Accumulating Sedentary Time and Physical Activity From Childhood to Adolescence and Cardiac Function in Adolescence

BACKGROUND

Increased physical activity (PA) may mitigate the negative cardiovascular health effects of sedentary behavior in adolescents. However, the relationship of PA and sedentary time from childhood with cardiac function in adolescence remains underexplored. Therefore, we investigated the associations of cumulative sedentary time and PA from childhood to adolescence with cardiac function in adolescence.

METHODS AND RESULTS

Participants were 153 adolescents (69 girls) who were aged 6 to 8 years at baseline, 8 to 10 years at 2-year follow-up, and 15 to 17 years at 8-year follow-up. Cumulative sedentary time and PA exposure between baseline and 2-year follow-up and between baseline and 8-year follow-up were measured using a combined accelerometer and heart rate monitor. Cardiac function was assessed using impedance cardiography at 8-year follow-up. The data were analyzed using linear regression analyses adjusted for age and sex. Cumulative moderate to vigorous PA (standardized regression coefficient [β]=-0.323 [95% CI, -0.527 to -0.119]) and vigorous PA (β=-0.295 [95% CI, -0.508 to -0.083]) from baseline to 8-year follow-up were inversely associated with cardiac work at 8-year follow-up. Conversely, cumulative sedentary time had a positive association (β=0.245 [95% CI, 0.092-0.398]). Cumulative vigorous PA from baseline to 8-year follow-up was inversely associated with cardiac work index at 8-year follow-up (β=-0.218 [95% CI, -0.436 to 0.000]).

CONCLUSIONS

Higher levels of sedentary time and lower levels of PA during childhood were associated with higher cardiac work in adolescence, highlighting the importance of increasing PA and reducing sedentary time from childhood.

Functional Outcomes Among Young People With Trajectories of Persistent Childhood Psychopathology

Importance

Understanding which children in the general population are at greatest risk of poor functional outcomes could improve early screening and intervention strategies.

Objective

To investigate the odds of poor outcomes in emerging adulthood (ages 17 to 20 years) for children with different mental health trajectories at ages 9 to 13 years.

Design, Setting, and Participants

Growing Up in Ireland is a longitudinal, nationally representative population-based cohort study. Data collection began in August 2007 and was repeated most recently in September 2018. All results were weighted to account for sampling bias and attrition and were adjusted for socioeconomic factors. Data analysis took place from October 2022 to April 2023.

Exposure

Four latent classes captured variation in mental health in children aged 9 and 13 years, based on the parent-completed Strengths and Difficulties Questionnaire. Classes included no psychopathology, internalizing, externalizing, and high (comorbid) psychopathology. Those who remained in the same class from ages 9 to 13 years were included.

Main Outcomes and Measures

Poor functional outcomes in emerging adulthood were measured at approximate ages 17 years (range, 16 to 18 years) and 20 years (range, 19 to 21 years). Outcomes included poor mental health, poor physical health, social isolation, heavy substance use, frequent health service use, poor subjective well-being, and adverse educational/economic outcomes.

Results

Of 5141 included participants, 2618 (50.9%) were male. A total of 3726 (72.5%) were classed as having no childhood psychopathology, 1025 (19.9%) as having persistent externalizing psychopathology, 243 (4.7%) as having persistent internalizing psychopathology, and 147 (2.9%) as having persistent high psychopathology. Having any childhood psychopathology was associated with poorer functional outcomes in emerging adulthood. The internalizing group had elevated odds of most outcomes except for heavy substance use (range of odds ratios [ORs]: 1.38 [95% CI, 1.05-1.81] for frequent health service use to 3.08 [95% CI, 2.33-4.08] for poor mental health). The externalizing group had significantly elevated odds of all outcomes, albeit with relatively small effect sizes (range of ORs: 1.38 [95% CI, 1.19-1.60] for frequent health service use to 1.98 [95% CI, 1.67-2.35] for adverse educational/economic outcomes). The high psychopathology group had elevated odds of all outcomes (nonsignificantly for frequent health service use), though with wide confidence intervals (range of ORs: 1.53 [95% CI, 1.06-2.21] for poor physical health to 2.91 [95% CI, 2.05-4.12] for poor mental health). Female participants with any psychopathology had significantly higher odds of poor physical health and frequent health service use compared with male participants with any psychopathology.

Conclusions and Relevance

In this longitudinal cohort study, childhood psychopathology was associated with a widespread pattern of functional impairment in emerging adulthood. Findings point to the need for a wider range of preventive interventions in child and adolescent mental health services.

