This study verified the night blindness prevalence, the first manifestation of this deficiency, and its association with socioeconomic, nutritionals and obstetric variables of 92 pregnant who were assisted on a health municipal center in Diamantina, Vale do Jequitinhonha. Data was collected through a model interview recommended by WHO (1996) to diagnose night blindness. The statistic analysis used Fisher exact test and Wilcoxon test. The results showed a higher prevalence of night blindness at Diamantina districts and neighbor cities (13.04%). No significant association was found between night blindness and socioeconomic and obstetric variables (p>0.05). It was observed a low vitamin A levels by pregnant with night blindness (4.4). This found shows the necessity of more investigations on vitamin A deficiency in order to help prevent, diagnose and combat this issue.
本研究核实了夜盲症的患病率（这种营养素缺乏的首要表现），以及在热基蒂尼奥尼亚河谷迪亚曼蒂纳市一家市级保健中心接受护理的92名孕妇的夜盲症患病率与其社会经济、营养和产科变量之间的关联。通过世界卫生组织（1996年）推荐的用于诊断夜盲症的标准访谈收集数据。统计分析采用费舍尔精确检验和威尔科克森检验。结果显示，迪亚曼蒂纳地区及周边城市的夜盲症患病率较高（13.04%）。未发现夜盲症与社会经济和产科变量之间存在显著关联（p>0.05）。观察到患夜盲症的孕妇维生素A水平较低（4.4）。这一发现表明有必要对维生素A缺乏症开展更多调查，以帮助预防、诊断和应对这一问题。
