In Hong Kong, diabetes is an important public health issue. The Population Health Survey 2014/15 of the Department of Health collected data of both diagnosed and undiagnosed cases of diabetes through self-reporting of existing diagnosis and biomedical testing respectively. The survey observed that 3.8% of the persons aged 15 – 84 (4.6% for males; 3.2% for females) self-reported of having doctor-diagnosed diabetes and another 4.5% (6.0% for males; 3.2% for females) were previously undiagnosed but tested to have diabetes during health examination. Combining the self-reported doctor-diagnosed and biochemical testing detected cases, the total prevalence of diabetes among local population aged 15 – 84 was 8.4% (10.5% for males; 6.4% for females), with about half of them being undiagnosed before the survey.
Diabetes is a major cause of death in Hong Kong. In 2021, it claimed 548 registered deaths (provisional figures), and was the tenth leading cause of death in Hong Kong, accounting for 1.1% of all registered deaths.
