The bidirectional longitudinal association between academic performance and cardiovascular disease risk factors in adolescents. Am J Hum Biol 2024; 36:e24069.

Abstract
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 (β 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.

[PMID: 34482060 DOI: 10.1016/j.jad.2021.08.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Revised: 07/25/2021] [Accepted: 08/21/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Bipolar disorder (BD) has been associated with an increased prevalence of weight gain and abnormally elevated plasma homocysteine (Hcy) levels. However, the relationship between BMI and Hcy in BD patients has not been investigated. This study aimed to explore this relationship in Chinese patients with BD. METHODS Plasma Hcy levels, socio-demographic parameters, clinical and anthropometric data were collected from 195 BD inpatients and 84 healthy controls. The level of plasma Hcy was determined by high-performance liquid chromatography. Body mass index (BMI) was calculated by body weight divided by the square of the height. The participants were divided into a high BMI group and a low BMI group using 24 kg/m2 as a threshold. RESULTS The prevalence of high BMI was slightly elevated in BD patients in comparison to healthy controls. Patients with elevated BMI had significantly higher Hcy levels than patients with low BMI. Hcy level was an independent contributor of the occurrence of high BMI in BD patients. The level of Hcy was positively correlated with BMI in BD patients. In addition, depressive episodes of BD were positively correlated with the prevalence of high BMI and married BD patients were more likely to have high BMI levels. CONCLUSIONS There is a close relationship between BMI and plasma Hcy levels in patients with BD, suggesting that Hcy may be an important indicator for BD-induced weight gain. This finding provides a new avenue for weight management of BD patients and to help avoid the potential risk of cardiovascular diseases.

Longitudinal Effects of Excessive Weight and Obesity on Academic Performance of Primary School Boys in Different Socio-Economic Statuses: The NW-CHILD Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18178891. [PMID: 34501481 PMCID: PMC8431407 DOI: 10.3390/ijerph18178891] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 08/12/2021] [Accepted: 08/16/2021] [Indexed: 11/17/2022]
Abstract
Obesity affects millions of children worldwide and can often impact their academic performance. This longitudinal study, conducted over seven years, determines the effects of excessive weight and obesity on the academic performance of primary school boys, taking into account their socio-economic status (SES). The study forms part of a seven-year (2010–2016) longitudinal study, the North-West Child-Health-Integrated-Learning and Development (NW-CHILD) study, which includes a baseline measurement and two follow-up measurements of the 181 participants from varying areas in the North West Province. Two-way frequency tables, repeated measure ANOVA’s and Spearman rank order correlations were used to analyze the data. The Body Mass Index (BMI) of the participants reported an increase from 2010–2016. Nearly all of the school subjects reported small to large correlations between BMI and academic performance (r ≥ 0.1 and r ≥ 0.3), except for Afrikaans in 2013 (r = −0.06). Only two subjects (English and Language as tested with the ANA test) reported medium effects (r ≥ 0.3), whereas the other subjects only reported small effects (r ≥ 0.1). No statistically significant relationships (p ≥ 0.05) were observed between the BMI values and academic subjects, however SES and school subject scores reported several statistically significant relationships, especially regarding Language (English and First Additional Language) and Mathematics (p = 0.02). Overweight and obese primary school boys in the North West Province of South Africa reported a higher academic performance in comparison to boys of a normal weight, even when SES was taken into consideration. Further studies are recommended to verify current findings regarding weight, obesity and academic performance.

Abstract
BACKGROUND Overweight and obesity contribute to multiple health risks in children, while also impacting negatively on educational performance. Physical fitness can impact outcomes beyond health related measures therefore it can play a mediating role in combating the negative effects of being overweight. METHODS One hundred and seventy-two primary school girls aged 6-13 years old from the North West Province of South Africa formed part of this random stratified longitudinal research design in which three follow-up measurements took place over seven years. Body Mass Index was used to compile obesity profiles, while the progressive aerobic cardiovascular endurance run (PACER) was used to determine cardiovascular fitness. Academic school achievements for grades 1, grade 4 and grade 7, as well as national and provincial values were correlated with academic performance. Data were analyzed by a repeated measure over time ANOVA as well using a latent growth curve model from the structural equation modelling framework (SEM). RESULTS No differences (P>0.05) were found in the academic performance of obese and normal weight girls, although obese girls showed poorer physical fitness values (P<0.05). The SEM model was a good fit for all requirements (RMSEA, 0.60; CMIN DF, 2.837; CFI, 0.966). VO<inf>2</inf>max had a standardized indirect mediation effect (-132) while body composition showing a standardized direct effect (0.183) with academic achievement. Physical fitness showed a mediation effect with regard to obesity and academic achievement in grade 7 girls. CONCLUSIONS Although the academic performance of obese girls did not show impairment before the age of 12 years, physical fitness had a reversible effect on relationships between obesity and academic achievement. This substantial influence of physical fitness should be used strategically in preventive intervention programs necessary to enhance cognitive functioning, academic performance and brain health among overweight children.

