This population-based study examined 10,000 participants randomly selected from the Leipzig population (2011 to 2014). A follow-up is to be carried out from 2017 - 2020. The study mainly included people aged between 40 and 79. All participants underwent a 6-hour study program and people over 60 years of age were invited two more times to in-depth study of cognition and depression and the brain (MRI, EEG). Extensive measurements of genome, metabolome and transcriptome are available. The LIFE-ADULT

The association between mental demands at the workplace and cognitive functioning: the role of the big five personality traits.
LIFE Adult

Abstract (Expand)

<b>Objectives:</b> Mental demands at the workplace can be preventive against cognitive decline. However, personality shapes the way information is processed and we therefore assume that … Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness, would moderate the beneficial effects of workplace stimulation on cognitive outcomes. <b>Methods:</b> We analyzed data from the population-based LIFE-Adult-Study (n = 6529). Cognitive outcomes were assessed via the Trail-Making Test (TMTA, TMTB) and the Verbal Fluency Test. Personality was assessed via the Personality Adjective List (16 AM). Mental demands were classified with the indices Verbal and Executive based on the O*NET database. <b>Results:</b> Multivariate regression analyses showed only two significant moderation effects of personality, i.e. in individuals with low scores on Conscientiousness/Openness, index Verbal was connected to better TMTB performance, while this effect disappeared for individuals with high values on the personality trait. However, the additional explained variance remained marginal. <b>Conclusion:</b> The findings suggest that personality does not modify associations between high mental demands at work and better cognitive functioning in old age; however, there is a tendency that high levels of Openness and Conscientiousness may offset effects of mental demands.

Olfactory function is associated with cognitive performance: results from the population-based LIFE-Adult-Study.
LIFE Adult

Abstract (Expand)

BACKGROUND: Studies in older adults or those with cognitive impairment have shown associations between cognitive and olfactory performance, but there are few population-based studies especially in … younger adults. We therefore cross-sectionally analyzed this association using data from the population-based LIFE-Adult-Study. METHODS: Cognitive assessments comprised tests from the Consortium to Establish a Registry for Alzheimer's Disease (CERAD): verbal fluency (VF), word list learning and recall (WLL, WLR), and the Trail Making Tests (TMT) A and B. The "Sniffin' Sticks Screening 12" test was used to measure olfactory performance. Linear regression analyses were performed to determine associations between the number of correctly identified odors (0 to 12) and the five cognitive test scores, adjusted for sex, age, education, and the presence of depressive symptoms. Receiver operating characteristic (ROC) analysis was carried out to determine the discriminative performance of the number of correctly identified odors regarding identification of cognition impairment. RESULTS: A total of 6783 participants (51.3% female) completed the olfaction test and the VF test and TMT. A subgroup of 2227 participants (46.9% female) also completed the WLL and WLR tests. Based on age-, sex-, and education-specific norms from CERAD, the following numbers of participants were considered cognitively impaired: VF 759 (11.2%), WLL 242 (10.9%), WLR: 132 (5.9%), TMT-A 415 (6.1%), and TMT-B/A ratio 677 (10.0%). On average, score values for VF were higher by 0.42 points (p < 0.001), for WLL higher by 0.32 points (p = 0.001), for WLR higher by 0.31 points (p = 0.002), for TMT-A lower by 0.25 points (p < 0.001), and for TMT-B/A ratio lower by 0.01 points (p < 0.001) per number of correctly identified odors. ROC analysis revealed area under the curve values from 0.55 to 0.62 for the five cognitive tests. CONCLUSIONS: Better olfactory performance was associated with better cognitive performance in all five tests in adults - adjusted for age, sex, education, and the presence of depressive symptoms. However, the ability of the smell test to discriminate between individuals with and without cognitive impairment was limited. The value of olfactory testing in early screening for cognitive impairment should be investigated in longitudinal studies.

Olfactory dysfunction: properties of the Sniffin' Sticks Screening 12 test and associations with quality of life.
LIFE Adult

Abstract (Expand)

PURPOSE: The Sniffin' Sticks Screening 12 test is a test of olfactory performance based on pen-like odor dispensing devices. The aims of this study were to analyze the performance of this test in … a general population sample and to explore associations between olfactory dysfunction and quality of life. METHODS: A large community sample (n = 7267) completed the Sniffin' Sticks Screening 12 test and several questionnaires measuring quality of life, anxiety, dispositional optimism, social support, and satisfaction with life. RESULTS: According to the criteria recommended by the test manufacturer, 5.1% of the participants were anosmic (score </= 6), 52.4% were dysosmic (7 </= score </= 10), and 42.5% were normosmic (score >/= 11). While frequencies of correct identification differed between the 12 sticks, all sticks contributed positively to the test results. The associations between olfactory functioning and quality of life variables were negligible. In the multivariate analyses, none of the associations reached the 1% significance level. CONCLUSIONS: While studies with patients in otorhinolaryngological clinics often report substantial detriments to their quality of life in relation to olfactory dysfunction, the present epidemiological study cannot confirm this association for the general population.

[Indication and Evidence of Internationally Developed Online Coaches as Intervention for Mental Illness - a Meta-Review].
LIFE Adult

Abstract (Expand)

OBJECTIVE: The aim of the study was to investigate the current state of research concerning internationally developed Online Coaches for treatment support and prevention of mental disorders. Evidence … and effectiveness of the Online Coaches ought to be explored. METHODS: A systematic literature search was performed in international databases in order to provide a meta-review of existing Online Coaches for mental disorders. The assessment of the methodological quality and evidence of the studies was based on the established guidelines of the Scottish Intercollegiate Guideline Network. RESULTS: 52 studies (24 meta-analyses, 16 systematic reviews, 2 health-technology assessment reports, and 10 RCT studies) were identified. The efficacy was demonstrated for a variety of Online Coaches for mental disorders, especially for anxiety and depressive disorders, insomnia, and post-traumatic stress disorders, with predominantly acceptable and high quality. CONCLUSION: The present work provides an overview of internationally developed Online Coaches in the field of mental health care. Online Coaches can serve as a useful supplement to the treatment and prevention of mental disorders.

Effects of psychological eating behaviour domains on the association between socio-economic status and BMI.
LIFE Adult

Abstract (Expand)

OBJECTIVE: The current study investigates potential pathways from socio-economic status (SES) to BMI in the adult population, considering psychological domains of eating behaviour (restrained eating, … uncontrolled eating, emotional eating) as potential mediators stratified for sex. DESIGN: Data were derived from the population-based cross-sectional LIFE-Adult-Study. Parallel-mediation models were conducted to obtain the total, direct and indirect effects of psychological eating behaviour domains on the association between SES and BMI for men and for women. SETTING: Leipzig, Germany. SUBJECTS: We studied 5935 participants aged 18 to 79 years. RESULTS: Uncontrolled eating mediated the association between SES and BMI in men only and restrained eating in both men and women. Emotional eating did not act as mediator in this relationship. The total effect of eating behaviour domains on the association between SES and BMI was estimated as beta=-0.03 (se 0.02; 95 % CI -0.062, -0.003) in men and beta=-0.18 (se 0.02; 95 % CI -0.217, -0.138) in women. CONCLUSIONS: Our findings do not indicate a strong overall mediation effect of the eating behaviour domains restrained eating, uncontrolled eating and emotional eating on the association between SES and BMI. Further research on other pathways of this association is strongly recommended. Importantly, our findings indicate that, independent from one's social position, focusing on psychological aspects in weight reduction might be a promising approach.
