- Associations of Gait Speed, Cadence, Gait Stability Ratio, and Body Balance with Falls in Older AdultsPublication . Nascimento, Marcelo de Maio; Gouveia, Élvio Rúbio; Gouveia, Bruna R.; Marques, Adilson; Martins, Francisco; Przednowek, Krzysztof; França, Cíntia; Peralta, Miguel; Ihle, AndreasTo investigate the association between gait speed (GS), cadence (CAD), gait stability ratio (GSR), and body balance (BB) with falls in a large sample of older adults. The analysis included 619 individuals—305 men and 314 women (69.50 ± 5.62 years)—residing in the Autonomous Region of Madeira, Portugal. Mobility in GS, CAD, and GSR was assessed using the 50-foot walk test and BB by the Fullerton Advanced Balance scale. The frequency of falls was obtained by self-report. Linear regression analysis showed that higher performance in GS and BB was able to reduce the risk of falling by up to 0.34 and 0.44 times, respectively. An increase in the GSR value enhanced the risk of falling by up to 0.10 times. Multinomial analysis indicated that, in relation to the highest tertile (reference), older adults classified with GS and BB performance in the lowest tertile (lowest) had an increased chance (OR) of falling by up to 149.3% and 48.8%, respectively. Moreover, in relation to the highest tertile, the performance of the GSR classified in the lowest and medium tercile showed an increase in the chance of falling by up to 57.4% and 56.4%, respectively
- Balance and mobility relationships in older adults: A representative population-based cross-sectional study in Madeira, PortugalPublication . Gouveia, Élvio R.; Gouveia, Bruna R.; Ihle, Andreas; Kliegel, Matthias; Marques, Adilson; Freitas, Duarte L.Background: Balance and mobility impairments are important modifiable risk factors associated with falls in older people. Purpose: To investigate how different functional fitness components relate to balance and mobility, after controlling for age, sex, body mass index (BMI), and different physical activity (PA) domains. Methods: This representative cross-sectional study included 802 individuals, 401 males and 401 females (69.8 ± 5.6 years) from Madeira, Portugal. The Fullerton Advance Balance (FAB) scale was used to assess balance. Mobility in terms of gait velocity, cadence, stride length, and gait stability ratio (GSR) were assessed using the 50-foot Walk test. PA was assessed through a face-to-face interview using the Baecke questionnaire, and functional fitness was assessed with Senior Fitness tests (strength, flexibility, and aerobic endurance). Results: Balance and mobility were negatively associated with age and BMI, and positively related to PA and functional fitness. Moreover, male presented better performance in balance and mobility. Hierarchical multiple regression analyses showed that functional fitness explained the highest amount of variance in balance and all mobility parameters(over andaboveage,sex,BMI,and PA).Specifically, entering functional fitnesscomponents significantly increased explained variance in FAB (+19%), gait velocity (+25%), cadence (+15%), stride length (+9%), and GSR (+ 31%). In these models, aerobic endurance consistently had the strongest contribution. Conclusion: Strength, flexibility, and especially aerobic endurance, over and above non-modifiable variables like age and sex, are crucial for maintaining or improving balance and mobility and, thereby, prevent falls in older people.
- Cognitive Functioning Mediates the Association of Cognitive Reserve with Health-Related Quality of LifePublication . Ihle, Andreas; Gouveia, Élvio R.; Gouveia, Bruna R.; Marques, Adilson; Marconcin, Priscila; Nascimento, Marcelo de Maio; Jurema, Jefferson; Tinôco, Maria A.; Kliegel, MatthiasWe investigated whether the relations of the cognitive reserve markers education and cogni tive level of work to the physical and the mental component of health-related quality of life (HRQoL) were mediated via cognitive functioning in a large sample of 701 older adults (mean age = 70.36 years, SD = 6.87). HRQoL was measured with the 12-item Short-Form Health Survey. To measure cog nitive functioning, we used the COGTEL, which is a cognitive test battery assessing prospective memory, verbal short-term memory, verbal long-term memory, working memory, verbal fluency, and inductive reasoning, combined into a composite score. Individuals reported information on their education and their main profession during their working life. Mediation analyses showed that better cognitive functioning mediated the association of higher values in the cognitive reserve markers (longer education and a high cognitive level of work) with higher HRQoL. In conclusion, the present study suggests that the sustainability of cognitive functioning in old age with the help of cognitive reserve is fundamental for the sustainability of quality of life, presumably particularly for the mental HRQoL component.
- Cognitive reserve attenuates 6-year decline in executive functioning after strokePublication . Ihle, Andreas; Gouveia, Élvio R.; Gouveia, Bruna R.; Cheval, Boris; Sieber, Stefan; Cullati, Stéphane; Kliegel, MatthiasAims: We investigated whether the longitudinal relationship between history of stroke and subsequent decline in executive functioning over 6 years differed by cognitive reserve. Methods: We analyzed longitudinal data from 897 older adults (mean age, 74.33 years) tested on the Trail Making Test (TMT) in two waves 6 years apart. Participants reported information on key frequently used proxies of lifelong cognitive reserve accumulation (i.e., education, occupation, and leisure activity engagement), and history of stroke. Results: There was a significant interaction of stroke with leisure activity engagement on latent change in executive functioning. Specifically, only for individuals with low (but not those with high) leisure activity engagement, history of stroke significantly predicted a steeper subsequent decline in executive functioning across 6 years (i.e., increases in TMT completion time). Conclusion: The detrimental aftereffects of stroke on subsequent decline in executive functioning may be attenuated in individuals who have accumulated greater cognitive reserve through leisure activity engagement across their life.
