Constipation is a common problem in children with cerebral palsy and may negatively affect daily activities, quality of life, and family well-being. Several factors such as nutrition, physical activity level, functional status, and psychological condition of the caregiver may be associated with constipation in this population.

The aim of this study is to investigate the presence and severity of constipation in children with cerebral palsy and to examine the factors that may be related to constipation, including dietary intake, fluid consumption, physical activity level, functional status, and caregiver psychological status.

This study is an observational cross-sectional study including children with cerebral palsy aged 4-18 years and their caregivers. Data will be collected using questionnaires, clinical classification systems, bowel diaries, nutrition records, and psychological scales. No intervention will be applied to participants.
