ABSTRACT
Objectives: To determine comorbidity of depression and anxiety among
students at the Kenya Medical Training College, Kenya. Methodology:
This was a cross-sectional descriptive study design. Study participants
were basic diploma students in a middle level college in Kenya. Data was
collected using a researcher designed self-administered questionnaire
for socio-demographic characteristics, the Beck Depression Inventory
(BDI) for severity of depression and the Beck Anxiety Inventory (BAI)
for the severity of anxiety in all the students in the seven largest KMTC
campuses. All the participants gave informed consent. Results: 18.4%
and 20.2% of group A and B respectively had moderate depression while
48.5% and 45.8% respectively had severe depression. The equivalents
for anxiety in groups A and B were 24.4% and 23.6% for moderate
anxiety and 32.1% and 31.5% for severe anxiety. There was a higher
rate of depression and anxiety in the second year; with a statistically
significant association between depression and anxiety and the year of
study in the two groups (p<0.0001 each respectively). All the other
social demographic characteristics had no statistically significant
association with depression or anxiety in the two groups. There was a
higher prevalence of depression and anxiety co-morbidity in both
groups which was statistically significant (p<0.0001). Conclusion:
Depression and anxiety were highly prevalent and significantly co- existent among the KMTC students. These mental conditions seemed to
vary with the level of study training among college students. Therefore,
the psychological well-being of college students need to be carefully
addressed. There is need to closely monitor anxiety and depression to
eliminate the risk factors and consequently prevent the development of
adverse outcomes.

INTRODUCTION
Depression and anxiety disorders, either alone or co morbid, are found among the general
population (1, 2, 3). They contribute significantly to the aggregate point prevalence of about 10% of
neuropsychiatric disorders among adults (4, 5, 15).

Depression and anxiety are debilitating. When left unmanaged, they affect one’s general functioning
making it hard for them to perform everyday tasks completely, competently and efficiently (6, 7).
This ultimately affects their general well-being, productivity and quality of life in relation to
themselves and others (8). The average age of onset for many mental health conditions is the typical
college age of 18-24 years.
This is contributed to by the many first encounters in life. Common stressors include: adjustment
to college environment, educational debt, heavy workload, sleep deprivation, difficult patients, poor
learning environments, financial concerns, information overload and career planning, new
friendships, distance from parents, new cultures and alternative ways of thinking (9,10,11,12].
These stressors can lead to catastrophic consequences such as anxiety, depression, impaired
academic performance, impaired competency, medical errors and attrition from medical schools (9,
10, 12, 13). Existence of depression and anxiety among students undertaking health training at
different cadres not only affects the individual’s life negatively but may also have repercussions for
patient care in the long run (14, 15). The medical professionals may become reluctant to be screened
and treated for depression, anxiety or other common mental disorders due to fear of being revealed
that they have the condition(s) and become stigmatised (16, 17,18).
Studies have documented that at the start of medical school, medical students have mental health
similar to their nonmedical peers [16], however, students’ mental health worsens during the
medical training.[14,16,19]
In a study involving 1st and 2nd year medical students in a Californian University to investigate the
use of mental health services and its barriers, Givens et al. (20) found out that about one fourth of
the respondents were depressed. He noted that there was a negative attitude towards mental illness
among the respondents and therefore their unwillingness to openly seek help. He further noted that
medical students encounter severely sick patients many of whom may end up dying. He further
noted that the challenge of dealing with severe illness and death can challenge them emotionally
and may evoke unresolved episodes of loss or trauma from their past and cause them anxiety or
depression.
Givens et al. (20) also found that the students had poor coping strategies in the face of high stress
levels inherent in a student’s life due to inadequate sleep hours, reduced social life, fatigue and
academic challenges involved. As these students encounter serious illness and deaths within their
practical learning sessions, their emotional balance may be put to task and unmask their
vulnerability to either anxiety or depression.
In a cross sectional study to assess prevalence of depression and anxiety among paramedical 1st, 2nd
and 3rd year students of medicine in a Saudi Arabia a significant difference between males and
females was found with 66.6% of the females and 44.4% of the males found to be depressed. Similar
studies found co-existence of depression and anxiety among college students but with no
statistically significant differences between males and females (21).
In a Swedish study (22) to assess the exposure to different stressors and the prevalence of
depression among medical students at different levels of education, the Higher Education Stress

