Longitudinal Associations Between Contact Frequency with Friends and with Family, Activity Engagement, and Cognitive Functioning.

ABSTRACT: OBJECTIVES:Social engagement may be an important protective resource for cognitive aging. Some evidence suggests that time spent with friends may be more beneficial for cognition than time spent with family. Because maintaining friendships has been demonstrated to require more active maintenance and engagement in shared activities, activity engagement may be one underlying pathway that explains the distinct associations between contact frequency with friends versus family and cognition. METHODS:Using two waves of data from the national survey of Midlife in the United States (n = 3707, Mage = 55.80, 51% female at baseline), we examined longitudinal associations between contact frequency with friends and family, activity engagement (cognitive and physical activities), and cognition (episodic memory and executive functioning) to determine whether activity engagement mediates the relationship between contact frequency and cognition. RESULTS:The longitudinal mediation model revealed that more frequent contact with friends, but not family, was associated with greater concurrent engagement in physical and cognitive activities, which were both associated with better episodic memory and executive functioning. CONCLUSION:These findings suggest that time spent with friends may promote both cognitively and physically stimulating activities that could help to preserve not only these social relationships but also cognitive functioning.

Project description:ImportanceWorsening vision and declining cognitive functioning are common conditions among elderly individuals. Understanding the association between them could be beneficial in mitigating age-related cognitive changes.ObjectiveTo evaluate the longitudinal associations between visual impairment and cognitive function over time in a population-based study of older US adults.Design, setting, and participantsProspective longitudinal population-based study of older adults in the greater Salisbury area in Maryland. Overall, 2520 community-residing adults aged 65 to 84 years were assessed at baseline between September 1993 and August 1995 (round 1) and 2 (round 2), 6 (round 3), and 8 (round 4) years later.Main outcomes and measuresVisual acuity (VA) was measured using Early Treatment Diabetic Retinopathy Study charts, and cognitive status was assessed using the Mini-Mental State Examination (MMSE).ResultsOf 2520 individuals, the mean (SD) age was 73.5 (5.1) years, 1458 (58%) were women, and 666 (26%) were black. There were 2240 (89%), 1504 (61%), and 1250 (50%) participants in the second, third, and fourth round of study, respectively, with more than half of the loss being due to death. Both VA and MMSE score worsened over time. The mean biannual decline of VA was 0.022 logMAR (approximately 1 line during 8 years; 95% CI, 0.018-0.026), and the mean biannual worsening of MMSE score was -0.59 (95% CI, -0.64 to -0.54; both P < .001). Worse baseline VA was associated with worse baseline MMSE score (r = -0.226; 95% CI, -0.291 to -0.16; P < .001). The rate of worsening VA was associated with the rate of declining MMSE score (r = -0.139; 95% CI, -0.261 to -0.017; P = .03). Cross-lagged models indicated VA in the previous round was associated with MMSE score in the subsequent round (β = -0.995, P < .001), and MMSE score in the previous round was associated with VA in the following round (β = -0.003, P < .001). However, the standardized effect size of VA on MMSE score (β = -0.074; SE, 0.015; P < .001) is larger relative to the reverse effect (β = -0.038; SE, 0.013; P < .001), demonstrating VA is likely the driving force in these dynamic associations.Conclusions and relevanceIn a population-based sample of older US adults, visual impairment measured at distance is associated with declining cognitive function both cross-sectionally and longitudinally over time with worsening vision having a stronger association with declining cognition than the reverse. Worsening vision in older adults may be adversely associated with future cognitive functioning. Maintaining good vision may be an important interventional strategy for mitigating age-related cognitive declines.

