Investigators at the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health (NIH), have found that more than 1 in 20 US children have dizziness and balance problems.
Nearly 3.3 million (more than 1 in 20) children between the ages of 3 and 17 have a dizziness or balance problem, according to an NIDCD analysis of the first large-scale, nationally representative survey of these problems in US children. Prevalence increases with age, with 7.5% of children aged 15-17, and 6% of children aged 12-14 having any dizziness or balance problem, compared with 3.6% of children aged 6-8, and 4.1% of children aged 3-5. The research was led by investigators at the NIDCD, NIH.
The researchers report they found that girls have a higher prevalence of dizziness and balance problems (5.7%) compared to boys (5%). In addition, non-Hispanic white children have an increased prevalence of dizziness and balance problems (6.1%) compared with Hispanic (4.6%) and non-Hispanic black (4.3%) children. The findings were published in an online article in the January 27, 2016 edition of The Journal of Pediatrics.
According to the NIDCD, previous estimates of dizziness and balance problems in children have ranged from 5% – 18% and have been based on limited, foreign, population-based studies. To better understand the prevalence of these problems among US children, a team led by researchers from the epidemiology and statistics program at the NIDCD reportedly analyzed data from the Child Balance Supplement to the 2012 National Health Interview Survey (NHIS).
The NHIS is an annual survey conducted by the National Center for Health Statistics (NCHS) at the Centers for Disease Control and Prevention. The survey uses personal household interviews to gather information about a range of health topics. The Child Balance Supplement was included in 2012 and was the first large-scale supplement added to the NHIS survey to assess dizziness and balance problems among children.
NIDCD reports that the researchers analyzed data on nearly 11,000 children, aged 3 to 17, based on parents’ responses to the survey. Parents were asked if, in the past year, their children had been bothered by symptoms of dizziness or balance problems such as vertigo, poor balance/unsteadiness when standing up, clumsiness/poor coordination, frequent falls, fainting or light-headedness, or other dizziness and balance symptoms.
The researchers report that among children with dizziness and balance problems, 46% of parents reported that the children had poor coordination; 35.1% reported light-headedness; 30.9% had poor balance; 29% had vertigo; 25% reported frequent falls; and 8.5% had other dizziness and balance problems. Parents reported moderate or serious difficulties in 18.6% of children with dizziness and balance problems.
Overall, 36% of children with dizziness and balance problems were seen by a health professional and 29.9% received treatment. Of those whose parents reported moderate or serious difficulties with dizziness and balance problems, 71.6% were seen by a health professional, and 62.4% were treated.
The researchers also found that only one-third, or 32.8%, of parents with a child with a dizziness or balance problem reported having received a diagnosis of an underlying condition. The percentage of children diagnosed rose to 59.6% among children whose parents reported they had moderate to serious difficulties with dizziness and balance problems. Reported causes included neurological problems; ear infections; head or neck injuries or concussions; developmental motor coordination disorder; genetic causes; metabolic problems such as hypoglycemia; prescription medication or drugs; severe headaches or migraines; malformation of the ear; and vision problems.
