- Predicted vitamin D levels and risk of depression in the SUN Project: A prospective cohort study(Elsevier, 2024) Martinez-Gonzalez, M.A. (Miguel Ángel); Pons-Izquierdo, J.J. (Juan José); Bes-Rastrollo, M. (Maira); Silva-Sabiao, T. (Thaís) da; Cardoso-Carraro, J.C. (Julia Cristina); Sanchez-Villegas, A. (Almudena); Valer-Martínez, A. (Ana); Sayon-Orea, C. (Carmen)The current study aimed to investigate the association between predicted vitamin D status and depression in a prospective Spanish cohort of university graduates. The SUN Project is a dynamic cohort study designed to investigate multiple aspects of health and lifestyle. Participants were asked to complete a comprehensive questionnaire consisting of 556 items, that included a validated food-frequency questionnaire. Participants initially free of depression were classified as incident cases if they reported a medical diagnosis of depression during follow-up. Serum vitamin D levels were predicted by a previously validated equation. Vitamin D deficiency was defined as vitamin D levels below 20 ng/mL. Cox models were used to estimate adjusted hazard ratios (HR) and 95% confidence intervals (95% CI). We included 15,175 Spanish university graduates [mean (SD) age: 36.9 year (11.5)] followed-up for a median of 12.7 years. Among 192,976 person-years of follow-up, we identified 753 incident cases of depression. Participants with vitamin D deficiency had a 27% higher risk of depression as compared to those with vitamin D sufficiency (HR: 1.27, 95% CI: 1.09–1.48; p = 0.002) after adjusting for potential confounders. Furthermore, a significant effect modification by female sex was observed with higher depression risks associated with vitamin D deficiency in women than in men (p for interaction = 0.034). In educated middle-aged Spanish adults, we observed a direct association between vitamin D deficiency and the risk of depression, that was stronger among women.
- Encouraging natural ventilation to improve indoor environmental conditions at schools. Case studies in the north of Spain before and during COVID(Elsevier, 2022) Dorregaray-Oyaregui, S. (Sara); Arriazu-Ramos, A. (Ainhoa); Martin-Calvo, N. (Nerea); Bes-Rastrollo, M. (Maira); Monge-Barrio, A. (Aurora); López-Hernández, D. (Dolores); González-Martinez, P. (Purificación); Sánchez-Ostiz, A. (Ana)The COVID pandemic has strongly affected daily life both in Spanish schools and worldwide. Providing the best environmental conditions for children allowing face-to-face learning with healthy and safe indoor spaces is a challenge. In the present study, empirical research about how these environmental conditions change with COVID is presented comparing the situation from March 2020 to January 2021. The methodology combines surveys conducted in nine schools with a case study in a selected school where a detailed monitoring of the building was developed during both heating seasons. This data ana- lyzes the impact of the new COVID prevention protocols on indoor environmental conditions (especially those related to natural ventilation). Results show a mean CO2 reduction of 1,400 ppm, having in the sec- ond term values around 1,000 ppm, although temperatures diminished nearly 2 °C to mean values of 18 °C. Evolution of temperature and CO2 concentration throughout the day was also analyzed, being these indoor conditions especially important for the children with poorer health. Mechanical ventilation with heating recovery should complement natural ventilation, at least during the coldest months or hours of the day, although systems have to be carefully designed and installed to work effectively.

- Familia, amigos y otras fuentes de información asociadas al inicio de las relaciones sexuales en adolescentes de El Salvador(2012-01) Carlos-Chillerón, S. (Silvia); Irala, J. (Jokin) de; Ruiz-Canela, M. (Miguel); Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina); Calatrava, M. (María)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 El Salvador deberían tener en cuenta estos factores.

