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.
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.
Sixty-eight participants (97% female) aged 48.2 ± 9.8 years, body mass index 33.1 ± 5.8 kg/m, 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.
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.
袖状胃切除术（SG）是一种终身治疗方法，可改善健康状况，并且与随访相关的更好结果。但是，获得后续护理的机会有限或随访率高。这可能导致饮食摄入不足和缺乏营养干预措施的证据。本研究评估了一种营养干预措施改善澳大利亚接受 SG 治疗的成年人饮食质量的可行性和初步疗效。
招募 SG 后成年人（n=96）进行横断面饮食质量研究，其中 68 名符合随机分配到干预组或等待名单对照组的条件。在 10 周内，使用 Facebook 群组每天发布营养教育。可行性结果包括参与者招募、参与度、保留率和可接受性。初步疗效通过澳大利亚推荐食物评分（ARFS）的变化来评估。使用线性混合模型测量实验组之间随时间的平均结果差异。
68 名参与者（97%女性）年龄 48.2±9.8 岁，体重指数 33.1±5.8kg/m，平均 ARFS±SD 为 39±9 分，随机分配至干预组，10 周时保留率为 66%。随访时，干预组的饮食质量增加（平均 ARFS，95%置信区间=0.2[-1.5 至 1.9]），对照组的饮食质量下降（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）对干预措施评价积极。
招募和保留 SG 后的成年人参加营养干预是可行的。低成本的招募吸引了女性的强烈兴趣，以确定在接受 SG 后需要更多的支持来了解该吃什么。需要进行一项未来的充分有效的试验来评估干预的疗效。
