Do personality profiles contribute to patterns of physical activity and sedentary behavior in adulthood? A prospective cohort study.

BACKGROUND: Despite the observed associations of personality traits with levels of moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB), studies exploring whether the personality profiles differ in terms of the pattern of accumulation of physical behavior are lacking. The aim of this study was to identify adults' personality profiles and to characterize and investigate how these profiles differ in physical behavior. METHODS: The study utilized the longitudinal data of the participants of the Jyväskylä Longitudinal Study of Personality and Social Development (n = 141-307). Information on the five-factor model of personality, including the traits of neuroticism, extraversion, conscientiousness, openness, and agreeableness, was collected at ages 33, 42, 50, and 61 years, and used to create latent personality profiles. Physical behavior, operationalized as the amount and accumulation of MVPA and SB bouts, was captured using a triaxial accelerometer worn during waking hours at age 61 years. The differences in the behavior between the personality profiles were analyzed using the Kruskal-Wallis test. RESULTS: Five personality profiles were identified: resilient (20.2%), brittle (14.0%), overcontrolled (9.8%), undercontrolled (15.3%), and ordinary (40.7%). Although there were no statistically significant differences between the personality profiles in the time spent in MVPA relative to SB (MVPA per hour of daily SB), individuals with resilient (low in neuroticism and high in other traits) and ordinary (average in each trait) profiles had MVPA-to-SB ratios of 0.12 (7 min) and those with a brittle (high in neuroticism and low in extraversion) profile had a ratio of 0.09 (5.5 min). The individuals in the resilient group exhibited a longer usual MVPA bout duration than those in the overcontrolled (low in extraversion, openness, and agreeableness) (8 min vs. 2 min) and undercontrolled (high in openness and low in conscientiousness) groups (8 min vs. 3 min). They also exhibited a longer usual SB bout duration than those in the ordinary group (29 min vs. 23 min). CONCLUSIONS: The resilient group displayed the most prolonged MVPA and SB bout patterns. The results suggest that personality characteristics may contribute to how MVPA and SB are accumulated.

Social participation and mental well-being: Does purpose in life mediate the association among older adults?

OBJECTIVES: We investigated the association of social participation with mental well-being among older people and whether purpose in life mediates the potential association. METHOD: Cross-sectional (n = 1014) and longitudinal (n = 660, four-year follow-up) data comprised of three age cohorts (75, 80, and 85 years) of community-dwelling people. Life satisfaction was measured with the Satisfaction with Life Scale, depressive symptoms with the Centre for Epidemiologic Studies Depression Scale, and purpose in life with the Scales of Psychological Well-Being purpose in life subscale. Social participation was assessed with questions concerning the frequency of meeting close friends and acquaintances, and volunteering. The data were analyzed using structural equation modeling. RESULTS: Higher social participation was associated with higher life satisfaction and fewer depressive symptoms both cross-sectionally and after a four-year follow-up. Higher purpose in life mediated the associations of more social participation with higher life satisfaction and fewer depressive symptoms cross-sectionally. In the longitudinal data, the mediation effect was not observed. CONCLUSION: Older people with frequent social participation who had a sense of purpose in their lives will likely have higher mental well-being than those with less social participation. Enabling and supporting them to conduct purposeful actions in social contexts may help maintain their mental well-being.

Resiliency amid the COVID-19 pandemic: engagement in meaningful activities as a mediator between coping ability and depressive symptoms among older adults.

OBJECTIVES: This study investigated the longitudinal association between coping ability and depressive symptoms from before to during and after the COVID-19 pandemic and whether engagement in meaningful activities plays a mediating role in this association. METHOD: Individuals aged 75, 80, and 85 years (n = 1021) were interviewed in 2017-2018 (T1, pre-pandemic). Of these persons, 608 were interviewed in 2020 (T2, first wave) and 2021-2022 (T3, partly post-pandemic). Coping ability, depressive symptoms, and engagement in meaningful activities were assessed using the 10-item Connor-Davidson Resilience Scale, 10-item Center for Epidemiologic Studies Depression Scale, and 17-item activity subscore of the University of Jyväskylä Active Aging Scale, respectively. Structural equation modeling was used for the mediation analyses. RESULTS: Higher coping ability was associated with decreased depressive symptoms, partly mediated by higher activity scores between T1 and T2. From T2 to T3, higher coping ability reduced the depressive symptoms, but the activity scores did not mediate the changes during this period. CONCLUSION: Good coping ability may help older people sustain good mental well-being. With good coping ability, active engagement in meaningful activities contributed to the low level of depressiveness during the early phases of the pandemic, when many social activities were restricted.

