Weight-loss intervention adherence levels and factors promoting adherence
Background: Adhering to weight-loss interventions is difficult for many people. The majority of those who are overweight or
obese and attempt to lose weight are simply not successful. The objectives of this study were 1) to quantify overall adherence
rates for various weight-loss interventions and 2) to provide pooled estimates for factors associated with improved adherence
to weight-loss interventions.
Methods: We performed a systematic literature review and meta-analysis of all studies published between January 2004 and
August 2015 that reviewed weight-loss intervention adherence.
Results: After applying inclusion and exclusion criteria and checking the methodological quality, 27 studies were included in
the meta-analysis. The overall adherence rate was 60.5% (95% confidence interval [CI] 53.6–67.2). The following three main
variables were found to impact adherence: 1) supervised attendance programs had higher adherence rates than those with
no supervision (RR= 1.65; 95% CI 1.54–1.77); 2) interventions that offered social support had higher adherence than those
without social support (RR= 1.29; 95% CI 1.24–1.34); and 3) dietary intervention alone had higher adherence than exercise
programs alone (RR= 1.27; 95% CI 1.19–1.35).
Conclusion: A substantial proportion of people do not adhere to weight-loss interventions. Programs supervising attendance,
offering social support, and focusing on dietary modification have better adherence than interventions not supervising
attendance, not offering social support, and focusing exclusively on exercise.
