Abstract STUDY QUESTION Do diet, physical activity and contraceptive use change after receiving a diagnosis of polycystic ovary syndrome (PCOS)? SUMMARY ANSWER Using longitudinal data 12 months apart, young women newly diagnosed with PCOS were more likely to stop using contraception but did not change their physical activity or vegetable intake. WHAT IS KNOWN ALREADY Diagnostic criteria for PCOS have widened to capture more women, despite limited evidence of the benefits and harms. Possible benefits of a PCOS diagnosis are that it may help women with family planning and motivate them to implement healthy lifestyle changes to reduce the reproductive, metabolic and cardiovascular risks associated with PCOS. However, there are no empirical studies investigating how women respond to a diagnosis of PCOS with respect to their health behaviour, and longitudinal population-based studies are lacking. STUDY DESIGN, SIZE, DURATION This is a longitudinal analysis of two waves of data collected 12 months apart from the cohort born 1989–1995 in the Australian Longitudinal Survey on Women’s Health, a population-based cohort study. Women in this cohort were first surveyed in 2012-2013, aged 18-23 years. PARTICIPANTS/MATERIALS, SETTING, METHODS Women who responded to the 2014 survey (aged 19–24, n = 11 344) and 2015 survey (aged 20–25, n = 8961) were included. Using logistic regression, multinomial logistic regression and linear regression, change in vegetable intake, physical activity and contraceptive use were compared for women newly diagnosed with PCOS to women not reporting a diagnosis of PCOS. Changes in psychological distress and BMI were also examined. MAIN RESULTS AND THE ROLE OF CHANCE Young women reporting a new diagnosis of PCOS were no more likely to increase their vegetable intake or physical activity than women not reporting a PCOS diagnosis. Women newly diagnosed with PCOS were 3.4 times more likely to stop using contraception during the 12-month study period than women without PCOS (14% versus 4%, 95% CI = 2.3 to 5.1, P < 0.001). This difference remained significant after controlling for demographics, chronic conditions associated with PCOS, endometriosis, BMI and psychological distress (P < 0.001). LIMITATIONS, REASONS FOR CAUTION All data was self-reported including PCOS diagnosis, assessment of diet quality was limited to vegetable intake only. The exact timing of diagnosis within the 12-month period and whether the women intended to conceive are unknown. The number of women reporting a new diagnosis of PCOS was also relatively small. WIDER IMPLICATIONS OF THE FINDINGS These findings suggest that a diagnosis of PCOS may not produce short-term benefits by way of improving health behaviour. The observed reduction in contraception use suggests some women may be at increased risk of unplanned pregnancies, highlighting the importance of counselling about contraceptive needs. Both potential benefits and harms must be considered when determining the appropriateness of a PCOS diagnosis.

Dietary intake potentially modifies the prevalence or severity of asthma. The prevalence of asthma is higher in women with polycystic ovary syndrome (PCOS); it is not known if diet confounds or modifies the association between asthma and PCOS. The aims of this study were: (i) To determine if the association of PCOS and asthma is independent of dietary pattern and (ii) to determine if dietary pattern modifies the association between PCOS and asthma. Women in this study were from the Australian Longitudinal Study on Women’s Health (ALSWH) cohort born between 1973 to 1978 and aged 18 to 23 years (n = 7382). Logistic regression was used to assess the association between PCOS and asthma, adjusting for the following: (i) Potential confounders identified a priori and (ii) dietary patterns (z-score) identified by principle component analysis. In the adjusted analysis, women with PCOS were more likely to have asthma than the women without PCOS (OR 1.35 and 95% CI, 1.02 and 1.78). This relationship was not altered by further adjustment for dietary patterns (non-core food, meats and takeaway, or Mediterranean-style pattern). In the interaction analysis, only the women consuming less than the median intake of non-core foods (i.e., lower intake of discretionary or unhealthy foods) and with PCOS were more likely to have asthma (OR 1.91 and 95% CI, 1.29 and 2.82). Dietary intake did not confound the relationship between PCOS and asthma. Other mechanistic pathways are likely responsible for the asthma and PCOS association, and further studies assessing factors such as oral contraceptive use and sex steroid hormones warrant investigation.

AbstractObjective:This study investigated young women's perceptions of the feasibility of physical activity and healthy eating behaviours, and how these vary by socio-economic status, domestic characteristics and weight status.Design:This population-based study used a mailed questionnaire to investigate perceptions of the feasibility of commonly recommended healthy eating and physical activity behaviours among a sample of young women. The feasibility of 29 physical activity behaviours (e.g. relating to frequency, intensity, duration, domain/setting) and 15 healthy eating behaviours (e.g. relating to location/setting, fruit and vegetable intake, fat/sugar intake) was assessed. Height, weight and sociodemographic details were also obtained.Setting:Nation-wide community-based survey.Subjects:A total of 445 women aged 18–32 years selected randomly from the Australian electoral roll.Results:Most women reported that they either were already engaged in many of the healthy eating behaviours or saw these as highly feasible. Many physical activity behaviours, on the other hand, were perceived as less feasible, particularly among women with children and women who were overweight.Conclusions:Health promotion messages and strategies aimed at increasing physical activity and healthy eating are unlikely to succeed unless they take into account perceptions that these behaviours are not feasible. For young women, this may involve promoting more time-effective, flexible ways of achieving recommended physical activity. Messages specifically targeted to women with children, and women who are overweight, are required.

