Objective:To analyze the risk factors of pre-pregnancy underweight,overweight or obesity of women of re-productive age in rural areas of Henan province from 2013 to 2018.Methods:A total of 3 686,404 women of reproduc-tive age from the rural areas of Henan province who had participated in the"National free pre-pregnancy health exami-nation project"from 2013 to 2018 were selected as the research objects.Multi-factor logistics regression model was used to analyze the risk factors of the pre-pregnancy underweight,overweight and obesity of the women.Results:The high education level(college/university or above,OR=1.34,95％CI 1.28-1.40),the vegetarian diet(OR=1.06,95％CI 1.01-1.10)and the passive smoking(OR=1.22,95％CI 1.20-1.24)of the women were the risk factors for their pre-pregnancy underweight.The history of pregnancy and birth,the ethnic minorities(OR=1.06,95％CI 1.03-1.10),the vegetarian diet(OR=1.16,95％CI 1.13-1.20),the smoking(OR=1.28,95％CI 1.17-1.41)and the passive smoking(OR=1.04,95％CI 1.03-1.06)of the women were the risk factors for their pre-pregnancy overweight.The history of pregnancy and birth,the vegetarianism(OR=1.15,95％CI 1.09-1.22)and the smoking(OR=1.69,95％CI 1.47-1.93)of the women were the risk factors for their pre-pregnancy obesity.For each additional year of age of the women,the risk of their pre-pregnancy overweight increased by 3％and their risk of pre-pregnancy obesity increased by 2％.According to the geographical location,the western area of Henan province was a risk factors of the pre-pregnancy un-derweight(OR=1.65,95％CI 1.63-1.68)of the women of reproductive age,and the northern area of Henan province was the risk factors of the pre-pregnancy overweight(OR=1.09,95％CI 1.08-1.10)and the pre-pregnancy obesity(OR=1.26,95％CI 1.24-1.28)of the women of reproductive age.Conclusion:The women of reproductive age in Henan province should be paid attention to the problem of their abnormal pre-pregnancy weight,strengthen their weight management,given intervene of their pre-pregnancy weight rationally,and avoid the risk factors that may cause their pre-pregnancy underweight,overweight and obesity,so as to reduce the occurrence of the adverse pregnancy out-comes of the women,and improve the reproductive health of the women of reproductive age.