Child socioemotional behavior and adult temperament as predictors of physical activity and sedentary behavior in late adulthood.

BACKGROUND: Most studies investigating the association of temperament with physical activity and sedentary behavior have examined children or adolescents, employed cross-sectional or longitudinal designs that do not extend from childhood into adulthood, and utilized self- or parent-reported data on physical activity and sedentary behavior. This longitudinal study investigated whether socioemotional behavior in childhood and temperament in middle adulthood predict accelerometer-measured physical activity and sedentary behavior in late adulthood. METHODS: This study was based on the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS). Socioemotional behavior (behavioral activity, well-controlled behavior, negative emotionality) was assessed at age 8 based on teacher ratings, whereas temperament (surgency, effortful control, negative affectivity, orienting sensitivity) was assessed at age 42 based on self-rating. Moderate-to-vigorous physical activity and sedentary behavior were assessed at age 61 using an accelerometer. Data (N = 142) were analyzed using linear regression analysis. RESULTS: In women, behavioral activity at age 8 predicted higher levels of daily sedentary behavior at age 61. The association did not remain statistically significant after controlling for participant's occupational status. In addition, women's negative affectivity at age 42 predicted lower daily moderate-to-vigorous physical activity at age 61, particularly during leisure time. No statistically significant results were observed in men. CONCLUSIONS: Although few weak associations of socioemotional behavior and temperament with physical activity and sedentary behavior were detected in women, they were observed over several decades, and thus, deserve attention in future studies. In addition to other factors contributing to physical activity and sedentary behavior, health professionals may be sensitive to individual characteristics, such as a tendency to experience more negative emotions, when doing health counseling or planning for health-promoting interventions targeting physical activity and sedentary behavior.

Does Personality Moderate the Efficacy of Physical and Cognitive Training Interventions? A 12-month Randomized Controlled Trial in Older Adults.

This study investigated whether personality traits moderate the effects of a 12-month physical or combined physical and cognitive training interventions on physical and cognitive functioning. Participants were community-dwelling 70-85-year-old adults (n=314). They were randomly assigned to physical training (weekly supervised walking/balance and strength/balance training, home exercises 2-3x/wk and moderate aerobic activity) or to a physical and cognitive training group (the same physical training and computer training on executive functions 3-4x/wk). The outcomes assessed at baseline and post-intervention were physical (maximum gait speed, six-minute walking distance, dual-task cost on gait speed) and cognitive functioning (Stroop, Trail-Making Test-B, verbal fluency, CERAD total score). Personality traits (NEO-PI-3, n=239) were assessed post-intervention. Personality traits did not moderate intervention effects on physical functioning. Higher openness was associated with greater improvement in CERAD scores, especially in the physical and cognitive training group (group×time×trait B=-.08, p=.038). Lower neuroticism (time×trait B=-.04, p=.021) and higher conscientiousness (time×trait B=.04, p=.027) were associated with greater improvement in CERAD scores in both groups. Personality traits had mostly null moderating effects across physical and cognitive outcomes, with the possible exception of CERAD score. Individuals with more adaptive personality traits gained more on global cognitive scores during a 12-month training intervention.

Maintenance of high quality of life as an indicator of resilience during COVID-19 social distancing among community-dwelling older adults in Finland.

PURPOSE: Social distancing during the COVID-19 pandemic reduced possibilities for activities of choice potentially threatening quality of life (QoL). We defined QoL resilience as maintaining high quality of life and studied whether walking speed, absence of loneliness, living arrangement, and stress-coping ability predict QoL resilience among older people. METHODS: Community-dwelling 75-, 80-, and 85-year-old persons (n = 685) were interviewed and examined in 2017-2018 and were followed up during COVID-19 social distancing in 2020. We assessed QoL using the OPQOL-brief scale and set a cut-off for 'constant high' based on staying in the highest baseline quartile over the follow-up and categorized all others as having 'low/moderate'. Perceived restrictiveness of the social distancing recommendations was examined with one item and was categorized as 'yes' or 'no' restrictiveness. RESULTS: Better stress-coping ability (OR 1.21, 95% CI 1.14-1.28) and not being lonely (OR 2.67, 95% CI 1.48-4.63) increased the odds for constant high QoL from before to amid social distancing, and the odds did not differ according to the perceived restrictiveness of the social distancing recommendations. Higher walking speed predicted constant high QoL only among those perceiving restrictiveness (OR 1.16, 95% CI 1.07-1.27). Living arrangement did not predict constant high QoL. CONCLUSION: During social distancing, psychosocial resources helped to maintain good QoL regardless how restrictive the social distancing recommendations were perceived to be. Better physical capacity was important for constant high QoL only among those perceiving restrictiveness presumably because it enabled replacing blocked activities with open outdoor physical activities.

