To explore the effects of low birth weight (LBW) on the body weight and cardiovascular function of teenagers, and to provide theoretical basis for early intervention and prevention of fetal-borne diseases.

From 2006 to 2007, 1200 healthy teenagers who aged from 17 to 22 years old were selected randomly from Yancheng Health Vocational & Technical College and Yancheng Advanced Electrical and Technical School. Informed consent was obtained from all participants. The data of the body weight were collected and the incidence rate of low birth weight was analyzed. Among them, 20 teenagers with low birth weight were included into experiment group and other 20 with normal birth weight were randomly selected into control group. The teenagers in both groups were further examined the body height, weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and cardiac ultrasound.

The incidence rate of low body weight was 11.1% (117/1055). There had no significant difference of body weight and body mass index between two groups (P>0.05), and there had significant difference in systolic blood pressure, diastolic blood pressure, and heart rate (P<0.01). There was no statistically significant difference in the cardiac ultrasound examination (P>0.05).

The low birth weight could increase the risk of hypertension, cardiovascular diseases, so the prevention work should be conducted from fetus stages.
