TAILIEUCHUNG - Research on puberty of Kinh and San Diu students in Vinh Phuc and Phu Tho provinces

This study was designed to be a cross-sectional study of 1440 Kinh students and 718 San Diu students from 11 to 17 years of age in Vinh Phuc and Phu Tho Provinces. The study objective was to determine the age of puberty of Kinh and San Diu students in these provinces. | JOURNAL OF SCIENCE OF HNUE Chemical and Biological Sci. 2014 Vol. 59 No. 9 pp. 148-152 This paper is available online at http RESEARCH ON PUBERTY OF KINH AND SAN DIU STUDENTS IN VINH PHUC AND PHU THO PROVINCES Nguyen Thi Bich Ngoc Faculty of Biology Hanoi National University of Education Abstract. This study was designed to be a cross-sectional study of 1440 Kinh students and 718 San Diu students from 11 to 17 years of age in Vinh Phuc and Phu Tho Provinces. The study objective was to determine the age of puberty of Kinh and San Diu students in these provinces. It was found that Kinh schoolgirls reach puberty at the age of 12 years 10 months and San Diu schoolgirls reach puberty at the age of 13 years 4 months. Kinh students experience their first menstrual flux earlier than San Diu students p lt . Kinh schoolboys reach puberty time at the age of 13 years 5 months and San Diu reach puberty at the age of 14 years 7 months. Kinh male students show signs of puberty earlier than San Diu male students p lt . Female students attain puberty at a younger age than male students p lt . Results from this study can be used as reference material and to teach about characteristic development of school age children in order to improve the quality of care protection and education of children. Keywords Puberty Kinh students San Diu students. 1. Introduction Research on human biology is fundamental and covers a large area requiring the participation of many scientists from different fields such as medicine biology cybernetics chemistry and mathematics. In recent decades many studies on the age of puberty of Vietnamese children have been carried out which have helped determine the age of puberty of Vietnamese young people and provide information that could lead to better education planning strategies and training of future human resources of the country 1 6 9 . The younger generation is the future of every nation. Vietnamese children need improved .
