Abstract

Objective To know about the physical health situation of a high vocational college students in Huai Nan city, and relative factors including the dietary etc.. To study the relativity between physical health index and food intake frequency, dietary habit, physical activities. So we can interfere with the physical health situation of the high vocational college students pointedly, and improve the high vocational college students’ nutrition and physical health level.Methods To adopt the epidemiological cross-sectional study method about the college students’ physical health situation and the relative factors that influence the college students’ physical health index. The object of study is the Grade2011students of Medicine Department and Electro Mechanical Department in a high vocational college in Huai Nan city. The selection of the object of study is convenience sampling. There are total650students in Grade2011of Medicine Department and Electro Mechanical Department, there are650Questionnaires issued, and639questionnaires returned, the return rate is98.3%, there are626effective questionnaires, the effective rate is98%;626resident students were carried out food’ etc. relative factors questionnaires survey, and the physical health tests are all effective. In autumn of2011, we carried out the questionnaire survey and physical health test. The questionnaire survey is according to self-edited "College Students’ Food and Physical Health Situation Investigation List". The questions including social demography information, early life development, health-related behaviors, dietary habits, and food intake frequency, physical exercise and labor situations. The physical health test is strictly according to the requirements and provisions of "National Students’ Physical Health Standards". The test equipments are in unification with the students’ physical health test system that the Ministry of Education recommended. The test index includes weight, height, standing long jump, lung’s capacity, the power of gripping (for boy), the body bending on seat (for girl), stair experiment, the test score assessment is according to "National Students’ Physical Health Standards" that was implemented in Sep.,2002. The data is input and consistency detected by EPIDATA3.1, and data analysis is made with SPSS18.0statistical software.ResultsResult of physical health and dietary influence on physical capacity index:Boys’ BMI value is19.60±2.87, girls’BMI value is19.19±1.93; the lung’s capacity value of the boys is3323.32±749.60, the lung’s capacity value of the girls is2235.73±566.10; the vital capacity of body weight for boys is57.04±12.84, the vital capacity of body weight for girls is44.36±11.07; the flexible power index for boys is grip strength test, the value is59.03±11.95, the flexible power index for girls is body bending on seats, the value is14.97±5.92; the endurance test index is stair experiment, the boys’ score is49.41±9.09, and the girls’score is48.26±9.27; the speed and strength index is standing long jumping, the boys’ score is2.00±0.28, and the girls’ score is1.40±0.18. The step test failure rate of boys is higher than girls, and the girls’ failure rate of standing long jumping test and flexible power test is higher than that of boys.From the information of the social demography, the lung’s capacity for boys from urban areas is the biggest (P<0.05). The score of body bending on seat of girls from rural areas is the best (P<0.05).Early life development’s influence on physical capacity index:The boys who was chubby at age of5-6years old and11-12years old, now have the biggest BMI value (P<0.05), which is respectively21.14±3.80,23.42±2.96. The boys who was skinny at age of11-12years old, now have the best standing long jumping score,2.07±0.20(P<0.05); the different degree of the fat and the thin at early development also has influence on the physical fitness test index of girls:the girls who was chubby at the ages of11-12years old have the biggest BMI value now, which is20.87±1.99kg/m2(P<0.05).The difference between dairy intake and boys’s stair experiment score is statistical significant (P<0.05), the stair experiment score is the best with weekly dairy intake2-3times, the value is51.61±10.81; the difference between dietary collocation and girls’BMI value is statistical significant (P<0.05), among them, the girls who take meat as the principal food, have the biggest BMI value, which is22.42±1.37; The difference between breakfast intake frequency and girls’stair experiment score is statistical significant, the girls who almost do not eat breakfast have the best score, which is52.10±16.46per minute. Physical exercise and labor’s influence on physical capacity index:The difference between heavy physical labor time and boys’ grip strength score is statistical significant (P<0.05), the boys who have average heavy physical labor5-8hours, have the best grip strength test score, the value is65.06±10.24kg; For girls, the difference between physical exercise frequency and score of body bending on seat is statistical significant (P<0.05), the girls who have physical exercise frequency over5times each week have the best score of body bending on seat, which is18.35±3.12cm. The relation between BMI and other physical health indexes: Among boys, the ones who have BMI value at normal range, have the biggest lung’s capacity (P<0.05), which is (3503.12±695.58)ml, the boys who are with overweight obesity have the worst stair experiment score (P<0.05), which is (49.21±8.4) per minute and have the best grip strength score (P<0.05), which is (65.426±14.86)kg; Among girls, the ones who are with overweight obesity, have the best lung’s capacity score (P<0.05), which is (2200.55±553.78)ml, and have the minimum score of lung’s capacity BMI, stair experiment, body bending on seats, and standing long jumping (P<0.05), which are respectively (32.92±8.46)ml/kg,(49.21±8.43) per minute, (14.45±5.44)cm,(1.31±0.16)m.Conclusion:1. The percentage of pass of the college students’ physical health index needs improvement, there is still some gaps compared to the whole nation’s level.2. Early development has influence on students’BMI, especially at the age of5-6years old,11-12years old. So we should take measures to prevent obesity from early stage.3. Food has diverse and un-stable influence on the physical capacity index, which need to do deeper and further research4. High strength physical labor can promote the physique of college students5. Overweight obesity will lower the scores of the physical fitness test index.