Associations of neuroticism with falls in older adults: do psychological factors mediate the association?

OBJECTIVES: Neuroticism predicts falls in older people. In addition, concern about falling and depressive symptoms are associated with fall risk. This study examined whether concern about falling and depressive symptoms mediate the association between neuroticism and falls. METHOD: Cross-sectional data on 314 community-dwelling people aged 70-85 years were utilized. Neuroticism was assessed with a short modified form of the Eysenck Personality Inventory. Indoor and outdoor falls during the past year were self-reported. Concern about falling was assessed with the Falls Efficacy Scale-International and depressive symptoms with the Geriatric Depression Scale-15. Path modeling was used to examine the associations between variables. RESULTS: Mediating pathways linking neuroticism and falls were found: neuroticism was positively associated with concern about falling, which was subsequently linked to indoor falls (indirect effect ß = 0.34, p = 0.002) and recurrent outdoor falls (ß = 0.19, p = 0.045). Moreover, a pathway from neuroticism to indoor falls through depressive symptoms was also found (ß = 0.21, p = 0.054). In other words, higher neuroticism was associated with higher concern about falling and depressive symptoms, both of which were linked to falls. The associations were independent of age, sex, use of psychotropic, chronic diseases, persistent pain, physical performance, physical activity, and executive functioning that are known risk factors for falls. DISCUSSION: The results indicate that concern about falling and depressive symptoms mediate the association between neuroticism and falling. Longitudinal studies are needed to confirm the causality of the findings and to examine the potential to reduce falls by targeting concern about falling and depressive symptoms among older adults higher in neuroticism.

Associations of physical performance and physical activity with mental well-being in middle-aged women.

BACKGROUND: To investigate whether physical performance is independently of physical activity (PA) associated with positive and negative dimensions of mental well-being in middle-aged women. METHODS: Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n = 909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance). Both mental well-being (the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule Short Form and the Satisfaction with Life Scale) and PA were self-reported. Associations between variables were analysed using multivariate linear regression modelling adjusted for body height, fat mass %, menopausal status and symptoms, marital status, parity, employment status, self-reported mental disorders, and use of psycholeptics and psychoanaleptics. PA was then entered into a separate model to explore its role in the associations. RESULTS: In the adjusted models, significant positive associations of six-minute walking distance with positive affectivity (B = 0.12, p = 0.002) and life satisfaction (B = 0.15, p = 0.033) were observed. No significant associations were observed between physical performance and depressive symptoms or negative affectivity. PA was positively associated with positive affectivity and life satisfaction and negatively with depressive symptoms across all the physical performance variables. CONCLUSIONS: Of the physical performance dimensions, aerobic component was associated with positive mental well-being independently of PA level. In relation to other physical performance components, the results point to the benefits of physical activity for mental well-being.

Do opposite ends of same factors underlie life satisfaction vs. depressive symptoms among older people?

BACKGROUND: Although depressive symptoms are more common among older than younger age groups, life satisfaction tends to remain stable over the life course, possibly because the underlying factors or processes differ. AIM: To study whether the factors that increase the likelihood of high life satisfaction also decrease the likelihood of depressive symptoms among older people. METHODS: The data were a population-based probability sample drawn from community-dwelling people aged 75, 80, and 85 years (n = 1021). Participants' life satisfaction was measured with the Satisfaction with Life Scale and depressive symptoms with the Centre for Epidemiologic Studies Depression Scale (CES-D). Physical performance, perceived financial situation, executive functions, loneliness, self-acceptance, and having interests in one's life were studied as explanatory variables. The data were analyzed using cross-sectional bivariate linear modeling. RESULTS: Better physical performance, not perceiving loneliness, having special interests in one's life, and higher self-acceptance were associated with higher life satisfaction and fewer depressive symptoms. Better financial situation was related only to life satisfaction. Executive functions were not associated with either of the outcomes. DISCUSSION: The opposite ends of the same factors underlie positive and negative dimensions of mental well-being. CONCLUSION: Further studies are warranted to better understand how people maintain life satisfaction with aging when many resources may diminish and depressive symptoms become more prevalent.

