Prospective relationship between objectively measured light physical activity and depressive symptoms in later life

Community Exercise Program Participation and Mental Well-Being in the U.S. Texas-Mexico Border Region

Hispanics are disproportionately affected by low rates of physical activity and high rates of chronic diseases. Hispanics generally and Mexican Americans specifically are underrepresented in research on physical activity and its impact on mental well-being. Some community-based interventions have been effective in increasing physical activity among Hispanics. This study examined data from a sample of low-income Hispanic participants in free community exercise classes to characterize the association between self-reported frequency of exercise class attendance, intensity of physical activity, and participant well-being. As part of two cross-sectional samples recruited from a stratified random sample of community exercise classes, 302 participants completed a questionnaire consisting of a modified version of the Godin-Shephard Leisure-Time Exercise Questionnaire (LTEQ) and the Mental Health Continuum Short Form (MHC-SF). Adjusted logistic regression analyses indicated that those who achieve mild, moderate, and strenuous self-reported physical activity have 130% higher odds (p = 0.0422) of positive mental well-being after adjustment for age, frequency of attendance, and self-reported health. This study provides evidence that the intensity of physical activity is associated with flourishing mental well-being among Hispanic adults. The association between physical activity and mental well-being is more pronounced when considering participants engaged in mild levels of physical activity. The study further provides insight into the planning and development of community-based physical activity programming tailored to low-income populations.

Developing a Multimodal Monitoring System for Geriatric Depression: A Feasibility Study

The Internet of Medical Things is promising for monitoring depression symptoms. Therefore, it is necessary to develop multimodal monitoring systems tailored for elderly individuals with high feasibility and usability for further research and practice. This study comprised two phases: (1) methodological development of the system; and (2) system validation to evaluate its feasibility. We developed a system that includes a smartphone for facial and verbal expressions, a smartwatch for activity and heart rate monitoring, and an ecological momentary assessment application. A sample of 21 older Koreans aged 65 years and more was recruited from a community center. The 4-week data were collected for each participant (n = 19) using self-report questionnaires, wearable devices, and interviews and were analyzed using mixed methods. The depressive group (n = 6) indicated lower user acceptance relative to the nondepressive group (n = 13). Both groups experienced positive emotions, had regular life patterns, increased their self-interest, and stated that a system could disturb their daily activities. However, they were interested in learning new technologies and actively monitored their mental health status. Our multimodal monitoring system shows potential as a feasible and useful measure for acquiring mental health information about geriatric depression.

Effects of Physical Activity Interventions in the Elderly with Anxiety, Depression, and Low Social Support: A Clinical Multicentre Randomised Trial

The percentage of older people is increasing worldwide. Loneliness and anxious−depressive states are emerging health conditions in this population group, and these conditions give rise to higher morbidity and mortality. Physical activity (PA) and social relationships have been linked to physical and mental health. The objective of this study was to evaluate whether a 4-month programme of moderate PA in a group would improve the emotional state, levels of social support, and quality of life in a sample of individuals >64 years of age. A multicentre randomised clinical trial was designed in primary care. Ninety (90) participants were selected. After the intervention, there were positive differences between the groups, with significant improvements in the intervention group (IG) in depression, anxiety, health status perception, and social support. Walking in a group two days per week for 4 months reduced clinical depression and anxiety by 59% and 45%, respectively. The level of satisfaction was very high, and adherence was high. In conclusion, the moderate group PA programme improved clinical anxiety, depression, social support, and perceptions of health status in the patients studied.

The effects of leisure time physical activity on depression among older women depend on intensity and frequency

BACKGROUND

Leisure time physical activity (LTPA) is beneficial for late-life depression (LLD). The main purpose of this study was to estimate the associations between LTPA parameters (intensity, duration, frequency) and LLD.

METHODS

Through the 2018 Women Health Needs Survey, data on 1,892 women aged 55-70 in Hunan, China, were studied. Depression was measured by the 9-item Patient Health Questionnaire (PHQ-9). Self-reported LTPA parameters were collected. Binary logistic regression models were used to compute odds ratios (OR) for LTPA for predicting depression. Sensitivity analyses were conducted to examine the effect of missing values.

