Psychosocial correlates of flourishing in the late lifespan.

BACKGROUND: Flourishing is a primary dimension of psychological well-being that contributes massively to the development of an active, purposeful, and respectful life, full of meaning, values, and personal interests that nurture social ties. AIMS: This study primarily intended to examine the contribution of satisfaction with family relations, resilience, metacognitive efficiency, and crystallized intelligence in predicting a flourishing measure in cognitively healthy older adults. Moreover, the impact of gender was investigated on flourishing, satisfaction with family ties, resilience, and metacognitive efficiency. METHODS: One hundred and eighty 65-94-year-old community dwellers were recruited in Sardinia (Italy). Participants self-rated their flourishing, satisfaction with their family connections, psychological hardness (i.e., a dimension of resilience), and cognitive function, whereas global cognitive efficiency and vocabulary were assessed through two internationally validated objective tests. RESULTS: A hierarchical regression analysis revealed that 30% of the variance in the flourishing condition was explained by satisfaction with family ties, resilience, and metacognitive efficiency. In addition, males exhibited higher flourishing and satisfaction with family ties than females, and the former group also reported being more autonomous and acting proactively to influence its destiny. CONCLUSION: Emotional support and rewarding relations with family members, the ability to face stressful events, and a good perception of one's cognitive efficiency play a crucial role in promoting flourishing in late adulthood.

Cognitive Reserve, Physical Reserve, and Cognitive Efficiency of Older People Living in the Sardinian Blue Zone. An Exploratory Study.

This study mainly intended to disentangle the role played by physical reserve as a mediator of the relationship between cognitive reserve and global cognitive functioning in older people aging well. A sample of 120 67-101-year-old community-dwellers was recruited in the Sardinian Blue Zone, an area characterized by the extreme longevity of its inhabitants. Each respondent completed a battery of tests examining cognitive functioning, perceived physical health, cognitive reserve, and physical reserve (objectively assessed through accelerometric-derived measures). Significant associations were found among measures of cognitive reserve, physical reserve, perceived physical health, and cognition. Besides, two mediational analyses pointed out that physical reserve and distinct indexes of cognitive reserve explained 18% and 32% of the variance associated with global cognitive functioning. In conclusion, the combination of high cognitive reserve and more preserved motor functioning seems to contribute to the maintenance of healthy cognition in older people aging well.

Is Cognitive Reserve a Determinant of Functional and Mental Health in Older People of the Sardinian Blue Zone? A Mediational Approach.

The main purpose of this study was to examine the mediating role of cognitive reserve in the relationship between functional health (expressed through the amount and intensity of performed physical activity objectively assessed using wearable accelerometers) and psychological well-being (i.e., assessed in terms of self-reported depressive signs) of older people living in an area of exceptional longevity, the so-called Sardinian Blue Zone. A further goal was to investigate the impact of gender on the cognitive reserve and physical health of our participants, using global cognitive functioning as a covariate. A battery of tests assessing motor efficiency, cognitive reserve, global cognitive functioning, and self-reported depressive symptoms was individually presented to 120 community dwellers (Mage = 82 years, SD = 8.4 years) of the Sardinian Blue Zone. Significant associations were found between cognitive reserve, motor efficiency, and self-reported depressive signs. Moreover, three mediation analyses documented that distinct indexes of cognitive reserve and motor efficiency explain 27.2-31% of the variance in the self-reported depression condition. Following this, it was also found that people with scarce cognitive reserve tended to exhibit significant signs of depression and showed worse motor abilities. In addition, after controlling for the effect of global cognitive functioning, motor efficiency, and cognitive reserve were generally more preserved in males than in females. Overall, these findings suggest that cognitive reserve is a compensatory resource that contributes significantly to the enhancement of health-related quality of life in the last decades of life.

Motor and cognitive skills implicated in the Motor Observation Questionnaire for Teachers (MOQ-T): A multidisciplinary approach.

