It isn't just Mom: Gendered provision of family and home responsibilities among emerging adults during COVID-19.

Media and research reports have highlighted the disproportionate burden of home and family responsibilities shouldered by women and mothers due to COVID-19-related school/childcare shutdowns. This cross-sectional study extends this line of inquiry to emerging adults. Our study of 329 diverse emerging adults suggests that young women took on more home/family responsibilities than young men amidst the pandemic, and that these duties were associated with symptoms of depression. However, results also indicate that emerging adults who reported greater home/family responsibilities amidst the pandemic also experienced more quality family time, suggesting that pandemic-related challenges may have also been accompanied by opportunities for family connection. Contrary to previous research that has shown home/family responsibilities to be concentrated by SES and race/ethnicity, we found that participants uniformly endorsed COVID-19-related impacts on home/family responsibilities across these demographic distinctions. This could reflect the ubiquity of COVID-19's impact; across race/ethnicity and class-but differentially by gender-young adults faced significant challenges in taking on new home/family roles.

Digital location tracking in the parent/caregiver-college student dyad.

INTRODUCTION: As college students navigate new developmental milestones, many families rely on digital technology to stay connected and aid in the transition to adulthood. Digital location tracking apps allow for parental monitoring in new ways that may have implications for youth development. Although recent research has begun to examine prevalence and motivations for digital location tracking in adolescence, we know little about how and why families continue to track into the transition to college, and how this may relate to perceptions of helicopter and autonomy supportive parenting. METHODS: In a cross-sectional study of 706 community college and 4-year university students in the Southeastern United States, we describe prevalence and sociodemographic differences in parent/caregiver digital location tracking of their college student children, and how this may be associated with perceptions of helicopter parenting and parent/caregiver autonomy support. RESULTS: Findings suggest that digital location tracking is a fairly common practice among college students, with nearly half of the sample endorsing currently or previously being digitally location tracked by their parent/caregiver. Younger, White, and higher socioeconomic status students were more likely to be tracked. Those students who were currently being digitally location tracked tended to perceive their primary parent/caregiver as engaging in more helicopter parenting and as less supportive of their autonomy. CONCLUSIONS: This brief report provides preliminary insight into parent/caregiver digital location tracking of their college student children. It is our hope that future research will further examine how digital location tracking may be helping or hindering attainment of developmental milestones in the digital age.

Can Stereotype Threat and Lift Visual Messages Affect Subsequent Physical Activity? Evidence from a Controlled Experiment Using Accelerometers.

This study investigated how visual messages conveying stereotype threat or lift influenced physical activity performance. Participants (N = 380) were exposed to a stereotype threat, lift, or control condition image and then engaged in a running task. Accelerometers recorded forward-backward movement, upward-downward movement, and sideways balance. Stereotype threat exposure increased state anxiety relative to the control condition. In addition, forward-backward movement was linked to state anxiety and participants' sex. Moreover, women exposed to stereotype threat who experienced increased state anxiety showed reduced forward-backward movement. Men exposed to stereotype lift displayed higher forward-backward movement. Additionally, stereotype threat visual message exposure increased sideways balance activity for women but not for men. Upward-downward movement was unaffected by stereotype threat or lift. We discuss theoretical and practical implications of how exposure to visual stereotypes can influence physical activity performance.

[Frequency of diabetic retinopathy and associated factors in Puerto Montt, Chile]. / Estudio de prevalencia de retinopatía diabética en pacientes diabéticos tipo 2 de la comuna de Puerto Montt y sus factores asociados.

BACKGROUND: Diabetic retinopathy (DR) is an important cause of decreased visual acuity, whose prevalence has increased between 1990 and 2020. In Chile the prevalence of diabetic retinopathy was estimated at 24.8%. AIM: To assess the prevalence of DR in a southern Chilean city. MATERIAL AND METHODS: From a database of diabetic patients attending primary health care centers at Puerto Montt, Chile, 196 patients with DR and 392 patients without DR, matched by age and presence of chronic complications, were chosen for this case-control study. RESULTS: The prevalence of DR in the database of diabetic patients was 33.3%. glycated hemoglobin, the frequency insulin use, systolic blood pressure, HDL cholesterol, microalbuminuria, and proteinuria were significantly worse in cases. A multivariate analysis showed that retinopathy is much more likely to occur when the variables insulin use, neuropathy, and microalbuminuria concur. CONCLUSIONS: DR was associated with worse metabolic parameters and the presence of neuropathy in this case control study.

Dyadic parent-college student digital interaction styles.

