- Objective: To map the knowledge about and attitudes toward birth control methods among women in Kathmandu, Nepal, and to compare the results between women seeking an induced abortion and a control group. Method: This was a cross-sectional cohort study with matched controls. Women aged 15-49 years seeking medical care at the Department of Gynecology and Obstetrics at Kathmandu Medical College were included and interviewed. A case was defined as a woman who sought an elective medical or surgical abortion. A control was defined as a woman who sought medical care at the outpatient department or had already been admitted to the ward for reasons other than elective abortion. A questionnaire developed for the study - dealing with different demographic characteristics as well as knowledge about and attitudes toward contraceptives - was filled out based on the interview. Results: A total of 153 women were included: 64 women seeking an abortion and 89 controls. Women seeking an abortion had been pregnant more times than the control group and were more likely to have been informed about contraceptives. Women with higher education were less likely to seek an abortion than women with lower education. There was no significant difference in knowledge about and attitudes toward contraceptives between cases and controls. The women considered highest possible effectiveness to be the most important feature when deciding on a birth control method. Conclusion: Women seeking abortion in Kathmandu had shorter education and a history of more pregnancies and deliveries than women in the control group. Education and counseling on sex and reproduction as well as on contraceptive methods probably need to be improved in Nepal to avoid unwanted pregnancies. Attitudes about contraceptives need to be further investigated to develop better and more effective methods to educate women about family planning in order to increase reproductive health. © 2014 Berin et al.

- Objective Most women experience vasomotor symptoms (VMS) around menopause that may affect quality of life negatively. Effective pharmacological treatment exists but is not recommended for all women, and there is a demand for alternatives to reduce symptoms and improve quality of life. The objective of this study was to investigate the effect of a resistance training intervention on health-related quality of life (HRQoL) in postmenopausal women with VMS. Methods This open randomized controlled trial included 65 postmenopausal women >45 years old with daily VMS. The participants were randomized to 15 weeks of resistance training three times per week or an untreated control group. The Womens Health Questionnaire (WHQ) and Short Form Health Survey (SF-36) were used to assess HRQoL at baseline and after 15 weeks. Results The resistance training group improved compared to the control group in the WHQ domains of VMS (p = 0.002), sleep problems (p = 0.003) and menstrual symptoms (p = 0.01) from baseline to post intervention. No significant between-group differences were found in SF-36 summary scores, or in any of the domains. Conclusion In postmenopausal women with moderate to severe VMS, resistance training three times per week for 15 weeks improved menopause-specific HRQoL.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Resistance training may be an effective intervention to improve menopausal symptoms and increase womens quality of life. However, most postmenopausal women do not perform regular resistance training. The purpose of this study was to explore postmenopausal womens experiences of participation in a resistance-training intervention to find barriers and motivators for the training. Methods: Fifteen postmenopausal women with low physical activity, who participated in a randomized controlled trial evaluating the effect of a resistance-training program on vasomotor symptoms and health-related outcomes, were consecutively recruited to this qualitative study. After completion of the 15-week resistance-training program, they took part in individual semi-structured interviews, followed by a telephone interview 1 year later. All interviews were transcribed verbatim and thematic analysis was used to analyse the data. Results: The analysis generated three themes that were involved at different time points. These were: "Trigger-Hopes of symptom relief", "An evolving motivation as a driving force for change" and "Finding new triggers". Accountability, and continuous professional and emotional support, were factors that fueled the womens motivation to perform regular resistance training during the study. Resistance training improved general well-being and most women experienced improvement in vasomotor symptoms. The womens motivation changed from being driven by a wish to improve bothersome symptoms, into a wish to achieve feelings of well-being and enjoyment. The change was seen regardless of effects of the intervention on vasomotor symptoms. Conclusion: This first qualitative evaluation of physical exercise as an intervention to treat vasomotor symptoms in postmenopausal women, found that the symptoms acted as a motivational trigger to initiate resistance training in low-active women. The motivation to exercise changed during the intervention from a wish to ameliorate symptoms into something the women did for enjoyment and well-being in general. This change in motivating factors may have contributed to a behavior change since all participants had increased their physical activity after 1 year regardless of effects on VMS.

