Association between perception of sleep quality, body composition and glucose level in Peruvian adults

Abstract

Background: Perception of sleep quality refers to how a person evaluates or rates the quality of his or her sleep. However, there are few studies that explore how it relates to specific aspects of physical health. Therefore, the aim of this study was to investigate the association between the perception of sleep quality, body composition and glucose level in a sample of Peruvian adults. Methods: A cross-sectional study was conducted in 63 participants aged 18 to 63 years who are part of two Adventist entities in the city of Lima, Peru. The data were analyzed using Chi-square and Mann-Whitney U tests, considering a significance level of 5%. Results: Of the total participants who reported perceived suboptimal sleep quality, 48.7% had excess body weight, however, no significant association was observed, p > 0.05. Interestingly, those with optimal sleep perception had a significantly higher body fat percentage (37.5 ± 6.3) relative to those with non-optimal perception (35.3 ± 7.2), p < 0.05. On the other hand, those who reported optimal perception of sleep quality had a higher muscle mass score (23.9 ± 5.5), however, there was no significant association, p > 0.05. Of the 100% of those reporting perceived suboptimal sleep quality, 53.8% were prediabetic, p < 0.05. Conclusion: These findings underscore the importance of implementing education programs aimed at improving sleep quality and decreasing the risk of noncommunicable diseases.