Parents and their emerging adult children are highly connected via mobile phones in the digital age. This digital connection has potential implications for the development of autonomy and sustained parent-child relatedness across the course of emerging adulthood. The present study uses the qualitatively coded content of nearly 30,000 U.S. parent-college student text messages, exchanged by 238 college students and their mothers and fathers over the course of 2 weeks, to identify distinct dyadic parent-emerging adult digital interaction styles across dimensions of responsiveness and monitoring. Results reveal that digital interaction styles are largely consistent across age, gender, and parent education as well as reflective (i.e., texting patterns of parents and emerging adults mirror one another), with little evidence of overparenting profiles. Results also show that those college students who are reciprocally disengaged in text messaging with their parents perceive their parents as less digitally supportive. However, no styles were associated with perceived parental pressure to digitally engage. Findings suggest that the mobile phone is likely a valuable tool to maintain connection with few risks for undermining the privacy and autonomy of emerging adults.

Nutritional education knowledge of teachers and nutritionists in four European countries / Conocimientos sobre educación nutricional de profesores y nutricionistas de cuatro países europeos

Objective: the aim of this study was to examine the perception of professionals from four European countries in charge of teaching Nutrition Education (NE) to children in primary schools or hospitals. Methods: this was achieved through an exploratory study that initiated with two focus groups, one with 5 elementary school teachers and another with 14 nutritionists. From the results of it an online survey was designed and distributed internationally to elementary schools and professional clinics in Spain, Italy, Norway, and Austria. The participants were 75 elementary school teachers and 98 nutritionists. It was measured the level of knowledge of teachers and nutritionists to teach NE, and the level of nutritional knowledge of the children in their respective country. Descriptive statistics were conducted, one-factor ANOVAs to analyze the effect of nationality, and when a significant interaction was found, a post-hoc analysis using Bonferroni adjustment was applied. Results: the results indicated that forty-one percent of the participants considered they have “adequate” theoretical knowledge to teach NE. Only 27 % considered they had “adequate” pedagogical training. A significant effect was found: F(3,168) = 17.37, p < 0.001, η2p = 0.24. Regarding the levels of NE knowledge of children, from lowest to highest, there were Spain, Italy, Austria, and Norway. Also, it was observed that professionals and children from Spain and Italy were more affected with less knowledge and training regarding NE. Conclusions: these results could help governments and educational organizations of the affected countries to take decisions to tackle this problematic. (AU)

Urinary Angiotensinogen in Patients With Type 1 Diabetes With Microalbuminuria: Gender Differences and Effect of Intensive Insulin Therapy.

Introduction: Angiotensinogen (AOG) is the precursor of peptides of the renin angiotensin system (RAS). Because insulin up-regulates transcriptional factors that normally repress kidney AOG synthesis, we evaluated urinary AOG (uAOG) in patients with type 1 diabetes (T1D) and microalbuminuria who are receiving either intensive or conventional insulin therapy. Methods: Urine samples from participants of the Diabetes Control and Complications Trial (DCCT) were used for the following: (i) uAOG/creatinine measurements in 103 patients with microalbuminuria and 103 patients with normoalbuminuria, matched for age, gender, disease duration, and allocation to insulin therapy; and (ii) uAOG/creatinine measurements from patients with microalbuminuria allocated to intensive insulin therapy (n = 58) or conventional insulin therapy (n = 41) after 3 years on each modality. Results: uAOG was higher in patients who started with microalbuminuria than in those with normoalbuminuria (6.65 vs. 4.0 ng/mg creatinine, P < 0.01). uAOG was higher in females than in males with microalbuminuria (11.7 vs. 5.4 ng/mg creatinine, P = 0.015). uAOG was lower in patients with microalbuminuria allocated to intensive insulin therapy than in conventional insulin therapy (3.98 vs. 7.42 ng/mg creatinine, P < 0.01). These differences in uAOG were observed though albumin excretion rate (AER) was not significantly different. Conclusion: In patients with T1D and microalbuminuria, uAOG is increased and varies with gender and the type of insulin therapy independently of AER. This suggests that AOG production is increased in females and it is decreased by intensive insulin therapy. The reduction in uAOG with intensive insulin therapy, by kidney RAS downregulation, may contribute to the known renoprotective action associated with intensive insulin and improved glycemic control.

Caracterización de patrones alimentarios durante la pandemia por COVID 19 en Chile / Characterization of food patterns during the COVID 19 pandemic in Chile

Technologizing Bronfenbrenner: Neo-ecological Theory.

