Cardiovascular Health Is Associated With Physical Function Among Older Community Dwelling Men and Women

Does Incident Cardiovascular Disease Lead to Greater Odds of Functional and Cognitive Impairment? Insights From the Health and Retirement Study

BACKGROUND

Although studies to date have broadly shown that cardiovascular disease (CVD) increases cognitive and physical impairment risk, there is still limited understanding of the magnitude of this risk among relevant CVD subtypes or age cohorts.

METHODS

We analyzed longitudinal data from 16 679 U.S. Health and Retirement Study participants who were aged ≥65 years at study entry. Primary endpoints were physical impairment (activities of daily living impairment) or cognitive impairment (Langa-Weir Classification of dementia). We compared these endpoints among participants who developed incident CVD versus those who were CVD free, both in the short term (<2-year postdiagnosis) and long term (>5 years), controlling for sociodemographic and health characteristics. We then analyzed the effects by CVD subtype (atrial fibrillation, congestive heart failure, ischemic heart disease, and stroke) and age-at-diagnosis (65-74, 75-84, and ≥85).

RESULTS

Over a median follow-up of 10 years, 8 750 participants (52%) developed incident CVD. Incident CVD was associated with significantly higher adjusted odds (aOR) of short-term and long-term physical and cognitive impairment. The oldest (≥85) age-at-diagnosis subgroup had the highest risk of short-term physical (aOR 3.01, 95% confidence interval [CI]: 2.40-3.77) and cognitive impairment (aOR 1.96, 95% CI: 1.55-2.48), as well as long-term impairment. All CVD subtypes were associated with higher odds of physical and cognitive impairment, with the highest risk for patients with incident stroke.

CONCLUSIONS

Incident CVD was associated with an increased risk of physical and cognitive impairment across CVD subtypes. Impairment risk after CVD was highest among the oldest patients (≥85 years) who should therefore remain a target for prevention efforts.

Cardiovascular health profiles, systemic inflammation, and physical function in older adults: A population-based study

We examined the association of modifiable cardiovascular health (CVH) metrics with physical function among rural older adults in China and the potential role of inflammatory mechanisms in the association. This study included 3733 stroke- and dementia-free participants (age ≥65 years; 56.9% women) in the baseline survey of a multimodal intervention study in rural China. From March-September 2018, data were collected via face-to-face interviews, clinical assessments, and laboratory tests. The Short Performance Physical Battery (SPPB) test was performed to assess physical function. We defined six modifiable CVH metrics according to the modified American Heart Association's recommendations. Serum interleukin (IL)-6 was measured in a subsample (n = 1156). Data were analyzed with multiple general linear and logistic regression models and structural equation modeling. Poor physical function (SPPB score ≤9) was defined in 1443 participants. Ideal CVH (vs. poor CVH) was associated with multivariable-adjusted odds ratio of 0.60 (95%CI 0.48-0.75) for poor physical function. Ideal CVH was significantly associated with higher scores on balance, chair stand, and walking speed tests (all p < 0.05). Moreover, ideal CVH profile was associated with lower serum IL-6 (multivariable-adjusted β=-0.04; 95% CI -0.06, -0.01). Mediation analysis revealed that serum IL-6 accounted for 14% of the association of CVH with total SPPB score and 10% of the association with walking speed score (p < 0.05). This study suggests that an ideal CVH profile is associated with better physical function among stroke- and dementia-free older adults, partly via inflammatory mechanisms. The preventive implications of these findings warrant further investigation in cohort studies.

Proteomic Mediators of Overall Cardiovascular Health on All-Cause Mortality

Measures of cardiovascular health (CVH) assessed by a combination of behavioral and biological factors has shown protective associations with all-cause mortality. The mechanisms underlying these associations have not been fully elucidated. In this study, we characterized the plasma proteomics profile of CVH and tested whether specific proteins mediated the associations between CVH and all-cause mortality in participants of the InCHIANTI study. Of the 1301 proteins tested, 92 proteins were associated with CVH (22 positively, 70 negatively). Proteins most strongly associated with CVH included leptin (LEP), fatty acid binding protein 3 (FABP3), Angiopoietin-2 (ANGPT2), and growth-differential factor 15 (GDF15). Of the 92 CVH-associated proteins, 33 proteins significantly mediated the associations between CVH and all-cause mortality, with percent mediation ranging from 5 to 30%. The most significant mediating proteins were GDF15 and insulin-like growth factor 2 (IGFBP2). Proteins associated with better CVH were enriched for proteins that reflect the suppression of the complement coagulation and GH/IGF pathways.

