Sexual risk behaviours of high school female learners in Mbonge subdivision of rural Cameroon

Introduction Since female learners in high schools in Cameroon fall within the age group hardest hit by HIV/AIDS, it is assumed that these learners might be exposed to sexual risk behaviours. However, little has been explored on the sexual risk behaviours of high school female learners in Cameroon. This study aimed at examining the sexual risk behaviours of high school female learners in Mbonge subdivision of rural Cameroon. Methods A cross sectional design was adopted, using a self-administered questionnaire for data collection. Respondents were selected through disproportional stratified simple random sampling resulting in 210 female grade 10 to grade 12 learners from three participating high schools in Mbonge subdivision, Cameroon. Descriptive and inferential statistics were calculated using SPSS version 20 software program. Results Majority of the respondents, 54.0% reported being sexually active, of whom only 39.8% used condoms during first sex; 49.5% used condoms during last sex and 29.6% used condoms consistently. Up to 32% of the sexually active respondents had multiple sexual partners in the past one year before the study, while 9.3% had multiple sexual partners during the study period. The mean age of first sex was 15.6 years. Lack of parental control, religion, academic profile, poverty, place of residence and perception of risk of HIV infection were the main factors significantly associated with sexual risk behaviours. Conclusion The findings indicate that sexual risk behaviours exist among high school female learners in Mbonge, Cameroon. There is need for campaigns and interventions to bring about sexual behaviour change.


Introduction
HIV/AIDS remains a global challenge. Of the 34 million people living with HIV/AIDS worldwide in 2010, almost 68% reside in sub-Saharan Africa (SSA), a region with only 12% of the world's population [1]. Young people are the most threatened globally. In SSA, young people aged 15-24 accounted for half of all new HIV infections in 2009 [1,2]. Therefore monitoring the sexual behaviours of this vulnerable age group is necessary in order to control the HIV/AIDS pandemic. Sexual risk behaviours include engaging in unprotected vaginal intercourse, early sexual debut, multiple sexual partners and coerced or forced sex [3][4][5]. These risky sexual practices are influenced by many factors including the lack of accurate information on the modes of transmission of HIV/AIDS, economic conditions, gender inequalities, living place, religion, perception of risk of HIV infection, age and academic profile [6][7][8][9][10][11].
Young people are particularly vulnerable to HIV infection because of risky sexual behaviours and substance abuse. These behaviours are convoluted by lack of access to accurate and personalised HIV information and prevention services and many other socio-economic reasons, living away from parents and free from parental control, peer pressure and lack of youth friendly recreational facilities [12].
Despite a wealth of research on youth, little research has been done on the sexual risk behaviours of high school learners in Cameroon.
Thus this study aims to examine the sexual risk behaviours of high school female learners in Mbonge rural area of Cameroon, for possible interventions.

Methods
The design used to examine the sexual risk behaviours of high school female learners in Mbonge rural area of Cameroon, was descriptive and correlational, collecting data through selfadministered questionnaires. The questionnaire was pretested to clarify instructions, relevancy, usability and completion time, to refine and introduce modifications where necessary and to ascertain reliability and validity [13]. During the pre-test, 10 students, who did not participate in the actual study, completed the questionnaires. They required no assistance, understood the questions and needed approximately 30 minutes to complete the questionnaires. The reliability of the research instrument used for the study was tested by pre-testing the questionnaires. The following types of validity were also established: face validity, content validity, construct validity and criterion-related validity. This was ensured by constructing items to represent the different components of the study, based on literature review. The questionnaires were distributed 210 female learners in three high schools in Mbonge rural area of Cameroon during normal class periods with the permission of the principals and the co-operation of the teachers concerned. One research assistant was available to assist the learners and to answer questions while they completed the questionnaires during a classroom period. To obtain the sample, the researcher used the school attendance registers of the learners as a sampling frame. Data collection took place during the first term Participation was voluntary and informed written consent was obtained from each learner and her parent/guardian prior to data collection. A questionnaire was handed to a learner when she produced the signed consent form from a parent/guardian and from herself. Anonymously completed questionnaires were kept in a separate container from the signed informed consent forms in order to maintain anonymity. Anonymity was also maintained by reporting the findings of the three schools combined and by not providing comparisons among the three schools. Confidentiality was maintained because only the researcher had access to the completed questionnaires, which were locked up. Subsequent to the acceptance of the research report, these would be destroyed. Data were collected in three sections: socio demographic variables, knowledge of prevention of HIV/AIDS and knowledge of sexual risk behaviours, and sexual behaviours.

