Association of low-carbohydrate diet score with perceived stress score: A cross-sectional study in Iranian nurses

Methods : For the assessment of LCD adherence score, completed three, separate, 24-hour food recall questionnaires. The ten-item PSS questionnaire was also completed. The mean differences in measured parameters between tertiles of LCD adherence score and linear association was checked between LCD score and PSS. Results: Findings showed that higher adherence to LCD score was associated with lower PSS among enrolled nurses ( P = 0.023). In addition, hip circumference was significantly different in tertiles of PSS ( P = 0.01); whilst linear regression showed a significant negative association between LCD adherence score and PSS (β=-0.229; P value = 0.048). Conclusion: The present study suggests that higher LCD adherence score could be associated with lower perceived stress among nurses.