RESULTS

Moderate LTPA volume (OR = 0.582, p = 0.027, 95% CI [0.360-0.941] for 150-299 min/week and OR = 0.392, p = 0.002, 95% CI [0.215-0.714] for ≥300 min/week) was associated with reduced depression, while vigorous LTPA could increase the risk (OR = 2.414, p = 0.029, 95% CI [1.095-5.325] for <75 min/week and OR = 3.824, p = 0.007, 95% CI [1.439-10.158] for ≥75 min/week). Frequent (6-7 days/week), moderate LTPA had a lower risk (OR = 0.570, p = 0.021, 95% CI [0.353-0.918]), while frequent (≥3 days/week), vigorous LTPA increased the risk (OR = 5.103, p = 0.001, 95% CI [1.977-13.172]). The adjusted relationship between the duration and depression was not observed. The results were supported by the sensitivity analysis based on missing value replacement.

LIMITATIONS

In this cross-sectional study, LTPA data were self-reported and no data on light LTPA were collected.

CONCLUSIONS

Moderate LTPA, associated with mental health benefits, should be recommended for older women instead of vigorous LTPA.

Light-intensity physical activity and mental ill health: a systematic review of observational studies in the general population

Background

Most of theevidence has focused on examining the influence of moderate-to-vigorous intensity physical activity on mental health, but he role of light intensity physical activity (LIPA) is less understood. The purpose of this systematic review was to assess the relationship between time spent in LIPA and mental ill health across the lifespan.

Methods

Data were obtained from online databases (Medline, Embase, Scopus, PsychInfo and CINAHL). The search and collection of eligible studies was conducted up to May 28, 2020. Observational studies conducted in the general population and reporting on the association between LIPA (1.6–2.9 metabolic equivalents; either self-reported or device-based measured) and mental ill health were included.

Results

Twenty-two studies were included in the review (16 cross-sectional and 6 longitudinal). In older adults (≥ 65 years) and adults (18–64 years), the evidence examining the relationship between LIPA and depressive symptoms is mixed. Data on anxiety, psychological distress and overall mental health are scarce, and results are inconclusive. There is no evidence suggesting favorable associations between LIPA and anxiety in college students. Finally, very limited data was found in adolescents (11–17 years) (n = 2 studies) and children (6–10 years) (n = 2 studies), but the evidence suggests that LIPA does not influence mental health outcomes in these age groups.

Conclusions

This review provided mostly cross-sectional evidence indicating that LIPA may not be associated with mental health outcomes across age groups. Future research efforts employing prospective research designs are warranted to better understand the role of LIPA on mental ill health across age groups.

Physical activity, emotional state and socialization in the elderly: study protocol for a clinical multicentre randomized trial

OBJECTIVE

To evaluate whether a 4-month physical activity (PA) group program and visits to sociocultural organizations improve emotional state, social support levels and health-related quality of life in elderly individuals with depression and/or anxiety and/or loneliness.

METHODS

This will be a multicentre, randomized, two-group clinical trial with a 1-year follow-up. Participants will be 150 primary care patients aged >64 years allocated equally to a control group and an intervention group. Inclusion criteria are Beck Depression Inventory (BDI-II) score ≥14 and/or General Anxiety Disorder (GAD-7) scale score ≥10 and/or Duke-UNC-11 scale score ≥32. The intervention group will participate in a 4-month group PA program. The program will comprise two walks per week and a monthly visit to a sociocultural facility.

RESULTS

Measured outcomes are clinical remission of depression (BDI-II score <14) and anxiety (GAD-7 scale score <10), improved social support (reduction in DUKE-UNC-11 score), improved quality of life and/or response to the intervention at 4 and 12 months post-intervention. Intervention satisfaction and adherence and post-intervention links with sociocultural organizations will also be assessed.

CONCLUSION

The findings could encourage the provision of activity-based community interventions for older individuals.

