Abstract [en]

Treatment with serotonin reuptake inhibitors (SSRI) has been associated with an increased risk of preterm birth, but causality remains unclear. While placental CRH production is correlated with gestational length and preterm birth, it has been difficult to establish if psychological stress or mental health problems are associated with increased CRH levels. This study compared second trimester CRH serum concentrations in pregnant women on SSRI treatment (n=207) with untreated depressed women (n=56) and controls (n=609). A secondary aim was to investigate the combined effect of SSRI treatment and CRH levels on gestational length and risk for preterm birth. Women on SSRI treatment had significantly higher second trimester CRH levels than controls, and untreated depressed women. CRH levels and SSRI treatment were independently associated with shorter gestational length. The combined effect of SSRI treatment and high CRH levels yielded the highest risk estimate for preterm birth. SSRI treatment during pregnancy is associated with increased CRH levels. However, the elevated risk for preterm birth in SSRI users appear not to be mediated by increased placental CRH production, instead CRH appear as an independent risk factor for shorter gestational length and preterm birth.

Abstract [en]

Objectives: To explore young women's decision-making process for HPV vaccination and to identify their beliefs about HPV vaccination. Methods: This study employs a qualitative design. Data was collected by audio-taped interviews with 16 HPV vaccinated Swedish women, 17-26 years old. The data was analysed using latent content analysis. Results: Three themes emerged from the data: "Fear of cancer", "Reliance on vaccination" and "Mother the main motivational factor". One of the major reasons for taking the decision to be HPV vaccinated was fear of cancer: vaccination was seen as a way to protect oneself against this. The young women's decision-making surrounding HPV vaccination was based on reliance on vaccination and trust in health care. Support from the mothers of the young women and mothers' sponsorship of costs initiated HPV vaccination. Other motivational factors were advertisements and friends. Despite having been vaccinated, the young women were unaware of the relation between cervical cancer, sexual behaviour and HPV. Conclusion: These HPV vaccinated young women had limited knowledge about HPV. Therefore it is important that health professionals provide comprehensible information about HPV vaccination in attaining informed consent. In order to avoid misunderstandings, health care professionals in youth clinics and schools need to initiate discussion with young women, clarifying the relation between cervical cancer. HPV and sexual transmission.

Abstract [en]

The aim of the study was to investigate knowledge of and attitudes to sexually transmitted infection (STI) and STI prevention with special focus on human papillomavirus (HPV) and the new vaccine against HPV, among 16-year-old high school students in a Swedish context. A study-specific questionnaire was distributed to 572 first year high school students from five different high schools in a medium-sized town in Sweden. The students lacked knowledge of HPV and its association with cervical cancer. Similarly, their knowledge of the new vaccine was limited. Their attitude to condom use when having sex with a new partner was positive, but decreased if oral contraceptives were used and if they were vaccinated against an STI. The main source of information was the school, followed by youth clinics and the media. The results highlight the clinical importance for school nurses and personnel at youth clinics to inform adolescents about HPV and its association with cancer.
