Abstract

Introduction: Weight loss through behavioural weight management interventions can have important health benefits for people with obesity. However, to maximise the health benefits, weight loss must be maintained. Evidence suggests that behavioural weight loss interventions do not exacerbate inequalities in the short term. However, no study has yet considered whether inequalities exist in long-term weight change following intervention. We aimed to investigate if there are inequalities in weight change following weight loss intervention.

Methods: We conducted a cohort analysis of data from the Weight Loss Referrals for Adults in Primary Care (WRAP) trial (N = 1,267). WRAP randomised participants to receive a brief intervention information booklet or vouchers for 12-weeks or 52-weeks of WW (formerly WeightWatchers) and followed them for 5 years. Multiple linear regression estimated the association between exposures (indicators of inequality) and outcomes (change in weight between 1- and 5-years). Each model was adjusted for the intervention group, baseline weight, weight change between baseline and 1-year, research centre, and source of the 5-year weight data.

Results: Of the 1,267 participants in WRAP, 708 had weight change data available. Mean weight change between 1- and 5-years was +3.30 kg (SD 9.10 kg). A 1 year difference in age at baseline was associated with weight change of 0.11 kg ((95% CI 0.06, 0.16), p < 0.001). We did not find evidence of associations between ethnicity, gender, education, indices of multiple deprivation, household income, or other family members participating in a weight loss programme and weight change.

Conclusion: Except for age, we did not find evidence of inequalities in weight change following a behavioural intervention. Findings further support the use of behavioural weight management interventions as part of a systems-wide approach to improving population health.

行为减肥干预后不平等指标与体重变化之间的关系。

导言:通过行为体重管理干预措施减轻体重对肥胖患者的健康有重要益处。然而，为了最大限度地提高健康效益，必须保持减肥。有证据表明，行为减肥干预措施在短期内不会加剧不平等。然而，目前还没有研究考虑干预后的长期体重变化是否存在不平等。我们的目的是调查减肥干预后体重变化是否存在不平等。方法:我们对来自初级保健成人减肥转诊(WRAP)试验(N = 1,267)的数据进行了队列分析。WRAP随机安排参与者接受简短的干预信息小册子或12周或52周的WW(以前的WeightWatchers)优惠券，并随访5年。多元线性回归估计暴露(不平等指标)与结果(1- 5年体重变化)之间的关联。每个模型都针对干预组、基线体重、基线与1年之间的体重变化、研究中心和5年体重数据的来源进行调整。结果:在WRAP的1267名参与者中，708人有体重变化数据。1- 5年的平均体重变化为+3.30 kg (SD 9.10 kg)。基线年龄相差1岁与体重变化0.11 kg相关(95% CI 0.06, 0.16)， p < 0.001)。我们没有发现种族、性别、教育、多重剥夺指数、家庭收入或参与减肥计划的其他家庭成员与体重变化之间存在关联的证据。结论:除年龄外，我们没有发现行为干预后体重变化不平等的证据。研究结果进一步支持将行为体重管理干预措施作为改善人口健康的全系统方法的一部分。

期刊介绍： ''Obesity Facts'' publishes articles covering all aspects of obesity, in particular epidemiology, etiology and pathogenesis, treatment, and the prevention of adiposity. As obesity is related to many disease processes, the journal is also dedicated to all topics pertaining to comorbidity and covers psychological and sociocultural aspects as well as influences of nutrition and exercise on body weight. The editors carefully select papers to present only the most recent findings in clinical practice and research. All professionals concerned with obesity issues will find this journal a most valuable update to keep them abreast of the latest scientific developments.
