- Objectives. There is limited knowledge of atrial fibrillation (AF) incidence among the very old. Data from longitudinal cohort studies may give us a better insight. The aim of the study was to investigate the incidence rate and prevalence of AF, as well as the impact of AF on mortality, in the general population, from 70 to 100 years of age. Design. This was a population-based prospective cohort study where three representative samples of 70-year-old men and women (n = 2,629) from the Gerontological and Geriatric Populations Studies in Gothenburg (H-70) were included between 1971 and 1982. The participants were examined at age 70 years and were re-examined repeatedly until 100 years of age. AF was diagnosed according to a 12-lead electrocardiogram (ECG) recording at baseline and follow-up examinations, from the Swedish National Patient Register (NPR), or from the Cause of Death Register. Results. The cumulative incidence of AF from 70 to 100 years of age was 65.6% for men and 52.8% for women. Mortality was significantly higher in participants with AF compared with those without, rate ratio (RR) 1.92 (95% CI 1.73-2.14). In a subgroup analysis comprising only participants with AF diagnosed by ECG at screening, the RR for death was 1.29 (95% C.I: 1.03-1.63). Conclusions. Among persons surviving to age 70, the cumulative incidence of AF was over 50% during follow-up. Mortality rate was twice as high in participants with AF compared to participants without AF. Among participants with AF first recorded at a screening examination, the increased risk was only 29%.

- Objective To assess stroke incidence over 44 years and association with risk factors. To study total stroke incidence at 60-82 years of age and risk factors. Design Prospective population study. Setting Gothenburg, Sweden, with similar to 450,000 inhabitants. Subjects A representative sample of a general population of women (1462 in total) in 5 age strata aged 38-60 years in 1968-1969 (the Population Study of Women in Gothenburg, PSWG) were followed up to the ages of 82-104 years in 2012. Further, analysis was also performed for the age interval 60-82 years. Main outcome measures Incidence of total stroke (TS), ischaemic (IS), haemorrhagic (HS), non-specified (NS) and fatal (FS) strokes and association with baseline classic risk factors (such as hypertension, atrial fibrillation, low physical activity, diabetes, high waist-hip-ratio, hyperlipidaemia, smoking), low education, mental stress, pre-eclampsia and oral health as expressed by loss of teeth and bone score. Blood pressure in levels 1-3 according to modern guidelines. Associations with atrial fibrillation, diabetes and myocardial infarction shown in survival analyses. The five cohorts contributed to risk time data concerning associations with TS in the 60-82 age interval from the examination performed when they were 60. Results Three hundred and thirty-seven (23%) women had a first-ever stroke, 64 (19%) fatal. TS was associated with physical inactivity, high triglycerides and low education in multivariable analysis. The main sub-type IS was associated with systolic blood pressure, physical inactivity and low education. Pre-eclampsia showed association with IS only in the univariable analysis. FS was associated with systolic blood pressure and smoking. During 60-82 years of age, having <20 teeth (HR 1.74, CI 1.25-2.42), diabetes (HR 2.28 CI 1.09-4.76), WHR (HR 1.29 per 0.1 units CI 1.01-1.63), systolic blood pressure (HR 1.11 per 10 units CI 1.04-1.18) and smoking (HR 1.57, CI 1.14-2.16), were associated with TS in the combined five cohorts. Conclusions Several classic risk factors showed independent associations with stroke. Vulnerability factors as low education and oral health, reflected by loss of teeth, also showed association with stroke. All these factors are possible to target in primary care preventive interventions.

