Mathematical Modeling in Tracking the Connection Between Anthropometric Characteristics and Motor and Functional Abilities as well as Diet Quality of Female Students Age 14 to 18 Years

Obesity and chronic illnesses connected with it, mark health problems of modern times which arise as consequences of poor diets and insufficient physical activity in everyday life. With the employment of mathematical modeling, it is possible to make a connection between anthropometric measurements values, motor tests and functional capability results on one side, and diet quality of specified population groups on the other. For this study, measurements were carried out in a vocational secondary school and the subjects were female students aged 14 - 18 years (N=63). Data on nutritional status as a body mass index, and fat tissue distribution as WHR were derived from anthropometric characteristics. Students were interviewed individually by an examiner, and a quantitative food frequency questionnaire (Q-FFQ) was used. Collected data included consumption frequency (daily, weekly, monthly, etc.) of foods, regarding different foods groups and cooking/processing methods (fresh, boiled, baked/fried, canned, etc.). Descriptive statistics and regression models were employed in the data analysis. A number of principal food group servings was followed, and varied considerably. The number of wheat group servings ranges from 2 to 20/day ; the number of milk and milk drinks group servings ranges from 0 to 5/day and the number of fruits and vegetables groups servings ranges from 0 to 15/day while its mean value is only 2, 05/day. Because of a wide range of serving sizes, computer programming was employed in modeling and in tracing the relation of all considered parameters. Regression models demonstrated that students’ anthropometric data were in positive correlation with their motor and functional abilities as well as with certain food groups consumption. These results confirm the hypothesis that an adequate diet has a positive influence on the motor and functional abilities of individuals which is verified by anthropometric data interaction between nutritional status, described as body mass index, and fat tissue distribution, described as WHR.
