“…Consistent with a previous study by Phanand colleagues evaluating adolescent bariatric surgery candidates, the mean IQ is in the average range (9) . Phanand colleagues failed to show a relationship between BMI and IQ, but examined this association in a much smaller sample (9) . When the two WASI subtests administered in this study were examined independently, only the vocabulary subtest scores were significantly associated with BMI.…”

Background Prior studies have found that students with overweight and obesity have impairments in performance IQ and executive function, and worse school functioning in comparison to normal weight peers. Objectives The current study assessed school and cognitive functioning in a sample of adolescents with severe obesity being evaluated for laparoscopic adjustable gastric banding. Setting: Psychiatry Department, University Medical Center, United States. Methods Eligible candidates for bariatric surgery were referred for psychiatric evaluation which included a semi-structured clinical interview measuring school functioning and the vocabulary and matrix reasoning subtests of the Wechsler Abbreviated Scale of Intelligence (WASI). Results Self-reported school problems were common, with 55.5% of adolescents failing a grade or subject, 38.7% attending summer school, and 17.8% failing a citywide exam. A significant relationship was observed between body mass index (BMI),estimated WASI IQ(r= −0.250, p=0.005), and the vocabulary subtest (r= −0.241, p=0.006), but not matrix reasoning (r= −0.126, p=NS). Conclusions Even among a sample of adolescents with severe obesity, increased BMI was associated with lower WASI IQ and vocabulary subtest scores. Increasing awareness of potential cognitive and school problems in bariatric candidates among teachers, school counselors, and other mental health providers is an important first step to improving academic support and educational systems deficiencies for students with overweight and obesity.

Phan et al (9) also showed that adolescents with obesity seeking bariatric surgery had a mean IQ in the average range; however, 21% of the sample had IQ scores that were borderline or extremely low (double what would be expected in a normative population).…”

“…In line with an adolescent US study (n = 29), we did not find any significant association between baseline cognitive functioning and BMI among our participants. 29 However, a larger (n = 141) US study found that a higher pre-surgical BMI was significantly associated with lower cognitive functioning. 6 …”

Pada anak yang mengalami obesitas selama >6 tahun sebanyak 67,5% memiliki IQ di bawah rata-rata (p<0,001); anak yang mengalami obesitas selama <6 tahun sebanyak 56,8% (p<0,001) sedangkan anak yang tidak pernah mengalami obesitas hanya 4,0%.…”

Background and purpose: The prevalence of obesity among youth in Indonesia was increasing. Obese young people have risk of having noncommunicable disease and also affect the intelligence quotient. This study aims to determine the association between nutritional status and intelligence quotient among junior high school students. Methods: The study was cross sectional with a sample of 176 respondents determined by simple random sampling. Data were collected through an IQ test using Standard Progressive Matrices method, weight and height measurement, and self-administered questionnaires. Data were analysed using Stata. Bivariate analysis using chi-square test and multivariate by poisson regression test. Results: Mean age of respondents was 12.2 years and mean of IQ was 105.8. There were 77 obese students, consisting of 48 (62.3%) males and 29 (37.7%) females. 47 students (26.7%) indicated a below average IQ, consisting of 24 (51.1%) males and 23 (48.9%) females. Bivariate analysis indicated that 55.8% of obese students had below average IQ meanwhile students with a normal nutritional status of 4,0%. On below average IQ 4.0% students never had obesity; 56.8% students <6 years of being obese and 67.5% students ≥6 years of being obese. Multivariate analysis found that respondent’s intelligence quotient was associated with obesity (APR=6.6; 95%Cl: 2.0-21.5). Conclusion: Intelligence quotient was significantly associated with obesity and the period of obesity. The longer the period of being obese more likely had a below average IQ.
