Health-related quality of life after hip fracture: effects of a 12-month home-based exercise intervention-secondary analyses of an RCT.

PURPOSE: In this randomized controlled trial, we analyzed the effects of a 12-month home-based exercise intervention on the health-related quality of life (HRQoL) of patients with a hip fracture. METHODS: Participants (n = 121) aged ≥ 60 years, with a Mini-Mental State Examination (MMSE) score of ≥ 12 and an operated hip fracture, were placed into Exercise (n = 61) or Usual care (n = 60) groups. Physiotherapist-supervised, home-based training was given twice a week over 12 months. HRQoL was assessed using the 15D instrument at baseline and at 3, 6, and 12 months. The total 15D scores and dimension scores were analyzed and compared to national age- and sex-matched reference data. RESULTS: The participants' mean age was 81 years (SD 7), 75% were women, and 61% had a femoral neck fracture. The mean within-group change in total 15D score over 12 months was 0.023 (95% CI: -0.003 to 0.048) in the Usual care group, and 0.028 (CI: 0.003 to 0.054) in the Exercise group (between-group p = 0.76). We found a statistically significant change in total 15D score in the Exercise group, as well as in the dimension scores of mobility and usual activities in both groups. All 15D scores remained below the general population reference level. CONCLUSION: Exercise training for 12 months did not enhance the HRQoL of home-dwelling patients with hip fractures any more than usual care. In addition, HRQoL remained below the population level in both groups.

Low physical activity is a risk factor for sarcopenia: a cross-sectional analysis of two exercise trials on community-dwelling older adults.

BACKGROUND: Physical inactivity is an important factor in the development of sarcopenia. This cross-sectional study explores the prevalence of sarcopenia and associations of physical activity (PA) with sarcopenia in two exercise trial populations. These study groups are clinically meaningful community-dwelling populations at increased risk for sarcopenia: older adults not meeting the PA guidelines and those with a recent hip fracture (HF). METHODS: Data from 313 older adults who did not meet the PA guidelines (60% women; age 74.5 ± 3.8, body mass index 27.9 ± 4.7) and 77 individuals with HF diagnosed on average 70 ± 28 days earlier (75% women; age 79.3 ± 7.1, body mass index 25.3 ± 3.6) were included in this study. Grip strength and muscle mass (Dual-energy X-ray absorptiometry [DXA] in older adults not meeting the PA guidelines and bioimpedance analysis in participants with HF) were used to assess sarcopenia according to the European Working Group in Older People 2019 (EWGSOP2) criteria. The current level of PA was self-reported using a question with seven response options in both study groups and was measured with a hip-worn accelerometer for seven consecutive days in older adults not meeting the PA guidelines. RESULTS: The prevalence of sarcopenia and probable sarcopenia was 3% (n = 8) and 13% (n = 41) in the older adults not meeting the PA guidelines and 3% (n = 2) and 40% (n = 31) in the HF group, respectively. In the age- and sex-adjusted logistic regression model, the lowest levels of self-reported PA were associated with increased probable sarcopenia and sarcopenia risk in older adults not meeting the PA guidelines (OR 2.8, 95% CI, 1.3-6.1, p = 0.009) and in the HF group (OR 3.9, 95% CI, 1.4-11.3, p = 0.012). No significant associations between accelerometer-measured PA and probable sarcopenia or sarcopenia were found. CONCLUSIONS: Probable sarcopenia is common among community-dwelling older adults not meeting the PA guidelines and very common among individuals recovering from HF who are able to be involved in exercise interventions. In addition, since low PA is associated with higher probable sarcopenia and sarcopenia risk, it is recommended to screen for sarcopenia and promote regular physical activity to prevent sarcopenia in these populations.

Two-week step-reduction has limited negative effects on physical function and metabolic health in older adults.

