Method This cross-sectional study was conducted from September to October 2022 at the University of Balochistan Quetta to find out the prevalence of neck pain and it risk factors. Data were collected randomly by distributing 500 questionnaires among the students irrespective of age, gender, department, and year of study. Data were analyzed using SPSS Version 23. Continuous variables were presented as mean ± SD, and categorical variables as frequencies and percentages. Univariate and multivariate binary logistic regression analysis were used to find out the risk factors associated with neck pain and a p-value <0.05 was considered significant.
Results The results revealed that the prevalence of neck pain was 73%. In MVBLR analysis, male gender (OR=0.360, p-value=0.000), students in 4th year (OR=3.281, p-value=0.002), Left handed (OR=0.395, p-value=0.002), the habit of physical exercise (OR=0.594, p-value=0.032), number of social media used in a day (OR=2.414, p-value=0.039), use of other electronic devices (OR=1.858, p-value=0.010), style of holding (OR=3.289, p-value=0.008) and posture adopted during smartphones use (OR=0.614, p-value=0.050) had a significant association with the neck pain during smartphone use among university students.
Conclusion In the current study high number of study, participants reported neck pain. Female gender, students in 4th year, left-handed, the habit of physical exercise, use of five or more social media applications, use of other electronic devices, and posture adopted on laying back were the risk factors associated with neck pain.
Key words neck pain, shoulder pain, smartphones, text syndrome
Smartphone technology has rapidly spread worldwide, with over 5 billion individuals having mobile devices, primarily smartphones for communication and entertainment [5]. Today's young adults have grown up with smartphones as integral parts of their lives. There is an observed increase in ownership and use of electronic devices among young adults, as these devices have gained significance due to their diverse capabilities [5-7]. A study reported that in the United States, 92% and in Australia, 95% of people aged 18 to 34 owned smartphones. However, as of January 2022, 82.90 million (36.5%) of Pakistan's total population were connected to the internet. This number of internet users in Pakistan increased by 22 million (35.9%) between 2021 and 2022 [8].
Globally, young adults aged 18-34 more regularly use smartphones and the internet than those aged 35 and above. There is also evidence that younger individuals are more likely to access the internet daily and engage in social networking. This regular use of smartphones can cause musculoskeletal disorders. Previous studies have reported a high prevalence range (20-82%) of shoulder and neck pain among college and university students related to smartphone and electronic device usage [9-15]. Few studies have reported the prevalence and risk factors associated with neck pain among smartphone users in Pakistan. This study will evaluate the prevalence of neck pain among smartphone users and the associated risk factors among students at the University of Balochistan, Quetta, Pakistan.
This cross-sectional study was conducted from September to October 2022 at the University of Balochistan (UOB) Quetta, Balochistan, Pakistan. The University of Balochistan is the province's first and oldest university, providing graduate and postgraduate courses in biological, health, social, computer and management sciences.
Study population
The undergraduate students who were enrolled and studying in different departments at UOB Quetta and were using smartphones were approach and randomly selected after inclusion and exclusion criteria. The UOB has different campuses, but the data was collected at the main campus situated on Seryab road Quetta. The number of students enrolled in different departments at the campus are 11000+, and the sample was selected using simple random sampling.
Inclusion and exclusion criteria
All the students who were regular and had been using the smartphone for the last one year and above were included, and those students who had a previous or recent history of musculoskeletal disorder, head or neck surgery, or any disc problem were excluded from the study.
Data collection
A questionnaire was designed by adapting a standardized Nordic questionnaire used for analyzing neck pain. The questionnaire was divided into three sections. The first section comprised socio-demographic questions, while the next section examined behavioral characteristics such as smoking and physical exercise routines. The final section addressed smartphone use and postural characteristics, including the purpose of smartphone use, total daily usage time, frequency of social media use, breaks while using the smartphone, frequently adopted postures while using the smartphone, smartphone position during use, style of holding the smartphone, and incidence of neck pain.
Before data collection, five students were briefed on the study's methodology, purpose, and ethical considerations. Written informed consent was obtained from all participants after briefly explaining the study's objectives, purpose, benefits, and risks. Suitable precautions were taken to protect the privacy of information during and after data collection.
Data Analysis
The data were analyzed using the Statistical Package for the Social Sciences (SPSS) Version 23. Continuous variables were presented as mean ± standard deviations (SD), while categorical variables were expressed as frequencies and percentages. Univariate analysis was performed to identify associations between independent variables and neck pain. All independent variables included in the univariate analysis were selected based on the literature review and their reasonable association with neck pain. Independent variables with a univariate analysis p-value of less than 0.2 were included in a multivariate binary logistic regression (MVBLR) analysis to obtain the final model of variables with a statistically significant association (p-value <0.05) with neck pain.
In order to find pertinent research, we conducted an extensive literature search using electronic databases (PubMed, Embase, Google Scholar, and Cochrane Library). Relevant keywords including "TAU protein antibodies," "Alzheimer's disease," "therapeutics," and "clinical trials" were used in the search strategy. Only English-language articles published between the start of the search and the present were included. Figure 1 is the flowchart outlines for the reviews.
Inclusion and Exclusion Criteria
The respondents filled out a total of 543 questionnaires out of which 43 incomplete questionnaire were excluded as shown in Figure 1. The socio-demographic characteristics of study respondents are given in Table 1. The mean age of the study respondents was 21.98+1.72, the majority of them were females 342 (68.4%), and 328 (65.6%) belonged to the age group 18-22 years, 462 (92.4%) of the respondents were unmarried, 362 (72.4%) from urban areas, 124 (24.8%) were enrolled in 2nd year and 120 (24.0) in the 4th academic year, while 422 (84.4%) were right-handed, 452 (90.4%) were non-smokers, and 290 (58.0) were having the habit of exercise.
