PMID 34167389WHAT IT FOUND
Among 238 adults in a community diabetes prevention program, those who had already lost 5% weight by 6 months were more likely to meet that goal at 12 months if they attended at least 4 maintenance sessions.
Key findings
01Meeting the 5% weight loss goal at 6 months was associated with an odds ratio of 29.2 for meeting the 12-month goal.
02Attending at least 4 maintenance sessions was associated with greater odds of meeting the 12-month goal overall, odds ratio 6.0, but the significant association was only in participants who had already met the 6-month goal, odds ratio 11.4, not in those who had not, odds ratio 1.5.
03Medicare-eligible adults were more likely to meet the 12-month goal than adults younger than 65, 63.9% versus 33.1%.

What it does not show
This was a post hoc secondary analysis, not a trial designed to test whether maintenance attendance causes weight loss success. Attendance was very high, with 84% attending at least 4 maintenance sessions, so the study could not closely examine lower or more varied attendance levels. The sample came from community centers around Pittsburgh and was mostly female, non-Hispanic white, and more than half had at least a bachelor's degree, so results may not apply to more diverse populations. Only participants who attended at least 4 core sessions and had weight and attendance data were analyzed, so it says nothing about people who drop out early or miss much of the intervention. The original trials had different age eligibility and some demographic differences, and the analysis combined them, although a sensitivity analysis did not find a significant difference between trials. The intervention included many components, so the association with maintenance attendance cannot be separated from coaching, self-monitoring materials, pedometers, weighing, activity goals, and weight loss goals.
Declared interests
The trials were NIH-funded. No author conflict-of-interest statement is given.
The easy way to misread this
Do not conclude that maintenance sessions alone caused weight loss success. Participants also received coaching, handouts, self-monitoring logs, pedometers, weighing, physical activity goals, and weight loss goals, and this post hoc analysis cannot separate those components. Also, attending at least 4 maintenance sessions was significantly associated with 12-month success only among participants who had already met the 5% weight loss goal at 6 months. For participants who had not met the 6-month goal, the association was not significant.
