Abstract Recent studies indicate that engaging in more diverse activities is related to higher cognitive functioning. Questions remain, however, regarding whether activity variety within different domains is important. We examined how overall activity variety across domains, as well as variety within cognitive, physical, and social domains are related to cognitive functioning. Data were drawn from Waves 2-3 of Midlife Development in the United States (MIDUS). In cross-sectional analyses (N = 3349), activity variety overall and within each domain were positively related to cognitive functioning regardless of activity frequency. In longitudinal analyses (n = 2054), participants with consistently higher activity variety overall and within the social domain over time (vs. those with consistently low or decreasing activity variety) exhibited better cognitive functioning at W3 after adjusting for cognitive functioning at W2. Findings suggest that engaging in a variety of activities that involve multiple cognitive processes might be beneficial for cognitive health.

The Impact

Abstract Background Older adults are particularly vulnerable to the adverse health effects of extreme temperature-related events. A growing body of literature highlights the importance of the natural environment, including air pollution and sunlight, on cognitive health. However, the relationship between exposure to outdoor temperatures and cognitive functioning, and whether there exists any differences across climate region, remains largely unexplored. We address this gap by examining the temperature-cognition association, and whether there exists any variation across climate regions in a national cohort of aging adults. Methods In this cross-sectional study, we obtained data on temperature exposure based on geocoded residential location of participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. For each participant, this information was linked to their cognitive scores from Word List Learning and Recall tests to assess cognitive functioning. We used distributed lag non-linear models (dlnm) to model temperature effects over 2 days. Multivariable linear regression was used to compute temperature-cognitive functioning associations, adjusted for important covariates. Region-specific (“Dry”, “Mediterranean/oceanic”, “Tropical” and “Continental”) associations were examined by including an interaction term between climate region and temperature. Results Amongst 20,687 individuals (mean age = 67.8; standard deviation = 9.2), exposure to region-specific extreme cold temperatures in the “dry” region (e.g., Arizona) over 2 days was associated with lower cognitive scores (Mean Difference [MD]: -0.76, 95% Confidence Interval [CI]: − 1.45, − 0.07). Associations remained significant for cumulative effects of temperature over 2 days. Extremely cold exposure in the “Mediterranean/oceanic” region (e.g., California) over 2 days was also associated with significantly lower cognitive performance (MD: -0.25, 95% CI: − 0.47, − 0.04). No significant associations were observed for exposure to hot temperatures. Cognitive performance was slightly higher in late summer and fall compared to early summer. Conclusion We noted adverse cognitive associations with cold temperatures in traditionally warmer regions of the country and improved cognition in summer and early fall seasons. While we did not observe very large significant associations, this study deepens understanding of the impact of climate change on the cognitive health of aging adults and can inform clinical care and public health preparedness plans.

Abstract Objective: To examine whether the density of neighbourhood restaurants affected the frequency of eating restaurant meals and subsequently affected diet quality. Design: Cross-sectional and longitudinal designs. Structural equation models assessed the indirect relationship between restaurant density (≤3 miles (4.8 km) of participant addresses) and dietary quality (Healthy Eating Index 2010 (HEI)) via the frequency of eating restaurant meals, after adjustment for sociodemographics, select health conditions, region, residence duration and area-level income. Setting: Urbanised areas in multiple regions of the USA, years 2000–2002 and 2010–2012. Participants: Participants aged 45–84 years were followed for 10 years (n 3567). Results: Median HEI (out of 100) was 59 at baseline and 62 at follow-up. Cross-sectional analysis found residing in areas with a high density of restaurants (highest ranked quartile) was associated with 52% higher odds of frequently eating restaurant meals (≥3 times/week, odds ratio [OR]:1.52, 95% confidence interval [CI] 1.18-1.98) and 3% higher odds of having lower dietary quality (HEI lowest quartile<54, OR:1.03,CI:1.01-1.06); associations were not sustained in longitudinal analyses. Cross-sectional analysis found 34% higher odds of having lower dietary quality for those who frequently ate at restaurants (OR:1.34,CI:1.12-1.61); and more restaurant meals (over time increase ≥1 times/week) was associated with higher odds of having worse dietary quality at follow-up (OR:1.21,CI:1.00-1.46). Conclusions: Restaurant density was associated with frequently eating out in cross-sectional and longitudinal analyses but was associated with the lower dietary quality only in cross-sectional analyses. Frequent restaurant meals were negatively related to dietary quality. Interventions that encourage less frequent eating out may improve population dietary quality.

