Evaluation of uptake and attitude to voluntary counseling and testing among health care professional students in Kilimanjaro region, Tanzania

Background Voluntary counseling and testing (VCT) is a corner stone for successful implementation of prevention, care and support services among HIV negative and positive individuals. VCT is also perceived to be an effective strategy in risk reduction among sexually active young people.. This study aimed to assess the acceptability of VCT and its actual uptake among young health care professional students at KCM College of Tumaini University and Allied health schools. Methods This was a cross-sectional study. A structured questionnaire was used among health care professional students aged 18–25 years who were enrolled in degrees, diplomas and certificates courses at Kilimanjaro Christian Medical College and all other Allied health schools Results A total of 309 students were recruited, among these 197 (63.8%) were females. All respondents were aware of the benefits of VCT. Only 107 (34.6%) of students have had VCT done previously. About 59 (19.1%) of the students had negative for health care professional to attend VCT. Risk perception among the students was low (37.2%) even though they were found to have higher risk behaviors that predispose them to get HIV infection. Conclusion Awareness of VCT services and willingness to test is high among students; however its uptake is low. In order to promote these services, a comprehensive training module on VCT needs to be included in their training curricula. In particular, more emphasis should focus on the benefits of VCT and to help the students to internalize the risk of HIV so that they can take preventive measures.

Currently, there is no cure or vaccine for HIV/AIDS; however, the provision of Antiretro viral drugs and positive prevention strategies helps to prolong life for those who are already infected. Many countries have been trying to take many different approaches in an attempt to slow the spread of HIV infection and minimize its impact on the individual, family and society. Among these strategies include; voluntary counseling and testing (VCT), provider initiated counseling and testing (PICT), diagnosis of HIV in infants and young children, family care and partner testing and counseling based on index care, condom promotion and provision, detection and management of sexually transmitted infections, safer sex and risk reduction counseling, male circumcision, targeted interventions for sex workers and men who have sex with men (homosexual practice). Others include; occupational and non occupational post exposure prophylaxis, family planning and counseling, antiretroviral medicines for preventing HIV infection in infants, treatment, care, support for pregnant HIV positive women, infant feeding counseling and support, prevention of HIV from mothers to children and pre-vention of HIV (and tuberculosis) transmission in health care settings (Infection control), blood safety, safe injections and use of standard precautions. All these strategies emphasizes on behavior change and risk reduction behavior which both adult and youth have shown to have positive response to VCT [4] In Tanzania voluntary counseling and testing activities started in 1997, by the end of April 2008 about 5,319,247 clients were counseled and tested for HIV in 1643 HIV voluntary counseling and testing centers in the country [5].
Health care professional students are not spared with the increased HIV infections because majority of them fall under the age group which are at risk of HIV infection and occupational exposure [6]. In addition, the public expect the medical professionals to be seen as a role model in health care seeking behaviour including VCT.
It was the objective of this study to assess the acceptability of VCT among the vulnerable group of health care professional students (18-25 years) at KCM College of Tumaini University and other health allied schools in the campus in Moshi town. The information that generated from this study for will be useful to health policy makers in developing HIV/AIDS interventions, curriculum development and provision of youth friendly services

Study Design
A cross-sectional survey was conducted between April and May 2005.

Study Area
The study was conducted at KCM College and other affiliated allied Health Schools at Kilimanjaro Christian Medical Centre. The Kilimanjaro Christian Medical College is incorporated in the Kilimanjaro Christian Medical Center, a research and teaching hospital. It is one among the fourreferral hospitals in the country being situated in Moshi urban district, which is one of the six districts of Kilimanjaro region in North Eastern part of Tanzania.
There are about eight voluntary counseling and testing centers in Moshi Municipality, most of them located in town, and these includes, Kinshai, Langani, KCMC-Mbuyuni, Mawenzi Hospital, Rainbow, Pasua Health Center, KCMC and "KIWAKKUKI". KIWAKKUKI is a female non governmental organization which stands for "women association to fight against HIV/AIDS Kilimanjaro

Study Population
This study targeted health care professional students undertaking degrees, diplomas and certificates courses at KCM College and all other Allied Health Schools at Kilimanjaro Christian Medical Center campus, student aged 18-25 years. (According to Tanzanian law, an adult is said to be anybody aged 18 years and above. These can give consent on their own without soliciting permission from parents or teachers).

