This statistic shows the percentage of U.S. teenagers that used some contraception method during their last sexual intercourse from 1988 to 2015, by gender. According to the data, in 1988, 80 percent of female respondents indicated that they used some form of contraception at their most recent sexual encounter. Comparatively, between 2011 and 2015, 90 percent of female respondents indicated that they used contraception at their last sexual encounter.

Research on the role of sex-related Internet use in adolescents’ sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents’ lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in predicting adolescents’ experience with sexual behavior. Structural equation modeling on longitudinal data from 1,132 Dutch adolescents (Mage T1 = 13.95; range 11-17; 52.7% boys) demonstrated concurrent, direct, and indirect effects between sex-related online behaviors, perceived peer norms, and experience with sexual behavior. SEIM use (among boys) and SNS use (among boys and girls) predicted increases in adolescents’ perceptions of peer approval of sexual behavior and/or in their estimates of the numbers of sexually active peers. These perceptions, in turn, predicted increases in adolescents’ level of experience with sexual behavior at the end of the study. Boys’ SNS use also directly predicted increased levels of experience with sexual behavior. These findings highlight the need for multisystemic research and intervention development to promote adolescents’ sexual health.

Overview

Sexual Health Statistics: Sexual health is a fundamental aspect of overall well-being, encompassing physical, emotional, and social dimensions of human life.

Accurate and comprehensive sexual health statistics play a crucial role in understanding the prevalence of various conditions, tracking trends, and formulating effective public health policies and interventions.

These statistics offer insights into the prevalence of sexually transmitted infections (STIs), patterns of sexual behavior, contraception usage, reproductive health outcomes, and the challenges faced by different demographic groups.

A survey of high school students in the United States found that female students were more than twice as likely to experience teen dating violence compared to male students. On average, around 13.6 percent of high school students experienced dating violence at least once in the 12 month period before the survey was conducted.

Introduction

Teenage Pregnancy Statistics: Teenage pregnancy, occurring in females aged 13 to 19, presents significant public health and socio-economic challenges.

It is influenced by factors such as lack of sexual education, socio-economic disadvantages, and family dynamics.

Teenage mothers face higher risks of health complications, and their children may experience low birth weight and developmental delays.

The impact extends to educational and economic outcomes, with affected adolescents often struggling to complete their education and secure stable employment.

Preventive measures include comprehensive sex education, access to contraception, and robust support systems.

Effective strategies require community engagement and supportive policies to address and mitigate these challenges.

This dataset collects information on sex behaviors of students attending secondary school in Bogota, Colombia. It contains 18894 observations.

According to a survey conducted in South Korea in 2024, around *** percent of teenage boys stated that they were sexually active. While a smaller share of teenage girls gave the same response, there has been a slight increase over the past decade.

We use a randomized experiment to test whether and what information changes teenagers' sexual behavior in Kenya. Providing information on the relative risk of HIV infection by partner's age led to a 28 percent decrease in teen pregnancy, an objective proxy for the incidence of unprotected sex. Self-reported sexual behavior data suggests substitution away from older (riskier) partners and toward same-age partners. In contrast, the official abstinence-only HIV curriculum had no impact on teen pregnancy. These results suggest that teenagers are responsive to risk information, but their sexual behavior is more elastic on the intensive than on the extensive margin.

Abstract During adolescence many changes occur in adolescent life. They have to develop social skills, behaviors that composes the repertoire of an individual to respond the social demands adequately. They face some situations that can cause stress, which is the reaction of the body to restore its balance after going through stressor situation. The present study aimed to investigate the correlation of social skills and stress variables: sex, age, type of school attended and grade. For this was used Psychological tests ESA (Stress Scale for Adolescents) and IHSA-Del-Prette(Inventory of Social Skills for Adolescents). The obtained results permit to conclude that there is a correlation between stress and the variables gender, age and type of school attended, as well as between the emission of social skills and the type of school attended. The hypothesis that the female students had more social skills than the students was not confirmed, nor it was confirmed that men have more difficulties in issuing the answers than women.

Goal 3: Promote gender equality/Promouvoir l’égalité des sexes Girls to Boys Ratio for Primary and Secondary

Abstract

Background: Adolescent girls in Kenya are disproportionately affected by early and unintended pregnancies, unsafe abortion and HIV infection. The In Their Hands (ITH) programme in Kenya aims to increase adolescents' use of high-quality sexual and reproductive health (SRH) services through targeted interventions. ITH Programme aims to promote use of contraception and testing for sexually transmitted infections (STIs) including HIV or pregnancy, for sexually active adolescent girls, 2) provide information, products and services on the adolescent girl's terms; and 3) promote communities support for girls and boys to access SRH services.

