The World Health Organization (WHO) defines ‘sexual health as a state of physical, emotional, mental and social well-being related to sexuality; it is not merely the absence of disease, dysfunction or infirmity’ (World Health Organization, 2006). Sexual health is an important concept to globally prevent sexually transmitted disease (STDs) and unintended pregnancy, which are worldwide challenges among adolescents (Douglas and Fenton, 2013; Forsyth and Rogstad, 2015; World Health Organization, 2018, 2021a; Centers for Disease control and Prevention, 2021).
In developing countries, unintended pregnancies among adolescents aged 15–19 years are estimated to be more than 10 million pregnancies per year (World Health Organization, 2020). The unintended pregnancy rate in Southeast Asia has been increasing, with the top three rates in Lao People’s Democratic Republic (PDR), Cambodia and Thailand (UNESCO, 2018). The unintended pregnancy rate in adolescents aged 15–19 years is 28.7 cases per 1,000 (Bureau of Reproductive Health, 2018), which leads not only to health complications, but also to socioeconomic consequences (World Health Organization, 2015). STDs directly impact sexual and reproductive health (World Health Organization, 2021b). Unintended pregnancies and STDs are caused by low contraception use rates and other factors (UNICEF, 2015), and sex education is a major approach to solving these problems (Kay, Jones, and Jantaraweragul, 2010; Aragão et al., 2018; Briñez, Panqueva, and Hinojos, 2019). Currently, the COVID-19 pandemic is a barrier to adolescents’ access to those services. Consequently, UNESCO suggests that digital health sources that provide easy accessibility, privacy protection, comfort and entertaining content should be used to improve sexual health in adolescents (UNESCO, 2021).
A study in Thailand demonstrated that online media education is an effective method for preventing pregnancy in adolescents (Narkarat et al., 2021). Health literacy plays an essential role in promoting sexual health (Vamos et al., 2020; Massey et al., 2012; Fortenberry et al., 2001). Sexual health literacy is ‘the ability to understand preventive sexual health information to make informed choices, increase safe sex practices, and reduce sexual transmitted infection risk’ (Vamos et al., 2020). Another study in Thailand that applied health literacy and self-efficacy concepts in the intervention increased the intention and practice for pregnancy prevention (Thongnopakun, Pumpaibool, and Somrongthong, 2018b). There has been little research on online sexual health literacy interventions against pregnancy and STDs in adolescents during the COVID-19 pandemic. Adolescents seem to have good health and are likely to neglect sexual health, especially after exposure to sexually risky behaviors (Massey et al., 2012). Also, there was a province in the East region of Thailand which has the highest number of STDs (Department of Disease Control, 2019) including a high rate of unintended pregnancies. Therefore, the ‘Our Love, Our Control’ online program was conducted in this province, for edutainment, sexual health literacy (accessing, understanding, appraising and applying health-related information in healthcare) (Sørensen et al., 2012), and self-efficacy concepts. This study aims to determine the effects of the ‘Our Love, Our Control’ online program on sexual health literacy and behaviors among adolescents who had sexual intercourse experience and those who had none during the COVID-19 situation in Thailand.
This quasi-experimental research was conducted in a province of the East region, Thailand during February 2020 to September 2021. The intervention took place from 12 February 2021 – 25 June 2021. The study aimed to determine the effects of the ‘Our Love, Our Control’ online program on sexual health literacy and behaviors among adolescents who had sexual intercourse experience and those who had none during the COVID-19 situation in Thailand. Edutainment, sexual health literacy and self-efficacy were principal concepts of the online program. The experimental group attended the online program; whereas the control group lived their usual lifestyle. Nonetheless, the control group received a manual for unintended pregnancy and sexually transmitted disease prevention at the end of the research.
The Ministry of Public Health disclosed that this province had a childbearing rate of 30.63 per 1,000 among 15–19-year-old teenagers. The top three rates per 1,000 were 48.45, 36.83, and 36.74 in the districts of this province. Epidemiologic reports revealed that this province had the highest rate of STDs in Thailand, with 107.8 per 100,000 among 15–24 year-olds (Department of Disease Control, 2019).