Inventory (HESI), and the Major Depression Inventory (MDI) were used. This study found out that
the prevalence of depressive symptoms among the students was 12.9%, significantly higher than in
the general population, and was 16.1% among female students versus 8.1% among males. Another
study from Turkey used the General Health Questionnaire (GHQ-12) and found out that 47.9% of
the second-year medical students experienced emotional disorders, compared to economics
(29.2%) and physical education students (29.2%). [23] A study from Malaysia also reported that
41.9% of medical students experienced emotional disturbances. [24].
In an earlier study to determine the association and implications of anxiety and depression in
university medical and paramedical students in Kenya, Ndetei et al (25) found 43% of the student
nurses felt they needed to seek help for their symptoms, 14.3% had sought help and there was a
significant correlation between individual symptoms of anxiety and depression in over 50% of all
the pairs of individual symptoms. Out of 364 respondents, 48.9% required medical attention for
their depression and anxiety symptoms. This was the only study found on prevalence of depression
and anxiety among college students in Kenya.
However, there is paucity of information in the literature documenting the prevalence of anxiety
and depression among college students in Kenya. Hence, the aim of this cross-sectional study was
to determine prevalence of depression and anxiety among 1st and 2nd year basic Diploma students
at the Kenya Medical Training Colleges. It was hoped that the study could contribute to the existing
literature on the topic and provide information for possible future interventions.
METHODOLOGY
The study participants were drawn from seven of Kenya Medical Training Colleges. These were: The
Nairobi, Nakuru, Port Reize, Mombasa, Kisumu, Muranga and Meru campuses.
All participants were recruited from seven of the KMTC colleges spread out across the country.
Students involved in the study were pursing any of the courses offered at basic diploma level:
Nursing, Medical Records and information sciences, Community Oral Health, Laboratory sciences,
Public Health Sciences, Medical Imaging sciences, Neurophysiology, Clinical medicine, Dental
technology, Occupational Therapy, Optometry, Orthopaedics Technology, Physiotherapy, pharmacy
and Medical engineering Sciences.
All the students from the colleges who gave informed consent were recruited into the study.
Inclusion criteria was all the 1st and 2nd year basic diploma students in all the academic departments
in the selected KMTCs who gave informed consent while the exclusion criteria was any student in
all the academic departments who was undertaking a post basic course or any 1st or 2nd year student
who had not given consent.
Students were asked to complete self-rated instruments measuring severity of depression and
anxiety as well as a researcher designed questionnaire for socio-demographic characteristics.
Data Collection Instruments
The research instruments consisted of three self-administered questionnaires:

