Correlation between physical activity and nutritional status among Chinese children and adolescents

Abstract

Objective To explore the correlation between physical activity and nutritional status of Chinese children and adolescents, and to provide references for the healthy development of Chinese adolescents.

Methods According to the six administrative regions of China (East China, Northwest China, North China, Central China, Southwest China and South China), 4 269 children and adolescents aged 7 to 18 were selected by stratified random sampling method. “Physical Activity Level Evaluation Questionnaire” was used to conduct a physical activity survey. Chi-square test and non-parametric test were used to analyze the physical activity status.

Results The overall detection rate of MVPA insufficiency in children and adolescents with normal BMI were 53.7%, 50.2%, 56.3%, and 52.5% in the wasting group, overweight and obese group, respectively. There was no significant difference in the detection rate of MVPA insufficiency between different nutritional status (χ ² = 2.55, P > 0.05); but in the 7–9 years old age group, the difference in the detection rate of MVPA insufficiency between different nutritional status were statistically significant (χ ² = 10.35, 8.86, 15.88, P < 0.05). There were no significant differences in physical activity intensity and item types under different nutritional status ( P > 0.05).

Conclusion There are age differences in the correlation between physical activity and nutritional status of children and adolescents in my country. Therefore, the differences between different groups should be fully considered while formulating intervention policies.

Abstract

【摘要】 目的 探究中国儿童青少年体力活动与营养状况之间的相关性, 为中国青少年体质健康发展提供参考。 方法 依照中国行政区域划分的六大行政区(华东、西北、华北、华中、西南和华南), 分别采用分层随机整体抽样法抽取22所学 校4 269名7~18岁儿童青少年, 采用“中国7~18岁儿童青少年体力活动水平评价问卷”进行体力活动调查。采用; χ ²检验 和非参数检验对体力活动状况进行分析。 结果儿童青少年体质量指数(BMI)正常组的中高强度体力活动(MVPA)不足 总体检出率为53.7%, 消瘦组、超重组和肥胖组分别为50.2%, 56.3%和52.5%, 不同营养状况之间MVPA不足检出率差异 无统计学意义(χ ² = 2.55, P > 0.05);在7~9岁年龄段中, 男女生及总体各营养状况之间MVPA不足检出率差异均有统计学 意义(χ ²值分别为10.35, 8.86, 15.88, P 值均 < 0.05)。不同营养状况的体力活动强度和项目类型差异均无统计学意义( P值 均 > 0.05)。 结论中国儿童青少年体力活动与营养状况之间的相关性存在年龄差异, 在制定干预政策时应充分考虑不同 群体差异性。