PURPOSE: This study determined the effects of a 2-week step-reduction period followed by 4-week exercise rehabilitation on physical function, body composition, and metabolic health in 70-80-year-olds asymptomatic for injury/illness. METHODS: A parallel-group randomized controlled trial (ENDURE-study, NCT04997447) was used, where 66 older adults (79% female) were randomized to either intervention or control group. The intervention group reduced daily steps to < 2000, monitored by accelerometer, for two weeks (Period I) and then step-reduction requirement was removed with an additional exercise rehabilitation 4 times per week for 4 weeks (Period II). The control group continued their habitual physical activity throughout with no additional exercise intervention. Laboratory tests were performed at baseline, after Period I and Period II. The primary outcome measure was leg lean mass (LLM). Secondary outcomes included total lean and fat mass, blood glucose and insulin concentration, LDL cholesterol and HDL cholesterol concentration, maximal isometric leg press force (MVC), and chair rise and stair climb performance. RESULTS: LLM remained unchanged in both groups and no changes occurred in physical function nor body composition in the intervention group in Period I. HDL cholesterol concentration reduced after Period I (from 1.62 ± 0.37 to 1.55 ± 0.36 mmol·L-1, P = 0.017) and returned to baseline after Period II (1.66 ± 0.38 mmol·L-1) in the intervention group (Time × Group interaction: P = 0.065). MVC improved after Period II only (Time × Group interaction: P = 0.009, Δ% = 15%, P < 0.001). CONCLUSION: Short-term step-reduction in healthy older adults may not be as detrimental to health or physical function as currently thought.

The Impact of Multimorbidity Patterns on Changes in Physical Activity and Physical Capacity Among Older Adults Participating in a Year-Long Exercise Intervention.

This study investigated the impact of multimorbidity patterns on physical activity and capacity outcomes over the course of a year-long exercise intervention, and on physical activity 1 year later. Participants were 314 physically inactive community-dwelling men and women aged 70-85 years, with no contraindications for exercise at baseline. Physical activity was self-reported. Physical capacity measurements included five-time chair-stand time, 6-minute walking distance, and maximal isometric knee-extension strength. The intervention included supervised and home-based strength, balance, and walking exercises. Multimorbidity patterns comprised physician-diagnosed chronic disease conditions as a predictor cluster and body mass index as a measure of obesity. Multimorbidity patterns explained 0%-12% of baseline variance and 0%-3% of the change in outcomes. The magnitude and direction of the impact of unique conditions varied by outcome, time point, and sex. Multimorbid older adults with no contraindications for exercise may benefit from multimodal physical training.

Early adulthood and current physical activity and their association with symptoms of pelvic floor disorders in middle-aged women: An observational study with retrospective physical activity assessment.

OBJECTIVE: To investigate associations of early and middle adulthood physical activity (PA) with symptoms of pelvic floor disorders (PFDs), i.e. stress urinary incontinence (SUI), urge urinary incontinence (UUI), faecal incontinence (FI), constipation or defecation difficulties (CDDs) and feeling of pelvic organ prolapse (POP) among middle-aged women. DESIGN: A cross-sectional, observational study with retrospective PA assessment. SETTING: University Research Laboratory. SAMPLE: A random population sample of 1098 Finnish women aged 47-55 years. METHODS: Early adulthood PA, current PA, and demographic and gynaecological variables were assessed using self-report questionnaires. Logistic regression analyses were applied to study associations of PA variables with symptoms of PFDs. Potential confounding effects of demographic and gynaecological variables were controlled in multiple logistic regression models. MAIN OUTCOME MEASURES: Structured questionnaire-assessed retrospective PA assessment at the age of 17-29 years, current PA at middle age, and prevalence of symptoms of CDD, FI, POP, SUI and UUI. RESULTS: Current PA was not independently associated with the occurrence of the symptoms of PFDs. Middle-aged women with an early adulthood history of competitive sports were more likely to experience symptoms of UUI (OR 2.16, 95% CI 1.10-4.24, p = 0.025) but not symptoms of SUI, FI, CDD or POP, whereas women with a history of regular PA were more likely to experience symptoms of FI (OR 4.41, 95% CI 1.05-18.49, p = 0.043) but no other symptoms of PFDs. CONCLUSIONS: Competitive sports during early adulthood may increase the risk of UUI in middle age. Regular PA during early adulthood may increase the risk of FI.

Beta-band MEG signal power changes in older adults after physical exercise program with and without additional cognitive training.

Physical exercise has been considered to be an efficient mean of preserving cognitive function and it influences both the structural and functional characteristics of the brain. It has especially been shown to increase brain plasticity, the capacity to re-structure brain properties in response to interaction, such as cognitive practice. Studies have also examined the potential additive effect of cognitive training on the documented benefit of physical exercise, commonly, however, not at the neural level. We monitored, using magnetoencephalography (MEG), the brain processes associated with executive functions in older individuals who participated in a 12-month randomized controlled trial including two research arms: physical and cognitive training vs physical training alone. Measurements were conducted at 0 months, 6 months, and 12 months. The addition of cognitive training was associated with better performance in the Stroop test that reflects executive control. The extra benefit of cognitive training was also manifested as decreased modulation of beta frequency band (15-25 Hz) especially to difficult distractors. As beta band activity is associated with attentional control, this indicates fewer resources needed to inhibit irrelevant sensory inputs. These results imply an enhancing role of cognitive elements integrated with physical training in improving or maintaining executive functions in older individuals.

