  • Secular trends in self reported sexual activity and satisfaction in Swedish 70 year olds: cross sectional survey of four populations, 1971-2001.
  • 2008
  • Ingår i: BMJ (Clinical research ed.). - 1468-5833. ; 337
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To study secular trends in self reported sexual behaviour among 70 year olds. DESIGN: Cross sectional survey. Settings Four samples representative of the general population in Gothenburg, Sweden. PARTICIPANTS: 1506 adults (946 women, 560 men) examined in 1971-2, 1976-7, 1992-3, and 2000-1. MAIN OUTCOME MEASURES: Sexual intercourse, attitudes to sexuality in later life, sexual dysfunctions, and marital satisfaction. RESULTS: From 1971 to 2000 the proportion of 70 year olds reporting sexual intercourse increased among all groups: married men from 52% to 68% (P=0.002), married women from 38% to 56% (P=0.001), unmarried men from 30% to 54% (P=0.016), and unmarried women from 0.8% to 12% (P<0.001). Men and women from later birth cohorts reported higher satisfaction with sexuality, fewer sexual dysfunctions, and more positive attitudes to sexuality in later life than those from earlier birth cohorts. A larger proportion of men (57% v 40%, P<0.001) and women (52% v 35%, P<0.001) reported very happy relationships in 2000-1 compared with those in 1971-2. Sexual debut before age 20 increased in both sexes: in men from 52% to 77% (P<0.001) and in women from 19% to 64% (P<0.001). CONCLUSION: Self reported quantity and quality of sexual experiences among Swedish 70 year olds has improved over a 30 year period.

  • Are sedatives and hypnotics associated with increased suicide risk of suicide in the elderly?
  • 2009
  • Ingår i: BMC geriatrics. - 1471-2318. ; 9:20
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: While antidepressant-induced suicidality is a concern in younger age groups, there is mounting evidence that these drugs may reduce suicidality in the elderly. Regarding a possible association between other types of psychoactive drugs and suicide, results are inconclusive. Sedatives and hypnotics are widely prescribed to elderly persons with symptoms of depression, anxiety, and sleep disturbance. The aim of this case-control study was to determine whether specific types of psychoactive drugs were associated with suicide risk in late life, after controlling for appropriate indications. METHODS: The study area included the city of Gothenburg and two adjacent counties (total 65+ population 210 703 at the start of the study). A case controlled study of elderly (65+) suicides was performed and close informants for 85 suicide cases (46 men, 39 women mean age 75 years) were interviewed by a psychiatrist. A population based comparison group (n = 153) was created and interviewed face-to-face. Primary care and psychiatric records were reviewed for both suicide cases and comparison subjects. All available information was used to determine past-month mental disorders in accordance with DSM-IV. RESULTS: Antidepressants, antipsychotics, sedatives and hypnotics were associated with increased suicide risk in the crude analysis. After adjustment for affective and anxiety disorders neither antidepressants in general nor SSRIs showed an association with suicide. Antipsychotics had no association with suicide after adjustment for psychotic disorders. Sedative treatment was associated with an almost fourteen-fold increase of suicide risk in the crude analyses and remained an independent risk factor for suicide even after adjustment for any DSM-IV disorder. Having a current prescription for a hypnotic was associated with a four-fold increase in suicide risk in the adjusted model. CONCLUSION: Sedatives and hypnotics were both associated with increased risk for suicide after adjustment for appropriate indications. Given the extremely high prescription rates, a careful evaluation of the suicide risk should always precede prescribing a sedative or hypnotic to an elderly individual.

  • Personality and risk for depression in a birth cohort of 70-year-olds followed for 15 years.
  • 2008
  • Ingår i: Psychological medicine. - 0033-2917. ; 38:5, s. 663-71
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The association between personality traits and the first lifetime onset of clinically significant depression has not been studied in older adults. METHOD: Experienced psychiatrists conducted interviews and chart reviews at baseline and throughout the 15-year follow-up period. Survival analyses were conducted on the presence/absence of a DSM-III-R mood disorder at follow-up. RESULTS: There were 59 cases of first lifetime episodes of depression. Analyses showed that Neuroticism [hazard ratio (HR) per one point increase in the Maudsley Personality Inventory (MPI)=1.05, 95% confidence interval (CI) 1.02-1.08] but not Extroversion (HR 1.02, 95% CI 0.97-1.06) amplified risk for mood disorder. CONCLUSIONS: This prospective study on a randomly sampled birth cohort of older adults showed that Neuroticism confers risk for a first lifetime episode of clinically significant depression. Findings have implications for understanding the etiology of late-life depression (LLD) and could also aid in the identification and treatment of people at risk.

  • The relationship between cerebrospinal fluid biomarkers and depression in elderly women.
  • 2007
  • Ingår i: The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry. - 1064-7481. ; 15:10, s. 832-8
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Cerebrospinal fluid (CSF) biomarkers including the 42 amino-acid form of beta-amyloid (Abeta42), total tau protein (T-tau), and the CSF/serum albumin ratio are markers of brain pathology and metabolism. Abeta42 and T-tau are sometimes used to discriminate geriatric depression from mild forms of Alzheimer disease (AD) in clinical studies. However, studies focusing on the relationship between these CSF biomarkers and geriatric depression are lacking. METHODS: This was a cross-sectional study with a population-based sample of 84 nondemented elderly women in Sweden. Measurements included neuropsychiatric, physical, and lumbar puncture examinations, with Diagnostic and Statistical Manual of Mental Disorders, Third Revision-based depression diagnoses and measurement of CSF levels of Abeta42, T-tau, albumin, and serum albumin. RESULTS: Fourteen women (mean age: 72.6 years) had any depression (11 with major depressive disorder [MDD]). Compared to women without depression, women with MDD had higher levels of Abeta42 and the CSF/serum albumin ratio. The CSF/serum albumin ratio was also higher in women with any depression. No differences in T-tau were observed; however, T-tau increased with age. CONCLUSION: Higher levels of CSF Abeta42 were observed among elderly depressed women, in contrast to lower levels usually observed in AD, indicating potential neuropathological differences between the two disorders. Higher CSF/serum albumin ratios observed in depressed women point to potential vascular processes.

    • 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.
