The social context moderates the relationship between neighborhood safety and adolescents' activities

The Role of the Perceived Neighborhood Social Environment on Adolescent Sedentary Behavior and Physical Activity: Findings from Add Health

Few studies have examined the role of perceived neighborhood characteristics such as neighborhood safety, social cohesion, and contentedness on sedentary behavior (SB) and physical activity (PA) among adolescents. Furthermore, no studies have investigated how these associations are moderated by gender and race. This study aimed to examine the associations of the perceived neighborhood social environment with (SB) and moderate-to-vigorous physical activity (MVPA). Data from 6504 adolescents (aged 15.4 ± 0.03 years) who participated in the National Longitudinal Study of Adolescent Health was used. SB and PA were considered continuously and dichotomously. PNSE variables include safety, social cohesion, and contentedness, where higher values of PNSE indicate a more favorable neighborhood perception. Weighted linear and logistic regression models were used to examine the association of PNSE with continuous total SB (hours/week) and MVPA (bouts/week), and binary excessive SB (14 h/week) and meeting MVPA guidelines (≥ 5 bouts/week), respectively. Associations were stratified by gender and race to test moderation effects. Models were adjusted for demographic, health, parental, and neighborhood covariates. This study found that neighborhood safety and contentedness were negatively associated with SB, whereas neighborhood social cohesion and contentedness were positively associated with PA. Gender-specific and race-specific results remained somewhat consistent with overall findings; however, neighborhood safety was not associated with SB among female and non-White adolescents, respectively. Similarly, neighborhood safety and contentedness were not associated with MVPA for non-White adolescents. Findings suggest that an adolescent's neighborhood environment, gender, and race should be considered when implementing strategies to reduce SB and increase PA.

Contextual Factors Influencing Young Athletes’ Decision to Do Physical Activity and Choose a Sports’ Club: The Case of Portugal

Physical activity and sports are a central part of individuals’ lives throughout the life cycle. During adolescence, its regular practice may contribute to the development of healthy adult lifestyles, decreasing chronic disease incidence. Therefore, the reasons that drive adolescents to start practicing sports in a certain club may be multiple and understanding such causes can be important to design and implement public policies to promote active lifestyles for everyone. In this article, we report the core findings of a research on why young athletes do sports, how they choose their team-training club and how COVID-19 has had an impact on their routines. From a methodological viewpoint, a questionnaire was developed and sent to sport clubs located in NUTS2 Centro Region, Portugal, and results were analyzed through the use of geographic information systems and statistical analysis, namely association tests (Chi-square test), difference tests (Mann–Whitney test and Kruskal–Wallis test), logistic regression and descriptive analysis. Findings show that family, age group, friends, proximity to sports facilities, teammates, and club conditions are the factors that influence adolescents the most. In short, external factors have a significant preponderance to practice physical activity and choose a sports’ club. These findings can provide useful insights for clubs, coaches and policy-makers to become more aware of the relationship between sports practice and accessibility to sports halls, as well as the athletes’ behavior and their connection with the club and basketball practice. As such, these findings can motivate the design of initiatives and strategies to boost sports practice and to find ways for clubs to attract more adolescents.

External food cue responsiveness and emotional eating in adolescents: A multimethod study

Eating in response to external food cues (i.e., external eating) and internal emotional experiences (i.e., emotional eating) are associated with obesity. While external and emotional eating co-occur, little is known about how external food cue responsiveness may interact with internal emotional cues to influence eating episodes in adolescents. The current study examined how trait-level external food cue responsiveness modulates momentary associations between affective states and eating in adolescents. Participants were drawn from a prior study of siblings (N = 78; ages 13-17) who completed an ecological momentary assessment protocol to assess eating episodes and affective states. External food cue responsiveness was determined by comparing energy consumption following presentation of an appetizing food (pizza) on one day and a control activity (reading) on another day. Generalized linear mixed models examined positive and negative affective states, cue responsiveness, and their interactions as predictors of the likelihood of eating. The relationship between affective states and likelihood of eating was stronger among adolescents with higher versus lower external food cue responsiveness. Among adolescents with higher cue responsiveness, endorsing negative affect was associated with a lower likelihood of eating, whereas endorsing positive affect was associated with a higher likelihood of eating (within-person effects). Findings suggest that high sensitivity to external food cues and greater proclivity for emotional eating may be likely to coincide such that any cue, internal or external, is likely to disrupt sensitivity to internal hunger and satiety signals. Future studies are needed to elucidate how sensitivities to internal and external cues may interact to influence obesity risk.