The population of this study was 4,653 adolescent eighth graders from 71 public schools in this province. Two districts with the highest rate of teenage pregnancy/STDs were purposively selected as the experiment and comparison areas. The distance between both districts was 94 kilometres, and they were similar in terms of population size, number of students in school, agricultural land, and rurality. The classrooms in those schools from which the study population was drawn were randomly selected. The participating students received prior permission from their parents.
Lemeshow’s model was used to formulate the sample sizes (Lemeshow and Stroh 1988) with a confidence interval (CI) of 95%. The significant level (α) was taken as 0.05 and the power was 0.80. The mean difference was 3.46. (Krinara, Ketvatimart, and Maneechot, 2013). The sample size had a 20% attrition rate (Thongnopakun, Pumpaibool, and Somrongthong, 2018b). In the experimental group, there were 37 adolescents. The inclusion criteria were as follows: 1) Thai nationality; 2) live in the area for at least three months; 3) receive parental allowance. The exclusion criteria were as follows: 1) unable to access a smartphone; 2) being pregnant (self-reported).
A self-administered 30-minute questionnaire was given to both groups at baseline, eighth week, and twentieth week. The questionnaire consisted of four categories with 70 items as follows: 1). Sociodemographic characteristics (10 closed-ended questions, including sex, grade point average, religion, average income per day, daily sufficient income, parents’ marital status, co-living with others, and occupation of parent); 2). Attribute and pattern of sexual behaviors (15 closed-ended questions, including sexual orientation, having a boy or girl friend, sexual intercourse experiences, preventive pregnancy and STD history, consultation history about preventive pregnancy and STDs, and consequences of sexual intercourse); 3). Sexual health literacy (30 Likert’s scale questions with a total of 120 point, including accessibility of sexual health information and services, sufficient understanding of sexual health and services for practice, sexual health assessment, and decision making of sexual practice), which were mainly adapted from two studies (Sørensen et al., 2012; Ministry of Public Health, 2014); 4). Behaviors for preventing unintended pregnancy and STDs (15 Likert’s scale questions with a total of 60 point, including night life, watching pornographic media, self-management of sex drive, preventing unintended pregnancy and STDs, parental consultation about sexual health, which were mainly adapted from one study (Health Education Division Ministry of Public Health, 2014). A copy of the questionnaire can be found under Extended data (Manwong, 2022).
Intervention (12 February 2021 – 25 June 2021)
In order to increase sexual health literacy, behaviors for preventing unintended pregnancy and STDs, the ‘Our Love, Our Control’ online program was created by the researcher team and stakeholders with approval from five experts of adolescent health and behavior based on edutainment, sexual health literacy and self-efficacy concepts. There were seven main activities: ‘clear by doctor’ (accessibility of sexual health information and services), ‘sex must know’ (sufficient understanding of sexual health and services for practice), ‘help!!! I am not ready’ (sufficient understanding of sexual health and services for practice, and decision making of sexual practice), ‘condom matter’ (sufficient understanding of sexual health and services for practice), ‘believable’ (sexual health assessment), ‘my value’ (decision making of sexual practice), and ‘my choice’ (decision making of sexual practice). There were two research assistants (RAs) who were public health graduates and have worked with adolescents for at least three years. They were trained in sexual health literacy, behaviors for preventing unintended pregnancy and STDs, research methodology, data collection skills and Facebook management by a main researcher during 28 January – 11 February 2021, two weeks before the recruitment process. The edutainment media was composed of animation, infographic, live modelling techniques, short movies, and an interview with a health expert. All edutainment media were implemented via Facebook using the following methods: independent online learning, group discussion, pair discussion, group assignment, game playing, independent practice, rewarding and recognizing. The activities were held once weekly for eight weeks, for an average of 50 minutes per activity. After that, seven main activities were repeated from the ninth to the twentieth week. A copy of the program guide can be found under Extended data (Manwong, 2022).
