【摘要】：目的了解邯郸城乡小学生身体形态、体成分、骨密度现状,为指导小学生合理营养膳食提供参考。方法使用身高计、电子秤、围度尺、韩国InBody 570体成分分析仪、韩国Osteopro超声骨密度仪,对邯郸市实验小学、曙光小学和邯郸市下属县管辖的乡镇孔村小学、刘村小学、潘村小学的916名12岁小学生进行身体形态、体成分和骨密度测定。结果身体形态指标城市男女生的平均身高(男154.73 cm,女154.56 cm)、体重(男45.34 kg,女43.07 kg)、胸围(男74.18 cm,女73.04 cm)均高于乡村同性别学生的身高(男150.31 cm,女151.17 cm)、体重(男42.08 kg,女40.80 kg)、胸围(男70.37cm,女70.52 cm)(P值均0.01),腰围城市女生(63.51 cm)低于乡村学生(65.28 cm)(P0.05),城市男生(66.85 cm)腰围略高于乡村学生(66.52 cm)(P0.05)。体成分指标城市男女生的平均蛋白质(男6.54 kg,女4.81 kg)、矿物质(男2.14kg,女1.88 kg)、体脂肪含量(男9.75 kg,女11.44 kg)、体脂肪百分比(男21.50%,女26.56%)均高于乡村同性别学生(P值均0.01),城市男女生的水分(男24.05 kg,女21.51 kg)、骨骼肌含量(男15.82 kg,女13.26 kg)、骨骼肌百分比(男34.89%,女30.78%)低于乡村同性别学生(P值均0.01)。骨密度指标城市男女生的平均骨质疏松指数(男54.17,女56.46)、超声速度(男1 374.51 m/s,女1 386.72 m/s)、Z值(男1.48,女1.59)均高于乡村同性别学生(P值均0.01)。结论乡村学生与城市学生相比,生长发育相对迟缓。
[Abstract]:Objective to understand the status of body shape, body composition and bone mineral density of primary school students in Handan. Methods height meter, electronic scale, circumference ruler, InBody 570 body composition analyzer, Osteopro ultrasonic absorptiometry, Handan Experimental Primary School, Shuguang Primary School, Township Kong Village Primary School under Handan prefectural jurisdiction, Liu Cun Primary School were used. Body shape, body composition and bone mineral density were measured in 916 12-year-old primary school students in Pancun Primary School. Results the average height of urban male and female (male 154.73 cm, female 154.56 cm), body weight (male 45.34 kg, female 43.07 kg), chest circumference male 74.18 cm, female 73.04 cm) was higher than that of rural students of the same sex (male 150.31 cm, female 151.17 cm), weight male 42.08 kg, female). 40.80 kg), chest circumference (male 70.37 cm, female 70.52 cm) (P), waist girth urban girls (63.51 cm) lower than rural students (65.28 cm) (P0.05), urban boys (66.85 cm) waist circumference slightly higher than rural students (66.52 cm) (P0.05). The average protein content of male and female (male 6.54 kg, female 4.81 kg), mineral matter) (male 2.14 kg, female 1.88 kg), body fat percentage (male 9.75 kg, female 11.44 kg), body fat percentage) (male 21.50%, female 26.56%) were higher than rural students of the same sex (P all 0. 01). The water content of male and female students (male 24.05 kg, female 21.51 kg),) (male 15.82 kg, female 13.26 kg), skeletal muscle percentage (male 34.89%, female 30.78%) was lower than that of rural students of the same sex (P all 0. 01). The average osteoporosis index (male 54.17, female 56.46), ultrasound velocity (male 1 374.51 m / s, female 1 386.72 m / s) of male and female (male 1.48, female 1.59) were higher than those of rural students of the same sex (P < 0. 01). Conclusion the growth of rural students is slower than that of urban students.
