In the Democratic Republic of Congo no previous studies have assessed the factors associated with different patterns of condom use and with multiple sexual partners, and the association between condom use simultaneously taking into account multiple sexual partnerships, and HIV infection. We carried out a prospective case¿control study. From December 2010 until June 2012, 1630 participants aged 15¿49 getting HIV Voluntary Counseling and Testing in a hospital in Kinshasa were selected. Cases were new HIV diagnosis and controls were HIV-negative participants detected along the study period. We recruited 274 cases and 1340 controls that were interviewed about HIV-related knowledge, attitudes and behaviours. Among cases there was a high prevalence of multiple lifetime and concurrent sexual partnerships (89.8% and 20.4%, respectively) and most cases never used condoms with only 1.5% using them consistently. Condom use and multiple partnerships were associated with male, single and high-educated participants. An association was found between multiple lifetime partners and `any condom use¿ (OR¿=¿2.99; 95%CI: 2.14¿4.19) but not with consistent use. Both having two or more multiple concurrent sexual partners or not using condoms were variables similarly and highly associated to HIV risk. The association found between having two or more concurrent sexual partners and HIV was slightly higher (OR¿=¿3.58, 95%CI:2.31¿5.56) than the association found between never condom use and HIV (OR¿=¿3.38, 95%CI:1.15¿9.93). We found a high prevalence of multiple lifetime sexual partners and an extremely high prevalence of inconsistent condom use, both strongly associated with HIV seropositivity. Local programmes would benefit from comprehensive interventions targeting all behavioural and sociocultural determinants.

This cross-sectional study assesses the association between age of sexual initiation during adolescence and a selection of well-being outcomes regarding that first relationship. High-school adolescents from El Salvador (2,686) and from Peru (3,399) replied to a paper-pencil questionnaire. Those who were sexually initiated replied to several questions regarding their age at sexual initiation, condom use, satisfaction and reasons/circumstances for that sexual relationship. Approximately 19% of participants were sexually initiated (n=1,179). After retaining participants with valid responses and with sexual initiation ages between 13 and 17, the final sample for this paper consisted of 996 sexually initiated participants (526 Salvadorians and 470 Peruvians). Multiple logistic regression analyses showed that those who initiated sex at earlier ages had worse outcomes compared to those who initiated at older ages. Specifically, they had lower odds of having used a condom, of having good memories of that experience and of having had that first relationship because they were in love. Conversely, they had higher odds of having had that first sexual relationship as a result of peer pressure, because of partner pressure, or as a consequence of different forms of impaired autonomy. Results show that sex at earlier ages is associated with worse adolescent health and well-being outcomes.

In this paper we study whether parental knowledge of adolescents' activities varies according to socio-demographic variables, and we analyze the possible association between parental knowledge patterns and certain risk behaviors among adolescents. A cross-sectional study was performed with representative samples of high-school students in Peru and El Salvador. A questionnaire assessed risk behaviors, as well as possible determinants, including parental knowledge. The questionnaire was answered by 6208 adolescents. We observed that the greater the degree of knowledge, the lower the frequency of risk behaviors among youth. The degree of knowledge was inversely associated with children's age, and we observed that being female was associated with a greater degree of parental knowledge. The study shows that parents' supervision criteria might be influenced by gender stereotypes, which would have a harmful effect on young males, as the lower degree of knowledge puts them at higher odds of risk behaviors.

BACKGROUND: Considering the high percentage of couples in which one or both members are HIV negative, the frequency of transmission among non-regular partners and the probabilities of non-disclosure, attention should be paid to people getting a negative HIV test at the Voluntary Counseling and Testing (VCT). Research has shown that a negative HIV test may be followed by a change in sexual behaviours. In Sub-Saharan Africa, where most HIV infections occur, there are few studies that have analysed the factors associated with changes in sexual risk behaviours after a negative HIV test at the VCT clinic. The aim of this project is to evaluate the specific factors associated with changes in sexual behaviours, three months after a negative result in an HIV test, and to analyse the effect of counseling and testing on HIV-related knowledge of participants in an outpatient centre of Kinshasa (Democratic Republic of Congo). METHODS AND DESIGN: Prospective cohort study from December 2014 until March 2016. People 15-60 year old that received VCT at Monkole Hospital (Kinshasa) were followed three months after they got a negative HIV test. In a face-to-face interview, participants replied to a baseline and a follow-up research questionnaire on HIV-related knowledge, attitudes and behaviours. At follow-up respondents were also offered a new HIV test and additional HIV counseling. Four hundred and fifteen participants completed the baseline questionnaire and 363 (87 %) came back for their 3-month follow up. DISCUSSION: This is the first longitudinal study in the DRC that evaluates the factors associated with changes in sexual behaviours after a negative HIV test at the VCT. Participants attending the VCT services within a clinical setting are a good study population as they can be good transmitters of preventive information for other people with no access to health facilities.

