Changes in psychosocial health during a 7-week paediatric weight management program

Youth with obesity are at increased risk of psychosocial symptoms; however, little is known regarding the impact of paediatric weight management (PWM) on psychosocial health. The aim of the study was to investigate changes in psychosocial health among children who completed a 7-week PWM program. Participants aged 5 to 16 years with a BMI ≥85th percentile completed a 7-week, family-centred PWM program focused on health behaviour education, exercise and mentored goal setting. The Paediatric Symptom Checklist (PSC) was assessed via parent report to evaluate psychosocial symptoms before and after the program, and subscales were calculated for internalizing (PSC-IS), externalizing (PSC-ES) and attention symptoms (PSC-AS). At baseline, positive screen rates for psychosocial symptoms among the 317 patients included 16.1% for PSC, 14.1% for PSC-ES, 18.6% for PSC-IS and 12.3% for PSC-AS. Among program completers, total PSC scores improved in those with normal (p = 0.010) and elevated p < .001 psychosocial symptoms at baseline. Youth with positive screens for elevated PSC subscales improved their subscale scores, on average, and the majority reduced scores to below elevated levels for PSC (54.2%), PSC-ES (64.7%), PSC-IS (78.3%) and PSC-AS (64.7%). Improvements in PSC remained significant after adjusting for BMI changes during treatment, but BMI differed across PSC-change groups, including BMI increases among participants with PSC deterioration (0.33 ± 0.64 kg m^-2 ) (P = 0.035) and BMI decreases among patients with no reliable PSC change (-0.26 ± 1.04 kg m^-2 ) (P = 0.038) or reliable PSC improvement (-0.22 ± 0.74 kg m^-2 ) (P = 0.025). Youth with positive screens for psychosocial symptoms can improve emotional and behavioural functioning during short-term PWM. Future research is needed to elucidate mechanisms and long-term outcome durability.
