Abstract
Objectives: To estimate the prevalence of depression among Saudi adolescents and identify its correlates.
Methods: This was a cross-sectional study using a multistage random technique that included students at the intermediate and secondary levels in Riyadh, Saudi Arabia. Patient Health Questionnaire (PHQ-9) was used as a tool, in addition to a survey of the potential risk factors. Binary logistic regression was conducted.
Results: Out of 960 students, 32.4% were found to have moderate to severe depression. The age group of 16-19 years was more at risk. Female gender and low father’s education level were significant predictors of depression. Less internet use and more physical activity are considered a protective factor against depression, OR -0.531 (95% CI: 0.315-0.894) and OR -0.668 (95% CI: 0.468-0.953), respectively. Whereas the physical abuse, OR 2.047 (95% CI: 1.287-3.255) and emotional abuse, OR 2.576 (95% CI: 1.740-3.813) considered risk factors for depression.
Conclusion: The prevalence of depression among Saudi adolescents is worrisome. Urgent and firm actions should be taken in response to the increasing prevalence of depression worldwide.
Depression is a common mental disorder that can occur for different reasons. However, several factors increase the vulnerability to depression, such as genetics, familial environment, personal characteristics, and severe stress. Some researchers found an association between depression and several other factors, such as being female, family history of depression, low income, negative cognitive style, and negative life events.1,2 Depression can be diagnosed according to the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, fifth edition, (DSM-V) criteria. An individual must experience 5 or more symptoms during the same 2-week period, and the symptoms must not be a result of substance abuse or another medical condition. At least one of the symptoms should be either 1) depressed mood or 2) loss of interest or pleasure.3,4 Depending on the number and severity of symptoms, an episode of depression can be categorized as mild, moderate, or severe.2,5 Adolescents aged 10-24 years comprise nearly 25% (1.8 billion) of the world’s total population, which is 7.3 billion population.6 Of the 1.8 billion, almost 9 out of 10 live in less developed countries.6 In the Arab region, most of the population is below 25 years.7 Likewise, in Saudi Arabia (SA), 20% of the 28 million people are between 10 and 19 years.8 There has been an 18% increase in the prevalence of depression between 2005 and 2015.9 This reflects the global population’s overall growth and a proportionate increase in the age groups where depression is more prevalent. The total number of people living with depression worldwide is 322 million. The prevalence of depression in adolescents falls within the wide range from 14.2% to 42.9% reported by previous studies conducted in Saudi Arabia.10-13 The dilemma in adolescent depression is that it is not easy to detect because of its nonspecific symptoms and atypical presentation.14 Suicide, which is a major consequence in depressed adolescents, is the second leading cause of death between 15 and 29 years of age globally.1,9,15 It is documented to be the second leading cause of death in the 10- to 19-year-old age group in the United Kingdom.14 It was also reported as the second leading cause of death in the 15- to 19-year-old age group by the Centers for Disease Control and Prevention in its report of the Underlying Cause of Death 1999-2019 released in 2020.16 More than half of adolescent suicide victims were reported to have a depressive disorder at the time of death;17 hence, these reports reflect the risk of an untreated severe depressive episode, leading to suicidal death, especially in adolescents. Moreover, several studies have stated that depression in adolescents tends to continue throughout life.9,18
Although multiple studies in Saudi Arabia have confirmed an increase over the past few years in students suffering from depression.10-13 More studies, including a more representative sample, are essential to identify depression risk factors in adolescents. This study aimed to estimate the prevalence of depression among Saudi adolescents, its severity, and identify its correlates. The findings could pave the way for developing depression prevention and treatment services for at-risk students.
Methods
A quantitative observational cross-sectional study targeting students at the intermediate and secondary levels in Riyadh was conducted between January 2019 and April 2019.
Study participants were included based on the following criteria: Saudi male and female adolescent students aged between 12-19 years. Students with any previous diagnosis of the mental condition were excluded.
As the sample will be taken from intermediate and secondary schools, namely, adolescents from Grade 7 through Grade 12 were included, a cut-off of 12-19 years was used. This cut-off (12-19) was mentioned in the literature as a definition of adolescence by Erik Erikson19 and Colarusso.20 In the recent literature, this cut-off was used widely in the researches concerning adolescents,21-23 including Asian countries24 and depression-related researches.25-27 A study cohort comprising 929 adolescents was required based on the following equation: Given that z = 1.96, p=32%, d= ±3% n = [1.962 × 0.32 × (1 - 0.32)] / 0.032, n = 929 Where z is constant, p is the estimated prevalence of depression in previous studies, d is the margin of error, and n is the sample size.