High Adherence to the Mediterranean Diet is Associated with Higher Physical Fitness in Adults: a Systematic Review and Meta-Analysis

Although prior research has synthesized the relationships between the Mediterranean diet (MD) and components of physical fitness (PF) in adults, they are limited and inconclusive. This study aimed to synthesize the associations between high (compared with low) MD adherence and PF levels with each of its components (cardiorespiratory, motor, and musculoskeletal) in adulthood. We conducted a systematic search in 5 databases from inception to January 2022. Observational studies and randomized controlled trials were included. Pooled odds ratios (ORs) and effect sizes (Cohen d index) with their 95% CIs were calculated via a random effects model. A total of 30 studies were included (19 cross-sectional in young, middle-aged, and older adults; 10 prospective cohort in older adults; and 1 randomized controlled trial in young adults) involving 36,807 individuals (mean age range: 20.9-86.3 y). Pooled effect sizes showed a significant cross-sectional association between higher MD adherence scores (as a continuous variable) and overall PF (d = 0.45; 95% CI: 0.14, 0.75; I2 = 91.0%, n = 6). The pooled ORs from cross-sectional data showed that high adherence to MD was associated with higher cardiorespiratory fitness (OR: 2.26; 95% CI: 2.06, 2.47; I2 = 0%, n = 4), musculoskeletal fitness (OR: 1.26; 95% CI: 1.05, 1.47; I2 = 61.4%, n = 13), and overall PF (OR: 1.44; 95% CI: 1.20, 1.68; I2 = 83.2%, n = 17) than low adherence to MD (reference category: 1). Pooled ORs from prospective cohort studies (3- to 12-y follow-up) showed that high adherence to MD was associated with higher musculoskeletal fitness (OR: 1.20; 95% CI: 1.01, 1.38; I2 = 0%, n = 4) and overall PF (OR: 1.14; 95% CI: 1.02, 1.26; I2 = 9.7%, n = 7) than low adherence to MD (reference category: 1). Conversely, no significant association was observed between MD and motor fitness. High adherence to MD was associated with higher PF levels, a crucial marker of health status throughout adulthood. This trial was registered at PROSPERO as CRD42022308259.

Midlife Cardiovascular Health and Robust versus Frail Late-Life Status: The Atherosclerosis Risk in Communities (ARIC) Study

BACKGROUND

We examined the relationship of midlife cardiovascular health (CVH) with late-life robustness among men and women and the impact of survivorship bias on sex-differences in robustness.

METHODS

Prospective analysis of 15,744 participants aged 45-64 (Visit 1 median age: 54 years, 55% female, 27% Black) in 1987-1989 from the population-based ARIC Study. CVH was operationalized according to the Life's Simple 7 (LS7) metric of health behaviors (smoking, weight, physical activity, diet, cholesterol, blood pressure, and glucose); each behavior was scored as ideal (2 points), intermediate (1 point), or poor (0 points) and summed. Late-life robust/pre-frail/frailty was defined at Visit 5 (2011-2013). Multinomial regression estimated relative prevalence ratios (RPR) of late-life robustness/pre-frailty/frailty/death across overall midlife LS7 score and components, for the full Visit 1 sample. Separate analyses considered Visit 5 survivors only.

RESULTS

For each one-unit greater midlife LS7 score, participants had a 37% higher relative prevalence of being robust versus frail (overall RPR=1.37, [95% CI: 1.30-1.44]; women=1.45 [1.36-1.54]; men=1.24 [1.13-1.36]). Among the full Visit 1 sample, women had a similar one-level higher robustness category prevalence (RPR=1.35 [95% CI: 1.32-1.39]) than men (RPR=1.31 [95% CI: 1.27-1.35]) for every one-unit higher midlife LS7 score. Among survivors, men were more likely to be robust than women at lower LS7 levels; differences were attenuated and not statistically different at higher midlife LS7 levels.

CONCLUSIONS

Midlife CVH is positively associated with robustness in late-life among men and women. Accounting for mortality in part explains documented sex-differences in robustness across all levels of LS7.

Recovery From Mobility Limitation in Middle-Aged African Americans: The Jackson Heart Study

BACKGROUND

Despite evidence that African Americans shoulder a high burden of mobility limitation, little is known about factors associated with recovery.

