Abstract
Background: Condoms offer the best protection against unintended pregnancies and sexually transmitted
infections Little research has been conducted to determine the prevalence and investigate the influencing factors
of condom use at first sexual intercourse among college students
Methods: A self-administered questionnaire was completed by 1137 college students (573 male and 564 female)
in the Kathmandu Valley Analyses were confined to 428 students who reported that they have ever had sexual intercourse The association between condom use at first sexual intercourse and the explanatory variables was assessed in bivariate analysis using Chi-square tests The associations were further explored using multivariate logistic analysis in order to identify the significant predictors after controlling for other variables
Results: Among the sexually active students, less than half (48%) had used condoms during first sexual intercourse The results from the logistic regression analysis revealed that age, caste and/or ethnicity, age at first sexual
intercourse, types of first sex partner, alcohol consumption and mass media exposure are significant predictors for condom use at first sexual intercourse among the college students Students in the older age groups who had first sex were about four times (16 to 19 years old) (OR = 3.5) more likely and nine times (20 or older) (OR = 8.9) more likely than the students who had sex before 16 years of age to use condoms at first sexual intercourse
Moreover, those students who had first sex with commercial sex worker were five times (OR = 4.9) more likely than those who had first sex with their spouse to use condoms at first sex Furthermore, students who had higher exposure to both print and electronic media were about twice (OR = 1.75) as likely as those who had lower media exposure to use condoms On the other hand, students who frequently consumed alcohol were 54% (OR = 0.46) less likely to use condoms at first sexual intercourse than those who never or rarely consumed alcohol
Conclusions: The rate of condom use at first sexual intercourse is low among the students It indicates students are exposed to health hazards through their sexual behaviour If low use of condom at first sex continues,
vulnerable sexual networks will grow among them that allow quicker spreading of sexually transmitted diseases and HIV Findings from this study point to areas that policy and programmes can address to provide youth with access to the kinds of information and services they need to achieve healthy sexual and reproductive lives

Trang 2The Federal Democratic Republic of Nepal is a
land-locked country in south Asia It lies between the two of
the most populous countries of the world: China in the
north and India in the south, east and west These
countries are ranked as the first and the second largest
countries of the world, respectively, in size of
popula-tion The total population of Nepal was 27.5 million in
2009 [1] About one in five of Nepal’s people are in the
age group of 15 to 24 years [2]
HIV/AIDS has become a global problem and has
spread all over the world The latest statistics estimate
that approximately 33.4 million people worldwide were
living with HIV/AIDS by the end of 2008 Of these, 4.7
million people were in Asia India, Nepal’s neighbour,
accounts for roughly half of Asia’s HIV prevalence
With the exception of Thailand, every country in Asia
has an adult HIV prevalence of less than 1% However,
owing to the region’s large population, Asia’s
compara-tively low HIV prevalence translates into a substantial
portion of the global HIV burden in terms of numbers
[3]
Like other countries in Asia, Nepal is susceptible to
HIV The country is indeed facing critical challenges
posed by the rapid spread of HIV/AIDS By October
2009, about 15,000 cases of HIV infection and about
2600 cases of AIDS had been officially reported Among
these HIV cases, more than two in five cases (41%) were
in the college/university-going (15-29 years) age group
[4] However, given the limitations of Nepal’s public
health surveillance system, the actual number of
infec-tions is thought to be much higher The Joint United
Nations Programme on HIV/AIDS (UNAIDS) estimated
that 75,000 people were living with HIV at the end of
2007 [5] It has been found that one in every 200 young
males (0.5%) and one in every 300 females (0.3%) aged
15 to 24 are infected by HIV in Nepal [1]
Studies show that college students engage in a variety
of behaviours that put them at risk for serious health
problems [6,7] College students are at risk of sexually
transmitted infections, including HIV, due to their
pro-pensity to take risks, often with multiple partners,
accompanied by an inconsistent use of condoms [8,9]
Ample research has also examined the prevalence of
excessive alcohol and other substance use, risky sexual
behaviour, and other harmful health behaviours that are
not uncommon among college students [10-13]
Similarly, a study found that young adults represent
one of the groups at highest risk for HIV infection [14]
A study conducted in colleges in Nepal showed that
about two in five male college students (39%) had
pre-marital sexual experiences Among these, more than half
reported that they had multiple sex partners
Furthermore, more than one in five (23%) had sexual experience with commercial sex workers, and less than half of them (49%) had used condoms in every act of sexual intercourse with a sex worker [15] Such risky sexual behaviour increases the risk of contracting an STI or HIV which jeopardizes academic achievement and performance of the students [13,16,17]
