Abstract
Effects of sleep disorders on different physiological
functions have been studied in depth. One such association
is that of insomnia and obstructive sleep apnea with
hypertension.
This study intended to evaluate the relationship between
sleep disorders and essential hypertension.
In this institution based case-control study, the study
population was selected by simple random sampling among
all patients attending the outpatient department of Medicine.
Patients with major risk factors for essential hypertension
and other causes of secondary hypertension were excluded.
Patient’s meeting the eligible criteria of blood pressure equal
to or greater than 140/90 (mean of 3 readings) mm of Hg
were included as cases and matched controls were selected
from the rest. The eligible population of 216 people (92
cases, 124 controls) was assessed using the modified
SLEEP-50 questionnaire and evaluated using an original
“Sleep Scale”.
Significant sleep disorder (Sleep Scale score >6), had a
prevalence of 13.89%. The mean sleep scores were
significantly higher (p = 0.0037) in cases than controls.
The association between sleep disorder and essential
hypertension was significant. (Odd’s Ratio=2.270, 95%
Confidence Interval 0.970-5.364, p=0.047).
Sleep disorders are an unconventional risk factor for
essential hypertension. Further studies are needed to validate
the present observations.