Psychometric properties of the 10-item Connor-Davidson resilience scale among Finnish older adults.

OBJECTIVES: Resilience, the ability to bounce back after adverse events may be an important factor in active aging. The 10-item version of the Connor-Davidson Resilience Scale (CD-RISC10) seems suitable for aging research owing to its low participant burden; however, its psychometric properties have not been comprehensively reported for older people. For example, no estimate exists of the test-retest reliability of the scale when used with older adults. Hence, this study evaluated the psychometric properties of the CD-RISC10 in a large population-based sample of community-dwelling older people. METHOD: The scale's internal consistency, factor structure, construct validity, test-retest reliability, and user experience were analyzed among 1018 Finnish older adults (57% women) aged 75 (45%), 80 (33%) and 85 years (22%). RESULTS: The internal consistency of the CD-RISC10 was good (Cronbach's α = 0.85), test-retest reliability moderate (ICC = 0.61), and the scale was unidimensional. However, a two-factor solution was found among the 75-year-olds, where the ability to deal positively with change (e.g. using humor) explained an additional part of resilience. While no differences by gender, age, or education were observed in total scores, very good perceived financial situation was associated with higher resilience. The scale showed good construct validity, and user feedback indicated that administering the scale in research is quick and easy. CONCLUSION: In general, the CD-RISC10 is a valid method to study older adults' psychological resilience. However, the present test-retest reliability values suggest caution in using the scale as an outcome measure in intervention studies.

The Scales of Psychological Well-Being - a validation, usability and test-retest study among community-dwelling older people in Finland.

Objectives: To validate the Finnish version of the 42-item Scales of Psychological Well-Being among community-dwelling older people. The study also examined the test-retest reliability and usability, i.e. user experience, of the scales in this age group.Method: The 42-item version of the SPWB was administered as part of a face-to-face interview among 968 men and women aged 75, 80 or 85 years. The subsample for test-retest analyses comprised 42 participants, who in addition to 11 interviewers also answered questions concerning the usability of the scales. Exploratory and confirmatory factor analyses, Cronbach's alpha coefficients, Pearson and intra-class correlation coefficients, and Kendal's Tau B were used in the analyses.Results: The factor analyses did not support the theory-based six-factor structure of the scales. The Cronbach's alphas showed high internal consistency reliability for the total scale, but modest for the subscales. The intercorrelations between the subscales were moderate. The total score and the subscale scores of the SPWB correlated positively with quality of life and life satisfaction, and negatively with depressive symptoms. The interviewers reported that while most of the participants responded to the scales without marked difficulties, others could only answer after clarifications of some statements.Discussion: The reliability of the 42-item version of the SPWB was modest. The factor structure was inconsistent among the three age groups studied, but the scales were feasible to use. The current results call for further methodological consideration to optimize assessment of eudaimonic well-being in old age.

The role of personality traits in leisure time physical activity during COVID-19 pandemic.

The COVID-19 pandemic has affected everyday life, including physical activity behavior. This study examined the role of the five factor model of personality traits on leisure time physical activity during the pandemic in a sample (n = 168) of 61 year-old Finnish men and women, participating in a larger longitudinal study, between April 2020 and April 2021. Frequency of participation and changes in leisure time physical activity were self-reported. Personality traits and facets were assessed with the 181-item NEO-PI. Openness was the only factor positively associated with leisure time physical activity frequency. Participants scoring higher in extraversion (particularly the activity-facet) and lower in openness to values were more likely to report change in their physical activity. In conclusion, individual differences in traits appear to have played a role in physical activity behavior during the pandemic.

Accelerometer-measured and self-reported physical activity in relation to extraversion and neuroticism: a cross-sectional analysis of two studies.

