[Diabetes mellitus and ischemie heart disease. Comparison by gender].
OBJECTIVE
To test the association between diabetes mellitus and ischaemic heart disease (IHD) in males and females, after adjusting for known confounders and/or modifiers of effect.


METHODS
The study was designed as a case-control and the period of data collection was one year (March/93 until February/94). The association between diabetes mellitus and IHD was evaluated in each one of two groups: one composed by men the other by women, aged 30-69 years living in the city of São Paulo. The respective samples sizes were 547 and 286. Logistic regression was the statistical method used to do the analysis of the data.


RESULTS
There were similar odds ratios in both genders and diabetes was not considered an independent risk factor for IHD. In each one of the groups the variables hypertension, hypercholesterolemia, smoking and familial history were considered independent risk factors to IHD. The interaction between diabetes and exposures levels of other variables was not statistically significant.


CONCLUSIONS
The presence of major risk factors in the models contributed to the disappearance of the association between diabetes mellitus and IHD.