Project description:OBJECTIVES:To describe aerobic physical activity among middle-aged and older adults by their self-reported cognitive decline and their receipt of informal care for declines in cognitive functioning and most common type of physical activity. DESIGN:Cross-sectional study using data from the 2011 Behavioral Risk Factor Surveillance System. SETTING:Landline and cellular telephone survey. PARTICIPANTS:93,082 respondents aged 45 years and older from 21 US states in 2011. MEASUREMENTS:Subjective cognitive decline (SCD) was defined as experiencing confusion or memory loss that was happening more often or getting worse during the past 12 months. Regular care was defined as always, usually, or sometimes receiving care from family or friends because of SCD. Using the 2008 Physical Activity Guidelines for Americans, respondents were classified as being inactive, insufficiently active, or sufficiently active based on their reported aerobic exercise. We calculated weighted proportions and used chi-square tests for differences across categories by SCD status and receipt of care. We estimated the prevalence ratio (PR) for being inactive, insufficiently active, and sufficiently active using separate log-binomial regression models, adjusting for covariates. RESULTS:12.3% of respondents reported SCD and 23.1% of those with SCD received regular care. 29.6% (95%CI: 28.9-30.4) of respondents without SCD were inactive compared to 37.1% (95%CI: 34.7-39.5) of those with SCD who did not receive regular care and 50.2% (95%CI: 45.2-55.1) of those with SCD who received regular care. 52.4% (95%CI: 51.6-53.2) of respondents without SCD were sufficiently active compared to 46.4% (95%CI: 43.8-49.0) of respondents with SCD and received no regular care and 30.6% (95%CI: 26.1-35.6) of respondents with SCD who received regular care. After adjusting for demographic and health status differences, people receiving regular care for SCD had a significantly lower prevalence of meeting aerobic guidelines compared to people without SCD (PR=0.80, 95%CI: 0.69-0.93, p=0.005). The most prevalent physical activity was walking for adults aged ? 45 years old (41-52%) regardless of SCD status or receipt of care. CONCLUSION:Overall, the prevalence of inactivity was high, especially among people with SCD. These findings suggest a need to increase activity among middle-aged and older adults, particularly those with SCD who receive care. Examining ways to increase walking, potentially by involving informal caregivers, could be a promising way for people with SCD to reduce inactivity and gain the health benefits associated with meeting physical activity guidelines.

Project description:BACKGROUND:As the population ages, cognitive decline and dementia have become major health concerns in the UK. Loneliness has been linked to cognitive decline, but the reverse causality of this association remains unclear. This study aims to examine whether there is a bidirectional relationship between loneliness and cognitive function in older English adults (age 50?years and over) over a 10-year follow-up. METHODS:Data came from a nationally representative sample of 5885 participants in the English Longitudinal Study of Ageing (ELSA), free of stroke or dementia and followed every 2 years up to wave 7 (2014-15). At each wave, cognitive function was measured with word recall and verbal fluency tests, and loneliness was measured with the abridged version of the revised UCLA Loneliness Scale. Bivariate dual change score models were used to assess the multivariate associations between loneliness and cognitive function, used interchangeably as exposures and outcomes. RESULTS:Greater loneliness at baseline was associated with poorer memory [? intercept = -0.03, standard error (SE) = 0.01, P? = ?0.016] and verbal fluency (? intercept = -0.01, SE? = ?001, P = ?0.027) at baseline, and with a stronger linear rate of decline in both memory (? linear slope = -0.07, SE? = ?001, P ???0.001) and verbal fluency (? linear slope = -0.09, SE? = ?0.03, P = ?0.003) over a 10-year follow-up period, although the performance on verbal fluency did not change substantially on average over this period. We also found that higher baseline memory, but not verbal fluency, predicted a slower change in loneliness (? linear slope = -0.01, SE? = ?001, P = ?0.004) and that a linear decline in memory was associated with an acceleration in loneliness (? quadratic slope = -0.02, SE? = ?001, P ???0.001) during follow-up. CONCLUSIONS:Higher loneliness is associated with poorer cognitive function at baseline and contributes to a worsening in memory and verbal fluency over a decade. These factors seem, however, to be partially intertwined, since baseline memory and its rate of decline also contribute to an increase in loneliness over time.

Project description:RationaleLeisure activities have wide-ranging benefits for physical and mental health. However, previous studies have often focused on "leisure" as a homogeneous group of activities. This study was therefore designed to take a prospective and comparative approach exploring different types of leisure activities, as well as investigating whether frequency of engagement is associated with strength of benefits.MethodData from the 1970 British Cohort Study Waves 9 (age 42) and 10 (age 46) were analysed (N = 5,639). Eight domains derived from the SF-36 health survey questionnaire were used to measure health functioning (general health, vitality, bodily pain, social functioning, physical functioning, mental health, role limitations due to emotional, and role limitations due to physical problems). Leisure activities included physical activity, culture engagement, arts participation, volunteering or community engagement, and literature activities. Both ordinary least squares and logistic regressions were applied.ResultsPhysical activity was associated with greater levels of physical functioning, general health, and vitality at higher frequencies, while cultural engagement was associated with social functioning and physical functioning when engaged in several times a year. Arts participation and literature activities had a general negative association with health functioning. Engagements in volunteering/community groups showed varying associations with health functioning (both positive and negative) depending on the levels of engagements.ConclusionThis research suggests that the types of leisure activities and levels of engagement can have differential associations with health amongst middle-aged adults. This may be helpful for public health initiatives and programmes such as social prescribing schemes when formulating programmes, especially regarding 'dosage' of engagement. Further, the overall benefits of high engagement frequency suggest that increasing leisure engagement could play an important role in supporting improving health and wellbeing at a population level.
