Nutrition knowledge contributes significantly to the nutritional status and habits of individuals as it influences their food consumption. And body mass index (BMI) of individuals. Recent data suggests a relationship between nutrition and physical activity knowledge, attitude, practices, and anthropometric indices of Ghanaian children.
To determine the relationship between nutrition and physical activity knowledge and using BMI-for-age of school-aged children.
A cross-sectional study involving 591 school-aged children (8-13 years) chosen at random from schools in Ghana's Ho Municipality. Socio-demographic information was gathered. Data on nutrition and physical activity knowledge, attitude, and practice were also collected using structured questionnaires. BMI was calculated after weight and height were measured.
Majority of the participants had poor knowledge on nutrition (46.6%) and physical activity (49.8%) even though more children in private schools (63.3%) had better (good and excellent) knowledge in nutrition than children from public schools (48.2%). Older children (11-13 years) had 'good' knowledge of physical activity (54.7%) as opposed to younger children. Males (59.5%) and children in private schools (66.3%) also had better overall scores in combined nutrition and physical activity knowledge than their female and public-school counterparts, respectively. Physical activity knowledge was significantly (p < 0.05) associated with the BMI-for-age categories. Nutrition knowledge (p < 0.05) and total nutrition and physical activity knowledge scores (p < 0.001) were weakly but positively associated with BMI-for-age.
The results suggest that BMI-for-age of the participants was positively correlated to the nutrition knowledge and the total nutrition and physical activity knowledge (NutPA).
营养知识对个人的营养状况和习惯有重大影响，因为它会影响个人的食物消费以及体重指数（BMI）。最近的数据表明，营养与加纳儿童的体育活动知识、态度、行为以及人体测量指标之间存在关联。
确定营养与体育活动知识之间的关系，并使用学龄儿童的年龄别BMI进行研究。
一项横断面研究，从加纳霍市的学校中随机选取591名学龄儿童（8至13岁）。收集社会人口统计学信息。还使用结构化问卷收集有关营养和体育活动知识、态度及行为的数据。在测量体重和身高后计算BMI。
尽管私立学校中更多儿童（63.3%）在营养方面的知识（良好和优秀）比公立学校儿童（48.2%）更好，但大多数参与者在营养（46.6%）和体育活动（49.8%）方面的知识较差。年龄较大的儿童（11至13岁）对体育活动有“良好”的了解（54.7%），而年龄较小的儿童则不然。男性（59.5%）和私立学校儿童（66.3%）在营养和体育活动综合知识方面的总体得分也分别高于女性和公立学校的同龄人。体育活动知识与年龄别BMI类别显著相关（p<0.05）。营养知识（p<0.05）以及营养和体育活动知识总得分（p<0.001）与年龄别BMI呈弱但正相关。
结果表明，参与者的年龄别BMI与营养知识以及营养和体育活动综合知识（NutPA）呈正相关。
