Background: Premarital sexual practice among unmarried preparatory, College & university level students have markedly increased recently in Ethiopia. Those students found in adolescent are recognized as most affected by sexually transmitted infections including HIV/AIDS. Sexual activity among unmarried people who do not have access to information about reproductive health and birth control can also increase the rate of unwanted early pregnancy too. A cross sectional study among TVET students was conducted from April-May 2016.Three hundred eighty seven adolescent students were participated. A self-administered questionnaire was provided. The data were cleaned, entered, processed and analyzed using SPSS V.21. The results was summarized in frequencies and percentages and presented in tables, pie chart and graph. The prevalence of premarital sexual practice among the TVET students was 51.9%. Being Male, family monthly income, alcohol consumption, cigarette smoking and chewing chat were factors associated with premarital sexual practice. Premarital sexual practice was more likely to occur among male adolescent students, [AOR=2.638, 95% CI (1.731, 3.950)], alcohol consumption [AOR=3.566, 95%CI (2.650, 4.773), chewing chat, [AOR=2.606, 95%CI (1.526, 4.451)] and cigarette smoking, [AOR=6.451, 95%CI (3.332, 12.501)]. But it was found to be less likely among students whom their family’s monthly income is >4500 ETB, [A0R=0.268, 95% CI (0.137, 0.524)] and 3501-4500 ETB, [AOR 0.274, 95% (0.143, 0.525)]. Hence, this study showed that the prevalence of premarital sex practice among the study participants is higher (52%). Awareness creation should be done among TVET students to avoid unhealthy behaviors like substance use (drinking alcohol), watching videos that push them to start pre-marital sexual practice.

Background

World health organization (WHO) defines adolescent people as those between ages of 10-19years old.¹ Young people undergo a period of development when biological, physical, cognitive, and social traits mature from childhood to adulthood. During this stage, the challenges that youth face and the decisions they make can have a tremendous impact on the quality and length of their lives. Many important life events and health-damaging behaviors that are contributing for pre-marital sexual activities start during theseyears.² According to Ethiopian demographic and health survey (EDHS), 2011, 1.5% of Ethiopian adults age 15-49 are infected with HIV and the number of women age 15-19years who tested positive for HIV is much higher than the number of males in the same age group which is due to early sexual initiation among young females and having multiple sexual partner.³ Premarital sex is penetrative vaginal or sexual intercourse performed between couples before marriage. Some people who advocate virginity and abstinence argue that those people engaged in such sexual practice may have sex with many sexual partners and may have high number of life time sexual partners. As a result, they may be liable to acquire STIs including HIV. Beside, females, particularly adolescent girls may end up with unwanted pregnancy, abortion, teenage deliveries and various complications of these including death. Moreover, the girls may drop out from school to rare their children and in most cases they become economically dependent upon their parents.⁴ The trend in sexual activity of adolescents at younger age increase in the world. In many countries the majority of young people are sexually active before age of 20, premarital sex is common among 15-19years old.⁵ Family consent has been shown to have consistent and strong effects on the timing of sexual debut. Adolescent living in single-parent families or with stepparents initiates sexual activity. Dating, and especially early steady dating, provides a context for many adolescent sexual experience. Previous studies have shown that adolescents' attitudes about sex affect adolescent sexual behavior, more permissive attitudes lead to earlier first sex.⁶

Statement of the problem

One in every five people in the world is an adolescent, defined by World Health Organization as a person between 10 to 19years of age. Unsafe sex is a major threat to the health and survival of millions of adolescents. Each year, one in 20 adolescents worldwide contracts STI including HIV/AIDS. Every day, over 7000 young people aged from 10 to 24years become infected with HIV/AIDS. Globally more than half of all new HIV infections are among 15 to 24years old.^7,8 Early sexual initiation may predispose young people to HIV/AIDS as their chances of having several partners before marriage increases.⁹ Therefore, delaying the age of sexual debut and increased condom use is recommended in preventing HIV infection for this age group.¹⁰ In many societies, premarital sex is a taboo, especially among unmarried girls.¹¹ This norm is widespread in rural Ethiopia, as in many traditional societies too.¹² A study about the concepts of HIV and AIDS in Ethiopia suggested that premarital sex may contribute to the expansion of HIV and AIDS. Indeed, several studies from Ethiopia have shown that young people are engaged in premarital sex with multiple sexual partners, and do not use condoms at all or use them irregularly.¹³ Adolescents in Ethiopia are also exposed to various risks such as unprotected sex, early marriage, early pregnancy, sexually transmitted infections (STIs) and HIV/AIDS, unemployment, drug abuse and crime.¹⁴ According to the study conducted in Ethiopia, 66.2% of the adolescents expressed that they had sexual intercourse and of those who had ever had sex, the age at first intercourse ranged from 8 to 31years with the mean age of 17.4 and females had their first intercourse at significantly younger age. In addition, out of the total respondents, 53.8% have regular partner while the remaining 46.2% reported no regular partners.¹⁵ In order to tackle these problems, adolescents should learn to develop the life skill they need to survive in their environment. Life skill based education enables them to develop ability in critical thinking, problem solving, self-management and interpersonal Communication skills in order to adopt a healthy behavior. Because, when sexuality is discussed openly and when young people learn more about their bodies and their emotions, they are better able to cope with sexual maturation.¹⁶ Educational institutions like TVETs and Schools are the ideal places where adequate and accurate information be provided along with their formal education. Moreover, peer groups in school play a great role in information dissemination and help students internalize the facts that lead to behavioral change. Actually this needs an integrated effort of adolescents, school- teachers, the family and other relevant bodies.¹⁷ In general, many literatures suggest that the individual, family and peer variables have considerable influence on the sexual behavior of the youth. However, it is one of health related problem affecting large segment of youth in Ethiopia, due to the sensitivity of the topic of premarital sexuality; youth receive inadequate education, guidance and services on reproductive health. To fill the gap, it is thus imperative to study the prevalence of premarital sex and the factors surrounding premarital sex in the context of TVET students in order to inform Ministry of Health (MOH), Ministry of Education and planners to develop appropriate and timely intervention programs to prevent high risk sexual behavior such as premarital sex and unsafe sexual practices in this segment of populations.