1. A researcher designed questionnaire for Socio-Demographic Characteristics: gender, age,
year of study, marital status, place of residence while in session, religion and the KMTC
campus;
2. The Beck’s Depression Inventory (BDI). This 21 items self-report inventory measures the
severity of depression in a general population in relation to the specified scores. It is a widely
used instrument, discriminates severities of depression, differentiates depression from non- depressed patients and it has a high coefficient alpha of 0.93 (p=0.001) for college students
as well as exhibiting validity and reliability of 90% (25). The cut off points for the BDI used
in this study were 0-9 minimal depression, 10-18 mild depression, 19-29 moderate
depression, 30-63 severe depression.
3. The Beck’s Anxiety Inventory (BAI). This 21 questions instrument was designed to measures
the severity of anxiety in a general population. It has proved to show high interval
consistency and test retest reliability over 1 week (26). In the general population,
respondents who score above 36 scores are considered to have anxiety. The cut off points
for BAI used for this study were 0-7 minimal anxiety, 8-15 mild anxiety, 16-25 for moderate
anxiety, and 26-63 severe anxiety.
The BDI and BAI have been validated against DSM-IV respective diagnostic criteria in the western
countries where they have been used extensively for similar and other relevant surveys as they
were used in this study (26, 27). All the three instruments were self-administered and took an
average of one hour to complete.
Ethical Consideration and data collection procedure
Ethical approval to conduct this study was obtained from Kenyatta National Hospital/University of
Nairobi ethical and research committee. Authority from the Director of KMTC to carry out research
in the selected KMTC campuses was officially communicated to the administrative heads of the
seven selected. All the study participants gave informed consent and confidentiality was maintained
throughout the study. The respondents were all given information on resources available for help.
Data was collected in self-administered questionnaire without any personal identification.
Data management
The collected data was analysed using SPSS version 16, utilizing descriptive and inferential
statistics. Results were presented in the form of tables and narratives. Statistical significance was
set at p < 0.05.

Correlation between the social demographic data with depression and anxiety
Table 3 summarizes the associations between social demographic characteristics and depression
or anxiety in the two groups. There was higher prevalence of depression in the second years
compared to the first years. There was a significant association between level of study and the
prevalence of depression in group A and B, p<0.0001 and p<0.0001 respectively.

carried out in institutions of learning in Kenya found high return rates of up to 100% (28) while
that from a medical University in Karachi was 90% (29). Majority of the respondents were below
24 years and were single since they are admitted in college after their high school examinations and
the majority of those above 24 years and were married, separated, divorced or widowed were
possibly those who were upgrading having undertaken a certificate course and worked for more
than 3 years. More than half of the respondents were Protestants.
Prevalence of depression and anxiety
The reported higher prevalence of depression compared to anxiety in the present study probably
overstates the case for depression and understates for anxiety (29, 30). However, given the fact that
anxiety was independently accessed with BAI, it probably reflects true prevalence of anxiety,
although at the time of the study, the anxiety had possibly already evolved to depression. Anxiety
symptoms are possibly more likely to precede depressive symptoms than the reverse as stated by
Leadbeater, Thompson, & Gruppuso (31). Results on a study on prevalence of depression and
anxiety among medical college students in a Pakistan University found that 70% of the respondents
suffered anxiety and depression which is consistent with what was found in other similar studies
(32,33).
The researchers in these studies concluded that new life styles, financial challenges and psycho
stressors, academic challenges experienced by the respondents might have posed a challenge to
them and precipitated them to develop depression or anxiety. Similar studies explained that the
high levels of severe depression and anxiety found among student respondents could be explained
by the fact students have to deal with unique stressors such as new lifestyles and cultures, new
friends and exposure to alternative ways of thinking. This is because these encounters required
them to develop new strategies to cope with the new circumstances/situations as they progressed
in their professional training and adjust to the new lifestyles different from their socializations.
Those who could not cope were likely to struggle and become susceptible to anxiety and/or
depression (13, 33).
In a similar study to investigate prevalence of depression, anxiety and their associated factors
among medical students in Karachi, a high prevalence, 70%, of anxiety and depression was found
among the respondents. Results indicated that the precipitating causes were not exclusively
academic but included psycho-stressors like loss, relationship problems, residence and substance
abuse among others (29).
In a similar study among Kenyan children and adolescents using the Multidimensional Anxiety Scale
for Children (MASC), 12.9% were found to have clinical anxiety with 80% having social anxiety (28).
Correlation of depression and anxiety with year of study
More 2nd year than 1st year students were found to have severe depression. It was inferred that 2nd
year students had unique issues that were not experienced by their counterparts in their first year.
Since the 2nd year students were undertaking both practical attachments in the various hospitals in
addition to classroom work, exposure to very sick people and death in the hospitals may have
stressed them and precipitated them to develop anxiety or depression. They may also have had no
spare time to get social support of their experiences from their peers because of their busy
schedules in both the classroom and practical learning. In a study by Inam et al (21), it was found
Page 8 of 11