A multistage random technique was applied to achieve the geographical distribution of the sample population. Riyadh was divided into 5 sectors (north, south, east, west, and center). As most adolescents are enrolled in schools, a list of schools from each sector was obtained from the general administration of public education in Riyadh; 4 schools were selected from each sector randomly. The schools were stratified into 6 levels, from the first-year intermediate to third-year secondary level; from each level, a class was selected using a simple random technique. Ten students from each class were asked to participate; every other student in a row was asked to participate to equal the number of students sitting in the front rows with the back rows.
Upon revising the literature, the tools used for depression screening are the Center for Epidemiological Studies-Depression Scale28), the Beck Depression Inventory-II,29 and the Patient Health Questionnaire (PHQ-9), which consists of 9 items that focus on the Diagnostic and Statistical Manual (DSM-IV) criteria.30 Among these, the PHQ-9 was found to be a useful instrument for identifying and initiating the diagnosis of depression. The PHQ-9 had the highest positive predictive value, with a sensitivity of 73% and specificity of 94%.31 A recently published study demonstrated that the Arabic version of the PHQ is a valid and reliable tool to screen for depression in a Saudi population.32
Data were collected by trained data collectors using a questionnaire composed of 3 parts: the first part was about sociodemographics such as age, gender, nationality, school grade, type of school, and parents’ education and marital status.
The second part was the PHQ-9, which consisted of 9 items used to screen depression. Each item was rated on a four-point scale ranging from 0 (not at all) to 3 (nearly every day) for a total score of 0 to 27.30 The total score obtained from the PHQ-9 was used to determine the presence and severity of depression and was categorized as 1-4, minimal; 5-9, mild; 10-14, moderate; 15-19, moderate to severe; and 20-27, severe depression.30 The specificity and sensitivity of the PHQ-9 were estimated based on multiple studies to be 89% and 81%, respectively.30,33 The cutoff score for positive screening for depression is 10 points.30
The third part focused on the potential risk factors for depression, including daily Internet use, hours of playing video games, relationship with family and friends, physical activity, physical abuse, and emotional abuse. A pilot study was conducted in Riyadh’s intermediate schools to assess the questionnaire’s clarity and comprehensiveness. It appeared to be well understood by the students.
Ethical approval was obtained from the IRB Committee of King Saud University, College of Medicine, Riyadh, Saudi Arabia. The investigators obtained consent from the school administration and participants prior to data collection. The questionnaire’s consent form included a clear explanation of the research, its objectives, and its impact. Participants’ anonymity was assured by assigning each participant with a code number for analysis only.
Statistical analysis
Data were analyzed using IBM SPSS Statistics for Windows, version 25.0 (IBM Corp., Armonk, N.Y., USA). Frequencies and percentages are reported for categorical variables. Chi-square was applied to observe associations between categorical variables. A p-value of <0.05 was considered statistically significant. Bivariate analyses were conducted to discern any nonlinear relationships or interaction effects and examine each independent variable’s associations and the dependent variable, namely, depressed or not depressed, as the cutoff score for positive screening for depression is 10.30 Binary logistic regression, including those statistically significant variables, was conducted independently estimating the relationships between those variables and the depression.
