title: [The influence of high birth weight on the blood pressure during childhood - a cohort study].
abstract: OBJECTIVE
  To explore the effects of high birth weight (HBW) on blood pressure (BP) during childhood.
  
  
  METHODS
  A total of 1435 couples with high or normal birth weight were selected from a birth cohort who were born between 1993 and 1995 in Wuxi, China and, followed between 2005 and 2007. A questionnaire survey was conducted, with their height, weight and blood pressure measured.
  
  
  RESULTS
  The medians of systolic blood pressure (SBP) and diastolic BP (DBP) of HBW group were 100 mm Hg (Q(1)-Q(3): 90 - 110 mm Hg), 64 mm Hg (Q(1)-Q(3): 60 - 70 mm Hg) in the high birth weight group, respectively, while they were 100 mm Hg (Q(1)-Q(3): 90 - 108 mm Hg), 62 mm Hg (Q(1)-Q(3): 60 - 70 mm Hg) in the normal weight group. No statistical significant difference was found between the exposed and unexposed groups. The proportion of elevated BP, including pre-hypertension and hypertension, in exposed group was 13.66%, a bit higher than that (11.57%) of the unexposed group (P = 0.055). The relative risk (RR) of HBW on elevated BP was 1.06 (0.92 - 1.21), after adjusted the following parameters as BMI in childhood, sex, age during the follow-up period, age of mother at delivery, gestational age, type of feeding at infancy, dietary habit as well as the frequencies of exercise during childhood.
  
  
  CONCLUSIONS
  No statistically significant correlation was found between high birth weight and blood pressure of children.