Resistance Training and Physical Activity in Postmenopausal Women : Effects on Vasomotor Symptoms, Quality of Life and Microcirculation
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background Menopause is a physiological event, but is associated with bothersome symptoms as well as physical changes that affect women’s health. About 75 % of women experience vasomotor symptoms (hot flushes and night sweats) related to menopause that often reduce quality of life. The vasomotor symptoms may be attributed to dysfunctional temperature regulation centrally in the hypothalamus and peripherally in the skin’s circulation. The most effective treatment for vasomotor symptoms is menopausal hormone therapy, but not all women are able to, or want to, use it. In addition to the impact on quality of life, studies have associated vasomotor symptoms and menopause with macrovascular endothelial dysfunction. Previous studies on the association of these factors with the skin’s microcirculatory function are small and few. Observational studies have associated physical activity and exercise with less vasomotor symptoms, but the evidence from intervention trials is of low quality and the results are ambiguous. Physical activity has established general health effects, and could potentially decrease vasomotor symptoms by effects on endogenous opioids centrally, and by more efficient thermoregulation peripherally. The aim of this thesis was to investigate the effect of resistance training on vasomotor symptoms and health-related quality of life in postmenopausal women, and to explore the women’s experiences of the training to find barriers and facilitators. We also aimed to investigate whether the skin’s microcirculatory function differed between women regarding menopausal status, vasomotor symptoms, menopausal hormone therapy, and physical activity. Material and methods The first study was an open randomized controlled trial including 65 postmenopausal women with moderate to severe vasomotor symptoms and low physical activity levels. We randomized the women to 15 weeks of resistance training (intervention) or unchanged physical activity (control). The participants registered vasomotor symptoms daily in a diary, and answered health-related quality of life questionnaires at baseline and at 15 weeks. The first 15 women to finish the intervention were recruited to a qualitative study. The women’s experiences of the resistance training intervention were explored in individual interviews after the intervention period, and all were followed-up with telephone interviews after one year. The third study was cross-sectional, including 1148 women from Linköping, 50-64 years old, who participated in the Swedish CArdioPulmonary bioImage Study (SCAPIS). These women answered a questionnaire about menopausal status, vasomotor symptoms and menopausal hormone therapy use, and wore accelerometers for seven days to assess physical activity. The skin’s microcirculation was assessed at rest and during post-occlusive reactive hyperemia. Results Moderate to severe vasomotor symptoms per 24 hours decreased significantly more in the group of women randomized to resistance training compared with the control group (mean difference -2.7, 95% CI -4.2 to -1.3). The resistance training group improved in domains of menopause-specific health-related quality of life compared with the control group but there was little impact on generic health-related quality of life. In the qualitative study we found that the vasomotor symptoms acted as a “trigger” for the women to become motivated to exercise. Their motivation then evolved from being driven by hopes of symptom relief into being driven by a wish for general well-being, which was still a driving force after one year. Microvascular function did not differ between postmenopausal and premenopausal women, or between women with or without vasomotor symptoms or menopausal hormone therapy. Women with higher levels of objectively measured and self-reported physical activity had a better reactivity of the skin’s microcirculation. The differences remained significant after adjusting for BMI, smoking, hypertension, diabetes, and education. Conclusions Resistance training could be effective for decreasing vasomotor symptoms and improving some aspects of health-related quality of life in motivated postmenopausal women. The vasomotor symptoms themselves spurred motivation to exercise, indicating they present an opportunity to increase physical activity. When a woman seeks medical advice for vasomotor symptoms, this could be a chance for health care professionals to help her initiate or increase exercise. Women who performed more physical activity and exercise had better skin microvascular function, but no association with VMS was found. Future studies are needed to investigate what type and dose of exercise is the most effective to reduce vasomotor symptoms and whether there is a way to predict for whom exercise will or will not be an effective intervention.

- Objectives: To investigate the effect of 15 weeks of resistance training on the frequency of moderate to severe hot flushes in postmenopausal women. Study design: Postmenopausal women with at least 4 moderate or severe hot flushes or night sweats per day day were randomized to a 15-week resistance training intervention or unchanged physical activity. Participants did not exercise regularly at baseline and had not used any therapy for hot flushes two months prior to study entry. The resistance training was performed three times per week and the program contained 8 exercises performed with 8-12 repetitions in 2 sets. Loads were set individually from eight-repetition maximum-strength tests and increased progressively. Main outcome measures: The primary outcome was change in mean moderate or severe hot flushes per day from baseline to week 15, assessed with symptom diaries. Secondary outcomes included change in hot flush score and time spent on physical activity. Results: Between November 19, 2013, and October 26, 2016, 65 women were enrolled; 58 completed the trial and were included in the analyses. The mean age was 55 and the mean number of moderate or severe hot flushes per day at baseline was 7.1; there were no baseline differences between groups. The frequency of hot flushes decreased more in the intervention group than in the control group (mean difference -2.7, 95% CI -4.2 to -1.3). The mean percentage change was -43.6% (-56.0 to -31.3) in the intervention group and -2.0% (16.4-12.4) in the control group. Conclusion: A 15-week resistance-training program decreased the frequency of moderate and severe hot flushes among postmenopausal women and could be an effective and safe treatment option to alleviate vasomotor symptoms.