BACKGROUND: Personality reflects relatively stable and pervasive tendencies in feeling, thinking and behaving. While previous studies have found higher extraversion and lower neuroticism to be linked to higher self-reported physical activity levels, larger studies using accelerometer-measured physical activity are lacking. This study investigated the cross-sectional associations of extraversion and neuroticism with both accelerometer-measured and self-reported physical activity and the role of these personality traits in possible discrepancies between these two measures of physical activity among Finnish adults. METHODS: Two community-dwelling samples were used in this study: a) 47-55-yr-old women (n = 1098) and b) 70-85-yr-old women and men (n = 314). In both samples, extraversion and neuroticism were assessed by the 19-item short form of the Eysenck Personality Inventory. Physical activity was assessed with hip-worn tri-axial accelerometers and self-reported questions. Regression analyses were adjusted by age, BMI and education. RESULTS: In the middle-aged women, neuroticism was negatively associated with accelerometer-measured leisure time moderate-to-vigorous physical activity (ß = -.07, p = .036) and with self-reported physical activity (ß = -.08, p = .021), while extraversion was positively associated with self-reported physical activity (ß = .10, p = .005). No associations of extraversion or neuroticism with physical activity were found in the older men and women. Older adults who scored high in neuroticism reported less physical activity than what was measured by accelerometers (ß = -.12, p = .039). Extraversion was not associated with discrepancy between self-reported and accelerometer-measured leisure time physical activity in either sample. CONCLUSIONS: Neuroticism was associated with lower leisure-time physical activity levels and extraversion with higher self-reported physical activity among middle-aged women. Neuroticism and extraversion were unrelated to physical activity among older adults, but older adults with high neuroticism seemed to underreport their physical activity level. The role of personality in the discrepancy between self-reported and device-based physical activity warrants further research.

The effect of individualized, theory-based counselling intervention on active aging and quality of life among older people (the AGNES intervention study).

BACKGROUND: We define active aging as a striving for activities as per one's goals, capacities and opportunities. AIM: To test the 1-year counselling intervention effects on active aging. METHODS: In this two-arm single-blinded randomized controlled trial, the intervention group received individually tailored counselling supporting autonomous motivation for active life (one face-to-face session, four phone calls and supportive written material, n = 101) and the control group written health information (n = 103). Participants were community-dwelling men and women aged 75 or 80 years with intermediate mobility function and without cognitive impairment. The primary outcome was active aging total score measured with the University of Jyväskylä Active Aging Scale (UJACAS, range 0-272, higher values indicate more activity) and secondary outcomes were its subscores for goals, ability, opportunity and activity (range 0-68) and a quality of life (QoL) score. Measures took place at pre-trial, mid-trial (6 months) and post-trial (12 months), except for QoL only pre and post-trial. Data were analyzed with intention-to-treat principles using GEE-models. RESULTS: The UJACAS total score increased in the intervention group slightly more than in the control group (group by time p-value = 0.050, effect size 0.011, net benefit 2%), but the group effect was not statistically significant. A small effect was observed for the activity subscore (p = 0.007). DISCUSSION: The individualized counselling supporting autonomous motivation for active life increased the UJACAS score slightly. CONCLUSIONS: It may be possible to promote active aging with individualized counselling, but the effect is small and it is unclear whether the change is meaningful.

Association of childhood adversities and home atmosphere with functioning in old age: the Helsinki birth cohort study.

Objective: childhood adversities have been linked with adverse health outcomes, but less is known about the long-term consequences of childhood home atmosphere. We investigated whether childhood adversities and home atmosphere were associated with physical and mental functioning in older age. Methods: in the Helsinki Birth Cohort Study 2003, participants born in the year 1934-44 had data available on nine childhood home atmosphere items, e.g. whether it was supportive and warm (sum score ranged between 0 and 36, higher score indicating better atmosphere), and nine childhood adversities, e.g. unemployment and divorce (sum score 0-9, coded into no; one; and two or more adversities) assessed in 2001-04. Of those, 835 had data on physical and mental functioning assessed using the Short Form 36 questionnaire in 2011-13. Results: those who had experienced two or more childhood adversities were more likely to have poorer physical and mental functioning in older age compared to those with no adversities. A better home atmosphere score was associated with better mental functioning (per one unit higher score ß 0.24, 95% CI 0.16-0.32, P < 0.001). In models including both childhood adversities and home atmosphere, a more favourable home atmosphere was associated with better mental functioning while the association for childhood adversities attenuated. There were no associations between childhood adversities or home atmosphere and physical functioning in the models that included both childhood exposures. Conclusions: childhood adversities and home atmosphere have long-term associations with physical and mental functioning in older age.

Individualized counselling for active aging: protocol of a single-blinded, randomized controlled trial among older people (the AGNES intervention study).