We propose an adaptation of Urie Bronfenbrenner's bioecological theory, neo-ecological theory. As bioecological theory was developed in the 20th century, it requires significant modifications to reflect some of the most ubiquitous contexts in which adolescents learn, play, and grow-the technological and virtual ones. Although several scholars have developed laudable theories related to youth development in virtual contexts, the field lacks an overarching theory to address the intersection of development and technology. In developing neo-ecological theory, we hold true to the tenets of bioecological theory, but suggest key modifications to reflect our technologized world. We delineate a key alteration to the microsystem, namely the existence of two types of microsystems-physical and virtual. In addition, we emphasize the importance of macrosystemic influences (i.e., the influences of culture and within-society subcultural variation) in understanding development in the digital age. The implications of these modifications cascade across the Process-Person-Context-Time (PPCT) model; proximal processes, person characteristics, context, and time are all reexamined. In the digital age, virtual microsystems are central contexts in which youth engage in proximal processes. As such, we believe that all scholars of development, regardless of their specific research interests, should consider the ways digital contexts influence their outcomes of interest. Without it, practitioners, policy makers, parents, and technologists will be in the dark about how best to support adolescents.

Can Avatar Appearance Influence Physical Activity? User-Avatar Similarity and Proteus Effects on Cardiac Frequency and Step Counts.

This study combined user-avatar similarity and Proteus effect predictions to incentivize physical activity. 305 participants ran while wearing accelerometers and a heart rate monitor. They were randomly assigned to onscreen motion-capturing avatars displaying either participant or stranger faces dressed in sports or formal clothes. Participants assigned to avatars displaying their own face showed increased cardiac frequency compared with those exposed to avatars with a stranger's face. Relative to the remaining conditions, participants assigned to avatars with their own face also wearing sports clothes showed increased cardiac frequency but participants assigned to avatars with a stranger's face wearing formal clothes showed decreased cardiac frequency. The results imply that user-avatar similarity and the Proteus effect can be harnessed to influence physical activity.

Adolescent Motivation Toward Physical Exercise: The Role of Sex, Age, Enjoyment, and Anxiety.

Physical exercise declines during adolescence due to several factors, such as lack of intrinsic motivation or enjoyment, high physical exercise anxiety, and so on. The objectives of this study were to validate the psychometric structure of the Behavioral Regulation in Exercise Questionnaire-2 to confirm the existence of five levels of motivation toward physical exercise in adolescent population, as well as to analyze the differences in motivation according to sex and age, and the role of age and sex in the relationship between motivation and enjoyment. To do so, 666 students between 10 and 16 years old completed the Behavioral Regulation in Exercise Questionnaire-2 and questionnaires related to enjoyment and physical exercise anxiety. The confirmatory factor analysis of the Behavioral Regulation in Exercise Questionnaire-2 showed a five-factor structure. However, a more parsimonious four-factor structure with a single intrinsic-identified regulation emerged through an exploratory factor analysis. The more self-determined types of motivation were positively associated with enjoyment and negatively with anxiety, the type of physical exercise motivation fluctuated depending on age and sex, and the age moderated the relationship between motivation and enjoyment. This study highlights the importance of fostering specific types of motivation to improve the physical exercise and the relevance of age and sex when developing interventions.

Efficacy and acceptability of a web platform to teach nutrition education to children / Eficacia y aceptabilidad de una plataforma web para enseñar educación nutricional a niños

INTRODUCTION: Nutrition Education (NE) has been identified as a key factor to prevent children obesity. Teachers and dietitians are the professionals in charge of transmitting this knowledge to children; however, it has been identified that they do not possess either proper training, or the proper tools to perform this activity. OBJECTIVES: to evaluate the acceptability and usability of a NE Internet platform and its two "Serious Games" (SGs) among a sample of elementary school teachers, dietitians, and education students. In addition, to evaluate the efficacy of this platform to teach NE in a sample of children aged 9 to 12 years. METHODS: a total of 66 NE professionals and 135 children participated. Usability and acceptability questionnaires of the platform and an instrument to measure the acceptability, immersion, and playability of the SGs were administered to the professionals. The children fulfilled a questionnaire on nutritional knowledge. Descriptive statistics analyzed the main responses of the professionals involved, and an ANOVA compared the differences observed. For the children's data a t-test of repeated samples and a repeated-measures ANOVA were performed. RESULTS: dietitians and education students responded with a favorable opinion about the platform; however, the scores given by all professionals to the SGs ranged from low to moderate. Children increased their nutritional knowledge from pre to post evaluation (p < 0.001). This increase was observed in 10-year-old children and in children with 11 to 12 years of age, but not in 9-year-olds. CONCLUSIONS: this platform proved to be an effective tool to increase children's nutritional knowledge. Professionals expressed a medium level in terms of acceptability and usability for this platform, but also effectiveness in providing NE to children

Manipulating Self-Avatar Body Dimensions in Virtual Worlds to Complement an Internet-Delivered Intervention to Increase Physical Activity in Overweight Women.

