Depression among students
Introduction:
Depression among university students is extremely prevalent
and widespread problem across the country [1–3]. University students are a
special group of people that are enduring a critical transitory period in which
they are going from adolescence to adulthood and can be one of the most
stressful times in a person’s life. Trying to fit in, maintain good grades,
plan for the future, and be away from home often causes anxiety for a lot of
students [4]. As a reaction to this stress, some students get depressed. They
find that they cannot get themselves together. They may cry all of the time,
skip classes, or isolate themselves without realizing they are depressed.
Previous studies reported that depression in university students is noted
around the world [5–7] and the prevalence seems to be increasing [8]. The
average age of onset is also on the decline, making depression a particularly
salient problem area for university student populations [8]. Over two-thirds of
young people do not talk about or seek help for mental health problems [9]. In
Iran, preliminary studies on emotional distress have emerged in recent years
including depression in Iranian university. Within the abovementioned
background, the aim of this study is to estimate the prevalence of depression among
university students using meta-analysis method.
Students’ age and depression :
In terms of students’ age, some studies in particular looked
at the relationship between age and depression in students. A study on
depression among Malaysian university students pointed out that the prevalence
of depression was higher in older students compared to younger students
(Shamsuddin et al., 2013). This result also was emphasized in other studies;
senior university students have greater rates of depression relative to
beginners or first year students (Bostanci et al., 2005; Khawaja &
Duncanson, 2008). In contrast, studies in this area (Bayram and Bilgel, 2008;
Tomoda et al., 2000) have shown that students in their final year of university
have lower levels of depression compared to new students. It is hypothesised
that this difference in the above findings might be due to using different
samples of students, and different methods of measuring depression. It is
somewhat surprising that no relationship was found in this condition. One study
indicated that the level of depression in older students is nearly the same as
younger students (Lester, 1990). This would indicate there is no significant
relationship between a student’s age and the prevalence of depression.
Prevention of depression:
Depression is one of
the most prevalent problems in the mental health of students at different
educational levels, such as high school, college and university (Arslan et al.,
2009). Previous studies have proposed that psychological morbidity,
particularly depression, is a common disorder among students (Adewuya, Ola,
Olutayo, Mapayi & Oginni, 2006; Dahlin et al., 2005). Studies of
psychological problems encountered by counselling centres revealed that
depression was one of the five most common problems among college students.
They highlighted that depression accounted for 39% of problems, a higher rate
than anxiety, problems with romantic relationships, and the self-esteem of
students across different settings (Erdur-Baker, Aberson, Borrow & Draper,
2006; Green, Lowry & Kopta, 2003).

of the four major diseases in the world and is the most common cause of
disability from diseases. The aim of this study is to estimate the prevalence
of depression among Iranian university students using meta-analysis method.
Materials and Methods. Keyword depression was searched in electronic databases
such as PubMed, Scopus, MAGIran, Medlib, and SID. Data was analyzed using
meta-analysis (random-effects model). Heterogeneity of studies was assessed
using the 𝐼 2 index. Data was analyzed using
STATA software Ver.10. Results. In 35 studies conducted in Iran from 1995 to
2012 with sample size of 9743, prevalence of depression in the university
students was estimated to be 33% (95% CI: 32–34). The prevalence of depression
among boys was estimated to be 28% (95% CI: 26–30), among girls 23% (95% CI:
22–24), single students 39% (95% CI: 37–41), and married students 20% (95% CI:
17–24). Metaregression model showed that the trend of depression among Iranian
students was flat. Conclusions. On the whole, depression is common in university
students with no preponderance between males and females and in single students
is higher than married ones.
Methodology:
This study protocol is structured in accordance with the
Preferred Reporting Items for Systematic reviews and Meta Analyses (PRISMA).
