AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children aged 5 up to 18 years in South Africa who agree to take part and have a parent's permission. It measures blood pressure in children.
- Age
- From 5 years to under 18 years.
- Sex
- All sexes can join.
Main reasons for not taking part
- Children who cannot give informed consent or who have a language barrier
- Children who choose not to take part, even with a parent's permission
- Children who cannot follow study guidelines, for example because of drug, alcohol or tobacco use
- Children older than 18 years or younger than 5 years
The registry criteria, word for word
Show all 7 criteriaShow less
Who can take part
- All children between ages 5-<18 years
- All children with voluntary assent/consent and parent's permission
Who cannot take part
- randomly selected children who choose not to participate (lack of assent/consent), even if parent's permission was received,
- Children will be excluded from the analysis for the determination of normative reference values for blood pressure and anthropometry if taking certain concomitant medication(s) that may affect their blood pressure, or any underlying disease e.g., chronic kidney disease, chronic heart disease etc. that may raise blood pressure
- conditions that interfere with a patient's ability to follow study guidelines, e.g., the use of drugs, alcohol or tobacco products
- ages >18 years or under 5 years
- circumstances interfere with the participant's ability to give informed consent (diminished understanding or comprehension, or any language barriers that may pose potential risk in participation under false expectations)

About the trial
What the trial wants to find out
The Childhood Hypertension Consortium of South Africa (CHCSA) was established to foster relationships between the healthcare sector and schools through community engagement and outreach as well as contributing to the decolonization of normative paediatric blood pressure reference values. To date, there has been no nation-wide project in South Africa to determine nationally representative normal blood pressure reference values, nor to estimate the true prevalence of hypertension in the paediatric population of the country. This study will provide critical information on the understanding of blood pressure and hypertension in children, especially of African ancestry. Not only will this effort contribute to the development of the first nationally representative normal reference values of blood pressure but will also benefit healthcare providers in the sector with a clear guideline on the management of high blood pressure in children as developed by experts working with these challenges daily.