Five experts in adolescent health and behavior from the Ministry of Education, Ministry of Public Health, and Ministry of Higher Education, Science, Research and Innovation validated the questionnaire via Google Forms and the online program. The questionnaire’s index of item objective congruence (IOC) was 0.94 and that of the online program was 0.80 (Rovinelli and Hambleton, 1976). After testing the questionnaire on 30 adolescents with similar characteristics to the participants, the Cronbach’s alpha coefficient (DeVellis, 2016) for each part was as follows: comfortable communication with parents about sexual issues was 0.90; social and environmental factors was 0.76; sexual health literacy was 0.89; and behaviors for preventing unintended pregnancy and STDs was 0.76. The online program was tested on 30 adolescents. They evaluated the program in seven activities by five-scale ratings as follows: 1) corrected content; 2) appropriate content; 3) understandable content; 4) updated content; 5) appropriate duration; 6) interest; 7) easily applying. The results showed that 95.6% strongly agreed and agreed with all seven activities. The online questionnaires were collected at baseline, eighth week, and twentieth week by sending QR code via ‘Our Love, Our Control’, closed Facebook group.
After each participants entered their data via Google Forms, all individual data were exported into a CSV file. This CSV file was imported into SPSS. The data was validated, coded and analysed using SPSS (IBM SPSS version 23×86, Burapha University license). Sexual intercourse experience was coded as 1 for who had experience, and 0 who had no experience. In part three of the questionnaires, there were five levels of ‘sexual health literacy’ scores as follows; 0=strongly disagree , 1=disagree, 2=not sure, 3=agree, 4=strongly agree. In part 4 of the questionnaires, there were five levels of ‘behaviors for preventing unintended pregnancy and STDs’ scores as follows; 0=never, 1=rarely, 2=sometimes, 3=very often, 4=always. The total scores of two dependent variables as sexual health literacy and behaviors for preventing unintended pregnancy and STDs were analyzed for comparison. The frequency distributions, mean (SD), median (IQR), minimum and maximum for continuous variables, and numbers and percentages for categorical variables were used to examine the sociodemographic characteristics for each group. Fisher’s exact test or Chi-square test was used for categorical data. Independent t-tests or Mann-Whitney tests for continuous data were used to determine differences in sociodemographic variables between the experiment and control groups. A literature review indicated that sexual intercourse experience was associated with behaviors for preventing unintended pregnancy and sexual health literacy (Thongnopakun, Pumpaibool, and Somrongthong, 2018a). Therefore, the data were sub-grouped and analysed by sexual intercourse experiences. Repeated measures of ANCOVA were used to compare the mean with 95% CIs of the adjusted variables of marital status and co-living with others, adjusted at baseline, eighth week and twentieth week. Statistical significance was considered when the p-value was <0.05.
Ethical approval was granted by Burapha University with code number: IRB1-003/2021. The approval was made in accordance with the Helsinki Declaration on studies involving human subjects. The researcher informed the participants of the research procedure in a classroom. Each participant brought the consent form back home. The parents and participants signed the informed consent form of this research if they had a mutual agreement to participate. To protect their privacy, code names were utilized, and data was kept confidential.
A total of 37 adolescents from the experimental group and 34 adolescents from the control group completed this study. Three adolescents in the control group quit the study due to the COVID-19 situation. A total of 71 adolescents participated in the final per protocol analysis.
The experimental demographic characteristics (sex, grade point average, religion, average income per day, daily sufficient income, and occupation of parent) was nearly similar to that of the control group. More than half were female. The average grade point was at least 3.00. All of them were Buddhist. The average daily income was 60 baths. Forty-seven to fifty-seven percent had sufficient daily income. More than half of the parents were agriculturists. Their sexual orientation was heterosexual, at more than 70%. There were differences in demographic variables between the experimental and control groups. In the experimental group, 40.5% of them had married parents, and 59.4% had divorced or separated parents. Conversely, in the control group 70.6% were married. Among those co-living with parents, 43.2% of the experimental group lived with parents and 37.8% lived with either mother/father. In the control group, 70.6% lived with their parents. The experimental group had higher experience of sexual intercourse than the control group. (Table 1). The full dataset can be found under Underlying data (Manwong, 2022).