Significance of the study

The study revealed that the prevalence of premarital sex and unprotected sexual practice among TVET students is the critical issue to be studied. Because the students of these age groups are facing struggles on their activities because of immaturity, acquired new developmental stage and hotness. Hence, these students do not get adequate reproductive health services and may be practicing unsafe sex and exposed to HIV infection and other STIs. The result of this study is important to provide baseline information related to TVET students sexual behavior in the area and the baseline data will be used by different stakeholders like Ministry of Health, Ministry of Education and other Organizations to take appropriate measures to improve current sexual behavior of the students in order to prevent burdens following premarital sex and unprotected sexual activity such as sexually transmitted infections and unwanted pregnancy.

General objective

To assess the prevalence of premarital sexual practice and associated factors among students in Robe TVET College in Robe town, Bale Zone, South East Ethiopia, may 2016.

Specific objectives

1. To assess the magnitude of pre-marital sexual practice among students in Robe TVET College in Robe town.
2. To identify factors associated with premarital sexual practice among students in Robe TVET College, in Robe town.

Study area and period

The study was conducted in Robe Town which is located in Bale Zone, one of the Oromia Zones and which is 430 km away from Addis Ababa, the capital city of Ethiopia. Robe town is surrounded by Sinja farmers association in South, Hawusho farmers association in South West, Horaboka farmers association in West, Sanbitu peasant association in North and Shallo farmers association in East. The total land coverage of the town is 80,240,000 meter square.

The number of students training in the college were 880 of which 434 male and 442 female students.

Study design and period

A cross-sectional study design from April to May, 2016.

Population

Source population

All students attending their regular education program at the time of data collection at Robe TVET College.

Study population

All sampled students at the time of data collection.

Inclusion criteria

All regular, unmarried students whose age greater than 15 years old.

Exclusion criteria

Students who are critically ill or absent at the time of data collection were excluded from the study.

Sample size determinations and sampling technique

Sample size determination

The required sample size was calculated by using the following formula and p-value obtained from study conducted in Goba, prevalence of premarital sexual activities and associated factors among undergraduate health science students, Madda Walabu University (47%.) ,Goba town.

A single population proportion formula of

$$n={\left(\frac{Z\alpha }{2}\right)}^{2}p\frac{\left(1-p\right)}{d^2}$$

P = 0.47 (prevalence of premarital sexual activities)

95% confidence interval

Margin of error 5% (d = 0.05)

Computing with the above formula and 10% of contingency for non-response rate gives a total sample size of 422.

$$n=\frac{{\left(1.96\right)}_{{}^{{}^2}\times 0.47\left(1-0.47\right)}}{{0.05}^2}=383$$

383×10/100=39(non-response)

383 plus 39= 422                                                         

Sampling Procedure

Robe TVET classes and respective numbers of students in the classes were identified and selected by using proportional allocation to sample size and simple random sampling technique was used to select study participants from each class (Figure 1).

Figure 1 Schematic presentation of sampling procedure.

Study Variables                

Independent variables

Socio-demographic variables (age, sex, level, family size, parents’ educational status and family monthly income).

