Hypertension is a global health problem, with the prevalence increasing by 30% from 2013 to 2018 in Indonesia. Furthermore, obesity, a major risk factor for hypertension, has also escalated by 50%. Hence, the incidence of Obstructive Sleep Apnoea Syndrome (OSAS), which is strongly associated with hypertension and obesity, is expected to increase. OSAS is part of the complex sleep disorder breathing syndrome, but there is a lack of data regarding its prevalence and association with hypertension.
To investigate the prevalence of OSAS and its association with hypertension in Jatinangor, West Java, Indonesia.
A cross-sectional study was conducted from September to October 2018 of subjects from two villages in Indonesia selected by purposive sampling. Fifteen neighbourhoods were chosen by the cluster random sampling method, with a total of 1,308 respondents included in this study. Inclusion criteria were age > 17 years old and resident in the village for more than one year. OSAS was determined by a 4-variable screening tool questionnaire (4-V) and hypertension was measured by a standardised method (average of three measurements in each session with a one-minute break using a digital device); both measurements were performed by trained health cadres. All results were statistically analysed using chi-square and logistic regression.
Of the total of 1308 respondents included in this study, 33 (2.5%) had OSAS and 299 respondents (22.8%) had hypertension. In the population with OSAS, 18 respondents (54.5%) had hypertension, significantly higher (p<0.001) compared to the non-OSAS group (22%). After adjustment for age, gender, and Body Mass Index (BMI), OSAS was still an independent predictor of hypertension (OR = 4.3, p = 0.000).
The prevalence of OSAS in the Jatinangor district of Indonesia is 2.5% and it is significantly associated with hypertension.
