Introduction and methods

Body mass index (BMI) is a measure of general adiposity, while waist circumference, waist-to-hip ratio, and waist-to-height ratio, are measures of central adiposity that are more strongly related to CV risk [1,2]. There are important gender differences in body fat distribution, but it is not clear how exactly these differences reflect on CV risk.

In this study, the gender-specific relationship between measures of general and central adiposity and the risk of incident MI was evaluated, in women and men without a prior history of CVD, who were included in the UK Biobank.

The UK Biobank is a large prospective, population-based cohort study, designed to identify associations between baseline characteristics and health outcomes in adults aged 40-69 years [3,4]. For the present analysis, participants with a history of CVD at baseline or with a BMI <15 or >60 kg/m2 were excluded, leaving a sample of 479,610 individuals. The study end point was the incidence of fatal or non-fatal myocardial infarction (MI).

Main results

Conclusion

In a large population-based cohort, the waist-to-hip ratio was more strongly associated with the risk of MI compared with BMI, especially in women. These findings suggest that gender differences in quantity and distribution of adipose tissue may have different implications on the risk of MI.
