Association of sleep time and quality with index in patients with chronic non-communicable diseases

Introduction: With the changes in lifestyle and demands of modern society, the reduction of sleep duration and quality has become common, parallel to the increase in the prevalence of obesity and chronic noncommunicable diseases. Objective: To describe sleep duration and quality and relate them to body mass index, waist circumference and body fat percentage in patients with chronic noncommunicable diseases. Materials and methods: This was a cross-sectional study with patients assisted at a Nutrition outpatient clinic. Sleep duration and quality were assessed using a questionnaire. The variables age, sex, height, body mass index and waist circumference were obtained from the service's standard anamnesis. Weight and fat mass were obtained by bioelectrical impedance. The association between self -reported sleep duration and quality with body mass index, waist circumference and fat mass were tested. A significance level of 5% was considered statistically significant. Results: Sixty-nine patients were evaluated, mostly female (66.7%) and adults (58%). Mean sleep duration was 6.81 hours. The majority (34.8%) of the patients reported always having a good quality of sleep, with this percentage being higher among men than among women (p=0.0077). There was no association between sleep duration or quality and anthropometric variables. Conclusion: Despite the low mean duration of sleep of the participants, there was no association between self -reported duration and quality of sleep with the anthropometric variables evaluated.
