Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Perinatal depressive symptoms among women remain a global burden. Improvements in self-efficacy among public health professionals (PHPs) in primary healthcare settings to detect and manage perinatal depressive symptoms among women are needed.The aims of this thesis were to: identify prevalence and risk factors associated with perinatal depressive symptoms among women; to explore and describe life situation and support among women with antenatal depressive symptoms (ADS) and their partners; and to improve self-efficacy of PHPs in detection and management of perinatal depressive symptoms in Sakonnakhon province in Thailand. Qualitative and quantitative studies with different types of data collection methods were used.Study I determined prevalence of ADS and associated risk factors among 449 Thai women in late pregnancy using the Edinburgh Postnatal Depression Scale (EPDS). The prevalence was 46.8% and associated risk factors were insufficient money, being a teenager, low psychological well-being, low self-esteem and low sense of coherence.Study II explored and described life situation and support during pregnancy among women with ADS and their partners using semi-structured interviews. Four categories emerged: Having obstacles in life, Facing life situation, Enhancing confidence and Dissatisfaction with help.Study III determined risk factors associated with postpartum depressive symptoms at one month among 319 women and at three months among 276 women. Risk factors at one month were antenatal psychological well-being, non-exclusive breastfeeding, low personal income and caregiver not a mother; risk factors at three months were unintended pregnancy, low personal income/month, low self-esteem, low psychological well-being and low maternal competence.Study IV evaluated a self-efficacy improvement programme (SIP) intended to increase PHPs’ self-efficacy in efforts to detect and manage perinatal depressive symptoms among women. After the SIP, PHPs in the intervention group (n=33) had higher self-efficacy scores than PHPs in the control group (n=33). Four categories emerged in qualitative evaluation: Having confidence, Changing knowledge and attitudes, Increasing perception of an important role, and Increasing awareness of performed function.Women who are at increased risk for perinatal depressive symptoms should be screened using the EPDS. Health care professionals should involve expectant fathers in ANC process. The SIP enhances PHPs’ ability to detect and manage perinatal depressive symptoms.

- The genetics and clinical consequences of resting heart rate (RHR) remain incompletely understood. Here, the authors discover new genetic variants associated with RHR and find that higher genetically predicted RHR decreases risk of atrial fibrillation and ischemic stroke. Resting heart rate is associated with cardiovascular diseases and mortality in observational and Mendelian randomization studies. The aims of this study are to extend the number of resting heart rate associated genetic variants and to obtain further insights in resting heart rate biology and its clinical consequences. A genome-wide meta-analysis of 100 studies in up to 835,465 individuals reveals 493 independent genetic variants in 352 loci, including 68 genetic variants outside previously identified resting heart rate associated loci. We prioritize 670 genes and in silico annotations point to their enrichment in cardiomyocytes and provide insights in their ECG signature. Two-sample Mendelian randomization analyses indicate that higher genetically predicted resting heart rate increases risk of dilated cardiomyopathy, but decreases risk of developing atrial fibrillation, ischemic stroke, and cardio-embolic stroke. We do not find evidence for a linear or non-linear genetic association between resting heart rate and all-cause mortality in contrast to our previous Mendelian randomization study. Systematic alteration of key differences between the current and previous Mendelian randomization study indicates that the most likely cause of the discrepancy between these studies arises from false positive findings in previous one-sample MR analyses caused by weak-instrument bias at lower P-value thresholds. The results extend our understanding of resting heart rate biology and give additional insights in its role in cardiovascular disease development.
