The first three months of pregnancy are crucial, as poor fetus growth during this time may be associated to cardiovascular issues in the future, reports Science Daily.

Researchers from the Netherlands worked with 1,184 school age children with crown to rump measurements during the first trimester. Upon reaching six years old, data on their cardiovascular health, body mass index, body fat distribution were analyzed. Blood pressure, insulin, and cholesterol levels were also taken into account.

According to the results, those who had the smallest crown to rump measurements during the first trimester were more likely to have higher total fat mass and higher diastolic blood pressure at age six, making them more vulnerable to cardiovascular issues.

Although there are many other factors that can affect the health of school age children, researchers believe that the first trimester is still very important with regard to cardiovascular and metabolic development.

Experts recommend that mothers eat healthy and stay hydrated, especially in their first trimester. A bit of exercise and a lot of rest may also help the body compensate for the new life growing within.