- First sexual intercourse and subsequent regret in three developing countries(2012-03) Carlos-Chillerón, S. (Silvia); Irala, J. (Jokin) de; Delgado-Rodriguez, M. (Miguel); Ruiz-Canela, M. (Miguel); Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina)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 8495 high schools students, aged 14-18, 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 a third of respondents reported at least one external pressure leading to first sex, and about 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 and circumstances that lower the control over their decisions concerning sex, such as external pressure (because most friends already had sex or because of partner insistence) or getting carried away by sexual arousal (through an "uncontrolled situation" or viewing sexual images) rather than by mature decisions, and this may result in later regret. Adolescents should be helped by parents, educators and policy makers to be aware of these characteristics of adolescent sex and empowered to make assertive and informed decisions concerning their sexuality.
- La educación sexual en los textos escolares españoles: evaluación de un texto alternativo(Servicio de Publicaciones de la Universidad de Navarra, 2010) Irala, J. (Jokin) de; Osorio, A. (Alfonso); Gómara, I. (Ignacio); Reparaz-Abaitua, C. (Charo)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. ------------------------Together with the increase of condom use, the spread of sexually transmitted infections, earlier ages of sexual debut and pregnancies in teenagers are also increasing. Sexual education in schools plays an important role. It is therefore important, from a public health point of view, to develop materials with contents that can help students acquire the life skills that will enable them to make free and informed decisions concerning sexuality. In this study the results of a comparative evaluation of different school texts with an alternative we have elaborated for the area of sexuality and human reproduction are presented. The extent to which these books achieve official educational objectives, promote healthy life styles and convey information enabling the prevention of risky sexual behaviours was evaluated.
- Relationships, Love and Sexuality: What the Filipino Teens Think and Feel(2009-08) Guzman, F.O. (Filipinas O.) de; Belen, V.A. (Vina A.); Irala, J. (Jokin) de; Torralba, A.N. (Antonio N.); Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina); Calatrava, M. (María)Background In order to achieve a change among teens' sexual behavior, an important step is to improve our knowledge about their opinions concerning relationships, love and sexuality. Methods A questionnaire including topics on relationships, love and sexuality was distributed to a target population of 4,000 Filipino students from third year high school to third year college. Participants were obtained through multi-stage sampling of clusters of universities and schools. This paper concentrates on teens aged 13 to 18. Results Students reported that they obtained information about love and sexuality mainly from friends. However, they valued parents' opinion more than friends'. They revealed few conversations with their parents on these topics. A majority of them would like to have more information, mainly about emotion-related topics. Almost half of respondents were not aware that condoms are not 100% effective in preventing STIs or pregnancies. More girls, compared to boys, were sensitive and opposed to several types of sexism. After adjusting for sex, age and institution, the belief of 100% condom effectiveness and the approval of pornography and sexism were associated with being sexually experienced. Conclusion There is room for further encouraging parents to talk more with their children about sexuality, specially aspects related to feelings and emotions in order to help them make better sexual choices. Indeed, teens wish to better communicate with their parents on these issues. Condoms are regarded as safer than what they really are by almost half of the participants of this study, and such incorrect knowledge seems to be associated with sexual initiation.
- Knowledge and Beliefs about Mechanism of Action of Birth Control Methods among European Women(2012-01) Carlos-Chillerón, S. (Silvia); Irala, J. (Jokin) de; Errasti, T. (Tania); Mikolajczyk, R.T. (Rafael T.); Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina)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. Less 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 (β coef.=0.22, 95%CI=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 inform women about all possible mechanisms of action of contraceptives.
- Choice of birth control methods among European women and the role of partners and providers(2011-12) Carlos-Chillerón, S. (Silvia); Irala, J. (Jokin) de; Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina)Background: The choice of a birth control method is influenced by socio-cultural and personal factors. We explored the perceived influences in women’s choice of a birth control method in five European countries (Germany, France, the U.K., Romania and Sweden), where contraception is widely used. Study design: 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 (19%). Romania had the lowest use of contraception. Oral contraceptives and intrauterine devices use were frequently suggested by providers instead of by women. Choosing the method with the partner was associated with age (OR=0.97, 95%CI 0.94-0.99), 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 intrauterine devices 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 choice of a birth control method.
