    Primary prevention of gestational diabetes mellitus through nutritional factors: a systematic review
    (Bio Med Central, 2017) Bes-Rastrollo, M. (Maira); Donazar, M. (Mikel); Lopez-del-Burgo, C. (Cristina)
    Background Gestational diabetes mellitus (GDM), defined as any degree of glucose intolerance with onset during pregnancy, is increasing worldwide, mostly because obesity among women of reproductive age is continuously escalating. GDM is associated with adverse maternal and fetal outcomes. The aim of this article was to systematically review literature on the effectiveness of nutritional factors before or during pregnancy to prevent GDM. Methods We assessed the primary prevention of GDM through nutritional factors, as diet and supplements. We searched on PubMed, Cochrane Databases and ClinicalTrials.gov from inception to June 2016. Clinical trials and adjusted prospective cohort studies were included. Results Eight clinical trials and twenty observational studies assessing the association between dietary factors and primary prevention of GDM were included. Furthermore, six clinical trials and two observational studies related to supplements were also added. Only two nutritional interventions were found to significantly reduce the incidence of GDM, besides the supplements. However, the observational studies showed that a higher adherence to a healthier dietary pattern can prevent the incidence of GDM, especially in high risk population before getting pregnant. Conclusions The results indicate that there may be some benefits of some nutritional factors to prevent GDM. However, better-designed studies are required to generate higher quality evidence. At the moment, no strong conclusions can be drawn with regard to the best intervention for the prevention of GDM.

    Cyber dating abuse in adolescents: Myths of romantic love, sexting practices and bullying
    (Elsevier, 2024) Ibabe, I. (Izaskun); Lopez-del-Burgo, C. (Cristina); Albertos-San-José, A. (Aránzazu); Martínez-Soto, A. (Ainize)
    Cyber dating abuse (CDA) is a growing problem with serious consequences for adolescents, hence the importance of understanding its relationship to other variables for developing more effective prevention strategies. The current study aimed first to analyze CDA, bullying, sexting and myths of romantic love depending on sex (girls vs boys), country (Spain vs Latin American countries) and religiosity (high vs low). The second objective was to investigate the explanatory factors of CDA, examining variables associated with bullying, sexting and myths of romantic love, using structural equation modeling (SEM). The sample consisted of 3264 adolescents between 14 and 18 years old (52% girls; 32% Spanish; 68% Latin Americans). Findings showed that boys had more bullying engagement, sexting, and assumption of myths of romantic love. The highly religious group presented less sexting engagement. The results also revealed that CDA is associated with sexting and that myths of romantic love have mediational effects. Prevention programs should include strategies to help adolescents use the Internet safely and identify any type of abusive behavior both among peers and in a romantic relationship, taking into account the peculiarities of virtual interactions.

    Alcohol and difficulty conceiving in the SUN cohort: A nested case-control study
    (MDPI, 2015) Martinez-Gonzalez, M.A. (Miguel Ángel); Toledo, E. (Estefanía); Irala, J. (Jokin) de; Gea, A. (Alfredo); Chavarro, J.E. (Jorge E.); Lopez-del-Burgo, C. (Cristina)
    The role of alcohol on fertility remains unclear. We aimed to investigate the association between alcohol and specific alcoholic beverages consumption and the risk of difficulty getting pregnant. We used a case-control study nested within the Seguimiento Universidad de Navarra (SUN) cohort, a prospective, dynamic and multipurpose cohort of 21,705 Spanish university graduates, followed biennially with mailed questionnaires. We identified 686 case-control pairs, matched for age and time in the cohort. Cases were women reporting difficulty getting pregnant. Controls did not consult due to difficulty conceiving and had at least one child during follow-up. After adjustment for potential confounders, we found no association between self-reported difficulty getting pregnant and the number of alcoholic beverages consumed per week, (Odds Ratio [OR] > 5 drinks/week vs. none = 1.04, 95% Confidence Interval [CI] = 0.72-1.51). No association between types of alcoholic beverage and difficulty conceiving (OR > 5 drinks of wine/week vs. none = 1.16, 95% CI = 0.72-1.88; OR > 5 drinks of beer/week vs. none = 1.06, 95% CI = 0.82-1.37; OR > 5 drinks of spirits/week vs. none = 1.24, 95% CI = 0.84-1.64) was observed. In conclusion, we found no association between alcohol intake and risk of consulting a physician due to difficulty conceiving. More studies are needed to clearly elucidate the effects of alcohol intake on women's fertility. In the meantime, recommendations about alcohol intake to couples trying to conceive have to be given cautiously.