Objectives: The objectives of the evaluation are to assess: a) to what extent and how the new Adolescent Reproductive Health (ARH) partnership model and integrated system of delivery is working to meet its intended objectives and the needs of adolescents; b) adolescent user experiences across key quality dimensions and outcomes; c) how ITH programme has influenced adolescent voice, decision-making autonomy, power dynamics and provider accountability; d) how community support for adolescent reproductive and sexual health initiatives has changed as a result of this programme.

Methodology ITH programme is being implemented in two phases, a formative planning and experimentation in the first year from April 2017 to March 2018, and a national roll out and implementation from April 2018 to March 2020. This second phase is informed by an Annual Programme Review and thorough benchmarking and assessment which informed critical changes to performance and capacity so that ITH is fit for scale. It is expected that ITH will cover approximately 250,000 adolescent girls aged 15-19 in Kenya by April 2020. The programme is implemented by a consortium of Marie Stopes Kenya (MSK), Well Told Story, and Triggerise. ITH's key implementation strategies seek to increase adolescent motivation for service use, create a user-defined ecosystem and platform to provide girls with a network of accessible subsidized and discreet SRH services; and launch and sustain a national discourse campaign around adolescent sexuality and rights. The 3-year study will employ a mixed-methods approach with multiple data sources including secondary data, and qualitative and quantitative primary data with various stakeholders to explore their perceptions and attitudes towards adolescents SRH services. Quantitative data analysis will be done using STATA to provide descriptive statistics and statistical associations / correlations on key variables. All qualitative data will be analyzed using NVIVO software.

Study Duration: 36 months - between 2018 and 2020.

Sampling procedure

The sampling of adolescents for the household survey was based on expected changes in adolescent's intention to use contraception in future. According to the Kenya Demographic and Health Survey 2014, 23.8% of adolescents and young women reported not intending to use contraception in future. This was used as a baseline proportion for the intervention as it aimed to increase demand and reduce the proportion of sexually active adolescents who did not intend to use contraception in the future. Assuming that the project was to achieve an impact of at least 2.4 percentage points in the intervention counties (i.e. a reduction by 10%), a design effect of 1.5 and a non- response rate of 10%, a sample size of 1885 was estimated using Cochran's sample size formula for categorical data was adequate to detect this difference between baseline and end line time points. Based on data from the 2009 Kenya census, there were approximately 0.46 adolescents girls per a household, which meant that the study was to include approximately 4876 households from the two counties at both baseline and end line surveys.

We collected data among a representative sample of adolescent girls living in both urban and rural ITH areas to understand adolescents' access to information, use of SRH services and SRH-related decision making autonomy before the implementation of the intervention. Depending on the number of ITH health facilities in the two study counties, Homa Bay and Narok that, we sampled 3 sub-Counties in Homa Bay: West Kasipul, Ndhiwa and Kasipul; and 3 sub-Counties in Narok, Narok Town, Narok South and Narok East purposively. In each of the ITH intervention counties, there were sub-counties that had been prioritized for the project and our data collection focused on these sub-counties selected for intervention. A stratified sampling procedure was used to select wards with in the sub-counties and villages from the wards. Then households were selected from each village after all households in the villages were listed. The purposive selection of sub-counties closer to ITH intervention facilities meant that urban and semi-urban areas were oversampled due to the concentration of health facilities in urban areas.

Qualitative Sampling

Focus Group Discussion participants were recruited from the villages where the ITH adolescent household survey was conducted in both counties. A convenience sample of consenting adults living in the villages were invited to participate in the FGDS. The discussion was conducted in local languages. A facilitator and note-taker trained on how to use the focus group guide, how to facilitate the group to elicit the information sought, and how to take detailed notes. All focus group discussions took place in the local language and were tape-recorded, and the consent process included permission to tape-record the session. Participants were identified only by their first names and participants were asked not to share what was discussed outside of the focus group. Participants were read an informed consent form and asked to give written consent. In-depth interviews were conducted with purposively selected sample of consenting adolescent girls who participated in the adolescent survey. We conducted a total of 45 In-depth interviews with adolescent girls (20 in Homa Bay County and 25 in Narok County respectively). In addition, 8 FGDs (4 each per county) were conducted with mothers of adolescent girls who are usual residents of the villages which had been identified for the interviews and another 4 FGDs (2 each per county) with CHVs.

