Introduction
The widespread adoption of smartphones has revolutionized communication and access to information globally.In Saudi Arabia, as in many countries, smartphone penetration is exceptionally high, with a significant proportion of the population relying extensively on these devices for daily tasks, communication, and entertainment [1].While smartphones offer undeniable convenience, prolonged usage has raised concerns regarding their potential health impacts, particularly on musculoskeletal health [2].
Studies globally have increasingly reported a range of musculoskeletal symptoms associated with smartphone use, often referred to collectively as smartphone-related musculoskeletal disorders [3].These symptoms commonly include neck pain, headaches, shoulder pain, and hand numbness, attributed to poor posture during smartphone use, repetitive movements, and prolonged periods of device interaction.Such issues are exacerbated by the inclination to tilt the head forward and downward while using smartphones, placing increased strain on the cervical spine and upper extremities [4].
In Saudi Arabia, a country where smartphone usage is integrated deeply into daily life across all age groups, understanding the prevalence and impact of smartphone-related musculoskeletal disorders is crucial for informing public health strategies [5].Despite the growing recognition of these issues internationally, there remains a paucity of research specifically addressing smartphone-related musculoskeletal disorders among Saudi Arabian adults [6], particularly in regions such as Riyadh.
This study aims to fill this gap by investigating the prevalence of musculoskeletal symptoms associated with smartphone use among adults in Riyadh, Saudi Arabia.By identifying the extent and nature of these symptoms, this study aims to provide insights into the public health implications and inform targeted interventions to promote ergonomic practices and mitigate health risks associated with smartphone use in the region.

Study design and participants
This was a cross-sectional study conducted in Riyadh, Saudi Arabia, to assess the impact of smartphone use on musculoskeletal health.The study was approved by the Jazan University Research Ethics Committee.The study population comprised individuals aged 18 years and older who were smartphone users.Participants were recruited using a convenience sampling method from various locations, including universities, workplaces, and public areas.

Data collection
Data were collected using a structured questionnaire (See Appendices), distributed both online and in paper form.The questionnaire gathered information on demographic characteristics, smartphone usage patterns, awareness of the effects of smartphone use, and the prevalence and severity of musculoskeletal symptoms.
The questionnaire was pre-tested in a small group to ensure clarity and relevance.

Variables and measurements
Primary variables included demographic information (gender, age, marital status, education level, and nationality), smartphone use (daily usage duration and typical neck position while using a smartphone), awareness of the effects of smartphone use on health, and the prevalence and severity of symptoms (neck pain, arm pain, shoulder pain, upper back pain, headaches, stiff neck, and hand numbness).Symptoms were measured using a Likert scale ranging from "strongly disagree" to "strongly agree".Additional variables related to "text neck" syndrome included awareness, sources of information, diagnosis, and associated symptoms and severity.

Data analysis
Data analysis was done with IBM SPSS Statistics for Windows, Version 27.0 (Released 2020; IBM Corp., Armonk, New York, United States).Descriptive statistics were used to summarize demographic characteristics, smartphone use patterns, and prevalence of symptoms.Frequencies and percentages were calculated for categorical variables, while means and standard deviations were used for continuous variables.

Discussion
This study highlights the significant prevalence of musculoskeletal symptoms among smartphone users in Riyadh, Saudi Arabia.The findings indicate a high incidence of neck pain, with 81.1% of participants reporting experiencing this symptom.Other common complaints included headaches (63.0%), hand numbness (32.9%), and shoulder pain (49.4%).These results align with existing literature that associates prolonged smartphone use with musculoskeletal discomfort and pain [7][8][9].
Our findings are consistent with previous studies conducted in various regions, which have documented similar patterns of musculoskeletal symptoms linked to smartphone use.For instance, a study found a high prevalence of neck and shoulder pain among smartphone users, particularly those who used their devices for extended periods and maintained poor postures [10].Similarly, studies have reported increased incidences of text neck syndrome and associated musculoskeletal issues among heavy smartphone users [10,11].
The high prevalence of musculoskeletal symptoms observed underscores the need for public health interventions aimed at mitigating the adverse effects of smartphone use [12].Educational campaigns to raise awareness about proper smartphone ergonomics and posture could be beneficial [13].Additionally, incorporating regular breaks and exercises to alleviate tension and strain may help reduce the incidence of these symptoms [14,15].
Future studies should consider longitudinal designs to better understand the causal relationships between smartphone use and the development of musculoskeletal symptoms.It would also be valuable to explore the effectiveness of various interventions aimed at reducing these symptoms among smartphone users.
Expanding the research to include diverse populations and settings could provide a more comprehensive understanding of this public health issue.
This study has several strengths, including a comprehensive assessment of a wide range of musculoskeletal symptoms and the use of a structured questionnaire to ensure systematic data collection.The sample size was adequate, providing a robust dataset for analysis.However, some limitations should be acknowledged.The use of convenience sampling may limit the generalizability of the findings to the broader population.Additionally, the cross-sectional design precludes the ability to establish causality between smartphone use and musculoskeletal symptoms.

Conclusions
This study underscores the widespread prevalence of musculoskeletal symptoms associated with smartphone use among adults.Neck pain emerged as the predominant issue, followed by headaches, shoulder pain, and hand numbness.These findings emphasize the urgent need for public health interventions aimed at promoting ergonomic practices and raising awareness about the potential health risks of prolonged smartphone use.Implementing strategies such as educational campaigns on proper posture and regular breaks could help mitigate these symptoms.Further research is warranted to explore longitudinal impacts and evaluate the effectiveness of interventions in reducing musculoskeletal discomfort among smartphone users.
