Knowledge, attitude and practice towards risky sexual behaviors among secondary and preparatory students of Metu town, south western Ethiopia.

BACKGROUND: Sexual risk behaviors are defined as sexual activities that may make an individual liable to the risk of sexually transmitted infections including Human Immunodeficiency virus (HIV) and unplanned pregnancies. Adolescents are at high risk of developing sexual risk behavior. The rate of risky sexual behaviors and the spread of STIs continue to be increase among the adolescent population. Therefore this study aimed to assess Metu secondary and preparatory school adolescent knowledge, attitude, and practice of risky sexual behaviors.
METHODS: Institution based descriptive cross sectional study was conducted among Metu secondary and preparatory school students from 04 Feb 2019-07 June 2019. The study participants were selected through systematic random sampling techniques and the data was collected through self-administered questionnaires. A Total of 361 study subjects were included in the study. Data was entered in EpiData and analyzed by using SPSS version 21.
RESULTS: Three hundred sixty one respondents participated in this study. Of those, 75.9% of them have awareness about risky sexual behaviors and about 76.5. % of them has awareness on consequences of unsafe sex. Among the total study participants, about 22.7% of them had previously practiced in sexual activity; of these 61.7% of respondents had more than one sexual partner. From the respondents who had practiced sex, 19.8% of them had always used condom during their sexual intercourse with their partners, while 58% of them never used condom during sexual intercourse.
CONCLUSIONS: Even though the majority of the students have an awareness regarding sexual risk behaviors, a considerable number of students have practiced risky sexual behaviors that might predispose them for different sexual and reproductive health problems and peer pressure was revealed as a major factor that influences the respondents towards their first sexual intercourse. Peers have greater influence on the positive and negative behavior of their friends. Therefore the school should emphasize on promoting peer educators and peer discussion to protect adolescents and youth from risky sexual behaviors.

Background

Different organizations and scholars define adolescents in different ways. The World Health Organization (WHO) defines adolescence as any person between ages 10 and 19 years. It’s a transitional stage of growth and development during which young people experience changes following puberty [1]. Since during this phase people become sexually active, healthy sexual awareness is mandatory for the future health status of the adolescents [2, 3]. Adolescents will develop different risky sexual behaviors, if they are unaware of healthy sexual behavior [3-5]. Some of risky sexual behaviors are having multiple sexual partners, sexual intercourse with commercial sex workers, unprotected sexual intercourse, coerced sexual intercourse and sexual intercourse for reward [6].

According to different studies, sexual risk behavior affects adolescents and youth life style and also contributes to different adverse effects, but its prevalence is rising due to many factors including lack of information regarding adolescent sexuality. Based on the UNAIDs report in 2013; globally there were 35 million people living with HIV, among which, youth between the ages of 15–24 years accounted for approximately 33% of new HIV infections. The WHO report showed that 333 million new cases of STIs occur globally each year, and at least 111 million of these cases occur under 25 years old peoples [6-8].

Studies revealed that sub Saharan countries including Ethiopia are the most affected. According to the family planning guidance association of Ethiopia, about 72% of boys and 71% of girls have had their first sexual contact within the age range of 15–17 yrs. while 13% of them started sexual activity between 10 and 14 yrs. of age. Analysis of 2002 in the country showed that 54% of pregnancy to girls under age 15 is unwanted as compared to 37% for those ages 20–24. According to these studies, major predisposing factors for raise of sexual activity among adolescents are increased pre-marital sex, deterioration of traditional norms & values that discourage premarital sex & media that transmit new ideas via movies. This indicates that the need to refocus programs and prioritize interventions tailored to adolescents under the age of 15 years [5, 9, 10].

As the study conducted in USA; the magnitude of risky sexual behavior was 46%, while in Ethiopia risky sexual behavior among secondary and preparatory school students was progressively increasing, for instance it was reported to be 15% in Jiga and 33% in Jimma [11-14]. A study conducted in Gonder city showed that, 20% of sexually active respondents ever had more than one sexual partner concurrently. Furthermore 16.7% of all sexually active male respondents had sexual contact with commercial sex workers, among those 81.2% of them never used condom. In Shendi town, north Ethiopia showed that, 19% of the study participants have had premarital sexual intercourse at the time of the survey, from which 7.6% had sexual experience with commercial sex workers. Another study conducted in Boditti, South Ethiopia showed that, about 21% of the respondents who sexual intercourse had it with two and more sexual partners in their lifetime [15-17].