Life Course Cardiovascular Health: Risk Factors, Outcomes, and Interventions

Since it was first defined by the American Heart Association in 2010, cardiovascular health (CVH) has been extensively studied across the life course. In this review, we present the current literature examining early life predictors of CVH, the later life outcomes of child CVH, and the relatively few interventions which have specifically addressed how to preserve and promote CVH across populations. We find that research on CVH has demonstrated that prenatal and childhood exposures are consistently associated with CVH trajectories from childhood through adulthood. CVH measured at any point in life is strongly predictive of future cardiovascular disease, dementia, cancer, and mortality as well as a variety of other health outcomes. This speaks to the importance of intervening early to prevent the loss of optimal CVH and the accumulation of cardiovascular risk. Interventions to improve CVH are not common but those that have been published most often address multiple modifiable risk factors among individuals within the community. Relatively few interventions have been focused on improving the construct of CVH in children. Future research is needed that will be both effective, scalable, and sustainable. Technology including digital platforms as well as implementation science will play key roles in achieving this vision. In addition, community engagement at all stages of this research is critical. Lastly, prevention strategies that are tailored to the individual and their context may help us achieve the promise of personalized prevention and help promote ideal CVH in childhood and across the life course.

Predictors of Adolescents' Response to a Web-Based Intervention to Improve Psychosocial Adjustment to Having an Appearance-Affecting Condition (Young Person's Face IT): Prospective Study

BACKGROUND

Adolescents with a condition affecting their appearance that results in a visible difference can be at risk of psychosocial distress and impaired adjustment. Evidence for the effectiveness of existing interventions in improving psychosocial outcomes is limited, and relevant treatment can be difficult to access. Young Person's Face IT (YPF), a self-guided web-based intervention, has demonstrated potential in reducing social anxiety in adolescents with a visible difference. However, more knowledge is needed about the variables that contribute to variations in intervention effects to identify those who may benefit most from YPF.

OBJECTIVE

This study aimed to investigate demographic, psychosocial, and intervention-related variables as predictors of overall intervention effects after adolescents' use of YPF.

METHODS

We used longitudinal data collected as part of a larger, ongoing mixed methods project and randomized controlled trial (ClinicalTrials.gov NCT03165331) investigating the effectiveness of the Norwegian version of YPF. Participants were 71 adolescents (mean age 13.98, SD 1.74 years; range 11-18 years; 43/71, 61% girls) with a wide range of visible differences. The adolescents completed primary (body esteem and social anxiety symptoms) and secondary (perceived stigmatization, life disengagement, and self-rated health satisfaction) outcome measures at baseline and postintervention measurement. The predictor variables were demographic (age and gender), psychosocial (frequency of teasing experiences related to aspects of the body and appearance as well as depressive and anxiety symptoms), and intervention-related (time spent on YPF) variables.

RESULTS

Two-thirds (47/71, 66%) of the adolescents completed all YPF sessions and spent an average of 265 (SD 125) minutes on the intervention. Backward multiple regression analyses with a 2-tailed P-value threshold of .20 revealed that several variables were retained in the final models and predicted postintervention outcome changes. Body esteem was predicted by age (P=.14) and frequency of teasing experiences (P=.09). Social anxiety symptoms were predicted by gender (P=.12), frequency of teasing experiences (P=.03), depressive and anxiety symptoms (P=.08), and time spent on YPF (P=.06). Perceived stigmatization was predicted by age (P=.09), gender (P=.09), frequency of teasing experiences (P=.19), and depressive and anxiety symptoms (P=.06). Life disengagement was predicted by gender (P=.03), depressive and anxiety symptoms (P=.001), and time spent on YPF (P=.14). Self-rated health satisfaction was predicted by age (P=.008). However, the results were limited by relatively low explained postintervention variance, ranging from 1.6% to 24.1%.

CONCLUSIONS

This study suggests that adolescent boys, adolescents who experience higher levels of psychosocial distress related to their visible difference, and adolescents who spend sufficient time on YPF may obtain better overall intervention effects.

Life's Essential 8: Updating and Enhancing the American Heart Association's Construct of Cardiovascular Health: A Presidential Advisory From the American Heart Association

In 2010, the American Heart Association defined a novel construct of cardiovascular health to promote a paradigm shift from a focus solely on disease treatment to one inclusive of positive health promotion and preservation across the life course in populations and individuals. Extensive subsequent evidence has provided insights into strengths and limitations of the original approach to defining and quantifying cardiovascular health. In response, the American Heart Association convened a writing group to recommend enhancements and updates. The definition and quantification of each of the original metrics (Life's Simple 7) were evaluated for responsiveness to interindividual variation and intraindividual change. New metrics were considered, and the age spectrum was expanded to include the entire life course. The foundational contexts of social determinants of health and psychological health were addressed as crucial factors in optimizing and preserving cardiovascular health. This presidential advisory introduces an enhanced approach to assessing cardiovascular health: Life's Essential 8. The components of Life's Essential 8 include diet (updated), physical activity, nicotine exposure (updated), sleep health (new), body mass index, blood lipids (updated), blood glucose (updated), and blood pressure. Each metric has a new scoring algorithm ranging from 0 to 100 points, allowing generation of a new composite cardiovascular health score (the unweighted average of all components) that also varies from 0 to 100 points. Methods for implementing cardiovascular health assessment and longitudinal monitoring are discussed, as are potential data sources and tools to promote widespread adoption in policy, public health, clinical, institutional, and community settings.

