Diabetes alert for Hongkongers as researchers find alarming sixfold rise in incidence among ‘high-risk’ individuals
- HKU researchers roll out smartphone app that allows users to regularly assess their risk of developing the disease
- Many people with diabetes are asymptomatic and remain undiagnosed until complications arise, medical experts say
Health experts have urged Hongkongers to be vigilant to the threat of diabetes after a study found an alarming sixfold increase over 15 years among those deemed at high risk of developing the condition.
Researchers from the University of Hong Kong medical faculty issued the public health warning on Thursday as they rolled out a smartphone app allowing residents to regularly assess the risks they faced of developing the metabolic disease, which causes high blood sugar.
They hoped to encourage early diagnosis after finding that the incidence rate of diabetes among 488 people identified as high-risk soared to 33.7 per cent in the 20th year of the study, from 5.5 per cent in its fifth year.
Even for the 1,496 people labelled as low-risk, the incidence rate of diabetes rose to 11.6 per cent in the final year of the study from 1.5 per cent at the five-year mark.
“The study showed an alarming trend about diabetes incidence,” said chair professor in medicine Karen Lam Siu-ling, who led the research.
“However, many people with diabetes are asymptomatic and remain undiagnosed until complications have developed. Early diagnosis in high-risk individuals is therefore important.”
The 20-year survey was the first population-based study with a comprehensive assessment for cardiovascular risk factors, including diabetes, among Hong Kong Chinese.
The “Hong Kong Cardiovascular Risk Factor Prevalence Study” commenced in 1995 and involved about 2,000 participants aged between 25 and 74. It tracked risk factors such as age, hypertension and weight, and cardiovascular diseases.
