Effective use of health technology may offer a scalable solution to the obesity pandemic. Online digital programmes provide a convenient and flexible way for more people to access regular support. This service evaluation aims to determine whether adults accessing an online weight management programme via a national campaign are successful in losing weight.Data was analysed for adults registering with Slimming World's online programme using a discounted membership offered as part of PHE's 'Better Health' campaign between July and December 2020. Last-weight carried forward was used to calculate weight outcomes for participants who had the opportunity to complete 12-weeks and recorded ≥ one weight besides baseline. Engagement was determined using number of online weekly weights recorded with high engagers having weight data for ≥ 9 occasions. Socioeconomic status was assessed using postcode data. Resubscription and uploaded weight data were used to determine numbers who continued beyond the offer period.Twenty-seven thousand two hundred forty-eight adults (5.3% males) with mean age 41.0 ± 11.4 years met inclusion criteria. Mean baseline BMI was 33.4 ± 6.8 kg/m (29.2% 30-34.9, 18.3% 35-39.9 and 15.1% > 40 kg/m). Mean weight loss at 12 weeks was 2.7 (± 3) kg representing a mean loss of 3% (± 3.1) body weight with 42.3% achieving ≥ 3% and 22.1% weight loss ≥ 5%. Median number of weigh-ins was six. Men had greater weight losses compared to women (p < 0.001). High engagers, both men and women, achieved greater weight losses (p < 0.001). Absolute weight loss was associated with joining BMI (r = -0.15, p < 0.001) but for % weight change only small differences were seen (max effect size = 0.03) with no differences in weight change for high engagers between different baseline BMI categories (p > 0.05). 30.9% were in the lowest two IMD quintiles and absolute and percentage weight change did not differ across deprivation quintiles (p > 0.05). 34.9% continued to access the online support after the offer period.This service evaluation shows that an online programme, offered as part of a national campaign, can offer effective support to a large number of people with different starting BMIs and from different socioeconomic backgrounds. An increased level of engagement leads to better weight losses.
有效利用卫生技术可能为肥胖流行提供一种可扩展的解决方案。在线数字计划为更多人提供了定期接受支持的便捷和灵活方式。本服务评估旨在确定通过全国性运动参与在线体重管理计划的成年人是否能够成功减肥。
2020 年 7 月至 12 月期间，使用 PHE 的“更健康”运动提供的折扣会员资格，对在 Slimming World 的在线计划中注册的成年人的数据进行了分析。对有机会完成 12 周并记录除基线外的至少一次体重的参与者，使用先前的体重来计算体重结果。使用记录的在线每周体重次数来确定高参与度者的参与度，高参与度者的体重数据记录次数不少于 9 次。社会经济地位使用邮政编码数据进行评估。续展和上传的体重数据用于确定在优惠期结束后继续使用的人数。
符合纳入标准的 27248 名成年人（5.3%为男性），平均年龄为 41.0±11.4 岁。平均基线 BMI 为 33.4±6.8kg/m（29.2%为 30-34.9kg/m，18.3%为 35-39.9kg/m，15.1%为>40kg/m）。12 周时的平均体重减轻量为 2.7（±3）kg，代表体重减轻 3%（±3.1），42.3%的人减轻≥3%，22.1%的人减轻≥5%。中位数体重记录次数为六次。与女性相比，男性的体重减轻更多（p<0.001）。高参与度者（男性和女性）的体重减轻更多（p<0.001）。绝对体重减轻与加入 BMI 相关（r=-0.15，p<0.001），但对于体重减轻百分比，仅观察到较小的差异（最大效应量=0.03），高参与度者在不同的基线 BMI 类别之间体重减轻无差异（p>0.05）。30.9%的人处于 IMD 的前两个五分位数，绝对和百分比体重减轻在贫困五分位数之间没有差异（p>0.05）。34.9%的人在优惠期后继续使用在线支持。
本服务评估表明，作为全国性运动的一部分提供的在线计划可以为具有不同起始 BMI 和不同社会经济背景的大量人群提供有效的支持。更高的参与度会导致更好的体重减轻。
