Kyphosis occurs in Children, Adolescents and Adults.
Adolescent girls: Those with poor posture, who are at greater risk for postural kyphosis.
Boys: Those between the ages of 10 and 15, who are at greater risk for Scheuermann's kyphosis, a developmental disorder caused by excessive kyphosis, more common in boys than girls.
Older adults: Those with osteoporosis, who are at greater risk for spinal fractures that could lead to kyphosis.
People who have certain ailments, which affect the connective tissue, such as Marfan syndrome, are also susceptible.