BACKGROUND: Active aging has been established as a policy goal for aging societies. We define active aging at the individual level as striving for elements of well-being through activities in relation to a person's goals, functional capacities and opportunities. Increasing evidence suggests that any meaningful activity is beneficial for different aspects of well-being in older people. The aim of the present randomized controlled trial is to test the feasibility and effectiveness of a one-year community-based intervention on active aging. The AGNES intervention aims at increasing older peoples' participation in self-selected valued activities. METHODS: The proposed study is a two-arm single-blinded randomized controlled trial. The intervention group receives individually tailored counselling for an active life (one face-to-face session, four phone calls and supportive written material) and the control group written general health information only. Two hundred older adults aged 75- and 80- year old, with intermediate mobility function and without cognitive impairment, living independently in the municipality of Jyväskylä, Finland, are recruited and randomized with a 1:1 allocation to the intervention and control group. Randomization is computer-generated stratified by sex and age. The primary outcome is active aging and secondary outcomes are well-being, depressive symptoms, quality of life, personal goals, mobility and physical activity. Measures are administered at pre-trial, mid-trial (at 6 months) and post-trial (12 months after baseline). DISCUSSION: The AGNES intervention study will provide new knowledge on the effects of individualized counselling on active aging and the potential of older people to promote their own well-being. TRIAL REGISTRATION: The trial is registered at ISRCTN - ISRCTN16172390 : Promoting well-being through active aging.

Cardiac Rehabilitees' Technology Experiences Before Remote Rehabilitation: Qualitative Study Using a Grounded Theory Approach.

BACKGROUND: Even though technology is becoming increasingly common in rehabilitation programs, insufficient data are as yet available on rehabilitees' perceptions and experiences. It is important to understand their abilities when using technology for remote rehabilitation. OBJECTIVE: This is a qualitative study on technology experiences of persons affected by cardiovascular disease assessed before remote rehabilitation. The aim of the study was to explore rehabilitees' experiences and attitudes toward technology before 12 months of remote rehabilitation. METHODS: Qualitative interviews were conducted with 39 rehabilitees in four focus groups. The subjects were aged 34 to 77 years (average age 54.8 years) and 74% (29/39) of them were male. They had been diagnosed with coronary artery disease and were undergoing treatment in a rehabilitation center. The interviews were conducted between September 2015 and November 2016. Data were analyzed using Glaser's mode of the grounded theory approach. RESULTS: The result of the study was an "identifying e-usage" experience category, which refers to the rehabilitees' notions of the use of information and communication technologies (e-usage) in the process of behavior change. The main category comprises four subcategories that define the rehabilitees' technology experience. These subcategories are "feeling outsider," "being uninterested," "reflecting benefit," and "enthusiastic using." All rehabilitees expected that technology should be simple, flexible, and easy to use and learn. The results reflecting their technology experience can be used in e-rehabilitation programs. Rehabilitees who feel like outsiders and are not interested in technology need face-to-face communication for the major part of rehabilitation, while rehabilitees who reflect benefit and are enthusiastic about the use of technology need incrementally less face-to-face interaction and feel that Web-based coaching could offer sufficient support for rehabilitation. CONCLUSIONS: The findings show that persons affected by heart disease had different experiences with technology and expectations toward counseling, while all rehabilitees expected technology to be easy to use and their experiences to be smooth and problem-free. The results can be used more widely in different contexts of social and health care for the planning of and training in remote rehabilitation counseling and education.

Effects of a 9-month resistance training intervention on quality of life, sense of coherence, and depressive symptoms in older adults: randomized controlled trial.

PURPOSE: (1) To determine the effects of a 9-month resistance training intervention on quality of life, sense of coherence, and depressive symptoms in older adults, and (2) to compare effects between different training frequencies. METHODS: Men and women aged 65-75 (N = 106) were randomized to four groups according to training frequency: training groups RT1 (n = 26), RT2 (n = 27), and RT3 (n = 28) and non-training control group (n = 25). All training groups attended supervised resistance training twice a week for 3 months. For the following 6 months, they continued training with different frequencies (1, 2 or 3 times per week). Psychological functioning was measured by quality of life (WHOQOL-Bref), sense of coherence (Antonovsky's SOC-13), and depressive symptoms (Beck's Depression Inventory II). Measurements were conducted at baseline and 3 and 9 months after baseline. The effects of the intervention were analyzed using generalized estimating equations (GEE). RESULTS: After 3 months, there was an intervention effect on environmental quality of life (group × time p = .048). Between 3 and 9 months, environmental quality of life decreased among RT1 compared to RT2 and RT3 (group × time p = .025). Between baseline and 9 months, environmental quality of life increased in RT2 compared to all other groups (group × time p = .011). Sense of coherence increased in RT2 compared to the control group and RT3 (group × time p = .032). CONCLUSION: Resistance training is beneficial for environmental quality of life and sense of coherence. Attending resistance training twice a week seems to be the most advantageous for these aspects of psychological functioning.

