Association of objective sedentary behaviour and self-rated health in English older adults

Associations of Physical Activity and Sedentary Behavior With Self-Rated Health Status in Brazilian Older Adults

In a longevity society, as we live longer, adopting healthy lifestyles is essential to develop and maintain functional ability, which enables well-being in older adults. We aim to examine the associations of physical activity (PA) and sedentary behaviors (SBs) with self-rated health (SRH) status in older Brazilian adults. We analyzed 21,701 persons aged 60 or older from the Brazilian National Health Survey. A partial proportional odds model for SRH adjusted by sociodemographic confounders was estimated. The marginal effects of PA and SB on SRH status were expressed in terms of the average-adjusted probabilities. In addition, average-adjusted probabilities for the better and worse SRH status among representative cases of Brazilian socioeconomic inequalities were calculated. The main findings of the study indicate: (a) a significant positive association exists between PA and SRH status and, conversely, a negative association exists between SB and SRH; (b) the PA effect across daily sitting time watching TV attenuated and improved the probability of declaring a worse and better SRH status, respectively; and (c) the SRH status differences associated with PA and SB represent the socioeconomic inequalities in the older Brazilian population. Beyond some methodological limitations, we conclude that increasing PA and SB in older persons is significantly associated with better and worse SRH status, respectively. In addition, the results suggest that SRH status is a consistent health inequality measurement. In societies moving on longevity transition, substantial efforts are required in individuals' behavior across the life courses and public policies to promote healthy aging.

Associations of 24-hour movement guidelines adherence with fruit and vegetable intake in university students

Background

Unhealthy eating habits, such as low vegetable and fruit intake, are associated with many health problems. 24-h movement behaviors have been reported to be positively associated with numerous health-related outcomes. Despite the importance of these two modifiable lifestyle behaviors in building healthy habits in university students, there is a paucity of relevant research in this population. Therefore, this study aims to examine the correlation between compliance with 24-h movement guideline (24-h MG) and intake of fruits and vegetables (IFV) in Chinese university students.

Methods

This study investigated the relationship between the compliance with 24-h MG and IFV in 1,793 Chinese university students using a convenience sampling method online. Physical activity (PA) and sedentary behavior (SB) were assessed by the International Physical Activity Questionnaire-Short Form, while sleep was measured using the Pittsburgh Sleep Quality Index. The Chinese version of the Health Promoting Lifestyle Profile II was used to measure IFV. Generalized linear models were applied to examine the correlation between compliance with the 24-h MG and eating habits.

Results

The proportion of participants who routinely consumed vegetables and fruits was 24.6% and 43.1%, respectively, while the proportion of meeting the three 24-h MG and a combination of any two guidelines was 27.8% and 40.1%, respectively. Meeting all three guidelines was associated with a greater IFV intake compared to not meeting either guideline. Meeting all three guidelines (OR = 2.42 [1.63, 3.58]) and the combination of moderate to vigorous PA (MVPA) and sleep (OR = 2.06 [1.37, 3.10]) were positively associated with the frequency of vegetable consumption (p < 0.05). As well, meeting all three guidelines (OR = 2.06 [1.37, 3.10]), the combination of MVPA and sleep (OR = 1.72 [1.04, 2.84]), and sleep only (OR = 1.88 [1.21, 2.92]) were positively associated with fruits consumption (p < 0.05).

Conclusion

Almost a third of the university students met the three 24-h MG, and compliance with all three guidelines was associated with a higher frequency of IFV. Furthermore, meeting the sleep guideline alone or in conjunction with the PA, and meeting the entire 24-h MG was associated with greater consumption of fruits.

Daily activity patterns in older adults receiving initial support: the association between daily steps and sitting in bouts of at least 60 min

BACKGROUND

Aging has a significant impact on health, underlining the importance of maintaining physical function and reducing time spent sitting among older adults. To understand how to reduce prolonged sitting or increase physical activity, factors related to the daily living and observed daily activity patterns should be explored. This study aimed to investigate the association between daily steps, self-rated health, physical activity, sedentary behavior, motivation to exercise and fear of falling among older adults receiving initial support.