Results
Table 1 shows the participants’ sociodemographic data with correlation to the severity of depression. Of the 960 Saudi adolescents, 419 (51.7%) were 16-19 years old, and 464 (48.3%) were 12-15 years old. Four hundred ninety-three (51.4%) participants were male and 467 (48.6%) female. A total of 600 (62.5%) participants were from private schools. Students whose parents lived together were 870 (90.6%), those whose parents were divorced were 63 (6.6%), and those who were orphans were 27 (2.8%). Out of 960, 649 (67.6%) had mild depression, 194 (20.2%) had moderate depression, 117 (12.2%) had severe depression. Out of 960 participants, 817 (85.1%) used the Internet for 3 hours and more. Only 34 (3.5%) had a poor relationship with their family. Only 40 (4.2%) had a poor relationship with their friends. Most students (64.4%), not physically active. Seventeen percent of participants suffered from physical abuse. Approximately 26.9%, suffered from emotional abuse. There is a significant association between age and depression severity (p=0.002) as age increased. Compared to males, females had a significantly higher depression prevalence with a higher severity level (p=0.000). Public school students had a higher depression prevalence than private school students (p=0.004). A significant association was found between the father’s education level and the prevalence of depression (p=0.004). Whereas the mother’s education level was not found to be a significant factor (p=0.159). The parent marital status was appeared to be associated significantly with depression severity (p=0.031). There is a relationship between depression and relationship status with family or friends. Students with poor relationships with family or friends had the highest prevalence of depression; in contrast, students with very good relationships with family or friends had the lowest prevalence of depression (p=0.000). Although more internet usage is associated with depression severity (p=0.000), no significant association was observed between the severity of depression and playing video games (p=0.169). Students who physically active had a lower prevalence of depression (p=0.000). Students who were physically or emotionally abused had a higher prevalence of depression (p<0.000). The severity of depression appeared to have a relationship with the difficulty of performing tasks (p=0.000), as shown in Table 1. People with severe depression reported having more difficulties performing daily activities than those with lower levels of depression, indicating the disease’s burden.

Table 2 shows the binary logistic regression results of the possible predictors of depression. Although the age group of 12-15 seems to be less likely to have depression OR: -0.775 (CI 95%: 550-1.092), the association was not significant. Also, the type of school was not found to be a predictor. Gender is a significant predictor. Male students will be less likely to have depression, OR: -0.539 (CI 95%: 0.366-0.794) compared to female students. The father’s education level is a predictor of having depression, namely, if the father has a low educational level, the student will have 1.955 times (CI 95%: 1.271-3.006) more chance to have depression. A student who lived with both parents will be less likely to develop depression, OR: 0.576 (CI 95%: 0.236-1.409). Although the initial correlation was positive for parents’ status, it was not significant in the logistic regression. Less internet use appeared to have a protective effect from depression, OR: 0.531 (CI 95%: 0.315-0.894). A poor relationship with family is a strong predictor of depression with OR: 9.163 (CI 95%: 3.217-26.1). Also, poor relations with friends will be associated with depression, OR: 3.637 (CI 95%: 1.660-7.969). Staying physically active is considered a protective factor against depression, OR: 0.668 (CI 95%: 0.468-0.953). Whereas the physical abuse, OR: 2.047 (CI 95%: 1.287-3.255) and emotional abuse, OR: 2.576 (CI 95%: 1.74-3.81) considered risk factors for depression.

Discussion
A depression diagnosis is relatively common in children and adolescents and is strongly associated with morbidity and suicidal tendency;34 thus, it is important to have further information about it. A survey conducted in the United States targeting adolescents showed that the 1-year prevalence of major depression was 8%.15 This study’s outcome showed a prevalence of 32.4%, which lies within the range reported previously. A survey conducted in Abha and Aseer regions on adolescent schoolboys showed that 38.2% had depression.12 A study conducted among high school students in the Qassim region showed that 34% were mildly depressed, 24.6% were moderately depressed, and 15.4% were moderate to severely depressed.35
Several studies have shown an increase in the level of depression with increasing age into adolescence.36,37 In India, Jaisoorya et al,38 also reported increased depression with older adolescents. The Jeeluna national study found that feeling deeply sad or hopeless and worried was significantly more prevalent among females and older adolescents (p<0.0001),39 which is consistent with the findings of this study, where depression among female adolescents was more prevalent than those among males.
As the severity of depression was showed significant gender differences in the adolescent population. Lutz Wartberg et al37 study showed that girls are 2.36 times more likely to be depressed than boys. The Qassim region study also showed a significant relationship between depression and gender.35 Females tend to be the predominant gender in the prevalence of depression. A study in 2015 showed that 42.9% of secondary school girls in Taif city have significant depression,40 which was the highest prevalence of depression among the studies conducted in Saudi Arabia concerning this age group.
Saudi Arabia provides free education to its citizens through public schools, which may be a good choice for lower-income families. The school type can give us an indication of the financial well-being of the student’s family. This study found that students who went to public schools have a higher prevalence of depression, which could be due to the many challenges public school students face, such as poor health care, poor student counseling, inappropriate educational environment, and many other factors requiring further investigation.
Depression among adolescents is significantly affected by parents’ level of education. Students who had less educated fathers had a higher prevalence of depression than their counterparts; this could result from a lack of knowledge of the disease and inappropriate interventions, which might worsen their condition.
