To examine change from 2000 to 2006 in obesity and overweight by gender, school year and school socioeconomic status (SES) in a national sample of students from Australia.
Survey of students aged 6-18 years from the same 32 schools in 2000 (N = 3,819) and 2006 (N = 5,524) with measured height and weight. All analyses were adjusted for the cluster survey design. Main outcome measures were height, weight, Z-score distribution of BMI, overweight and obesity [International Obesity Task Force (IOTF) cut-offs], school SES.
Obesity and overweight were similar to previous Australian findings with 5.2% and 6.1% obese in 2000 and 2006, respectively, and 16.3 and 19.0% overweight. Significant increase in obesity was observed in students from low SES schools which increased from 5.8 to 8.6% (P < 0.05) compared to 5.5 to 6.3% (P = 0.32) in middle SES and 3.3 to 4.2% (P = 0.92) in high SES schools.
Obesity increased significantly among children in low SES schools and preventive efforts should urgently and carefully target preventive efforts to assist schools, families and communities which are socially and economically, disadvantaged using culturally appropriate physical activity and nutrition promotion interventions.
在澳大利亚全国范围内的学生样本中，按性别、学年和学校社会经济地位（SES），考察 2000 年至 2006 年肥胖和超重的变化情况。
对来自 2000 年（N=3819）和 2006 年（N=5524）的相同 32 所学校的 6-18 岁学生进行了身高和体重的测量，采用横断面调查方法。所有分析均考虑了群组调查设计的影响。主要观察指标为身高、体重、BMI 的 Z 分数分布、超重和肥胖（国际肥胖工作组[IOTF]切点）、学校 SES。
肥胖和超重的比例与之前澳大利亚的研究结果相似，2000 年和 2006 年肥胖的比例分别为 5.2%和 5.8%，超重的比例分别为 6.1%和 6.3%。来自低 SES 学校的学生肥胖率显著增加，从 5.8%增加到 8.6%（P <0.05），而中 SES 学校从 5.5%增加到 6.3%（P=0.32），高 SES 学校从 3.3%增加到 4.2%（P=0.92）。
低 SES 学校儿童的肥胖率显著增加，应紧急而谨慎地针对预防措施，为在社会经济上处于劣势的学校、家庭和社区提供帮助，利用文化上适当的体育活动和营养促进干预措施。
