Blood cholesterol	1.57 (1.28 to 1.93), for each 1.0 mmol/l increase	1.67 (1.14 to 2.45), for each 1.0 mmol/l increase

Mean diastolic blood pressure	1.00 (0.99 to 1.01)	NS
§Parental consanguinity v no consanguinity	2.43 (1.46 to 4.04)	3.80 (1.13 to 12.75)
Formal schooling v no school	0.06 (0.02 to 0.17)	0.04 (0.01 to 0.35)
Consume meat	1.50 (0.85 to 2.64)	NS
Monthly income less than v more than Rs 5000	1.81 (1.06 to 3.08)	5.05 (1.71 to 14.96)

Illicit drug use	0.75 (0.26 to 2.16)	NS
Paternal history of CVD v no paternal history of CVD	1.81 (1.06 to 3.08)	4.84 (1.42 to 16.53)

¶Exercise v no exercise	1.75 (1.01 to 3.03)	1.89 (0.52 to 6.85)
Married v unmarried	1.00 (0.51 to 1.96)	NS

*Adjusted odds ratios are based on multivariable model.

†Raised blood glucose defined as fasting blood glucose ⩾6.1 mmol/l (110 mg/dl).

‡NS: these factors were not significantly associated with acute myocardial infarction in the multivariable model and were therefore not included in the final model.

§Parental consanguinity is defined as first cousin marriage between parents of subjects.

¶Exercise was defined as jogging, swimming, bicycling or exercising in the gymnasium most days of the week during the past six months.

CI, confidence interval; CVD, cardiovascular disease.