- Cognitive Reserve Mediates the Relation between Neighborhood Socio-Economic Position and Cognitive DeclinePublication . Ihle, Andreas; Gabriel, Rainer; Oris, Michel; Gouveia, Élvio R.; Gouveia, Bruna R.; Marques, Adilson; Marconcin, Priscila; Kliegel, MatthiasWe investigated the mediating role of leisure activity engagement as marker of cognitive reserve in the relation between neighborhood socio-economic position (SEP) and cognitive decline over 6 years. Methods: The study analyzed longitudinal data from 897 older adults who par ticipated in the two waves (2011 and 2017) of the Vivre-Leb en-Vivere (VLV) survey in Switzerland (M = 74.33 years in the first wave). Trail Making Test parts A and B were adminis tered in both waves. Leisure activity engagement was as sessed during interviews. Neighborhood SEP was derived from the Swiss Neighborhood Index of Socio-Economic Position (Swiss-SEP), provided by the Swiss National Cohort (SNC). Results: Latent change score modeling revealed that 42.5% of the relationship between higher neighborhood SEP and smaller cognitive decline was mediated via a higher frequency of leisure activities in the first wave. Conclusion: Neighborhood SEP constitutes an important contextual fac tor potentially influencing the pathways of cognitive reserve accumulation and, therefore, should be taken into account to better understand their effects on cognitive decline in old age.
- Correlações da qualidade de vida relacionada à saúde em pessoas Idosas da Região Autónoma da MadeiraPublication . Gouveia, Élvio R.; Gouveia, Bruna R.; Ihle, Andreas; Marques, Adilson; Kliegel, Matthias; Freitas, Duarte L.O objetivo deste estudo foi investigar o papel dos preditores da qualidade de vida relacionada com a saúde (QVRS) em pessoas idosas, e analisar se essas relações diferem em função da componente da QVRS (física vs. mental) e/ou intervalo etário (jovem-idoso vs. idoso-idoso). Este estudo incluiu 802 idosos com idade entre 60 e os 79 anos. A QVRS foi avaliada através do questionário SF-36. A aptidão funcional foi avaliada usando a bateria de testes Senior Fitness Test. A atividade física, as informações demográficas e de saúde foram obtidas via questionário. Uma análise de regressão múltipla mostrou que o índice de massa corporal (β=−0,15, p=0,001), a força muscular (β=0,21, p<0,001), a resistência aeróbia (β=0,29, p<0,001), a atividade física (β=0,11, p=0,007), os sintomas depressivos (β=−0,19, p<0,001), as quedas (β=−0,19, p<0,001) e viver sozinho (β=−0,16, p<0,001) foram preditores significativos do score total do SF-36. Verificou-se ainda uma relação positiva entre a componente física com a resistência aeróbia, e uma relação negativa entre o viver sozinho componente mental da QVRS. A relação positiva entre a atividade física e a QVRS foi verificada apenas nos idosos-idosos. Estes dados sugerem que a composição corporal, a aptidão funcional, os fatores psicossociais e as quedas são preditores importantes da QVRS. Existem diferenças nas relações entre as componentes da QVRS e os preditores em função do intervalo etário, o que sugere a necessidade de planear estratégias específicas no nível da comunidade para promover a QVRS em pessoas idosas mais velhas.
- Differential Patterns in Motivations for Practicing Sport and Their Effects on Physical Activity Engagement across the LifespanPublication . Nascimento, Marcelo de Maio; Gouveia, Élvio Rúbio; Gouveia, Bruna R.; Marques, Adilson; França, Cíntia; Campos, Pedro Filipe Pereira; Martins, Francisco; García-Mayor, Jesús; Ihle, AndreasThis study aims to report what motivates individuals to be physically active, to determine whether motivating factors influence physical activity (PA) levels, and whether this differs across the lifespan. This is a cross-sectional study with 498 individuals: 117 adolescents, 306 adults, and 75 older adults. PA was assessed using Baecke’s questionnaire, and motivating factors for practicing sports were investigated using a scale with twelve questions. The factor analysis identified three motivating factors for sports practice: psychosocial, bodily, and well-being. The scale’s overall reliability and internal consistency indicated a Cronbach’s alpha of 0.885. The analysis of covariance (ANCOVA) adjusted for sex indicated the three factors as having a significant effect on PA (p < 0.050); however, only the well-being factor showed a significant interaction with age groups (p = 0.023, ηp 2 = 0.030). Subsequently, the effect of the well-being factor on PA scores in each age group was explored through regression analyses. Only older adults showed a significant association in the unadjusted [OR = 0.378, p = 0.001, R2 = 0.243] and the sex-adjusted analysis [OR = 0.377, p = 0.001, R2 = 0.288]. These results help us to better understand the underlying motivational reasons in different age groups for engaging in sports.
