Abstract
ABSTRACT: Study Design. A cross-sectional survey of 2083 schoolchildren.Objectives. To investigate the prevalence of non-specific low back pain (LBP) among schoolchildren between 10 and 18 years old in China.Summary and Background Data. LBP have been a serious health problem in schoolchildren. Based on the literature, the lifetime occurrence of non-specific LBP in children and adolescents varies between 7% and 72%, but little is known about LBP among this demographic group in China.Methods. Schoolchildren aged 10-18 were sampled from two grades in an elementary school and four grades in a secondary school. Participants were asked to fill in a questionnaire on LBP. The questionnaire addressed demographic items, anthropometric factors and characteristics of non-specific LBP, such as frequency, duration, nature, pain scale. Non-specific LBP is defined as the pain in the back from the 12th ribs to the buttock area without organic factors. A total of 2235 questionnaires were distributed, of which 2100 were answered, a response rate of 93.7%. Among those answers, 2083 (977 from male students and 1106 from females) provided measurable data.Results. The occurrence of non-specific LBP was high, with 29.1% students suffering from this condition in the past three months (24.7% in males, 33.1% in females). In addition, an increased occurrence was observed with age. The occurrences of LBP in 10-14 years old and 15-18 years old were 21.5% and 38.2%, respectively. In several aspects of LBP, statistically significant differences were observed between males and females, including the frequency of the pain (P = 0.003), the nature of the pain (P = 0.000), the likelihood of seeking for medical assistance (P = 0.007), the impact on normal daily life (P = 0.016), and the occurrence of LBP after bending over the desk for a period of time (P = 0.024). Female students had more frequent LBP and were less willing to see a doctor. In addition, more female students (45/366) had LBP accompanied with radiating pain than male students (20/241).Conclusions. There is a high prevalence of LBP in Chinese schoolchildren. The occurrence of LBP increases with age in both genders. LBP is significantly more prevalent in females.
