The aims of this study were to determine the association between midlife physical activity and late-life disability and to investigate gender-specific differences. Method This data originates from the KORA-Age cohort, a follow-up in 2008 of the MONICA (Multinational Monitoring of Trends and Determinants in Cardiovascular Diseases)/KORA (Cooperative Health Research in the Region of Augsburg) S1-S4 surveys (1984-2001) situated in Augsburg, a city in Southern Germany. We applied a multivariable hurdle model to investigate the association of physical activity and disability. Results We analysed 3333 persons with a mean follow-up of 18 ± 5.5 years. Using hurdle models, moderate activity and high activity had a protective effect on the occurrence of disability (OR (odds ratio) = 0.80 and 0.73), but not on severity (i.e. number of limitations). We observed a strong gender-specific difference in this association, with men benefitting more from exercise. Conclusion Elevated physical activity reduces the risk of becoming disabled and postpones the onset of disability by several years, but we could not show an effect on the severity of disability. In addition, men seem to benefit more from leisure-time physical activity than women}, language = {en} } @article{MuellerStroblJahnetal.2014, author = {M{\"u}ller, Martin and Strobl, R. and Jahn, K. and Linkohr, B. and Ladwig, K.H. and Mielk, A. and Grill, E.}, title = {Impact of vertigo and dizziness on self-perceived participation and autonomy in older adults: Results from the KORA-Age study}, series = {Quality of life research}, journal = {Quality of life research}, editor = {Springer Link,}, year = {2014}, abstract = {Purpose The impact of vertigo and dizziness on healthy ageing, and especially on participation, is not fully understood. The objective of this study was to investigate the association of vertigo and dizziness with self-perceived participation and autonomy in older non-institutionalised individuals, adjusted for the presence of other health conditions. Specifically, we wanted to investigate the different effects of vertigo and dizziness on specific components of participation, i.e. restrictions in indoor and outdoor autonomy, family role, social life and relationships, and work and education. Methods Data originate from the second wave of the German KORA-Age cohort study collected in 2012. Participation and autonomy was investigated with the Impact on Participation and Autonomy Questionnaire. We used robust regression to analyse the association of vertigo and dizziness with self-perceived participation and autonomy adjusted for covariates. Results A total of 822 participants (49.6 \% female) had a mean age of 78.1 years (SD 6.39). Participation and autonomy were significantly lower in participants with vertigo and dizziness across all domains. Adjusted for age, sex, and chronic conditions, vertigo and dizziness were significantly associated with participation restrictions in all domains except social life and relationships. Conclusion The results of our study indicate that vertigo and dizziness contribute to restrictions in participation and autonomy in individuals of older age. Recognising vertigo and dizziness as independent contributors to loss of autonomy and decreased chances for independent living may create new options for patient care and population health, such as the designing of complex interventions to maintain participation and autonomy.}, language = {en} }