Results
The socio-demographic characteristics of the respondents are shown in Table 1 (76.2%) believed that having multiple sexual partners is a sexual risk behaviour. Majority of the learners, 119 (66.5%) also believed that coerced or forced sex is a sexual risk behaviour.
Regarding the perception of risk of HIV infection, less than half of the learners, 80 (39.4%) indicated that they were at high risk of HIV infection. Table 3 explicates the sexual behaviours of the learners. The majority, 108 (54.0%) reported having experienced sex. Learners who lived in rented places, 36 (66.7%) were more likely to have ever had sex than those who lived in their parents' or guardians' houses, 59 (43.1%) (p=0.034), while learners with low academic profiles, 41 (74.5%) were more likely to have experienced sex than those with high profiles, 58 (40.6%) (p=0.000). The mean age (SD) at first sex was 15.6 years (3.1). By age 16 years, the majority, 58 (59.2%) had already experienced sex. Among learners who ever had sexual intercourse, 23 (20.4%) were forced into sex during their first sexual encounters, while 17 (15.0%) were influenced by their friends. Learners who lived in rented places, 19 (41.3%) were more likely to have experienced sexual coercion than those who lived in their parents' or guardians' houses, 32 (40.5%) (p=0.007). Learners with high academic profiles, 18 (26.9%), were more likely to have been forced by their partners during first sex, than those with low profiles, 4 (9.8%) (p=0.000). Learners who perceived themselves at high risk of contracting HIV/AIDS, 28 (47.5%), were more likely to have been forced by their partners into first sex than those who perceived themselves not at risk, 12 (26.1%) (p=0.016). Learners resident in the suburbs and rural settings, 7 (24.1%) were more likely to have been forced by their partners into first sex than those resident in the townships and cities, 17 (21.8%) (p=0.040). Christians, 22 (20.8%) were more likely to have been forced into first sex than Muslims, 0 (0.0%); while among the Christians, non-Pentecostals, 21

Discussion
Majority of the respondents were aware of the measures to prevent HIV/AIDS: correct and consistent condom use (72.5%), abstaining from sex (91.6%) and being faithful to one sexual partner (83.1%).
These percentages are higher than those obtained by Rwenge in Bamenda in 2000 [14], and also higher than those obtained in Rwanda [15]. Knowledge of sexual risk behaviours was also high: early sexual debut (70.9%), unprotected sex (79.5%), multiple sexual partners (76.2%) and coerced sex (66.5%). However, less than half (39.4%) of the respondents felt they were at high risk of HIV infection. This percentage is higher than those in Tiko, Cameroon (18.8%) [16] and in Rwanda (3.2%) [15]. This disparity might be because of the interventions that have been given at different levels in Cameroon. Nearly all (93.3%) the respondents were unmarried, thus restricting the study to single young females.
One hundred and eight (54.0%) respondents reported ever having had sex. This is similar to that obtained in Tiko, Cameroon (47.3%) [16], but higher than those obtained in Rwanda (33.0%) [15] and in Ethiopia (28%) [17]. This disparity could be due to the cultural differences in relation to sexual activity between these two countries and Cameroon.
The study showed that sexual risk behaviours is common among the respondents. The respondents reported a very young age of sexual debut (15.6 years). This is similar to those obtained in Bamenda, Cameroon (15.8%) [18], in Tiko, Cameroon (16.9%) [16], in Rwanda (15 years) [15] and in Ethiopia (17.5%) [17]. The early age of sexual debut might indicate that the issue of early sexual initiation is a common problem in Africa. Twenty three (20.4%) respondents said their first sex was forced, which is less than that obtained in Bamenda (30.0%) [14], but similar to that obtained in Ethiopia (12.2%) [17]. The decrease in incidence of forced sex in Cameroon might be due to the behavioural interventions that have taken place at different levels. Among the respondents who had experienced sex, 32.0% had multiple sexual partners in the one year before the study period, which is similar to that obtained in Tiko, Cameroon (42.8%), [16], Rwanda (33.0%) [15] and Ethiopia (33.5%) [17]; while 9.3% had multiple sexual partners at the time of the study which is lower than results obtained in Bamenda Cameroon (27.0%) [18] and Ethiopia (24.5%) [17]. This indicates that despite interventions, the behaviour of learners regarding multiple sexual partners remains high in Africa.
The overall prevalence of ever use condoms among the sexually active respondents was 75.3%, which is similar to that obtained in Ethiopia (64.1%) [17]. Only 39.8% of the sexually active respondents used condoms at first sex, which is higher than results obtained in Rwanda (8.3%) [15]. This disparity might be due to cultural background differences between Cameroon and Rwanda.
Fifty two (49.5%) sexually active respondents used condoms during the last sexual intercourse, which is higher than results obtained by Rwenge in Bamenda (25%) [18] and that obtained in Rwanda (13.2%) [15]. This might be due to the behavioural interventions that have taken place at different levels in Cameroon. The disparity between Cameroon and Rwanda could be due to cultural background differences between the two countries. However, consistent condom use as reported by the sexually active respondents was low (29.6%), but higher than that obtained in Ethiopia (20.4%) [17]. This could also be due to cultural Poor female learners may be pushed into sexual risk behaviours to ensure survival, receive material goods to relieve poverty; and this behaviour is likely to be associated with increased HIV risk. Low socio-economic status appears to be associated with learners having experienced coerced sex [9]. Living alone, away from parents is an important factor associated with adolescents' behaviours. Youth who live with both parents appear to be less likely to engage in sexual risk behaviours than those living alone. Living in a family with either parents or guardians present implies the availability of support, supervision and behavioural control in the lives of adolescents [19].
Learners living in the cities and townships have easy access to formalised information regarding HIV/AIDS and preventive measures than their counterparts living in the suburbs and rural settings. This gives them the opportunity to engage in safe sexual practices. Concerning religion, it is significant that a high religiosity made adolescents less likely to engage in premarital sex; teenagers, who attended religious services regularly, delayed the timing of their first sexual encounters; adolescents who are highly religious are less likely to use condoms during sexual intercourse [20][21][22]. A high level of academic engagement has an influence on the age of sexual initiation and makes health education messages more meaningful [23,24]. Adolescents with high academic aspirations are more likely not to jeopardise their academic careers by unwanted pregnancies and STDs, including HIV/AIDS, by abstaining from sex, by being faithful to one sexual partner, or by using condoms when engaging in sexual intercourse with multiple partners.
