To evaluate the preliminary efficacy, feasibility and acceptability of the 3-month Body Balance Beyond (BBB) online program among Australian women with overweight/obesity and recent gestational diabetes mellitus.
Women were randomised into either: 1) High Personalisation (HP) (access to 'BBB' website, video coaching sessions, text message support); 2) Medium Personalisation (MP) (website and text message support); or 3) Low Personalisation (LP) (website only). Generalised linear mixed models were used to evaluate preliminary efficacy, weight, diet quality, physical activity levels, self-efficacy and quality of life (QoL) at baseline and 3-months. Feasibility was assessed by recruitment and retention metrics and acceptability determined via online process evaluation survey at 3-months.
Eighty three women were randomised, with 76 completing the study. Self-efficacy scores showed significant improvements in confidence to resist eating in a variety of situations from baseline to 3-months in HP compared to MP and LP groups (P=.03). The difference in mean QoL scores favoured the HP compared to MP and LP groups (P=.03). Half of the women (HP n=17[81%], MP n=12[75%], LP n=9[56%]) lost weight at 3-months. No significant group-by-time effect were reported for other outcomes. Two-thirds of women in the HP group were satisfied with the program overall and 86% would recommend it to others, compared with 25% and 44% in the MP group, and 14% and 36% in the LP group, respectively.
Video coaching sessions were associated with improvements in QoL scores and self-efficacy, however further refinement of the BBB website and text messages support could improve program acceptability.

评估澳大利亚超重/肥胖且近期患有妊娠期糖尿病的女性参与为期 3 个月的 Body Balance Beyond（BBB）在线项目的初步疗效、可行性和可接受性。
将女性随机分为三组：1）高个性化组（HP）（可访问“BBB”网站、视频教练课程、短信支持）；2）中个性化组（MP）（网站和短信支持）；3）低个性化组（LP）（仅网站）。使用广义线性混合模型评估基线和 3 个月时的初步疗效、体重、饮食质量、身体活动水平、自我效能和生活质量（QoL）。通过招募和保留指标评估可行性，并通过 3 个月时的在线过程评估调查确定可接受性。
83 名女性被随机分配，其中 76 名完成了研究。与 MP 和 LP 组相比，HP 组在抵抗各种情况下进食的信心方面，自我效能评分在基线到 3 个月时显示出显著改善（P=.03）。与 MP 和 LP 组相比，HP 组的 QoL 评分差异更有利于改善（P=.03）。一半的女性（HP n=17[81%]，MP n=12[75%]，LP n=9[56%]）在 3 个月时体重减轻。未报告其他结果的组间时间效应。HP 组中有三分之二的女性对该计划总体满意，86%的人会向他人推荐，而 MP 组和 LP 组分别为 25%和 44%、14%和 36%。
视频教练课程与 QoL 评分和自我效能的提高有关，但是进一步改进 BBB 网站和短信支持可以提高计划的可接受性。
