The bidirectional longitudinal association between academic performance and cardiovascular disease risk factors in adolescents.

INTRODUCTION: The limited prior research examining the association between academic performance and cardiovascular disease (CVD) risk factors in youth did not explore the reciprocal association between these constructs, and analyzed CVD risk factors individually. Thus, the aim of the present study was to explore the bidirectional longitudinal association between clustered CVD risk score and academic performance in adolescents over a 24-month interval. METHODS: A total of 237 adolescents (45.6% girls), aged 13.9 ± 0.3 years old at baseline, from DADOS (Deporte, ADOlescencia y Salud) study were included in this study. A clustered CVD risk score was created by calculating the mean age- and gender-standardized z-scores of waist circumference, systolic blood pressure, total cholesterol to high-density lipoprotein cholesterol ratio, triglycerides, homeostatic model assessment of insulin resistance, and cardiorespiratory fitness (inversed). Academic performance was assessed through the final academic grades and the test of educational abilities. RESULTS: Our results showed that the clustered CVD risk score at baseline was not associated with academic performance 24 months later (all p > .05). Nevertheless, except for physical education, academic grades at baseline were inversely associated with clustered CVD risk score at follow-up in adolescents (ß ranged from -0.140 to -0.102; all p < .05). No associations were found between academic abilities at baseline and clustered CVD risk score at follow-up (all p > .05). CONCLUSION: Academic grades could help predict CVD risk 24 months later during adolescence. Education professionals should foster adolescents' academic performance not only to improve academic results but also to maximize future cardiovascular health benefits.

Bidirectional longitudinal associations of mental health with academic performance in adolescents: DADOS study.

BACKGROUND: The dual-factor model of mental health (i.e., the presence of psychological well-being along with the absence of distress) and its association with academic performance over time has been barely studied in the adolescent population, as most of the prior research focuses on psychological well-being or distress indicators in isolation. The current study analyzed the bidirectional longitudinal association between the dual-factor model of mental health and academic performance in adolescents, comprising a longitudinal assessment 2 years apart. METHODS: A total of 266 secondary school students (13.9 ± 0.3 years at baseline) from Deporte, ADOlescencia y Salud study were assessed. Mental health was assessed through the Behavior Assessment System for Children and Adolescents. Academic performance was assessed through academic grades and the Test of Educational Abilities. A cross-lagged modeling approach was used to examine the bidirectional longitudinal association between mental health and academic performance. RESULTS: Higher academic performance at baseline was associated with better mental health over time, but not vice versa, since this association was not bidirectional. CONCLUSION: Results suggest that academic performance is an important target for developing educational interventions, as it shapes adolescents' mental health at 2 years of follow-up. IMPACT: The overall picture of students' mental health and academic performance was analyzed. Academic performance may be a predictor of adolescents' mental health status. Mental health may not be a predictor of adolescents' academic performance. Good mental health should be promoted among youth with low academic performance.

Relevance of the anterior cingulate cortex volume and personality in motivated physical activity behaviors.

Some recent theories about the origins and maintenance of regular physical activity focus on the rewards of the properties of practicing this activity. Animal and human studies have demonstrated that mesolimbic dopamine plays a crucial role in the involvement in voluntary physical activity. Here, we test this possible role in a sample of 66 right-handed healthy young adults by studying the influence of personality and the volume of reward-related brain areas on individual differences in voluntary physical activity, objectively measured by accelerometer and subjectively self-reported by questionnaire. Our results show that a smaller volume of the right anterior cingulate cortex and lower scores on reward sensitivity contributed to explaining low levels of daily physical activity. Moreover, the volume of the right anterior cingulate cortex correlates positively with self-reported total physical activity. Results are discussed by highlighting the need to use objective measures of daily physical activity, as well as the important role of the anterior cingulate cortex and personality in promoting effortful and invigorating actions to obtain rewards.

The bidirectional longitudinal association between health-related quality of life and academic performance in adolescents: DADOS study.