Weight discordant siblings' ability to reduce energy intake at a meal as compensation for prior energy intake from sugar-sweetened beverages (SSBs)

BACKGROUND

Insufficient compensation for energy from sugar-sweetened beverages (SSBs) consumed prior to meals may promote greater overall energy intake. If so, ability to compensate for prior energy intake may account for difference in adiposity between adolescents with and without overweight. Studies of fraternal siblings discordant for weight status control for some genetic and shared within-family factors, which allows for testing how putative non-shared factors, such as parental control of feeding, predicts sibling weight differences.

AIM

To determine whether same-sex weight-discordant (one with, one without overweight) adolescent siblings differ in ability to compensate for prior energy intake.

METHODS

Same-sex biological sibling pairs (mean age = 15.4; 95% confidence interval (CI) 15.1, 15.7) (n = 38 pairs; 21 male pairs) consumed a sugar-sweetened (450 kcal) or a non-nutritive-sweetened (10 kcal) liquid preload of equal volumes on separate days, followed by an ad libitum lunch. Multilevel models examined ability to compensate, dietary restraint, and parental control of child's feeding.

RESULTS

Siblings showed insufficient compensation and overate (with overweight = 44 kcal; without overweight = 32 kcal). Siblings shared little within-family similarity in compensation (intra-class correlation coefficient (ICC) = 0.20). Compensation was predicted by parental restriction and general restriction (p = 0.02) Differences in siblings' BMI z-scores were associated with differences in dietary restraint (p = 0.04) not with differences in compensation.

CONCLUSION

Sibling differences in compensation for energy from sweetened beverages were not associated with differences in their adiposity. Compensation may be determined by a constellation of factors, including age, parental feeding practices, and food characteristics.

Associations between objective physical activity and emotional eating among adiposity-discordant siblings using ecological momentary assessment and accelerometers

BACKGROUND

Emotional eating is associated with obesity, though less is known regarding factors that predict emotional eating episodes in children and adolescents.

OBJECTIVES

To investigate whether moderate to vigorous physical activity (MVPA) or total activity counts 60 minutes prior to psychological stress predicted stress-related eating and positive emotional eating (ie, eating while happy), and whether adiposity (z-BMI) moderated these associations.

METHODS

Participants were drawn from a prior study of siblings (N = 77; mean age = 15.4 ± 1.4 years) discordant for weight status (39 non-overweight siblings, 38 siblings with overweight/obesity) who completed an ecological momentary assessment protocol with accelerometer-based assessment of physical activity.

RESULTS

Greater MVPA was associated with lower stress-related eating across the sample. Lower total activity (between-person effects) and lower MVPA (within-person effects) were associated with greater stress-related eating for siblings with greater z-BMI. Greater total activity was associated with lower positive emotional eating for siblings with lower z-BMI (between- and within-person).

CONCLUSIONS

Findings demonstrate potential regulating effects of prior physical activity on emotional eating at the individual and momentary level, though there are nuances depending on z-BMI. Future work is needed to examine underlying mechanisms and timescale of effects, and particularly the extent to which enhancing MVPA time among youth with z-BMI may mitigate momentary risk of stress-related eating episodes.

The Direct and Indirect Relationships of Environmental, Interpersonal and Personal Factors with High School Students Physical Activity: An Ecological Approach

BACKGROUND

Across countries, young people are not sufficiently physically active. The evidence confirms that beyond demographic and individual agents, individuals participate within their social and physical environment. The ecological model enables a search for the modifiable factors in specific populations, as it allows consideration of factors affecting individuals' lives on different levels, as well as considering the interplay of those factors. The aim of this study was to examine the complex interconnections among environmental, social capital and motivational factors at different levels, within an ecological model for high school students' moderate-to-vigorous physical activity during their leisure time.

METHODS

This cross-sectional population-based study included 1285 students from 14 to 18 years old, with a mean age of 16.14 ± 1.22. Physical activity, neighborhood physical activity recourses, neighborhood safety, social capital, physical activity motivation and sociodemographic factors were evaluated. Logistic regression, mediation and moderation analyses were performed predicting moderate-to-vigorous physical activity during leisure time.

RESULTS

In the final multivariate logistic regression model, greater social participation (OR 1.03 [1.01-1.05]), higher relative autonomy index (OR 1.11 [1.06-1.15]) and male gender (OR 1.71 [1.13-2.57]) directly predicted meeting MVPA recommendations. Any significant moderation effects (p > 0.05) of environmental characteristics were not found for the relationship between social capital, motivational factors and moderate-to-vigorous physical activity. The evidence of positive indirect mediation effects was found in all five models for social capital components as all CIs for its βs do not contain 0, though standardized effect sizes were between 0.02 and 0.07, indicating small effect sizes.

