  • Personality in women and associations with mortality: a 40-year follow-up in the Population Study of Women in Gothenburg
  • 2014
  • Ingår i: BMC Women's Health. - 1472-6874. ; 14:61
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

    • Neuropsychiatric Epidemiology Unit, Institute of Clinical Neurosciences, Sahlgrenska Academy at Göteborg University, SE 413 45 Göteborg, Sweden. xinxin.guo@neuro.gu.se <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]

  • Adiposity indicators and dementia over 32 years in Sweden
  • 2009
  • Ingår i: Neurology. - 1526-632X. ; 73:19, s. 1559-66
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: High midlife and late-life adiposity may increase risk for dementia. Late-life decrease in body mass index (BMI) or body weight within several years of a dementia diagnosis has also been reported. Differences in study designs and analyses may provide different pictures of this relationship. METHODS: Thirty-two years of longitudinal body weight, BMI, waist circumference, and waist-to-hip ratio (WHR) data, from the Prospective Population Study of Women in Sweden, were related to dementia. A representative sample of 1,462 nondemented women was followed from 1968 at ages 38-60 years, and subsequently in 1974, 1980, 1992, and 2000, using neuropsychiatric, anthropometric, clinical, and other measurements. Cox proportional hazards regression models estimated incident dementia risk by baseline factors. Logistic regression models including measures at each examination were related to dementia among surviving participants 32 years later. RESULTS: While Cox models showed no association between baseline anthropometric factors and dementia risk, logistic models showed that a midlife WHR greater than 0.80 increased risk for dementia approximately twofold (odds ratio 2.22, 95% confidence interval 1.00-4.94, p = 0.049) among surviving participants. Evidence for reverse causality was observed for body weight, BMI, and waist circumference in years preceding dementia diagnosis. CONCLUSIONS: Among survivors to age 70, high midlife waist-to-hip ratio may increase odds of dementia. Traditional Cox models do not evidence this relationship. Changing anthropometric parameters in years preceding dementia onset indicate the dynamic nature of this seemingly simple relationship. There are midlife and late-life implications for dementia prevention, and analytical considerations related to identifying risk factors for dementia.

  • Leptin and dementia over 32 years-The Prospective Population Study of Women
  • 2012
  • Ingår i: Alzheimers & Dementia. - 1552-5260. ; 8:4, s. 272-277
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

    • OBJECTIVE: To study the relation among psychosocial stressors, long-standing distress and incidence of dementia, in a sample of women followed from midlife to late life. DESIGN: Prospective longitudinal population study. SETTING: The analyses originate from the prospective population study of women in Gothenburg, Sweden, a representative sample of women examined in 1968 (participation rate 90%) and re-examined in 1974, 1980, 1992, 2000 and 2005. PARTICIPANTS: 800 women born in 1914, 1918, 1922 and 1930 who were systematically selected for a psychiatric examination at baseline, in 1968. PRIMARY AND SECONDARY OUTCOME MEASURES: 18 psychosocial stressors (eg, divorce, widowhood, work problems and illness in relative) were obtained at baseline. Symptoms of distress were measured according to a standardised question at each study wave. Dementia was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) criteria based on information from neuropsychiatric examinations, informant interviews, hospital records, and registry data, and measured through the whole study period. RESULTS: During the 37 years of follow-up, 153 women developed dementia (104 of those had Alzheimer's disease (AD)). Number of psychosocial stressors in 1968 was associated (HR, 95% CI) with higher incidence of dementia (1.15, 1.04 to 1.27) and AD (1.20, 1.07 to 1.35) between 1968 and 2005, in multivariate Cox regressions. Number of psychosocial stressors in 1968 was also associated (OR, 95% CI) with distress in 1968 (1.48, 1.32 to 1.67), 1974 (1.31, 1.17 to 1.46), 1980 (1.27, 1.11 to 1.45), 2000 (1.39, 1.14 to 1.70) and 2005 (1.35, 1.02 to 1.79), in multivariate logistic regressions. Number of psychosocial stressors (HR 1.17, 95% CI 1.03 to 1.33) and long-standing distress (1968-1974-1980) (HR 1.58, 95% CI 1.03 to 2.45) were independently associated with AD. CONCLUSIONS: Our study shows that common psychosocial stressors may have severe and long-standing physiological and psychological consequences. However, more studies are needed to confirm these results and investigate whether more interventions such as stress management and behavioural therapy should be initiated in individuals who have experienced psychosocial stressors.

  • Midlife Psychological Distress Associated With Late-Life Brain Atrophy and White Matter Lesions: A 32-Year Population Study of Women.

    • 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.

    • The number of people with dementia has increased dramatically with global ageing. Nevertheless, the pathogeneses of these diseases are not sufficiently understood. The present study aims to analyse the relationship between psychological stress in midlife and the development of dementia in late-life. A representative sample of females (n = 1462) aged 38-60 years were examined in 1968-69 and re-examined in 1974-75, 1980-81, 1992-93 and 2000-03. Psychological stress was rated according to a standardized question in 1968, 1974 and 1980. Dementia was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders criteria based on information from neuropsychiatric examinations, informant interviews, hospital records and registry data. During the 35-year follow-up, 161 females developed dementia (105 Alzheimer's disease, 40 vascular dementia and 16 other dementias). We found that the risk of dementia (hazard ratios, 95% confidence intervals) was increased in females reporting frequent/constant stress in 1968 (1.60, 1.10-2.34), in 1974 (1.65, 1.12-2.41) and in 1980 (1.60, 1.01-2.52). Frequent/constant stress reported in 1968 and 1974 was associated with Alzheimer's disease. Reporting stress at one, two or three examinations was related to a sequentially higher dementia risk. Compared to females reporting no stress, hazard ratios (95% confidence intervals) for incident dementia were 1.10 (0.71-1.71) for females reporting frequent/constant stress at one examination, 1.73 (1.01-2.95) for those reporting stress at two examinations and 2.51 (1.33-4.77) at three examinations. To conclude, we found an association between psychological stress in middle-aged women and development of dementia, especially Alzheimer's disease. More studies are needed to confirm our findings and to study 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]
