More than half of Hong Kong's adult population has high cholesterol. That figure comes from the government's own data, and it marks one of the sharpest rises in any comparable health indicator the city has recorded in two decades. According to the Department of Health's Population Health Survey 2020–22, hypercholesterolaemia affects 51.9% of adults aged 15 to 84 in Hong Kong. In 2003/04, that number was 8.4%. No rounding error accounts for a gap that wide.
The scale of the shift matters because high LDL cholesterol is one of the most well-established modifiable risk factors for heart disease and stroke. It tends not to cause symptoms, which means many people only find out their levels are elevated through a routine blood test, or after a cardiovascular event. Both outcomes are preventable, and the choices that drive cholesterol upward are, for most people, the same ones that can bring it down.
Understanding why rates have climbed so sharply in Hong Kong, and what actually works to manage them, puts you in a much stronger position, whether you are looking at your first lipid panel result or trying to make sense of a prescription you have already been given.
A six-fold increase in prevalence over roughly two decades is not easily explained by genetics. The more plausible drivers are the structural shifts in how Hong Kong residents eat, move, and age. Diets have shifted toward higher intakes of processed foods, refined carbohydrates, and saturated fat, while physical activity levels across the population have fallen. Urbanisation has extended sedentary working hours. Delivery apps have made calorie-dense food available at every meal.
Ageing adds another layer. The Centre for Health Protection's NCD Watch on cholesterol notes that 42.4% of non-institutionalised adults aged 15 to 84 had total cholesterol at or above 5.2 mmol/L, and 30.0% had elevated LDL concentrations. These figures rise considerably in older age groups. A separate HKUMed and Harvard collaborative study found that 65.6% of people aged 65 to 84 in Hong Kong have high cholesterol, making elevated lipids effectively the norm rather than the exception in that cohort. The fact that Hong Kong has one of the world's oldest populations means the aggregate prevalence figure is being pulled upward simply by demographics.
There is also a detection effect at work. Population-level screening has expanded over the past two decades, and more people are being tested who previously were not. Some of the apparent rise reflects cases that always existed but went uncounted. Even accounting for that, the underlying increase is real and well-documented.
Dietary change is consistently identified as the first line of management for elevated cholesterol, and the Centre for Health Protection describes healthy lifestyle promotion as the best strategy for primary prevention of blood lipid disorders. But "eat healthier" is not a practical instruction. The evidence points to specific dietary patterns rather than single foods.
Saturated fat is the dietary factor with the clearest link to LDL cholesterol. It is found in fatty cuts of meat, full-fat dairy products, coconut oil, palm oil, and many processed snacks and baked goods. Replacing saturated fat with unsaturated fat, particularly from sources like olive oil, nuts, seeds, oily fish, and avocado, is associated with meaningful LDL reductions. This is not about eliminating fat; it is about the composition of the fat you consume.
Soluble fibre is the other significant lever. It works by binding to cholesterol in the digestive tract before it is absorbed into the bloodstream. Oats, barley, legumes, lentils, and many fruits contain meaningful amounts. Increasing fibre intake has a modest but consistent effect that stacks with other dietary changes. For Hong Kong residents eating a traditional Cantonese diet, this often means being more deliberate about including congee with added legumes, steamed tofu dishes, and more vegetable-forward meals alongside, or in place of, dishes heavy in char siu, deep-fried items, or full-fat coconut-based soups.
Dietary cholesterol, found in eggs and shellfish, has a much smaller effect on blood cholesterol than saturated fat does. The older advice to strictly limit egg consumption has been significantly revised in most clinical contexts; the current emphasis is on reducing saturated and trans fats rather than obsessing over dietary cholesterol sources.
Physical activity matters here too. Regular aerobic exercise raises HDL cholesterol, the type that carries LDL away from the arteries. Even moderate activity, spread across the week, produces measurable improvements in the lipid profile. The lifestyle component of cholesterol management is not a warm-up act before medication; for many people it produces substantial results on its own.
For a significant proportion of people, diet and exercise move the numbers but do not bring LDL to a level that adequately reduces cardiovascular risk. This is particularly true for people with familial hypercholesterolaemia, a genetic condition that causes very high LDL from birth regardless of diet, and for those who already have established heart disease or have experienced a cardiovascular event.
Statins are the most commonly prescribed medication for high cholesterol in Hong Kong, and a substantial body of evidence supports their use in people at elevated cardiovascular risk. A landmark study by HKUMed in collaboration with Harvard, published in June 2024, found that continuous statin therapy reduced the relative risk of cardiovascular disease by 21% in adults aged 75 to 84 and by 35% in those aged 85 or above. This was described as a world-first finding, given the previous lack of consensus on statin use in adults over 75. If you are in that age group and have elevated cholesterol, this is a conversation worth having with a doctor.
Despite availability, treatment gaps remain wide. A 2024 paper in the Hong Kong Medical Journal identified persistently low rates of high-intensity statin prescribing, with only 53% of relevant cases receiving it. Roughly 22% of people hospitalised for acute coronary syndrome did not have a lipid profile assessment after discharge. These are not small gaps. They suggest that many people whose cholesterol management has been flagged as a clinical priority are still not receiving the follow-up that evidence supports.
Beyond statins, research published in 2025 in The Lancet Regional Health – Western Pacific analysed nearly 333,000 Chinese individuals with diabetes and chronic kidney disease using Hospital Authority data, and found that despite increasing statin use, significant gaps remain in treatment intensity and LDL target attainment. The study pointed to greater use of combination approaches, including statins alongside ezetimibe or PCSK9 inhibitors, as a path toward closing those gaps. These are specialist-level decisions, but knowing they exist helps you ask more informed questions if your LDL remains stubbornly high despite treatment.
A standard lipid panel measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. It requires a blood draw, usually after fasting for nine to twelve hours, though some clinical settings now use non-fasting panels as a screening tool. Results are returned as a set of numbers that need to be read in context, not as a pass-or-fail score.
What counts as a high-risk LDL depends on your overall cardiovascular risk profile. Someone with no other risk factors has a different target than someone who has already had a heart attack, has diabetes, or has chronic kidney disease. This is why a lipid panel result is a starting point for a clinical conversation rather than a standalone verdict.
The Population Health Survey data and the CHP's published guidance both indicate that large numbers of Hong Kong adults have elevated cholesterol without knowing it. If you have not had a lipid panel in the past few years, particularly if you are over 40 or have a family history of cardiovascular disease, getting one is a straightforward and informative step.
For initial cholesterol testing and basic management, a general practitioner is the appropriate starting point. A GP can order a lipid panel, review your results in the context of your wider health, and either advise on lifestyle changes or initiate medication where that is indicated.
If your cholesterol remains difficult to control, if you have a suspected genetic lipid disorder, or if you have established cardiovascular disease, a referral to a cardiologist or internal medicine specialist with a focus on cardiovascular risk is the usual pathway. Some people with very high or treatment-resistant LDL may be referred to a lipid clinic, where specialist input on combination therapies is available.
Dietitians with experience in cardiometabolic conditions can provide structured support for the dietary side of cholesterol management. Their involvement is particularly useful when lifestyle change is the primary strategy, or when someone wants to make real dietary adjustments alongside medication rather than treating the two as separate tracks.
