Hozawa et al1 showed that only a small proportion of American adults aged 45 to 64 years had low cardiovascular risk, defined as optimal or borderline levels of 4 major modifiable cardiovascular risk factors. It is largely unknown whether this unfavorable epidemiological situation extends to developing countries, although there is some belief that the proportion of individuals at low risk could be larger in these countries.