- Estimation of engagement in moderate-to-vigorous physical activity from direct observation: a proposal for school physical educationPublication . Gouveia, Élvio R.; Gouveia, Bruna R.; Marques, Adilson; Lopes, Hélder; Rodrigues, Ana; Quintal, Tomás; Pestana, Marcelo; Peralta, Miguel; Kliegel, Matthias; Ihle, AndreasThis study aimed to test an observational momentary time sampling tool to estimate in class moderate-to-vigorous physical activity (MVPA), in terms of validity, reliability and agreement between observational momentary time sampling and accelerometry, and to develop a regression equation to estimate MVPA from observational momentary time sampling. The sample comprised 78 pupils (38 girls), mean age 14.0 ± 1.1 years. Measurements were taken in three similar Physical Education classes, on three different days. To monitor MVPA, we applied the observational momen tary time sampling method. Students wore an ActiGraph GT3X+ accelerometer. Reliabilities were determined by the intraclass correlations, the agreement between methods was analyzed using the Bland–Altman method, and a multiple regression analysis was performed to estimate the equation. The observational momentary time sampling showed good reliability across time (0.59 < r < 0.72, p < 0.001). It was significantly correlated with accelerometry (r = 0.51, p < 0.001). The MVPA assessed via accelerometer could be predicted from the following equation: Y = 44.3 + 0.47·(MVPA observa tional momentary time sampling method) + 8.0·(sex; with 0 = girls and 1 = boys). This observational momentary time sampling method is a stable and reliable tool to estimate MVPA. A regression equation using the score of observational momentary time sampling and sex can be used to better estimate the real MVPA.
- Exploring Mediation Effects of Gait Speed, Body Balance, and Falls in the Relationship between Physical Activity and Health-Related Quality of Life in Vulnerable Older AdultsPublication . Nascimento, Marcelo de Maio; Gouveia, Élvio Rúbio; Gouveia, Bruna R.; Marques, Adilson; França, Cíntia; Freitas, Duarte L.; Campos, Pedro; Ihle, AndreasThe present study aimed to examine whether gait speed (GS), body balance (BB), and falls mediated the relationship between physical activity (PA) and health-related quality of life (HRQoL) in community-dwelling older adults. This is a cross-sectional study that included 305 men and 314 women (69.5 ± 5.6 years), residing in the Autonomous Region of Madeira, Portugal. HRQoL and PA were assessed using the SF-36 and Baecke Questionnaires, respectively. While BB was obtained by the Fullerton Advance Balance (FAB) scale, GS by the 50-foot (15 m) walk test, and the frequency of falls was obtained by self-report. According to the analyses, when GS and BB were placed concomitantly as mediators, the direct effect revealed by the model revealed a non-significant relationship between PA and falls. Thus, in the context of falls, GS and BB partially mediated the association between PA and HRQoL in approximately 29.7%, 56%, and 49.2%, respectively. The total HRQoL model explained a variance of 36.4%. The results can help to understand the role that GS, BB, and falls play in the relationship between PA and HRQoL of the vulnerable older adult population.
- Exploring the Role of Physical Activity in Mediating the Association between Educational Level and Health-Related Quality of Life in an Adult Lifespan Sample from Madeira IslandPublication . García-Mayor, Jesús; Gouveia, Élvio Rúbio; Marques, Adilson; De la Cruz-Sánchez, Ernesto; Moreno-Llamas, Antonio; França, Cíntia; Gouveia, Bruna R.; Ihle, AndreasPeople more socioeconomically vulnerable tend to have a poorer health related quality of life (HRQoL). Studies are trying to analyse the factors that may condition this relationship, including physical activity (PA), which may influence the relationship between socioe conomic status (SES) and HRQoL. This study aimed to analyse the relationship between SES and HRQoL through specific domains of PA. Methods: A total of 381 adults (≥18 years) from the Au tonomous Region of Madeira completed the measurements. Mediation analyses using bootstrapping methods adjusted for confounding variables were performed to relate SES and HRQoL; the latter was evaluated using the physical component score (PCS) of the SF-12, the mental component score (MCS) of the SF-12, and the total score in the SF-12 questionnaire (SF-12 score), through physical activity. Results: Educational level was positively related to PCS and SF-12 score. Leisure-time PA (not including sports PA) and PA at work, as single mediating variables, did not mediate the relationship between SES and HRQoL. The total PA suppressed the socioeconomic gradient of HRQoL by 8–10%, 39–46%, and 15–16%, respectively, for the PCS, MCS, and the SF-12 score; sports PA mediated the relationship by 13–16%, 50%, and 15–21%, respectively. Conclusions: The results suggest that sports PA contributes to reducing the socioeconomic gradient of HRQoL.