The Effect of Labor and Relationship Exclusions on Older Korean Men with Depression

To manage depression of older men, it is necessary to identify factors that influence depression and improve them. This study used the Korean Aging Longitude Research to understand the effects of labor exclusion and relationship exclusion on depression in Korean male seniors aged 65 and older. According to research on the effect of labor exclusion and relationship exclusion on depression, depression in the case where labor was excluded was 1.69 times higher in 2014, 1.65 times higher in 2016, and 1.93 times higher in 2018 compared to the case where labor was not excluded. Depression in the case where relationship was excluded was 2.94 times higher in 2014, 3.15 times higher in 2016, and 2.57 times higher in 2018 compared to the case where relationship was not excluded. Depression in the case where labor and relationship were both excluded was 3.00 times higher in 2014, 3.23 times higher in 2016, and 2.81 times higher in 2018 compared to the case where neither labor nor relationship was excluded. Since labor exclusion and relationship exclusion have a big influence on depression in older men, it is necessary to establish plans for job creation and for the formation of social relationships for the elderly.

Cross-sectional and longitudinal associations of outdoor walking with overall mental health in later life

PURPOSE

This study aimed to examine the cross-sectional and longitudinal associations of three walking parameters (frequency, duration, and intensity) with overall mental health in older adults.

METHODS

A cross-sectional survey was conducted in 2014 with 1255 community-dwelling older adults aged 65 years and older in Taipei, Taiwan. Among them, 408 participants completed the one-year follow-up survey in 2015. Self-reported outdoor walking during the past 7 days was measured by asking the frequency, duration, and intensity. Metabolic equivalent (MET) values (<2.5, 2.5-<3.5, 3.5-<4.5, and ≥4.5 MET) were assigned to the four levels of speed (slow pace, average, brisk, and fast pace) based on the average walking distance per minute. Overall mental health was assessed using the Five-item Brief Symptom Rating Scale (BSRS-5). Multivariable linear regression models were conducted to explore the cross-sectional and longitudinal associations between outdoor walking and overall mental health, adjusting for socio-demographic factors, lifestyle behaviors, comorbidity and health status.

RESULTS

Among the walking parameters, only walking intensity emerged as a significant predictor of subsequent overall mental health. Multivariable regression analysis showed that light-to-moderate intensity (approximately 2.5-<4.5 METs) was significantly associated with better overall mental health at 12-month follow-up.

CONCLUSIONS

Outdoor walking at light-to-moderate intensity is prospectively associated with better overall mental health in later life.

Combining Web-Based Gamification and Physical Nudges With an App (MoveMore) to Promote Walking Breaks and Reduce Sedentary Behavior of Office Workers: Field Study

Background

Sedentary behavior (SB) and lack of physical activity (PA) have been associated with poorer health outcomes and are increasingly prevalent in individuals working in sedentary occupations such as office jobs. Gamification and nudges have attracted attention as promising strategies to promote changes in health behavior. However, most effectiveness studies thus far lacked active controls, and few studies have tested interventions combining these strategies.

Objective

This study investigates the effectiveness of combining a gamified digital app with physical nudges to increase PA and reduce SB in Dutch office workers.

Methods

Employees in the municipality of Rotterdam (N=298) from two office locations were randomized at the location level to either a 10-week intervention, combining a 5-week gamification phase encompassing a gamified digital app with social support features and a 5-week physical nudges phase, or to an active control (ie, basic digital app with self-monitoring and goal setting). The primary outcome was the daily step count, objectively measured via accelerometers. Secondary outcomes were self-reported PA and SB measured at baseline and at 5, 10, and 14 weeks. Mixed effects models were used to analyze the effects of the intervention on the outcome measures.

Results

A total of 78.5% (234/298) of participants completed the study and provided accelerometer data, whereas 36.9% (110/298) participants completed the self-report measures at 14 weeks. In the gamification phase, step count data were missing for 13.5% (473/3492) of observations in the control and 11.4% (445/3888) in the intervention condition; however, these percentages increased to 39.6% (1154/2910) and 59.6% (1932/3492) at follow-up, respectively. During the gamification phase, intervention participants increased their number of daily steps by 634 (95% CI 154.2-1113.8; P=.01) more than participants in the control group, after controlling for relevant factors. Improvements were not sustained during the physical nudges phase (P=.76) or follow-up (P=.88).

Conclusions

A digital intervention with gamification and social support features significantly increased the step count of office workers compared with an active control. Physical nudges in the workplace were insufficient to promote the maintenance of behavioral changes achieved in the gamification phase. Future research should explore the long-term effectiveness of similar gamified digital interventions.

