Associations Between Hyperphagia, Symptoms of Sleep Breathing Disorder, Behaviour Difficulties and Caregiver Well-Being in Prader-Willi Syndrome: A Preliminary Study.
In Prader-Willi syndrome, child sleep-breathing problems and social difficulties correlate with poorer caregiver mental health, while growth-hormone therapy correlates with better caregiver well-being.
01Research in Context
What this study did
Klusek et al. (2022) looked at the families in the U.S. Prader-Willi syndrome registry.
Parents filled out four short surveys about child sleep-breathing, mood, social skills, and their own stress.
The team also noted which kids were on growth-hormone shots.
What they found
Children with louder snoring or gasping had more tantrums and social slips.
Those same kids had parents who scored highest on stress, anxiety, and sadness.
Families using growth-hormone therapy reported the calmest, best-rested parents.
How this fits with other research
Chu et al. (2009) saw the same sleep-stress loop in mixed developmental disabilities.
Rana et al. (2024) later repeated the pattern in cerebral palsy, showing the link is not unique to PWS.
Rzepecka et al. (2011) and Einfeld et al. (1996) only looked at how poor sleep fuels child behavior, not parent fallout—Jessica’s team connects the final dot to caregiver well-being.
Why it matters
If you serve a child with PWS, screen for snoring and apnea first. Treating sleep can lower tantrums and lift parent morale faster than starting a behavior plan alone. Share growth-hormone data with medical partners—it may be an easy win for the whole family system.

03Original abstract
Prader-Willi syndrome (PWS) is a rare genetic disorder characterised by neurodevelopmental delays, hyperphagia, difficulties with social communication and challenging behaviours. Individuals require intensive supervision from caregivers which may negatively affect caregiver quality of life. This study used data collected in the Australasian PWS Registry (n = 50, mean age 11.2 years) to evaluate associations between child behaviours and caregiver mental well-being. Symptoms of sleep-related breathing disorder, child depression and social difficulties were associated with poorer caregiver mental and physical well-being. Growth hormone therapy use was associated with better caregiver mental and physical well-being. Optimising management of problematic behaviours and sleep disturbances have the potential to support caregivers who are the most vital network of support for individuals affected by PWS.
