The change in body mass index (BMI) and blood pressure in subjects from the TAMRISK study stratified by whether or not they had hypertension or diabetes by the age of 50
Study group Controls P-value (interaction in change between group and time effects) Difference (95% CI) P-value (t-test)
Change in BMI (kg/m2) 0.04
40 years of age 0.9 (2.3) 0.4 (1.8) 0.43 (0.14;0.72) 0.008
45 years of age 1.8 (2.4) 1.3 (1.8) 0.59 (0.30;0.87) <0.001
50 years of age 2.4 (3.1) 1.7 (2.2) 0.73 (0.36;1.11) <0.001
Change in systolic blood pressure (mmHg) 0.004
40 years of age 2.5 (10.5) 0.6 (8.2) 1.95 (0.54;3.36) 0.007
45 years of age 6.2 (15.5) 2.2 (10.7) 3.99 (1.96;6.03) <0.001
50 years of age 6.2 (20.4) 5.3 (14.1) 0.90 (−1.73;3.53) 0.501
Change in diastolic blood pressure (mmHg) 0.06
40 years of age 2.6 (10.0) 1.4 (7.1) 1.17 (−0.14;2.48) 0.080
45 years of age 4.5 (11.6) 2.4 (7.4) 2.08 (0.58;3.57) 0.007
50 years of age 5.6 (14.0) 5.7 (9.2) −0.16 (−1.95;1.63) 0.859

The change was calculated in relation to baseline (at 35 years of age) during the 15-year follow-up when the periodic health examinations were conducted. Positive values reflect the increase in BMI or blood pressure. Values are means (standard deviations).