Abstract Background National guidelines promote physical activity to prevent cardiovascular disease (CVD), yet no randomized controlled trial has tested whether physical activity reduces CVD. Methods The Women’s Health Initiative (WHI) Strong and Healthy (WHISH) pragmatic trial used a randomized consent design to assign women for whom cardiovascular outcomes were available through WHI data collection (N = 18 985) or linkage to the Centers for Medicare and Medicaid Services (N30 346), to a physical activity intervention or “usual activity” comparison, stratified by ages 68–99 years (in tertiles), U.S. geographic region, and outcomes data source. Women assigned to the intervention could “opt out” after receiving initial physical activity materials. Intervention materials applied evidence-based behavioral science principles to promote current national recommendations for older Americans. The intervention was adapted to participant input regarding preferences, resources, barriers, and motivational drivers and was targeted for 3 categories of women at lower, middle, or higher levels of self-reported physical functioning and physical activity. Physical activity was assessed in both arms through annual questionnaires. The primary outcome is major cardiovascular events, specifically myocardial infarction, stroke, or CVD death; primary safety outcomes are hip fracture and non-CVD death. The trial is monitored annually by an independent Data Safety and Monitoring Board. Final analyses will be based on intention to treat in all randomized participants, regardless of intervention engagement. Results The 49 331 randomized participants had a mean baseline age of 79.7 years; 84.3% were White, 9.2% Black, 3.3% Hispanic, 1.9% Asian/Pacific Islander, 0.3% Native American, and 1% were of unknown race/ethnicity. The mean baseline RAND-36 physical function score was 71.6 (± 25.2 SD). There were no differences between Intervention (N = 24 657) and Control (N = 24 674) at baseline for age, race/ethnicity, current smoking (2.5%), use of blood pressure or lipid-lowering medications, body mass index, physical function, physical activity, or prior CVD (10.1%). Conclusion The WHISH trial is rigorously testing whether a physical activity intervention reduces major CV events in a large, diverse cohort of older women.

Abstract Introduction Regular exercise is known to decrease the risk of dementia. There is a paucity of information about the impact of the change of exercise habit on cardiovascular outcomes after a new diagnosis of atrial fibrillation (AF). We aimed to investigate whether regular exercise is associated with the risk of developing dementia in patients with AF. Methods Using the Korean National Health Insurance Service database, we enrolled patients with newly diagnosed AF who had undergone health screening between 2010 and 2016. The study population was divided into four groups based on the consistency of regular exercise before and after AF diagnosis: (1) persistent non-exerciser, (2) exercise starter, (3) exercise quitter, and (4) exercise maintainer. We investigated the association between exercise and the risk of dementia. Results A total of 126,555 patients were included (mean age 62.7 years, male 62.0%, and mean CHA2DS2-VASc Score 2.7). During a median follow-up duration of 3.0 years, 5,943 patients were newly diagnosed as dementia (1.57 per 100 person-years). Among patients with incident dementia, 4,410 patients had Alzheimer's dementia and 951 patients had vascular dementia (1.16 and 0.25 per 100 person-years, respectively). Persistent non-exerciser, exercise starter, quitter, and maintainer groups were 65.1%, 12.8%, 12.7%, and 9.4%, respectively. After multivariable adjustment, we found that exercise was associated with a lower risk of developing overall dementia. When compared to persistent non-exerciser, exercise starter and maintainer showed reduced risk of developing dementia (hazard ratio [HR] 0.80, 95% confidence interval [95% CI] 0.73–0.88 and HR 0.63, 95% CI 0.54–0.73, respectively, all p-value <0.0001), but exercise quitter showed no significant risk reduction (HR 0.95, 95% CI 0.88–1.03, Figure). Alzheimer's dementia showed consistent results: a 20% lower risk with exercise starter, and a 37% lower risk with exercise maintainer. Change of exercise habit, however, did not affect the risk of vascular dementia (all, p-value >0.05, Figure). Conclusions Regular exercise showed a lower risk of dementia in patients with new-onset AF. Starting exercise even after the diagnosis of AF was beneficial to patients who had little physical activity previously. These findings may support physicians to recommend that AF patients should start exercise or keep their physical activity to reduce the risk of dementia.

Background: It is unclear whether exercise would reduce dementia in patients with a new diagnosis of atrial fibrillation (AF). Therefore, we aimed to evaluate the association between the change in physical activity (PA) before and after new-onset AF and the risk of incident dementia. Methods: Using the Korean National Health Insurance Service database, we enrolled a total of 126,555 patients with newly diagnosed AF between 2010 and 2016, who underwent health examinations within two years before and after their diagnosis of AF. The patients were divided into four groups: persistent non-exercisers, exercise starters, exercise quitters, and exercise maintainers. Results: Based on a total of 396,503 person-years of follow-up, 5943 patients were diagnosed with dementia. Compared to persistent non-exercisers, exercise starters (adjusted hazard ratio (aHR) 0.87; 95% confidence interval (CI) 0.81–0.94), and exercise maintainers (aHR 0.66; 95% CI 0.61–0.72) showed a lower risk of incident dementia; however, the risk was similar in exercise quitters (aHR 0.98; 95% CI 0.92–1.05) (p-trend < 0.001). There was a J-shaped relationship between the dose of exercise and the risk of dementia, with the risk reduction maximized at 5–6 times per week of moderate-to-vigorous PA among exercise starters. Conclusion: Patients who initiated or continued regular exercise after diagnosis of AF were associated with a lower risk of dementia than persistent non-exercisers, with no risk reduction associated with exercise cessation. Our findings may provide evidence for the benefit of exercise prescription to patients with new-onset AF to prevent incident dementia regardless of their current exercise status.
