Underweight is an important risk factor for coronary heart disease in the population of Ceningan Island, Bali.

A study on the prevalence of coronary heart disease (CHD) and its risk factors in Ceningan Island was conducted. The prevalence of CHD was 11.5%. Older age (odds ratio, OR, 27.0), underweight (OR, 3.6), systolic hypertension (OR, 4.6), high total cholesterol (OR, 5.9), and high low-density lipoprotein cholesterol (OR, 3.1) were risk factors for a history of myocardial infarction (MI). By logistic regression analysis, only age (B=3.937) and underweight (B=1.275) consistently appeared to be risk factors for MI. The prevalence of CHD in the population was comparatively high.
