The relationship among pubertal timing, overweight and obesity and eating disorders in adolescents

School of Public Health, Bengbu Medical College, Bengbu(233000), Anhui Province, China

摘要

摘要: 目的了解蚌埠市青少年超重肥胖、青春发动时相和进食障碍情况及其相互关系，为预防青少年肥胖的发生提供依据。方法在蚌埠市方便抽取2所九年制学校，从五至八年级随机抽取683名学生，采用青春发育量表(PDS)和进食障碍量表(EDI-C)的分量表进行问卷调查，并测量身高、体重等指标，分析超重肥胖、青春发动时相与进食障碍的关系。结果男生超重肥胖率高于女生，女生青春发动时相提前率、瘦身倾向得分、体型不满得分和进食障碍总分高于男生(χ²/t值分别为28.69，57.99，3.47，2.59，3.30，P值均＜0.05)；不同年级学生超重肥胖率、贪食得分和进食障碍总分差异均有统计学意义(χ²/F值分别为28.39，5.11，3.95，P值均＜0.01)。超重肥胖与青春发动时相提前、进食障碍之间呈正相关，青春发动时相提前与进食障碍呈正相关(r值分别为0.18，0.17，0.14，P值均 < 0.01)。青春发动时相提前在超重肥胖与进食障碍之间起的部分中介效应对总效应的贡献率为14.25%。结论青少年超重肥胖与进食障碍相关，青春发动时相提前在超重肥胖与进食障碍之间起部分中介作用。家庭和学校均应倡导健康生活模式，积极预防青少年肥胖、青春发动时相提前和进食障碍行为的发生。

Abstract: Objective To understand the relationship among pubertal timing, overweight and obesity, and eating disorders among Bengbu adolescents, and to provide a reference for obesity prevention. Methods Two nine-year schools were conveniently selected in Bengbu, with 683 students from grade 5 to grade 8. Puberty Development Scale (PDS) and Eating Disorders Inventory of Children (EDI-C) subscale were used, height and weight were measured. The associations between obesity, pubertal timing and eating disorders were analyzed. Results The prevalence of overweight and obesity was higher in boys than that in girls, and the rate of early pubertal timing, drive for thinness score, body dissatisfaction score and total eating disorder score were higher in girls than that in boys(χ²/t=28.69, 57.99, 3.47, 2.59, 3.30, P < 0.05). The differences in rate of overweight and obesity, bulimia score and total eating disorder score were statistically significant by grade(χ²/F=28.39, 5.11, 3.95, P < 0.01). There was a positive correlation among overweight obesity and early pubertal timing and eating disorder, and a positive correlation between early pubertal timing and eating disorder(r=0.18, 0.17, 0.14, P < 0.01). The mediating effect of early pubertal timing between overweiht, obesity and eating disorders partially contributed 14.25% to the total effect. Conclusion Overweight and obesity is associated with eating disorders, and early pubertal timing partially mediate the association between overweight obesity and eating disorders. Healthy lifestyle should be advocated in family and school to effectively prevent adolescents' obesity, pubertal timing, and eating disorders.
