Their height and weight were determined, and they were classified according to seven methods of evaluating nutritional status. The constituent ratios of slender, lean, normal, overweight and fat were calculated, and the validity of evaluation seven methods was analyzed. The differences in the evaluation results of seven methods were analyzed by Chi-squared test. Results The constituent ratios of slender, lean, normal, overweight and fat evaluated by BMI (2) were 2.92%. 2.19%, 86.37%, 3. 65% and 4.87% respectively, the result is in accordance to the practical nutritional status of Chinese female teenager individuals.