This study was designed to determine the relationship between an observational measure of motor skills for teachers (i.e., MOQ-T), age, and some objectively assessed cognitive and motor indices. Two further goals were to examine which motor and cognitive factors predicted MOQ-T scores and to explore whether pupils with very low motor skills identified through MOQ-T also exhibited lower scores on objectively assessed motor and visuo-spatial tasks. A sample of 156 pupils aged 8.4 years-11.3 years and attending Italian primary school completed a battery of tests assessing writing speed, visuo-spatial abstract reasoning, fluency, and static balance abilities objectively assessed by measuring postural sway. Small to medium associations were found between MOQ-T scores and age, motor, and cognitive parameters, respectively. Moreover, approximately 26% of the variance in MOQ-T was predicted by sway area in the eyes-open condition, visuo-spatial fluency, and writing speed. Finally, pupils at risk of developmental coordination disorder exhibited poorer writing speed, and motor and higher-order visuo-spatial deficits. In conclusion, the synergistic use of objective measures of motor and cognitive functioning and observational screening questionnaires such as MOQ-T should be encouraged at school to identify pupils at risk of developmental coordination disorder.

Smoothness of Gait in Overweight (But Not Obese) Children Aged 6-10.

Excessive body mass represents a serious threat to the optimal psychophysical development of children, and it is known to be able to significantly affect their locomotor capabilities, making them more prone to the development of musculoskeletal disorders. However, despite the relevant number of existing studies, a clear gait pattern of overweight children has not been defined yet, particularly in the case of a mass excess that is relatively small (i.e., in those not obese). In the present study, we employed a wearable inertial measurement unit placed on the low back to derive spatio-temporal parameters and quantify the smoothness of gait (by means of harmonic ratio) from trunk accelerations acquired during gait trials carried out by 108 children aged 6-10 (46% males), stratified into two groups according to their body mass index (normal weight, n = 69 and overweight, n = 39). The results show that while gait speed, stride length, cadence and double support duration were found to be almost identical in the two groups, significant differences were observed in terms of harmonic ratio. In particular, overweight children exhibited a reduced harmonic ratio in the antero-posterior direction and higher harmonic ratio in the medio-lateral direction. While the significantly lower harmonic ratio in the antero-posterior direction is likely to be indicative of a loss of smoothness in the walking direction, probably due to a combination of factors associated with the altered movement biomechanics, the higher harmonic ratio in the medio-lateral direction might be associated with specific strategies adopted to increase lateral stability. Although further studies are necessary to elucidate the specific mechanisms that influence the smoothness of gait, it is noteworthy that harmonic ratios appear sensitive even to subtle change in locomotor control in overweight children characterized by apparently regular spatio-temporal parameters of gait and might be employed to assess the effectiveness of interventions designed to improve mobility functions.

Do cognitive reserve and executive functions matter to perform the reading the mind in the eyes test in late lifespan?

Theory of Mind (ToM) is the capacity to understand the feelings and emotional states (i.e., affective ToM) or intentions, goals, and beliefs (i.e., cognitive ToM) of others. Previous evidence on the effect of executive functions and educational attainment on affective ToM is controversial. This study was conducted to investigate: (1) the nature of the associations between affective ToM and some indexes of cognitive reserve (i.e., years of education, vocabulary) in late adulthood when age was controlled; (2) whether cognitive reserve (e.g., years of education, leisure activities, vocabulary) and age predicted affective ToM in late adulthood; (3) the associations between affective ToM and some executive functions measures in late adulthood, controlling for the effect of age; (4) whether executive functioning predicted affective ToM performance; (5) whether some executive functions (i.e., cognitive flexibility and inhibition) mediated between vocabulary score (i.e., used as an index of cognitive reserve) and affective ToM score. Fifty-six 75-93-year-old community-dwellers completed a battery of tasks to assess some executive functions and affective ToM skills (i.e., through the Reading the Mind in the Eyes Test). It was found that vocabulary, age, and participation in outdoor socio-recreational leisure activities predicted 31% of the variance in the Reading the Mind in the Eyes condition. Moreover, significant relationships were found between ToM and some executive functions, that is, cognitive flexibility and inhibition predicted 34% of the ToM score. Finally, cognitive flexibility and inhibition mediate between cognitive reserve (i.e., assessed in terms of vocabulary) and Reading the Mind in the Eyes test score.