METHOD

Cross-sectional design with total population questionnaire data from adults aged ≥ 60 years (n = 917), living at home with initial support from municipal care in southern Sweden. The older adults were offered to participate in a follow-up study measuring daily activity patterns with accelerometers (n = 72). Linear regression was used to analyze associations between daily steps and possible predictors.

RESULTS

The linear model ([Formula: see text]0.478) showed that sitting in unbroken bouts of > 60 min (β = -0.313, p < 0.05), walking independently outdoors (β = 0.301, p < 0.05), intending to increase physical activity (β = -0.294, p < 0.05), sex (β = 0.279, p < 0.05), relative autonomy index (β = 0.258, p < 0.05), fear of falling (β = -0.238, p < 0.05), and self-rated health (β = 0.213, p < 0.05) predicted daily steps.

CONCLUSION

The model of predictors brings new understanding regarding daily steps among community-dwelling older adults. The association between sitting in bouts of > 60 min and daily steps is interesting as 35% of participants had a number of sitting bouts that on average, showed 30% less steps taken. Minimizing long sitting bouts and maintaining physical functioning to promote independence when walking outdoors can be tools for clinical practitioners devising interventions to break prolonged sitting among community-dwelling older adults. Future research should prioritize studying older adults' outdoor walking independence, including its relation to walking with or without assistive devices and its impact on physical activity and sedentary behavior.

Subjective socioeconomic status and self-rated health in the English Longitudinal Study of Aging: A fixed-effects analysis

Higher subjective socio-economic status (SES) goes along with better self-rated health: This finding is well-established in the literature, yet the majority of studies it is based on only rely on cross-sectional analyses and only account for few potential confounders of the association. Particularly wealth, which is increasingly thought of as an important dimension of accumulated advantage, is only rarely examined as a confounder. Using eight waves of panel data from the English Longitudinal Study of Aging (ELSA, 2002-19), we investigate the association between subjective SES and self-rated health. We use random effects models that account for theoretically important time-constant (such as education and social class) and time-varying confounders (such as income and wealth) as well as fixed-effects models, that in addition control for all time-constant confounders, whether observed or unobserved. The fully adjusted fixed-effects model reveals a statistically significant association between subjective SES and self-rated health. Yet, a one-point increase on the subjective SES ladder goes along with a two per cent of a standard deviation increase in self-rated health, only around a quarter of the size of the random-effects estimate. The role of wealth for the subjective SES-self-rated health association is negligible in the fixed-effects specifications. Smoking, drinking, and physical activity do not appear to mediate the association. A substantial part, though not all, of the observed association between subjective SES and self-rated health is due to unobserved confounding rather than a causal effect. Reducing health inequalities based on objective SES is likely more effective than based on subjective SES.

Does the built environment influence location- and trip-based sedentary behaviors? Evidence from a GPS-based activity space approach of neighborhood effects on older adults

OBJECTIVE

Evidence on the influence of built environments on sedentary behaviors remains unclear and is often contradictory. The main limitations encompass the use of self-reported proxies of sedentary time (ST), the scarce consideration of the plurality of sedentary behaviors, and environmental exposures limited to the residential neighborhood. We investigated the relationships between GPS-based activity space measures of environmental exposures and accelerometer-based ST measured in total, at the place of residence, at all locations, and during trips.

METHODS

This study is part of the CURHA project, based on 471 older adults residing in Luxembourg, who wore a GPS receiver and a tri-axial accelerometer during 7 days. Daily ST was computed in total, at the residence, at all locations and during trips. Environmental exposures included exposure to green spaces, walking, biking, and motorized transportation infrastructures. Associations between environments and ST were examined using linear and negative binomial mixed models, adjusted for demographics, self-rated health, residential self-selection, weather conditions and wear time.