The PRISMA contains a 27-item checklist which is aimed at facilitating the
development and reporting of robust systematic review protocols [20]. The
systematic review was registered on the PROSPERO database (CRD42017064148). Information
sources Pub med, Psych INFO, EMBASE and African Index Medicus , BIREME, LILACS,
and MEDLINE databases will be searched for studies reporting primary data on
common mental disorders (depression and/or anxiety) among students in
universities and colleges within LMICs. For this study, LMICs will be defined
using the World Bank Country Lending Group list for the year 2017 [21]. Search
strategy In light of the paucity of studies in LMICs, no time restrictions will
be imposed on the search. Controlled vocabulary terms will be appropriately
incorporated for each database. We will use the terms to search for three main
concepts namely (1) undergraduate university/college students, (2) prevalence
of depression or anxiety, and (3) low- and middle-income countries. A full
search strategy for one database is displayed in Appendix 1. Reference lists of
retrieved articles will also be examined and additional articles added if they
meet the inclusion criteria. Eligibility criteria Studies will be included if
they report the prevalence of depression or anxiety among university/college
students undertaking undergraduate degree programs. Study types will include
descriptive and analytical studies such as cross-sectional and longitudinal
studies, case-series analysis, and randomized control trials that include data
on prevalence of depression or anxiety. We will include studies in all
languages, which will be translated into English. Due to paucity of research on
depression or anxiety in most LMICs, the studies will not be excluded based on
how they measured depression or anxiety since it is important to understand how
these conditions are being measured in different settings.
Data extraction;
Two reviewers will independently screen titles and then
abstracts of included articles using a piloted data extraction sheet (Appendix
2). Examples of the type of data that will be extracted include study design,
setting, study sample sizes, assessments used for diagnosing depression or
anxiety, and prevalence of depression or anxiety. Where there will be doubts on
whether a title is relevant, it will be included for retrieval. Reconciliation
of disagreements on which article(s) to include will be resolved by discussion
and consensus between the two reviewers, or mediation by a third person.
Assessment of methodological quality
Assessment of methodological assessment;
All retrieved papers eligible for selection will undergo an assessment
process conducted by two independent reviewers. Standardized critical appraisal
tools will be utilized in the quality assessment. In this study, four critical
appraisal tools [22] will be used to assess for quality depending on the study
design. These are as follows: 1. The Joanna Briggs Institute (JBI) Prevalence
Critical Appraisal tool [23] 2. The JBI critical appraisal checklist for
randomized control/pseudo-randomized trials 3. The JBI critical appraisal
checklist for descriptive/case series 4. The JBI critical appraisal checklist
for comparable cohort/case control. These tools were developed primarily for
use in systematic reviews. Where there are disagreements between the two
reviewers, a third reviewer will be engaged and discussions among the three
reviewers will be used to resolve the differences.
Data analysis;
Data analysis and synthesis Meta-analysis of the prevalence
of depression and anxiety among university students will be conducted using a
random effects model which will generate pooled prevalence with their respsiective
95% CIs. Analyses will be conducted in Stata 14. The results from the review
will be summarized and presented in text, Appendix 3, and tables.
Statistical analysis;
The random effects model was used for combining results of
studies in meta-analysis. Variance for each study was calculated using the
binomial distribution formula. The presence of heterogeneity was determined by
the Der Simonian -Laird (DL) approach [12]. Significance level was < 0.05
were considered as statistically significant.
Discussion:
This systematic review will be conducted as the initial step
of a longitudinal study on common mental disorders among university students in
Zimbabwe. The review aims to explore the prevalence, antecedents, and
consequences of depression and anxiety among university students in LMICs. The
results from the review will inform and guide health care practitioners and
researchers on appropriate and feasible interventions aimed at enhancing the
psychological well-being of undergraduate students in resource constrained
settings. In this systematic review, we have fully described our search
strategy, study selection, data summary, and analysis to allow sensitivity
analysis of any aspect of our approach. We have included every study that to
our knowledge satisfies our inclusion criteria and employed techniques of
estimation that allow integration of studies with high heterogeneity. In
situations with high between-study heterogeneity (93.3%), the use of
random-effects models is recommended as it produces study weights that
primarily reflect the between study variation and thus provides close-to-equal
weighting. In the current study, the Beck depression inventory (BDI) has been
utilized to detect the prevalence of depression among university students.
Although it is not designed for diagnostic purposes, its epidemiologic utility
has been evaluated in several studies, which concluded that it is a reliable
and valid instrument for detecting depressive disorders in nonclinical
populations. Several studies support the BDI’s usefulness in measuring and
predicting depression in adolescent samples.
