Perception of overweight is associated with poor academic performance in US adolescents.
ABSTRACT To improve understanding of the mechanisms affecting the relationship between adolescent obesity and poor academic performance, we examined the association of overweight or perceived weight status with academic achievement.
We performed a cross-sectional study of 14-17-year-olds (N = 11,012) from the nationally representative 2003 Youth Risk Behavior Survey. The main outcome measure was self-reported grades (mostly A, B, C, D, or F). The primary independent variables were medically defined overweight (body mass index [BMI] ≥ 85th percentile), obesity (BMI ≥ 95th percentile), and participants' perception of their weight status.
Medically defined overweight youth were less likely to report higher grades in unadjusted analysis (OR 0.67, 95% CI: 0.60-0.76, p < .001) and after adjustment for demographics, depression, television and video game use, and physical activity (OR 0.83, 95% CI: 0.74-0.94, p = .003). Statistically significant results also were seen with medically defined obese participants. Youth who perceived themselves as overweight were less likely to report higher grades (OR 0.82, 95% CI: 0.73-0.92, p = .001) in unadjusted analysis and after adjustment for the same variables (OR 0.79, 95% CI: 0.68-0.91, p = .002). The perception of overweight was a more significant determinant of academic performance (OR 0.81, 95% CI: 0.69-0.95, p = .012) compared to medically defined obesity (OR 0.90, 95% CI: 0.77-1.05, p = .174).
Perceived overweight status is negatively associated with academic performance, regardless of actual weight status. These findings suggest that perception of overweight may be a mechanism for prior results indicating a negative association of obesity and academic achievements, and have implications for the academic health of these adolescents.

ABSTRACT: OBJECTIVE--To encourage increased participation in physical activity among Americans of all ages by issuing a public health recommendation on the types and amounts of physical activity needed for health promotion and disease prevention. PARTICIPANTS--A planning committee of five scientists was established by the Centers for Disease Control and Prevention and the American College of Sports Medicine to organize a workshop. This committee selected 15 other workshop discussants on the basis of their research expertise in issues related to the health implications of physical activity. Several relevant professional or scientific organizations and federal agencies also were represented. EVIDENCE--The panel of experts reviewed the pertinent physiological, epidemiologic, and clinical evidence, including primary research articles and recent review articles. CONSENSUS PROCESS--Major issues related to physical activity and health were outlined, and selected members of the expert panel drafted sections of the paper from this outline. A draft manuscript was prepared by the planning committee and circulated to the full panel in advance of the 2-day workshop. During the workshop, each section of the manuscript was reviewed by the expert panel. Primary attention was given to achieving group consensus concerning the recommended types and amounts of physical activity. A concise \"public health message was developed to express the recommendations of the panel. During the ensuing months, the consensus statement was further reviewed and revised and was formally endorsed by both the Centers for Disease Control and Prevention and the American College of Sports Medicine. CONCLUSION--Every US adult should accumulate 30 minutes or more of moderate-intensity physical activity on most, preferably all, days of the weekType: CONSENSUS DEVELOPMENT CONFERENCEType: JOURNAL ARTICLEType: REVIEWLanguage: EngJAMA The Journal of the American Medical Association 03/1995; 273(5):402-407. · 29.98 Impact Factor

ABSTRACT: This is the first in a series of investigations of the social consequences of psychiatric disorders based on the National Comorbidity Survey. Data on the relationship between preexisting psychiatric disorders and subsequent educational attainment are presented. The National Comorbidity Survey is a nationally representative survey of 8,098 respondents in the age range 15-54 years. A subsample of 5,877 respondents completed a structured psychiatric interview and a detailed risk factor battery. Diagnoses of DSM-III-R anxiety disorders, mood disorders, substance use disorders, and conduct disorder were generated, and survival analyses were used to project data on school terminations to the total U.S. population. Early-onset psychiatric disorders are present in more than 3.5 million people in the age range of the National Comorbidity Survey who did not complete high school and close to 4.3 million who did not complete college. The most important disorders are conduct disorder among men and anxiety disorders among women. The proportion of school dropouts with psychiatric disorders has increased dramatically in recent cohorts, and persons with psychiatric disorders currently account for 14.2% of high school dropouts and 4.7% of college dropouts. Early-onset psychiatric disorders probably have a variety of adverse consequences. The results presented here show that truncated educational attainment is one of them. Debate concerning whether society can afford universal insurance coverage for the treatment of mental disorders needs to take these consequences into consideration.American Journal of Psychiatry 08/1995; 152(7):1026-32. · 14.72 Impact Factor

ABSTRACT: Nutritional status, school performance and behaviour were assessed in a group of black, inner-city school children. Thirty-five per cent of the children were obese by triceps skinfold thickness criteria. The primary care taker's responses to the Child Behavior Checklist (CBCL) and the hyperactivity subscale of the Conners' Parent's Questionnaire indicated that the obese children were more likely to have abnormal scores. On the CBCL subscale scores, obese girls had a significantly higher 'sex problems' score. Although the other subscale scores were not significantly different, there was a significant trend for obese boys and girls to score higher on the CBCL subscale scores. In addition, the proportion of obese children placed in special education or remedial class settings was twice that for non-obese children. These results add to the limited information available concerning obese black children, and are consistent with previous findings suggesting subtle behaviour differences in obese children.International Journal of Obesity 06/1994; 18(5):323-7. · 5.22 Impact Factor
