title: [Influence of low birth weight on the increased risk of post-partum hypertension].
abstract: OBJECTIVE
  To compare the prevalence of hypertension between low birth weight infant (LBWI) women and non-LBWI women.
  
  
  METHODS
  A retrospective cohort study was applied and 3 172 pregnant women giving births during October 1976 to December 2008 in our hospital and underwent physical check-up between 2010 and 2011 at the Kailuan medical group were included and divided into LBWI group and non-LBWI group by the history of LBWI. Prevalence of hypertension was obtained during the follow-up program. Multiple logistic regression analysis was used to assess the relative risk of hypertension.
  
  
  RESULTS
  A total number of 3 172 women, with an average age of 42.3 years old were divided into LBWI group (n = 147) and non-LBWI group (n = 3 025), with the average birth weights of their infants were 2.31 kg and 3.39 kg, respectively. The prevalence of hypertension from the follow-up program was significantly higher in LBWI group than that in the non-LBWI group (23.8% vs. 16.9%, P < 0.05). After adjustment for other traditional risk factors, the risk of hypertension in LBWI group was 1.60 (95%CI:1.02-2.53) folds higher than that in the non-LBWI group.
  
  
  CONCLUSIONS
  Prevalence of hypertension in women with LBWI was higher than that in those women without LBWI. History of LBWI seemed to have had an increased risk to develop hypertension.
