Abstract Background The one-month prevalence of back pain in children and adolescents has been reported at 33, 28 and 48% at ages 9, 13 and 15 respectively. There are many suspected risk factors and triggers of back pain in young people. Objective The purpose of this scoping review was to identify potential risk factors and potential triggers for back pain in young people. The purpose of part I was to identify potential risk factors for incident and episodic back pain in young people. Part II included all eligible studies with unclear or mixed types of back pain. Methods Due to the vast number of studies on “risk factors” for back pain, a two-part scoping review of the literature was chosen as the best way to summarise the evidence. We adhered to the PRISMA-ScR guideline for scoping reviews. General potential risk factors and triggers for back pain in children and young adults (≤ 24 years) were included, incorporating physical, environmental, and/or physiological factors. A search was conducted using PubMed and Cochrane databases from inception to September 2018, limited to the English language. Within part I, and because of their importance, only the results of the studies that investigated risk factors of incident back pain and back pain episodes are presented. Results The search identified 7356 articles, of which 91 articles were eligible for this scoping review. The majority of the eligible articles had an unclear definition of back pain (results presented in scoping review part II). There were 7 inception cohort studies included and 1 cohort study that met the criteria for part I. The most consistent risk factors for incident and episodic back pain are female sex and older age. Conclusion Due to inconsistent ways of reporting on the type of back pain, no definitive risk factor for back pain has been identified. In general, females often report more symptoms, also for other diseases, and older age is not a useful risk factor as it merely indicates that the onset may not be in childhood. Clearly, the time has come to study the causes of back pain from different angles.

Immunization with formaldehyde-inactivated vaccine is recommended for all children and young adults. The course recommended earlier was two 1-ml intramuscular injections (1 month apart) followed by a third 1-ml injection (after an interval of approximately 7 months). This is probably adequate for older children and adults. Preliminary evidence indicates that a considerable proportion of infants have a less than optimal or relatively short-lived antibody response when immunized in this fashion. Vaccination of infants should be started at about 1½ to 2 months of age. The Committee recommends that children under 5 years of age be given a series of three 1-mi injections (1 month apart) followed by a fourth injection (up to 8 months later) and then a fifth injection (at about 4 yearsof age). In the present state of knowledge, additional injections seem advisable as indicated in Table I. A recall injection should be given before traveling abroad or before entering an epidemic area. Preparations containing inactivated poliovirus vaccine combined with diphtheria and tetanus toxoids and pertussis bacilli are now available. Such quadruple preparations should be given according to the manufacturer's directions, in general adhering to the schedule presently used for DPT (see Table I). For reasons of safety and to avoid possible loss of antigenic potency, it is considered advisable for physicians not to improvise mixtures of combined diphtheria, pertussis, and tetanus antigens and poliomyelitis vaccine. See table in the PDF file There are few contraindications to poliomyelitis vaccination. It may be performed safely at any time of the year, even when poliomyelitis is prevalent.
