To investigate the relationship between obesity and gross motor development in children who are developing typically and determine whether body mass index (BMI) predicts difficulty in gross motor skills.
BMIs were calculated and gross motor skills examined in 50 children who were healthy aged 3 to 5 years using the Peabody Developmental Motor Scales, 2nd edition (PDMS-2). Pearson chi-square statistic and stepwise linear hierarchical regression were used for analysis.
A total of 24% of the children were overweight/obese, whereas 76% were found not to be overweight/obese. Fifty-eight percent of the overweight/obese group scored below average on the PDMS-2 compared to 15% of the nonoverweight group. Association between BMI and gross motor quotients was identified with significance of less than 0.002. Regression results were nonsignificant with all 50 subjects, yet showed significance (P = 0.018) when an outlier was excluded.
Children aged 3 to 5 years with high BMIs may have difficulty with their gross motor skills. Further research is needed.
研究发育正常儿童的肥胖与大运动发育之间的关系，并确定体重指数（BMI）是否可预测大运动技能方面的困难。
使用第二版皮博迪发育运动量表（PDMS-2）对50名3至5岁健康儿童计算BMI并检查其大运动技能。采用Pearson卡方统计量和逐步线性分层回归进行分析。
共有24%的儿童超重/肥胖，而76%的儿童未超重/肥胖。超重/肥胖组中58%的儿童在PDMS-2上得分低于平均水平，而非超重组这一比例为15%。BMI与大运动商数之间存在关联，显著性小于0.002。对所有50名受试者进行回归分析结果无显著性，但排除一个异常值后显示出显著性（P = 0.018）。
BMI高的3至5岁儿童在大运动技能方面可能存在困难。需要进一步研究。