RESULTS

Participants accumulated, on average, 8 h and 14 min of ST per day excluding sleep time. ST spent at locations accounted for 83 % of the total ST. ST spent at the residence accounted for 87 % of the location-based ST and 71 % of the total ST. Trip-based ST represents 13 % of total ST, and 4 % remained unclassified. Higher street connectivity was negatively associated with total ST, while the density of parking areas correlated positively with total and location-based ST. Stronger associations were observed for sedentary bouts (uninterrupted ST over 20 and 30 min).

CONCLUSION

Improving street connectivity and controlling the construction of new parking, while avoiding the spatial segregation of populations with limited access to public transport, may contribute to limit ST. Such urban planning interventions may be especially efficient in limiting the harmful uninterrupted bouts of ST among older adults.

Associated factors of doctor visits made by urban-dwelling older adults in Sri Lanka: an application of Anderson's model of health service utilization

Background

Although universal free healthcare is available for all Sri Lankan citizens, older adults face somewhat unique obstacles when utilizing available healthcare services. The aim of this study was to examine some vital predisposing, enabling, and need factors associated with doctor visits made by urban-dwelling older adults in Sri Lanka.

Methods

A representative sample of 880 urban-dwelling older adults (aged 60 years and above) was surveyed using an interviewer-administered questionnaire. Number of doctor visits, self-rated health, physical activity, and socio-demographic and self-report health conditions were collected. The data were analyzed using chi-squared tests and multinomial logistic regression.

Results

Participants’ mean age was 70.01 (± 6.02) years. The majority was women (75.0%). The mean number of doctor visits was 6.77 (± 5.92) per year. Nearly half of the participants (47.0%) had made, on average, at least one doctor visit per month. Older men and those of aged 80 years and above were the least likely to make frequent doctor visits. Participants who were physically active and who rated their health as poor were more likely to make frequent doctor visits after adjustment for age, gender, and educational level.

Conclusions

Doctor visits made by Sri Lankan older adults are satisfactory. The factors that best explain high frequency of doctor visits by older adults are female gender, younger age, higher physical activity and poor self-rated health. Attention should be paid to examine possible accessible and affordable issues related to doctor visits by bedridden or physically dependent older adults in advanced age categories.

Pathways to healthy aging - Exploring the determinants of self-rated health in older adults

OBJECTIVE

The decade 2021-2030 has been declared the Decade of Healthy Aging by the United Nations General Assembly, underlining that health is central to the experience of older age and the opportunities that aging brings. Self-rated health (SRH) appears consistent with the state of objective health, and therefore can serve as a simple core indicator of healthy aging. SRH can be affected by psychological and lifestyle factors, and by the developmental and sociodemographic context, which can directly and indirectly influence subjective health status. The aim of the present study was to establish the structure of the relationships between SRH, health-related behavior, subjective wellbeing, developmental tasks attainment and sociodemographic factors in the late-life period.

METHODS

The study group consisted of 340 Polish retired seniors, aged 61 to 94 (M = 70.75, SD = 6.48): 88 men (25.9 %) and 252 women (74.1 %). The respondents completed the following measures: 10-point numerical scale for SRH, Health-Related Questionnaire for Seniors, Satisfaction with Life Scale, Developmental Tasks Questionnaire for Seniors and a sociodemographic survey.

RESULTS

The group demonstrated a medium level of SRH and other variables. SHR was positively correlated with health-related behavior, wellbeing, developmental tasks attainment and perceived economic status, and negatively with age. Structural equation model revealed that health-related behavior, wellbeing, age and economic status have a direct influence on SRH. Developmental tasks attainment was found to predict health behavior, although no direct relationship with SRH was found.

CONCLUSIONS

A broader understanding of healthy aging is achieved by considering the context of its factors. Psychological interventions should promote a healthy lifestyle and adapt it to the late life period to promote health among seniors.

A Cross-Sectional Study of the Relationship Between Exercise, Physical Activity, and Health-Related Quality of Life Among Japanese Workers

Background

Studies have determined that exercise and physical activity positively affect physical and mental health, and that healthy workers contribute to increased work performance. The relationship between the time spent on exercise during leisure time and physical activity, including work, with health-related quality of life (HRQOL) in workers is unclear, with variations observed between occupational types. This cross-sectional study examined these associations among Japanese workers from various occupations during the COVID-19 pandemic.