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.

Metabolic health, menopause, and physical activity-a 4-year follow-up study.

BACKGROUND: In women, metabolic health deteriorates after menopause, and the role of physical activity (PA) in mitigating the change is not completely understood. This study investigates the changes in indicators of metabolic health around menopause and evaluates whether PA modulates these changes. METHODS: Longitudinal data of 298 women aged 48-55 years at baseline participating in the ERMA and EsmiRs studies was used. Mean follow-up time was 3.8 (SD 0.1) years. Studied indicators of metabolic health were total and android fat mass, waist circumference, waist-to-hip ratio (WHR), systolic (SBP) and diastolic (DBP) blood pressure, blood glucose, triglycerides, serum total cholesterol, and high- (HDL-C) and low-density (LDL-C) lipoprotein cholesterol. PA was assessed by accelerometers and questionnaires. The participants were categorized into three menopausal groups: PRE-PRE (pre- or perimenopausal at both timepoints, n = 56), PRE-POST (pre- or perimenopausal at baseline, postmenopausal at follow-up, n = 149), and POST-POST (postmenopausal at both timepoints, n = 93). Analyses were carried out using linear and Poisson mixed-effect models. RESULTS: At baseline, PA associated directly with HDL-C and inversely with LDL-C and all body adiposity variables. An increase was observed in total (B = 1.72, 95% CI [0.16, 3.28]) and android fat mass (0.26, [0.06, 0.46]), SBP (9.37, [3.34, 15.39]), and in all blood-based biomarkers in the PRE-POST group during the follow-up. The increase tended to be smaller in the PRE-PRE and POST-POST groups compared to the PRE-POST group, except for SBP. The change in PA associated inversely with the change in SBP (-2.40, [-4.34, -0.46]) and directly with the change in WHR (0.72, [0.05, 1.38]). CONCLUSIONS: In middle-aged women, menopause may accelerate the changes in multiple indicators of metabolic health. PA associates with healthier blood lipid profile and body composition in middle-aged women but does not seem to modulate the changes in most of the studied metabolic health indicators during the menopausal transition.

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 Between Physical and Executive Functions Among Community-Dwelling Older Men and Women.

Walking is a complex task requiring the interplay of neuromuscular, sensory, and cognitive functions. Owing to the age-related decline in cognitive and physical functions, walking may be compromised in older adults, for cognitive functions, especially poor performance in executive functions, is associated with slow walking speed. Hence, the aim of this study was to investigate the associations between different subdomains of executive functions and physical functions and whether the associations found differ between men and women. Multiple linear regression analysis was performed on data collected from 314 community-dwelling older adults who did not meet physical activity guidelines but had intact cognition. Our results showed that, while executive functions were associated with gait and lower extremity functioning, the associations depended partly on the executive process measured and the nature of the physical task. Moreover, the associations did not differ between the sexes.

Perimenopausal women show modulation of excitatory and inhibitory neuromuscular mechanisms.

BACKGROUND: Menopausal transition exposes women to an early decline in muscle force and motor function. Changes in muscle quality and function, especially in lower limbs, are crucial, as they expose individuals to increased risk of falls. To elucidate some of the related neuromuscular mechanisms, we investigated cortical inhibition and peripheral muscle twitch force potentiation in women during the early and late stages of perimenopause. METHODS: Participants were 63 women aged 48-55 years categorized as early (EP, n = 25) or late (LP, n = 38) perimenopausal according to serum follicle-stimulating hormone (FSH) levels and menstrual diaries. EP women had an irregular menstrual cycle and FSH < 25 IU/L, while LP women had an irregular cycle and > 25 IU/L. We examined motor evoked potential (MEP) and silent period (SP) elicited by transcranial magnetic stimulation (TMS), in the tibialis anterior muscle at 20%, 40%, and 60% of maximal voluntary contraction (MVC) levels, and twitch force potentiation in plantar flexors. RESULTS: EP group showed a longer SP duration in 40% MVC condition and larger motor evoked potential amplitude in 20% MVC condition compared to the LP group. No group difference was detected in twitch force potentiation; however, it correlated negatively with FSH levels. Other factors, such as age, height, body mass index, or physical activity did not explain group differences. CONCLUSIONS: Our preliminary results indicate subtle modulation in both TMS-induced inhibitory and excitatory mechanisms and twitch force potentiation in women already in the late perimenopausal stage. This suggests that the reduction of estrogens may have an accelerating role in the aging process of neuromuscular control.

