The National Health Survey was carried out in 2017 in all the governorates of the sultanate. MoH, represented by the Research Centre at the Directorate General of Planning and Studies, carried out the survey.
The survey was carried out in coordination with the competent departments of MoH and the World Health Organization on a sample of 9,045 Omani and non-Omani families spread across the sultanate.
The sample was selected as a multi-stage stratum based on the geographical distribution of the 2010 census. An equal number of households were selected in each governorate. One individual was randomly chosen to participate in the survey.
Non-communicable diseases are long term and generally have a slow onset such as cardiovascular disease (heart attacks and stroke), cancers, chronic respiratory diseases (such as chronic obstructive pulmonary disease and asthma) and diabetes.
The risk factors that cause non-communicable diseases are divided into behavioural – which can be changed, such as tobacco use, physical inactivity, alcohol abuse and unhealthy diet - and biological - such as high blood pressure, obesity, high blood sugar. All these factors increase the risk of death.
