Ecuador is undergoing a nutrition tran- sition where overweight/obesity coexist with under-nutrition. The objective of this study was to determine nutritional status, physical activity, fruit and vegetables consumption frequency among school-going adolescents in the canton of Paute and further explore if these variables were differential by urban vs. rural residence. We conducted a cross-sectional study using a random sample of students aged 12 to 19 years from the only two public secondary schools in the canton Paute. We determined nutritional status according to the World Health Organization criteria. Demographics, physical activity habits, fruit and vegetable consumption frequency were determined by questionnaires. Of the total of 314 students, 44.9% lived in urban area and 55.1% in rural area. The prevalence of overweight/obesity was significantly higher among students with urban vs. rural residence (28.4% vs. 17.9%; P=.03). The prevalence of stunting was significantly higher among students with rural vs. urban residence (31.8% vs. 16.3%; P=.002). There were no significant differences detected between groups in the frequency of consumption of fruits and vegetables. Urban residence was asso- ciated with a greater mean number of minutes of outdoor recreation after school (76.0 minutes vs. 57.1 minutes; P=.02), greater weekly hours of planned physical activity (2.0 hours vs. 1.6 hours; P=.007), and greater daily screen time in front of a television or computer (3.2 hours vs. 2.5 hours; P<.001). Interventions to prevent or reduce overweight/obesity in Paute and other similar areas with students from both urban and rural areas should consider place of residence in their design.
厄瓜多尔正在经历营养转型,超重/肥胖与营养不良并存。本研究的目的是确定保特县学龄青少年的营养状况、身体活动、水果和蔬菜消费频率,并进一步探讨这些变量在城市与农村居民之间是否存在差异。我们进行了一项横断面研究,从保特县仅有的两所公立中学中随机抽取了12至19岁的学生样本。我们根据世界卫生组织的标准确定营养状况。通过问卷调查确定人口统计学、身体活动习惯、水果和蔬菜消费频率。在总共314名学生中,44.9%居住在城市地区,55.1%居住在农村地区。城市居民学生中超重/肥胖的患病率显著高于农村居民学生(28.4%对17.9%;P=0.03)。农村居民学生中发育迟缓的患病率显著高于城市居民学生(31.8%对16.3%;P=0.002)。两组在水果和蔬菜消费频率上未发现显著差异。城市居住与放学后更长的平均户外娱乐时间相关(76.0分钟对57.1分钟;P=0.02),每周计划的体育活动时间更长(2.0小时对1.6小时;P=0.007),以及每天在电视或电脑前的屏幕时间更长(3.2小时对2.5小时;P<0.001)。在保特及其他有城乡学生的类似地区,预防或减少超重/肥胖的干预措施在设计时应考虑居住地因素。