Sampling Frame
We only aimed to recruit students within the ages 18 to 25 years from 18 Schools in KCMC campus including KCM College. Therefore, all students aged between 18-25 years were eligible for this study, those who consented for the study, those studying at KCM College and other Allied Health Schools at KCMC campus and who were able to speak either Kiswahili or English language. The exclusion criteria for the study were; students who were either below or above 18-25 years age group, student's who did not consent to participate in the study, students who were not from KCMC or from any of the Allied Health Schools at KCMC campus and those Students who could not communicate either in English or in Kiswahili language Out of 780 total number of KCMC students, only 420 students were eligible for this study. A convenience sampling method was used to select the study participants. Only students who were available during the class sessions were selected. The author administered questionnaires to all eligible participants. The questionnaires were retrieved from 309 students, the rest 11(2.6%) did not return the questionnaire to the author.

Data Collection
Structured questionnaire was prepared to capture the relevant information based on the study objective. Questionnaires are initially administered to similar respondents in a non-participating institution for validation.
The investigator visited each school in the study area. A specific day and time for each school was arranged in order to meet students in their respective classrooms in order explain the study objective.

Data Management and Analysis
Data base was made in MS-access. Data entry was done in duplicate for validation (double entry). Before analysis, data were cross-checked for entry error and range checks. Analysis was done using SPSS version 15.0 for windows. Descriptive statistics were obtained for different quantitative variables. Frequencies and percentages were used to present categorical variables. Furthermore, cross tabulations were done to determine some significance of associations between variables, where Chi Squared test and their respective p-values were calculated. The p = 0.05 (2-tailed) was used as a cut-off point to test statistical significances between variables compared.

Ethical Issues
Ethical clearance was obtained from KCMC ethical committee.
Permission to conduct this study was obtained from the Provost of KCM College of the Tumaini University and Principals of all Allied Health sciences schools at KCMC campus. Individual consents were sought from the study participants before starting the study; participants were requested to sign the consent forms after they had understood the study aims and before answering the questions. Participants were also informed that participation was on voluntary basis. Confidentiality was assured, where anonymous questionnaires were used. Students who were not selected in the study were told the reason for their ineligibility.

Demographic characteristic of the study population
A total of 309 (96.6%) health care professional students from different health schools at KCMC were enrolled in the study. The mean age and standard deviation for male and female were 23.7 ± 1.46 and 23.3 ± 1.68 years respectively. There were 112 (36.2%) males and 197 (63.8%) females, giving a sex ratio of 1:1.8. Most of the study participants were single 294 (95%).

Risk assessment
A higher proportion of males 110 (98.2%) reported to have had sexual experience compared to 190 (96.4%) Females were two times more likely to be at high risk compared to their males counterpart (χ 2 = 6.7, p = 0.01). In contrast, females were more likely to have one current sexual partner compared to males. This difference was statistically significant (χ 2 = 6.17, p = 0.01).
The reported age of sexual debut ranged between 6 to 20 years with the mean age of 11.26 ± 3.6 years ( Table 1). There was no difference in mean age at sexual debut between the two sexes.
About 25% of the sexually active group had experienced sexual intercourse by the age of 9 years, 50% by the age of 12 years and 75% by the age of 14 years. Males reported to engage in sex more than females. However, the difference was not statistically significant (χ 2 = 2.8, p = 0.1). Males were more likely to have sex after 18 years of age compared to females. The difference was statistically significant with (χ 2 = 4.8, p = 0.03).
Students in the age group 24-25 years had slightly higher proportion (49.8%) of being sexually exposed compared to other age groups. In addition, the age group 22-23 years (35.0%) had sexual exposure while for the youngest age group 18-21 years only (15.2%) had sexual exposure in their lifetime. However the differences were not statistically significant (χ 2 = 2.5, p = 0.28).
The characteristics of sexually active participants are shown in table 2. Among 300 students who responded to the question on the number of their sexual partners, majority 196(65.3%) reported having multiple sexual partners; female were 1.9 times more likely to have multiple sexual partners compared to males (χ 2 = 6.17, P = 0.01).
Regarding the risk perception, students were asked to grade their risk as being high, low and no risk (  Those who have not perceived higher risk due to history of STIs 54(47.0%) reported more of contracting HIV as compared to 60 (30.9%) students who never had history of STIs (χ 2 = 7.29, P = 0.007). There was a statistically significant difference in risks of contracting HIV for 65 (78.3%) students who perceived higher risk following the use of Narcotic drugs compared to 50 (22.1%) students who never abuse Narcotics. (χ 2 = 79.64, P ≤ 0.001).
We also observed the statistical significant difference in risk perception. Students who reported to have sex under influence of alcohol 75 (48.1%) were perceived to have high risk compared to those who never had sex under the influence of alcohol 40 (26.1%). The difference was statistically significant (χ 2 = 14.98, P < 0.0001).

