To examine dietary pattern and nutritional status of adolescent college girls of Dhaka, Bangladesh with a particular focus on the prevalence of anaemia and appropriate knowledge about it among them.
A cross sectional study was conducted. Sixty-five adolescent girls aged 15-19 years were selected randomly from Home Economics college of Dhaka. A 7-day food frequency questionnaire was used to investigate the dietary pattern. Nutrient intake of the participants was assessed by 24h recall method.
Habitual dietary pattern indicated poor consumption of milk, liver and leafy vegetables. Food intake data revealed a deficit of 473 kcal/day in energy. Mean intake of carbohydrate and fat were lower than RDA; while protein, iron, vitamin A and vitamin C intakes were much higher. Anthropometric data indicated that 63% of the girls were stunted (height-for-age < 95% of NCHS reference values) and 45% were underweight (weight-for-age < 75% of NCHS reference values). The prevalence of anaemia (Hb < 12 g/dl) among the participants was 23%. About 17% had low serum iron (< 40 microg/dl), 23% showed evidence of iron-deficient erythropoiesis (Transferrin Saturation < 15%) and only 8% had vitamin C deficiency (< 0.29 mg/dl). About 65% of the participants had correct knowledge about the causes of anaemia; while 72.3% and 80% respectively, knew about the prevention and treatment of anaemia. Surprisingly, 73.8% of the participants were not aware about the sources of iron-rich foods.
Results indicate an overall poor nutritional status of the urban adolescent college girls in Bangladesh and need for appropriate nutrition interventions to overcome the problem.
研究孟加拉国达卡地区青春期女大学生的饮食模式和营养状况，特别关注贫血患病率以及她们对贫血的相关知识掌握情况。
开展一项横断面研究。从达卡家政学院随机选取65名15 - 19岁的青春期女孩。采用7天食物频率问卷调查饮食模式。通过24小时回顾法评估参与者的营养素摄入量。
习惯性饮食模式显示牛奶、肝脏和绿叶蔬菜的摄入量较低。食物摄入数据表明能量每天 deficit 473千卡。碳水化合物和脂肪的平均摄入量低于推荐膳食摄入量；而蛋白质、铁、维生素A和维生素C的摄入量则高得多。人体测量数据表明，63%的女孩发育迟缓（身高年龄低于美国国家卫生统计中心参考值的95%），45%的女孩体重不足（体重年龄低于美国国家卫生统计中心参考值的75%）。参与者中贫血（血红蛋白<12克/分升）的患病率为23%。约17%的人血清铁水平低（<40微克/分升），23%的人有缺铁性红细胞生成的迹象（转铁蛋白饱和度<15%），只有8%的人维生素C缺乏（<0.29毫克/分升）。约65%的参与者对贫血原因有正确认识；而分别有72.3%和80%的人知道贫血的预防和治疗方法。令人惊讶的是，73.8%的参与者不知道富含铁的食物来源。
结果表明孟加拉国城市青春期女大学生的总体营养状况较差，需要采取适当的营养干预措施来解决这一问题。
