Aim
This systematic review explored the feasibility, acceptability and effect on health outcomes of weight‐neutral interventions in health improvement‐seeking young people with overweight/obesity.
Methods
Six databases were searched to March 2021 for health, but not weight, focused interventions (PROSPERO, CRD42020152671). Eligible studies recruited young people (10–24 years) with overweight/obesity. The studies were described using narrative synthesis, with numerical results summarised. The quality of included studies was assessed using the Joanna Briggs Institute critical appraisal tools.
Results
Six articles were included, representing three pilot studies. Study 1 (n = 37, 14–17 years) compared a 6‐week mindful eating program with single‐session lifestyle education; Study 2 (n = 35, 14–17 years) compared 12‐week weight‐neutral lifestyle education focused on intuitive eating and carbohydrate quality, with/without guided imagery; and Study 3 (n = 33, 12–17 years) compared a 6‐week mindfulness intervention with cognitive behavioural therapy in adolescents with depressive symptoms at risk of type 2 diabetes. All interventions explored feasibility (intervention group retention 57%–88%, attendance >80%) and reported interventions were acceptable. Studies 1 and 3 reported no change in mindfulness. Study 2 reported an increase (p < 0.05) in intuitive eating following weight‐neutral plus guided imagery (0.32 ± 0.36, Hawks' Scale, score 1–4), compared with weight‐neutral alone (0.15 ± 0.29). Study 1 reported decreased body mass index (p < 0.001) following mindful eating (−1.1 kg/m2), compared with single‐session lifestyle education (+0.7 kg/m2); Studies 2 and 3 found no change in body mass index or body mass index z‐score.
Conclusions
Weight‐neutral interventions may be feasible and acceptable in adolescents with overweight/obesity in the short term (≤12 weeks), but data are limited.