- Objectives: Hot flushes and night sweats affect 75% of all women after menopause and is a common reason for decreased quality of life in mid-aged women. Hormone therapy is effective in ameliorating symptoms but cannot be used by all women due to contraindications and side effects. Engagement in regular exercise is associated with fewer hot flushes in observational studies, but aerobic exercise has not proven effective in randomized controlled trials. It remains to be determined whether resistance training is effective in reducing hot flushes and improves quality of life in symptomatic postmenopausal women. The aim of this study is to investigate the effect of standardized resistance training on hot flushes and other health parameters in postmenopausal women. Study design: This is an open, parallel-group, randomized controlled intervention study conducted in Linkoping, Sweden. Sixty symptomatic and sedentary postmenopausal women with a mean of at least four moderate to severe hot flushes per day or 28 per week will be randomized to an exercise intervention or unchanged physical activity (control group). The intervention consists of 15 weeks of standardized resistance training performed three times a week under supervision of a physiotherapist. Main outcome measures: The primary outcome is hot flush frequency assessed by self-reported hot flush diaries, and the difference in change from baseline to week 15 will be compared between the intervention group and the control group. Conclusion: The intention is that this trial will contribute to the evidence base regarding effective treatment for hot flushes. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

- Background: Vasomotor symptoms (VMS) are common around menopause. Menopausal hormone therapy is the most effective treatment for VMS. Physical exercise has been proposed as an alternative treatment since physically active women have previously been found to experience fewer VMS than inactive women. In our randomised controlled trial on resistance training to treat VMS, sympoms were reduced by 50% in the intervention group compared with the control group.Objectives: To propose a mechanism to explain how resistance training reduced VMS and to assess if luteinizing hormone (LH) and follicle stimulating hormone (FSH) were affected in accordance with the proposed mechanism.Trial design and methods: A substudy of a randomized controlled trial on 65 postmenopausal women with VMS and low physical activity who were randomised to 15 weeks of resistance training three times per week (n = 33) or to a control group (n = 32). To be regarded compliant to the intervention we predecided a mean of two training sessions per week. The daily number of VMS were registered before and during the 15 weeks. Blood samples were drawn for analysis of LH and FSH at baseline and after 15 weeks.Results: LH decreased significantly in the compliant intervention group compared with the control group (-4.0±10.6 versus 2.9±9.0, p = 0.028 with Mann-Whitney U test). FSH also decreased in the compliant intervention group compared with the control group, however not enough to reach statistical significance (-3.5±16.3 versus 3.2±18.2, p = 0.063 with Mann-Whitney U test). As previously published the number of hot flushes decreased significantly more in the intervention group than in the control group but there was no association between change in LH or FSH and in number of VMS.Conclusions: We propose that endogenous opiods such as β-endorphin or dynorphin produced during resistance training decreased VMS by stimulating KNDγ-neurons to release neurokinin B to the hypothalamic thermoregulatory centre. Through effects on KNDγ-neurons, β-endorphin could also inhibit GnRH and thereby decrease the production of LH and FSH. The significanty decreased LH in the compliant intervention group compared with the control group was in accordance with the proposed mechanism.

- The objective of this study was to determine if 15 weeks of resistance training (RT) can alter the levels of blood lipids, body iron status, and oxidative stress in postmenopausal women with vasomotor symptoms. Postmenopausal women enrolled in a randomised controlled trial were allocated to either a sedentary control group (n=29) or a RT group (n=26). Blood samples were taken at week-0 and week-15 for all participants. Blood lipids and iron status were measured via routine clinical analyses. Immunoassays were used to measure oxidative stress markers. The RT group, with good compliance, was associated with significant reductions in ferritin, total cholesterol, low-density lipoprotein, and non-high-density lipoprotein cholesterol. Moreover, ferritin was positively correlated with atherogenic lipids while negatively correlated with high-density lipoprotein in RT women. This occurred without alterations in serum iron, transferrin, transferrin-saturation, C-reactive protein and oxidative stress markers. No differences were found in control women. This study suggests that RT in postmenopausal women both reduces levels of ferritin and counteracts atherogenic lipid profiles independent of an apparent oxidative mechanism. RT may be a beneficial intervention in postmenopausal women via an interaction between ferritin and lipids; however, further investigation in a larger cohort is essential.

- Physical inactivity and the onset of menopause increase the risk of cardiovascular disease amongst postmenopausal women. We aim to investigate the effect of resistance training (RT) on plasma levels of selected cytokines, adipokines, myokines, and sex hormones in postmenopausal women with vasomotor symptoms. This was a sub-study of a randomised controlled trial investigating the effects of RT on vasomotor symptoms in postmenopausal women. Women were randomised to join a 15-week RT program (n=26) or remain sedentary as control (n=29). Venous blood samples were taken at week-0 and week-15 for all participants. Enzyme-linked immunosorbent assays and multiple bead assays were used to measure cytokines, adipokines, myokines, and sex hormones in plasma. Plasma measurements of 16 of 33 analytes were within detectable limits. After adjusting for good compliance in the RT group (58% of RT participants), after 15 weeks, significantly lower plasma levels of adiponectin (p<0.001), lipocalin-2 (p<0.01) and resistin (p=0.04) were found. Comparing control and RT women, using change-over-time values, significant increases in median testosterone and sex hormone binding globulin levels were seen in RT women. RT intervention lowers the levels of adipokines, particularly adiponectin, in postmenopausal women with vasomotor symptoms. These results were secondary outcomes of a clinical trial, and further investigations in a larger cohort are essential with the additional control of diet control and body composition analyses. Nevertheless, our study shows RT may be a beneficial intervention in reducing inflammation amongst postmenopausal women.
