Abstract

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.
