Early and current physical activity: relationship with intima-media thickness and metabolic variables in adulthood.
BACKGROUND
It is unclear whether early physical activity has a greater influence on intima-media thickness and metabolic variables than current physical activity.


OBJECTIVE
To analyze the relationship between current and early physical activity, metabolic variables, and intima-media thickness measures in adults.


METHODS
The sample was composed of 55 healthy subjects of both sexes (33 men and 22 women). Total body fat and trunk fat were estimated by dual-energy X-ray absorptiometry. Carotid and femoral intima-media thickness were measured using a Doppler ultrasound device. A 12-hour fasting blood sample collection was taken (fasting glucose and lipid profile). Early physical activity was assessed through face-to-face interview, and the current physical activity was assessed by pedometer (Digi-Walker Yamax, SW200), which was used for a period of seven days.


RESULTS
Current physical activity was negatively related to total cholesterol (rho=-0.31), while early physical activity was negatively related to triglycerides (rho=-0.42), total cholesterol (rho=-0.28), very low density lipoprotein (rho=-0.44), and carotid intima-media thickness (rho=-0.50). In the multivariate model, subjects engaged in sports activities during early life had lower values of very low density lipoprotein (b=-8.74 [b95%CI=-16.1; -1.47]) and carotid intima-media thickness (b=-0.17 [95%CI: -0.28; -0.05]).


CONCLUSIONS
Early 95%CI physical activity has a significant influence on carotid intima-media thickness, regardless of the current physical activity.
