Young adults are paying the price for spending hours in front of the television, according to research which found that a third of 16 to 24-year-olds suffer back pain.
Research company Mintel found that young adults and pensioners are suffering from similar amounts of pain.
The study found that 34pc of 16 to 24-year-olds suffer from back ache compared with 38pc of over-65s.
Michelle Strutton from Mintel said: "The high incidence of back pain in youngsters is pretty alarming.
"Too much time sitting, weakens muscle tone and this can lead to back pain, which is becoming one of society's main issues and accounts for a high proportion of reasons for taking sick leave."
The research identified the top five ailments which are colds and flu, headaches, sore throats, coughs and back pain.
The study also found that women are more likely than men to complain of headaches, with 62pc of women saying they suffer from headaches compared with 49pc of men.
