食土癖-经常和故意食用土壤-在撒哈拉以南非洲的孕妇中很普遍。我们在坦桑尼亚971名人类免疫缺陷病毒（HIV）阳性孕妇中研究了食土行为与贫血和蠕虫感染的关系。大约29%的孕妇经常食用土壤。职业、婚姻状况和胎龄与食土行为有关。蛔虫感染与食土癖的患病率相关（校正患病率比1.81：95%置信区间[CI] = 1.37-2.40）;然而，钩虫、鞭虫和粪类圆线虫没有显示出相关性。提示缺铁的贫血和红细胞特征与基线时的食土行为密切相关。在纵向分析中，我们发现有证据表明，土壤消耗可能与贫血风险增加（校正相对风险1.16：95%，CI = 0.98-1.36）和血红蛋白浓度降低（校正平均差异-3.8 g/L; 95% CI [-7.3 -0.4]）相关。应告知孕妇食用土壤的潜在风险。
Geophagy the regular and deliberate consumption of soil, is prevalent among pregnant women in sub-Saharan Africa. We examined the associations of geophagy with anemia and helminth infection among, 971 human immunodeficiency virus (HIV)-positive pregnant women in Tanzania. About 29% of pregnant women regularly consumed soil. Occupation, marital status, and gestational age were associated with geophagy. Ascaris himbricoides infection Was associated with the prevalence of geophagy (adjusted-prevalence ratio 1.81:95% confidence interval [CI] = 1.37-2.40); however, hookworm, Trichuris trichiura, and Strongyloides stercoralis showed no association. Anemia and red blood cell characteristics suggestive of iron deficiency were strongly correlated with geophagy at baseline. In longitudinal analyses, We found evidence suggesting that soil consumption may be associated with an increased risk of anemia (adjusted-relative risk 1.16: 95%, CI = 0.98-1.36) and a lower hemoglobin concentration (adjusted-mean difference -3.8 g/L; 95% CI [-7.3 -0.4]). pregnant women should be informed about the potential risks associated with soil consumption.