Virtual reality has been found to be a useful tool for positively influencing relevant psychological variables in order to increase physical activity (PA), especially in the overweight population. This study investigates the use of avatars and their physical variations to extend the effectiveness of existing interventions to promote PA. The main objective is to analyze the influence of the avatars' body dimensions on the efficacy of an Internet intervention to increase PA levels and improve other relevant variables (motivation toward PA, enjoyment, anxiety, self-efficacy, and PA goals). A total of 42 overweight women received a brief online intervention, and they were randomly assigned to one of three conditions: the "Ideal avatar" (IAC: participants are represented by avatars with ideal body dimensions); the "Real avatar" (RAC: participants are represented by avatars with participants' current body dimensions); and the "Non avatar" (NAC: participants are not represented by avatars). Results showed that the online intervention was effective in increasing PA practice and self-efficacy expectations. However, manipulating the body dimensions of avatars did not improve this intervention, although ideal avatars helped to reduce the anxiety experienced during PA in this population.

Unexpected Reduced Biventricular Ejection Fraction in a Healthy Young Male.

We describe the case of a 31-year-old male who came to the emergency department complaining of marked bilateral lower extremities edema, dyspnea, fatigue, and exertion intolerance. Strategies for the management of viral myocarditis with acute heart failure include pharmacological therapies and mechanical circulatory assist devices if required. Despite multiple available diagnostic methods and treatments, viral myocarditis remains as an etiology of challenging diagnosis, and poor prognosis with a high mortality rate.

Bicuspid Aortic Valve Associated with Severe Aortic Regurgitation and Large Aortic Root Aneurysm.

We described the case of a 30-year-old male who came to the Emergency Department complaining of left shoulder pain and dyspnea under exertion. A bicuspid aortic valve and aneurysm of root and ascending aorta were diagnosed. These were initially managed with medical therapy and ultimately with definitive surgical correction.

Efficacy of a cognitive and behavioral treatment for childhood obesity supported by the ETIOBE web platform.

Recently, the prevalence of childhood obesity has increased alarmingly. Interventions combining eating habits, physical activity (PA), behavioral components, and family support have been shown to be effective, although variables such as self-efficacy beliefs and motivation seem to be important in achieving stable changes. Information and communication technologies (ICTs) can provide additional resources to traditional treatments. The objective is to analyze the efficacy of two treatments: a cognitive and behavioral treatment (CBT) focused on the promotion of healthy eating and PA habits, and this CBT intervention supported by a web platform (ETIOBE). Forty-seven obese children were randomized to these two conditions. Anthropometrical measures were evaluated before and after treatment and at follow-up. Self-efficacy and motivation questionnaires were filled out in the first and last intervention sessions. Mixed ANOVAs were performed for all variables. Simple mediation analyses were conducted to test whether the effect of condition on the post-intervention anthropometrical variable scores were mediated by self-efficacy. Results revealed that both treatments produced an improvement in the anthropometrical variables. CBT-E participants showed more PA self-efficacy as the treatment progressed and lower BMIz, lower fat mass, and higher lean mass. These results suggest that ICT help to improve the effects of childhood obesity interventions.

Hydrogeological responses in tropical mountainous springs.

This study presents a hydrogeochemical analysis of spring responses (2013-2017) in the tropical mountainous region of the Central Valley of Costa Rica. The isotopic distribution of δ18O and δ2H in rainfall resulted in a highly significant meteoric water line: δ2H = 7.93·Î´18O + 10.37 (r2 = 0.97). Rainfall isotopic composition exhibited a strong amount-dependent seasonality. The isotopic variation (δ18O) of two springs within the Barva aquifer was simulated using the FlowPC program to determine mean transit times (MTTs). Exponential-piston and dispersion distribution functions provided the best-fit to the observed isotopic composition at Flores and Sacramento springs, respectively. MTTs corresponded to 1.23 ± 0.03 (Sacramento) and 1.42 ± 0.04 (Flores) years. The greater MTT was represented by a homogeneous geochemical composition at Flores, whereas the smaller MTT at Sacramento is reflected in a more variable geochemical response. The results may be used to enhance modelling efforts in central Costa Rica, whereby scarcity of long-term data limits water resources management plans.