Promoting safe walking among older people: the effects of a physical and cognitive training intervention vs. physical training alone on mobility and falls among older community-dwelling men and women (the PASSWORD study): design and methods of a randomized controlled trial.

BACKGROUND: Safe and stable walking is a complex process involving the interaction of neuromuscular, sensory and cognitive functions. As physical and cognitive functions deteriorate with ageing, training of both functions may have more beneficial effects on walking and falls prevention than either alone. This article describes the study design, recruitment strategies and interventions of the PASSWORD study investigating whether a combination of physical and cognitive training (PTCT) has greater effects on walking speed, dual-task cost in walking speed, fall incidence and executive functions compared to physical training (PT) alone among 70-85-year-old community-dwelling sedentary or at most moderately physically active men and women. METHODS: Community-dwelling sedentary or at most moderately physically active, men and women living in the city of Jyväskylä will be recruited and randomized into physical training (PT) and physical and cognitive training (PTCT). The 12-month interventions include supervised training sessions and home exercises. Both groups attend physical training intervention, which follows the current physical activity guidelines. The PTCT group performes also a web-based computer program targeting executive functions. Outcomes will be assessed at baseline and at 6 and 12 months thereafter. Falls data are collected during the interventions and the subsequent one-year follow-up. The primary outcome is 10-m walking speed. Secondary outcomes include 6-min walking distance, dual-task cost in walking speed, fall incidence and executive function assessed with color Stroop and Trail Making A and B tests. Explanatory outcomes include e.g. body composition and bone characteristics, physical performance, physical activity, life-space mobility, fall-related self-efficacy, emotional well-being and personality characteristics. DISCUSSION: The study is designed to capture the additive and possible synergistic effects of physical and cognitive training. When completed, the study will provide new knowledge on the effects of physical and cognitive training on the prevention of walking limitations and rate of falls in older people. The expected results will be of value in informing strategies designed to promote safe walking among older people and may have a significant health and socio-economic impact.

Active aging - resilience and external support as modifiers of the disablement outcome: AGNES cohort study protocol.

BACKGROUND: Population aging increases the need for knowledge on positive aspects of aging, and contributions of older people to their own wellbeing and that of others. We defined active aging as an individual's striving for elements of wellbeing with activities as per their goals, abilities and opportunities. This study examines associations of health, health behaviors, health literacy and functional abilities, environmental and social support with active aging and wellbeing. We will develop and validate assessment methods for physical activity and physical resilience suitable for research on older people, and examine their associations with active aging and wellbeing. We will examine cohort effects on functional phenotypes underlying active aging and disability. METHODS: For this population-based study, we plan to recruit 1000 participants aged 75, 80 or 85 years living in central Finland, by drawing personal details from the population register. Participants are interviewed on active aging, wellbeing, disability, environmental and social support, mobility, health behavior and health literacy. Physical activity and heart rate are monitored for 7 days with wearable sensors. Functional tests include hearing, vision, muscle strength, reaction time, exercise tolerance, mobility, and cognitive performance. Clinical examination by a nurse and physician includes an electrocardiogram, tests of blood pressure, orthostatic regulation, arterial stiffness, and lung function, as well as a review of chronic and acute conditions and prescribed medications. C-reactive protein, small blood count, cholesterol and vitamin D are analyzed from blood samples. Associations of factors potentially underlying active aging and wellbeing will be studied using multivariate methods. Cohort effects will be studied by comparing test results of physical and cognitive functioning with results of a cohort examined in 1989-90. CONCLUSIONS: The current study will renew research on positive gerontology through the novel approach to active aging and by suggesting new biomarkers of resilience and active aging. Therefore, high interdisciplinary impact is expected. This cross-sectional study will not provide knowledge on temporal order of events or causality, but an innovative cross-sectional dataset provides opportunities for emergence of novel creative hypotheses and theories.
