29–17.00) compared with day workers.ConclusionsThis study showed that shift work was associated with microalbuminuria in female workers. Especially we found out the association between fixed night shift and microalbuminuria in female workers.

“…Briefly, regarding shiftwork (characterized by irregular work hours to provide service throughout a 24 h day), available data suggest that shiftwork, but more so night shiftwork, is a risk factor for negative health outcomes [ 11 , 18 ]. For example, it has been shown that night shift workers tend to have a higher prevalence of overweightness, abdominal obesity [ 20 ], elevated triglycerides, dyslipidemia, impaired glucose tolerance [ 21 , 22 , 23 , 24 , 25 ], and decreased kidney function [ 26 ] compared to day workers. In a study of simulated night shiftwork in normal weight women, reductions in both total daily energy expenditure and the thermic effect of dinner were highlighted as contributing mechanisms for weight gain, obesity and impaired health as a result of shiftwork [ 27 ].…”

Nighttime eating, particularly before bed, has received considerable attention. Limiting and/or avoiding food before nighttime sleep has been proposed as both a weight loss strategy and approach to improve health and body composition. Indeed, negative outcomes have been demonstrated in response to large mixed meals in populations that consume a majority of their daily food intake during the night. However, data is beginning to mount to suggest that negative outcomes may not be consistent when the food choice is small, nutrient-dense, low energy foods and/or single macronutrients rather than large mixed-meals. From this perspective, it appears that a bedtime supply of nutrients can promote positive physiological changes in healthy populations. In addition, when nighttime feeding is combined with exercise training, any adverse effects appear to be eliminated in obese populations. Lastly, in Type I diabetics and those with glycogen storage disease, eating before bed is essential for survival. Nevertheless, nighttime consumption of small (~150 kcals) single nutrients or mixed-meals does not appear to be harmful and may be beneficial for muscle protein synthesis and cardiometabolic health. Future research is warranted to elucidate potential applications of nighttime feeding alone and in combination with exercise in various populations of health and disease.
