Abstract Background We aimed to examine the effect of physical activity on different cognitive domains among patients with diabetes. Methods We used two waves of data from the Chinese Health and Retirement Longitudinal Study (CHARLS, 2013–2015), a nationally representative dataset of Chinese population aged over 45. Total physical activity scores were calculated based on the International Physical Activity Questionnaire (IPAQ). Executive function and episodic memory were used as measures of cognitive function. We conducted lagged dependent variable models to explore the association between physical activity and cognitive function in full sample as well as two different age groups (45–65, ≥65). Results: 862 diabetic patients were included. We found that diabetic participants who had greater level of physical activity at baseline were associated with better episodic memory function in 2 years (p < 0.05). Moreover, physical activity was significantly associated with less decline in episodic memory in fully adjusted models, and the associations were stronger among patients aged 45–65 years (p < 0.05). No statistically significant association was found between physical activity and executive function in all age groups. Conclusions Physical activity may prevent some of the potential decline in episodic memory in diabetic patients. Clinicians and public health departments should strengthen the promotion of physical activity and develop early screening tools among diabetic participants to prevent the progression of cognitive impairment.

Screen Use

The current study used device-logged screen time records to measure week-to-week within-person associations between stress and smartphone use in undergraduate students (N = 187, Mage = 20.1) during Fall 2020, focusing on differences across types of app used and whether accumulated screen use each week predicted end-of-week mood states. Participants uploaded weekly screenshots from their “Screen Time” settings display and completed surveys measuring stress, mood, and COVID-19 experiences. Results of multilevel models showed no week-to-week change in smartphone hours of use or device pickups. Higher stress levels were not concurrently associated with heavier smartphone use, either overall or by type of app. Heavier smartphone use in a given week did not predict end-of-week mood states, but students who tended to spend more time on their phones in general reported slightly worse moods—a between-person effect potentially reflecting deficits in well-being that are present in students’ offline lives as well. Our findings contribute to a growing scholarly consensus that time spent on smartphones tells us little about young people’s well-being.

Childhood Socioeconomic Status

Objectives:This study examined childhood socioeconomic status (SES) as a predictor of later life cognition and the extent to which midlife SES accounts for associations. Methods: Data came from 5,074 participants in the Wisconsin Longitudinal Study. Measures from adolescence included parents’ educational attainment, father’s occupational status, and household income. Memory and language/executive function were assessed at ages 65 and 72 years. Results: Global childhood SES was a stronger predictor of baseline levels of language/executive function than baseline memory. Associations involving parents’ education were reduced in size and by statistical significance when accounting for participants’ midlife SES, whereas associations involving parental income and occupational status became statistically nonsignificant. We found no associations between childhood SES and change in cognition. Discussion: Findings contribute to growing evidence that socioeconomic differences in childhood have potential consequences for later life cognition, particularly in terms of the disparate levels of cognition with which people enter later life.

The use of digital devices among very young children is quickly spreading, although the effects of screen time on emotional and cognitive functioning are still debated. In a sample of N = 422 children and their mothers, this 4-year longitudinal study aimed to evaluate the hypothesis that the use of digital devices as smartphones and tablets at 4 years of age is related to later dysregulation symptoms and to lower academic achievements both at 6 and 8 years of age. Children’s mothers were asked whether or not their offspring had access to digital devices and what was their average screen time on a typical day. Mothers were also requested to specify whether they used to participate in their children’s activities during screen time and to report their offspring emotional/behavioral functioning. Children’s teachers were administered the Teachers Report Form including the competence part to evaluate academic achievements and possible dysregulation symptoms of their students. The Structural Equation Modeling showed that screen time at 4 years of age, the child was directly, positively and significantly associated with dysregulation and negatively associated with mathematics and literacy grades at 8 years of age of the child. These results could help orientate the guidelines for the use of digital devices by very young children.