Abstract Background Students’ attitudinal beliefs related to how they see themselves in STEM have been a focal point of recent research, given their well-documented links to retention and persistence. These beliefs are most often assessed cross-sectionally, and as such, we lack a thorough understanding of how they may fluctuate over time. Using matched survey responses from undergraduate engineering students (n = 278), we evaluate if, and to what extent, students’ engineering attitudinal beliefs (attainment value, utility value, self-efficacy, interest, and identity) change over a 1-year period. Further, we examine whether there are differences based on gender and student division, and then compare results between cross-sectional and longitudinal analyses to illustrate weaknesses in our current understanding of these constructs. Results Our study revealed inconsistencies between cross-sectional and longitudinal analyses of the same dataset. Cross-sectional analyses indicated a significant difference by student division for engineering utility value and engineering interest, but no significant differences by gender for any variable. However, longitudinal analyses revealed statistically significant decreases in engineering utility value, engineering self-efficacy, and engineering interest for lower division students and significant decreases in engineering attainment value for upper division students over a one-year period. Further, longitudinal analyses revealed a gender gap in engineering self-efficacy for upper division students, where men reported higher means than women. Conclusions Our analyses make several contributions. First, we explore attitudinal differences by student division not previously documented. Second, by comparing across methodologies, we illustrate that different conclusions can be drawn from the same data. Since the literature around these variables is largely cross-sectional, our understanding of students’ engineering attitudes is limited. Our longitudinal analyses show variation in engineering attitudinal beliefs that are obscured when data is only examined cross-sectionally. These analyses revealed an overall downward trend within students for all beliefs that changed significantly—losses which may foreshadow attrition out of engineering. These findings provide an opportunity to introduce targeted interventions to build engineering utility value, engineering self-efficacy, and engineering interest for student groups whose means were lower than average.

Introduction: Stroke incidence is reportedly increasing in younger adults. While increasing vascular risk factor prevalence has been suggested as a cause, the reasons for rising stroke incidence in the young are not clear. We explored several alternate explanations: trends in neurologically-focused emergency department (ED) visits, differential diagnostic classification of stroke and TIA over time, and changes in the use of advanced imaging in young and older adults. Methods: We performed a retrospective, serial, cross-sectional study on a nationally representative sample of all ED visits in the United States to quantify changes in patterns of neurologically-focused ED visits, stroke and TIA diagnoses, and rates of MRI utilization for young (18 – 44 years) and older (65+ years) adults over a 17-year period (1995 – 2000; 2005 – 2015) using National Hospital Ambulatory Medical Care Survey (NHAMCS) data. Results: In young adults, 0.4% (95% CI 0.3% – 0.5%) of neurologically-focused ED visits resulted in a primary diagnosis of stroke vs. 6.8% (95% CI 6.2% – 7.5%) for older adults. In both populations, the incidence of neurologically-focused ED visits has increased over time (+111/100,000 population/year, 95% CI +94 – +130 in the young vs. +70/100,000 population/year, 95% CI +34 – +108 in older adults). There was no evidence of differential classification of TIA to stroke over time (OR 1.001 per year, 95% CI 0.926 – 1.083 in the young; OR 1.003 per year, 95% CI 0.982 – 1.026 in older adults) and no evidence of disproportionate rise in MRI utilization for neurologically-focused ED visits in the young (OR 1.057 per year, 95% CI 1.028 – 1.086 in the young; OR 1.095 per year, 95% CI 1.066 – 1.125 in older adults). Conclusions: If the specificity of stroke diagnosis amongst ED visits is similar amongst young and older populations, then the combination of data observed here, including (1) a lower prior probability of stroke diagnoses in the young and (2) an increasing trend in neurologically-focused ED visits in both age groups, suggests that false positive diagnoses will increase over time, with a faster rise in the young compared to older adults. These data suggest a potential explanation that may contribute to higher stroke incidence in the young and merits further scrutiny.

