BACKGROUND
Adolescent weight status is a cumulative effect of health and nutritional problems. Adolescent weight problems often go unnoticed as weight assessment is not considered a priority in adolescents.
OBJECTIVES
To determine the weight status of adolescents using BMI and to identify the contributing factors to adolescent weight problems.
METHODS
In April 2010, 960 adolescents aged 10-19 years in secondary schools in Port Harcourt were selected for the study using a stratified multi-staged sampling method. Structured questionnaires were filled by the investigators while weight and height were measured. BMI was calculated using the formula weight/height2 (kg/m2).
RESULTS
The prevalence of underweight, overweight, obesity and stunting were 6.4%, 6.3%, 1.8% and 5.4% respectively. Factors which were commoner in overweight adolescents were high socioeconomic class, higher maternal education, spending > 3 hours a day watching television and frequent ingestion of snacks.
CONCLUSION
There is a need for periodic weight assessment of adolescents and health education to promote healthy eating habits and regular physical exercise as part of the School Health Programme.
背景
青少年的体重状况是健康和营养问题的累积效应。青少年的体重问题常常被忽视，因为体重评估并不是青少年的首要任务。
目的
使用 BMI 来确定青少年的体重状况，并确定导致青少年体重问题的因素。
方法
2010 年 4 月，采用分层多阶段抽样方法，在哈科特港的中学中选择了 960 名 10-19 岁的青少年进行研究。调查人员填写了结构式问卷，同时测量了体重和身高。BMI 通过公式体重/身高 2（kg/m2）计算得出。
结果
体重不足、超重、肥胖和发育迟缓的患病率分别为 6.4%、6.3%、1.8%和 5.4%。超重青少年中常见的因素是较高的社会经济阶层、较高的母亲教育程度、每天看电视超过 3 小时以及经常吃零食。
结论
需要定期对青少年进行体重评估，并开展健康教育，以促进健康的饮食习惯和定期进行体育锻炼，这是学校卫生计划的一部分。