Substance use (alcohol, Khat), cigarette smoking

Dependent variables

Premarital sexual practice

Sample size determination and sampling procedure

An institutional based cross sectional quantitative study design was used. The sample size for the quantitative study was determined using a single population proportion formula with the following assumption: Prevalence of pre-marital sex 47%,²⁴ margin of sampling error tolerated - 5% (0.05), critical value at 95% confidence interval of certainty (1.96), 10% for non-response making the final sample size of 422.Quantitative data were cleaned ,edited &entered in to epi info 3.2.1 and exported to the statistical packages for social science (SPSS) version 21 were used for further analysis .frequency distribution and cross tabulation were done against the variables of interest. Bivariate analysis was done to the association between explanatory variables and outcome variables of the study. Variables significant at p-value of 0.2 in bivariate analysis included in multi variable logistic regression model in which odds ratio with 95% confidence interval were estimated to identify independent predictors of premarital sexual practice. The structured questionnaire was adopted from literatures of similar study &prepared by English language and translated to local language by an expertise of both languages and also retranslated back to English to check its consistency. Pilot study was conducted on 5% of sample size Battu Terera TVET college of Goba town. Three trained data collectors of elementary school teachers and two supervisors were recruited. The data were collected by using self-administered questionnaire and then checked by supervisors on the field. Data were cleaned, coded and entered in to computer were done by data clerk. The supervisors checked each completed questionnaire and principal investigator monitored the overall quality of the data collection.

Operational definitions

1. Age of sexual debut: The age at which the first sexual intercourse occurred.
2. Monthly income: A total amount of money that earned monthly by somebody or by family members directly or indirectly.
3. Premarital sex: A penetrative vaginal sexual intercourse performed before formal marriage.
4. Substance abuse: pattern abuse of drug in which user consume the substance in amount or with methods which are harmful to themselves or others
5. Unprotected Sexual Activities: Sexual activities performed without protection from pregnancy and other STIs (without proper utilization of condom).

Data management

Data were analyzed by using SPSS Version 21.During the process of analyzing, frequency distributions, pie chart, figures and tables was used to present the data. Odd ratio was calculated on to determine the strength of association among variables.

Ethical consideration

 Ethical clearance was obtained from the Ethical Committee of Madda Walabu University, Goba referral hospital. Letters of permission was obtained from Bale Zone Health Bureau and Goba Town Health Office. Informed consent was obtained from participants involved in the study. The participants were allowed to consider their participation and given the opportunity to withdraw from the study at any point in the course of the study if they wished to do so. Participants’ name or personal identifier was not included in the written questionnaires to ensure participants’ confidentiality.

Dissemination of results         

Findings of the study will be communicated to the College where the study was conducted, to Ethiopian Ministry of Education to inform the importance of reproductive health for school adolescent, School of Health Science through soft and hard copy after presentation. The findings will also be disseminated to different organizations those have a contribution to promote health and prevent diseases related to adolescent reproductive health in the region and zone.

Figure 4 Status of first sex of Robe TVET Students, in June 2016.

Sexual education

 Majority of the study participants, 364(94.1%) accept that sex education was necessary and the rest 23(5.9%) did not. Majority of the study participants, 193(49.9%), were obtaining information of health education from Media and school, 154(39.8%) and the rest from home, 97(25.1%), peers, 90(23.3%) and others from institutions, 114(29.5%) (Table 6).

Substance use

Out of 387 study participants, majority of them (73.1%), never drink alcohol (20.9%), and drunk occasionally (2-3times/ month), (3.6%), drunk 2-3 times per week and the rest, (2.3%) drunk daily. From which most of them, 70(67.3%) were encouraged by their friends, 17(26.3%), start alcohol drinking by themselves, and the rest, 9(8.7%), 6(5.8%) and 2(1.9%), were encouraged alcohol drinking by their siblings, parents and the person whom they did not know respectively around the time they had unprotected sexual practice. The respondent’s family, 115(29.7%), were drinking alcohol, 263(68.8%) were not and the rest, 9(2.3%), respondents did not know who drink alcohol in their family. Majority of the respondents (89.0%) were not smoking and (10 %) of them were smoking cigarette. Out of 39, majority of them (56.4%) were encouraged by their friends which predispose them to had unprotected sexual practice. Regarding the prevalence of respondents' family smoking history ,(19.6%) of them were smoking, of which, 39(51.1%) were fathers, 15(19.9%) siblings, 7(9.2%) mothers and the rest, 6(7.9%). Concerning chat chewing, 251(64.9%) were not chewing, and 136(35.1%) of them were chewing chat, from which majority of them, 70(51.1%) were influenced by peers pressure and the rests, 25(18.4%), 20(14.7%), 11(8.1%), were encouraged chewing chat by their fathers, did not remember and by strangers respectively which subsequently cause them to practice unprotected sexual intercourse. When we see respondent’s family behavior of chewing chat 144(37.2%), were chewing chat and 243(62.8%), of them were not chewing, from which majority of them, 39 (51.3%) were fathers (Table 7).