    Planificación familiar y consentimiento informado
    (Servicio de Publicaciones de la Universidad de Navarra, 2010) Lopez-del-Burgo, C. (Cristina); Irala, J. (Jokin) de
    La planificación familiar hace referencia a la regulación por parte de las parejas del número de hijos que desean tener, así como del espaciamiento entre los nacimientos, a través de métodos artificiales o naturales. Incluye también las medidas encaminadas a favorecer el embarazo. En la Conferencia Internacional sobre Población y Desarrollo (CIPD), celebrada en El Cairo en 1994, se ratificó “el derecho del hombre y de la mujer a obtener información y tener acceso a métodos de planificación familiar de su elección, seguros, eficaces, aceptables y económicamente asequibles” (CIPD, 1994). Así mismo, en el Informe sobre salud y derechos en materia de sexualidad y reproducción del Parlamento Europeo del año 2002, “se recomienda a los gobiernos de los Estados miembros y a los países candidatos que garanticen que las mujeres y los hombres puedan dar su pleno consentimiento con conocimiento de causa al uso de anticonceptivos, así como a métodos de conocimiento de la propia fertilidad”. La utilización de métodos de planificación familiar ha ido aumentando a lo largo de las décadas. En España, en 1983, el 33% de las mujeres utilizaban algún método de planificación familiar. En el año 2003 ese porcentaje ya era del 71,2% (Pérez, 2005). Para poder ejercer el derecho a obtener información y tener acceso a la planificación familiar, es necesario contar con servicios de asesoramiento de calidad, que se apoyen en el principio de la elección informada (United Status Agency for International Development, 1982).

    Soft drink consumption and gestational diabetes risk in the SUN
    (2018) Martinez-Gonzalez, M.A. (Miguel Ángel); Bes-Rastrollo, M. (Maira); Irala, J. (Jokin) de; Donazar, M. (Mikel); Basterra-Gortari, F.J. (Francisco Javier); Lopez-del-Burgo, C. (Cristina)
    Background & aims: Gestational diabetes mellitus (GDM) prevalence is increasing worldwide. To the best of our knowledge the specific evaluation of soft drink consumption as a risk factor for developing GDM has only been conducted in the Nurses' Health Study II. Objective: To investigate the incidence of GDM according to soft drink consumption in the SUN project. Design: The “Seguimiento Universidad de Navarra” (SUN) project is a prospective and dynamic cohort which included data of 3396 women who notified at least one pregnancy between December 1999 and March 2012. A validated 136-item semi-quantitative food frequency questionnaire was used to assess soft drink consumption. Four categories of sugar-sweetened soft drink (SSSD) and diet soft drink (DSD) consumption (servings) were established: rarely or never (<1/month), low (1e3/month), intermediate (>3/month and 1/week) and high (2/week). Potential confounders were adjusted through non- conditional logistic regression models. Results: During the follow-up, we identified 172 incident cases of GDM. After adjusting for age, baseline body mass index, family history of diabetes, smoking, total energy intake, physical activity, parity, fast- food consumption, adherence to Mediterranean dietary pattern, alcohol intake, multiple pregnancy, cardiovascular disease/hypertension at baseline, fiber intake, following special diet and snacking, SSSD consumption was significantly associated with an increased risk of incident GDM, with multivariable adjusted odds ratios (OR) of 2.03 (95% confidence interval [CI]: 1.25e3.31) and 1.67 (95% CI: 1.01e2.77) for the highest and intermediate categories, respectively, versus the lowest category (p for linear trend: 0.006). Conversely, DSD consumption was not associated with GDM incidence (adjusted OR: 0.82; 95% CI: 0.52e1.31) for the highest versus the lowest category (p for linear trend: 0.258). Additional sensitivity analyses did not change the results. Conclusion: Higher consumption of SSSDs before pregnancy was an independent risk factor for GDM, however, no association was observed between DSD consumption and GDM risk.

