Abstract
Non-communicable diseases (NCD) are defined by The World Health Organization (WHO) as chronic conditions, usually of long duration, and caused by a combination of genetic, physiological, environmental, and behavioural factors. Literature review lays the foundation, as support for a new insight, to summarise and synthesise the arguments and ideas of others and provide a solid background for a research paper’s investigation. It illuminates how knowledge has evolved within the field, highlighting what has already been done, what is generally accepted, what is emerging and what is the current state of thinking on the topic. There were several group differences among those who ‘had been ever diagnosed’ with pre-diabetes/diabetes versus those who had not, by age, employment status, health status, nutrition knowledge, blood pressure/ hypertension diagnosis, and diabetes-related health behaviours.