Barriers And Motivators

Introduction. Physical activity (PA), particularly low-impact activities like bicycling, can improve health in older adults. However, bicycling rates are lower in the Midwest than other regions in the United States. Therefore, it is important to identify unique social, personal, and environmental factors that inhibit or promote bicycling, and how these are associated with PA. The influences of these factors were explored using the social ecological model. Method. A cross-sectional online survey was developed using previously validated local and national bicycling questionnaires, then distributed to Midwestern bicyclists 50 years and older. Exploratory factor analysis was conducted to understand the influences of social, personal, and environmental barriers and promoters on bicycling patterns. All models were conducted separately by gender, and accounted for age, race, education, marital status, income, and employment. Results. Social promoters (B = 0.386, p = .002), such as having friends/family that bicycle were associated with greater PA. Personal promoters (B = −0.311, p = .006) such as needing to lose weight were associated with reduced PA. Environmental factors had no associations with PA. However, individual environmental components, such as number of vehicles on the roads, were significantly associated with PA for both males and females. Females reported more barriers than males. The overall model accounted for 16.1% of the total variance in PA levels. Conclusion. Interventions to promote PA via bicycling in older adults should focus on social factors, while also reducing personal-level factors for males. Interventions for females could focus on reducing specific personal, social, and environmental barriers.

Abstract In some Scandinavian countries, the United Kingdom and the United States, there is evidence of a dramatic decline in adolescent emotional wellbeing, particularly among girls. It is not clear to what extent this decline can be generalised to other high-income countries. This study examines trends over time (2005-2009-2013-2017) in adolescent wellbeing in the Netherlands, a country where young people have consistently reported one of the highest levels of wellbeing across Europe. It also assesses parallel changes over time in perceived schoolwork pressure, parent-adolescent communication, and bullying victimization. Data were derived from four waves of the nationally representative, cross-sectional Dutch Health Behaviour in School-aged Children study (N = 21,901; 49% girls; Mage = 13.78, SD = 1.25). Trends in emotional wellbeing (i.e., emotional symptoms, psychosomatic complaints, life satisfaction) were assessed by means of multiple regression analyses with survey year as a predictor, controlling for background variables. Emotional wellbeing slightly declined among adolescent boys and girls between 2009 and 2013. A substantial increase in perceived schoolwork pressure was associated with this decline in emotional wellbeing. Improved parent-adolescent communication and a decline in bullying victimization may explain why emotional wellbeing remained stable between 2013 and 2017, in spite of a further increase in schoolwork pressure. Associations between emotional wellbeing on the one hand and perceived schoolwork pressure, parent-adolescent communication, and bullying victimization on the other were stronger for girls than for boys. Overall, although increasing schoolwork pressure may be one of the drivers of declining emotional wellbeing in adolescents, in the Netherlands this negative trend was buffered by increasing support by parents and peers. Cross-national research into this topic is warranted to examine the extent to which these findings can be generalised to other high-income countries.

The analysis of markets, courts, and civil litigation on the northeastern frontier of the United States provides a valuable opportunity to assess the evolution of institutions during economic development. The data set pools longitudinal and cross-sectional observations on 30,000 lawsuits filed in Maine during the critical period between 1700 and 1860. The earliest legal institutions moderated both social and economic norms, but courts quickly began to specialize in commercial issues. The residence of debtors and creditors and changes in spatial characteristics over time yield insights into the nature and extent of capital markets and impersonal exchange. The distribution and disposition of property and debt cases indicate that early markets were well developed and orderly; the evidence of “social tension” between debtors and creditors was minimal. The results do not support the standard claim of a transition from interactions based on community norms to impersonal market exchange late in the eighteenth century.