Tidskriftsartikel (refereegranskat)abstract
- Fatty acids are involved in bone development but knowledge in children is limited. The aim of this study was to investigate bone mass and mineral density in healthy preschool children in relation to fatty acids.In 111 healthy 4-yrs-old children (20% overweight) bone was analysed by dual X-ray absorptiometry and serum phospholipid fatty acid by gas chromatography. Fat intake was calculated from 7 days self-reported dietary records and food frequency questionnaire.Total bone mass content (BMC) and mineral density (BMD) differed by sex in normal weight, but not in overweight children showing generally higher bone mass density than children with normal weight. Linoleic acid intake was strongly correlated to BMC and femoral BMD in normal weight children. Serum concentration of docosahexaenoic acid correlated positively to BMD in all children (p=0.01), but linoleic and arachidonic acids, and monounsaturated fatty acids showed diverging associations with bone in normal weight and overweight children.Serum phospholipid DHA was associated with bone density. Other fatty acids associations to bone sites differed in overweight children, analogue to the pattern in healthy 8-yrs-old.The finding need to be confirmed longitudinally and in a larger group of overweight individuals.

- Several risk factors for loss of height with increasing age have been identified.To investigate if mandibular bone structure predicts future height loss in middle-aged and elderly Swedish women.Prospective cohort study with longitudinally measured heights, radiographical assessments of the cortical bone using Klemetti's Index (normal, moderate or severely eroded cortex) and classification of the trabecular bone using an index proposed by Lindh et al (sparse, mixed or dense trabeculation). No intervention was performed.Gothenburg, Sweden.A population-based sample of 937 Swedish women born in 1914, 1922 and 1930 was recruited. At the baseline examination, the ages were 38, 46 and 54 years. All had undergone a dental examination with panoramic radiographs of the mandible, and a general examination including height measurements on at least two occasions.Height loss was calculated over three periods 12-13years (1968-1980, 1980-1992, 1992-2005).Mean annual height loss measures were 0.075cm/year, 0.08cm/year and 0.18cm/year over the three observation intervals, corresponding to absolute decreases of 0.9cm, 1.0cm and 2.4cm. Cortical erosion in 1968, 1980 and 1992 significantly predicted height loss 12 years later. Sparse trabeculation in 1968, 1980 and 1992 also predicted significant shrinkage over 12 or 13 years. Multivariable regression analyses adjusting for baseline covariates such as height, birth year, physical activity, smoking, body mass index and education yielded consistent findings except for cortical erosion 1968-1980.Mandibular bone structure characteristics such as severe cortical erosion and sparse trabeculation may serve as early risk factors for height loss. Since most individuals visit their dentist at least every 2years and radiographs are taken, a collaboration between dentists and physicians may open opportunities for predicting future risk of height loss.

- Longitudinal assessment is useful for tracking patterns of alcohol use over time. Non-response is a common feature of longitudinal design and can bias estimates of alcohol use if there exist systematic differences between respondents and non-respondents. We investigated whether alcohol use, health status, and sociodemographic characteristics were determinants of non-response in a longitudinal cohort of women in the general population. We used data from a stratified, random sample of 479 women born in 1925, 1935, 1945, 1955, 1965, and 829 women born in 1970 and 1975, who were initially selected as participants in the Women and Alcohol in Gothenburg project. Results from multivariable logistic regression revealed that problematic alcohol use, depression, poor self-rated physical health, and basic education were associated with increased odds of non-response among women born in 1925, 1935, 1945, 1955, and 1965. Among women born between 1970 and 1975, older age and being unmarried increased the odds of non-response at follow-up. Surprisingly, problematic alcohol use and poor health were not associated with non-response in these younger birth cohorts. This study finding suggests that approaches to improve future survey response rates need to consider factors of greatest relevance to birth year and age.

