- Previous research has indicated that a variety of contextual factors are involved in the development of drinking behavior. An integrated perspective can extend our understanding of the context and circumstances in which individuals drink. In this study, a person-oriented approach, cluster analysis, was used to identify drinking context clusters in a population of 20- and 25-year-old Swedish women. A further aim was to analyze how these clusters were associated with problematic alcohol consumption (high episodic drinking (HED) and alcohol use disorder (AUD)). A total of 760 respondents were interviewed, some in 1996 and some in 2001. Self-reported effects of drinking and situational factors associated with drinking alcohol were used in the cluster analysis procedure. Logistic regression models were used to analyze the associations with problematic alcohol consumption. The results revealed four distinct clusters of drinking patterns: coping drinkers, social drinkers, controlled drinkers, and moderate drinkers. Differences between clusters concerning problematic alcohol consumption were found. HED was significantly more common among the social drinkers and alcohol use disorder was more prevalent among the coping drinkers. Age differences and to a lesser extent secular trends in drinking pattern could be observed. The findings suggest that information on drinking context can help to explain differences in patterns of risky drinking and AUD. This highlights the importance of identifying groups of individuals with potentially harmful drinking patterns, which could be the target of specific preventive actions.

- Background: The question of whether personality traits influence health has long been a focus for research and discussion. Therefore, this study was undertaken to examine possible associations between personality traits and mortality in women. Methods: A population-based sample of women aged 38, 46, 50 and 54 years at initial examination in 1968-69 was followed over the course of 40 years. At baseline, 589 women completed the Cesarec-Marke Personality Schedule (the Swedish version of the Edwards Personal Preference Schedule) and the Eysenck Personality Inventory. Associations between personality traits and mortality were tested using Cox proportional hazards models. Results: No linear associations between personality traits or factor indices and mortality were found. When comparing the lowest (Q1) and highest quartile (Q4) against the two middle quartiles (Q2 + Q3), the personality trait Succorance Q1 versus Q2 + Q3 showed hazard ratio (HR) = 1.37 (confidence interval (CI) = 1.08-1.74), and for the factor index Aggressive non-conformance, both the lowest and highest quartiles had a significantly higher risk of death compared to Q2 + Q3: for Q1 HR = 1.32 (CI = 1.03-1.68) and for Q4 HR = 1.36 (CI = 1.06-1.77). Neither Neuroticism nor Extraversion predicted total mortality. Conclusions: Personality traits did not influence long term mortality in this population sample of women followed for 40 years from mid- to late life. One explanation may be that personality in women becomes more circumscribed due to the social constraints generated by the role of women in society.

- OBJECTIVE: Personality traits are presumed to endure over time, but the literature regarding older age is sparse. Furthermore, interpretation may be hampered by the presence of dementia-related personality changes. The aim was to study stability in neuroticism and extraversion in a population sample of women who were followed from mid-life to late life. METHOD: A population-based sample of women born in 1918, 1922 or 1930 was examined with the Eysenck Personality Inventory (EPI) in 1968-1969. EPI was assessed after 37 years in 2005-2006 (n = 153). Data from an interim examination after 24 years were analysed for the subsample born in 1918 and 1922 (n = 75). Women who developed dementia at follow-up examinations were excluded from the analyses. RESULTS: Mean levels of neuroticism and extraversion were stable at both follow-ups. Rank-order and linear correlations between baseline and 37-year follow-up were moderate ranging between 0.49 and 0.69. Individual changes were observed, and only 25% of the variance in personality traits in 2005-2006 could be explained by traits in 1968-1969. CONCLUSION: Personality is stable at the population level, but there is significant individual variability. These changes could not be attributed to dementia. Research is needed to examine determinants of these changes, as well as their clinical implications.