METHOD

Participants from the Jackson Heart Study underwent 3 in-person exams from 2000 to 2013. Mobility limitations were assessed over this period by self-reported limitations in walking half a mile or climbing stairs during annual phone calls. The outcome of interest, recovery from mobility limitation, was defined as no mobility limitation the year following an incident event. Candidate predictor variables were assessed in logistic regression models, including sociodemographic, psychosocial, and health measures. Inverse probability weights were used to address missing data in the outcome.

RESULTS

Among 4526 participants (mean [SD] age = 54.5 (12.8) years) without a mobility limitation at baseline, 1445 (32%) had an incident mobility limitation over 12 years of follow-up, and 709 (49%) reported recovery from mobility limitation by 1 year later. Low income and daily discrimination were associated with a lower likelihood of recovery even after adjustment for covariates. In adjusted models, greater comorbidity was associated with a lower likelihood of recovering (p-value for trend = .05). History of heart failure and cancer were associated with a lower likelihood of recovering from mobility limitation (OR: 0.52, 95% CI: 0.29, 0.94 and OR: 0.74, 95% CI: 0.55, 1.00). Adiposity, smoking status, and physical activity were not associated with recovery from mobility limitation.

CONCLUSION

Half of incident mobility limitations in this population of middle-aged African Americans were transient. Adverse sociodemographic factors and comorbidities were associated with lower likelihood of recovery.

Does a Multicomponent Exercise Program Improve Physical Fitness in Older Adults? Findings From a 5-Year Longitudinal Study

The objective was to assess the physical fitness of older adults participating in a 5-year multicomponent exercise program. The sample consisted of 138 older adults aged 60-93 years (70.4 ± 7.8 years) evaluated with the Senior Fitness Test (muscle strength, flexibility, balance, and cardiorespiratory fitness). The multicomponent program was carried out between the months of March and November of each year. Data were analyzed using generalized estimating equations (factor year: Year 1, Year 2, Year 3, Year 4, and Year 5; factor time: pretest and posttest) with Bonferroni's post hoc test. Participation in the multicomponent exercise program for 5 years (baseline pretest Year 1 and follow-up Year 5) improved lower and upper limb strength, lower limb flexibility, and balance and cardiorespiratory fitness, while upper limb flexibility was maintained. Year-by-year analysis revealed variable patterns for each fitness parameter. The results of this study show the potential benefits of implementing a long-term community-based exercise program.

Physical activity, sedentary behavior and functionality in older adults: A cross-sectional path analysis

Disability is negatively associated with the health of older adults, and it can be mediated by healthy lifestyles and behaviors throughout one's life. In this context, understanding the interrelationships between sedentary behavior, physical activity and functionality may assist in the implementation of effective public health actions. Thus, the aim of the present study was to investigate the relationships between both physical activity and sedentary behavior and functionality in older adults and the possible mediators. The variables analyzed were selected according to the content analysis of International Classification of Functioning, Disability and Health model, and included activity, participation, health conditions, body functions and structures, environmental factors and personal factors. 419 individuals participated in the study. Physical activity was directly associated with disability in instrumental activities of daily living (IADL), and the association was mediated by self-esteem, aerobic endurance, and agility/balance. Sedentary behavior was indirectly associated with IADL disability, and the association was mediated by aerobic resistance, nutritional status, and agility/balance. Regarding the basic activities of daily living (BADL), physical activity showed an indirect association mediated by aerobic resistance and IADL. The association of sedentary behavior with BADL was mediated by aerobic resistance and lower limb flexibility. These results reinforce the idea that functionality is multidimensional, and the mediating factors must be considered when strategies for promoting physical activity and reducing sedentary behavior are designed.