Differences in objectively measured daily physical activity patterns related to depressive symptoms in community dwelling women - mPED trial

Physical activity (PA) is an effective depression treatment. However, knowledge on how variation in day-to-day PA relates to depression in women is lacking. The purposes of this study were to 1) compare overall objectively measured baseline daily steps and duration of moderate to vigorous PA (MVPA) and 2) examine differences in steps and MVPA on days of the week between women aged 25–65 years, who were physically inactive, with high and low depressive symptoms, enrolled in a run-in period of the mobile phone based physical activity education (mPED) trial. The Center for Epidemiological Studies Depression Scale was used to categorize low/high depressive symptom groups. We used linear mixed-effects models to examine the associations between steps and MVPA and depression-status overall and by day of the week, adjusting for selected demographic variables and their interactions with day of the week. 274 women were included in the final analysis, of which 58 had high depressive symptoms. Overall physical activity levels did not differ. However, day of the week modified the associations of depression with MVPA (p = 0.015) and daily steps (p = 0.08). Women with high depression were characterized by reduced activity at the end of the week (Posthoc: Friday: 791 fewer steps, 95% CI: 73–1509, p = 0.03; 8.8 lower MVPA, 95% CI: 2.16–15.5, p = 0.0098) compared to women with low depression, who showed increased activity. Day of the week might be an important target for personalization of physical activity interventions. Future work should evaluate potential causes of daily activity alterations in depression in women.

Accelerometer-derived sedentary time and physical activity and the incidence of depressive symptoms - The Maastricht Study

BACKGROUND

This study examined the associations between accelerometer-derived sedentary time (ST), lower intensity physical activity (LPA), higher intensity physical activity (HPA) and the incidence of depressive symptoms over 4 years of follow-up.

METHODS

We included 2082 participants from The Maastricht Study (mean ± s.d. age 60.1 ± 8.0 years; 51.2% men) without depressive symptoms at baseline. ST, LPA and HPA were measured with the ActivPAL3 activity monitor. Depressive symptoms were measured annually over 4 years of follow-up with the 9-item Patient Health Questionnaire (PHQ-9). Cox regression analysis was performed to examine the associations between ST, LPA, HPA and incident depressive symptoms (PHQ-9 ⩾ 10). Analyses were adjusted for total waking time per day, age, sex, education level, type 2 diabetes mellitus, body mass index, total energy intake, smoking status and alcohol use.

RESULTS

During 7812.81 person-years of follow-up, 203 (9.8%) participants developed incident depressive symptoms. No significant associations [Hazard Ratio (95% confidence interval)] were found between sex-specific tertiles of ST (lowest v. highest tertile) [1.13 (0.76-1.66], or HPA (highest v. lowest tertile) [1.14 (0.78-1.69)] and incident depressive symptoms. LPA (highest v. lowest tertile) was statistically significantly associated with incident depressive symptoms in women [1.98 (1.19-3.29)], but not in men (p-interaction <0.01).

CONCLUSIONS

We did not observe an association between ST or HPA and incident depressive symptoms. Lower levels of daily LPA were associated with an increased risk of incident depressive symptoms in women. Future research is needed to investigate accelerometer-derived measured physical activity and ST with incident depressive symptoms, preferably stratified by sex.

An Exploratory Study of the Relative Effects of Various Protective Factors on Depressive Symptoms Among Older People

Objective: The present study investigated the relative importance of various factors found to be negatively associated with depressive symptoms in older adults and assessed the potential moderating effect of sociodemographic characteristics for each factor.

Method: Depressive symptoms were measured with the Center of Epidemiological Studies Depression Scale. Psychological, social, and physical health measures relating to the following factors were also administered: personal growth, purpose in life, self-esteem, self-efficacy, social support, self-rated health, life satisfaction, and physical activity. Multivariate linear regression analysis was used to investigate the most important factors associated with depressive symptoms, and moderation analyses were employed to identify any moderating effects of sociodemographic factors.

Results: Life satisfaction, self-esteem, and purpose in life were found to be negatively associated with depressive symptoms. Only one moderating effect was observed—the negative relationship between life satisfaction and depressive symptoms was significantly stronger among the younger respondents.

Conclusion: These findings suggest that strategies for the prevention or amelioration of depressive symptoms across subgroups of the senior population could be optimized by focusing on enhancing life satisfaction, self-esteem, and purpose in life.

