Abstract

Background

A sleeve gastrectomy (SG) is a lifelong treatment that improves health and better outcomes are associated with follow-up. However, there is lack of access or high attrition to aftercare. This potentially contributes to sub-optimal dietary intake and a lack of evidence for nutrition interventions. The present study assessed the feasibility and preliminary efficacy of a nutrition intervention to improve diet quality in Australian adults living with a SG.

Methods

Adults (n = 96) post-SG were recruited into a cross-sectional diet quality study, with 68 eligible for randomisation to an intervention or wait-list control group. Over 10 weeks, a Facebook group was used to post daily nutrition education. Feasibility outcomes included participant recruitment, engagement, retention and acceptability. Preliminary efficacy was assessed using change in Australian Recommended Food Score (ARFS). Linear mixed models were used to measure differences in mean outcome between the experimental groups over time.

Results

Sixty-eight participants (97% female) aged 48.2 ± 9.8 years, body mass index 33.1 ± 5.8 kg/m², and mean ± SD ARFS 39 ± 9 points were randomised to the intervention, with 66% retention at 10 weeks. At follow-up, diet quality increased for the intervention group (mean ARFS, 95% confidence interval = 0.2 [−1.5 to 1.9]) and decreased for the control group (mean ARFS, 95% confidence interval= −2.0 [−5.2 to 1.2]) with no between group difference (p = 0.2). Participants (n = 30) rated the intervention positively.

Conclusions

Recruiting and retaining adults post-SG into a nutrition intervention is feasible. Low-cost recruitment attracted strong interest from women to identify greater support to know what to eat following SG. A future fully powered trial to assess intervention efficacy is warranted.

针对袖状胃切除术患者的在线营养教育干预的可行性和初步疗效：随机对照试验。

背景：袖带胃切除术（SG）是一种可改善健康状况的终生治疗方法，其更好的效果与后续治疗有关。然而，人们缺乏接受术后护理的机会，或术后护理的流失率很高。这可能会导致饮食摄入量低于最佳水平，而且缺乏营养干预的证据。本研究评估了营养干预的可行性和初步效果，以改善澳大利亚成年 SG 患者的饮食质量：一项横断面饮食质量研究招募了 SG 后成年人（n = 96），其中 68 人符合随机分配到干预组或候补对照组的条件。在为期 10 周的时间里，Facebook 小组每天都会发布营养教育信息。可行性结果包括参与者招募、参与、保留和可接受性。初步效果通过澳大利亚推荐食物评分（ARFS）的变化进行评估。线性混合模型用于测量实验组之间随着时间推移平均结果的差异：68 名参与者（97% 为女性）被随机分配到干预组，年龄为 48.2 ± 9.8 岁，体重指数为 33.1 ± 5.8 kg/m2，平均± SD ARFS 为 39 ± 9 分，其中 66% 的参与者在 10 周后继续接受干预。在随访中，干预组的饮食质量有所提高（平均 ARFS，95% 置信区间 = 0.2 [-1.5 至 1.9]），对照组的饮食质量有所下降（平均 ARFS，95% 置信区间 = -2.0 [-5.2 至 1.2]），组间无差异（P = 0.2）。参与者（n = 30）对干预措施给予了积极评价：结论：招募并留住 SG 后成年人参与营养干预是可行的。低成本招募吸引了女性的强烈兴趣，她们希望获得更多支持，以了解 SG 后的饮食。未来有必要开展一项全面的试验来评估干预效果。

期刊介绍： Journal of Human Nutrition and Dietetics is an international peer-reviewed journal publishing papers in applied nutrition and dietetics. Papers are therefore welcomed on: - Clinical nutrition and the practice of therapeutic dietetics - Clinical and professional guidelines - Public health nutrition and nutritional epidemiology - Dietary surveys and dietary assessment methodology - Health promotion and intervention studies and their effectiveness - Obesity, weight control and body composition - Research on psychological determinants of healthy and unhealthy eating behaviour. Focus can for example be on attitudes, brain correlates of food reward processing, social influences, impulsivity, cognitive control, cognitive processes, dieting, psychological treatments. - Appetite, Food intake and nutritional status - Nutrigenomics and molecular nutrition - The journal does not publish animal research The journal is published in an online-only format. No printed issue of this title will be produced but authors will still be able to order offprints of their own articles.