Barriers to eating are associated with poor physical function in older women

Older adults have physical and social barriers to eating but whether this affects functional status is unknown. We examined associations between eating barriers and physical function in the Women's Health Initiative (WHI). In 2012-14, a subset of alive and participating women (n = 5910) completed an in-home examination including the Short Physical Performance Battery (SPPB) (grip strength, balance, timed walking speed, chair stand). WHI participants complete annual mailed questionnaires; the 2013-14 questionnaire included items on eating alone, eating < two meals/day, dentition problems affecting eating, physical difficulties with cooking/shopping and monetary resources for food. Linear regression tested associations of these eating barriers with SPPB, adjusting for BMI, age, race/ethnicity, and medical multimorbidities. Over half (56.8%) of participants were ≥ 75 years, 98.8% had a BMI ≥ 25.0 kg/m2 and 66% had multimorbidities. Eating barriers, excluding eating alone, were associated with significantly lower total (all p < .001) and component-specific, multivariate-adjusted SPPB scores (all p < .05). Compared to no barriers, eating < two meals/day (7.83 vs. 8.38, p < .0002), dentition problems (7.69 vs. 8.38, p < .0001), inability to shop/prepare meals (7.74 vs. 8.38, p < .0001) and insufficient resources (7.84 vs. 8.37 p < .001) were significantly associated with multivariate-adjusted mean SPPB score < 8. Models additionally adjusting for Healthy Eating Index-2010 had little influence on scores. As barriers increased, scores declined further for grip strength (16.10 kg for 4-5 barriers, p = .001), timed walk (0.58 m/s for 4-5 barriers, p = .001) and total SPPB (7.27 for 4-5 barriers, p < .0001). In conclusion, in this WHI subset, eating barriers were associated with poor SPPB scores.

Effects of Whole Body Electromyostimulation on Physical Fitness and Health in Postmenopausal Women: A Study Protocol for a Randomized Controlled Trial

Background: Age-related problems such as chronic diseases, functional limitation and dependence, reduce the quality of life in the elderly, and increase public spending in health. It has been established that physical activity plays a fundamental role in the health of the elderly. The whole body electromyostimulation (WB-EMS) could be a successful methodology as high-intensity training to improve the physical fitness of older people. Methods: A minimum of 13 women between 55 and 70 years old will be randomized in two groups. The exercise with WB-EMS group (EX + WB-EMS) will conduct a resistance strength training program with superimposed WB-EMS while the exercise group (EX) will perform only resistance strength and aerobic training. Balance, strength, flexibility, agility, speed, and aerobic performance (EXERNET battery and progressive resistance test), as well as body composition, blood parameters and physical activity reporting (IPAQ-E) will be assessed to analyze the effects of whole body electromyostimulation in the physical fitness and the health in postmenopausal women. Discussion: Innovative and scientifically well-designed protocols are needed to enhance the knowledge of the body's responses within this training methodology which is being used by a big quantity of population. This trial will provide evidence on the effectiveness of whole-body electromyostimulation in physical fitness and health in elderly women.

Continence: Bowel and Bladder and Physical Function Decline in Women

Purpose of review

The purpose of this article is to review the various forms of incontinence, highlight their impact on older women, and to explore current literature regarding the link between physical activity, physical function, and incontinence.

Recent findings

Both urinary and fecal incontinence become more prevalent with age, and are associated with significant morbidity. In parallel, there is a well-established decline in physical function that occurs with age. Furthermore, incontinence has a bidirectional relationship with physical function decline. Given the known link between increasing physical activity and preserved physical function, there is an emerging body of literature seeking to determine whether increases in physical activity may also improve incontinence outcomes. We review some recent data on this topic.

Summary

Continence and physical function are two closely linked entities. Further research is needed to determine whether interventions that increase physical activity might result in improved continence outcomes.

Are Health Behaviors and Self-Rated Health Related to Cardiovascular Health and Functional Performance? Results from the Lookup 7+ Cross-Sectional Survey among Persons Aged 65+

OBJECTIVES

Cardiovascular health (CVH) and physical performance (PP) are key factors of successful ageing. This study investigated whether self-reported CVH behaviours and self-rated health (SRH) are related to ideal CVH and PP.

DESIGN

Cross-sectional survey.

SETTING

Public places in Italy (e.g. exhibitions, malls, health promotion campaigns), outside of conventional healthcare settings.

PARTICIPANTS

1415 community-living persons aged 65+ years (mean age 72.2 ± 5.4; 58.4% female).

MEASUREMENTS

Three ideal CVH behaviors [regular physical activity (PA), healthy diet, no smoking] and SRH (1 excellent - 4 poor) were assessed through a brief questionnaire. Four ideal CVH factors [iBMI ≤ 25 kg/m2, untreated random total blood cholesterol ≤200 mg/dl, absence of diabetes (untreated random blood glucose ≤200 mg/dl), untreated blood pressure (iBP) <140/90mmHg] and two ideal PP factors [grip strength (iGrip), 5-repetition chair-stand test <10 seconds (iStand)] were measured.

