Objectives:
to compare the parameters of the activity/rest cycle of early postpartum breastfeeding women under a controlled and uncontrolled long wavelength ray light regimen.
Methods:
quasi-experimental study with breastfeeding women and their babies during postnatal rooming-in, São Paulo, Brazil. Participants were allocated to either an experimental (intervention) or a comparison group. The intervention involved exposure of the woman in a controlled room with artificial long wavelength ray light at night. Each woman’s level of 6-sulfatoxymelatonin at 24 hours and activity/rest times was analyzed.
Results:
the mean activity/rest times of women in the experimental and comparison groups were similar. The mean percentages of total load of 6-sulfatoxymelatonin during the day and night were similar (p=0.09). At 24 hours, the experimental group presented a significantly lower mean percentage of total load compared to the comparison group (p=0.04).
Conclusions:
women who stayed in the room with long-wavelength artificial light showed no difference in activity/rest and 6-sulfatoxymelatonin levels in the early postpartum period.

Objective:
To identify the predominant chronotype in nursing workers who work in surgical clinics of university hospitals and to verify the association with work shift.
Method:
Cross-sectional study, performed in surgical clinics of university hospitals in the Southern region of Brazil. The sample of 270 nursing workers answered questions of socio-occupational characterization, of health and the Morningness-Eveningness Questionnaire of Horne and Östberg. We performed a descriptive and bivariate analysis with the help of the SPSS software and confidence interval of 95%.
Results:
The indifferent chronotype predominated (45.2%). There were significant differences between occupational categories and variables “age” (p<0.001), “use of medication” (p=0.035) and “choice of work shift” (p=0.001). There was an association between the chronotype and the variables “work leave due to illness” (p=0.021), “children” (p=0.025), “use of medication” (p=0.018) and “work shift” (p=0.001).
Conclusion:
The chronotype remained indifferent, and the results confirmed association between chronotype and work shift.