- Objective The aim of this study was to examine if there are any differences in the prevalence of daily hot flashes in 50-year-old women in a longitudinal perspective (from 1968 to 2017). Methods Cohort comparisons of four population-based samples of 50-year-old women born in 1918, 1930 (earlier-born cohorts), 1954, and 1966 (later-born cohorts) from the Prospective Population Study of Women in Gothenburg examined in 1968-1969, 1980-1981, 2004-2005, and 2016-2017. Questions about frequency of hot flashes have been formulated in the same way throughout all follow-up examinations. Changes between four generations of 50-year-old women were studied. Results In the unadjusted model, we found an increased prevalence of daily hot flashes in 50-year-old women born in 1954 and 1966 compared with 50-year-old women born in 1918 and 1930 (odds ratio, 1.74; 95% confidence interval, 1.37-2.22). When considering potential predictors for daily hot flashes (smoking, perceived level of high stress, BMI, waist-to-hip ratio, hormone therapy, and hormonal contraceptives) in the adjusted model, there was a notable difference; odds ratio increases from 1.74 to 1.92 (95% confidence interval, 1.46-2.52). Smoking frequency was substantially lower in the later-born cohorts, 39% compared with 17%. Conclusions In this prospective longitudinal study of 50-year-old women, we found nearly twice as high odds of reporting daily hot flashes in the later-born women compared with earlier-born. When controlling for potential predictors, there was still an obvious difference, which cannot be explained in our study. These findings have not earlier been described, and there is a need for further longitudinal population studies investigating the prevalence of hot flashes over time. Moreover, additional research is required exploring the underlying mechanism of hot flashes, as well as studies that take into account potential risk factors in the environment and societal development over time, that is, impacts of endocrine-disrupting chemicals changes in lifestyle, environmental, and dietary factors, as well as working conditions.

- Death of a spouse is associated with poorer physical and mental health. We followed all married individuals, born from 1902 to 1942, during the period from 1987 to 2002, and found that widows and widowers had higher risk for hip fracture, compared with still married women and men. Introduction Spousal bereavement can lead to poorer physical and mental health. We aimed to determine whether married women and men had an elevated risk of hip fracture after death of a spouse. Methods In a retrospective cohort study, we followed all Swedish married individuals aged 60 to 100 years (n = 1,783,035), from 1987 to 2002. Data are presented as mean with 95% confidence interval (CI). Results During the follow-up period, 21,305 hip fractures among widows and 6538 hip fractures among widowers were noted. The hazard ratio (HR) for hip fracture in widows compared with married women was 1.34 (95% CI 1.31 to 1.37) and for widowers compared with married men 1.32 (95% CI 1.29 to 1.35). The HR for hip fracture in the first 6 months after death of a spouse was in widows compared with married women 1.62 (95% CI 1.53 to 1.71) and in widowers compared with married men 1.84 (95% CI 1.68 to 2.03). The elevated risk was especially prominent in young widowers in the age range 60-69 years. During the first 6 months they showed a HR of 2.76 (95% CI 1.66 to 4.58) for a hip fractvure compared with age matched married men. Widows aged 60-69 years showed a HR of 1.59 (95% CI 1.26 to 1.99) compared with age matched married women. Conclusion Our observation of a higher hip fracture risk in both genders in connection with the death of a spouse indicates a possible effect of bereavement on frailty.

- We studied the risk for hip fracture before and after total knee replacement (TKR) in the entire population in Sweden. Women and men had a low risk for hip fracture before TKR but an increased risk the first year after TKR. Purpose It is known that osteoarthritis is associated with high bone mass. We therefore studied the risk of hip fracture before and after total knee replacement (TKR), risk of different hip fracture types, and risk subdivided in genders and age groups. Methods We followed the total Swedish population born between 1902 and 1952 (n = 4,258,934) during the period 1987-2002 and identified all patients with TKR due to primary OA (n = 39,291), and all patients with hip fracture (n = 195,860) in the Swedish National Inpatient Register. The risk time analyses were based on Poisson regression models. Results The hazard ratio (HR) for hip fracture the last year before TKR was 0.86 (95% CI 0.74 to 1.00) and the first year after 1.26 (95% CI 1.11 to 1.42) compared to individuals without TKR. The HR for femoral neck fracture 0-10 years after TKR was 0.95 (95% CI 0.89 to 1.01) and for trochanteric fracture was 1.13 (95% CI 1.06 to 1.21). The HR for hip fracture in the age group 50-74 was 1.28 (95% CI 1.14 to 1.43) and in the age group 75-90 years was 0.99 (95% CI 0.94 to 1.04) 0-10 years after TKR, compared to individuals without TKR. Conclusion Individuals had a low risk for hip fracture before TKR but an increased risk the first year after TKR. The risk in individuals below age 75 years and for trochanteric fractures was increased after TKR. Possible explanations include changed knee kinematics after a TKR, physical activity level, fall risk, and other unknown factors.