Awareness of voluntary counseling and testing services
All students 309 have heard about HIV voluntary counseling and testing service. There was no statistically significant difference between males and females regarding correct information and Knowledge on benefits of VCT (χ 2 = 0.8, p = 0.4).
Students had multiple responses with regard to source of information about VCT. More than half (58.6%) heard it from mass media (Radio and Television) and others have Source of information about VCT services  There was no statistically significant difference between VCT attendance with regards to gender, age groups, sexual exposure and cadre of the students (Table 4).

Attitude toward VCT
Some questions were asked in order to understand the attitude of students towards VCT services These includes; importance of VCT, reasons for attending VCT, willingness to test and if ARV be should freely available. Almost all students 294(95.1%) agreed that VCT services should be provided free of charge to students. The majority 265(85.8%) agreed that students who are infected with HIV should be freely provided with antiretroviral drugs and only 44(14.2%) were not sure.
Regarding the preferred model of provision of VCT services to students. The majority 275(89.0%) preferred college based VCT, although a large proportion 224(72.5%) reported that the service should be integrated into youth programs such as STIs and family planning. In addition, participants recommended that VCT services should better be given during youth activities like sports, drama and festival. However, the majority 202(65.4%) reported that VCT services for young people should not be mixed with adults and more than a quarter, 107(34.6%) suggested that VCT services should be carried out at private centers in town.

Discussion
In this study we assessed factors related to attitude and uptake of VCT among health care professional students at KCMC in Kilimanjaro region.

Risk assessment
We observed majority of students had sexual debut at an earlier age from six years with mean age of 11 years. These findings are in line with findings from other studies in Africa [7][8][9] and that from America which reported sexual debut to be at 16 and 17 years for males and females respectively [10].
The sexual experience was found to differ between males and females and with different age of sexual debut. Male students were found to be exposed earlier to sex compared to their female counterpart. Similarly older age groups have shown to be more exposed than the youngest group. These differences could be explained by the fact that males were more likely to be explicit about their sexual experiences and that because of early sexual debut older students were found to have more experience than young one as reported else where [7] in Tanga. Female students were found to have multiple sexual partners compared to male students, this could be probably because females are looking for gifts and money so it's possible that females get what they need; they might be tempted to have a number of partners or change of partners. For males, they have to restrict themselves from having many partners, because they have to give something to females. These results are similar with the study report done in Tanga; young females were likely to have multiple sexual partners due to economic reasons [7].
Youths are at risk contracting HIV infections. HIV risk perception is an important determinant of behaviors change and therefore complementing HIV/STI's preventive measures. In this study majority of students do not perceive themselves as being at risk of contracting HIV. The low perceived risk of HIV among youths was also found in other studies [7,[11][12][13]. Compared to other studies where the significant proportion 24% of young people perceived themselves to have had low or no risk [7]. The highest percentage found in this study (62%) compared to that in Tanga (24%) could be due to different study population, Tanga study used youth not at school while in this study we used youth in Health schools. Low perceived risk among youths is reported elsewhere in Africa Kenya, Uganda, South Africa, and Zimbabwe and in USA [13].

