An interventional study of Sunlight Exposure in Cerebral Palsy, sponsored by Universitas Indonesia. Completed at 1 site in Indonesia. Open to participants aged 1 Year to 5 Years. Per ClinicalTrials.gov, last updated 2026-09-18.
Sponsored by Universitas Indonesia · Not applicable, Interventional, and Supportive care
The goal of this clinical trial is to learn the effect of sunlight exposure on serum vitamin D levels in children aged 1-5 years with cerebral palsy. This study also aims to assess the effect of sunlight exposure on the incidence of acute respiratory tract infections and to evaluate the safety of the intervention.
The main questions it aims to answer are:
Participants will:
This study evaluates the effect of sunlight exposure for 8 weeks in increasing serum vitamin D levels among children with cerebral palsy. Children with cerebral palsy have a high risk of vitamin D deficiency due to limited mobility, inadequate nutritional intake, and the use of antiepileptic medications that may interfere with vitamin D metabolism. Sunlight exposure is a natural and accessible source of vitamin D.
Eligible participants are children with clinically confirmed cerebral palsy. Children with cerebral palsy who meet the eligibility criteria will be recruited from the Pediatric Clinic and Pediatric Inpatient Unit of Dr. Cipto Mangunkusumo National General Hospital, Jakarta. Children with chronic liver or kidney disease, contraindications to direct sunlight exposure, inability to follow the intervention schedule, severe malnutrition, or baseline vitamin D deficiency (\<20 ng/mL) will not be included in the study.
Vitamin D status will be assessed by measuring serum vitamin D concentration. The assessment will be performed through blood sampling conducted by trained healthcare personnel according to standard medical procedures.
During the study, parents or caregivers will be instructed to monitor the child's condition, including signs of discomfort during sunlight exposure such as overheating, skin redness, persistent crying, or other complaints. If participants are unable to complete the exposure in one session due to discomfort, the exposure may be performed gradually within the same day while maintaining the required total duration.
Researchers will monitor adherence to the intervention through scheduled video calls to ensure that the sunlight exposure procedure is performed according to the study protocol. Dietary intake assessment will be performed using food recall and analyzed by the research team.
Exclusion Criteria:
Receive sunlight exposure for 10 minutes, three times per week with approximately 30% of body surface area exposed.
Behavioral: Sunlight Exposure
Participants will continue their usual sunlight exposure habits without a structured sunlight exposure program for 8 weeks.
Participants will receive sunlight exposure for 10 minutes, three times per week between 11:00 AM-1:00 PM Western Indonesia Time (WIB) for 8 weeks, with approximately 30% of body surface area exposed.
Serum vitamin D level
Change in serum vitamin D concentration from baseline to week 8 after sunlight exposure intervention.
Time frame: At the beginning from enrollment and at the end of intervention (after 8 weeks)
Incidence of acute respiratory tract infections (ARTIs)
Occurrence of acute respiratory tract infection episodes during the 8-week study period.
Time frame: Throughout the 8-week study period
Acute adverse effects related to sunlight exposure
Occurrence of acute adverse effects during the intervention, including skin redness, discomfort, overheating, or other reported complaints.
Time frame: Throughout the 8-week study period
Plan to share: No — Individual participant data will not be shared with other researchers. The study does not plan to make individual participant data available outside the research team. All research data will be kept confidential, stored securely, and accessed only by authorized members of the research team in accordance with applicable ethical and confidentiality requirements