Effect of Stanford Youth Diabetes Coaches' Program on Youth and Adults in Diverse Communities

The Stanford Youth Diabetes Coaches' Program (SYDCP) trains high school students to become diabetes coaches for friends and adult family members. The objective of this study was to assess effects of SYDCP participation on youth and adults from a rural and urban underserved high school community. We used a mixed-methods approach. Patient-Reported Outcomes Measurement Information System (PROMIS) measures for Pediatric Sense of Meaning and Purpose were measured in high school students. PROMIS Adult Global Health and Self-Efficacy was measured in coached adults. Paired t tests compared pre- and postintervention and 6-month follow-up scores. Thematic analysis was used to analyze focus group discussion of adults. Twenty-five students participated, 15 students coached adults with diabetes or prediabetes. Students' sense of meaning and purpose significantly improved postintervention compared to preintervention. Diet and physical activity behaviors improved. Adolescent-adult relationships mediated participation benefits. Our study showed SYDCP improved adolescents' sense of meaning and purpose. In addition, youth and adult relatedness led to improved health behaviors. These findings have important implications, as a sense of purpose and youth-adult connectedness are associated with health behaviors and psychological well-being. Further larger studies of health education programs that engage related youth-adult dyads and assess long-term behaviors and health outcomes are needed.

Association of public care in childhood with social, criminal, cognitive, and health outcomes in middle-age: five decades of follow-up of members of the 1958 birth cohort study

BACKGROUND

Children who have been exposed to public (out-of-home) care experience a range of negative outcomes by late adolescence and early adulthood. The longer-term impact of childhood care is, however, uncertain.

AIM

To examine if there is a prospective association between childhood public care and adverse life outcomes in middle-age.

METHODS

We used data from the UK 1958 birth cohort study of 18 558 individuals. Parents reported offspring care status at age 7, 11 and 16. An array of social, criminal, cognitive, and health outcomes was self-reported by cohort members at age 42 (71% response proportion in eligible sample) and a cognitive test battery was administered at age 50 (62% response).

RESULTS

A total of 420 (3.8%) of 11 160 people in the analytical sample experienced childhood public care by age 16. Net of confounding factors, experience of public care (vs none) was linked to 11 of the 28 non-mutually exclusive endpoints captured in middle-age, with the most consistent effects apparent for psychosocial characteristics: 4/7 sociodemographic (eg, odds ratio; 95% confidence interval for homelessness: 2.1; 1.4 to 3.1); 2/2 antisocial (eg, use of illicit drug: 2.0; 1.2 to 3.5); 2/3 psychological (eg, mental distress: 1.6; 1.2 to 2.1); 1/3 health behaviours (eg, current cigarette smoker: 1.7; 1.3 to 2.2); 2/8 somatic health (physical disability: 2.7; 1.9 to 3.8); and 0/5 cognitive function (eg, beta coefficient; 95% confidence interval for immediate word recall: -0.1; -0.3 to 0.1) endpoints.

CONCLUSIONS

The present study suggests that selected associations apparent between childhood care and outcomes in adolescence and early adulthood are also evident in middle-age.

Lifestyles and Cardiovascular Prevention in Childhood and Adolescence

Pathology studies demonstrated that coronary fatty streaks develop early in life and that even more advanced fibrous plaques are present in a proportion of adolescents. The presence and extent of atherosclerosis in children and adolescents can be correlated with the same risk factors present in adults; as well as, childhood levels of these risk factors predict adult cardiovascular diseases. Children are born with ideal cardiovascular health but, unfortunately, most of them develop over time modifiable behavioral risk factors. Achieving sustained lifestyle changes initiated too late in adults is difficult, and pharmacologic risk factor control cannot fully restore a low-risk state. Therefore, it seems eminently reasonable to initiate healthful lifestyle training as early in life, decreasing the prevalence of cardiovascular risk factors to retard atherogenic processes and reduce the future burden of cardiovascular diseases. Many guideline recommendations encourage universal adoption of healthier lifestyles, identification of children with cardiovascular risk factors, and their treatment using targeted lifestyle modification and, rarely, pharmacotherapy. Major gains will likely accrue from public health strategies targeting incorrect diet, physical activity, and cigarette smoking. Individualized strategies, however, will initially focus on the highest risk children such as those with familial hyperlipidaemia, diabetes, hypertension, and obesity. The primary purpose of this article is to provide a broad overview on the long-term cardiovascular effects of risk factors in children and youth and to outline various lines of evidence for the efficacy of primordial and primary prevention in young people, as well as recommendations for population- and individual-level strategies and evidence-based interventions.
