Objective

This study aimed to determine the risk factors of CHD among Malaysian population.

 

Methodology

Using a retrospective observational cohort study design, this study involved 365 adult patients attending medical clinics from public hospitals and health clinics that were selected based on purposive sampling from every region of Malaysia. Sociodemographic characteristics, clinical profile, dietary data, physical activity and stress level were assessed using a structured questionnaire. Multiple logistic regression was used to analyse the associated CHD risk factors.

 

Result & Discussion

In the final model, ten predictors were found to be significantly associated with CHD among this population including age (adjusted OR=1.043, 95% CI=1.009,1.078), smoking status (adjusted OR= 5.089, 95% CI= 2.578,10.045), family history of CHD (adjusted OR= 2.521, 95% CI= 1.385,14.588), marital status (adjusted OR= 0.434, 95% CI= 0.217,0.867), waist circumference (adjusted OR= 1.033, 95% CI= 1.009,1.057), HDL cholesterol (adjusted OR= 0.185, 95% CI= 0.052,0.662), total fat intake (adjusted OR= 1.035, 95% CI= 1.021,1.050) and full cream dairy products intake (adjusted OR= 1.004, 95% CI= 1.001,1.008). Besides, Chinese (adjusted OR= 10.619, 95% CI= 2.255,49.995) and Indian (adjusted OR= 1.975, 95% CI= 0.635,6.146) were more likely to have CHD than Malay and people with income of RM3171-3970 (adjusted OR= 0.198, 95% CI= 0.071,0.553) and RM3971-4850 (adjusted OR= 0.184, 95% CI= 0.063,0.541) were less likely to have CHD than people with income of less than RM2500.

 

Conclusion

Age, race, smoking status, family history, income status, marital status, waist circumference, HDL cholesterol, total fat intake, and full cream dairy products intake were significantly associated with CHD. This finding is particularly important to the primary health care sector to identify at-risk CHD individuals thus appropriate intervention could be provided, although longitudinal prospective studies are required to confirm the association among this population.