Effect of 12-Month Supervised, Home-Based Physical Exercise on Functioning Among Persons With Signs of Frailty: A Randomized Controlled Trial.

OBJECTIVES: To investigate the effects of a 12-month home-based exercise program on functioning and falls among persons with signs of frailty. DESIGN: A randomized controlled trial with a 1:1 allocation. SETTING: Home-based. PARTICIPANTS: Home-dwelling persons aged 65 years or older meeting at least 1 frailty phenotype criteria (N=300). The mean age of the participants was 82.2±6.3 years, 75% were women, 61% met 1-2 frailty criteria, and 39% met ≥3 criteria. INTERVENTIONS: A 12-month, individually tailored, progressive, and physiotherapist-supervised physical exercise twice a week (n=150) vs usual care (n=149). MAIN OUTCOME MEASURES: FIM, Short Physical Performance Battery (SPPB), handgrip strength, instrumental activities of daily living (IADL), and self-reported falls and physical activity (other than intervention). Assessed 4 times at home over 12 months. RESULTS: FIM deteriorated in both groups over 12 months, -4.1 points (95% confidence interval [CI], -5.6 to -2.5) in the exercise group and -6.9 (95% CI, -8.4 to -2.3) in the usual care group (group P=.014, time P<.001, interaction P=.56). The mean improvement in SPPB was significantly greater in the exercise group (1.6 [95% CI, 1.3-2.0]) than in the usual care group (0.01 [95% CI, -0.3 to 0.3]) (group P<.001, time P=.11, interaction P=.027). The exercise group reported significantly fewer falls per person-year than the usual care group (incidence rate ratio, 0.47 [95% CI, 0.40-0.55]; P<.001). There was no significant difference between the groups over 12 months in terms of handgrip strength, IADL function, or self-reported physical activity. CONCLUSIONS: One year of physical exercise improved physical performance and decreased the number of falls among people with signs of frailty. FIM differed between the groups at 12 months, but exercise did not prevent deterioration of FIM, IADL, or handgrip strength.

Effects of Home-Based Physical Exercise on Days at Home, Health Care Utilization, and Functional Independence Among Patients With Hip Fractures: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effects of a physical exercise program on days lived at home, the use and costs of health care and social services, mortality, and functional independence among patients with hip fractures. DESIGN: Randomized controlled trial with a parallel 2-group design consisting of a 12-month intervention and 12-month registry follow-up. SETTING: Home-based intervention. PARTICIPANTS: Patients aged ≥60 years (N=121) with operated hip fracture and who were living at home were randomized into physical exercise (n=61) and usual care (n=60) groups. INTERVENTIONS: Supervised physical exercise twice a week. MAIN OUTCOME MEASURES: The primary outcome was the number of days lived at home over 24 months. Secondary outcomes were the use and costs of health care and social services, mortality over 24 months, and Functional Independence Measure (FIM) over 12 months. RESULTS: Over 24 months, there was no significant difference between the groups in terms of days lived at home (incidence rate ratio, 1.01; 95% confidence interval [CI], 0.90-1.14) or mortality (hazard ratio, 1.01; 95% CI, 0.42-2.43). The mean total costs of health care and social services did not differ between the groups. The costs per person-year were 1.26-fold (95% CI, 0.87-1.86) greater in the physical exercise group than in the usual care group over 12 months and 1.08-fold (95% CI, 0.77-1.70) over 24 months. The mean difference between the change in FIM of the groups over 12 months was 4.5 points (95% CI, 0.5-8.5; P=.029) in favor of the physical exercise group. CONCLUSIONS: Long-term home-based physical exercise had no effect on the number of days lived at home over 24 months among patients with hip fractures. The intervention was cost neutral over these 24 months. The FIM scores improved in both groups over 12 months, but the improvement was significantly greater in the physical exercise group than in the usual care group.

Effects of physical and cognitive training on gait speed and cognition in older adults: A randomized controlled trial.