The contribution of motor efficiency to drawing performance of older people with and without signs of cognitive decline.

In clinical practice, different drawing tests are used for the assessment of cognitive efficiency in the geriatric population. However, so far, the contribution of motor skills to drawing performance has not been sufficiently examined in the late adult life span. This study was aimed at disentangling the role played by motor functioning in three well-known drawing tests that in the clinical field are commonly used to detect some signs of cognitive impairment of older individuals. One hundred and forty-nine community dwellers (Mage = 77.4 years, SD = 5.9 years) completed a battery of tests assessing global cognitive efficiency, drawing skills (i.e., Clock Drawing, Visuo-spatial Drawing ACE-R, Copy Figures Tests), handgrip muscular strength (HGS), and functional mobility (assessed through the Timed-Up-and-Go test). Significant relationships were found among those measures. Moreover, handgrip strength and functional mobility explained 12-19% of the variance in each drawing condition. Finally, participants exhibiting poorer HGS performed worse the drawing tasks and were successively recognized as cognitively deteriorated. In conclusion, these findings highlight that motor skills can significantly impact the assessment of cognitive efficiency in late adulthood. Therefore, in clinical practice, the concurrent assessment of basic motor functions (in terms of muscular strength and functional mobility) and cognitive efficiency of the geriatric population at risk for cognitive decline should be encouraged.

The efficiency of activities of daily living (ADLs) skills in late adulthood: A mediational approach.

The term "Activities of Daily Living" (ADLs) refers to a set of fundamental tasks (i.e., toileting, bathing, personal care, eating, grooming, and getting dressed) considered necessary for living and being autonomous in everyday life. Although in the clinical setting ADLs efficiency is a marker to diagnose dementia, limited evidence on the mechanism implicating muscular function and cognitive alterations in ADLs skills in late adulthood exists. This study primarily intended to determine the extent to which executive functions mediate between muscular strength, as assessed through handgrip strength (HGS) measurement, and ADLs skills of older community-dwellers. A further goal was to explore the impact of gender and cognitive status on ADLs and HGS scores, using education as a covariate. Three hundred and thirty-four older participants, 199 females and 135 males (Mage = 77.5 years, SD = 5.6 years, age range = 63-93 years) completed a battery of tests assessing ADLs, HGS, and executive functions. The results showed that 34-56% of the variance in the ADLs condition was explained by HGS and executive functioning. Furthermore, cognitively healthy participants exhibited better ADLs skills, whereas cognitively impaired individuals, both males and females, exhibited poorer HGS efficiency. In conclusion, in clinical settings, the concurrent evaluation of ADLs skills, motor, and higher-order cognitive processes should be encouraged to detect individuals needing a person-tailored intervention to boost their quality of life.

Executive and Motor Functions in Older Individuals with Cognitive Impairment.

BACKGROUND: A current research trend is the examination of the interplay between cognitive functioning, higher-order processes, and motor efficiency in late adulthood. However, the association between motor and cognitive functions when cognitive decline occurs has not been extensively explored. This study investigated whether gait features, functional mobility, and handgrip strength were associated with executive functions in older people with mild cognitive impairment (MCI) or dementia. METHODS: 127 older participants (Mage = 77.9 years, SD = 5.8 years) who had received a diagnosis of MCI and dementia voluntarily took part in the study. A battery of tests assessing global cognitive function, executive functions, muscular strength, functional mobility, and spatio-temporal parameters of gait was completed by the participants. RESULTS: Statistically significant correlations were obtained between global cognitive function, executive functions, and motor efficiency measures. Moreover, a series of regression analyses showed that 8-13% of the variance of several motor parameters was predicted by several executive functions. Additionally, walking, functional mobility, and global cognitive function predicted 53-71% of the variance relative to the occurrence of dementia. In conclusion, motor functioning is closely related to cognitive functioning in late adulthood. CONCLUSIONS: The assessment of muscular strength and functional mobility should be promoted in clinical settings.

Are subjective cognitive complaints associated with executive functions and mental health of older adults?