    Prevalence of paid sex and associated factors among women and men attending HIV voluntary counseling and testing in Kinshasa, Democratic Republic of the Congo: a prospective cohort
    (Springer, 2024) Carlos-Chillerón, S. (Silvia); Burgueño, E. (Eduardo); Makonda, B. (Benit); Díaz-Herráez, P. (Paula); Irala, J. (Jokin) de; Reina, G. (Gabriel); Lopez-del-Burgo, C. (Cristina); Beltramo, C. (Carlos)
    Paid sex is associated with HIV and other sexually transmitted infections, which are highly prevalent in Sub-Saharan Africa (SSA). However, few data exist on this sexual practice among the general population in SSA, including the Democratic Republic of the Congo, where data on paid sex mainly comes from sex workers. In the DRC, most HIV Voluntary Counseling and Testing (VCT) centers do not discuss paid sex as a risk factor. Thus, we aimed to analyze the prevalence of paid sex, its associated factors and association with HIV among women and men attending HIV VCT at a reference hospital in Kinshasa. From 2016 to 2018, the Observational Kinshasa AIDS Initiative cohort analyzed the impact of HIV VCT on changes in HIV knowledge, attitudes, and sexual behaviors at follow-up. Participants aged 15–69 years were HIV tested and interviewed at baseline and at 6- and 12-month follow-ups. At baseline, participants were asked about their history of “ever” having had exchanged sex for money. At both follow-ups, the frequency of this practice was referred to as “the previous 6 months.” Descriptive, bivariate, and multivariate logistic regression analyses were carried out to evaluate the prevalence of paid sex, its associated factors, and the association between paid sex and HIV. Statistical analyses were performed with Stata 15.1. Among 797 participants at baseline, 10% of those sexually experienced reported having ever had paid sex (18% men and 4% women, p<0.001). At 6 and 12-month follow-ups, 5% and 2%, respectively. Paid sex was signifcantly and independently associated with being male (aOR=2.7; 95% CI=1.4–5.2), working or studying (aOR=2.8; 95% CI=1.5–5.0), daily newspaper reading (aOR=4.4; 95% CI=1.7–11.2); daily/weekly alcohol consumption (aOR=3.3; 95% CI=1.8–6.1), frst sexual intercourse before age 15 years (aOR=2.3; 95% CI=1.1–5.0), multiple sexual partners (aOR=4.1; 95% CI=2.2–7.7), and extragenital sexual practices (aOR=2.4; 95% CI=1.3–4.4). A high religiosity (daily/weekly church attendance and praying) was inversely associated with paid sex (aOR=0.1; 95% CI=0.0–0.4). The high prevalence of paid sex among people attending HIV VCT in Kinshasa, associated with other sexual and consumption risk behaviors, highlights the need to include paid sex among the risk factors mentioned in HIV prevention counseling.

    La vivencia de la sexualidad en las parejas infértiles/estériles
    (Universidad Nacional de Educación a Distancia, 2017) Lopez-del-Burgo, C. (Cristina)
    Antecedentes: La infertilidad supone una crisis vital para la pareja. Son abundantes los estudios sobre su impacto psicológico en la mujer y el varón. Se han descrito también disfunciones sexuales debidas a la infertilidad. Objetivo: Realizar una revisión bibliográfica sobre la vivencia de la sexualidad en las parejas infértiles/estériles y revisar si los protocolos de atención a parejas infértiles incluyen el abordaje de la sexualidad. Métodos: Búsqueda en PubMed de estudios descriptivos, analíticos, revisiones y meta- análisis que evalúen la presencia de disfunciones en personas infértiles. Búsqueda de guías de sociedades científicas sobre el abordaje de la infertilidad. Resultados: En las parejas infértiles se han descrito fundamentalmente disminución del deseo sexual, problemas de excitación y orgasmo en la mujer y disfunción eréctil y trastornos eyaculatorios en el varón. Los estudios revisados tienen importantes limitaciones metodológicas que impiden realizar generalizaciones a la población infértil y determinar si la infertilidad aumenta el riesgo de disfunciones sexuales. Existen guías de atención a las parejas infértiles/estériles que incluyen recomendaciones sobre la evaluación y el abordaje de la vivencia de la sexualidad, aunque la mayoría se dirigen a las parejas que recurren a las terapias de reproducción asistida. Conclusiones: Las parejas infértiles pueden presentar disfunciones sexuales. Son aconsejables más estudios, adecuadamente diseñados, para estimar la prevalencia real de disfunciones sexuales en las parejas fértiles e infértiles y dilucidar si la infertilidad es un factor de riesgo para desarrollar dichas disfunciones. De esta manera se mejoraría la información que se ofrece a las parejas infértiles/estériles.

