The present study was undertaken to assess the impact of drought on the nutritional status of pre-school children aged 0-5 years from a rural population in a desert area facing drought conditions very frequently.
The sampling design for assessment was the three-stage sampling technique.
The study was carried out in 24 villages belonging to six tehsils (sub-units of district) of Jodhpur District, a drought-affected desert district of western Rajasthan, during a drought in 2003.
A total of 914 children were examined at household level, with nutritional status assessed by anthropometry, dietary intake and clinical signs of nutritional deficiency.
The results revealed growth retardation. Stunting (malnutrition of long duration) was observed in 53% of children and underweight in 60%. Wasting, an indicator of short-duration malnutrition, was present in 28% of children. The extent of malnutrition was significantly higher in girls than boys (P<0.05). Vitamin A and B complex deficiencies were found in 0.7 and 3.0% of children, respectively. Prevalence of marasmus (protein-energy malnutrition, PEM) was 1.7% (2.3% in boys and 1.1% in girls). Overall deficits in mean energy and protein intakes were very high (76 and 54%, respectively). Comparison of the present drought results with earlier studies in desert normal and desert drought conditions showed higher prevalence of PEM and higher dietary energy and protein deficiencies.
The prevalence of wasting was high, greater than the cut-off point of 15% stated by the World Health Organization to indicate that the severity of malnutrition is critical. PEM, vitamin A and B complex deficiencies and anaemia, along with dietary deficits of energy and protein, were observed to be higher than in non-desert areas. This may be due to the harsh environmental conditions in desert areas where drought occurs quite frequently and adversely affects the economy, largely by eroding the coping capacity and economic potential of the people as a result of heavy livestock losses and reduced harvests, leading to increased poverty and poor food intake of the inhabitants. Due to inadequate consumption of daily food the children were suffering from wasting and PEM. Efforts should be made to incorporate measures, such as ensuring the supply of adequate energy and protein to all age groups and especially pre-school children, into ongoing nutrition programmes in order to improve the food security of local inhabitants in this area.
本研究旨在评估干旱对来自沙漠地区农村、经常面临干旱的0至5岁学龄前儿童营养状况的影响。
评估采用三阶段抽样技术。
该研究于2003年干旱期间,在拉贾斯坦邦西部受干旱影响的沙漠地区焦特布尔县六个乡(区的下属单位)所属的24个村庄开展。
共对914名儿童进行了家庭层面的检查,通过人体测量、饮食摄入和营养缺乏的临床体征评估营养状况。
结果显示生长发育迟缓。53%的儿童存在发育迟缓(长期营养不良),60%的儿童体重不足。消瘦是短期营养不良的指标,28%的儿童存在消瘦情况。女孩的营养不良程度显著高于男孩(P<0.05)。分别有0.7%和3.0%的儿童存在维生素A和B族维生素缺乏。消瘦型营养不良(蛋白质 - 能量营养不良,PEM)的患病率为1.7%(男孩为2.3%,女孩为1.1%)。平均能量和蛋白质摄入量的总体不足非常高(分别为76%和54%)。将当前干旱情况下的结果与沙漠正常和沙漠干旱条件下的早期研究进行比较,发现PEM的患病率更高,饮食能量和蛋白质缺乏情况更严重。
消瘦的患病率很高,高于世界卫生组织规定的表明营养不良严重程度危急的15%的临界点。观察到PEM、维生素A和B族维生素缺乏以及贫血,以及饮食中能量和蛋白质的缺乏情况均高于非沙漠地区。这可能是由于沙漠地区恶劣的环境条件,那里干旱频繁发生,对经济产生不利影响,主要是通过大量牲畜损失和收成减少削弱了人们的应对能力和经济潜力,导致贫困加剧和居民食物摄入量减少。由于日常食物消费不足,儿童患有消瘦和PEM。应努力将确保向所有年龄组,特别是学龄前儿童提供充足能量和蛋白质等措施纳入正在进行的营养计划,以改善该地区当地居民的粮食安全。