RESULTS

Adjusted for age and gender, regular PA was positively related to CVH factor score (β = 0.1; p = < .001), iBMI (OR = 1.8; 95% CI = 1.5-2.3), iBP (OR = 1.3; 95% CI = 1.1-1.6) and iStand (OR = 1.6; 95% CI = 1.3-2.1). Healthy diet was positively related to CVH factor score (β = 0.1; p = < .05) and iGrip (OR = 1.4; 95% CI = 1.1-1.8). Participants rating SRH as "good" (OR = 2.0; 95% CI = 1.1-3.9) and "not so good" (OR = 2.3; 95% CI = 1.2-4.5) met iDiabetes more often than those with poor SRH. Moreover, iStand (OR = 3.2; 95% CI = 1.6-6.6) and iGrip (OR = 4.2; 95% = CI 2.0-8.8) were more prevalent among participants with excellent SRH compared with those with poor SRH.

CONCLUSIONS

Physical activity, diet and self-rated health may provide quick and easy-to-assess metrics to identify persons aged 65+ years at risk of cardiovascular events and functional impairment, who could particularly benefit from engaging in health promotion programs.

Cardiovascular Health Is Associated With Disability Among Older Community Dwelling Men and Women

Objective: The aim of this study was to investigate whether an index of overall cardiovascular health (CVH) is associated with disability in older individuals. Method: Data on 925 participants of the InCHIANTI study (Invecchiare in Chianti, aging in the Chianti area, ≥65 years, 55% women) with median follow-up of 9 years were used. CVH score was assessed by smoking status, physical activity, body mass index, diet quality, blood pressure, plasma cholesterol, and fasting blood glucose. Disability was examined using instrumental activities of daily living (IADL disabilities >0 vs. 0) and activities of daily living (ADL disabilities >0 vs. 0). Generalized estimating equations and Cox models assessed relationships between baseline CVH with disability and worsening over 9 years. Results: A 1-point increase in the CVH score was associated with 23% and 17% of lower odds of ADL (p < .001) and IADL (p < .001) disability and was protective of worsening of disability over 9 years. Cox models demonstrated that a 1-point increase in CVH score was associated with lower hazards of both ADL (hazard ratio [HR] = 0.86, p = .005) and IADL (HR = 0.91, p = .007) disability. Discussion: Among older individuals, better CVH was associated with lower risk of disability and worsening over 9 years.

Midlife Cardiovascular Status and Old Age Physical Functioning Trajectories in Older Businessmen

OBJECTIVES

The associations between cardiovascular disease (CVD) risk and later physical functioning have been observed, but only a few studies with follow-up into old age are available. We investigated the association between cardiovascular status in midlife and physical functioning trajectories in old age.

DESIGN

Prospective cohort study.

SETTING

Helsinki Businessmen Study.

PARTICIPANTS

We studied white men born between 1919 and 1934 in the Helsinki Businessmen Study (HBS, initial n = 3490).

MEASUREMENTS

Three CVD status groups were formed based on clinical measurements carried out in 1974: signs of CVD (diagnosed clinically or with changes in ECG, chronic disease present or used medication, n = 563); healthy and low CVD risk (n = 593) and high CVD risk (n = 1222). Of them, 1560 men had data on physical functioning from at least one of four data collection waves between 2000-2010. Ten questions from the RAND-36 (SF-36) survey were used to construct physical functioning trajectories with latent class growth mixture models. Mortality was accounted for in competing risk models.

RESULTS

A five-class solution provided the optimal number of trajectories: "intact," "high stable," "high and declining," "intermediate and declining," and "consistently low" functioning. Compared with low CVD risk, high CVD risk in midlife decreased the risk of being classified into the intact (fully adjusted β = -3.98; standard error = 2.0; P = .046) relative to the consistently low physical functioning trajectory. Compared with low CVD risk, those with signs of CVD were less likely to follow the intact, high stable, or high and declining relative to the consistently low trajectory (all P < .018).

CONCLUSION

Among businessmen, a more favorable CVD profile in midlife was associated with better development of physical functioning in old age. J Am Geriatr Soc 67:2490-2496, 2019.

The many ages of man: diverse approaches to assessing ageing-related biological and psychological measures and their relationship to chronological age

PURPOSE OF REVIEW

Chronological age is a crude measure and may not be the best indicator of the ageing process. Establishing valid and reliable biomarkers to understand the true effect of ageing is of great interest. We provide an overview of biological and psychological characteristics that change with age and can potentially serve as markers of the ageing process, and discuss if an integration of these characteristics may more accurately measure the true age of a person. We also describe the clinicopathological continuum of these ageing-related changes.