Research instrument

The questionnaire covered; socio-demographic and household information, SRH knowledge and sources of information, sexual activity and relationships, family planning knowledge, access, choice and use when needed, exposure to family planning messages and voice and decision making autonomy and quality of care for those who visited health facilities in the 12 months before the survey. The questionnaire was piloted before the data collection and the questions reviewed for appropriateness, comprehension and flow. The questionnaire was piloted among a sample of 42 adolescent girls (two each per field interviewer) 15-19 from a community outside the study counties.

The questionnaire was originally developed in English and later translated into Kiswahili. The questionnaire was programmed using ODK-based Survey CTO platform for data collection and management and was administered through face-to-face interview.

Cleaning operations

The survey tools were programmed using the ODK-based SurveyCTO platform for data collection and management. During programming, consistency checks were in-built into the data capture software which ensured that there were no cases of missing or implausible information/values entered into the database by the field interviewers. For example, the application included controls for variables ranges, skip patterns, duplicated individuals, and intra- and inter-module consistency checks. This reduced or eliminated errors usually introduced at the data capture stage. Once programmed, the survey tools were tested by the programming team who in conjunction with the project team conducted further testing on the application's usability, in-built consistency checks (skips, variable ranges, duplicating individuals etc.), and inter-module consistency checks. Any issues raised were documented and tracked on the Issue Tracker and followed up to full and timely resolution. After internal testing was done, the tools were availed to the project and field teams to perform user acceptance testing (UAT) so as to verify and validate that the electronic platform worked exactly as expected, in terms of usability, questions design, checks and skips etc.

Data cleaning was performed to ensure that data were free of errors and that indicators generated from these data were accurate and consistent. This process begun on the first day of data collection as the first records were uploaded into the database. The data manager used data collected during pilot testing to begin writing scripts in Stata 14 to check the variables in the data in 'real-time'. This ensured the resolutions of any inconsistencies that could be addressed by the data collection teams during the fieldwork activities. The Stata 14 scripts that perform real-time checks and clean data also wrote to a .rtf file that detailed every check performed against each variable, any inconsistencies encountered, and all steps that were taken to address these inconsistencies. The .rtf files also reported when a variable was

Contraceptive use is essential for reducing unwanted pregnancies and sexually transmitted infections (STIs) among adolescents. Sexual activity during adolescence, particularly in developing countries, remains a major public health concern with significant implications for reproductive health. Adolescents aged 10–19 undergo significant hormonal changes that contribute to heightened sexual drive and an increased likelihood of early sexual activity. However, despite widespread knowledge of modern contraceptive methods, their actual use remains low. This study aims to assess sexual activity and contraceptive use among Senior High School (SHS) adolescents and to identify key predictors of contraceptive uptake. A cross-sectional study was conducted from August to September 2022 involved 330 adolescents selected through simple random sampling. Data were analyzed using frequencies, percentages, Pearson’s chi-squared test, and binary logistic regression to examine associations between sociodemographic characteristics (age, sex, class, ethnicity, religion, residential status), sexual activity characteristics (relationship status, multiple sexual partners), awareness of contraceptives, and contraceptive use. Statistical significance was set at p ≤ 0.05 with a 95% confidence interval. Out of the total participants, 290 (87.9%) were within the age range of 15–19 years and the majority were females (n = 196, 59.4%). Approximately half (n = 166, 50.3%) were in an intimate relationship and 126 (38%) had engaged in sexual intercourse. Among sexually active adolescents, over half (n = 65, 51.6%) had their first sexual intercourse between the ages of 10–14 years and 100(79.4%) reported having ever used contraceptive, primarily condoms (n = 66, 66.0%), and pills (n = 43, 43.0%), with IUDs being the least common (n = 2, 2.0%). Sexually active adolescents who were aware of contraceptive (AOR = 6.686, 95%CI = 1.515 – 29.505, p = 0.012) had higher odds of contraceptive use. Early sexual initiation and contraceptive use are prevalent among adolescents. Comprehensive sex education and peer counseling on reproductive health are needed to address the consequences of early sexual activity without contraceptive use.

According to a survey conducted in October 2024 in the United States, teenage girls were more likely than teen boys to have cut back on their social media usage. Overall, ** percent of girls had reduced their social media time, compared to ** percent of boys.