Differences in levels of condom use in various popula-tion groups and settings have been identified in the lit-erature In particular, groups with the lowest levels of education have consistently been the least likely to use condoms, both with non-marital and marital partners [18-22] Some studies also revealed an increase in con-dom use in the younger age groups [18,23,24] compared
to the older groups Some studies found that later sexual activity has also been associated with an increased use of condoms [25-27] Furthermore, alcohol use is highly prevalent among college students, and contributes to rising rates of sexual risk taking [28-31] Empirical evi-dence also suggests that the mass media has an impor-tant role in shaping individual reproductive attitudes and behaviours [32-34] In fact, the mass media variable
is a reliable predictor of condom use among individuals [35,36] One study showed that men who heard about AIDS through either electronic or print media were 30%
to 50% more likely to have used a condom than men not exposed to these media [37]
Many researchers and public health policy makers are particularly interested in the subject of first sexual con-tact A person’s first sexual intercourse often occurs before the age of 20 This is linked to two factors: the association between behaviours in the first sexual rela-tionship and the establishment of behavioural patterns throughout life [38-40]; and the recognition that sexual initiation at a very young age is a risk factor for preg-nancies before the age of 20 and acquiring sexually transmitted diseases, including HIV [26,41]
Condom use at first sex is easily remembered Some studies have found a strong link between first condom use and lifetime use: a 20-fold increase in lifetime use and a 10-fold increase in current use if a condom was used at first sexual contact [42] There is a limited body
of literature that points to condom use at first sexual contact among young people, especially students, and none of the studies has analyzed the data on condom use at first sex in Nepal
It is useful to know about condom use during first sexual intercourse in Nepal so that priorities and approaches for interventions to prevent risky sexual behaviour can be better designed This article aims to determine the prevalence of and investigate the factors associated with condom use at first sexual intercourse among college students in Nepal
Trang 3Specifically, it is assumed that students who have sex
at an earlier age, who consume alcohol frequently, who
have sex with irregular partners, and who have lower
exposure to mass media use condoms less at first sexual
intercourse The findings of this study address the gap
in knowledge by providing the information on condom
use at first sexual intercourse that could assist
pro-gramme managers of government agencies and
non-governmental organizations and the Government of
Nepal in designing appropriate and timely
education-based interventions in institutions of secondary and
higher education
Methods
Data and sampling framework
The data used in this paper comes from a
cross-sec-tional survey on attitude and behaviour towards
premar-ital sex among college students of Kathmandu, the
capital of Nepal, carried out in 2006 The survey
involved a total of 1137 students (573 male and 564
female) studying in 12 colleges affiliated to Tribhuvan
University in Kathmandu Analyses were confined to
428 students who reported that they have ever had
sex-ual intercourse The scientific committee, which
included the Ethical Review Board of the University
Grant Commission in Nepal, approved the proposal and
provided funding for this study
A two-stage random sampling technique was applied
The first stage included a random selection of 12
col-leges in Kathmandu In order to select these colcol-leges, a
list of all the private and public colleges affiliated with
Tribhuvan University and located in the Kathmandu
Valley (which includes three districts: Bhaktapur,
Lalit-pur and Kathmandu) was obtained from the office of
the Vice Chancellor in Kathmandu This list included
colleges that provide intermediate (commonly known as
Grades 11 and 12), undergraduate and graduate degrees
In the second stage, two classes were randomly selected
from each sampled college The number of students in a
class ranged from 40 to 60 All the colleges are
co-edu-cational, and all male and female students present on
the day of the interview in the sampled classes were
requested to participate in the study
Research instrument and data collection
Due to the sensitive nature of the study and the
educa-tional background of the respondents, a
self-admini-strated, structured questionnaire in the Nepali language
was used to obtain information The questionnaires
were first developed in English and then translated into
Nepali Almost all sections pertaining to the behavioural
aspect were based on Behavioral Surveillance Survey
questionnaire developed by Family Health International/
Impact [43] However, necessary modifications were
made to suit the sample population The questionnaires were pre-tested among students in a college that had not been selected as part of the study, and later refined
as required The pre-test was conducted to determine whether the questionnaires were in sequential order and the wording in Nepali was understandable or not Most
of the questions were close ended; a few open-ended questions were also included
Female and male students filled in the questionnaire separately in different classrooms Each student was allocated a separate bench, as in an exam setting, before the questionnaire was distributed to them A male researcher supervised the male students’ class while a female researcher supervised the female students’ class Students were then requested to place the filled-in ques-tionnaire on a table in the corner of each class
Ethical considerations