Methods

An Internet-based national health survey-Collaborative Online Research on Novel-coronavirus and Work-study (CORoNaWork study)-was conducted among 33,087 Japanese workers in December 2020. After excluding invalid responses, 27,036 participants were categorized into four and five groups according to exercise and physical activity time, respectively. Each group's scores were compared on each of the four questions on the Japanese version of the Centers for Disease Control and Prevention Health-Related Quality of Life (CDC HRQOL-4) using generalized linear models. Age-sex adjusted and multivariate models were used to compare each index of the CDC HRQOL-4.

Results

Compared to the reference category (almost never), any level of exercise (ORs 0.56-0.77) and physical activity (ORs 0.93-0.88) were associated with better self-rated health in the multivariate model. Any exercise was also associated with significantly reduced odds for physically or mentally unhealthy days; however, high levels of physical activity (≥120 min/day) were associated with significantly increased odds for these outcomes (ORs = 1.11 and 1.16, respectively).

Conclusions

The results suggest that exercise habits are more critical to workers' HRQOL than physical activity. Interventions that encourage daily exercise even for a short time are likely to be associated with better workers' health and work performance.

Association of Self-Reported and Device-Measured Sedentary Behaviour and Physical Activity with Health-Related Quality of Life among European Older Adults

Human movement behaviours such as physical activity (PA) and sedentary behaviour (SB) during waking time have a significant impact on health-related quality of life (HRQoL) in older adults. In this study, we aimed to analyse the association between self-reported and device-measured SB and PA with HRQoL in a cohort of community-dwelling older adults from four European countries. A subsample of 1193 participants from the SITLESS trial (61% women and 75.1 ± 6.2 years old) were included in the analysis. The association between self-reported and objective measures of SB and PA with HRQoL were quantified using Spearman’s Rho coefficients. The strength of the associations between self-reported and device-measured PA and SB with self-rated HRQoL (mental composite score, MCS; physical composite score, PCS) were assessed through multivariate multiple regression analysis. Self-reported and device-measured PA and SB levels showed significant but poor associations with PCS (p < 0.05). The association with MCS was only significant but poor with self-reported light PA (LPA) and moderate-to-vigorous PA (MVPA). In conclusion, the findings of this study suggest that both self-reported and device-measured PA of all intensities were positively and significantly associated, while SB was negatively and significantly associated with the PCS of the SF-12.

The Impact of Sedentary Behavior and Self-Rated Health on Cardiovascular Disease and Cancer among South Korean Elderly Persons Using the Korea National Health and Nutrition Examination Survey (KNHANES) 2014-2018 Data

Cardiovascular disease and cancer have increased the risk of mortality and morbidity in elderly persons worldwide. The aim of this study was to investigate the association of sedentary behavior and self-rated health with cardiovascular disease or cancer in elderly people. The data of 6785 elderly persons aged above 65 years from the Korea National Health and Nutrition Examination Survey 2014-2018 were examined. Binary logistic regression analyses assessed the association of sedentary behavior, self-rated health, and other risk factors with cardiovascular disease or cancer. Prolonged sedentary behavior in elderly people was associated with a high risk for cardiovascular disease (odds ratio (OR): 1.28, 95% confidence interval (CI): 1.08-1.52). There was a high risk for cardiovascular disease (OR: 2.36, 95% CI: 1.85-3.01) or cancer (OR: 1.48, 95% CI: 1.17-1.88) in elderly people who had poor self-rated health. This study identified the association between prolonged sedentary behavior and cardiovascular disease, and between poor self-rated health and cancer. Since prolonged sedentary behavior is related to cardiovascular disease, efforts are needed to reduce sedentary behavior hours and maintain good self-rated health.

Associations of meeting 24-h movement guidelines with stress and self-rated health among adults: is meeting more guidelines associated with greater benefits?

