<b>Objectives</b><br/>
Health status and health behaviors are associated with academic achievement in children and adolescents. The purpose of this study was to investigate whether skipping breakfast and being overweight are related to academic achievement of Korean adolescents.<br/><b>Methods</b><br/>
Cross-sectional data on a sample of 1,652 high-school seniors (942 males and 710 females) drawn from the 2004 Korea Education Employment Panel were analyzed.<br/><b>Results</b><br/>
A higher proportion of males (15.3%) than females (6.1%) was overweight (<i>p</i> < 0.001); 37% of males and 41% of females reported skipping breakfast. Overall test scores were significantly higher for females than males (<i>p</i> < 0.05), and in language and foreign language subjects. However, both males and females who reported skipping breakfast had significantly lower scores in language, mathematics, and foreign language than those who did not report skipping breakfast. Overweight males had a lower probability than normal-weight males of having the highest language scores (OR = 0.52, <i>p</i> < 0.05), but there was no difference among females. Females who skipped breakfast had a lower probability of having the highest scores in language (OR = 0.41, <i>p</i> < 0.05), mathematics (OR = 0.24, <i>p</i> < 0.01), or foreign language (OR = 0.18, <i>p</i> < 0.01), while males had a lower probability of having the highest scores in language only (OR = 0.46, <i>p</i> < 0.05).<br/><b>Conclusion</b><br/>
Skipping breakfast and being overweight are associated with poor academic achievement in Korean adolescents. Eating breakfast and weight control is being discussed as the overlooked factors that may influence better academic achievement.

In 2008, Korea Centers for Disease Control and Prevention initiated the first nationwide survey, Korea Community Health Survey (KCHS), to provide data that could be used to plan, implement, monitor, and evaluate community health promotion and disease prevention programs. This community-based cross-sectional survey has been conducted by 253 community health centers, 35 community universities, and 1500 interviewers. The KCHS standardized questionnaire was developed jointly by the Korea Centers for Disease Control and Prevention staff, a working group of health indicators standardization subcommittee, and 16 metropolitan cities and provinces with 253 regional sites. The questionnaire covers a variety of topics related to health behaviors and prevention, which is used to assess the prevalence of personal health practices and behaviors related to the leading causes of disease, including smoking, alcohol use, drinking and driving, high blood pressure control, physical activity, weight control, quality of life (European Quality of Life-5 Dimensions, European Quality of Life-Visual Analogue Scale, Korean Instrumental Activities of Daily Living ), medical service, accident, injury, etc. The KCHS was administered by trained interviewers, and the quality control of the KCHS was improved by the introduction of a computer-assisted personal interview in 2010. The KCHS data allow a direct comparison of the differences of health issues among provinces. Furthermore, the provinces can use these data for their own cost-effective health interventions to improve health promotion and disease prevention. For users and researchers throughout the world, microdata (in the form of SAS files) and analytic guidelines can be downloaded from the KCHS website (<ext-link ext-link-type="uri" xlink:href="http://KCHS.cdc.go.kr/" id="intref0015-main">http://KCHS.cdc.go.kr/</ext-link>) in Korean.