CONCLUSION

These findings provide support for the presence of some direct and indirect pathways from social capital to moderate-to-vigorous physical activity. Future intervention strategies should focus on strengthening physical activity motivation by encouraging the development of social network and social participation as well as family, neighborhood and school social capital within the framework of the ecological model.

Influence of Neighborhood Environment on Physical Activity Participation among Children with Autism Spectrum Disorder

Despite the positive influence of environmental factors on physical activity (PA) levels of children, further investigation is necessary when considering the unique characteristics of children with autism spectrum disorder (ASD). The purpose of this study was to examine the relationship between neighborhood environment factors and PA among children with ASD by examining the extent to which (a) the built environment, (b) neighborhood safety, and (c) neighborhood support contributes to PA. A secondary data analysis using the 2016 and 2017 combined dataset of the National Survey of Children's Health was used. The total sample included 14,944 children between the ages of 6-17 years; of this, a sample of 494 children had a parent-reported diagnosis of ASD. Multivariate logistic regressions were conducted to explore the unique influences of the above three neighborhood environment factors on PA engagement. Among children with and without ASD, an association was found between feeling safe and engaging in PA, that is, the odds of engaging in PA are greater among children who were safe in their neighborhoods than children who were not in safe neighborhoods. Surprisingly, other neighborhood factors do not have a significant relationship with PA participation among children with ASD at this time. Future studies should consider how to incorporate the support of others and feeling of safety into the neighborhood along with how to improve accessibility of the built environment in order to increase PA for children with ASD. LAY SUMMARY: The results of this study showed that neighborhood factors influence physical activity (PA) among children with ASD differently compared to their peers without ASD. Children with ASD who live in safe neighborhoods are more likely to engage in PA, while other neighborhood factors, such as playgrounds and support, are not associated with an increased likelihood of engaging in PA at this time. Efforts should be made to improve neighborhood accessibility and design in order to increase PA among children with ASD.

Are neighborhood characteristics associated with sedentary behavior in adolescents? A systematic review

Sedentary behavior (SB) has emerged as a potential risk factor for chronic diseases. SB includes activities requiring low energy expenditure (≤1.5 metabolic equivalents) performed in a sitting or reclining posture. Our study aimed to gather evidence on the association between SB outcomes in adolescents (10-19 years) and neighborhood characteristics. This systematic review (PROSPERO registration number: CRD42018076877) examined studies indexed in PubMed Central®, LILACS, ScienceDirect, and SPORTDiscus databases. Sixteen articles were included. Insecurity during daytime hours, crime incidence, physical and social disorders, a higher neighborhood socioeconomic level, and time spent with peers were associated with higher levels of SB. Traffic, availability of a favorable environment for physical activity, and higher residential density were associated with lower levels of SB. Despite great variability in the SB cutoff points and methodology used for evaluating SB and neighborhood characteristics among studies, the evidence suggests that adolescent SB might be influenced by neighborhood characteristics.

Annual Research Review: Ecological momentary assessment studies in child psychology and psychiatry

BACKGROUND

Enhancements in mobile phone technology allow the study of children and adolescents' everyday lives like never before. Ecological momentary assessment (EMA) uses these advancements to allow in-depth measurements of links between context, behavior, and physiology in youths' everyday lives.

FINDINGS

A large and diverse literature now exists on using EMA to study mental and behavioral health among youth. Modern EMA methods are built on a rich tradition of idiographic inquiry focused on the intensive study of individuals. Studies of child and adolescent mental and behavioral health have used EMA to characterize lived experience, document naturalistic within-person processes and individual differences in these processes, measure familiar constructs in novel ways, and examine temporal order and dynamics in youths' everyday lives.

CONCLUSIONS

Ecological momentary assessment is feasible and reliable for studying the daily lives of youth. EMA can inform the development and augmentation of traditional and momentary intervention. Continued research and technological development in mobile intervention design and implementation, EMA-sensor integration, and complex real-time data analysis are needed to realize the potential of just-in-time adaptive intervention, which may allow researchers to reach high-risk youth with intervention content when and where it is needed most.

A Review of Current Ambulatory Assessment Studies in Adolescent Samples and Practical Recommendations

The use of ambulatory assessment (AA) and related methods (experience sampling, ecological momentary assessment) has greatly increased within the field of adolescent psychology. In this guide, we describe important practices for conducting AA studies in adolescent samples. To better understand how researchers have been implementing AA study designs, we present a review of 23 AA studies that were conducted in adolescent samples from 2017. Results suggest that there is heterogeneity in how AA studies in youth are conducted and reported. Based on these insights, we provide recommendations with regard to participant recruitment, sampling scheme, item selection, power analysis, and software choice. Further, we provide a checklist for reporting on AA studies in adolescent samples that can be used as a guideline for future studies.