Awareness, knowledge and benefit of VCT services
Although in this study the highest proportion among students from different courses was from medical, in general majority of students were aware and knowledgeable about VCT. This finding is in agreement with other studies in Kenya, Uganda and Tanzania [11,14,15] respectively. Mass media played a great role as a source of information on the awareness of VCT in general. Most of students reported to have obtained information from radio and television which are readily available at their homes and within their hostels at KCMC. Majority of students failed to understand several important benefits of VCT services. Benefits such as change of behavior, getting support and early treatment for infected and future planning and risk reduction were mentioned by only few students which is the case to other previously published studies [16,17]. This indicates how the relationship between knowledge and awareness and other behavioural factors is complex, since there is no direct relationship.

VCT uptake and factors associated with
The low uptake of VCT services to majority of the students was a remarkable observation in this study. This study observed slight higher VCT service uptake (34.6%) among students compared to other studies in Uganda (10%) [14] and in Zambia (14.6%) [17]. This might be explained by the poor risk perception and lack of knowledge regarding the VCT benefits.
Religion is important factor reported in several studies regarding the use of condom [11]. Similarly, in this study religion has great influence on the VCT uptake services. Even though the Catholics were the majority for the attendance of VCT, but they have shown the least proportion of attendance to voluntary counseling and testing services as compared to other denominations. This could be explained by the negative attitudes towards condom use and other contraceptive methods offered during VCT services attributed by the religious believe.
Low perception of risk to HIV among youth has been cited in several studies [11,14]. This has also been mentioned as a factor for low VCT uptake in this study.

Attitude and Uptake of VCT services among students
Perceived risk of HIV and benefit of VCT services have a major influence on the attitude and uptake of VCT among youths and other people [18]. In this study majority of students (85.4%) expressed their willingness to test for HIV which correlates with other studies done among youth in Kenya and Uganda [15] and is explained that willingness and practice may not always support each other since many people seems to be willing but those who actually go for the services are few [15]. Reasons to this may be those already mentioned earlier for example lack of youths perceiving their healthy risk in general and lack of perceived benefits of VCT [16,17] but also the important place where the VCT services is being given and who actually gives the service.
Young people are not particularly interested in health issues; they invest their time and interest more in areas like school, job training, sports and media [11]. It was suggested that special efforts have to be done to attract students and other youth in VCT programmes [16]. In this study youths preferred different models of VCT services for young people for example VCT should to be separated from the adults and also VCT services should be carried out in private centers in town by experienced and preferably adults people.
Our findings suggests that health education and health information about HIV and VCT services need to be provided and encouraged to health care professional students, with more emphases on the important and benefits of this services. However, this call for establishment for VCT centers in their respective settings. Findings from this study also urges program managers and practitioners to consider VCT as an important component for care and treatment for HIV/AIDS, VCT services should be provided free of charge and the effort of obtaining drugs should be made so that those who test positive need to access treatment, care and support.

Conclusion
Awareness of VCT services is high among health care profession students at KCM College. However, knowledge on most important benefits of VCT services is still lacking.
Our study has revealed the low perceived risk of HIV among the studied population and this might be one of the contributing factors to their low attendance for VCT services. However, most of the students showed positive attitude towards VCT and reported willing to test if they were given opportunity. Our findings suggest that students prefer a different mode of VCT apart from the existing one.
Youth friendly VCT services need to be established to attract this vulnerable group because they are at risk and mostly affected with HIV/AIDS but the scaring thing is that students themselves do not know about that.
This study have the following limitations: Findings from this study can not be generalized to the whole population of the young people because the study involved only those young people who are in school/colleges and not those who have not attended schools/colleges.
There is a possibility of having under reporting of certain information because the study was done within KCMC premises so students' might fear to disclose some information. Some information needed a recall memory so there could be a recall bias. More research is needed to see on how VCT services could be promoted within this special group of youths.