Introduction: Sexually transmitted infections and unplanned pregnancies affect adolescent sexual health and are serious public health concerns. They result from sexual intercourse in adolescence, which is usually associated with multiple partners, unprotected sex, and condom misuse. This behavior is related to socio-ecological factors that influence lifestyles. The YOURLIFE project aims to find out what young people think and feel about relationships, love, and sexuality, and to assess the associations between these thoughts and attitudes, adolescents' social factors, and sexual health. Materials and Equipment: An international school-based study with a cross-sectional and optional subsequent longitudinal design. Three online questionnaires designed for adolescents aged 13/14, 15/16, and 17/18, respectively, will be used. A matching coding system will allow longitudinal follow-up when adolescents reply to follow-up surveys. Questionnaires will include questions related to sociodemographic data; information/communication technologies; leisure time; parental supervision; influences of parents/friends; information sources; messages perceived; and sexuality-related knowledge, attitudes, and opinions. The second and third questionnaires for participants aged 15/16 and 17/18 will also contain variables concerning sexual behavior. Schools will be able to use their results to tailor educational approaches targeting the needs of their students. Multivariate analyses will be performed using the larger international dataset. Expected Impact Of the Study On Public Health: The YOURLIFE project will collect comprehensive information about the socio-ecological determinants of the sexual risk-taking of schooled adolescents worldwide. Effective preventive programs could be subsequently designed and tailored to the specific determinants of adolescents from different schools and settings, and also, when analyzed globally, to public health professionals.

Background: While international studies have reported the superiority of the authoritative style (which combines parental involvement with demandingness), some studies in Spain and in other countries have found that the indulgent style (involvement without demandingness) might be just as good or even better. This study aims to discern whether the differences are cultural or methodological. Method: 306 adolescents from high schools in Madrid and Valencia (Spain) answered a questionnaire that included two parenting style instruments (SOC-30 and PSI), together with a self-esteem scale (AF5) and a question on academic performance. Results: Concordance between the two instruments assessing parenting styles was poor. When associating parenting styles (according to the SOC- 30) with outcomes (self-esteem and academic achievement), results were similar to previous studies in Spain. But if we use the PSI, results were similar to studies in Anglophone countries: the authoritative style achieved the best outcomes. Conclusions: The discrepancies found between studies carried out in Spain and in Anglophone countries do not seem to be due to differences between cultures, but to methodological differences (i.e., differences between the instruments used). If we use the same instruments that were used in Anglophone countries, the most effective parenting style is still the authoritative.

OBJECTIVES: This study intends to evaluate whether the belief that condoms are 100% effective in protecting against HIV infection is associated with sexual risk behaviours among youth. METHODS: A cross-sectional study was performed in representative samples of high-school students in the Philippines, El Salvador and Peru. Participants completed a self-administered questionnaire. Students were asked about the risk of HIV transmission if one has sex using condoms. They were also asked to indicate whether they had ever had sexual relations and whether they used a condom in their first sexual relation. The sample was composed of 8994 students, aged 13-18. RESULTS: One out of seven adolescents believed condoms are 100% effective (safe-sex believers). Those adolescents were 82% more likely to have had sex than those without such belief, after adjusting for confounders (OR=1.82; 95% CI 1.51 to 2.21). On the contrary, no association was found between risk perception and condom use. Subgroup and sensitivity analyses produced similar results. CONCLUSIONS: This is, to the best of our knowledge, the first study conducted specifically to evaluate this phenomenon and that has used the same questionnaire and the same data collection protocol in three different developing countries from Asia, Central and South America. These results reasonably suggest that there could be an association between safe sex beliefs and sexual initiation. Longitudinal studies are needed to better understand this possible association as it could influence how to better promote sexual health.

The common statistical indicator "mean age of first sex" can be misinterpreted by youth to indicate that most of their peers of the same age are sexually initiated, when this is not usually the case. This can jeopardize efforts to delay sexual initiation. University students were randomly assigned to one of two versions of an anonymous survey. They were asked to estimate how common sexual initiation was at a given age upon being presented with statements with different wordings, such as the "mean age of first sex" or "proportions of youth at different ages having had sex." Their interpretations were compared using logistic regression. Students who were assigned surveys using the indicator "mean age" of sexual initiation had higher odds of overestimating the extent of sexual initiation compared to those assigned surveys using percentages as the indicator, even after adjusting for student's sex and degree. We encourage the use of the "percentage" of youth, at different ages, who are sexually initiated as a more reliable indicator.