The role of maternal social networks on the outcomes of a home-based childhood obesity prevention pilot intervention

BACKGROUND

Despite evidence that obesity and related behaviors are influenced by social networks and social systems, few childhood obesity initiatives have focused on social network factors as moderators of intervention outcomes, or targets for intervention strategies.

OBJECTIVES

This pilot study examines associations between maternal social network characteristics hypothesized to influence health behaviors, and the target outcomes of a family-centered childhood obesity prevention initiative. The pilot intervention entailed the provision of healthy eating and activity components as part of an existing home visiting program (HVP) delivered to mothers and infants, to test the feasibility of this approach for improving mother diet, physical activity, and weight status; and infant diet and weight trajectory.

METHODS

Mothers and their infants (N=50 dyads) receiving services from our HVP partner were recruited and randomized to receive the HVP core curriculum with or without a nutrition and physical activity enhancement module for six months. Assessments of mothers' social network characteristics, mother/infant food intake and mother physical activity, and mothers' postpartum weight retention and children's growth velocity were conducted at baseline and post-intervention.

RESULTS

Several features of mothers' social networks, including the receipt of health-related social support, were significantly associated with the focal intervention outcomes (p < .05) at follow-up, controlling for study condition.

CONCLUSIONS

Integrating childhood obesity prevention into HVPs appears promising. Future family-based interventions to prevent childhood obesity may be enhanced by including social network intervention strategies. For example, by addressing family network characteristics that impede healthy behavior change, or enhancing networks by fostering social support for healthy behavior and weight change.

Eating Responses to External Food Cues in Weight Discordant Siblings

PURPOSE

Heightened responsivity to external food cues may promote energy intake and account for differences in weight status between nonoverweight and overweight adolescents. Studies of weight-discordant fraternal siblings control for some genetic and shared within-family factors, which allow for testing of other nonshared factors relevant to sibling weight differences.The aim of the study was to determine whether same-sex weight-discordant (one nonoverweight and one overweight) adolescent siblings differ in responsiveness to external food cues.

METHODS

Weight-discordant siblings' (n = 38 pairs) energy consumption was compared following both an appetizing food (pizza) on one day and a control activity (reading) on another day. Multilevel models examined intrafamily similarity, and regressions examined associations with adiposity.

RESULTS

Siblings shared little similarity in cue responsivity (ρ = .10). However, sibling body mass index z-scores difference was not associated with differences in cue responsivity. Moreover, when tested as groups, nonoverweight and overweight siblings did not differ for cue responsivity (p > .84).

CONCLUSION

Weight-discordant adolescent siblings show little similarity in responses to food cues. Differences in sibling weight status were not predicted by differences in responses to food cues. Thus, nonshared factors other than cue responsivity must contribute to weight differences of adolescent siblings.

Reciprocal associations between screen time and emotional disorder symptoms during adolescence

Screen-based sedentary behaviors and emotional disorders are associated with one another in youth. Yet, the direction of the association is unclear, as is whether specific types of screen-based sedentary behaviors and emotional disorder symptoms are more closely linked. This study estimated the bi-directional associations between two types of screen-based sedentary behaviors and four types of self-reported emotional disorder symptoms, and tested whether physical activity buffered these associations in a Los Angeles high school student cohort (N = 2525, baseline Mage = 14.6 years). Participants completed baseline (9th Grade, 2013) and 12-month follow-up (10th grade, 2014) surveys reporting on: television viewing and computer/videogame use (≥4 h/day; yes/no), physical activity (≥60 min/day for ≥5 days/week), and Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), Panic Disorder (PD), and Social Phobia (SP) symptoms (meet/exceed [sub]clinical symptom threshold; yes/no). After adjusting for baseline screen-based sedentary behavior and covariates, students with (sub)clinical baseline MDD and GAD were at increased odds of high computer/videogame use one year later (OR = 1.36[95%CI, 1.07-1.73]; OR = 1.36[95%CI,1.09-1.71], respectively). Baseline SP was marginally related to increased computer/videogame use at follow-up (OR = 1.33[95%CI,1.04-1.69]). Greater baseline computer/videogame use was associated with increased odds of (sub)clinical GAD (OR = 1.54[95%CI,1.23-1.94]) and (sub)clinical SP (OR = 1.64[95%CI 1.27-2.12]) at follow-up; these associations were suppressed among baseline physically active students. Television viewing was unrelated to emotional disorder symptoms and PD was not associated with screen-based sedentary behaviors. Thus, only reciprocal associations between computer/videogame use, SP, and GAD during a one-year period of adolescence were observed. Interventions reducing computer/videogame use and increasing physical activity may improve adolescent emotional health.
