Introduction. Any delay in communicating needs verbally
relatively to what is considered normal for a specified age is
defined as speech delay and mawy be associated with a variety
of pathological conditions. A delay in speech development
may be a symptom of many disorders, including mental
retardation, hearing loss, an expressive language disorder,
autism, psychosocial deprivation, or an organic CNS defect.
Speech delay is a common childhood problem that affects 3 to
10 percent of children. The disorder is three to four times more
frequent in boys than in girls.
Aim. The aim of this study is to investigate the prevalence of
hearing impairment resulting in speech delay among children.
Material and methods. Forty-one speech-delayed children
aged 2 to 5, including 32 boys and 9 girls, diagnosed with speech
delay in 2011-2012 were audiologically.
Results. Hearing loss that could be a likely cause of speech
delay was diagnosed in 14 (34%) of the children. Risk factors of
the hearing impairment included low birth weight and perinatal
hypoxia. In children with normal hearing, speech delay was
attributable to neurological disorders, autism and Prader-Willy
Conclusions. The causes of delayed speech in the studied group
of children varied widely. In ca. 1/3 of the children, the delay
was due to hearing loss.
