Purpose Back pain affects people of all ages This may be associated with physical inactivity, and in the case of physical activity in different domains, the relationship with back pain is not clear in the literature The aim of this study was to estimate the prevalence of low back and neck pain and investigate their association in different domains of physical inactivity Methods 1011 randomly selected students participated in this study Neck and back pain were assessed using the Nordic questionnaire, whereas the Baecke Physical Activity questionnaire was used to measure physical activity domains Separate Binary Logistic Regression models were performed to investigate the association of physical activity domains with neck or back pain Results 174% of the students reported cervical pain, while 180% reported low back pain Older adolescents had a higher prevalence of cervical pain (244%) than younger adolescents (119%) (p value Conclusions The prevalence of neck and low back pain was higher in older adolescents and physical inactivity in the sporting context and occupational activities could be a risk factor to increase the chances of back pain

Back and neck pain prevalence and their association with physical inactivity domains in adolescents

To evaluate the use of digital devices, reading habits and the prevalence of eyestrain among urban Indian school children, aged 11–17 years. The study included 576 adolescents attending urban schools who were surveyed regarding their electronic device usage. Additional information on the factors that may have an effect on ocular symptoms was collected. Twenty percent of students aged 11 in the study population use digital devices on a daily basis, in comparison with 50% of students aged 17. In addition to using these devices as homework aids, one third of study participants reported using digital devices for reading instead of conventional textbooks. The majority of students preferred sitting on a chair while reading (77%; 445 students), with only 21% (123 students) preferring to lie on the bed and 8 students alternating between chair and bed. There was a significant association between the students who preferred to lie down and those who experienced eyestrain, as reported by a little over one fourth of the student population (27%). Out of 576 students, 18% (103) experienced eyestrain at the end of the day after working on digital devices. The increased use of digital devices by adolescents brings a new challenge of digital eyestrain at an early age. Our study reports the patterns of electronic device usage by school children, evaluates factors associated with eyestrain and highlights the need for further investigation of these issues.

Visual implications of digital device usage in school children: a cross-sectional study

Objective: The aims of this study were to assess the prevalence of temporomandibular disorders (TMD) among adolescents and to contrast the prevalence of TMD according to the DC/TMD clinical examination protocol versus the prevalence of pain related to TMD according to two screening questions.Material and methods: Two hundred and ten adolescents living in the county of Bergen, Norway, were offered an additional examination for TMD in connection with their regular dental check-up appointment. Five dental clinics were selected with differing socio-economic patient populations, as reflected by stratification of average levels of DMFT, and an equal number of girls and boys were invited to participate. The participants answered two screening questions for pain related to TMD followed by a clinical examination according to the DC/TMD protocol by five calibrated examiners.Results: Acceptable calibration results were obtained. Approximately 80% of eligible participants consented to partake. According to th...

Prevalence among adolescents in Bergen, Western Norway, of temporomandibular disorders according to the DC/TMD criteria and examination protocol

Background In the past decade, mobile phone usage rates have increased and there have been concerns that overuse of mobile phones may contribute to various musculoskeletal (MSK) problems. Objectives The aim of the present study was to systematically review available literature on the prevalence of MSK complaints, symptoms, and pathologies associated with mobile phone use. Study design Systematic review. Method In this systematic review, Medline (Pubmed), Wiley, WOS, and EMBASE electronic databases were searched for studies published in English between January 1, 2000 and March 25, 2019 using the following. Key terms ‘mobile phone’, ‘smartphone’, ‘musculoskeletal pain’, ‘pain’, ‘musculoskeletal symptoms’, and ‘musculoskeletal pathology’. Results The search strategy identified 196 papers, of which 18 met the inclusion criteria. Among the studies included in the systematic review, five were high quality, twelve were of acceptable quality, and one was of low quality. The review demonstrated that the prevalence of MSK complaints among mobile phone users ranged 8.2%–89.9%, and that neck and upper back complaints had the highest prevalence rates ranging from 55.8% to 89.9%. The most common MSK symptom associated with mobile phone use was pain. Myofascial pain syndrome, fibromyalgia, thoracic outlet syndrome, tendonitis, and De Quervain's syndrome were the most commonly associated MSK pathologies. Conclusion The evidence concerning MSK complaints among mobile phone is somewhat limited because the data were obtained from cross-sectional and case-control study results. Consequently, there is need for higher quality and prospective studies to better understand the relationship between mobile phone use and MSK symptoms and pathologies.

A systematic review of musculoskeletal complaints, symptoms, and pathologies related to mobile phone usage.

The COVID-19 outbreak forced Italian students to reduce their daily activities, inducing a seden-tary attitude that was worsened by distanced learning. This study aimed to survey the physical activity levels that were maintained before and during the social restrictions following the pan-demic, their correlation to musculoskeletal pain, as well as analyzing the impact of these COVID-19 restrictions on pain and fatigue that affects daily life activities. A total of 2044 students completed the online questionnaire, of which the results of 1654 participants were eligible. Before the pandemic, the levels of physical activity were distributed as: 19.9% no activity, 30.1% light ac-tivity, 21.5% moderate activity, and 28.5% high activity. After one year of the pandemic, 30.6% of the participants were inactive, 48.1%, 10.9%, and 10.5% stated as maintaining, respectively, light, moderate and high levels of physical activity. Furthermore, 43.5% reported neck pain and 33.5% stated to experience low back pain. Physical activity levels lower than 150 min/week may have predisposed students to suffer from neck pain (1.95 OR at 95% CI, 1.44-2.64) and low back pain (1.79 OR at 95% CI, 1.29-2.49). A positive correlation between physical activity levels, Verbal Descriptive Scale (VDS), and pain frequency have been observed for neck and low back pain (p-value < 0.05). Finally, low physical activity levels were associated with musculoskeletal pain onset and pain worsening.

One Year of COVID-19 Pandemic in Italy: Effect of Sedentary Behavior on Physical Activity Levels and Musculoskeletal Pain among University Students.

Objective: This study investigated the presence of musculoskeletal symptoms in high school adolescents from public schools and its association with electronic device use. Methods: The sample consisted of 961 boys and girls aged 14 to 19 years who answered a questionnaire regarding the use of computers and electronic games, and questions about pain symptoms and physical activity. Furthermore, anthropometric assessments of all volunteers were performed. The chi-squared test and a multiple logistic regression model were used for the inferential analysis. Results: The presence of musculoskeletal pain symptoms was reported by 65.1% of the adolescents, being more prevalent in the thoracolumbar spine (46.9%), followed by pain in the upper limbs, representing 20% of complaints. The mean time of use for computers and electronic games was 1,720 and 583 minutes per week, respectively. The excessive use of electronic devices was demonstrated to be a risk factor for cervical and lumbar pain. Female gender was associated with the presence of pain in different body parts. Presence of a paid job was associated with cervical pain. Conclusion: A high prevalence of musculoskeletal pain in adolescents, as well as an increased amount of time using digital devices was observed. However, it was only possible to observe an association between the increased use of these devices and the presence of cervical and low back pain.
