The influence of some environmental factors on the basic anthropometric indexes of students in Hanoi secondary schools JOURNAL OF SCIENCE OF HNUE Chemical and Biological Sci., 2012, Vol. 57, No. 8, pp. 98-103 This paper is available online at http://stdb.hnue.edu.vn THE INFLUENCE OF SOME ENVIRONMENTAL FACTORS ON THE BASIC ANTHROPOMETRIC INDEXES OF STUDENTS IN HANOI SECONDARY SCHOOLS Mai Van Hung1 and Pham Thi Kim Dung2 1 Center for Anthropology and Intellectual Development, University of Education, Vietnam National University, Hanoi 2 Hanoi University of Education No. 2 Abstract. Study was carried out involving 1200 students (600 male and 600 female) aged 12 to 15. They were enrolled in 3 suburban Hanoi schools and 3 urban Hanoi schools. The results show that in general, the basic anthropometric indexes of suburban Hanoi students are not higher than those of urban Hanoi students. For reasons that effect to anthropometry index of students, except for the influences of genetic, endocrine and race. Environmental factors such as nutrition, psychological influences, physical activitity and economic and natural conditions are important factors which have an effect on the health, morphology and physical status of students.

Economos’ study on the skeletal status of young adults does not well account for moderate as opposed to vigorous physical activity [1]. Roderic Floud, John Komlos, Richard Steckel and Kenneth Sokoloff have looked at human stature in relation to the economic welfare index by human stature and they have seen that height at maturity is a reliable proxy indicator of health and nutritive conditions and that socioeconomic factors as well as hereditary and environmental factors affect growth in terms of height.

In Vietnam, a number of study projects have addressed these problems. For example: “Vietnamese’ physiologic constants in 1975” by Nguyen Tan Gi Trong and et al. [8], “Vietnamese’ anthropometry in 1990” [9], “Project KX 07-07 in 1994”, “Atlas of Vietnamese anthropometry in 1985” and surveys conducted in some areas, provinces, schools, colleges and universities by physiology scientists, influenced particularly by the report “Vietnamese biological values in the 20th Century” by the Ministry of Health of Vietnam [10]. Most previous study has shown that morphological and physical index values are influenced by the environment. H. Nygard and et al. studied the musculoskeletal capacity of employees aged 44 to 58 engaged in physical, mental and mixed types of work in Europe [5]. Sunnegardh and E. Bratterby found the maximal oxygen uptake, anthropometry and physical activity of 8 and 13-year old children in Sweden [7] and the Midtby et al. study looked at variation in bone formation markers with regards to age, gender, anthropometry and season in both men and women [4]. Ritsuko Imamura et al. looked at the effect of wearing long skirts and mini-skirts for a year on subcutaneous fat thickness and body circumference [6]. 2. Content 2.1. Objectives Form and physical force are the most useful indexes used to assess health status. They show actual body status and the relationship between human physiology and environmental factors such as climate, season, nutrition, activity, economy, urbanization and stress. Most previous study has shown that morphological and physical index values are influenced by the environment. The purpose of this study is to identify ecological environment factors that effect the anthropometry of Hanoi students and from there see if there are differences between the anthropometric indexes of students in the Hanoi urban area and students in the Hanoi suburban area, and explain why either urban or suburban Hanoi students got better anthropometric values. 2.2. Time, place and method of study Time period of the study: 1/2012 to 6/2012. This study was carried out on 1200 Hanoi secondary school students (600 male and 600 female) who were from 12 to 15 years old. They were studying in the following schools: - Three schools in suburban Hanoi: Phu Lo Secondary School, Soc Son District; ...