Before starting the study in a sampled college, approval from the campus administrative authority was obtained All the participants involved in the study were fully informed about the nature of the study, the research objectives, and the confidentiality of the data After this, verbal consent was obtained from the participants before they were enrolled in the study The consent form was also written in the local language, stating the study’s objectives, nature of the participant’s involve-ment, risk and benefits, and confidentiality of the data Students were requested to read the consent form care-fully They were given clear options on voluntary parti-cipation It was also made clear that they could refuse
to answer any of the questions and terminate the inter-view if and when they desired
All of the approached students agreed to participate in the study Confidentiality of information was ensured by removing personal identifiers from the completed ques-tionnaires The names of sampled colleges were not made public and thus, it is not possible for anyone out-side the research team to trace reported incidents of sexual behaviour to respondents Respondents were thus protected from any possible adverse repercussions of participating in the study
Variables
The measurable outcome of the study is condom use at first sexual intercourse, a dichotomous variable indicat-ing whether or not the respondent had used a condom during the first sexual encounter
The independent variables used in the study were: sex
of the respondent; age; caste and/or ethnicity; level of education; age at first sexual intercourse; marital status; types of first sexual partner; permanent place of resi-dence; alcohol consumption; mass media exposure; and living arrangement All these variables were organized
Trang 4into two or three categories, based on those used in
other literature, as well as on the frequency distribution
of the variables
The indicators of exposure to mass media include an
exposure to radio, television and newspapers The
majority of the students rent rooms in the Kathmandu
Valley so it is assumed that not all of them have TVs in
their rooms Thus, radio and TV were combined and
treated as electronic media, and newspaper as print
media Almost all students were exposed to at least one
type of media (either electronic or print) Because of
this, the mass media variable was organized into two
categories If a student was exposed to only one type of
media, it was considered as low exposure; if a student
was exposed to both print and electronic media, it was
considered as high exposure
Similarly, some ethnic groups in Nepal offer alcohol to
the gods in religious ceremonies, and people have to
consume alcohol in these ceremonies Therefore, this
variable was categorized into two: (1) never/rarely
con-sume alcohol and (2) frequently concon-sume alcohol (two
or three times a week)
The variable,“living arrangement”, is also organized
into two categories: those students who live with their
family members were considered as “with biological
family"; those who live away from family members were
considered as “without biological family” The other
independent variables were categorized in the same way
Methods of analysis
All completed survey questionnaires were entered into a
database after manual coding and validation Data entry
and validity checks were performed for all the
question-naires by using the computer software programme,
dBase IV The cleaned and validated data was
trans-ferred into the SPSS software programme for further
processing and analysis
Both bivariate and multivariate techniques were
applied in the analysis The Chi-square test was used to
test the association between the variables Those
vari-ables that were significant in the bivariate analysis were
further reexamined in the multivariate analysis (binary
logistic regression) in order to identify the significant
predictors after controlling for other variables Before
the multivariate analysis, multicollinearity among
vari-ables was assessed, and the least important variable,
which was highly correlated to other variables, was
removed from the logistic model
Results
Characteristics of the respondents
Among the students, about two in five (39%) (47% boys;
28% girls) had sexual intercourse irrespective of their
marital status Among these sexually active students
(n = 428), around 27% were aged 15 to 19 Eleven per-cent reported that they had had sex before the age of
16 A large majority of the sexually active students were from outside of the Kathmandu Valley More than a third (34%) of the students consumed alcohol frequently (two or three times a week) Almost half of the students resided with their biological families Almost all students were exposed to at least one type of mass media (either electronic or print) Furthermore, both male and female college students were generally aware of HIV/AIDS and knew of at least one mode of transmission of HIV/AIDS (data not shown)
Socio-demographics correlate with condom use
Among the sexually active students, just less than half (48%) had used condoms during their first sexual tacts Table 1 shows the clear association between con-dom use at first sexual intercourse and different socio-demographic characteristics Of those who used con-doms at their first sex, a significantly higher proportion than their comparison group: were males; were aged 15
to 19; were from the Brahmin and Chhetri communities; had first sex at age 16 or older; were unmarried; had sex with a boyfriend/girlfriend; were from outside the Kath-mandu Valley; had high exposure to the mass media; and lived with their biological families (Table 1)
