AIM
To identify and describe the demographic and social-cognitive factors associated with excessive gestational weight gain using the Weight-Related Behaviours Questionnaire, within an Australian pregnancy cohort.
BACKGROUND
Supporting women to achieve optimal weight gain in pregnancy is complex. Social-cognitive factors are recognised antecedents to, and mediators of, weight related behaviour change. Less is known about their role during pregnancy.
METHODS
159 women enrolled in a pregnancy cohort study completed the Weight-Related Behaviours Questionnaire (WRBQ) at approximately 19 weeks gestation, and total gestational weight gain was later measured at 36 weeks. Summary scores were reported descriptively. Multivariable logistic regression was used to test demographic (maternal age, pre pregnancy body mass index, parity, smoking status, marital status, education) and social-cognitive factors (weight locus of control, self- efficacy, attitudes towards weight gain, body image, feelings about motherhood, career orientation) as predictors of excessive gestational weight gain.
FINDINGS
Maternal age was the sole demographic factor predictive of excessive gestational weight gain. Older participants (34-41 yrs) were less likely to gain excessive weight when compare to younger participants (18-24 yrs): Odds Ratio 0.20, 95% Confidence Interval 0.05, 0.82. Body image (measured as personal satisfaction and perception of own weight) was the sole social-cognitive factor associated with excessive gestational weight gain. For every one unit improvement in body image score, there was a 33% decreased odds of excessive gestational weight gain (OR 0.67, 95% CI 0.53, 0.85).
CONCLUSION
This study suggests that younger maternal age and lower perceived body image are predictive of excessive gestational weight gain.
目的
使用与体重相关行为问卷（Weight-Related Behaviours Questionnaire），在澳大利亚妊娠队列中识别和描述与过度妊娠体重增加相关的人口统计学和社会认知因素。
背景
支持女性在妊娠期间获得最佳体重增加是复杂的。社会认知因素是体重相关行为改变的先行因素和中介因素。关于它们在怀孕期间的作用知之甚少。
方法
159 名参加妊娠队列研究的女性在大约 19 周妊娠时完成了与体重相关行为问卷（WRBQ），并在 36 周时测量了总妊娠体重增加。描述性报告总结得分。多变量逻辑回归用于测试人口统计学因素（母亲年龄、孕前体重指数、产次、吸烟状况、婚姻状况、教育程度）和社会认知因素（体重控制源、自我效能、对体重增加的态度、身体形象、对母亲身份的感觉、职业取向）作为预测过度妊娠体重增加的指标。
发现
母亲年龄是唯一预测过度妊娠体重增加的人口统计学因素。与年轻参与者（18-24 岁）相比，年龄较大的参与者（34-41 岁）不太可能过度增加体重：优势比 0.20，95%置信区间 0.05，0.82。身体形象（衡量为个人满意度和对自己体重的感知）是唯一与过度妊娠体重增加相关的社会认知因素。身体形象评分每提高一个单位，过度妊娠体重增加的几率就会降低 33%（OR 0.67，95%CI 0.53，0.85）。
结论
这项研究表明，较年轻的母亲年龄和较低的身体形象感知与过度妊娠体重增加相关。
