an estimated 50% of women experience excessive gestational weight gain (GWG). Maternal body attitudes are associated with GWG, however this relationship is complex and may differ based on pre-pregnancy body mass index (BMI) or gestational age. The aim of this study was to explore the moderating role of maternal pre-pregnancy BMI on the relationship between body attitudes in early-to-mid and late pregnancy and GWG.
DESIGN/PARTICIPANTS: pregnant women less than 18 weeks gestation were recruited for a postal questionnaire study via Australian pregnancy online forums, pregnancy and parenting magazines, and antenatal clinics. In early-mid pregnancy (Time 1; mean (M) = 16.81 weeks gestation, standard deviation (SD) = 1.18), participants reported demographics, pre-pregnancy weight, height, and body attitudes (salience of weight and shape, attractiveness, strength and fitness and feeling fat). In late pregnancy, body attitudes (Time 2; M = 32.65 weeks gestation, SD = 0.91) and weight (Time 3; M = 37.15 weeks gestation, SD = 1.55) were reported. Pre-pregnancy BMI and total GWG were calculated. Moderation analyses were conducted.
in early-mid pregnancy, pre-pregnancy BMI moderated the relationship between feeling fat and GWG. Pre-pregnancy BMI did not moderate the relationship between body attitudes and GWG for salience of weight and shape, attractiveness or strength and fitness in early-mid pregnancy. In late pregnancy, pre-pregnancy BMI moderated the relationship between all four body attitude facets (salience of weight and shape, attractiveness, feeling fat and strength and fitness) and GWG. CONCLUSION/IMPLICATIONS FOR PRACTICE: the relationship between body attitudes and GWG was moderated by pre-pregnancy BMI, particularly in late pregnancy. It is recommended that antenatal health care providers monitor women's body attitudes throughout pregnancy to aid in the management of healthy GWG and promote positive maternal and infant health outcomes. This is particularly important for women entering pregnancy with an underweight/normal weight BMI.
估计有50%的女性孕期体重增加过多（GWG）。孕妇的身体态度与孕期体重增加有关，然而这种关系很复杂，可能因孕前体重指数（BMI）或孕周而异。本研究的目的是探讨孕前BMI对孕早期至中期和晚期身体态度与孕期体重增加之间关系的调节作用。
设计/参与者：通过澳大利亚在线怀孕论坛、怀孕与育儿杂志以及产前诊所，招募妊娠小于18周的孕妇参与一项邮寄问卷调查研究。在孕早期至中期（时间1；平均孕周（M）=16.81周，标准差（SD）=1.18），参与者报告人口统计学信息、孕前体重、身高和身体态度（体重和体型的显著性、吸引力、力量和健康状况以及感觉自己胖）。在孕晚期，报告身体态度（时间2；M = 32.65周，SD = 0.91）和体重（时间3；M = 37.15周，SD = 1.55）。计算孕前BMI和孕期体重总增加量。进行调节分析。
在孕早期至中期，孕前BMI调节了感觉自己胖与孕期体重增加之间的关系。孕前BMI并未调节孕早期至中期体重和体型的显著性、吸引力或力量和健康状况等身体态度与孕期体重增加之间的关系。在孕晚期，孕前BMI调节了所有四个身体态度方面（体重和体型的显著性、吸引力、感觉自己胖以及力量和健康状况）与孕期体重增加之间的关系。
结论/对实践的启示：孕前BMI调节了身体态度与孕期体重增加之间的关系，尤其是在孕晚期。建议产前保健提供者在整个孕期监测女性的身体态度，以帮助管理健康的孕期体重增加，并促进母婴健康的积极结果。这对于孕前BMI偏低/正常的女性尤为重要。