Background

Several countries have recently issued 24-h movement guidelines that include quantitative recommendations for moderate-to-vigorous physical activity (MVPA), sedentary behaviour (SB), and sleep. This study explored the associations of meeting the 24-h movement guidelines with stress and self-rated health among adults, and whether the likelihood of favourable outcomes increases with the number of guidelines met.

Methods

A total of 2476 adults aged 18 years and over completed a questionnaire on their time spent in MVPA, SB and sleep, frequency of stress (never, very rarely, occasionally, often, every day), self-rated health (very good, good, fair, bad, very bad), sociodemographic characteristics, and lifestyle variables.

Results

In an ordinal logistic regression analysis adjusted for age, sex, body mass index, education, socio-economic status, employment, place of residence, living with or without partner, and smoking, lower odds of higher frequency of stress were found for those meeting the combined 24-h movement guidelines (adjusted odds ratio [OR] = 0.45; 95% confidence interval [CI]: 0.32, 0.63; p <  0.001), any combination of two guidelines (OR range: 0.48–0.63; p <  0.05 for all), and sleep guideline only (OR = 0.51; 95% CI: 0.35, 0.75; p = 0.001). Higher odds of better self-rated health were found for those meeting the combined 24-h movement guidelines (OR = 2.94; 95% CI: 2.07, 4.19; p <  0.001), combination of MVPA and SB guidelines (OR = 2.33; 95% CI: 1.57, 3.44; p <  0.001), combination of MVPA and sleep guidelines (OR = 1.78; 95% CI: 1.23, 2.59; p = 0.002), and MVPA guideline only (OR = 2.24; 95% CI: 1.50, 3.36; p <  0.001). Meeting more guidelines was associated with greater odds of favourable outcomes (p for linear trend < 0.001).

Conclusion

Adults who meet the sleep guideline, any combination of two guidelines, or all three guidelines experience stress less frequently. Meeting the MVPA guideline alone or in combination with any other movement behaviour guideline was associated with better self-rated health. The likelihood of less frequent stress and better self-rated health increases with the number of guidelines met. Adults should be encouraged to meet as many movement behaviour guidelines as possible.

Accelerometer-Measured Sedentary and Physical Activity Time and Their Correlates in European Older Adults: The SITLESS Study

Background

Sedentary behavior (SB) and physical activity (PA) are important determinants of health in older adults. This study aimed to describe the composition of accelerometer-measured SB and PA in older adults, to explore self-reported context-specific SB, and to assess sociodemographic and functional correlates of engaging in higher levels of SB in participants of a multicenter study including four European countries.

Method

One thousand three hundred and sixty community-dwelling older adults from the SITLESS study (61.8% women; 75.3 ± 6.3 years) completed a self-reported SB questionnaire and wore an ActiGraph accelerometer for 7 days. Accelerometer-determined compositional descriptive statistics were calculated. A fixed-effects regression analysis was conducted to assess the sociodemographic (country, age, sex, civil status, education, and medications) and functional (body mass index and gait speed) correlates.

Results

Older adults spent 78.8% of waking time in SB, 18.6% in light-intensity PA, and 2.6% in moderate-to-vigorous PA. Accelerometry showed that women engaged in more light-intensity PA and walking and men engaged in higher amounts of moderate-to-vigorous PA. Watching television and reading accounted for 47.2% of waking time. Older age, being a man, single, taking more medications, being obese and overweight, and having a slower gait speed were statistically significant correlates of more sedentary time.

Conclusions

The high amount of SB of our participants justifies the need to develop and evaluate interventions to reduce sitting time. A clinically relevant change in gait speed can decrease almost 0.45 percentage points of sedentary time. The distribution of context-specific sedentary activities by country and sex showed minor differences, albeit worth noting.

