Health behaviour change is a cornerstone in the management of obesity, and data on health behaviours, intentions and barriers to change would be useful to inform the development of interventions. The aim of this study was to describe these variables in individuals with obesity, and to compare obesity classes. The study obtained data from the Canadian Community Health Survey 2011-2012 including 5614 adults with body mass index (BMI) ≥30 kg m . The majority of participants reported eating four or more fruits and vegetables daily (65.3% [95% confidence interval {CI}: 64.1-66.6]), being a regular drinker (59.6% [95% CI: 58.4-61.0]) and inactive (58.0% [95% CI: 56.7-59.3]). About 84% of participants answered they should do and/or intend to do something in the next year to improve their health, with increasing exercise being the most reported choice (69.2% [95% CI: 67.1-71.5]). Among the 58.0% (95% CI: 55.9-60.2) of participants facing barriers to change, the lack of willpower was the most reported (37.0% [95% CI: 34.2-39.7]). No difference between classes for intention to change and barriers were found. Comorbidities were the most important factor explaining several health behaviours and barriers to change. The vast majority of participants, regardless of the severity of obesity, know they should do and also want to do something to improve their health, but faced a lack of willpower. Thus, the most important thing to consider during an obesity intervention is the lack of motivation to modify health behaviours and beyond BMI, the presence of comorbidities.
健康行为改变是肥胖管理的基石，有关健康行为、改变意图和障碍的数据将有助于为干预措施的制定提供信息。本研究的目的是描述肥胖个体的这些变量，并比较肥胖类别。该研究从2011 - 2012年加拿大社区健康调查中获取数据，包括5614名体重指数（BMI）≥30 kg/m²的成年人。大多数参与者报告称每天食用四种或更多水果和蔬菜（65.3% [95%置信区间{CI}：64.1 - 66.6]），是经常饮酒者（59.6% [95% CI：58.4 - 61.0]）且不运动（58.0% [95% CI：56.7 - 59.3]）。约84%的参与者回答他们应该在明年做和/或打算做些事情来改善健康，增加运动量是最常被提及的选择（69.2% [95% CI：67.1 - 71.5]）。在面临改变障碍的58.0%（95% CI：55.9 - 60.2）的参与者中，意志力缺乏是最常被提及的（37.0% [95% CI：34.2 - 39.7]）。在改变意图和障碍方面，各肥胖类别之间未发现差异。合并症是解释多种健康行为和改变障碍的最重要因素。绝大多数参与者，无论肥胖严重程度如何，都知道他们应该并也想做些事情来改善健康，但面临意志力缺乏的问题。因此，在肥胖干预过程中要考虑的最重要的事情是缺乏改变健康行为的动力，以及除BMI之外合并症的存在。