Abstract
BACKGROUND Emerging evidence suggests perceptions of being overweight account for many of the psychosocial consequences commonly associated with obesity. Previous research suggests an obesity achievement gap, yet limited research has explored weight perception in association with academic performance. Moreover, underweight perceptions have typically been excluded from research. The current study examined how BMI classification and weight perception relate to academic performance in a large cohort of youth. METHODS We used cross-sectional survey data from 61,866 grade 9-12 students attending the 122 Canadian schools that participated in Year 6 (2017/2018) of the COMPASS study. Mixed effect regression models were used to examine associations between students' BMI classification and weight perceptions and their math and English/French course grades. All models were stratified by sex and adjusted for sociodemographic covariates and school clustering. RESULTS For English/French grades, males and females with overweight or underweight perceptions were less likely to achieve higher grades than their peers with perceptions of being at "about the right weight", controlling for BMI and covariates. For math grades, females with overweight perceptions, and all students with underweight perceptions, were less likely to achieve higher grades than their peers with "about the right weight" perceptions. All students with BMIs in the obesity range were less likely to report grades of 60% or higher than their peers with "normal-weight" BMIs, controlling for weight perception and covariates. Overweight BMIs were predictive of lower achievement in females for English/French grades, and in males for math grades, relative to "normal-weight" BMIs. Results for students that did not respond to the weight and weight perception items resembled those for obesity BMI and overweight/underweight perceptions, respectively. CONCLUSIONS Overall, this study demonstrates that an obesity achievement gap remains when controlling for students' perceptions of their weight, and that both underweight and overweight perceptions predict lower academic performance, regardless of BMI classification. Results suggest barriers to academic success exist among youth with larger body sizes, and those with perceptions of deviating from "about the right weight".

Abstract
The purpose was to examine the association between exercise during pregnancy and intelligence score in offspring. We analyzed data from 4008 women from the Aarhus Birth Cohort, Aarhus University Hospital, Denmark, recruited during pregnancy from July 1989 to November 1991 and their sons who were registered at conscription at 17-20 years of age. The women gave information by self-administered questionnaires during the first trimester including leisure-time physical activity and weekly hours of sport. This information was linked to the sons' measures of intelligence by Børge Priens test scores from the Danish Conscription Registry. Only sons were included since very few women register at conscription in Denmark. The main outcome measure was the Børge Priens test score as a continuous variable and with a low score defined as <10% of the population score. Analyses were adjusted for maternal body mass index, years in school, and smoking. Sons of women with light and moderate to heavy leisure-time physical activity had lower risk of having a low intelligence score compared with sons of women with sedentary activity: adjusted odds ratio (aOR) 0.66 (95% CI 0.49;0.88) and 0.46 (95% CI 0.23;0.93), respectively. Furthermore, sons of women engaged in sports had lower risk of a low intelligence score: aOR 0.50 (95% CI 0.30; 0.83) for 1-2 h/wk and 0.62 (95% CI 0.35; 1.10) for ≥3 h/wk compared with no weekly sports activity. In conclusion, a higher level of physical activity during pregnancy was associated with a lower risk of low intelligence score in early adulthood in sons.

Abstract
BACKGROUND Few studies have analyzed the combined effect of lifestyle factors on academic performance (AP) in adolescents. The aim of this study was to analyze the independent and combined effects of weight status, screen time, sleep quality, daily meal frequency, cardiorespiratory fitness, and physical activity (PA) on AP in adolescents. METHODS A total of 262 adolescents (13.9 ± 0.3 years) from the DADOS study were included in the analysis. Weight status was assessed through body mass index (kg/m2). Participants completed questionnaires to evaluate screen time, sleep quality, and daily meal frequency. Cardiorespiratory fitness was assessed by the 20-m shuttle run test. PA was evaluated by a wrist-worn GENEActiv accelerometer. AP was assessed through the final academic grades and a validated questionnaire. RESULTS Non-overweight status, low screen time, good sleep quality, and proper meal frequency showed independent, positive influence on AP. Moreover, adolescents achieving at least three healthy lifestyles were more likely to be in the high-performance group for academic grades than those achieving ≤1 (math OR: 3.02-9.51, language OR: 3.51-6.76, and grade point average OR: 4.22-9.36). CONCLUSIONS Although individual healthy lifestyles are independently and positively associated with AP, the cumulative effect of multiple healthy lifestyles have a stronger impact.

Abstract
The current study was designed to examine one possible weight stigma-reduction mechanism: school-level weight diversity. It was hypothesized that greater weight diversity among same-sex peers at school would attenuate the negative association between weight and academic achievement. Across 26 urban public middle schools, 5,991 sixth-grade students (52% girls) were included: 12% African American/Black, 14% East/Southeast Asian, 30% Latino, 21% White, and 23% from other specific ethnic groups. Weight diversity was estimated as the likelihood that two randomly selected students would be from different weight categories, using Simpson's index. Standardized achievement test scores and grade point average (GPA) were used to assess academic achievement. Consistent with our contextual moderator hypothesis, high levels of weight diversity at school served a protective function. The negative association between body mass index (BMI) and achievement test scores, as well as GPA (girls only) was nonsignificant at schools with high levels of weight diversity. The study results offer a potential explanation for inconsistent findings regarding body weight and achievement, and a novel methodological approach to capture weight diversity in ways that provide new insights for school-based interventions.

Abstract
Concerns about children’s weight have steadily risen alongside the manufacture and use of myriad chemicals in the US. One class of chemicals, known as metabolic disruptors, interfere with human endocrine and metabolic functioning and are of specific concern to children’s health and development. This article examines the effect of residential concentrations of metabolic disrupting chemicals on children’s school performance for the first time. Census tract-level ambient concentrations for known metabolic disruptors come from the US Environmental Protection Agency’s National Air Toxics Assessment. Other measures were drawn from a survey of primary caretakers of 4th and 5th grade children in El Paso Independent School District (El Paso, TX, USA). A mediation model is employed to examine two hypothetical pathways through which the ambient level of metabolic disruptors at a child’s home might affect grade point average. Results indicate that concentrations of metabolic disruptors are statistically significantly associated with lower grade point averages directly and indirectly through body mass index. Findings from this study have practical implications for environmental justice research and chemical policy reform in the US.