- Neuropsychiatric Epidemiology Unit, Institute of Clinical Neurosciences, Sahlgrenska Academy at Göteborg University, SE 413 45 Göteborg, Sweden. xinxin.guo@neuro.gu.se Normal cognitive function depends on sufficient supply and efficient utilization of oxygen in the brain. Prospective studies on respiratory function and dementia are lacking. This study investigated the relationship between midlife respiratory function and incidence of dementia in a population-based sample of 1291 women followed from 1974 to 2003. Respiratory function was measured by peak expiratory flow in 1974, and forced vital capacity and forced expiratory volume in 1980. Dementia diagnoses were based on information from neuropsychiatric examinations, informant interviews, hospital records and registry data. Better respiratory function in midlife was associated with a lower late-life risk of developing dementia and Alzheimer's disease (AD). Per 1 standard deviation increase in peak expiratory flow, forced vital capacity and forced expiratory volume, hazard ratios (95% confidence intervals) for dementia were 0.77 (0.65-0.91), 0.72 (0.57-0.92) and 0.75 (0.59-0.95), respectively, and for AD 0.76 (0.62-0.94), 0.71 (0.54-0.95) and 0.74 (0.56-0.98), respectively, after adjustment for potential confounders. These data reinforce the advantages of maintaining good respiratory function in midlife, even though causation cannot be established. PMID: 16513221 [PubMed - indexed for MEDLINE]

- Background: We have shown that high mid-life central adiposity may increase the risk for dementia after 32 years. Leptin, an adipose tissue hormone, is correlated with adiposity measures and may contribute to a better etiological understanding of the relationship between high adiposity and dementia. We explored the relationship between serum leptin in mid-life and dementia, which is a late-life outcome. Methods: A longitudinal cohort study, the Prospective Population Study of Women, in Gothenburg, Sweden, includes a representative sample of 1462 women followed from mid-life ages of 38 to 60 years to late-life ages of 70 to 92 years. Women were examined in 1968, 1974, 1980, 1992, and 2000 using neuropsychiatric, anthropometric, clinical, and other measurements. Serum leptin was measured on samples collected at the 1968 baseline examination, after storage at -20 degrees C for 29 years. Cox proportional hazards regression models estimated incident dementia risk by baseline leptin. Logistic regression models related leptin levels to dementia among surviving participants 32 years later. All models were adjusted for multiple potential confounders. Results: Mid-life leptin was not related to dementia risk using Cox or logistic regression models. This was observed despite positive baseline correlations between leptin and adiposity measures, and given our previous report of high mid-life waist-to-hip ratio being related to a twofold higher dementia risk. Conclusions: Leptin is not a mid-life marker of late-life dementia risk in this population sample of Swedish women born between 1908 and 1930. (C) 2012 The Alzheimer's Association.

- Long-standing psychological distress increases the risk of dementia, especially Alzheimer's disease. The present study examines the relationship between midlife psychological distress and late-life brain atrophy and white matter lesions (WMLs), which are common findings on neuroimaging in elderly subjects. A population-based sample of 1462 women, aged 38 to 60 years, was examined in 1968, with subsequent examinations in 1974, 1980, 1992, and 2000. Computed tomography (CT) of the brain was done in 379 survivors in 2000, and of those, 344 had responded to a standardized question about psychological distress in 1968, 1974, and 1980. WMLs, cortical atrophy, and central atrophy (ventricular sizes) were measured at CT scans. Compared with women reporting no distress, those reporting frequent or constant distress at one examination or more (in 1968, 1974, and 1980) more often had moderate-to-severe WMLs (multiadjusted odds ratio = 2.39, 95% confidence interval = 1.16-4.92) and moderate-to-severe temporal lobe atrophy (multiadjusted odds ratio = 2.51, 95% confidence interval = 1.04-6.05) on brain CT in 2000. Frequent/constant distress was also associated with central brain atrophy, that is, higher bicaudate ratio, higher cella media ratio, and larger third-ventricle width. Long-standing psychological distress in midlife increases risks of cerebral atrophy and WMLs on CT in late life. More studies are needed to confirm these findings and to determine potential neurobiological mechanisms of these associations.

