Women who have an overweight or obese pre-pregnancy body mass index (BMI) may be recommended to lose weight before pregnancy, however the association of preconception weight fluctuations and prenatal adherence to nutrition and exercise recommendations with gestational weight gain (GWG) have not been assessed. One hundred women with a pre-pregnancy BMI ≥ 25.0 kg/m² who participated in the Nutrition and Exercise Lifestyle Intervention Program (NELIP) were included and stratified as gained weight excessively (n = 47) or not (n = 53) using the 2009 Institute of Medicine GWG guidelines. Participants completed a Weight Health History Questionnaire providing information about weight loss prior to the index pregnancy. Adherence was scored based on meeting six nutrition and exercise goals for the NELIP (/6). More women who gained excessively reported that they had actively tried to lose weight a year before the current pregnancy (61%) than women who did not gain excessively (39%; p = 0.02). Of the women attempting preconception weight loss, those who gained excessively lost more weight (6.7 ± 10.2 kg) than women who did not (2.1 ± 3.8 kg; p = 0.003). Adherence to the NELIP was lower among women who gained excessively (3.3 ± 0.8; 55%) than those who did not (4.4 ± 0.9;73%; p < 0.001). Program adherence (p < 0.001) was related to excessive GWG.

孕前体重波动以及对产前营养和运动建议的坚持是否与妊娠期体重增加过多有关？

可能建议超重或肥胖的孕前体重指数（BMI）的妇女在怀孕前减肥，但是，孕前体重波动和产前坚持营养和运动建议与孕期体重增加（GWG）的关联尚不明确。评估。一百名孕妇的BMI≥25.0 kg / m ²谁参加了营养和锻炼生活方式干预计划（NELIP）的参与者，并根据2009年医学研究所GWG指南将体重增加了过多（n = 47）或没有（n = 53）。参加者填写了一份“体重健康史调查表”，提供有关指数妊娠前体重减轻的信息。坚持是基于达到NELIP（/ 6）的六个营养和运动目标进行评分的。与那些没有过度增加的女性（39％；p  = 0.02）相比，更多的过度增加的女性表示他们在当前怀孕前一年积极尝试减肥（61％）。在尝试进行孕前减肥的女性中，体重增加过多的女性的体重减轻（6.7±10.2 kg），而没有体重减轻的女性（2.1±3.8 kg; p = 0.003）。过度获得女性（3.3±0.8; 55％）的女性对NELIP的坚持率低于没有获得女性（4.4±0.9; 73％; p  <0.001）的女性。程序的依从性（p  <0.001）与过量的GWG有关。