The Effectiveness of an Active Learning Program in Promoting a Healthy Lifestyle among Older Adults with Low Health Literacy: A Randomized Controlled Trial

BACKGROUND

Older adults often have a greater need for health information and health care services because access to these helps them manage their health and the chronic conditions of aging. Therefore, low health literacy bears a special significance for the population of older adults.

OBJECTIVES

The aim of this study was to examine the effects of an active learning program on health literacy, lifestyle behaviors, physical function, and mental health among community-dwelling older adults with low health literacy.

METHODS

This single-blind, randomized controlled trial involved 60 participants aged ≥65 years with a low health literacy who were randomly assigned to an intervention (n = 30) or control (n = 30) group. Across 24 weeks, the intervention group attended weekly 90-min active learning program sessions, which involved exploratory learning, group work, and the self-planning of behavior changes that promote a healthy lifestyle. The control group attended a 90-min class, which was taught in accordance with the didactic teaching method. For both groups, the programs focused on the role of exercise, diet/nutrition, and cognitive activity for promoting health among older adults. The outcome measures were administered at baseline and week 24. Comprehensive health literacy (i.e., primary outcome) was assessed using the Health Literacy Scale-14. Lifestyle factors (i.e., physical activity, dietary variety, life-space mobility, and social network size), physical function, and depressive symptoms were measured. We used a linear mixed model to estimate the intervention effects in accordance with the intention-to-treat approach.

RESULTS

When compared to the control group, the intervention group demonstrated a significant improvement in communicative health literacy, step count, engagement in moderate-to-vigorous physical activity, dietary variety, life-space mobility, social network size, grip strength, gait speed, and depressive symptoms.

CONCLUSIONS

The active learning program can promote a healthy lifestyle and prevent functional decline among older adults who lack the confidence to engage in health communication.

Important Elements and Features of Neighborhood Landscape for Aging in Place: A Study in Hong Kong

With rapid growth in the aging population around the world, the promotion of aging in place has become more significant in recent years. Many neighborhood landscape elements and features have been revealed by accumulating research findings to be critical to aging in place. However, they are usually studied separately or in small groups. Little has been done to examine the relative importance of these elements and features when brought together, from the older adult's point of view. In this context, the current study investigated the perceived importance for older adults of 22 selected neighborhood landscape elements and features. A questionnaire survey was conducted in 17 public rental housing estates in Hong Kong with proportions of older residents (aged 65 or above) between 20 and 40%. According to the 426 collected samples, older adults considered as highly important landscape elements and features that contribute to comfort and help them avoid hazards, such as good ventilation, protection from severe sunshine/rain, body support, and good hygiene, while elements were thought to potentially bring hazards while not being necessities for older adults' outdoor experience were considered least important, including portable chairs, outdoor tables, plants that can be touched, closeness to children's playgrounds, small spaces for solitude, water features, and fitness equipment. After integrally interpreting the findings regarding perceived importance with other collected data, some landscape design suggestions are generated to supplement existing guidelines and recommendations concerning older adults' well-being and quality of life. These findings can inspire future research and landscape design that prioritize promoting aging in place.

Considerations in Processing Accelerometry Data to Explore Physical Activity and Sedentary Time in Older Adults

Processing decisions for accelerometry data can have important implications for outcome measures, yet little evidence exists exploring these in older adults. The aim of the current study was to investigate the impact of three potentially important criteria on older adults, physical activity, and sedentary time. Participants (n = 222: mean age 71.75 years [SD = 6.58], 57% male) wore ActiGraph GT3X+ for 7 days. Eight data processing combinations from three criteria were explored: low-frequency extension (on/off), nonwear time (90/120 min), and intensity cut points (moderate-to-vigorous physical activity ≥1,041 and >2,000 counts/min). Analyses included Wilcoxon signed-rank test, paired t tests, and correlation coefficients (significance, p < .05). Results for low-frequency extension on 90-min nonwear time and >1,041 counts/min showed significantly higher light and moderate-to-vigorous physical activity and lower sedentary time. Cut points had the greatest impact on physical activity and sedentary time. Processing criteria can significantly impact physical activity and/or sedentary time, potentially leading to data inaccuracies, preventing cross-study comparisons and influencing the accuracy of population surveillance.