in Social Sciences Research Journal, 7(8) 360-370.
URL: http://dx.doi.org/10.14738/assrj.78.7044 367
out that 66% of the 1st years with depression and anxiety while 73% of the 2nd years had the same.
Other similar studies found similar results (30).
These findings were different from those found in similar studies where 1st year students were
found to have higher prevalence of depression than the 2nd or 3rd years. This was attributed to the
ability of the seniors to cope better with emerging social issues than the 1st years as well as by the
introduction of taking more responsibility for their learning and a shift from the traditional spoon
feeding teaching methodology (31). The drop of prevalence rate in 2nd year may support the above
hypothesis since by then the students get used to the system (13, 14, 16).
The study found out that there were more males with depression compared to females while
prevalence of anxiety was similar among males and females is probably because females are more
likely able to cope better with possible psycho stressors since they are by nature more expressive
of their challenges and therefore more likely to get social support (21, 23). There may have been
other factors that caused more males than females to develop depression that were less prevalent
among the females. For instance, males having more risk to substance abuse than the females, which
may have predisposed them to develop substance-induced depression or anxiety as found in other
studies (34, 35). Other studies however have found more females with depression and anxiety than
the males.
Bazmi (38) in a similar study found 66.6% of the females with depression and anxiety while 44.4%
males had the same and there was a statistically significant difference of p=0.001. This could have
been due to more females complaining about the volume and complexity of the academic material
they had to cover or females were likely to report stress or a tendency of females to over report
medical and psychological symptoms. Nonetheless, male bias towards female complaints cannot be
ruled out. However, in our study, since the questionnaire was self-administered and anonymous,
therefore, further workup could not be carried out to tease out the factors related to higher reported
levels of anxiety and depression in females.
The higher percentage of respondents above 25 years in this study who had severe depression
compared to the younger age groups and the similar trend observed on the correlation between
anxiety and age group is probably because; those above 25 years were in their 2nd year of study
which posed greater academic demands, financial challenges or social/family related challenges
since they may have been married, divorced or widowed which meant added responsibilities as
they studied. It was observed that respondents who were from the Nairobi campus might have had
additional challenges of the city life compared to respondents who were drawn from KMTCs in less
hectic rural towns. These results were different from those of other studies where the younger age
groups were found to have higher levels of depression and anxiety (28) while other studies found
similar results (9, 20, 29).
The higher levels of depression among group the Nairobi Campus respondents who resided outside
the college hostels compared to those who resided in college hostels can be associated with more
challenges they encounter compared to students in peripheral campuses: The financial burden in
Nairobi city is much more than in the rural towns, notwithstanding the logistics of transportation
from their places of residence to college as compared to the other KMTCs located in less hectic and
Page 9 of 11

in-expensive towns. This study did not seek to investigate specific possible psycho stressors that
may have precipitated the respondents to develop these conditions.
Co-morbidity between depression and anxiety
The high co-morbidity of depression and anxiety found in this study is similar to findings in other
studies (29, 38, 40), leading to the conclusion that cases of pure depression without anxiety were
rarer than cases of anxiety without concomitant depression (35, 36, 37), including the case of
students in colleges due to the new exposures that student’s encounter (35,39).
This study contributes to the global data base in general and the first Kenya data specifically on
scientifically based evidence on the high prevalence of depression and anxiety among these young
adult paramedical students. The results of the study provide baseline data for the institution’s
management to make evidence based policies for prevention, management and unveiled mental
health training needs for the students. This would in turn pave way for possible scientifically based
decisions to review the various curricula to incorporate a mental health component in all the
academic departments.
LIMITATION OF THE STUDY
A limitation of the current study is that it did not investigate whether or not any respondent had
suffered depression or anxiety previously as well as indentify definite possible psycho stressor,
which may have precipitated depression or anxiety.
