Objective to investigate whether the weight of the schoolbag is related to back pain and back pathology in school-age children. Design Cross-Segmentation Research
Schools are set up in northern Galicia, Spain.
All the patients were children aged 12-17.
The interventions included body mass index, age and gender.
The main results measured back pain and back pathology.
Results a total of 1403 children were analyzed. Of these, 61.
4% of people have more than 10% of their backpacks.
People carrying the heaviest backpack have a 50% higher risk of back pain (OR 1. 50 CI 95% 1. 06 to 2. 12)
The risk of back pathology increased by 42%, although the final result was not statistically significant (OR 1. 42 CI 95% 0. 86 to 2. 32).
Girls have a higher risk of back pain than boys.
Conclusion carrying a backpack increases the risk of back pain and may increase the risk of back pathology.
The prevalence of school children carrying heavy backpacks is extremely high.
Prevention and education activities should be carried out in this age group.

Back pain is currently a health problem for school children and it can limit daily lifeLife activities.
Sedentary lifestyles may be the most important factor in determining back pain in school-age children.
According to the national health survey of Spain 2006, 11.
Of the students aged 10-15, 8% thought they were sedentary.
Due to lack of physical activity, the muscle tension in the back is reduced.
Some studies have shown that people with back pain in adolescence are more likely to develop into low back pain after adulthood, or that heavy backpacks can cause muscle problems in the neck, shoulders and back, such as scoliosis
Experts suggest that children in schools cannot carry food weighing more than 10%.
The aim of this study was to analyze the effects of backpack weight on back pain and back pain.
Topic and method this is a cross
Sectional analysis of school-age children aged 12-17 in the 2005-2006 academic year in northern Spain.
11 schools in the region participated in the study.
What is already known on this theme school backpack is related to back pain and it is thought that they can create back pathology in adult life.
In different countries, the prevalence of back pain and backpack weight varies greatly among school-age children.
Few studies analyzed the relationship between backpack weight and back pathology in school-age children.
61. What has been added to this study. 4% and 18.
The backpack weight of 1% of participants exceeded 10% and 15%, respectively.
Those carrying the heaviest backpack had an increased risk of back pain by 50%, and the risk of back pathology was close to a significant level.
On a digital scale with a comprehensive height meter, school children gain twice their weight (Secca 764, Spain;
No coats and items for the first time constitute an extra weight (
Mobile phones, keys, coins, etc)
But they carried their backpacks that day, and there was no backpack for the second time.
Get the height, use high heels to put the child\'s back on the height meter.
The academic authority knows the weighted day, but the school children do not know, which is randomly selected.
Parents of school children or legal tutors filled out a questionnaire on the way children live, with special emphasis on the frequency of physical activity (at school)
And the duration of sedentary activities at home.
The presence of a lesion or pathology previously diagnosed by a doctor (
Such as scoliosis, camel back)
In addition, back pain over 15 days in the previous year was determined.
We compared the children initially included in the school with the features of the children in the final analysis.
Two logistic multivariate models were used, each as the primary dependent variable, the presence or absence of pain over 15 days in the previous year and the presence or absence of back pathology were used.
In these two models, the main independent variables are the weight of the bag classified by four digits.
Adjust the variable to gender and age (continuum)
Body mass index (quartiles)
Sports activities (yes/no).
The results were obtained by the Social Science statistical software package v17. 0 (SPSS).
The research programme was approved by the ethics committee of Burela hospital.
The results were initially included in 2135 school children and 1403 (65. 7%)were analysed.
There was no difference between school children analyzed and excluded.
The average age of participants was 14 and 92.
2% used a backpack with two straps.
The average weight of the bag is nearly 7 kg. In all, 61.
4% of the participants carried bags weighing more than 10% and 18.
Weight of 1% more than the 15%; 25.
Last year, 9% reported back pain for more than 15 days.
The most common pathology is scoliosis (
Reported pathology 70%)
The second is lower back pain and fracture (10% each).
The risk of back pain increased by 50% in participants carrying schoolbags for more than 15 days at a maximum of four (OR=1. 50 CI 95% 1. 06 to 2. 12)(table 1).
Girls are at a higher risk of back pain, and risk increases as they age.
When analyzing the relationship between bag weight and back pathology, there is a non-
An important association for those weights on a maximum of four points (OR=1. 42 CI 95% 0. 86 to 2. 32).
The risk of back pathology in girls was higher, and the risk of back pathology was observed to increase with age (table 2).

Most school children carry more backpacks than the recommended weight.
Many studies have found that backpacks significantly alter posture and gait, resulting in a change in head and neck angle, shoulder asymmetry, and even lumbar anterior protrusion.
In the long run, these changes in biochemistry can lead to chronic pain and the emergence of back disease.
20%-45% of young people aged 14-18 have back pain for more than 15 days.
A study conducted in northeast England in 2002 showed that the prevalence of lower back pain was 24%, and the prevalence of girls was higher than that of boys.
Another study conducted by Negrini and Negrini3 in Italy found that 11-year-
The backpack on the back of the old child is as heavy as 20% of their weight, and there are 58.
4% of people experience back pain more than once in their lives.
Girls are more likely to experience back pain and back pathology than boys, although there is no gender difference in backpack weight.
Grimmer et al observed that when carrying a backpack, girls were more prone to changes in the cranial neck angle, a association that became stronger with age. The cross-
The segmented design of this study is a limitation because it limits the causal inference of its discovery.
In this type of study, it is difficult to measure past events such as pain that lasted more than 15 days.
Other factors that have not been studied, such as poor physical fitness, poor back posture, structural scoliosis and high mobility, cannot be excluded as the real cause of back pain.
The fact that backpacks may often be carried with one strap instead of two, combined with the weight of the incidence of back pain.
The strength of this study is the sample size, which allows accurate estimation based on gender, age, body mass index, and physical activity.
The results obtained have a strong meaning.
Many children carry too many backpacks, which is not allowed for employed workers.
We strongly encourage the medical and educational sector to start advising parents and school children about the risks posed by heavy schoolbags and the fact that such risks are easily reduced.