Smartphone usage and posture characteristics of the study participants
The study respondents' smartphone usage and posture characteristics are discussed in Table 2. The majority of the study participants, 370 (74.0%) and 462 (92.4%) use smartphones daily for reading, texting, chatting, or other purposes on social media, respectively. 316 (63.2%) of the study participants do not use a smartphone daily for playing games, 130 (26.0%) participants use at least three social media apps on a typical day, and 432 (86.4%) use a smartphone daily for watching. For most participants, 304 (60.8%) spend 1-6 hours in a day on smartphones for texting and chatting, gaming, watching videos, reading, and other activities. 436 (87.2%) of the participants take a break while using the smartphone for different activities, and 298 (59.6%) participants use other devices like tablets, laptops, or desktops or others for playing games, chatting, reading, watching videos, browsing the internet or other activities along with smartphones. However, most of the participants, 348 (69.6%), do not use a desktop, 288 (57.6%) hold their smartphone below eye level, 250 (50.0%) participants use both hands while using their smartphone, 240 (48.0%) participants adopt sitting posture while using a smartphone.
Prevalence of neck pain in smartphones users
Three-hundred-sixty-four students (73%) experienced neck pain within the last 12 months, has been shown in Figure 2. Female students reported a higher incidence of neck pain (78.4%) than male students (60.8%). The prevalence of neck pain was higher among those aged 23-26 years (75.0%) and those aged 18-22 (72.0%). The prevalence of neck pain was higher among the students of 4th (81.7%), 5th (73.0%) and 3rd (73.2%) year, unmarried students (73.2%), students from rural regions (75.4%), non-smokers (66.7%), right-handed (74.9%) and students who were not having physical exercises (80.0%) as compared those who were having the habit of physical exercises (67.6%) as shown in Table 1.
Risk factors associated with neck pain in smartphones users
Different socio-demographic variables such as gender, age, marital status, residence, year of study, handedness, smoking, physical exercise and different variables related to smartphone use such as used smartphone for reading, used smartphone for watching video, used smartphone for gaming, used other electronic devices, number of social media used daily and total time per day on smartphone. The posture such as the position of the phone while using, style of holding smartphone, frequent posture adopted and taking break during smartphone use. All the above-mentioned variables were evaluated through univariates analysis, among them gender, year of study, handedness, the habit of physical exercise, used smartphones for reading, number of social media used in a day, hours spent in a day on smartphones, use of other electronic devices, hold, style of holding and posture adopted while using smartphone had a p-value <0.2 and entered to multivariate binary logistic regression (MVBLR) analysis as shown in Table 3. In the final MVBLR analysis, male gender (OR=0.360, p-value=0.000), students of 4th year (OR=3.281, p-value=0.002), Left handed (OR=0.395, p-value=0.002), the habit of physical exercise (OR=0.594, p-value=0.032), number of social media used in a day (OR=2.414, p-value=0.039), use of other electronic devices (OR=1.858, p-value=0.010), style of holding (OR=3.289, p-value=0.008) and posture adopted during smartphones use (OR=0.614, p-value=0.050) had a significant association with the neck pain during smartphone use among university students as shown in Table 4. This model fit was based on a non-significant Hosmer Lemeshow test (p-value=0.136) and an overall percentage of 72.8% from the classification table.

In the current study, the students of 4th year were (OR=3.281, p-value=0.002) more likely to experience neck pain than the first-year students. Similar findings were reported in other studies conducted in Ethopia and China [20, 28]. These students had online classes during the period of COVID-19 which led them to long-term use of electronic devices, long practice hours, use of different social media platforms, and regular use of smartphones for longer period of timesm this suggests that neck pain may develop throughout the study. The current study also found that students who did not exercise regularly were more likely to get neck pain (p-value=0.032) than those who did exercise regularly. Similar findings were reported by other studies conducted in Ethiopia and China [20, 29]. This could be because muscles that aren't as strong or flexible can cause the structures of the neck to be out of place, which can lead to neck pain. While the students who exercised regularly were able to strengthen, lengthen, improve their flexibility, and make their muscles and ligaments strong enough to support and keep their necks in the appropriate posture so they could function effectively and avoid injury [30].
The current study also found that students who used five or more social media applications every day were (OD=2.414, p-value=0.039) at graeater risk to develop neck pain. Simillar results have been reported by other studies conducted elsewhere [16, 31]. This could be because they spend more time on social media platforms and do it all the time. Those students who were using other electronic devices with smartphones were (OR=1.858, p-value=0.010) at greater risk to develop neck pain than those students who were only using smartphones. Similar findings were reported in a study conducted in Singapore, which found that people who used different communication devices besides smartphones are 1.61 times more likely to get neck pain [21]. This means that when students use more devices daily, they also spend more time using them each day, which could make them more likely to get neck pain. Those students who were using the left hand to hold and those who were laying on their back position were more likely to develop neck pain with p-value=0.008 and p-value=0.050 respectively. This could be because their steady hand may not be left hand, and its muscles are not as flexible or strong which can cause misalignment of the neck's structures and causes neck and shoulder pain.
The study was limited because it was a cross-sectional convenience sampling study that only looked at university students. This research could not assess the intensity, duration, and nature of neck pain among the study participants. In addition, no suitable posture assessment technique was used.
We extend our gratitude to all the students who participated in this research.