The Effects of Displacing Sedentary Behavior With Two Distinct Patterns of Light Activity on Health Outcomes in Older Adults (Implications for COVID-19 Quarantine)

Rationale: The COVID-19 pandemic is limiting outdoor and community-based activities, especially for older adults owing to the requirement for self-isolation, potentially increasing prolonged sedentary behavior (SB). Given a poor tolerance for intense exercise, SB displacement with light intensity physical activity (LIPA) is a promising health enhancing alternative. Therefore, the aims of this study were to investigate the effects of two different types of SB displacement on health outcomes in older adults and any differential impact of associated LIPA pattern.

Method: 28 older women (age: 73 ± 5 years, height: 1.60 ± 0.07 m, weight: 67 ± 10 kg, and BMI: 26.1 ± 3.6 kg/m²) underwent overnight fasted dual energy x-ray absorptiometry (DEXA) imaging, blood sampling, and functional assessments before being randomly allocated to one of two groups: (1) single continuous bout of 45–50 min LIPA daily (n = 14); or (2) SB fragmentation (SBF; ~48 min LIPA daily, 2 min LIPA for every 30 min of SB; n = 14). Compliance was systematically monitored using tri-axial accelerometery. All measures were taken at weeks 0 and 8.

Results: Physical behavior significantly altered (decreased SB/increased LIPA; p < 0.05) and to a similar extent in both groups. We observed a significant reduction in serum triglycerides [p = 0.045, effect size (ɳ_p²) = 0.15; SBF: −0.26 ± 0.77 mmol/L, LIPA: −0.26 ± 0.51 mmol/L], improved 30 s sit-to-stand (STS) count (p = 0.002, ɳ_p² = 0.32, 2 ± 3 STS) and speed (p = 0.009, ɳ_p² = 0.35, −10 ± 33%), as well as increased average handgrip strength (p = 0.001, ɳ_p² = 0.45, 6 ± 12%), and gait speed (p = 0.005, ɳ_p² = 0.27, 0.09 ± 0.16 m/s) in both groups. Interestingly, SBF caused a greater increase in peak handgrip strength (8 ± 14%), compared to LIPA (2 ± 10%; p = 0.04, ɳ_p² = 0.38).

Conclusion: SB displacement induced significant improvements in fasting triglycerides, gait speed, as-well as STS endurance/speed in older women. Frequent vs. continuous SB displacement also caused greater increases in handgrip strength. While both SB displacement protocols display promise as efficacious home-based interventions for self-isolating older adults, our results would suggest a physical functioning advantage of the SBF protocol for certain outcomes.

A theory-based multicomponent intervention to reduce occupational sedentary behaviour in professional male workers: protocol for a cluster randomised crossover pilot feasibility study

BACKGROUND

Prolonged sitting, a significant risk factor for increased morbidity and mortality, is accumulated mostly in the workplace. There is limited research targeting specific at-risk populations to reduce occupational sedentary behaviour. A recent study found that professional males have the longest workplace sitting times. Current evidence supports the use of multi-level interventions developed using participative approaches. This study's primary aims are to test the viability of a future definitive intervention trial using a randomised pilot study, with secondary aims to explore the acceptability and feasibility of a multicomponent intervention to reduce workplace sitting.

METHODS

Two professional companies in Dublin, Ireland, will take part in a cluster randomised crossover pilot study. Office-based males will be recruited and randomised to the control or the intervention arms. The components of the intervention target multiple levels of influence including individual determinants (via mHealth technology to support behaviour change techniques), the physical work environment (via provision of an under-desk pedal machine), and the organisational structures and culture (via management consultation and recruitment to the study). The outcomes measured are recruitment and retention, minutes spent sedentary, and physical activity behaviours, work engagement, and acceptability and feasibility of the workplace intervention.

DISCUSSION

This study will establish the acceptability and feasibility of a workplace intervention which aims to reduce workplace SB and increase PA. It will identify key methodological and implementation issues that need to be addressed prior to assessing the effectiveness of this intervention in a definitive cluster randomised controlled trial.