Aims and Objectives: To assess women's attitudes towards the mechanisms of action of birth control methods. Background: When addressing women's knowledge of and attitudes towards birth control methods, researchers frequently focus on side effects, effectiveness or correct use. Women's opinions about mechanisms of action have been much less investigated, and research is usually concentrated on the EC pill. Design: Cross-sectional study. Methods: Women, aged 18-49, from Germany, France, the UK, Sweden and Romania were randomly selected (n = 1137). They were asked whether they would use a method that may work after fertilisation or after implantation and whether they would continue using it after learning it may have such effects. Logistic regression was performed to evaluate the influence of certain characteristics on women's attitudes. Results: Almost half of women in Romania and Germany would not use methods with postfertilisation effects, while the lowest percentages were found in Sweden and in France. Regarding methods with postimplantation effects, higher percentages were found in all the countries. Highly educated women and those using a highly effective method were more likely to use methods with postfertilisation effects. On the contrary, married women, those who stated that human life begins at fertilisation and women with middle/high religiosity were less likely to consider using methods that may act after fertilisation. Conclusions: One-third of European women reported that they would not consider using a method that may have postfertilisation effects. Relevance To Clinical Practice: Given that postfertilisation effects may not be acceptable to some women, informing them of which methods may have these effects is essential to obtaining complete informed consent and to promoting women's autonomy.

ICS Purpose Adolescents who engage in sex can be affected by a range of negative physical and psychological consequences. We intend to analyze the reasons behind first sex, regret, and the association between reasons and regret. Methods A questionnaire was implemented to 8,495 high schools students aged 14¿18 years residing in the Philippines, El Salvador, and Peru. Sexually active participants responded whether several circumstances were reasons involved in their first sexual relationship. They also responded whether they regretted having already had sexual relationships. Results More than one-third of respondents reported at least one external pressure leading to first sex, and about one-half reported at least one reason implying getting carried away by sexual arousal. More females affirmed they regret having already had sex. Logistic regression shows that reasons for first sex associated with regret were partner insistence, ¿uncontrolled situations,¿ and seeing sexual images. These reasons were associated with regret even when love was also reported as related to first sex. Conclusions Adolescent sexual experience is often motivated by pressure (such as external pressure [because most friends already had sex or because of partner insistence]) and circumstances (such as getting carried away by sexual arousal [through an ¿uncontrolled situation¿ or viewing sexual images]) that lower the control over their decisions concerning sex, rather than by mature decisions, and this ma

ICS Objetivo. El objetivo de este estudio es comprobar cómo influyen en el inicio de la actividad sexual de los jóvenes salvadoreños los mensajes que reciben sobre cuestiones de sexualidad, afectividad y ocio a través de la familia, los amigos y los medios de comunicación. Métodos. Estudio transversal a partir de una muestra representativa de 2 615 estudiantes (de 13 a 19 años) de El Salvador. Se utilizó un muestreo sistemático aleatorio para seleccionar 30 colegios. Se recogieron aspectos sociodemográficos, estilos de vida y fuentes de información sobre sexualidad y amor utilizadas por los jóvenes. Resultados. La edad media de los jóvenes fue de 15 años (DE = 1,8). En total 638 (24,4%) jóvenes afirmaron haber tenido relaciones sexuales. Los siguientes factores se asociaron con una mayor probabilidad de haber tenido relaciones sexuales: percibir que los hermanos (OR = 1,8, IC 95%: 1,2¿2,7) o los amigos (OR = 1,7, IC 95%: 1,3¿2,2) apoyan que se tengan relaciones sexuales. Como factores protectores se encontraron la supervisión de los padres (OR = 0,5, IC 95%: 0,4¿0,7); recibir mensajes que apoyan la abstinencia por parte de amigos (OR = 0,7, IC 95%: 0,6¿1,0) o hermanos (OR = 0,7, IC 95%: 0,5¿0,8) y recibir mensajes favorables al matrimonio por parte de los padres (OR = 0,4, IC 95%: 0,3¿0,6). Conclusiones. Los mensajes de la familia y amigos son factores que parecen influir en el inicio de las relaciones sexuales de los jóvenes. Los programas de promoción de la salud sexual en

ICS Background: Adequate knowledge is essential for making informed decisions. We attempted to determine the level of knowledge about mechanisms of action of birth control methods in five representative samples of European women. Study Design: Randomly selected women, aged 18-49 years, completed an anonymous survey in Germany, France, the UK, Sweden and Romania (N=1137). Participants were asked about how contraceptive methods work and if providers should inform them about this issue. Multiple linear regression was used to evaluate women's characteristics associated with their knowledge of mechanisms of action. Results: The majority of women identified the unequivocal mode of action of condoms, sterilization and abortion. Fewer than 2% identified all possible mechanisms of action of hormonal contraceptives and intrauterine devices. Highly educated women correctly identified the mechanism or mechanisms of action of more methods than less educated women (beta=0.22, 95% confidence interval 0.01-0.43). Regardless of their sociodemographic characteristics and their belief about when human life begins, most women (75%) stated that the provider should inform them about possible postfertilization effects. Conclusions: European women have low knowledge about mechanisms of action of several contraceptive methods. The majority want to be informed about possible postfertilization effects. Since adequate knowledge is essential for making informed decisions, providers are encouraged to info

