Early Sexual Initiation

OBJECTIVES: Since exposure to sexual content and early sexual initiation among adolescents have become serious social issues in Korea, an in-depth analysis of trends in the prevalence of sexual experience among Korean adolescents is necessary to project the trends and policies required for the next 10 years. The objective of this study was to identify the contributions of age, period, and birth cohort effects on the prevalence of sexual experience in Korean adolescents.METHODS: We analyzed age-specific, period-specific, and birth cohort–specific trends in the prevalence of sexual experience among 911,502 adolescents (469,593 boys, 51.5%; 441,909 girls, 48.5%) aged 12 years to 17 years from the 2006 to 2017 Korean Youth Risk Behavior Web-based Survey. Joinpoint regression analysis was conducted to examine significant changes in the prevalence of sexual experience and to find the optimal number and location of places where trends changed.RESULTS: The prevalence of sexual experience generally increased with age in all periods in both boys and girls. In boys, the prevalence of sexual experience increased in recent periods, especially in the age group of 12-13 years, while the prevalence of sexual experience decreased in the age group of 16-17 years. In girls, the age group of 12-13 years showed an increased prevalence of sexual experience in recent periods. However, the prevalence showed a decreasing trend in the age group of 16-17 years.CONCLUSIONS: In boys and girls, sexual experience increased with age, although this tendency has slowed in recent cohorts. Therefore, early sex education is needed.

Sexually Explicit

Many adolescents use their electronic devices to send each other sexually explicit texts, photos, and videos of themselves—commonly known as sexting. This can be fun and is not usually problematic. However, if the intended recipient decides to share these sexts with a broader audience, the consequences for the depicted can be detrimental. The purpose of this study was to investigate the prevalence of (non-consensual) sext-sharing among Dutch adolescents and explore the characteristics of those who do, to gain a better understanding of factors involved in dissemination. We used data from “Sex under the age of 25,” a representative national survey on sexual health among a sample of 20,834 Dutch 12–24-year-olds. The prevalence of sext-sharing was estimated using Complex Samples. Logistic regressions were used to assess associations between demographics, school-based sexting education, sexual- and online behavior, and mental health and sext-sharing. About 4% of the adolescents reported having shared someone else's sext in the last six months. Being male, aged 12–14 years, frequent social media usage, watching online porn, sexual experience, and being subjected to sext-sharing themselves associated most strongly with sext-sharing. Our findings show that the likelihood of sext-sharing is lower in older adolescents and that it associates with the extent of adolescents' sexual curiosity and online activity. The overlap between sharing sexts of others and having one's own sext shared suggests that dissemination of personal sexual content might be normalized or used as an act of retribution. Further research could be helpful to explain the mechanisms underlying this overlap. The results of this study illustrate the importance of exposing adolescents to evidence based preventive educational interventions on sexting from 12 years onwards and not just within the context of traditional school-based sex education, but also as a part of the (online) media-literacy curriculum.

We investigated the relationship between Korean adolescents' sexual experience—including, kissing, petting, and sexual intercourse—and their alcohol consumption and use of illegal drugs and tobacco. We analyzed data taken from the responses of 74,186 adolescents who had participated in the 2012 Korean Youth Health Behavior Online Survey. Variables regarding sexual experiences, experience of contraception, and substance and alcohol use were extracted and analyzed using descriptive statistics, chi-square tests, and logistic regression. The results showed that fewer than 30% of the respondents reported always using contraception, and almost half reported rarely using contraception. The number of boys and girls reporting having had sexual experiences increased from 2 to 4 times when they also reported use of illicit drugs, smoking tobacco, or alcohol consumption. The results highlight a need for school-based sex education supported by a national policy and the provision of basic resources to reduce the incidence of unprotected sex and to improve healthy behavior of adolescents.

The article deals with the replacement of generations in Serbia, its dynamics in the second half of the 20th century, and the importance of direct determinants. It points to the major regional differences in the domain of the population reproduction among the large areas of Serbia (Central Serbia, Vojvodina, and Kosovo-Metohija). Two approaches of demographic analysis were applied: period and cohort analysis. Basic indicators, definitions, and shortcomings were presented. The results of the period analysis indicate that up until 1988 (with the exceptions of 1957 and 1981), the fertility in Serbia constantly reached a level of fertility necessary to ensure the replacement. Since 1989, the net reproduction rate has constantly been below unity. In Central Serbia and Vojvodina, the population has not been reproducing itself for more than 45 years (since 1956). The situation has been completely different in Kosovo-Metohija, where fertility has been above the level necessary to ensure reproduction during the entire second half of 20th century. The cohort analysis applied to six chosen generations (birth cohort of 1950, 1955, 1960, 1965, 1970, and 1975) indicates that in Serbia, only women born in 1960 ensured the replacement. In Central Serbia and Vojvodina, none of the studied generations succeeded in ensuring the replacement, while in Kosovo-Metohija all generations did.

