Role of sleep duration and quality with central obesity in Indians

ABSTRACT

Background: With increasing evidence of association between metabolic diseases with sleep disorders, we tried to look for association between the sleep and various anthropometric parameters of obesity. Objectives: The objectives of this study were to correlate quality and duration of sleep with various grades of obesity. Materials and Methods: About 88 diabesity subjects were included in the study after fulfilling the inclusion and exclusion criterion. There various anthropometric data were collected and sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI) questionnaire. Descriptive and inferential statistical method was done using SPSS 18.0 for data analysis. Pearson correlation, Chi-square, and Fisher’s exact tests were used. Results: The mean PSQI total value for men was 4.45 ± 3.45, and for female, it was 5.85 ± 3.78. The mean PSQI value of rural population was 4.35 ± 3.23 and that of urban population 5.05 ± 3.71. There was increase in the sleep score as grades of obesity increased, but this increase was statistically insignificant (P = 0.265). Pearson correlation coefficient was obtained for anthropometric values and PSQI total. The correlation coefficient r value for was 0.135 for age, 0.080 for waist circumference, 0.081 for hip, −0.039 for waist-hip ratio, and 0.067 for body mass index. Conclusion: The study results showed no correlation between sleep quality as assessed by PSQI and various anthropometric parameters.