Gait speed is a measure of health and functioning. Physical and cognitive determinants of gait are amenable to interventions, but best practices remain unclear. We investigated the effects of a 12-month physical and cognitive training (PTCT) on gait speed, dual-task cost in gait speed, and executive functions (EFs) compared with physical training (PT) (ISRCTN52388040). Community-dwelling older adults, who did not meet physical activity recommendations, were recruited (n = 314). PT included supervised walking/balance (once weekly) and resistance/balance training (once weekly), home exercises (2-3 times weekly), and moderate aerobic activity 150 min/week in bouts of >10 min. PTCT included the PT and computer training (CT) on EFs 15-20 min, 3-4 times weekly. The primary outcome was gait speed. Secondary outcomes were 6-min walking distance, dual-task cost in gait speed, and EF (Stroop and Trail Making B-A). The trial was completed by 93% of the participants (age 74.5 [SD3.8] years; 60% women). Mean adherence to supervised sessions was 59%-72% in PT and 62%-77% in PTCT. Home exercises and CT were performed on average 1.9 times/week. Weekly minutes spent in aerobic activities were 188 (median 169) in PT and 207 (median 180) in PTCT. No significant interactions were observed for gait speed (PTCT-PT, 0.02; 95%CI -0.03, 0.08), walking distance (-3.8; -16.9, 9.3) or dual-task cost (-0.22; -1.74, 1.30). Stroop improvement was greater after PTCT than PT (-6.9; -13.0, -0.8). Complementing physical training with EFs training is not essential for promotion of gait speed. For EF's, complementing physical training with targeted cognitive training provides additional benefit.

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.

Birth cohort differences in cognitive performance in 75- and 80-year-olds: a comparison of two cohorts over 28 years.

OBJECTIVE: To evaluate cohort differences in cognitive performance in older men and women born and assessed 28 years apart. METHODS: Data in this study were drawn from two age-homogeneous cohorts measured in the same laboratory using the same standardized cognitive performance tests. Participants in the first cohort were born in 1910 and 1914 and assessed in 1989-1990 (Evergreen project, n = 500). Participants in the second cohort were born in 1938 or 1939 and 1942 or 1943 and assessed in 2017-2018 (Evergreen II, n = 726). Participants in both cohorts were assessed at age 75 and 80 years and were recruited from the population register. Cognitive performance was measured using the Digit Span test from the Wechsler Memory Scale (WMS), Digit Symbol test from the Wechsler Adult Intelligence Scale (WAIS) and phonemic Verbal Fluency test from the Schaie-Thurstone Adult Mental Abilities Test. Reaction time assessing motor and mental responses was measured with a simple finger movement task, followed by a complex finger movement task. T-tests were used to study cohort differences and linear regression models to study possible factors underlying differences. RESULTS: We found statistically significant cohort differences in all the cognitive performance tests, except for the digit span test and simple movement task in men, the later-born cohort performing better in all the measured outcomes. CONCLUSIONS: The results of this study provide strong evidence that cognitive performance is better in more recent cohorts of older people compared to their counterparts measured 28 years earlier.

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.

Effects of an individually targeted multicomponent counseling and home-based rehabilitation program on physical activity and mobility in community-dwelling older people after discharge from hospital: a randomized controlled trial.

OBJECTIVES: The aim of this study is to evaluate the effects of multicomponent rehabilitation on physical activity, sedentary behavior, and mobility in older people recently discharged from hospital. DESIGN: Randomized controlled trial. SETTING: Home and community. PARTICIPANTS: Community-dwelling people aged ⩾60 years recovering from a lower limb or back musculoskeletal injury, surgery, or disorder were recruited from local health center hospitals and randomly assigned into an intervention (n = 59) or a control (standard care, n = 58) group. INTERVENTION: The six-month intervention consisted of a motivational interview, goal attainment process, guidance for safe walking, a progressive home exercise program, physical activity counseling, and standard care. MEASUREMENTS: Physical activity and sedentary time were assessed using an accelerometer and a single question. Mobility was evaluated with the Short Physical Performance Battery, self-reported use of a walking aid, and ability to negotiate stairs and walk outdoors. Intervention effects were analyzed with generalized estimating equations. RESULTS: Daily physical activity was 127 ± 78 minutes/day and 121 ± 70 at baseline and 167 ± 81 and 164 ± 72 at six months in the intervention and control group, respectively; mean difference of 3.4 minutes (95% confidence interval (CI) = -20.3 to 27.1). In addition, no significant between-group differences were shown in physical performance. CONCLUSION: The rehabilitation program was not superior to standard care for increasing physical activity or improving physical performance. Mobility-limited older people who had recently returned home from hospital would have needed a longer and more frequently monitored comprehensive geriatric intervention.

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.