Abstract Objectives Prior studies on caregivers have focused mainly on the diet quality of their recipients, especially children. We investigated both cross-sectional and longitudinal associations of caregiver status and diet quality in older adults (mean 53.0 ± 9.0 years). Methods We studied participants in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study (57.7% women, 62% African American) between wave 3 (2009–2013) and wave 4 (2013–2018). Caregiving was assessed at both waves, starting at wave 3. Healthy Eating Index-2010 (HEI2010) score, a measure of diet quality, was assessed from two 24-hour recalls at each wave on both occasions (mean 4.1 years follow-up). Baseline caregiving (at wave 3) was examined in relation to change in HEI between waves 3 and 4. Multivariable linear regression was performed for cross-sectional analysis; mixed-effects regression was performed for longitudinal analyses. Results are expressed as β-coefficients ± standard error of means (β±SE). Results After adjusting for age, sex, race and poverty status, more time spent taking care of grandchildren (N = 2033) was associated with poor diet quality (–1.51 ± 0.55, P = 0.006) in cross-sectional analysis (wave 4 caregiving and wave 4 HEI). However, in a separate cross-sectional analysis (wave 4 only) on dual (caring for both grandchildren and an elderly person) vs. single caregivers (either grandchildren or elderly) (N = 73; 24 men & 49 women) we found no difference in diet quality. The longitudinal analyses (N = 1848) demonstrated that diet quality did not change with caregiving over time for either grandchildren (P = 0.16) or others (not children & grandchildren) (P = 0.88). Overall, women tended to have better quality diet (P &lt; 0.001) than men. Conclusions Among relatively older caregivers, cross-sectional analyses revealed an inverse effect of caregiving with diet quality. Longitudinal research is needed to evaluate the temporal associations of dual caregiving with subsequent diet quality changes over time.

AbstractWe study the social discount rate, taking into account inequality within generations, that is, across countries or individuals. We show that if inequality decreases over time, the social discount rate should be lower than the one obtained by the standard Ramsey rule under certain but reasonable conditions. Applied to the global discount rate and due to the projected convergence across countries, this implies that the inequality adjusted discount rate should be about twice as high as the standard Ramsey rule predicts. For individual countries on the other hand, where inequality tends to increase over time, the effect goes in the other direction. For the United States for instance, this inequality effect leads to a reduction of the social discount rate by about 0.5 to 1 percentage points. We also present an analytical formula for the social discount rate allowing us to disentangle inequality, risk, and intertemporal fluctuation aversion.

Background: The COVID-19 pandemic created significant disruptions for college students, impacting health and physical activity (PA). Changes to the PA environment presented many challenges for students.Purpose: To examine the influence of the physical and social environment on PA participation for college students during the onset of COVID-19 restrictions.Methods: This cross-sectional, mixed methods survey used an online questionnaire during the onset of COVID-19 restrictions with a volunteer sample of college students at a large university in the United States. Participants self-reported their demographics, PA level and environment for PA, and responded to an open-ended question about their PA participation during the pandemic. Correlations and independent samples t-tests examined relationships between PA and the environment. Qualitative data were scanned to identify overarching themes.Results: Participants (n = 395) were predominantly Non-Hispanic White and female. The neighborhood environment and access to PA equipment were associated with PA for both men and women. Major qualitative themes highlighted the role of the physical environment and PA. Participating in PA with friends and family was positively associated with PA for both men and women as well.Conclusions: This study provides insight on the importance of the social and built environment for encouraging and supporting PA among college students during the COVID-19 pandemic which may provide insight for distance education as higher education evolves.
