Physical inactivity and sedentary lifestyles are known to predispose to overweight and obesity. These lifestyles are also known to track from childhood into adulthood with consequent cardiovascular and metabolic problems. This study aimed to describe the frequency of physical activity and the relationship between physical activity and body mass index of urban Nigerian school children and adolescents.
Children from seven schools in Abeokuta, southwest Nigeria were selected using a multi-staged random sampling technique.
Of 570 children, 411 (72.1%) were involved in moderate to vigorous physical activities. Involvement in physical activity was higher in older children (P<0.001), males (P<0.001), and children of mothers with a higher educational level (P=0.03). Eleven (1.9%) children were overweight or obese whereas 163 (28.6%) were underweight. There were more children with underweight than overweight among the subject population with a high level of physical activity (35.6% vs. 4.4%, P=0.499).
A large proportion of the children in urban Nigeria participate in physical activity. The prevalence of overweight and obesity is low but undernutrition is a major nutritional problem among these children.
体力活动不足和久坐的生活方式已知会导致超重和肥胖。这些生活方式也已知会从儿童期一直持续到成年期，从而导致心血管和代谢问题。本研究旨在描述尼日利亚城市学童和青少年的体力活动频率以及体力活动与体重指数之间的关系。
使用多阶段随机抽样技术从尼日利亚阿贝奥库塔的七所学校中选择儿童。
在 570 名儿童中，有 411 名（72.1%）参与了中等到剧烈的体力活动。体力活动的参与度在年龄较大的儿童（P<0.001）、男孩（P<0.001）和母亲教育程度较高的儿童中更高（P=0.03）。有 11 名（1.9%）儿童超重或肥胖，而 163 名（28.6%）儿童体重不足。在体力活动水平较高的人群中，体重不足的儿童多于超重的儿童（35.6%对 4.4%，P=0.499）。
尼日利亚城市的很大一部分儿童参与体力活动。超重和肥胖的患病率较低，但这些儿童中存在严重的营养不良问题。
