    Abstract Full Text About the authors References Statistics Abstract Gender is presumed to be one of the factors causing morphofunctional variability in the human brain. The лет published findings are inconsistent with respect to gender differences in cognitive ERPs. The aim of this study was to characterize the role of gender in visual cognitive event секс potentials ERPs P in schoolchildren years. We examined children boys and girls. Our subjects had no дет or neurological disease.

    Informed parents' consent was obtained from each subject after the test procedure had been explained to him or her. All children were divided into groups according to their biological age and gender. Recordings were acquired from the occipital O1 and O2 derivations. There were no statistically significant gender differences of P amplitude.

    It should be noted that the years-old age period was characterized by the absence of gender differences in P2, P3 latency, and N2-P3 amplitude.

    The results of our study show sex differences among almost all components of cognitive event-related potentials with the exception of the amplitude of the interval P2-N2 and the amplitude of що component P in children years. The obtained data emphasize the importance of taking into account gender in the study of cognitive function ддо children years.

    Young people лет the Netherlands do not only start having sexual intercourse at a later age in compared to ; this is also the case with other forms of sex, such as kissing. The number of young people who have their first sexual experiences at a very young age, between 12 and 14, has decreased. That is good news, because young people who start having sex at a very early age are more often forced or persuaded to do so and more often have unprotected sex. Compared tomore young Dutch лет use a contraceptive method when they have секс for the first time.

    Because the pill has to be taken every day, which is easy to forget, an IUD can be a good alternative for young women. But after that, condom use strongly decreases. The лет of young Dutch people who disapprove of expressions of homosexuality has decreased strongly. Inhalf of young men and a quarter of young women disapproved of two young men kissing in public. The edition of Sex Under 25 provides a representative picture of the sexual health of young секс in the Netherlands aged The first editions of Sex Under 25 were conducted in and The study was carried out by Rutgers and Soa Aids Nederland in partnership with секс regional public health services.

    For the first time, more than half of the regional public health services recruited additional respondents to be able to provide representative figures for their секс specific region. As a result, well over 20, young people participated in the study. The findings of Sex Under 25 are used to improve information and support for young people in the Netherlands.

    Professionals who deal with the sexual health of young people in research, professional practice or policymaking provided input on the questionnaire and the themes it covers. At the conference Sex Under 25 on 20 June we will present the findings to all parties involved.

    Together with them, we will develop an action plan supported by all stakeholders in order to make sexuality education aimed at young people relevant and up to date.

    Data were pooled from the to and to continuous survey rounds of the National Survey of Family Growth. JAMA Pediatr. The developmental needs and pathways to healthy trajectories for young males remain unknown. Among NSFG survey respondents, differences in wantedness of first sexual intercourse by age at first sexual intercourse were examined, along with the associations between sexual initiation and socioeconomic covariates. The sample was largely composed of non-Hispanic white males: Sexual onset before age 13 years was reported серс by 7.

    Among males who reported having their first sexual experience before age 13 years, 8. Given the higher prevalence of first sexual бет лет age 13 years among males compared with females, understanding the variation in the timing of sexual onset among adolescent males in the United States is critical to supporting their healthy sexual development.

    Broad cultural scripts about masculinity and sex hold that men should start having sex early and have sex often. We used 2 complementary large-scale representative survey systems to assess the timing of sexual onset among adolescent рт in the United States, examine key sociodemographic correlates, and consider how reporting issues may affect estimates. The study was conducted from September to June The YRBSS, conducted by the Centers for Disease Control and Prevention, surveys middle school and high school students in classrooms using a paper-and-pencil, self-administered questionnaire.

    To examine the variation across geographic settings, we used representative YRBSS data from 8 middle school and 17 high school metropolitan areas. We used all publicly available YRBSS metropolitan area surveys and obtained permission to use some nonpublic YRBSS data from additional areas that had weighted data for at least 2 of the лет survey years. No national middle school YRBSS is conducted, but we included available metropolitan-area middle school data; these data were collected from younger students, potentially limiting recall bias in reporting age at first sexual intercourse.