Binary logistic regression analysis was used to measure the strength of the association between various indepen-dent variables and the probabilities of using condoms at first sex Only those variables that had significant asso-ciation in bivariate analysis were reassessed in the logis-tic model Before the multivariate analysis, multicollinearity among the variables was assessed It was found that the variables,“marital status” and “types
of first sex partner”, were highly correlated (r = 0.7) Therefore, the variable, “marital status”, was not included in the logistic model
Analysis from logistic regression showed that age group, caste and/or ethnicity, age at first sexual inter-course, types of first sex partner, alcohol consumption, and mass media exposure were significant predictors for condom use at first sexual intercourse Students aged 20 or older were less likely to use condoms (OR
= 0.40) than students aged 15 to 19 Similarly, students from castes other than Brahmin and Chhetri were 40% (OR = 0.60) less likely to use condoms during their first sexual intercourses than those from other castes and ethnic groups Furthermore, students who had sexual intercourse for the first time in the age groups
of 16 to 19 and 20 or older were almost four times (OR = 3.5) and nine times (OR = 8.9) more likely, respectively, than students who had first sex before
16 years to use condoms at first sexual intercourse (Table 2)
Trang 5Those students who had first sex with a commercial
sex worker were about five times more likely than those
who had first sex with their spouse to use condoms
dur-ing first sexual intercourse An inverse relationship was
observed between alcohol consumption and condom
use Those students who had frequently consumed
alco-hol were 54% (OR = 0.46) less likely to use condoms at
first sexual intercourse than those who did not consume
alcohol On the other hand, students who had higher exposure to both print and electronic media were about twice (OR = 1.75) as likely as who had lower media exposure to use condoms during their first sexual inter-courses (Table 2)
Discussion
This study shows that condom use at first sexual inter-course is low among college students in Kathmandu, Nepal If condom use at first sex remains low, vulner-able sexual networks will grow among the students, allowing faster spreading of sexually transmitted diseases and HIV Our study found that condom use at first sex-ual intercourse varied according to different criteria Age group, caste and/or ethnicity, age at first sexual intercourse, types of first sex partner, alcohol consump-tion and mass media exposure were significant predic-tors for using condoms at first sexual intercourse

Trang 6The study also found that students aged 15 to 19 were
more likely to use condoms during first sexual
inter-course compared with students aged 20 or older Results
from this study are consistent with those of many other
studies [18,23,24] The finding of this study was also
consistent with that of other literature: that later sexual
intercourse has also been associated with increased use
of condoms [25-27]
Many other studies have found significant differences
in condom use according to the type of relationship
with sex partners, defined as casual or fixed/steady
[44-46] Our study also supported the finding of other
studies that the level of condom use is higher in those
who had first sex with casual or non-steady partners
than in those who had first sex with spouses or steady
partners Regarding alcohol consumption, results from
this study are similar to most other studies: alcohol use
contributes to a lower use of condoms and elevated
rates of sexual risk [28-31]
Mass media exposure is another important predictor
for condom use at first sexual intercourse Those
stu-dents who were exposed to both electronic and print
media were more likely to use condoms than those who
had low exposure to these media This finding is similar
to that of other studies [35,36] Diffusion theorists
pos-tulate that the mass media effect contraceptive use by
stimulating partners to discuss contraceptive use [47]
Through the sharing of information and mutual
feed-back, people give meaning to information, understand
each other’s views and influence each other [48] Thus,
discussion of contraceptive use leads to the development
of a better understanding between partners of their
reproductive health goals
There are some limitations to this study First, because
of the cross-sectional design of the study and the nature
of the items used in the logistic regression analysis, the
analysis can only provide evidence of statistical
associa-tion between those items and condom use at first sex
and can not show cause-effect relationships Second, all
measures were self-reported Thus, responses may have
been biased by recall errors or intentional misreporting
of behaviour However, the privacy conditions around
the study and the use of self-administered
question-naires are likely to have minimized purposeful
misreporting
Conclusions
The rate of condom use at first sexual intercourse is low
among the students It indicates students are exposed to
health hazards through their sexual behaviour If low
use of condoms at first sex continues, vulnerable sexual
networks will increase among the students, allowing
more growth in the spread of sexually transmitted
dis-eases and HIV
Our study showed a positive effect of the mass media
on condom use at first sex; information about condom use and sexual risk behaviour, including unsafe sex, should be provided through the mass media Similarly, students who had sex at a later age were more likely to use condoms at first sex Therefore, awareness pro-grammes that encourage postponement of sexual debuts could benefit the students Findings from this study point to areas that policy and programmes can address
to provide youth with access to the kinds of information and services they need to achieve healthy sexual and reproductive lives