Depression and Objectively Measured Physical Activity: A Systematic Review and Meta-Analysis

Depression is a major contributor to the overall global burden of disease, with high prevalence and relapse rate. Several factors have been considered in order to reduce the depression burden. Among them, physical activity (PA) showed a potential protective role. However, evidence is contrasting probably because of the differences in PA measurement. The aim of this systematic review with meta-analysis is to assess the association between objectively measured PA and incident and prevalent depression. The systematic review was conducted according to methods recommended by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant papers published through 31 August 2019 were identified searching through the electronic databases PubMed/MEDLINE, Excerpta Medica dataBASE (Embase), PsycINFO, Scopus, Web of Science (WoS), and the Cochrane Library. All analyses were conducted using ProMeta3. Finally, 42 studies met inclusion criteria. The overall Effect size (ES) of depression for the highest vs. the lowest level of PA was −1.16 [(95% CI = −1.41; −0.91), p-value < 0.001] based on 37,408 participants. The results of the meta-analysis showed a potential protective effect of PA on prevalent and incident depression.

Exercise and Depressive Disorder

Depression is a psychiatric disorder characterized by low mood, loss of interest/enjoyment, and reduced energy and one of the five leading causes of disability and a major contributor to all-cause mortality worldwide. People with depression have, between others, a reduced life expectancy, worse quality of life and cardiorespiratory fitness, and increased risk of type 2 diabetes, compared to the general population. Furthermore, the economic burden of mental disorders including depression is evident, and it is expected to increase to more than double by 2030. Therefore, reducing the growing burden of mental disorders such as depression should be a health priority. Improved prevention and treatment are two key factors that may reduce the burden of depression. Pharmacological- and psychotherapy-based interventions have been traditionally considered for treating depression disorders; however, there is an increasing amount of scientific evidence confirming that physical activity and physical exercise should be highly considered in prevention and treatment of depressive disorders. In this chapter, we aim to summarize and discuss the research progress of physical activity and exercise in prevention and treatment of depressive disorder. Specifically, we summarized and discussed the research progress of the prognostic use of physical activity for incident depression, the importance of sedentary behavior and other outcomes typically improved by physical activity/exercise such as cardiorespiratory fitness for future depression, the research progress of the evidence of the benefits of exercise in people with depression disorders, the resistance training effects in adults and older adults with depression, and the recommendations for the prescription of exercise for people with depression.

Isotemporal substitution modeling on sedentary behaviors and physical activity with depressive symptoms among older adults in the U.S.: The national health and nutrition examination survey, 2007-2016

BACKGROUND

Late-life depression is a great burden of public health. Previous studies reported that physical activity is associated with reduced depressive symptoms among older adults, while the competing nature of physical activity and sedentary behaviors has been largely neglected in studies. We aimed to examine the associations of replacing sedentary behaviors with walking/bicycling or moderate-to-vigorous physical activity (MVPA) with depressive symptoms in older adults.

METHODS

A cross-sectional analysis was conducted among 8374 older adults (60 years or older) included in the National Health and Nutrition Examination Survey (NHANES), 2007-2016. The Global Physical Activity Questionnaire was used to measure self-reported time for sedentary behaviors, walking/bicycling, and MVPA. The 9-item Patient Health Questionnaire was used to measure depressive symptoms (including overall, somatic, and cognitive). Z-scores were created for depressive symptoms. Isotemporal substitution models using multivariable linear regression were applied to examine the associations of sedentary behaviors, walking/bicycling, and MVPA with z-scores of depressive symptoms.

RESULTS

Replacing 30 min/day sedentary behaviors with 30 min/day of MVPA (beta (β) = -0.10, 95% confidence interval (CI): -0.14, -0.06) or 30 min/day of walking/bicycling (β = -0.04, 95% CI: -0.06, -0.02) was associated with lower z-score for depressive symptoms. Replacing 30 min/day of walking/bicycling for 30 min/day of MVPA was associated with lower z-score for depressive symptoms (β = -0.06, 95% CI: -0.10, -0.02).

LIMITATIONS

A cross-sectional study design precludes causal inferences.

CONCLUSION

Replacing sedentary behaviors with walking/bicycling or MVPA is associated with lower depressive symptoms among older adults. Future research is expected to investigate the effectiveness of physical activity on prevention and treatment of late-life depression.