PURPOSE: Although previous evidence has suggested a relationship between health-related quality of life (HRQoL) and academic performance, the directionality of this association is understudied and remains to be clarified. Thus, the primary objective of this study was to explore the bidirectional association between HRQoL and academic performance in adolescents between two timepoints with a 24-month interval. A secondary aim was to analyze whether this association varies between boys and girls. METHODS: This is a bidirectional longitudinal analysis with 257 adolescents (13.9 ± 0.3 years at baseline) from the DADOS study. HRQoL was measured using the KIDSCREEN-10 questionnaire. Academic performance was assessed through academic grades and the Spanish version of the Science Research Associates Test of Educational Ability. RESULTS: Cross-lagged analyses revealed that HRQoL at baseline was not associated with academic performance 24 months later, while all the academic grades and the overall score of academic abilities at baseline were positively associated with HRQoL at follow-up in adolescents. Results of the stratified analyses by sex were largely similar. Specifically, in girls, math, language, physical education, and grade point average at baseline were positively associated with HRQoL 24 months later, while in boys, all the academic grades indicators (except physical education), numeric ability, and the overall score of academic abilities at baseline were positively associated with HRQoL at follow-up. CONCLUSION: These findings suggest that academic performance in early adolescence may predict HRQoL 24 months later. Health and education professionals could benefit from collaborating to achieve both improved academic performance and HRQoL in youth.

Risk of depression mediates the association between cardiorespiratory fitness and academic performance in adolescent boys and girls: DADOS study.

This study aims to analyze the mediating role of risk of depression in the association between cardiorespiratory fitness and academic performance in a sample of adolescents and to test the moderation effect of sex. A total of 263 adolescents (125 girls, 13.9 ± 0.3 years) from the DADOS (Deporte, ADOlescencia y Salud) study were included in the analysis. Cardiorespiratory fitness was assessed by the 20-m shuttle run test. Academic performance was assessed through the final academic grades and the test of educational abilities. Risk of depression was evaluated through the Behavior Assessment System for Children and Adolescents. Mediation analyses were performed to determine the direct and indirect associations between cardiorespiratory fitness, risk of depression, and academic performance. Indirect effects with confidence intervals not including zero were interpreted as statistically significant, and percentages of mediation were calculated in order to know how much of the association was explained by the mediation. Our findings indicated a significant mediating effect of risk of depression in the association between cardiorespiratory fitness with final grades in math, language, and grade point average (percentages of mediation: 26%, 53%, and 29%, respectively). These analyses were not moderated by sex (all confidence intervals included 0). CONCLUSION: Risk of depression acts as a possible underlying mechanism in the association between cardiorespiratory fitness and academic grades in adolescents. Educational and health institutions could benefit from our findings since the promotion of higher cardiorespiratory fitness levels might reduce the risk of depression with potential benefits on adolescents' academic performance. WHAT IS KNOWN: • Cardiorespiratory fitness is positively associated with academic performance in adolescents. Nevertheless, the psychological mechanisms underlying this association are poorly understood. WHAT IS NEW: • Risk of depression mediates the association between cardiorespiratory fitness and academic performance in adolescents, independently of sex. • Our findings may improve the efficacy of mental health and educational programs by promoting the enhancement of cardiorespiratory fitness levels, which may reduce risk of depression with potential benefits on academic performance.

An examination of the association between risk of depression and academic performance according to weight status in adolescents: DADOS study.

BACKGROUND: The early identification of emotional and psychological problems during adolescence seems helpful to improve academic performance (AP). However, the association between risk of depression and AP, as well as the role of health-related factors in this association remain to be elucidated. Therefore, the aims of this study were to analyze the association between risk of depression and AP in adolescents; to examine this association according to weight status; and to test the mediating role of weight status in this association. METHODS: A sample of 265 adolescents (125 girls) aged 13.9 ± 0.3 years old from the DADOS (Deporte, ADOlescencia y Salud) study was included in the analyses. Risk of depression was self-reported through the Behavior Assessment System for Children and Adolescents. AP was assessed through academic grades and the Spanish version of the Science Research Associates Test of Educational Ability. Weight status was assessed by body mass index (BMI) (kg/m2) and dichotomized according to the international age- and sex-specific BMI cut-offs (non-overweight vs. overweight). RESULTS: Linear regression analyses showed an inverse association between risk of depression and academic grades (all p<0.05). Further linear regressions analyzing risk of depression and AP (dependent variable) stratified by weight status showed stronger associations among overweight adolescents. Additionally, mediation analyses revealed that weight status acted as a mediator of this association. LIMITATIONS: The cross-sectional design prevents from interfering causal relationships. CONCLUSIONS: Educational institutions should promote the early identification of depression as well as the promotion of healthy weight status as strategies to enhance AP in adolescents.