Subjective cognitive complaints are used to detect detrimental age-related variations in cognitive efficiency before cognitive decline occurs in late adulthood. Despite this, there is controversial evidence on the relationship between the aforementioned metacognitive measure and the actual cognitive efficiency of older individuals. Instead, subjective cognitive complaints seem to be related to perceived mental health. This study aimed to investigate the nature of the relationships between subjective cognitive failures, mental health, and executive functioning. An additional goal was to examine whether there were significant differences in perceived mental health and executive functions efficiency by comparing older people who exhibited fewer subjective cognitive complaints with a group who reported more cognitive complaints. Eighty-nine community-dwellers (Mage = 78.6 years, SD = 6.5 years; age range = 66-95 years), 42 males and 47 females, were recruited and completed a battery of tools assessing cognitive failures, depressive symptoms, psychological well-being, optimism, global cognitive functioning, vocabulary, and several executive functions. Significant relationships were only found between self-reported cognitive failures, depressive symptoms, optimism, and psychological well-being. Moreover, participants who reported more cognitive failures also exhibited less optimism and psychological well-being and showed more depressive symptoms than older respondents who exhibited fewer cognitive complaints. Finally, no differences in the measures of executive functioning were found between groups exhibiting low vs. high levels of subjective cognitive complaints. In conclusion, the concurrent objective assessment of cognitive functioning and self-reported evaluation of cognitive processes and mental health of older people should be encouraged, to detect possible threats to their well-being.

Well-being, food habits, and lifestyle for longevity. Preliminary evidence from the sardinian centenarians and long-lived people of the Blue Zone.

Lifestyle, physical, and mental health impact successful aging. However, at present, extensive literature about the interplay among perceived mental and physical health, lifestyle, and food intake in long-lived people residing in areas of exceptional longevity is lacking. This study was mainly aimed at examining the relationships among self-assessed life satisfaction, physical health, lifestyle, and food intake in the last two decades of life. A further goal was to investigate the impact of age-related factors on the above variables. The recruitment was mainly conducted in the Sardinian Blue Zone, a well-documented area of exceptional longevity in Sardinia, an Italian Island located in the Mediterranean Sea. Twenty-nine octogenarians (Mage = 83.9 years, SD = 2.7) and 28 gender-matched long-lived (Mage = 97.6 years, SD = 7.9) community-dwellers took voluntarily part in the study. Each participant individually completed a battery of tasks assessing their global cognitive efficiency, life satisfaction, lifestyle, food intake, and perceived physical health. The results highlighted that life satisfaction was significantly associated with time spent on outdoor leisure activities (r = .314, p = .026), perceived physical health (r = .459, p = .001), and carbohydrate intake (r = .333, p = .021). Moreover, the octogenarians and long-lived groups reported similar levels of life satisfaction (t(56) = .573, p = .569, Cohen's d = .164). In conclusion, healthy nutrition habits and a physically active lifestyle boosting mental and physical health are crucial for promoting optimal aging.

Is the Sardinian Blue Zone the New Shangri-La for mental health? Evidence on depressive symptoms and its correlates in late adult life span.

BACKGROUND: An area of extraordinary longevity (i.e., Sardinian Blue Zone) characterized by a very high prevalence of long-lived successful agers has been validated in Sardinia, an Italian island located in the Mediterranean Sea. AIMS: This study was primarily aimed at examining whether dietary habits (intake of vegetables and fruit, animal-derived proteins, and carbohydrates-rich food), time spent on hobbies, subjective physical health, and socio-cultural context (Sardinian Blue Zone vs. another Sardinian rural area) predicted self-reported depressive symptoms in older adults recruited in the Sardinian Blue Zone and another Sardinian rural area not being characterized by a higher prevalence of long-lived individuals. METHODS: Three hundred and eighteen community-dwellers, age 65 years and older, 188 females and 130 males (Mage = 79.1 years, SD = 6.9 years) were recruited from the Sardinian Blue Zone and another Sardinian rural area. Each participant individually completed a battery of instruments to assess lifestyle, food habits, perceived physical health, and depressive symptoms through the CES-D inventory. RESULTS: Significant associations were found between depressive signs, perceived physical health, time spent gardening, proteins, and carbohydrates intake, respectively. Approximately 17% of the variance in the CES-D condition was predicted by socio-cultural context, perceived physical health, and gardening. Participants recruited in the Sardinian Blue Zone spent more time gardening and self-reported better physical health. CONCLUSIONS: current results suggest that a socio-cultural context where people age well (i.e., the Sardinian Blue Zone), and a healthy and physically active lifestyle are crucial for promoting well-being in late adulthood.