    Leisure time activities in adolescents predict problematic technology use
    (Springer, 2023) Ibabe, I. (Izaskun); Lopez-del-Burgo, C. (Cristina); Albertos-San-José, A. (Aránzazu)
    The problematic use of technology of children and adolescents is becoming a growing problem. Research has shown that excessive technology use predicts a variety of psychological and physical health problems. The aim of this study was to analyze the role of leisure time activities (structured and unstructured) in adolescents as a predictor of problematic technology use. Participants were 7723 adolescents, of which 55% were girls, from four Spanish-speaking countries (Chile, Spain, Mexico, and Peru) between the ages of 13 and 18 years. The evaluation instrument applied was the YOURLIFE project self-report questionnaire. Two executive functions were measured: goal setting and inhibitory control. Using structural equation modeling, findings indicated that structured leisure time activities predicted less PTU, whereas unstructured activities predicted more PTU, MLχ2 (69, N = 7723) = 806.60; CFI = 0.929, RMSEA = 0.042, and the model had good predictive capacity for PTU (R2 = 0.46). Structured and unstructured activities also showed indirect effects on PTU through executive functions. As adolescents spent more time in unstructured leisure activities, poorer goal setting, inhibitory control skills, and more PTU were found. The opposite was true for structured leisure time activities. Implications of structured leisure activities to develop executive functioning and to prevent PTU for adolescents are discussed.

    Activities and relationships with parents as key ecological assets that encourage personal positive youth development
    (Wiley, 2021) Balaguer-Estaña, A.J. (Álvaro J.); Orejudo, S. (Santos); Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina); Rosa, P.A. (Pedro Antonio) de la
    Scientific literature has shown contextual factors thatpredict youth development, and family variables are themost important ones. In this study, we propose a modelthat explains the relation between family variables (re-lationship with parents and family activities) and PersonalPositive Youth Development (assessed through Life sa-tisfaction, Interiority, and Self‐control), across differentcultures. We recruited 2867 adolescents aged 12–18 years(52% female) from three countries: Spain, Mexico, andPeru. They completed an anonymous questionnaire. Werun exploratory and confirmatory factor analyses, andstructural equation modelling, testing for invariance acrosscountries and sexes. In all subsamples, positive family re-lationships were associated with adolescents' Life Sa-tisfaction. In addition, time invested on family activities wasassociated with Interiority and with Self‐control. However,some differences across cultures and sex were found in thespecific associations. Theoretical and practical implicationsare discussed regarding how to improve adolescent devel-opment through family life

    Spanish women’s attitudes towards post-fertilization effects of birth control methods
    (2010-07) Irala, J. (Jokin) de; López-Guzmán, J. (José); Osorio, A. (Alfonso); Lopez-del-Burgo, C. (Cristina); López-de-Fez, C.M. (Carmen M.)
    Objective: Some methods of family planning may occasionally work after fertilization or implantation. These effects may be important to some women. We explored Spanish women’s attitudes towards these potential mechanisms of action of family planning methods. 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 postfertilization effects. Results: The majority of women were married, held an academic degree 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 postfertilization effects. Conclusion: The possibility of postfertilization effects may influence Spanish women’s choice of a FP method. Information about mechanisms of action of birth control methods should be disclosed to women so that they can make informed choices.
