The prevalence of hypertension (HTN) in children is increasing. Early detection of HTN in childhood may prevent the occurrence of complications in adult age. Blood pressure (BP) varies between populations according to ethnic and environmental factors.

Setting And Design: Community-based multistage random sample of representative cohort from each region.
There are limited data on the pattern and prevalence of pediatric chronic neurologic conditions in the region. Therefore, the objective of this study was to establish the prevalence of these disorders in the Kingdom of Saudi Arabia. A multistage probability sampling design was used to select a random sample of Saudi households representative of the Saudi population.
View Article and Find Full Text PDFBackground And Objective: There is no published information on the prevalence of malnutrition in Saudi Arabia. The objective of this study was to establish the prevalence data.
Methods: The prevalence of nutritional indicators in the form of underweight, stunting, and wasting in a national sample of children younger than 5 years of age was calculated using the new WHO standards as reference.
Objective: To evaluate the regional difference in the prevalence of malnutrition in Saudi children.
Methods: Data for this study were collected over 2 years (2004 and 2005). A cross-sectional representative sample of the Saudi population of healthy children below 5 years of age was used to calculate the prevalence of malnutrition.
Objective: To explore the effect of the educational level of the head of household on the prevalence of malnutrition in Saudi children.
Methods: The study was conducted over 2 years in 2004 and 2005 in all regions of the Kingdom of Saudi Arabia (KSA). The design consisted of a stratified multistage probability random sampling of the population of the KSA.
Background: Although variations in growth between boys and girls have been reported, detailed descriptions according to age and growth parameters are not available.
Objective: The goal of this study was to determine the pattern and magnitude of differences in growth between boys and girls according to age that justify separate growth charts.
Methods: The data set was based on a cross-sectional representative sample of the Saudi population of healthy children and adolescents from birth to 19 years of age.
Objective: To evaluate the resting heart rate to define reference values for healthy Saudi children and adolescents.
Methods: To establish representative heart rate (HR) reference values for Saudi Arabian children and adolescents, a sample of children, and adolescents was selected by multi-stage probability sampling of the Saudi population from birth to 20 years of age. The selected sample represents Saudi children from the whole country.
Background/aim: To examine the liver size in Saudi children and adolescents.
Methods: A large sample of children was selected from the general population by multistage random probability sampling for the assessment of physical growth. A random subsample of children-newborns to 18 years old-was taken from this larger sample for this study.
Background And Objectives: Blood pressure levels may vary in children because of genetic, ethnic and socioeconomic factors. To date, there have been no large national studies in Saudi Arabia on blood pressure in children.Therefore, we sought to establish representative blood pressure reference centiles for Saudi Arabian children and adolescents.

Subjects And Methods: A nationwide nutritional survey of a sample of Saudi households was selected by the multistage probability sampling procedure.
Objective: To determine the prevalence and regional distribution of sickle cell disease in Saudi children.
Methods: A sample size of 45,682 children and adolescents from newborn to 19 years of age was selected by multistage random probability sampling of the Saudi households from each of the 13 regions of the country. The study is cross-sectional, community based, and conducted over 2 years from 2004 to 2005.
Background And Objectives: The 2000 CDC growth charts for the United States, a revision of the National Center for Health Statistics/World Health Organization (NCHS/WHO) growth charts, were released in 2002 to replace the NCHS/WHO charts. We evaluated the differences between the CDC growth charts and the Saudi 2005 reference to determine the implications of using the 2000 CDC growth charts in Saudi children and adolescents.
Subjects And Methods: The Saudi reference was based on a cross-sectional representative sample of the Saudi population of healthy children and adolescents from birth to 19 years of age.
Objective: To evaluate the trend in the nutritional status of Saudi children over a 10-year period.
Methods: The growth data collected between 1993--1994 were compared with those collected between 2004--2005 from all regions of the Kingdom. Both nutritional surveys had a similar design leading to representative samples of Saudi children determined by multistage probability sampling.
Background And Objectives: There is a high rate of consanguinity in Saudi Arabia; however, information on its relationship with genetic disorders is limited. The objective of this cross-sectional study was to explore the role of consanguinity in genetic disorders.
Subjects And Methods: The study sample was determined by a multistage probability random sampling procedure.
There is a high prevalence of consanguinity and bronchial asthma in Saudi Arabia. The objective of this study is to explore the effect of parental consanguinity on the occurrence of bronchial asthma in children. The study sample was determined by multistage random probability sampling of Saudi households.
View Article and Find Full Text PDFObjective: To report on the prevalence of consanguinity in each region of the Kingdom of Saudi Arabia including the variation in prevalence between urban and rural settlements.
Methods: The study was conducted over 2 years (2004-2005). A cross-sectional sample determined by multistage random probability sampling of Saudi households from each of the 13 regions of the Kingdom.
Objective: To establish reference growth charts for Saudi children and adolescents.
Methods: Multi-stage probability sampling of a cross-section of Saudi children and adolescents residing in all 13 regions of the Kingdom. Family interviews, and physical examinations of children and adolescents from birth to 19 years of age were conducted over a 2-year period (2004-2005).
