認識並管理壞膽固醇水平

Lack of exercise and poor dietary habits are two major causes of high cholesterol. During the pandemic, many people switched to working from home, frequently ordering takeout and reducing physical activity, further increasing the risk of high cholesterol. Research from the Hong Kong College of Cardiology indicates that over 65% of Hong Kong residents are unaware of their ideal LDL cholesterol levels, and even those who are aware fail to take appropriate measures, resulting in an increased risk of high cholesterol and related health problems.cardiovascularThe risk of developing diseases. Furthermore, the survey also found that over 80% of respondents who already had high cholesterol lacked sufficient understanding of related treatments.

This study, commissioned by the Hong Kong College of Cardiology and conducted by the Social Science Research Centre of Hong Kong Baptist University, interviewed 823 Hong Kong residents aged 18 or above from mid-November to early December 2020. The results showed that most respondents understood that lack of exercise (79.31 TP4T), obesity (74.41 TP4T), and trans fat intake (64.51 TP4T) were common causes of high cholesterol, and also knew that high cholesterol could lead to serious complications such as coronary heart disease (79.51 TP4T) and stroke (78.41 TP4T). Furthermore, most people also knew that a low-salt (92.51 TP4T), low-sugar (90.81 TP4T), and low-fat (82.71 TP4T) diet helps maintain health.

However, the survey also found that nearly half of the respondents (47.31 TP4T) were unaware that people with high cholesterol may not have any obvious symptoms, leading many to neglect checkups or medical treatment because they feel perfectly healthy. Furthermore, over 35% of respondents (36.91 TP4T) were unclear that a healthy diet should include high-fiber foods, and only about half (50.21 TP4T) knew they should avoid trans fats, indicating that public awareness of high cholesterol still needs improvement.

Dr. Leung Tat-chi, Honorary Secretary of the Hong Kong College of Cardiology, pointed out that for every 1 mmol/L increase in LDL cholesterol levels, the risk of coronary heart disease increases by 371 Tb/L to 421 Tb/L. Therefore, understanding one's ideal LDL cholesterol level is crucial. The American Heart Association recommends that adults begin having a blood test every 4 to 6 years from age 20 to monitor their cholesterol levels.

The survey found that among respondents aged 18 to 59, nearly one-third (32.51 TP4T) had never had their cholesterol levels checked, and more than 65% (65.71 TP4T) said they didn't know their ideal LDL cholesterol level. In fact, the ideal LDL cholesterol level varies from person to person depending on their individual health condition. For example, for individuals with no history of coronary heart disease and a low cardiovascular risk assessment, it is recommended to keep their LDL cholesterol level below 3.0 mmol/L; while high-risk individuals who have had atherosclerotic cardiovascular diseases, such as angina or myocardial infarction, are considered to be in a very high-risk group and are advised to keep their LDL cholesterol level at 1.4 mmol/L or below, or even reduce it to half or less of its original value.

The survey also revealed that while over 70% of respondents (72.31 TP4T) knew that oral medications could be used to treat high cholesterol, only about 20% (24.11 TP4T) were aware that subcutaneous injections were also an effective treatment option. Even among respondents already diagnosed with high cholesterol, over 80% (83.21 TP4T) were unaware that subcutaneous injections were a treatment option. The Hong Kong College of Cardiology emphasized that drug therapy is...Control high cholesterolIt is an important part of the process, but at the same time, it is recommended that citizens start from their daily lives, improve bad habits, and adopt a "three lows and one high with zero trans fats" diet, namely low oil, low salt, low sugar, high fiber, and zero trans fats, which helps to lower cholesterol levels and maintain cardiovascular health.
