Prevalence and correlates of snoring among adults in Nigeria.
BACKGROUND
Snoring is a common sleep problem with significant public health concerns. Studies have characterized this in most developed countries. Hitherto there have been no published studies on this subject in Nigeria.


OBJECTIVE
To determine the prevalence and correlates of snoring in addition to morbidity in an adult population in Nigeria.


METHODS
A cross - sectional survey of 370 young adult and adult living in Abuja, Nigeria.. Data were collected on socio- demographic characteristics, sleep pattern as well as occurrence of snoring, apneas and excessive day time sleepiness was determined using Epworth Sleepiness Scale (ESS). Body Mass Index (BMI) and blood pressure were measured.


RESULTS
Of the 370 respondents, 218 (59%) were females. The overall prevalence of snoring was 31.6%; habitual snoring (14%) and moderate snoring (17%). Apnea was reported in about 2% of the respondents while the prevalence of Clinically Suspected Obstructive Sleep Apneas (CSOSA) was 1%, (1.9% in males, 0.5% in females). Snoring was significantly associated with male sex, old age, increased BMI and cigarette consumption . The severity of snoring was also associated with a higher ESS score, day time symptoms and other morbidities.


CONCLUSIONS
Snoring among Nigerians is associated with multiple factors. There is a need for more awareness about this condition in order to control measures of factors associated with snoring.
