Changes in Waist Circumference and the Incidence of Acute Myocardial Infarction in Middle-Aged Men and Women
Figure 1
Hazard ratios (HR) and 95% confidence intervals (CI) of myocardial infarction (MI) according to changes in body mass index (BMI).
Abbreviations: BMI, body mass index. HR, hazard ratio. MI, myocardial infarction Lines are the hazard ratios (shaded areas the 95% confidence intervals) derived from Cox proportional hazard models with changes in changes in body mass index included as restricted cubic splines (3 knots). Reference points are the mean of changes in body mass index. Adjusted for: sex, years between examinations, age, chronic diseases, smoking, Mediterranean diet score, energy intake, education, drinking pattern, sports activity, body mass index in 1993–97, waist circumference in 1993–97 and changes in waist circumference.
