“…In the correlation analysis a negative correlation was found between BMI and the SPAP average, in line with previous studies where higher BMI correlated with worse academic achievements [71,72]. SPAP average also negatively correlated with RMSSD, pNN50, and SD1, variables related with a parasympathetic modulation.…”

The aim of this study was to analyze the autonomic modulation, physical activity, body mass index, and academic performance of preschool and school students by grade. Extracurricular physical activity, heart rate variability, body mass index, and objective and subjective academic performance were analyzed in 180 preschool and primary school students (7.91 ± 2.29 years). Significant lower heart rate and higher parasympathetic modulation were found in 10–12-year-old primary education students. The 8–9-year-old students obtained the worst results in English and in five of the subjective academic performance items. Students aged 10–12 years old presented the highest body composition values. No significant differences were found on the extracurricular physical activity by age. No correlation between autonomic profile, physical activity, and body composition with objective academic performance was found. Nerveless subjective academic performance perception of teachers presented a negative correlation with body composition and the parasympathetic modulation. School students presented an increased body mass index and parasympathetic modulation by age. Physical activity of all students, independently of the age, were lower than the official recommendations.

“…Our study ndings are consistent with the study, which included American students (n = 57). In that study, students with high BMIs also had lower GPAs [28]. Contradictory to our ndings, academic performance at the University of Kelaniya in Sri Lanka, positively associated with BMI.…”

Background Students' academic performance remains one of the ongoing topics of debate among educators, academicians, and policy-makers. We aimed to assess the effect of dietary habits, demographic characteristics, and body mass index (BMI) on academic performance. Method : An epidemiological, cross-sectional, retrospective study design was conducted. Data were collected from 385 full-time, Saudi undergraduate students at Taibah University aged between 18–24 years old. Students were asked about their breakfast, fast food, and soft drink consumption, and their daily number of meals. Information about their gender, residence in hostels, and smoking status were obtained. Grade point average (GPA) was used to assess academic performance. BMI was also calculated. All statistical analyses were performed using the SPSS software program version 20. Results More females (n = 290; 75.3%) than males were included. High academic performers were non-smokers (P < 0.0005) and didn't stay in hostels (P = 0.026). BMI associated negatively with academic performance. Females had better academic performance (95%) compared to males (58%, P < 0.0005), GPA (2.72 vs 3.53, P < 0.0005 respectively), lower number of meals (Mean: 2.31 vs 1.99), and low prevalence of overweight/obesity (43% vs 30%). Conclusion Nutrition education programs targeting Taibah University students are to be developed to raise awareness about the importance of healthy eating and normal body weight.

“…A systematic literature search was conducted in the PubMed database before November 1 st , 2019 to find meta-analyses of observational studies of education level in relation to diseases studied in the present MR study. We found latest published meta-analysis on 13 diseases and two risk factors, including major depressive disorders 42 , suicide attempts 43 , posttraumatic stress disorder 44 , amyotrophic lateral sclerosis 45 , Alzheimer’s disease 46 , coronary artery disease 47 , heart failure 48 , stroke 49 , breast cancer 50 , prostate cancer 51 , lung cancer 52 , type 2 diabetes 53 , chronic kidney disease 54 , body mass index 55 and hypertension (blood pressure) 56 . We extracted publication data (PMID number, the first author’s name and year of publication), sample size, and risk estimates with their corresponding confidence intervals.…”

Background A deeper understanding of the causal links from education level to health outcomes may shed a light for disease prevention at a novel and efficient perspective. Methods We conducted a wide-angled Mendelian randomization to disentangle the causal role of education level from intelligence for 31 health outcomes and explore to what extent body mass index and smoking mediate the associations. Univariable and multivariable Mendelian randomization analyses were performed. Results Genetically higher education level was associated with lower risk of major mental disorders and most somatic diseases independent of intelligence. The intelligence-adjusted odds ratios for each additional standard deviation of education (4.2 years) were 0.48 (0.37, 0.62) for suicide attempts, 0.50 (0.36, 0.68) for large artery stroke, 0.51 (0.42, 0.63) for heart failure, 0.52 (0.42, 0.65) for lung cancer, 0.45 (0.33,0.61) for rheumatoid arthritis, and 0.48 (0.43, 0.55) for type 2 diabetes. Higher education level adjusted for intelligence was additionally associated with lower risk of insomnia, major depressive disorder, stroke, coronary artery disease, breast cancer, ovarian cancer and gout but with higher risk of obsessive-compulsive disorder, anorexia nervosa, bipolar disorder and prostate cancer. Moreover, higher education level was associated with modifiable health-related risk factors in a favorable manner. Adjustment for body mass index and smoking attenuated the associations between education level and several outcomes, especially for type 2 diabetes and heart failure. High education level exerts causal protective effects on major somatic diseases. Conclusions These findings emphasize the importance of education to reduce the burden of common diseases.