There was no difference in behaviors for preventing unintended pregnancy and STDs at baseline between the experimental group and the control group. After adjusting the variables of marital status and co-living with others at the eighth week of the program, the score of behaviors for preventing unintended pregnancy and STDs showed a significant statistical difference between the experimental group and the control group (mean difference: 23.92; 95% CI: 16.56; 31.29). However, there was no difference in these scores at the twentieth week (Table 2, and Figure 1) Sexual health literacy showed no statistically significant difference between the experimental group and the control group at baseline. The score for sexual health literacy was statistically significantly different between the experimental group and the control group at the eighth week of the program (mean difference: 43.55; 95% CI: 28.10; 59.00) and at the twentieth week of the program (mean difference: 19.35; 95% CI: 0.23; 38.48) after adjusting for marital status and co-living with others (Table 2, and Figure 3).

There were no differences in behaviors for preventing unintended pregnancy and STDs at baseline between the experimental group and the control group. After adjusting the variables of marital status and co-living with others at the eighth and twentieth week, the score of behaviors for preventing unintended pregnancy and STDs was not statistically significantly different between the experimental group and the control group (Table 2, and Figure 2). There was no statistically significant difference in sexual health literacy between the experimental group and the control group at baseline. The score for sexual health literacy was statistically significantly different between the experimental group and the control group at the eighth week of the program (mean difference: 11.20; 95% CI: 3.79; 18.61) after adjusting for marital status and co-living with others. However, there was no difference in these scores at the twentieth week between the groups (Table 2, and Figure 4).
The results in adolescents who had sexual intercourse experience show that there are statistically significant differences at the eighth week of score for behaviors, and at the eighth week and the twentieth week of score for sexual health literacy. These findings demonstrate that the online program was effective and appropriate in improving behaviors and sexual health literacy for preventing unintended pregnancies and STDs. The online program involved adolescents and teachers using edutainment, media, self-efficacy concepts and various designed methods for the study. Therefore, this program may be appropriate for adolescents to prevent unintended pregnancies and STDs. The intervention in this study was consistent with the two studies that used visual media, watching a discussion between medical experts, infographic and animations (Graf and Patrick 2015; Narkarat et al., 2021). A study in Thailand also disclosed that applying different methods to modify behaviors was effective for pregnancy prevention (Thongnopakun, Pumpaibool, and Somrongthong, 2018b). During the follow up period, from the ninth to the twentieth week, the activities for increasing self-efficacy were not implemented in this study, such as brainstorming and group discussion. Moreover, communication was mostly in one direction (Feldman and Rosenthal, 2000; Koesten, 2004). Without activities for increasing self-efficacy, an insignificant difference in behavior scores was observed at the twentieth week between the experimental and the control groups. Although the average behavior score at the twentieth week in the experimental group was lower than that at the eighth week, the score was still higher than that of the baseline. During the COVID-19 lockdown, the score at the twentieth week of behaviors and sexual health literacy in the control group was higher than that at the eighth week. An increase in the score in the control group may be explained by 70.6% of the control group living with their parents. Living with parents gave them the opportunity to discuss sexual information with their parents and friends, which is supported by a post hoc analytic study that revealed that friends and family were common sources of sexual information (Graf and Patrick, 2015).
There was no difference in behaviors and sexual health literacy for preventing unintended pregnancy and STDs between the experimental group and the control group. Except for the experimental adolescents who had no sexual intercourse experience, there was a statistically significant difference in sexual health literacy scores at the eighth week compared to the control group. A study by Valois et al. (1999) observed that the number of sexual intercourse partners is associated with sexually risky behaviors. Therefore, adolescents who had sexual intercourse experience were aware that they had high sexual risk behaviors. Therefore, they may focus on improving their preventive behavior and sexual health literacy. In contrast, adolescents who have no sexual intercourse experience may not be aware of sexually risky behaviors or even gain sexual health literacy improvement.
The ‘Our Love, Our Control’ online program on sexual health literacy and behaviors during the COVID-19 situation in Thailand was effective, especially among adolescents who had sexual intercourse experience. There were statistically significant improvements in behaviors and sexual health literacy to prevent unintended pregnancies and STDs. Therefore, this program behavior is novel and practical in the COVID-19 era to prevent unintended pregnancies and STDs, particularly in adolescents who have sexual intercourse experience living in rural areas. Policy makers should focus on the promotion of sexual health among adolescents using online programs during the COVID-19 pandemic. This study was a quasi-experiment that represents real-life research during the COVID-19 outbreak; however, this design may not fully control all enrolments. To generate the results of this study, context needs to be considered.
