To describe the weight histories of women with extreme or class III obesity (BMI >or= 40 kg/m(2)) in comparison with a sample of women with class I-II obesity (BMI < 40 kg/m(2)) and to provide reliability data for a clinical instrument that assesses weight history.
Female patients (N = 149) with extreme obesity seeking bariatric surgery and 90 class I-II obese women seeking behavioral treatment completed the Weight and Lifestyle Inventory (WALI), a self-report instrument that assesses age of onset of obesity, maximum weight at different ages, family weight history, and weight changes related to pregnancy. Test-retest reliability data were obtained by administering the WALI to a subsample (n = 58) of class I-II obese participants at their initial visit and at another pretreatment visit 1 to 2 weeks later.
Patients with extreme obesity had a significantly younger age of onset of obesity, were significantly heavier at all age ranges, reported significantly more weight gain with their first pregnancy, and had significantly heavier parents and siblings as compared with less obese patients. There were no significant differences between groups with respect to weight gain during second pregnancies or postpartum weight retention. Robust test-retest correlations were obtained for the weight history items on the WALI.
Patients with extreme obesity report more indicators of a genetic predisposition to obesity as compared with less obese patients. The WALI appears to be a reliable instrument for the assessment of weight history in obese patients.
描述极度肥胖或III级肥胖（体重指数[BMI]≥40kg/m²）女性的体重史，并与I-II级肥胖（BMI<40kg/m²）女性样本进行比较，同时提供一种评估体重史的临床工具的可靠性数据。
149名寻求减肥手术的极度肥胖女性患者和90名寻求行为治疗的I-II级肥胖女性完成了体重与生活方式量表（WALI），这是一种自我报告工具，用于评估肥胖发病年龄、不同年龄段的最大体重、家族体重史以及与妊娠相关的体重变化。通过在初次就诊时以及1至2周后的另一次治疗前就诊时，对I-II级肥胖参与者的一个子样本（n = 58）进行WALI测试，获得重测可靠性数据。
与肥胖程度较低的患者相比，极度肥胖患者的肥胖发病年龄显著更小，在所有年龄段体重都显著更重，首次怀孕时体重增加显著更多，且父母和兄弟姐妹体重也显著更重。两组在第二次怀孕期间的体重增加或产后体重滞留方面无显著差异。WALI上的体重史项目获得了稳健的重测相关性。
与肥胖程度较低的患者相比，极度肥胖患者报告了更多肥胖遗传易感性指标。WALI似乎是评估肥胖患者体重史的可靠工具。
