Objectives:
To examine children's wait time to access a multidisciplinary, tertiary-level weight management clinic and assess anthropometric changes from time of referral to baseline assessment.
Method:
A retrospective medical record review was completed of children (5 to 17 years) enrolled in a multidisciplinary, tertiary-level paediatric weight management clinic from 2006 to 2015. Children's demographic and anthropometric data from their referral to and baseline assessment at the clinic were retrieved from medical records. Based on changes in body mass index (BMI) z-score from the time of referral to baseline assessment, children were categorized as decreasers (>0.05 unit decrease), increasers (>0.05 unit increase) or stabilizers (-0.05 to 0.05 unit change). The proportion of children with a ≥0.25 unit BMI z-score reduction was calculated. Analysis of variance and chi-squared tests were performed.
Results:
Children (n=400) were 11.7 ± 2.9 years old at the time of referral, 52.8% (n=211) female, and had an average wait time of 4.5 ± 3.9 months. By 3 and 6 months postreferral, 44.0% (n=176) and 80.8% (n=323), respectively, had attended baseline assessments. Based on BMI z-score change, children were classified as decreasers (n=183; 45.8%), increasers (n=118; 29.5%) or stabilizers (n=99; 24.8%). One-fifth of children (n=86; 21.5%) experienced a BMI z-score reduction ≥0.25 units, a subgroup that was younger, had a higher BMI z-score at referral, and had a longer wait time between referral and baseline assessment (all P<0.05).
Conclusions:
Most children who enrolled in paediatric weight management initiated treatment within six months and experienced a modest decrease or stabilization in BMI z-score during their wait time.
