背景：儿童肥胖是一个新兴的全球公共卫生挑战。印度-亚洲发展中国家的营养转型缺乏证据。我们进行了这些分析，以确定在城市Pakistan.Methods的学龄儿童的营养状况的趋势：从两个独立的人口为基础的代表性调查，城市组成部分的巴基斯坦全国健康调查（NHSP; 1990 - 1994年）和卡拉奇调查（2004 - 2005年），5至14岁的儿童的营养状况的数据进行了分析。使用美国儿童的规范性数据作为参考，比较了两项调查中体重不足（低于年龄参考体重2 SD以上）、发育迟缓（低于年龄参考身高2 SD以上）和超重和肥胖（体重指数（BMI）85百分位数或以上）儿童的年龄和性别标准化患病率（95% CI）趋势。体力活动和超重或肥胖之间的关联进行了分析，在卡拉奇调查使用逻辑回归analysis.Results：2074名儿童被列入城市NHSP和1675在卡拉奇调查。在NHSP和卡拉奇调查中，体重不足儿童的患病率分别为29.7%和27.3%（p=0.12），发育迟缓儿童的患病率分别为16.7%和14.3%（p=0.05），超重和肥胖儿童的患病率分别为3.0和5.7（p < 0.001）。体力活动与超重或肥胖呈负相关（比值比，95%CI，0.51，0.32 - 0.80为那些从事超过30分钟的体力活动与那些从事不到30分钟的活动）。结论：我们的研究突出了巴基斯坦学龄儿童所面临的挑战。尽管营养不良的负担一直很重，但超重和强迫症儿童的人数迅速增加。预防儿童肥胖的重点必须包括促进体育活动的战略。
Background: Childhood obesity is an emerging global public health challenge. Evidence for the transition in nutrition in Indo-Asian developing countries is lacking. We conducted these analyses to determine the trends in nutritional status of school-aged children in urban Pakistan.Methods: Data on the nutritional status of children aged 5 to 14 years from two independent population-based representative surveys, the urban component of the National Health Survey of Pakistan (NHSP; 1990 - 1994) and the Karachi survey (2004 - 2005), were analysed. Using normative data from children in the United States as the reference, trends for age- and gender-standardised prevalence (95% CI) of underweight (more than 2 SD below the weight-for-age reference), stunted (more than 2 SD below the height-for-age reference) and overweight and obese (body mass index (BMI) 85(th) percentile or greater) children were compared for the two surveys. The association between physical activity and being overweight or obese was analysed in the Karachi survey using logistical regression analysis.Results: 2074 children were included in the urban NHSP and 1675 in the Karachi survey. The prevalence of underweight children was 29.7% versus 27.3% (p=0.12), stunting was 16.7% versus 14.3% (p=0.05), and prevalence of overweight and obese children was 3.0 versus 5.7 (p < 0.001) in the NHSP and Karachi surveys, respectively. Physical activity was inversely correlated with being overweight or obese (odds ratio, 95% CI, 0.51, 0.32 - 0.80 for those who engaged in more than 30 minutes of physical activity versus those engaged in less than 30 minutes' activity).Conclusions: Our study highlights the challenge faced by Pakistani school-aged children. There has been a rapid rise in the number of overweight and obsese children despite a persistently high burden of undernutrition. Focus on prevention of obesity in children must include strategies for promoting physical activity.