- This study aimed to examine the association between anxiety disorders and/or major depression disorder (ADs/MDD) and all-cause mortality in a 50-year perspective and to examine specific risk and health factors that may influence such an association.Observational population study, 1968-2019.The Population Study of Women in Gothenburg, Sweden (PSWG).In 1968-1969, 899 (out of 1462) women from PSWG were selected according to date of birth for a psychiatric investigation, including diagnostic evaluation. Eight hundred (89%) were accepted. Twenty-two women were excluded. Of the 778 included, 135 participants (17.4 %) had solely ADs, 32 (4.1%) had solely MDD and 25 (3.2%) had comorbid AD/MDD.Associations between ADs, MDD, comorbid AD/MDD and all-cause mortality with adjustments for potential confounding factors. Differences between the groups concerning health and risk factors and their association with mortality.In a fully adjusted model, ADs were non-significantly associated with all-cause mortality (HR 1.17, 95%CI 0.98 to 1.41). When examining age during risk time as separate intervals, a significant association between mortality and AD was seen in the group of participants who died at the age of 65-80 years (HR 1.70, 95%CI 1.26 to 2.29). In the younger or older age interval, the association did not reach significance at the 95% level of confidence. Among confounding factors, smoking and physical activity were the strongest contributors. The association between smoking and mortality tended to be further increased in the group with ADs versus the group without such disorders (HR 2.10, 95%CI 1.60 to 2.75 and HR 1.82, 95%CI 1.56 to 2.12, respectively).This study suggests potential links between ADs, age and mortality among women with 50 years of follow-up, but does not provide definitive conclusions due to the borderline significance of the results.

- Women's lives have dramatically changed in recent decades as evidenced by trends in educational attainment, employment outside the home, income, and other socioeconomic factors. Self-reported health in 18-70year old women has been reported to be significantly lower than in men. In Sweden, the 2005 National Public Health Report showed that stressful work environments have become more common, especially for women. The purpose of the study was to monitor trends in well-being and perceived mental stress in the populations of 38- and 50-year-old women and to examine associations with socioeconomic position (SEP).In 1980, 2004, and 2017, population-based samples of 38- and 50-year old women were recruited into the Prospective Population Study of Women in Gothenburg (PPSWG), Sweden. This population-based study included participants from selected birth cohorts to participate in health examinations, at similar ages and with similar protocols on each occasion.Birth cohort comparisons between three representative samples of 38- and 50-year-old women. Well-being (scale 1-7) and perceived mental stress (scale 1-6) based on questionnaires were the main outcomes studied in relation to time. Socioeconomic position (SEP) based on socio-occupational group, i.e. occupational and educational level combined, were examined as correlates of well-being and mental stress at different points in time.Perception of good well-being increased in generations of 50-year-old women between 1980 to 2016, but no significant time trends were seen in 38-year-old women. Perception of high mental stress increased between 1980 and 2016, for both 38-and 50-year-old women. Belonging to a low socio-occupational group was associated with lower perceived well-being in 1980 but not in 2016. Belonging to a low socio-occupational group was not associated with perceived mental stress at any examination.Contemporary women of today have generally higher perceptions of well-being but also higher mental stress regardless of belonging to low or high socio-occupational group. Associations between poor well-being and belonging to a low socio-occupational group that were observed in 1980 and 2004 were not observed in 2016. The Prospective Population Study of Women in Gothenburg, Sweden was approved by the ethics committee of University of Gothenburg (Dnr 65-80; Ö564-03; 258-16). The studies comply with the Declaration of Helsinki and informed consent has been obtained from the subjects.