Incidence And Mortality

Somach cancer is the third most common cause of cancer-related deaths worldwide. The objective of the paper was to analyze the incidence and mortality trends of stomach cancer in Central Serbia in the period between 1999–2017. Materials and Methods: trends and annual percentage change (APC) of the incidence and mortality rate with corresponding 95% confidence intervals (CI) were calculated by joinpoint regression analyses. The optimal number of Joinpoints was identified using the Monte Carlo permutation method. The trend was considered to be significantly increasing (positive change) or decreasing (negative change) when the p-value was below 0.05 (p < 0.05). Results: the total number of new cases was 16,914 (10,873 males and 6041 females) and the total number of mortality cases was 14,790 (9348 in and 5442 in females). Almost one third (30.8%) of new cases were registered in the 60–69-year age group, and new cases were significantly more frequent in males than in females (30.8% vs. 29.02%, p < 0.001). Joinpoint regression analysis showed a significant decrease of incidence trend in females during the 2000–2015 period with APC of −2.13% (95% CI: −3.8 to −0.5, p < 0.001). An insignificant decrease in incidence trend was in males with APC of −0.72% (95% CI: −2.3 to 0.9, p = 0.30). According to the joinpoint analysis, a significant decrease of mortality trends both in males during 2000–2015 with APC of −2.21% (95% CI: −1.6 to −7.5, p ≤ 0.001 and in females, during the same period, with APC of −1.75% (95% CI: −2.9 to −0.6, p < 0.001) was registered. From 2015 to 2017, a significant increase of mortality was registered with APC of 44.5% (95% CI: from 24.2 to −68.1, p ≤ 0.001) in females and in males with APC of 53.15% (95% CI: 13.5 to −106.6, p ≤ 0.001). Conclusion: a significant decrease of stomach cancer incidence trend in females and insignificant decrease of incidence trend in males were determined in Central Serbia. Based on presented results, the mortality trend decreased significantly both in males and in females during 2000–2015, and from 2015 to 2017 we recorded a significant increase in mortality in both sexes. We found significantly more new cases in women than in men in the age group of 40–49, and the mortality of stomach cancer was significantly more frequent among females compared to males in the age groups 30–39, as well as in the 50–59 age group. There is a need for improving recording and registration of new cases of stomach cancer, especially in females. Urgent primary and secondary preventive measures are needed—introducing stomach cancer screening and early detection of premalignant changes. Urgent primary and secondary preventive measures are needed.

The Impact

Companies use corporate social responsibility (CSR) disclosures to communicate their social and environmental policies, practices, and performance to stakeholders. Although the determinants and outcomes of CSR activities are well understood, we know little about how companies use CSR communication to manage a crisis. The few relevant CSR studies have focused on the pressure on corporations exerted by governments, customers, the media, or the public. Although investors have a significant influence on firm value, this stakeholder group has been neglected in research on CSR disclosure. Grounded in legitimacy theory and agency theory, this study uses a sample of Chinese public companies listed on the Shanghai Stock Exchange to investigate CSR disclosure in response to social media criticism posted by investors. The empirical findings show that investors’ social media criticism not only motivates companies to disclose their CSR activities but also increases the substantiveness of their CSR reports, demonstrating that companies’ CSR communication in response to a crisis is substantive rather than merely symbolic. We also find that the impact of social media criticism on CSR disclosure is heterogeneous. Non-state-owned enterprises, companies in regions with high levels of environmental regulations, and companies in regions with local government concern about social issues are most likely to disclose CSR information and report substantive CSR activities. We provide an in-depth analysis of corporate CSR strategies for crisis management and show that crises initiated by investors on social media provide opportunities for corporations to improve their CSR engagement.

Abstract Background Female genital cutting (FGC) inflicts life-long injuries on women and their female children. It constitutes a violation of women’s fundamental human rights and threats to bodily integrity. Though decreasing, the practice is high and widespread in Nigeria despite efforts towards its eradication. This study was conducted to perform cohort analysis of the state of FGC between the years 2009 and 2018 in Nigeria. Results The study found that that FGC has reduced over the years from 56.3% among the 1959–1963 birth cohort to 25.5% among 1994–1998 cohorts but a rise in FGC between 1994–1998 cohorts and 1999–2003 cohorts (28.4%). The percentage of respondents who circumcised their daughters reduced from 40.1% among the oldest birth cohort to 3.6% among the younger cohort. Birth-cohort, religion, education, residence, region, and ethnicity were associated with FGC. Factors associated with the daughter’s circumcision were birth-cohort, religion, residence, region, ethnicity, wealth, marital status, FGC status of the respondent, and FGC required by religion. Similar factors were found for discontinuation intention. Conclusions The practice of FGC is still high but decreasing among younger birth-cohorts in Nigeria. There is no significant change in the perception of the discontinuation of FGC. More awareness about the adverse effects of FGC, particularly among women with poor education in Nigeria will greatly reduce this cultural menace’s timely eradication.

Abstract The family is one of the most important socializing agents in adolescent sex education. However, multiple barriers to communication within families have been identified. Therefore, this study aimed to characterize and understand the processes by which parents and their adolescent children communicate about sexuality. Two questionnaires were completed by 711 fathers/mothers and 566 male/female students in 21 schools in Cali (Colombia), and 15 discussion groups were formed. The results showed that conversations about sexuality focused on protection for women and on sexuality promotion for men. Furthermore, it was found that greater fluency exists in father/son and mother/daughter conversations. The largest discrepancy between parents and teenagers was the adults' belief that it is sufficient to mention certain topics in a directive manner and the children's expectations that parents will discuss the value and dynamics of the sexual experience. Embarrassment and lack of communication tools hinder communication processes.

Knowledge And Attitudes

To document knowledge and attitudes regarding sexuality and sexual practices of male adolescent high school students in Lima, Peru, a self-administered, anonymous survey was completed by 991 male adolescents aged 12-19 as part of a School-Based Sex Education Intervention model. Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%). Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.
