Who Benefited the Most? Effectiveness of a Lifestyle Intervention Against Cognitive Decline in Older Women and Men - Secondary Analysis of the AgeWell.de-trial.

INTRODUCTION: Differences between women and men matter in the prevalence and risk factors of dementia. We aimed to examine potential sex differences regarding the effectiveness by running a secondary analysis of the AgeWell.de trial, a cluster-randomized multicenter multi-domain lifestyle intervention to reduce cognitive decline. METHODS: Intention-to-treat analyses of women (n=433) and men (n=386) aged 60 to 77 years were used for models including interactions between intervention group allocation and sex followed by subgroup analysis stratified by sex on primary and secondary outcomes. Further, the same procedure was repeated for age groups (60-69 vs. 70-77) within sex-specific subgroups to assess the effectiveness in different age groups. TRIAL REGISTRATION: German Clinical Trials Register (ref. number: DRKS00013555). RESULTS: No differences were found between women and men in the effectiveness of the intervention on cognitive performance. However, women benefitted from the intervention regarding depressive symptoms while men did not. Health-related quality of life was enhanced for younger intervention participants (60-69 years) in both women and men. CONCLUSION: The AgeWell.de intervention was able to improve depressive symptoms in women and health-related quality of life in younger participants. Female participants between 60 and 69 years benefited the most. Results support the need of better individually targeted lifestyle interventions for older adults.

Medical students' knowledge and attitudes regarding vaccination against measles, influenza and HPV. An international multicenter study.

INTRODUCTION: Inaccurate information leads to increased scepticism concerning vaccinations among health care workers. Therefore, a proper education of medical students on vaccination is important. METHODS: During summer term 2015, we performed a paper-based survey to identify the knowledge and attitudes of medical students on vaccinations against measles, influenza and HPV in seven medical schools in Germany, Austria and Switzerland. RESULTS: Altogether, 3,652 questionnaires were analyzed. Knowledge of country-specific public recommendations increased significantly with the number of semesters of medical studies. Concerning the knowledge about vaccinations against measles, influenza and HPV, one third of the answers were given correctly. Again, a strong correlation between the knowledge and the semester of medical studies could be observed. The attitudes concerning vaccinations in general and especially for HCWs were highly positive. CONCLUSIONS: This study provides some important arguments for the development of a comprehensive vaccination education for medical students.
