A survey was carried out in Guyana to determine the prevalence and the etiology of the nutritional anemias among both sexes, in various age groups, and in pregnant and lactating women. The sample consisted of 590 subjects drawn from 103 households selected by multistage cluster sampling. Anthropometric and hematological measurements and stool investigations for intestinal parasites were carried out in each subject. Socioeconomic and other demographic data were obtained for each household. High prevalences of anemia, although of a relatively mild degree, were found among all age groups especially among pregnant and lactating women. The major factors related to Hb levels were found to be inadequate consumption of food rich in the erythropoietic nutrients, iron deficiency, age, sex, pregnancy, household income, and percentage of household income spent on food. A number of socioeconomic and other demographic variables were associated with anemia. More anemia was found in urban than in rural areas.
在圭亚那进行了一项调查，以确定不同性别、不同年龄组以及孕妇和哺乳期妇女中营养性贫血的患病率和病因。样本由通过多阶段整群抽样从103户家庭中抽取的590名受试者组成。对每个受试者进行了人体测量、血液学测量以及肠道寄生虫粪便检查。获取了每个家庭的社会经济和其他人口数据。在所有年龄组中，尤其是孕妇和哺乳期妇女中，发现贫血患病率很高，尽管程度相对较轻。发现与血红蛋白水平相关的主要因素是富含促红细胞生成营养素的食物摄入不足、缺铁、年龄、性别、怀孕、家庭收入以及家庭收入中用于食物的百分比。一些社会经济和其他人口变量与贫血有关。城市地区的贫血患者比农村地区更多。
