We examined secular trends in physical fitness and BMI status in 8- to 9-year-old Greek children during an 11-year period (1997-2007).
Population data derived from a yearly health survey performed in over 85% of Greek schools. Anthropometric measurements and physical fitness tests from 651,582 children were analyzed. The gender- and age-specific BMI cut-off points by the International Obesity Task Force were used to define overweight/obesity.
Aerobic performance decreased by 4.9% (p < 0.001) for boys and 4.4% (p < 0.001) for girls between 1997 and 2007 while obesity increased by approximately 50% in both genders (p < 0.001). Time-series analyses revealed that the increasing trends in obesity were independent of the reduction in fitness levels. An increase from 21% in 1997 to 48.2% in 2007 was observed in the prevalence of the low quartile of aerobic performance for girls (p < 0.001) and from 25.7% in 1997 to 38.7% in 2007 (p < 0.001) for boys. Approximately 80% and 85% of obese boys and girls, respectively, failed to pass the low quartile of all aerobic tests in 2007.
Inverse but independent trends in obesity and fitness levels were observed among Greek children during an 11-year period (1997-2007), a fact that predisposes our children to serious health risks as they grow older.
我们研究了 8 至 9 岁希腊儿童在 11 年间(1997 年至 2007 年)体能和 BMI 状况的长期趋势。
人群数据来自于希腊 85%以上学校进行的年度健康调查。分析了 651582 名儿童的人体测量数据和体能测试结果。国际肥胖问题工作组(IOTF)制定的性别和年龄特异 BMI 切点用于定义超重/肥胖。
男孩和女孩的有氧能力分别下降了 4.9%(p<0.001)和 4.4%(p<0.001),而肥胖率在两性中均增加了约 50%(p<0.001)。时间序列分析显示,肥胖率的上升趋势与体能水平的下降无关。女孩的低有氧能力比例从 1997 年的 21%上升到 2007 年的 48.2%(p<0.001),男孩的这一比例从 1997 年的 25.7%上升到 2007 年的 38.7%(p<0.001)。2007 年,约 80%和 85%的肥胖男孩和女孩未能通过所有有氧测试的低四分位数。
在 11 年间(1997 年至 2007 年),希腊儿童的肥胖和体能水平呈相反但独立的趋势,这使他们在成长过程中面临严重的健康风险。