Change in physical activity and health-related quality of life in old age-A 10-year follow-up study

The aim of the study was to examine the association between change in leisure-time physical activity (LTPA) and change in health-related quality of life (HRQoL) and symptoms of depression during a 10-year follow-up. This prospective study included 1036 men and women (mean age at baseline = 61.2 years) from the Helsinki Birth Cohort Study. Leisure-time physical activity was measured with a questionnaire, HRQoL with SF36 and depression symptoms with Beck's depression inventory (BDI). The association between the change in LTPA and change in HRQoL and BDI were investigated with sex-stratified general linear models adjusted for age, smoking, educational attainment, comorbidity score, and baseline value of outcomes. One standard deviation (SD) increase in LTPA was associated with increase in physical summary component of HRQoL in women (B = 0.7 unit, 95% CI = 0.1-1.3, P = 0.032) and in men (B = 0.8 unit, 95% CI = 0.2-1.5, P = 0.014). In women, the 1SD increase in LTPA was also associated with an increase in mental summary component score (B = 1.0, 95% CI = 0.3-1.7, P = 0.005) and a reduction in depressive symptoms (B = -0.7, 95% CI = -1.1 to -0.2, P = 0.003). In conclusion, increase in the volume of LTPA over a 10-year period in late adulthood was associated with improved HRQoL in both men and women, and also diminished depressive symptoms in women. The findings support the promotion of physical activity in later years to enhance HRQoL and mental well-being.

Association between health behaviors and mood disorders among the elderly: a community-based cohort study

BACKGROUND

According to a WHO report, nearly 15% of adults aged 60 and over suffer from a mental disorder, constituting 6.6% of the total disability for this age group. Taipei City faces rapid transformation towards an aging society, with the proportion of elderly in the total population rising from 12% in 2008 to 16% in 2016. The aim of this study is to identify the prevalence of mental disorders among the elderly in Taipei City and to elucidate risk factors contributing to mental disorders.

METHODS

The elderly health examination database was obtained from the Department of Health, Taipei City government, from 2005 to 2012. A total of 86,061 people underwent publicly funded health examinations, with 348,067 visits. Each year, there are around 43,000 elderly persons in Taipei City using this service. We used a mental health questionnaire including five questions to estimated relative risks among potential risk factors with the generalized estimating equations (GEE) model to measure the mental health status of the elderly. Mood disorders were measured with the Brief Symptom Rating Scale (BSRS-5) questionnaire. Age, education level, gender, marital status, living alone, drinking milk, eating vegetables and fruits, long-term medication, smoking status, frequency of alcohol consumption, frequency of physical activity, BMI, and number of chronic diseases were included as covariates.

RESULTS

The results show that being male (odds ratio (OR) 0.57; 95% CI = 0.56, 0.59), higher education (OR 0.88; 95% CI = 0.82, 0.95), no long-term medication (OR 0.57; 95% CI = 0.56, 0.58), and exercising three or more times per week (OR 0.94; 95% CI = 0.91, 0.98) were all positively correlated with better emotional status. However, being divorced (OR = 1.22, 95% CI = 1.09, 1.36), not drinking milk (OR = 1.12, 95% CI = 1.09, 1.14), not eating enough vegetables and fruits every day (OR = 1.78, 95% CI = 1.73, 1.83), daily smoking (OR = 1.15, 95% CI = 1.01, 1.32), and having more chronic diseases (OR = 1.02, 95% CI = 1.01, 1.03) were all correlated with poor mental status among the elderly.

CONCLUSIONS

The findings of this research can both estimate the prevalence of mood disorders at the community level, and identify risk factors of mood disorders at the personal level.

Exploring Factors Associated With Physical Activity in Older Adults: An Ecological Approach

According to ecological models of behavior, the physical environment can influence physical activity engagement by a series of mediating and moderating processes. This study tested such a model to identify factors relevant to older adults' engagement in moderate-vigorous physical activity. Sociodemographic, psychological, physical, and environmental factors were assessed in 432 Western Australians aged 60 and older. Moderate-vigorous physical activity was measured objectively using accelerometers. No environmental variables were related to engagement in moderate-vigorous physical activity either directly or indirectly. However, various individual-level factors were significant, indicating that these may be more important than environmental factors in locations such as Australia that have generally conducive environments and ambient conditions.
