To determine the prevalence of overweight and obesity among primary school children in Port Harcourt.
A stratified multi-staged sampling technique was used to recruit pupils from primary schools in Port Harcourt. Data was collected using questionnaires completed by parents. The average of two measurements of height and weight were taken and BMI was calculated manually. Using the BMI for age charts developed by the US National Centre for Health Statistics in collaboration with the National Centre for Chronic Diseases Prevention and Health Promotion, overweight was defined as BMI greater than the 85th but less than the 95th percentile and obesity as BMI equal to or greater than the 95th percentile.
A total of 1302 pupils (585 (44.9%) males and 717 (55.1%) females) were studied. Seventy five (5.8%) of the pupils were overweight while 77 (5.9%) were obese. The prevalence of overweight and obesity of 127 (15.5%) among younger children was higher than that of 25 (5.2%) among the older children (p < 0.001). Female pupils had a higher prevalence of overweight and obesity (12.8%) compared to male pupils (10.3%). A higher prevalence of overweight and obesity was found among the higher (18.1%) than among the lower (2.4%) social class (p < 0.001).
The prevalence of overweight and obesity in primary school children in Port Harcourt, Nigeria is 5.8% and 5.9% respectively. Children from higher socioeconomic class were significantly more overweight and obese than those from lower socioeconomic classes.
确定哈科特港小学生中超重和肥胖的患病率。
采用分层多阶段抽样技术从哈科特港的小学招募学生。通过家长填写问卷收集数据。测量身高和体重两次并取平均值，手动计算体重指数（BMI）。使用美国国家卫生统计中心与国家慢性病预防与健康促进中心共同制定的年龄别BMI图表，超重定义为BMI大于第85百分位数但小于第95百分位数，肥胖定义为BMI等于或大于第95百分位数。
共研究了1302名学生（585名（44.9%）男生和717名（55.1%）女生）。75名（5.8%）学生超重，77名（5.9%）学生肥胖。年幼儿童中超重和肥胖的患病率为127名（15.5%），高于年长儿童中的25名（5.2%）（p<0.001）。女生超重和肥胖的患病率（12.8%）高于男生（10.3%）。社会阶层较高的学生中超重和肥胖的患病率（18.1%）高于社会阶层较低的学生（2.4%）（p<0.001）。
尼日利亚哈科特港小学生中超重和肥胖的患病率分别为5.8%和5.9%。社会经济阶层较高的儿童比社会经济阶层较低的儿童超重和肥胖的情况明显更严重。
