Abstract: Objective To understand the nutrition status of children in Shandong in 2010, and to analyze the correlation between overweight, obesity, wasting and the level of physical fitness. Methods According to the students constitution and health survey data of Shandong students in 2010, the normal weight, overweight, obesity and wasting children were screened out based on body mass index (BMI);the central obesity and general obesity were divided based on waist circumference (WC).Controlled for gender and sex, the correlation between different nutrition status and physiological functions, athletic ability through partial correlation and covariance were analyzed. Results The prevalence of overweight, obesity and wasting were 14.7%, 11.4% and 7.9%, respectively;central obesity and general obesity were 77.4% and 22.6% respectively in obese children.Controlled for gender and sex, BMI & WC were positively correlated with systolic blood pressure, diastolic blood pressure, 50 meters run time, endurance run time(P<0.01);and were negatively correlated with spiro-index, grip index, sit-ups, standing long jump(P<0.01).Covariance analysis showed that the average levels of physiological functions and athletic ability of overweight, obesity and wasting group students had lower levels than the students with normal BMI, central obesity group students were lower than the general obesity. Conclusions Undernutrition and overnutrition coexisted among the children and adolescences in Shandong in 2010;overweight, obesity and wasting can lead to the decline of physiological functions and athletic ability;central obesity have greater influence on physical fitness than general obesity.
