Brief Summary

Antipsychotic medications are commonly prescribed in children and adults with ASD (Curtin, Jojic & Bandini, 2014). But weight gain has been known to be one of the less desirable effects of these medications, increasing one's risk for overweight and obesity. Based on experience in Holland Bloorview's Nutrition Clinic, working with a dietitian to follow specific dietary advice, such as having more protein while keeping the amount of calories the same, may be a possible and useful way to limit weight gain.

This study's objective is to evaluate the feasibility (study designs, methods, processes) and acceptability (client/family satisfaction, perceived effectiveness) of a controlled energy diet with elevated protein intake in children and youth with ASD who are currently taking prescribed atypical antipsychotic medication.

Detailed Description

The use of psychotropic medication in children and youth with Autism Spectrum Disorder (ASD) to treat symptoms of aggression, irritability and related behavioural problems has become increasingly common in recent years. Data obtained from clinical and nationally representative populations of children demonstrate that approximately 30%-60% of children with ASD are prescribed at least one psychotropic medication, and 10% are prescribed more than three medications at the same time (Curtin, Jojic & Bandini, 2014).

Weight gain, which is one of the harmful effects of psychotropic medication, is likely one of the most understood risk factors for obesity in children and adults with ASD. In a systematic review and meta-analysis of double-blinded, randomized, controlled trials studying the metabolic adverse effects of atypical antipsychotics in children and adolescents under 18 years of age, risperidone, olanzapine and aripiprazole were associated with statistically significant weight gain compared with placebo (Almandil et al., 2013). Similar findings were reported from a review of literature, using PubMed, on weight gain and increase of BMI among children and adolescents (0-18 years old) treated with antipsychotic medications (Martinez-Ortega et al., 2013).

Although clinical trials with different agents have been conducted in an attempt to address weight gain in individuals on psychotropic medications, no established treatments or preventative measures have been developed to combat psychotropic-induced weight gain (PIWG) to date (Curtin, Jojic & Bandini, 2014). A review of published literature using PubMed yielded limited and mixed results for using Metformin as the intervention for the treatment in combating PIWG (Anagostou et al., 2016; Handen et al., 2017). Based on clinical experience in Holland Bloorview's Nutrition Clinic, controlled energy intake combined with elevated protein intake (CEEP) may represent an effective and practical strategy for limiting weight gain.

Potential beneficial outcomes associated with protein ingestion include: a) increased satiety, which is being satisfactorily full - protein generally increases satiety to a greater extent than carbohydrate or fat and may facilitate a reduction in energy consumption; b) increased thermogenesis, which is the production of heat in the body - higher protein diets are associated with an increase in thermogenesis, which also influences satiety and increases energy expenditure; and c) maintenance or growth of fat-free mass (muscle) - an elevated protein diet may provide an increase effect on muscle protein synthesis in some individuals, favouring the retention of lean muscle mass while improving metabolic profile (Paddon-Jones et al., 2018).

This study's primary objective is to evaluate the feasibility (study designs, methods, processes) and acceptability (client/family satisfaction, perceived effectiveness) of a controlled energy diet with elevated protein intake in children and youth with ASD who are currently taking prescribed atypical antipsychotic medication.

Children and youth, ages 6-17 years old, with ASD (n=10) on atypical antipsychotic medication will be exposed to specific nutrition recommendations involving CEEP for ten consecutive weeks. Each participant and parent/guardian will work collaboratively with the RD/RA to formulate strategies to slowly increase protein intake in the range of 20-30% of total caloric intake and ensure consistent energy intake. Data will be collected through food records, anthropometric measurements and informal post-intervention interviews to measure the feasibility and acceptability of the study processes and elevated protein dietary changes.

• Blinding Strategy: NONE

Study Groups

Controlled energy intake with elevated protein intake

Dietary intervention - Participants will be counseled to elevate protein and control energy intake for ten consecutive weeks.

Group Type: OTHER

Controlled energy diet with elevated protein intake

Intervention Type: OTHER

Participants will be counseled to elevate protein and control energy intake for ten consecutive weeks. Protein intake will be increased in the range of 20-30% of total daily caloric intake. Each participant's diet will also be modified to implement controlled energy intake. Controlled energy intake will be defined as being isocaloric with the participant's current dietary intake.
