Abstract
BackgroundThis study aimed at investigating the CV health and CV disease knowledge in terms of LS7 score among 3 age groups in Hong Kong.MethodsA cross-sectional multicenter observational study was conducted to observe the CV health and disease risk knowledge in Hong Kong. Elderly subjects were recruited from 15 elderly centers, whereas young adults and the middle-aged were recruited from 6 on-campus health check sessions. Subjects’ demographics, lifestyle behavior and risk knowledge were obtained through questionnaire while their body mass index, random capillary blood glucose, blood cholesterol and blood pressure were measured. LS7 score and risk knowledge score was calculated.ResultsThe LS7 of younger adult, middle-aged and elderly were 10.6 ± 1.3, 9.3 ± 1.9 and 9.7 ± 1.7 respectively. Only 0.6% participants have attained ideal CV health and 35.9% have 5 to 7 ideal CV health metrics. Elderly performed worst in risk knowledge with a score of 8.1 ± 3.3 while young adult and middle-aged were similar (9.6 ± 1.8 and 9.7 ± 1.5). 71% of the participants correctly identified ≥9 components. Logistic regression revealed that subjects aged ≤65 years (OR 2.341, 95% CI 1.779 to 3.080) and with tertiary education (OR 2.031, 95% CI 1.527 to 2.701) were more likely to obtain optimum LS7. No association was found between having optimum LS7 and full knowledge.ConclusionOnly few adults in this study population had ideal CV health as defined by AHA. Knowledge has no association but young age and tertiary education has positive association with CV health.
Highlights
This study aimed at investigating the CV health and CV disease knowledge in terms of Life’s Simple 7 (LS7) score among 3 age groups in Hong Kong
Our study revealed that the prevalence of ideal CV health was extremely low among Hong Kong population which is similar to the studies in other countries, with a range of 0.1 to 1.0% [25,26,27,28,29,30]
There was a higher proportion of participants (35.9%) with five or more ideal metrics in Hong Kong than the study conducted by Folsom et al (12.2%), Heart SCORE and HONU Project (21.9%) [26,27,28,29], indicating that the CV health in Hong Kong may be better
Summary
This study aimed at investigating the CV health and CV disease knowledge in terms of LS7 score among 3 age groups in Hong Kong. According to the World Health Organization (WHO) Non-communicable Diseases Country Profiles 2018, CVD were the first leading cause of death globally claiming 17.9 million lives in 2016, which is equivalent to 31% of the total deaths worldwide [1]. The burden of CVD in terms of medical cost is huge in many countries. In the European Union, the overall expenditure on CVD in 2015 was estimated to be €210 billion (HK$2.16 trillion, €1 = HK$10.3), in which only 53% was direct medical cost [2]. The other half came from indirect costs such as productivity loss and informal care, which revealed the profound effect of long-term management of CVD.