Cardiovascular and Quality of Life Outcomes of a 3-Month Physical Exercise Program in Two Brazilian Communities

Background: A reduction in physical activity levels in older people is associated with declining quality of life and lower cardiorespiratory fitness levels associated with cardiovascular disease outcomes and mortality from all causes. Evidence supports the positive effect of community-based exercise (CEXE) programs on cardiovascular health and quality of life. This research aimed to examine the effects of a 3-month CEXE on health-related quality of life and cardiovascular risk factors in two Brazilian populations. Methods: Adults with an average age of 70.2 ± 5.4 years were recruited to engage in an individually designed group based CEXE program two to three times/week (aerobic exercise, circuit resistance training, and stretching exercises for 1 h each time). Once a week, competitions were held to improve socialization and collaboration capacity among group members. The CEXE group was compared with a sedentary group. Cardiovascular outcomes were blood pressure, triglycerides, body mass index, waist circumference, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, total cholesterol, and glycemia. Health-related quality of life was evaluated using the Short Form-36. Results: Of the cardiovascular outcomes studied, the CEXE program significantly reduced systolic blood pressure [5.7 (95% CI 0.2 to 11.3), p < 0.05] and the triglyceride-HDL-C ratio [0.8 (95% CI 0.05 to 1.5), p < 0.05], whereas HDL-C was significantly increased [4.4 (95% CI 0.02 to 8.8), p < 0.05]. A significant improvement in the Short Form-36 subscales occurred in CEXE but not in the control group: physical functioning score [increase of 24.2 (95% CI 11.8 to 36.5) vs. -9.2 (95% CI -21.5 to 3.2), p < 0.001], physical role functioning score [increase of 35.4 (95% CI 12.8 to 58.0) vs. 16.7 (95% CI -6.0 to 39.3), p < 0.01], and general health score [increase of 23.7 (95% CI: 36.9. to 10.4) vs. 2.4 (95% CI -10.9 to 15.7), p < 0.001]. Conclusion: This study shows that in older adults, a 12-week physical activity program can significantly decrease cardiovascular risk and improve health-related quality of life measures. An important transferable sociocultural strategy of our exercise program was to establish social interactions during and outside the CEXE program.

Healthy aging and the University of the Third Age - Health behavior and subjective health outcomes in older adults

INTRODUCTION

By participating in the University of the Third Age (U3A), retirees are offered the opportunity for activation and development in the later years of life. However, little is known how certain aspects of healthy aging, such as health-related behavior and subjective health outcomes, differ between U3A students and other older adults not taking part in any form of education. To address this, the aim of the present study was to compare selected aspects of healthy aging in a group of U3A members with older adults not taking part in any form of lifelong learning. The study also establishes relationships between the tested variables and predictors of health behavior.

MATERIALS AND METHODS

277 older adults (130 U3A members and 147 non-members) aged 60-92 (M = 68.84, SD = 5.32) completed measures of health behavior, self-rated physical health, self-rated sense of own health responsibility and satisfaction with life.

RESULTS

The U3A attendees presented significantly higher scores for general health behavior and some of its components, and declared higher self-rated health than their peers not affiliated to any educational organization. Self-rated health, responsibility for health and satisfaction with life were positively correlated with general health behavior and most of their categories. but the correlation coefficients differed between both groups. A hierarchical regression model demonstrated the predictive roles of attendance in U3A, sociodemographic and subjective factors in health behavior undertaking.

CONCLUSIONS

The study results may help to identify older adults who should be targeted in interventions aimed at supporting healthy aging.

Self-rated health and socio-economic status among older adults in Northern Iceland

Little is known about self-rated health (SRH) of older people living in more remote and Arctic areas. Iceland is a high-income country with one of the lowest rates of income inequality in the world, which may influence SRH. The research aim was to study factors affecting SRH, in such a population living in Northern Iceland. Stratified random sample according to the place of residency, age and gender was used and data collected via face-to-face interviews. Inclusion criteria included community-dwelling adults ≥65 years of age. Response rate was 57.9% (N = 175), average age 74.2 (sd 6.3) years, range 65–92 years and 57% were men. The average number of diagnosed diseases was 1.5 (sd 1.3) and prescribed medications 3.0 (sd 1.7). SRH ranged from 5 (excellent) to 1 (bad), with an average of 3.26 (sd 1.0) and no difference between the place of residency. Lower SRH was independently explained by depressed mood (OR = 0.88, 95% CI = 0.80–0.96), higher body mass index (OR = 0.93, 95% CI = 0.87–0.99), number of prescribed medications (OR = 0.88, 95% CI = 0.78–1.00) and perception of inadequate income (OR = 0.45, 95% CI = 0.21–0.98). The results highlight the importance of physical and mental health promotion for general health and for ageing in place and significance of economic factors as predictors of SRH.

