A Study to Evaluate Association of Sleep Quality with Blood Pressure and Obesity

Background: sleep is crucial for health, influencing both wellbeing and bodily functions. Melatonin, a hormone secreted primarily at night, regulates sleep patterns and supports appropriate behavior. Abnormal sleep pattern can potentially affect different body function and lead to disorders such as obesity and hypertension. Research Methodology: descriptive cross-sectional study was conducted at Medical Research Center, Jamshoro, Pakistan, patients were recruited from Medical outpatient Department; of Liaquat University Hospital Hyderabad/ Jamshoro from May to October 2024. A total of 362 patients included were from both genders and of 18 years and above. Data was collected through structures questionnaire including PSQI, measurement of blood pressure and BMI. Data were analyzed through SPSS (Version 25). Spearman correlation, and regression were used for quantitative variables with 95% CI, Chi Square for categorical variables, p>.05 was considered as significant value. Results: the mean age of the participants was 41 years, SD ± 10.654. Out of the 362 participants 60% were females, and 59% had poor sleep quality. urban dwellers were 63%, married 79%, house wives 57%. There was a significant association with sleep quality, mean of PSQI score was 13.05 ± 4.621. A 63% of participants had no formal education, poor Socioeconomical status (77%), and single type family was 51%, 90% nonsmokers, Muslims were 93%, Sindhi 43%. There was non-significant associated with sleep quality was found. Obesity (mean of BMI 25.88±6.077) was significantly associated with sleep quality, β = 0.039, R= 0.025, r (362) = 0.164, p= 0.002. The mean of blood pressure was (SBP; 121.6±25.442 and DBP 76.69±18.272) not significantly associated with sleep quality respectively β= 0.237, R2 = 0.002, r (362) = 0.034, p = 0.524, β=0.257, R2 =0.004, r (362) = 0.068, p= 0.2. Conclusion: findings concluded that there is a strong relationship between sleep quality and obesity. However, it does not directly affect blood pressure. Though obesity has proven impact on development of hypertension. Further large scale studies are required to explore the relationship further.
