Table 3 Crude associations between risk factors for cardiovascular disease and Body Mass Index (BMI) measured in midlife and in early adulthood.

From: The association between BMI and mortality using early adulthood BMI as an instrumental variable for midlife BMI

 

BMI (kg/m2)

Early adulthood (18–20 years)

Midlife (40–50 years)

β (95% CI)

Serum total cholesterol (mmol/L)

0.03 (0.02, 0.03)

0.06 (0.06, 0.07)

Systolic Blood Pressure (mmHg)

0.57 (0.54, 0.60)

1.13 (1.11, 1.15)

Diastolic Blood Pressure (mmHg)

0.39 (0.37, 0.41)

0.72 (0.71, 0.74)

Heart Rate (beats/min)

0.07 (0.04, 0.09)

0.20 (0.19, 0.22)

BMI, early adulthood (kg/m2)

0.38 (0.38, 0.39)

 

Odds Ratio (95% CI)

Smoking, ref: no

1.01 (1.01, 1.02)

0.94 (0.94, 0.94)

Current treatment for hypertension, ref: no

1.16 (1.15, 1.17)

1.19 (1.18, 1.20)

  1. Total cholesterol, systolic and diastolic blood pressure, heart rate, BMI early adulthood: linear regressions. Smoking and current treatment for hypertension: logistic regressions.