RECENT FINDINGS

Ageing-related changes in the biological and psychological systems of the body have been studied to varying degrees and with differing emphases. Despite the development of ageing indices, there is no single indicator that can holistically estimate the ageing process. Differential ageing of bodily systems remains poorly understood, and valid methods have not been developed for composite markers of biological and psychological processes.

SUMMARY

The ageing process is complex and heterogeneous. Incorporating biological and psychological measures may improve accuracy in reflecting an individual's 'true age,' and elucidate why some people age successfully, whereas others show ageing-related decline and disease.

The Alternative Healthy Eating Index and Physical Function Impairment in Men

OBJECTIVES

Physical function is increasingly recognized as integral to healthy aging, in particular as a core component of mobility and independent living in older adults. Thus, it is important to identify strategies for the prevention of physical function decline.

DESIGN

Longitudinal cohort study.

SETTING AND PARTICIPANTS

A total of 12,658 men from the Health Professionals Follow-Up Study were followed from 2008-2012.

MEASUREMENTS

We examined the association between the Alternative Healthy Eating Index-2010 (AHEI), a measure of diet quality combining 11 dietary components (vegetables, fruits, nuts and legumes, red and processed meats, sugar-sweetened beverages and fruit juices, alcohol, whole grains, omega-3 fatty acids, polyunsaturated fatty acids, trans fatty acids, sodium), and impairment in physical function, as measured by the SF-36. Multivariable logistic regression models were used to estimate the odds ratios (OR) and 95% confidence intervals (CI) of impairment in physical function.

RESULTS

In the multivariable-adjusted model, each 10-point increase in total AHEI score was associated with a 10% lower odds of impairment in physical function (OR=0.90, 95% CI: 0.86,0.95), and in the categorical analysis, men with AHEI scores in the top quintile had a 26% lower odds (OR=0.74, 95% CI:0.63,0.86) compared with men in the bottom quintile. For individual AHEI components, higher intake of vegetables (p-trend=0.01), nuts and legumes (p-trend<0.01), polyunsaturated fatty acids (p-trend<0.01) and lower intake of red and processed meats (p-trend=0.03) and sugar-sweetened beverages (p-trend=0.01) were significantly associated with lower odds of physical impairment. For specific foods, higher consumption of lettuce, broccoli, blueberries, peanuts, walnuts and other nuts were associated with lower odds of impairment.

CONCLUSIONS

In this large cohort of older men, better overall diet quality was significantly associated with a lower odds of impairment in physical function. Given the value of physical function to healthy aging and quality of life, this may represent a particularly compelling public health rationale for older men to improve their diet.

Relationship between cardiovascular health metrics and physical performance in community-living people: Results from the Longevity check-up (Lookup) 7+ project

Cardiovascular health metrics (CHMs) may predict disability independent of vascular events. Though, the link between CHMs and physical performance is unclear. This relationship was explored using data from the Longevity check-up (Lookup) 7+ project. Lookup 7+ is an ongoing cross-sectional survey conducted in unconventional settings across Italy. People who are at least 18-year-old and provide written informed consent are eligible. CHMs [i.e., smoking status, healthy diet, body mass index (BMI), blood pressure, blood cholesterol, and diabetes status] are assessed through closed questions and objective measurements. Physical performance is measured via the 5-repetition chair-stand test. Analyses included 7446 participants (55.5 ± 14.9 years; 56% women). Physical performance positively correlated with CHMs scores, such that participants who scored higher (6-7 points) completed the chair-stand test about 2 s faster than those scoring lower (1-2 points). In fully adjusted analysis, better physical performance was more frequently observed in younger, non-smoking, physically active men, with ideal BMI, and no diabetes. Our findings indicate a gradient of better physical function with increasing CHMs scores. Future investigations should establish the longitudinal effect of unhealthy behaviours and cardiovascular risk factors on physical performance and verify whether implementation of large-scale primordial cardiovascular prevention may positively impact physical fitness.