    The NSFG is a periodic national probability survey of the noninstitutionalized population of females and males aged 15 to 44 years in the United States. The NSFG asked this question of all sexually experienced male respondents aged 18 years or older: Think back to the very first time you had vaginal intercourse with a female. Which would you say comes closest to describing how much you wanted that first сек intercourse to happen?

    Non-Hispanic other comprised Asian, American Indian, Alaskan Native, and Hawaiian and Pacific Islander males, but small sample sizes did not allow for separate analyses of each group. From the NSFG data, we examined maternal educational бет less than college, or completed college or more as a proxy for socioeconomic status, and community type urban, suburban, or rural.

    We also constructed indicators for survey wave. We also examined differences by age at first sexual intercourse in wantedness of first sexual intercourse among respondents aged years in the NSFG. To further compare differences in estimates between the YRBSS and NSFG, we conducted sensitivity analyses exploring alternate specifications in the NSFG, including using ACASI measures of age at first sexual intercourse, limiting the sample to those секс aged 15 to 19 years лте in school and dropping all imputed data on age at first sexual intercourse.

    To test if differences persisted across age, we produced Kaplan-Meier life table estimates of age at first sexual intercourse for both data sets. All analyses were weighted. All P values were calculated using 2-tailed Wald tests, with SEs adjusted for the complex survey снкс of each data source using Stata, version Sexual onset before age 13 years was reported by 7. However, in almost all metropolitan areas, the proportion of students who лет доо intercourse before age 13 years was higher in the middle school sample compared with the секс high school sample.

    No statistically significant differences were found by community type or by survey wave. Among respondents aged 18 to 24 years who reported having their first sexual intercourse before age 13 years, 8. These distributions were not statistically significantly different from those among males who had sexual intercourse at age 13 years or later: 5. Most of the respondents who reported having sex before age 13 years described their first sexual partner as a friend eTable 4 in the Supplement.

    This лет extends previous findings that showed a high prevalence лет sexual activity лет age 13 years, particularly among males of color, and highlights substantial variation across metropolitan areas. Other studies have found that age at first sexual intercourse is associated лет identifiable systemic barriers in communities, such as racial segregation 25 and neighborhood disadvantage.

    To this end, investments at the local level will be critical to support and promote youth development generally and healthy sexual секс specifically.

    Some of the reported first sexual experiences were characterized as unwanted and mixed feelings were common, but more than half reported their experience as wanted. However, wantedness of early sexual intercourse among male adolescents may also represent efforts to conform to traditional cultural expectations of masculinity леет may not on its own represent healthy sexual choices.

    Health education and counseling can create opportunities for young males, their families, and communities to discuss healthy sexuality, including topics of consent, coercion, and development of sexual expression. Studies have found inconsistent reporting of first sexual intercourse among black males, which is suggestive of overreporting of younger ages at first sexual intercourse. For example, black children, particularly males, often are viewed as more adult than white children, without the need for protection afforded to others.

    Early sexual onset has been associated with increased prevalence of negative physical and mental health outcomes. Emerging research suggests that the context of sexual initiation may have greater implications for sexual health than age alone. Variation exists in when cognitive, emotional, and physical development milestones are reached, and other studies have used different chronological cutoffs in their investigation of early first sexual intercourse, 4446 but there is no particular biological age at which individuals are uniformly ready for this transition.

    Policy approaches that aim to delay sexual onset may focus on the wrong drivers of behavior and may risk causing harm through stigmatization of and barriers to sex education and sexual health services. Healthy People calls for providing sex education to adolescents before age 18 years. Although the Bright О guidelines for early adolescence discuss screening and anticipatory guidance for sexual activity, as well as секс importance of individual time with a clinician, its guideline for middle childhood is focused on sexual abuse and offers less guidance on the importance of visit time alone.

    This study has several limitations. Age at first sexual intercourse is only 1 indicator of sexuality; efforts to understand the trajectories of sexual development should consider behaviors beyond vaginal-penile intercourse.

    In addition, the increased секс of earlier occurrence of first sexual intercourse in the middle school data compared то the high school YRBSS and скс age in the NSFG is suggestive of reporting bias associated with age or length of recall. These оот may have major implications for the timing of sex лет and sexual and reproductive health care.

    Health care practitioners must recognize and address all of the developmental needs and pathways to healthy trajectories for young males.
