title: [Evaluation of pre-pregnancy weight and gestational weight gain among urban and rural women from southwestern China].
abstract: OBJECTIVE
  To evaluate the situation of pre-pregnancy weight and gestational weight gain (GWG) of women in the urban and rural areas of southwest of China.
  
  
  METHODS
  Total 3391 women whose infants and young children aged 6 - 24 months were selected from urban and rural areas of Kunming, Guiyang and Chengdu cities by stratified cluster random sampling. Data of pre-pregnancy height and weight, prenatal weight and pregnancy age for subjects was obtained using a questionnaire. Pre-pregnancy BMI and GWG were calculated. According to the BMI standard for adults from WHO and GWG Guidelines from IOM (2009), the status of pre-pregnancy weight and GWG were assessed.
  
  
  RESULTS
  Average BMI of pre-pregnancy for them is (20.3 +/- 2.4). Percentage of normal weight, underweight, and overweight/obesity of pre-pregnancy were 72.7%, 24.1% and 3.2% respectively. The average GWG was (14.9 +/- 6.0) kg, and there was a significant difference between urban and rural group (P < 0.05). Percentage of normal, insufficient and excessive GWG were 35.3%, 31.1% and 33.3% respectively. The rate of excessive GWG in urban group was higher than rural group (P < 0.05), but the rate of insufficient GWG was lower (P < 0.05). The rate of insufficient GWG was higher in women aged below 23 years old (P < 0.05), and the rate of excessive GWG was higher in women aged 24 - 34 years old (P < 0.05).
  
  
  CONCLUSIONS
  It should be pay more attention to improve the underweight of pre-pregnancy and abnormal GWG among women in the southwest of China.