Background: The choice of a birth control method is influenced by sociocultural and personal factors. We explored the perceived influences in women's choice of a birth control method in five European countries (Germany, France, the UK, Romania and Sweden), where contraception is widely used. Study Design: This is a cross-sectional study of 1137 randomly selected women aged 18-49 years. An anonymous, 31-item questionnaire related to birth control methods was used. Logistic regression was used to identify variables associated with partner participation in choice of a contraceptive. Results: Oral contraceptives were mainly used in Germany (54.3%), France (50.5%) and Sweden (34.6%) and condoms in the UK (29.6%) and Romania (22.9%). Sweden showed the highest use of intrauterine devices (IUD, 19%). Romania had the lowest use of contraception. Oral contraceptives and IUDs use were frequently suggested by providers instead of by women. Choosing the method with the partner was associated with age [odds ratio (OR)=0.97, 95% confidence interval (CI) 0.94-0.99], being a university graduate (OR=1.59, 95% CI 1.01-2.29), married (OR=1.52, 95% CI 1.01-2.29) and with using a method that requires partner's cooperation (OR=8.18, 95% CI 5.46-12.27). Conclusions: Hormonal contraceptives and lUDs are commonly recommended by providers rather than requested by women. Partner preferences are taken into account when his cooperation in the use of the method is needed. As fertility care is a male and female issue, there is still more room for actively involving both women and men in their choice of a birth control method.

Con frecuencia los estudios relacionados con el altruismo lo abordan desde constructos psicológicos como la memoria, la afectividad, la motivación o el aprendizaje. Son escasas, en cambio, las aproximaciones desde la voluntad y la virtud. El presente artículo pretende vincular estos conceptos con ese campo de investigación, para aportar nuevas claves de interpretación sobre la educación del altruismo y para el diseño de estrategias pedagógicas en este campo. Algunas evidencias empíricas muestran que los constructos psicológicos resultan insuficientes para explicar la conducta altruista y su formación, mientras que recurriendo también a la visión aristotélica de la voluntad y de la virtud se alcanza una comprensión más íntegra y pedagógica del altruismo como objeto educativo.

Objective: Some methods of family planning, such as oral contraceptives, emergency pill or intrauterine device, may occasionally work after fertilization. These effects may be important to some women. We explored Spanish women's attitudes towards contraceptive choices that may have occasional post-fertilization mechanisms of action. Study design: Cross-sectional study in a Spanish representative sample of 848 potentially fertile women, aged 18¿49. Data were collected using a 30-item questionnaire about family planning. Logistic regression was used to identify variables associated with women's attitudes towards post-fertilization effects. Results: The majority of women were married, had completed high school and had at least one child. Forty-five percent of women would not consider using a method that may work after fertilization and 57% would not consider using one that may work after implantation. Forty-eight percent of the sample would stop using a method if they learned that it sometimes works after fertilization, increasing to 63% when referring to a method that sometimes works after implantation. Women who believe that human life begins at fertilization, those who believe it is important to distinguish between spontaneous and induced embryo losses and women who report having a religion were less likely to consider the use of a method with some post-fertilization effects.Conclusion:The possibility of post-fertilization effects may influence Spanish women's choice of a family planning method. Information about mechanisms of action of birth control methods should be disclosed to women so that they can make informed choices.

Junto al aumento de la utilización de preservativos, asistimos también al aumento de la transmisión de infecciones de transmisión sexual, al adelanto en la edad de inicio de relaciones sexuales y al aumento de embarazos en adolescentes. En este sentido cobra especial importancia la educación sexual recibida en el último tramo de la educación obligatoria. Es importante, desde el punto de vista de la Salud Pública, desarrollar contenidos que permitan al alumno adquirir habilidades sociales que le ayuden a tomar decisiones más libres e informadas encaminadas a retrasar el inicio de las relaciones sexuales. En este trabajo se presentan los resultados de la evaluación comparativa sobre los contenidos de los libros escolares del área de Biología de 3º de la ESO en su capítulo sobre sexualidad y reproducción humana con un texto escolar alternativo. Se evalúa si posibilitan la consecución de los objetivos educativos señalados en el currículo y si promocionan estilos de vida saludables que lleguen a prevenir conductas de riesgo.