Many investigations have been conducted on risk sexual behavior in different population groups, however it was neglected among young secondary school students in the study area. Despite different stakeholders’ effort to create awareness and to reduce STI, the rate of contracting STIs including HIV/AIDS is at an increasing rate [18]. Therefore, this research aimed to assess the school adolescent’s knowledge, attitude and practice of risky sexual behavior. The study will provide pertinent data on knowledge, attitude and practice of adolescents’ risky sexual behavior and it will give directions to tackle the problem of risky sexual behaviors in adolescents. Moreover, this research will provide better information for the governmental and NGO working on adolescents to improve their health both nationally and internationally. The study will also be a baseline by providing information for other researchers who want to conduct further surveys on this area and contribute to the development of the nation.

Methods

Study area and study period

The study was conducted in Metu secondary and preparatory school in Metu town, Oromia region, south western Ethiopia. Metu town is located 606KM away from Addis Ababa and 265Km from Jimma town. The town possesses three kebeles (which is the smallest administrative unit in Ethiopia); namely: 01, 02 and 03 and has an estimated total population of 46,810, from whom 23,786 are male and 23,024 are females. The main source of incomes of the indigenous community is agriculture. Metu is also known for honey and coffee production. The town has three secondary schools and two preparatory schools. This study was conducted among Metu secondary and preparatory school adolescents. The study was conducted from 04Feb-07June/2019.

Study design

Institution based cross- sectional study was conducted.

Source of population

All secondary and preparatory school adolescents in Metu town who were attending their class in 2019.

Study population

All Metu secondary and preparatory school adolescents attending the class during the school hour.

Inclusion criteria and exclusion criteria

Inclusion criteria

All students who have been present during the time of data collection at Metu Secondary and Preparatory School.

Exclusion criteria

Those who were seriously ill to the extent of unable to respond during the data collection period.

Sample size determination

A single population proportion formula was used to estimate the sample size. The following assumptions were made while calculating the sample size. The degree of precision or margin of error chosen to be 0.05 with the reliability coefficient of 1.96% certainty (Z = 1.96). The prevalence rate of Risky Sexual Behaviors among Adolescents of Jimma University Community High School was 54.6% (21). The final sample size for this study with 10% non-response rate was a total of 362 students and systematic random sampling technique was used.

Sampling procedure

A total of 2388 students are found in Metu secondary and preparatory school. A sampling frame which contained the lists of all students under each grade level (9th, 10th, 11th and 12th) was developed based on the lists obtained from students’ record office. Then the total sample size (362) is proportionally allocated for each grade levels as follows (Fig. 1) and after calculating ‘K’ value, a systematic random sampling method was used to select the participants.

Data collection tools and method

Data was collected by using structured, pretested and self-administered questionnaires from March 15–16 / 2019, which is adapted and modified from different reviewed literature (15–16, 18). The question and statements were arranged according to particular objectives that they could address.

After revision, the questionnaires which were prepared in English were translated to local language (Afan Oromo) and again then backed to English to ensure the similarity of its message. Pretest was conducted with 5% of sample size at Abdii borii secondary and preparatory school students before the actual data collection was conducted. After checking of questionnaires completeness with a pretest, the questionnaires are handed out to the students who consented to participate in the study and after securing informed consent, the actual data collection was conducted by using self-administered structured questionnaires. Fourth year Nursing Students collected the data and were principal investigators responsible to lead the data collection process.

Operational definitions and definitions of terms

Knowledge

Questions were delivered to study participants in “Yes” or “No” options, and each correct response was given a score of 1 and a wrong answer given a score of 0. The total knowledge score ranged from 0 to 16. We computed the mean score to determine the overall knowledge of sexual risk behaviors of respondents. Those who scored the mean score and above are considered as having a good knowledge, whereas those respondents who scored below the mean score were categorized as poor in knowledge of risky sexual behavior.

Attitude

We assessed the attitude using a 2 point Likert scale. In the scoring system that was used: Disagree =0 and Agree = 1. The total attitude score ranged from 0 to 8. Then we calculated the mean score. Those who scored the mean score and above are considered as having a positive attitude, whereas those who scored below the mean score were categorized as negative in attitudes towards risky sexual behavior.