- Department of Primary Health Care, Sahlgrenska Academy at Göteborg University, Göteborg, Sweden. lauren.lissner@medfak.gu.se OBJECTIVE: To describe a cohort study of women receiving a series of comprehensive health examinations over 32 years. DESIGN: Longitudinal population study based on a randomised sample of the female population from defined age cohorts. SETTING: City of Göteborg, Sweden. SUBJECTS: Subjects were 38, 46, 50, 54 or 60 years old at the start of the study in 1968. Re-examinations were performed in 1974, 1982 and 1992. Non-participants in the most recent examination, initiated in 2000, were offered home visits. MAIN OUTCOME MEASURES: Participation, anthropometric and blood pressure changes. RESULTS: At the end of the 32-year follow-up, 64% of the original participants were alive, and low participation among survivors was a problem. An acceptable participation rate (71% of those alive) was obtained after home visits were offered. Surviving non-participants already had elevated cardiovascular risk factors at onset of the study in 1968, along with lower educational level and lower socioeconomic status. Home visited subjects were similar to non-participants with regard to anthropometry and blood pressure, but did not differ from participants with regard to social indicators. Thirty-two-year longitudinal data demonstrate clear ageing effects for several important variables, which should, however, be considered in the context of documented differences with non-participants at the baseline examination. CONCLUSIONS: Longitudinal studies in elderly populations provide important data on changes during the ageing process. However, participation rates decline for a number of reasons and generalisations should be made with care. Moreover, including home visits in the protocol can both increase participation and reduce participation bias in elderly cohorts. PMID: 14695076 [PubMed - indexed for MEDLINE]

- The objective of this study was to assess the association between different types of alcoholic beverages and 34-year incidence of dementia. Among a random sample of 1,462 women aged 38-60 years and living in Göteborg, Sweden, in 1968-1969, 164 cases of dementia were diagnosed by 2002. At baseline as well as in 1974-1975, 1980-1981, and 1992-1993, the frequency of alcohol intake, as well as other lifestyle and health factors, was recorded and related to dementia with Cox proportional hazard regression, by use of both baseline and updated covariates. Wine was protective for dementia (hazard ratio (HR) = 0.6, 95% confidence interval (CI): 0.4, 0.8) in the updated model, and the association was strongest among women who consumed wine only (HR = 0.3, 95% CI: 0.1, 0.8). After stratification by smoking, the protective association of wine was stronger among smokers. In contrast, consumption of spirits at baseline was associated with slightly increased risk of dementia (HR = 1.5, 95% CI: 1.0, 2.2). Results show that wine and spirits displayed opposing associations with dementia. Because a protective effect was not seen for the other beverages, at least part of the association for wine may be explained by components other than ethanol.

Tidskriftsartikel (refereegranskat)abstract
- In a representative population of women followed over 34 years, we investigated the prospective association between fasting serum insulin and dementia, taking into account the incidence of diabetes mellitus.Fasting values for serum insulin and blood glucose were obtained in 1,212 nondiabetic women 38 to 60 years of age at the 1968 baseline. Risk of dementia was assessed by Cox proportional hazard regression with adjustment for insulin, glucose, and other covariates and, in a second model, after censoring for incident cases of diabetes mellitus. Incident diabetes mellitus was considered as a third endpoint for comparison with dementia.Over 34 years, we observed 142 incident cases of dementia. The low tertile of insulin displayed excess risk for dementia (hazard ratio [HR] 2.34, 95% confidence interval [CI] 1.52-3.58) compared to the medium tertile, but the high tertile of insulin did not (HR 1.28, 95% CI 0.81-2.03). These associations were also seen for dementia without diabetes comorbidity. In contrast, high but not low insulin predicted incident diabetes mellitus (115 cases) (HR 1.70, 95% CI 1.08-2.68 and HR 0.76, 95% CI 0.43-1.37, respectively).A previous study reported a U-shaped association between fasting insulin and dementia in a 5-year follow-up of elderly men. Our results confirmed a nonlinear association in a female population, with high risk at low insulin values that was not attributable to preclinical dementia or impaired insulin secretion. This condition suggests a new pathway to dementia, which differs from the metabolic pathway involving diabetes mellitus.