Ideal cardiovascular health and its association with sedentary behaviour and fitness in psychiatric patients. The PsychiActive project

BACKGROUND AND AIMS

Ideal cardiovascular health (CVH) was defined as meeting ideal levels of 4 health behaviours (smoking, body mass index, physical activity, and diet) and 3 biological factors (blood pressure, total cholesterol, and glucose) and is inversely related to cardiovascular disease and mortality. However, the prevalence of ideal CVH in patients with severe mental illness and the possible independent associations of sedentary behaviour and fitness with CVH score are unexplored.

METHODS AND RESULTS

This study included 142 (34 women) outpatients with severe mental illness (primarily schizophrenia, n = 92). CVH was evaluated according to the American Heart Association guidelines. Sedentary behaviour, cardiorespiratory fitness, and muscular strength were measured by an activity-monitor, the 6-min walk test, and handgrip dynamometry. Cardiorespiratory fitness and strength values were combined in a composite fitness score. The prevalence of ideal CVH was: non-smoking (47.9%), body mass index (16.9), physical activity (83.1%), diet (10.4%), blood pressure (40.4%), total cholesterol (62.9%), and plasma glucose (66.7%). Low levels of sedentary behaviour and high cardiorespiratory, strength, and composite fitness score were associated with meeting the ideal threshold in most CVH metrics and having higher global CVH score; however, only cardiorespiratory and composite fitness score remained significantly related to global CVH score independent of sedentary behaviour and multiple confounders.

CONCLUSIONS

Patients with severe mental illness generally have low prevalence of ideal CVH metrics, especially diet and body mass index. Additionally, our findings suggest the need or considering cardiorespiratory fitness, regardless of sedentary behaviour, to promote ideal CVH in this population.

Gender, self-rated health and functional decline among community-dwelling older adults

OBJECTIVE

This paper examines the association between self-rated health (SRH) and functional decline (FD) in older Ghanaian cohorts and investigates whether the effect differs by gender and also modified by marital status.

METHODS

The study used cross-sectional survey data (N = 1200) from an Aging, Health, Psychological Wellbeing and Health-seeking Behavior Study (AHPWHB) study conducted in between August 2016 and January 2017. A four-level gendered-stratified logit modeling estimated the SRH-FD association and the interaction terms.

RESULTS

Overall, 23% of male respondents and 34% of women revealed significant FD (p < 0.001). The fully-adjusted model showed that SRH status was a strong predictor of FD across genders but the effect was most pronounced among men. Compared with excellent/very good SRH, fair and poor SRH (β = 0.160; p < 0.05) and (β = 1.700; p < 0.001) for women and (β = 2.202; p < 0.001) and (β= 2.356; p < 0.001) for men respectively were significantly associated with increased FD. However, good (β = - 1.760; p < 0.001), fair (β = - 2.800; p < 0.001) and poor SRH (β = -2.088; p < 0.001) decreased FD if an older woman was married compared with unmarried women with excellent/very good SRH.

CONCLUSION

The strength of SRH-FDs association largely differed with gender and also moderated by marital status for women. Improving the SRH and marital quality could be protective of functional abilities, independence and quality of life for older people.

PARTICIPANTS

Individuals aged 60 and older who participated in the Swedish National Study on Aging and Care in Kungsholmen and were free of limitations in walking speed (n = 1,441), balance (n = 1,154), or chair stands (n = 1,496) at baseline (2001-04).

MEASUREMENTS

At baseline, data on demographic characteristics, CRFs, other lifestyle factors, C-reactive protein, and cognitive function were collected. CRF burden was measured using the Framingham general cardiovascular risk score (FRS). Limitations in walking speed (<0.8 m/s), balance (<5 seconds), and chair stand (inability to rise 5 times) were determined at 3-, 6-, and 9-year follow-up. Data were analyzed using Cox proportional hazards models stratified according to age (<78, ≥78).

RESULTS

During follow-up, 326 persons developed limitations in walking speed, 303 in balance, and 374 in chair stands. An association between the FRS and walking speed limitation was evident only in adults younger than 78 (for each 1-point increase in FRS: hazard ratio (HR) = 1.09, 95% confidence interval (CI) = 1.02-1.17) after controlling for potential confounders including cognitive function (correspondingly, in adults aged ≥78: HR = 0.98, 95% CI = 0.92-1.03). Also, higher FRS was significantly associated with faster decline in walking speed (P < .001).

CONCLUSION

A higher FRS is associated with greater risk of subsequent development of walking speed limitation in adults younger than 78, independent of cognitive function. Interventions targeting multiple CRFs in younger-old people may help in maintaining mobility function.