Jaisoorya et al38 reported that the student who is not living with both parents was significantly associated with psychological distress. The depression resulted from a lack of support at home and increased responsibilities of the adolescent or the emotional burden forced upon the student to not live like his peers. Two percent of the study population was orphaned; only 2 participants had severe depression according to the PHQ-9 scale. The culture in Saudi Arabia may have a role in such results as Saudis tend to have large families that can provide emotional and financial support to the less fortunate kids, and dedicated specialized governmental institutions offer care and aid to the people in need, which may have contributed to the lower prevalence of depression among orphaned adolescent students.
Poor relationships with family and friends negatively affect students’ lives. An increase in the level of depression is noted in those who have poor relationships with their friends and families, as shown by this study. A study conducted in Saudi Arabia achieved similar results with this study, where a strong association between depression and relationships with peers and family was established.11 The Jeeluna national survey found that poor relationships with parents, negative body image, and chronic illness were significantly associated with feeling sad or hopeless.39 Some researchers support the argument that Internet addiction can be associated with depression,41 which aligns with this study results. The results show that with increased daily use of the Internet, there is an increase in the prevalence of depression. In comparison, other researchers have stated that Internet abusers share common behavioral mechanisms with depression,42 namely, Internet abusers were associated with a depressive state but not a depressive trait. Thus, further studies are required to test the relationship between Internet addiction and depression.
The current study results showed that increased daily physical activity was inversely proportional to a higher prevalence of depression; physical activity, as stated by another study, has beneficial effects on depression symptoms comparable to antidepressant treatments.43
A high percentage of Saudi adolescent students reported suffering from domestic physical (17%)and emotional abuse (26.9%). Exposure to either of these 2 factors was significantly associated with a higher prevalence of depression, indicating that the depression could be attributed to these 2 factors more than other factors listed in this study.
Domestic abuse may have a direct role in depression. Simultaneously, its indirect contribution is the decrease in parents’ trust that may put the student in an isolated position with helplessness and lack of support or place them in a long-term state of self-doubt. This highlights the extreme importance of preventing these 3 factors: encouraging parental counseling after marriage, providing hotlines to ensure appropriate early intervention, or increasing the student’s counselor’s role in schools.
Approximately one-third of the adolescent student population was screened positive for depression, which shows the importance of addressing this issue. As recommended by the United States Preventive Services Task Force, annual screening should be carried out in schools31 and improve schools’ emotional and environmental states.
The study’s strength was that it was carried out with a valid tool to screen for depression using a multistage random technique to achieve the sample population’s geographical distribution. The study limitation was that the results could not be generalized to all Saudi adolescents. We need to conduct a national multicity study to obtain a precise view of the prevalence. Waiting for the Saudi National Mental Health Survey’s detailed results, a survey of a nationally representative sample of Saudi citizens aged 15-65 years of common mental disorders, which was conducted between 2011 and 2016, can lighten the road for decision-making and firm actions.44 In response to the increasing prevalence of depression in adolescents, the ministry of education approved the exploratory examination, including screening for depression just before the COVID-19 lockdown and distant learning. The plan was aiming for early detection of depression, the first screening to be for students of the first intermediate grade and first-grade secondary school by using the Quick (PHQ-9 Depression Assessment Questionnaire). The COVID-19 pandemic has increased the current prevalence of depression among youth due to restrictions and prolonged lockdowns. A multi-Arab country study of adolescents found a 57% prevalence of depression with no significant differences between countries.15 Thus, this crisis may increase the current prevalence of depression which requires public health institutes special attention. A systematic review and meta-analysis of the COVID-19 pandemic showed the prevalence of depression in 14 studies with a sample size of 44,531 people (33.7%).45 Once the on-campus education is resumed, screening, intervention, and support should take place.
In conclusion, the significant prevalence of depression among Saudi adolescents is worrisome. Educational institutions should take urgent and firm actions to collaborate with health-care professionals and facilities to reduce the prevalence and control of associated factors, especially after the COVID-19 pandemic. The results obtained from this study would contribute greatly to establishing a sufficient and reliable database about depression, increasing awareness about depression and its associated factors, and promoting adolescents’ mental health in Saudi Arabia. We recommend annual screening for depression to detect the prevalence of depression and to assess the effectiveness of the promotional school programs for mental health.
