    Scaled interventions are required to address levels of overweight and obesity and reduce health inequalities. Little data is available on the effectiveness of community weight management programmes for participants self-selecting to attend across different socio-economic backgrounds. This analysis investigates 3, 6, and 12-month outcomes of adults joining a real-life community weight management programme. Weight, attendance and Indices of Multiple Deprivation (IMD) data from all fee-paying adults joining Slimming World in 2016 were collated. Data were analysed using descriptive and inferential statistics to determine predictors of weight loss. Mean BMI of 1 094 676 adults (7.6% male) was 33.0 ± 6.4 kg/m. Mean % weight change at 3, 6, and 12 months was -5.0% ± 3.6%, -5.9% ± 5.2%, and -6.0% ± 5.8%. Those attending 75% sessions achieved greater weight loss with mean weight losses at 3, 6, and 12-months of 7.7% ± 3.3%, 11.3% ± 5.2%, and 14.1% ± 7.5%, respectively. Effect sizes from comparison of weight change between deprivation deciles were negligible, with similar outcomes in the most and least deprived deciles at 12-months (-5.7% ± 5.9% vs. -6.2% ± 5.9%). This service evaluation of more than 1 million adults attending a community weight management programme found they were able to achieve and/or maintain an average 6% weight loss at 12 months, with high attenders achieving >14% loss. Men and those with higher levels of deprivation were accessing the support and achieving significant weight losses. Slimming World as a real-life, scalable weight management programme is well placed to help adults manage their weight and address health inequalities.

    A Service Evaluation of More Than 27 000 Adults Referred to a Community Weight Management Program: 24-Month Outcomes
    (Sage, 2024-10-21) Toon, Josef; Bennett, Sarah-Elizabeth; Lavin, Jacquie; Pallister, Carolyn; Avery, Amanda
    Background: Obesity has a significant impact on healthcare resources with limited accessible support available through the NHS. This service evaluation determines 24-month efficacy of referral to an open-group behavioral program by BMI category and socioeconomic status. Methods: This retrospective, longitudinal study examined weight outcomes of adults living in England referred by healthcare professionals to Slimming World during 2016 who recorded at least 1 weight change. Primary outcome was % weight change at 3, 6, 12, and 24 months. Socioeconomic status was measured using the Index of Multiple Deprivation (IMD). Data from a post-referral questionnaire investigated self-reported changes in dietary and activity behaviors. Results: Twenty-seven thousand five hundred sixty (15.6% male) records were analyzed. Mean (SD) age and BMI on joining were 48.6 (14.80) years and 37.1 (6.31) kg/m2; 91.7% had a BMI > 30 kg/m2. Mean (SD) % weight change was −5.6 (3.79), −7.1 (5.71), −7.5 (6.88), and −7.3 (6.88) at 3, 6, 12, and 24-months, respectively. At 24- months, differences in weight loss between BMI category were significant, ranging from 0.29% (35-<40 vs 40+) to 1.33% (25-<30 vs 40+). For IMD quintile only comparisons against Q1 and Q2 were significant, ranging between 0.36% (Q2 vs Q3) to 0.94% (Q1 vs Q5). Five thousand eight hundred sixty-two (21.2%) completed the post-referral questionnaire. There were no BMI category effects on dietary behaviors but changes in physical activity behaviors were lower within the higher categories albeit effect sizes were small (all ges < 0.001). IMD quintile influenced changes for sugary drinks, watching TV and avoiding moderate activity although effect sizes were small (all ges < 0.01). Conclusion: Following 12-week referral to a commercial weight management organization, a mean weight loss of over 7% was reported at 24-months. Adults with higher BMIs and a greater level of deprivation can benefit from the practical support offered as part of the referral, supporting weight loss and weight loss maintenance albeit with some inequality.

    Impact of COVID-19 on health-related behaviours, well-being and weight management
    (Springer Nature, 2021-06-16) Avery, Amanda; Toon, Josef; Kent, Jennifer; Holloway, Laura; Lavin, Jacquie; Bennett, Sarah-Elizabeth
    Background Weight management is complex for people even in times of stability. Supporting individuals to develop strategies to maintain a healthier weight when there are additional life challenges may prevent relapse. This mixed-methods study describes the impact the COVID-19 restrictions had on adults engaged in weight management before and during the pandemic in order to determine helpful strategies. Methods Longitudinal data was captured from online surveys completed by Slimming World (SW) members 0–4 weeks after joining, October/November 2019, providing pre-joining and baseline (T0 & T1), 3- (T2) and 6- month (T3-during COVID-19) data. Representatives from the general population, not attending a weight management service, completed the same questionnaires providing cross-sectional control data. All weights are self-reported. For this study, questions assessing the impact of the COVID-19 challenges on health-related behaviours and well-being are included comparing responses at T0/T1, T2 & T3. Longitudinal data were analysed using repeated measures ANOVA and cross-sectional data, one-way independent ANOVAs to compare means. Comparisons between SW members and controls were determined using z-proportion tests. Qualitative data generated was thematically analysed using a six-step approach to produce the key emerging themes. Results 222 SW members completed all three surveys, achieving a weight loss of 7.7 ± 7.5%. They maintained positive health-related behaviour changes made since joining, including increased fruit and vegetables p<0.001, fewer sugary drinks p<0.001, cooking from scratch p<0.001) and increased activity levels p0.001). Despite COVID-19 restrictions, they were still reporting improvements in all behaviours and had healthier scores than the controls on all but alcohol intake, although still within guidelines. Qualitative data indicated that the situation created various challenges to managing weight with fresh foods harder to access, comfort eating, drinking more alcohol, eating more sugary foods and snacking through boredom. However, some reported having more free time enabling better planning, more time to cook from scratch and increased physical activity. Conclusions The findings highlight the value of peer, group and online support and guidance for individuals to develop sustainable behaviour changes and a level of resilience. These strategies can then be drawn upon enabling maintenance of lifestyle changes and management of weight even in challenging times.

    Weight loss outcomes achieved by adults accessing an online programme offered as part of Public Health England's 'Better Health' campaign.
    (Springer Nature, 2022-07-30) Toon, Josef; Geneva, Martina; Sharpe, Paul; Lavin, Jacquie; Bennett, Sarah; Avery, Amanda
    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.