Associations between migration experience and perceived mental health in optimal ageing: Evidence from the Sardinian Blue Zone.

The effect of migration on perceived mental health has not been examined in older migrants after their return to their places of origin. This study was mainly aimed at evaluating the perceived mental health of older people who experienced migration and permanent resident peers living in the Sardinian Blue Zone (i.e. one of the four areas of exceptional longevity in the world). Forty-eight community-based older participants (32 males and 16 females) with and without a migration experience were recruited in two villages of the Sardinian Blue Zone and completed a battery of self-report inventories assessing psychological well-being, negative mood, and ego resilience. Older individuals who experienced migration reported higher ego resilience and exhibited greater resources used to manage positive emotionality (i.e. openness to life experiences). Moreover, compared to the normative data, both the groups reported higher psychological well-being and fewer depressive symptoms. Finally, no significant associations were found between the length of migration and each mental health index. In conclusion, resilience seems to represent a psychological trait that helps to manage stressful events and contributes to the preservation of perceived mental health in late adulthood.

Motor proficiency as a correlate of coping in late adult lifespan. An exploratory study.

BACKGROUND AND OBJECTIVES: A body of studies suggests that coping resources may represent a protective factor against functional and cognitive losses associated with advanced ageing. This study intended to examine the contributions of global cognition, functional mobility, and muscular strength on self-reported coping strategies in late adulthood. METHODS: One hundred and thirty-seven community-based older individuals (Mage = 77.2 years, SD = 5.8 years, age range: 63-92 years), 48 males and 89 females with and without signs of cognitive decline completed a battery of tools assessing global cognitive function, problem-focused coping, muscular strength (assessed by handgrip strength, HGS) and functional mobility (assessed using the instrumented Timed-Up-and-Go test). RESULTS: Significant associations were found between problem-focused coping, global cognitive function, HGS, functional mobility parameters, age, and education. Moreover, when the effects of education and gender were controlled for, HGS, functional mobility, and global cognitive function scores accounted for 44% of the variance in coping. CONCLUSIONS: In clinical practice, the use of functional mobility and muscular strength measures to screen the physical health of older individuals should be encouraged.

The Impact of SARS-CoV-2 (COVID-19) and its Lockdown Measures on the Mental and Functional Health of Older Individuals.

The effect of the COVID-19 on the physical and mental health of Italian older individuals displaying signs of cognitive deterioration has not been deeply investigated. This longitudinal study examined the impact of COVID-19 lockdown measures on the psychological well-being and motor efficiency of a sample of Italian community-dwellers with and without cognitive decline. Forty-seven participants underwent instrumental gait analysis performed in ecological setting using wearable sensors, and completed a battery of tasks assessing cognitive functioning and psychological well-being, before and after the full lockdown due to the COVID-19 spreading. A series of Multivariate Analyses of Variance (MANOVAs) documented that the superior gait performance of the cognitively healthy participants exhibited before the COVID-19 spread, vanished when they were tested at the end of the lockdown period. Moreover, before the outbreak of the COVID-19, cognitively healthy participants and those with signs of cognitive decline reported similar levels of psychological well-being, whereas, after the lockdown, the former group reported better coping, emotional competencies, and general well-being than the participants displaying signs of cognitive decline. In conclusion, the full COVID-19 outbreak had a significant impact on the mental and motor functioning of older individuals with and without signs of cognitive deterioration living in Italy.

Mental Health and Religiosity in the Sardinian Blue Zone: Life Satisfaction and Optimism for Aging Well.