Factors associated with premarital sexual practice

The Logistic regression analysis showed that premarital sexual practice was more likely among Male TVET Students, [AOR=2.638, 95%CI (1.731, 3.950)], drinking Alcohol, [AOR=3.566, 95%CI (2.650, 4.773), chewing chat, [AOR=2.606, 95%CI (1.526, 4.451)] and smoking cigarette, [AOR=6.451, 95%CI (3.332, 12.501)]. But it was found to be less likely among students whom their family’s monthly income is >4500 ETB, [A0R=0.268, 95%CI (0.137, 0.524)] and 3501-4500 ETB, [AOR 0.274, 95% (0.143, 0.525)](Table 8).

The prevalence of premarital sexual practice among study participant was 51.9% with mean age of 17.7years and maximum age 21 and minimum ages 14. When compared to study conducted at Nekemte, premarital sex was 21.4%¹⁹ and Agaro High school, 25%.²⁰ The premarital sexual practice is higher when compared to these studies because participants of this study are affected by peer pressure and living separated from their parents where family fear and control is not available.^19,21,22 Being adolescent and early adulthood is characterized by different types of risky behaviors, including risky sexual practice, substance abuse and exposure to STIs.²³ Adolescents and college students premarital sex is increasing around the world many of which are risky, unplanned and unprotected.^18,24,25 The mean age of first sexual intercourse of the study participants at which 17.7years which is higher than the study conducted at Addis Ababa was 12years for boys and 14years for girls.²⁶ This is may be due to many of the study participants are from rural area living in the town for education. The main reason of having sexual intercourse of study subjects is personal desire, 118(58.7%) followed by peer pressure, 49(24.4), substance use, 23(11.4%). But the reason of having premarital sex among Addis Ababa high school students was peer pressure (35.2%) rape and use of drugs which is comparable to the current study (38). Out of study participants who experience premarital sex 90(44.8%) had only one sexual partners whereas 68(33.8%) had two sexual partners and the remaining, 43(21.4%) of them had more than two sexual partners. Similarly the study conducted among Agaro High school students showed that 55.6% had one sexual partner.¹⁹ Using condom during sexual intercourses is one of the preventive methods of STIs including HIV/AIDS and unwanted pregnancy. 52.7% of study participants were used condom during first sexual intercourse and 67.25 were used condom during their most recent sexual intercourse. When compared to the study conducted in different parts of Ethiopia, among secondary school students, in North West Ethiopia, 45.9% were used condom²⁷ and among Agaro High school students, 54.4% were used condom during their sexual practice.¹⁹ The study subjects of this study area were highly utilized condom during their sexual practice the reason behind may be due to level of education and better access to reproductive health. Out of total respondents 26.8% drinking alcohol, 10.0% of them smoking cigarette and 35.1% were chewing chat. Study conducted to other part of Ethiopia, West Shoa, showed that, 16.7% of respondents reported to chewing chat and 66.7% of them were consuming alcohol. When we compare alcohol consumption, it is lower than in this study, this may because of low income and religion implications.^28‒36 But smoking cigarette and chewing chat are comparable. Sex and respondent’s family’s monthly income were among socio demographic variables associated with premarital sexual practice. Male students are 2.638 at risk to experience premarital sexual practice compared to female students. But it was found to be less likely among students whom their family’s monthly income is >4500 ETB and 3501-4500 ETB compared to whom respondents monthly family income is <1500. This may be because of respondents whom family incomes is less is more likely to be involved in premarital sexual practice for economic problem than whom family’s monthly income is more. It was found that respondents who drink alcohol were 3.56(2.65, 4.77) at risk to practice premarital sex than who never drink alcohol, who chew the chat were 2.60(1.52, 4.45) at risk to practice premarital sex than who did not chew and who smoke cigarette were 6.45(3.33, 12.50) at risk to practice premarital sex.^37‒46 When we compare with study conducted at West Shoa Zone, Oromia regional state, students who drink alcohol were 2.6times more likely to be involved in premarital sexual practice when compared to students who did not drink alcohol.

The study revealed that the prevalence of premarital sex among the study participants is higher. Male sex, respondents’ family monthly income, alcohol consumption, smoking cigarette and chewing chat are factors associated with premarital sexual practice. Colleges should work with health institutions to set reproductive health and to reduce premarital sexual practice and its risk.

Zonal health department and educational offices at different level should work together in order of promoting open discussion about sexual related issues and provide adequate and updated reproductive related information through school health education, by establishing reproductive health club in the college. Awareness creation should be done among TVET students to avoid unhealthy behaviors like substance use (drinking alcohol), watching videos that push them to start pre-marital sexual practice. Finally Robe town administration should design persistent and effective health education to decrease pre-marital sexual debut in unmarried adolescent students.

Our special gratitude and appreciation goes to Madda Walabu University, Goba referral hospital, Department of Public Health for giving us the opportunity to conduct research from which we learn many things.
