The main modifiable risk factors of the CVD disease are hypertension, hyperglycemia and obesity. This study aims to evaluate the knowledge, awareness and practice on cardiovascular disease risk factors among Gombak community in Kuala Lumpur. Methods: This was a cross-sectional study using self-administered questionnaire and anthropomet- ric measurement among 388 subjects in Gombak District, Kuala Lumpur. Descriptive data analysis and multivariate binary logistic regression were carried to identify demographic and factors associated. Results: The prevalence of the risk factors was high among study subjects, including obesity (24.2%), hypertension (42.3%) and hyperglycemia (26.8%). More than half (64.4%) of the study subjects having at least one of the risk factor. The multivariate binary logistic model factor illustrated that compare to Malays, Chinese were 37% less likely to have obesity (CPR=0.67; 95% Cl: 0.26-1.69). Gombak district community are more likely to have the knowledge on the CVD risk factor but lack of awareness and poor in practicing the prevention action. The Indian ethnic group was less likely to be aware (APR: 0.33, Cl: 0.05-2.31) and others bumiputera ethnic group were less likely to prevent (APR: 0.58, CI: 0.20-1.65) the risk of CVD. The Chinese ethnic less likely to have the knowledge (APR: 0.88, Cl: 0.35-2.22). Conclusion: Gom- bak community was more likely to have the knowledge but less likely to be aware and lack of practice of prevention of the risk factors of CVD.

The overall prevalence of hypercholesterolemia in Malaysia was high (55.4%) Using the Omron blood pressure monitor HEM 7120, compared to awareness rate for hypercholesterolemia blood pressure were measured on the right arm and (39.5%) (11). Moreover, among the Malaysian elderly, supported at the heart level. Hypertension were reflected 79.3% that was given dietary advice, 60.4% of them with the presented average reading of systolic BP >140 were inductively authorized to lose weight and 77.1% mmHg and average diastolic BP > 90mmHg.

The study was conduct using the self-administered Previous study on urban community in Klang, Selangor questionnaire with closed ended questions. The showed the differences in knowledge on diabetes questions were validated, appraised and used in assessing mellitus between different age groups and ethnicity, knowledge, awareness and practice of CVD risk factors thus suggests the structured educational program to (13). The questionnaire consists of four parts, whereby improve the understanding of community on the disease the first part was categorized as the socio-demographic (10). Thus, this study aims to evaluate the knowledge, information, followed by second part of 15 questions awareness and practice on CVD risk factors among on knowledge, third part of 15 questions on awareness Gombak community in Kuala Lumpur. and fourth part of 15 questions on practices on the risk factors of the CVD. MATERIALS AND METHODS Statistical analysis Study design Descriptive statistic was used to analyses the This was a cross-sectional study using self-administered demographic data. One-way ANOVA and Tukey HSD questionnaire. The data were collected from 388 general post-hoc tests were used to determine the significance public residing in the state of Kuala Lumpur, Malaysia. of difference among the demographic groups, such as The study was conducted at the Gombak district, Kuala gender, ethnicity, age group, education level, household Lumpur. The inclusion criteria were male and female > income and occupational. Using the 95% confidence 18 years old and Gombak community who agreed to interval (CI), the overall prevalence of knowledge, participate in the study. This study used standardized awareness and practice were described. Crude and urban population of Malaysia (average of 20 million adjusted prevalence ratio in this study were estimated individuals and equivalent to 72% of the population using the modified Poisson regression. The independent of Malaysia). Centered on the recent national survey, risk factors related to CVD such as gender, age group, we used frequency of the highest CVD risk factors in ethnicity, BMI and highest education were identified Malaysia (hypercholesterolemia) which is 52.9%. Using and controlled for each other using the modified the sample size formula which is [(Z1-α/2)(2p(1-p))]/d2 Poisson regression model. Adjusted prevalence ratio the minimum sample size is equal to 383 (12).