This study evaluated the impact of the sociocultural context on dispositional optimism and resilience, life satisfaction, and religiosity in late adulthood. Moreover, the associations between those psychological measures and religiosity were investigated. Ninety-five older individuals recruited in the Sardinian Blue Zone and Cagliari completed a battery of tools assessing cognitive and mental health, and religiosity. Life satisfaction correlated with resilience and religiosity, whereas resilience correlated with optimism. Furthermore, participants of the rural area reported greater optimism and life satisfaction than peers living in the urban area. In conclusion, optimism and hedonic well-being favor optimal aging in the Blue Zone.

Mental health and motor efficiency of older adults living in the Sardinia's Blue Zone: a follow-up study.

OBJECTIVES: The main aim of this study was to examine the impact of age-related changes on mental health, metacognitive, and motor functioning in late adulthood, while controlling for the effect of gender. Additionally, this investigation intended to study the association between motor efficiency indexes and self-reported psychological well-being, depression and cognitive failures over a period of 24 months. DESIGN: Prospective longitudinal study: post hoc analysis. PARTICIPANTS: Ninety-one community-dwelling older participants (mean age = 78.7 years, SD = 5.6) were recruited in a rural village of the Sardinian Blue Zone - an area of exceptional longevity located in the central-eastern region of Sardinia, an Italian island in the Mediterranean Sea. MEASUREMENTS: All respondents completed a battery of tests and questionnaires assessing motor and general cognitive efficiency, self-reported psychological well-being, negative affect, and cognitive failures. RESULTS: The adoption of a multilevel modeling approach highlighted the significative impact of time on psychological well-being, as well as on mobility parameters like gait speed and cadence, while controlling for the gender effect. Overall, psychological well-being and motor swing significantly increase at follow-up, whereas the further above-mentioned measures decreased after 24 months. Moreover, compared to the national cut-off, at baseline and follow-up, participants reported higher perceived emotional well-being. Finally, significant relationships between motor scores and self-reported mental health and metacognitive measures were found both at baseline and follow-up. CONCLUSIONS: The maintenance of motor efficiency and preserved mental health seems to contribute to the successful aging of older people living in the Sardinian Blue Zone.

Life satisfaction in late adult span: the contribution of family relationships, health self-perception and physical activity.

BACKGROUND: Life satisfaction is a crucial facet of subjective well-being, being impacted by different factors, such as cognitive and physical health, and social functioning. AIMS: This study intended to investigate the impact of satisfaction with family ties, education, negative mood and health self-perception on life satisfaction in late adulthood. METHODS: One hundred fifteen cognitively intact 75-101-year-old participants competed a battery of tools assessing cognitive efficiency and self-referent measures of life satisfaction, perceived physical health, negative mood and satisfaction with family relations. RESULTS: A series of step-wise regression analyses showed that satisfaction with family ties with and without perceived physical health predicted different indexes of life satisfaction. Moreover, more physically active participants reported fewer depressive symptoms and better life satisfaction with their time occupied in leisure activities than more sedentary respondents. CONCLUSION: Perceived emotional connection with family members and a physically active lifestyle represent the most significant protective factors to boost self-reported life satisfaction in late adulthood.

The role of cognitive reserve as mediator for addition and multiplication skills in late adulthood.

BACKGROUND: The role played by cognitive reserve for the maintenance of numeracy skills in late adulthood is still not sufficiently explored. AIMS: This study mainly investigated whether cognitive reserve (i.e., vocabulary) mediates on the relationship between non-verbal reasoning and addition and multiplication skills of older individuals. Moreover, the impact of schooling and gender on written calculation was examined, controlling for the effect of cognitive decline. METHODS: One hundred and six 68-94-year-old participants completed a battery of tests assessing numeracy, executive functions, and cognitive reserve skills. RESULTS: Significant correlations were found between age, cognitive reserve, numeracy, and executive functions measures. Besides, mediation analyses indicated that cognitive reserve and non-verbal reasoning explain 23% and 29% of the variance in written addition and multiplication conditions, respectively. Finally, more educated individuals performed better numeracy tasks, whereas the solution of additions and multiplications was not impact by gender. CONCLUSIONS: Cognitive reserve impacts numeracy in late adulthood.