Risky sexual practice

Those respondents who had sex before 18 years, used condom inconsistently and had multiple sexual partners.

Data processing and analysis

Data was cleaned, coded and then entered into the computer using EpiData and exported into SPSS 21th version for analysis. The finding was presented by statements, graphs and tables.

Discussion

Many studies have been conducted on risk sexual behavior in different population groups in different parts of the world including Ethiopia, however the issue was neglected among young secondary school students in the study area. Therefore this study aimed to assess knowledge, attitude and practice towards risky sexual behavior among adolescents.

The study has found that 76.5% of respondents have awareness about the consequences of risky sexual behaviors. This finding is lower than a study conducted in Jimma; at which about 85% of the respondents knew consequences of risky sexual behavior [14] and higher than a study conducted in Nepal 67% [19]. This difference might be due to information source gaps, difference in educational background of the respondent’s parents and socio demographic difference.

The result of this study revealed that about 43% of respondent’s source of information about sexual matters were the parents. It is high as compared to a study done in Nigeria 11% [20] and Zambia 7% [21]. This dissimilarity might be due to lack of open communication between parents and adolescents about sexual matters.

According to the result of this study about 38% had good knowledge about risky sexual behaviors. This is lower than finding of a study in Jimma 77% [14], Bophuthatswana 70% [23]. This difference might be due to the difference on cut point, the nature of questions that respondents were asked, and study populations from different cultural and socio demographic backgrounds.

From the total study respondents, about 52% of them have a positive attitude towards risky sexual behavior which is in line with the study conducted at Jimma; in which 55% of them had a positive attitude towards risky sexual behavior [14]. This disparity might be due to not having communication about sexual matter with their parents, as result most information for their scattered knowledge comes from peers of the same sex who themselves lacks adequate information about reproductive health [23].

Based on the findings of this study, 23% of the respondents had ever practiced sexual intercourse which is lower in comparison with a study done in USA 46% [11, 12], Jimma 33% [14], Boditti, south Ethiopia 29% [17], higher than a study done in Nepal 9% [19] and was in line with a study done in Kenya, Nairobi 22% [24]. This difference might be due to difference in study participant Socio demographic, difference in traditional and cultural background.

According to the findings of this study, peer pressure (22%) was the major reason/ factor that influenced the respondents for their first sexual intercourse. This finding is lower than a study done at Boditi, South Ethiopia 40% [17] and Nepal 34% [19]. This disparity might be due to dissimilarity in interest and satisfaction of the study subjects, and level of peer influence on sexual matters.

In this study, from a total of 81 respondents who had ever sex, 62% of them had multiple sexual partners which is higher as compared to a study conducted in USA 41%, Jiga 29%, Gonder city 20%, Shendi town, west Gojam 25%, boditi, South Ethiopia 21% and Nigeria 7% [11–13, 15–17, 20]. This dissimilarity may be due to the difference in community norm about multiple sexual partners.

Among the study participants who had committed sex (81), about 42% of them used condom when they had their last sex. This finding is lower than a study conducted at Nairobi, Kenya (89%) [24], Gonder city 67.6% [15], USA 61% [11, 12], higher than Nigeria 27% [20] and Jiga 17% [13]. This difference might be due to lack of trust or faithfulness, decreased pleasure, lack of knowledge of condom benefits, less fear of contracting HIV/AIDS as it can now be controlled by medication, influence of tradition and scarcity of female condoms and the perception by women that it is complicated to insert.

Since the study was on a very sensitive and private issue; the possibility of underestimation cannot be ruled out and the study is limited to school so that the result cannot be generalized to the whole adolescents in the study area and due to the nature of the study design may not show cause and effect so that it should be repeated with different study design.

Conclusions

Even though the majority of the students have an awareness regarding sexual risk behaviors; considerable number of students have practiced risky sexual behaviors that might predispose them for different sexual and reproductive health problems. Peer pressure was revealed as a major factor that influences the respondents towards their first sexual intercourse. Peers have greater influence on the positive and negative behavior of their friends. Therefore the school should emphasize on promoting peer educators and peer discussion to protect adolescents and youth from risky sexual behaviors.