Effects of Physical Exercises and Verbal Stimulation on the Functional Efficiency and Use of Free Time in an Older Population under Institutional Care: A Randomized Controlled Trial

Older people in institutional care are, for the most part, physically inactive and do not interact with each other or medical staff. Therefore, reducing sedentary behaviour is a new, important, and modifiable lifestyle variable that can improve the health of elderly people. The aim of the project was to assess the degree of improvement in functional performance and the possibility of changing habitual, free time behaviour among elderly people under institutional care by applying physical training with verbal stimulation. The study covered older people, aged 65–85 years, who are living a sedentary lifestyle in care homes in Southeastern Poland. Those who met the eligibility criteria were enrolled in the study and were assigned, at random, to one of four parallel groups: basic exercises (n = 51), basic exercises combined with verbal stimulation (n = 51), functional exercise training (n = 51), and functional exercise training with verbal stimulation (n = 51). No statistically significant differences in baseline characteristics were observed across the groups. Data were collected at baseline and at 12 and 24-weeks following the completion of the intervention. In the group with functional exercise training with verbal stimulation, in comparison to the group with basic exercises, the greatest positive short-term impact of intervention was demonstrated in terms of functional fitness (increased by 1.31 points; 95% confidence interval (CI) = 0.93–1.70), gait speed (improved by 0.17 m/s, 95% CI = 0.13–0.22), hand grip strength (by over 4 kg; 95% CI = 2.51–4.95), and upper-limb flexibility (by 10 cm; 95% CI = 5.82–12.65). There was also a significant increase in the level of free-time physical activity and an improvement in the quality of life, especially as expressed in the domain of overall physical functioning. Our study showed that a functional exercise program, combined with verbal stimulation, is effective at improving physical fitness and raising the level of free-time physical activity.

Twenty four-hour activity cycle in older adults using wrist-worn accelerometers: The seniors-ENRICA-2 study

OBJECTIVES

This study aimed: (a) to provide a detailed description of sleep, sedentary behavior (SED), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) over the complete 24-hours period using raw acceleration data in older adults; and (b) to examine the differences in the 24-hours activity cycle by sex, age, education, and body mass index (BMI).

METHODS

Population-based cohort comprising 3273 community-dwelling individuals (1739 women), aged 71.8 ± 4.5 years, participating in the Seniors-ENRICA-2 study. Participants wore a wrist-worn ActiGraph GT9X accelerometer for 7 consecutive days, and the raw signal was processed using the R-package GGIR.

RESULTS

Participants reached 21.5 mg as mean acceleration over the whole day; 32.3% (7.7 h/d) of time was classified as sleep, 53.2% (12.7 h/d) as SED, 10.4% (148.6 min/d) as LPA, and 4.1% (59.0 min/d) as MVPA. No marked differences were found in sleep-related variables between socio-demographic and BMI groups. However, women showed higher LPA but lower SED and MVPA than men. Moreover, SED increased whereas LPA and MVPA decreased with age. Participants with obesity (BMI ≥ 30 kg/m² ) accumulated more SED and less LPA and MVPA than those without obesity. As expected, adherence to physical activity recommendations varied widely (9.2%-76.6%) depending on the criterion of MVPA accumulation.

CONCLUSION

Objective assessment of the 24-hour activity cycle provides extensive characterization of daily activities distribution in older adults and may inform health-promotion interventions in this population. Women, the oldest old, and those with obesity offer relevant targets of strategies to improve lifestyle patterns.
