几项研究表明，产前锌缺乏（ZD）易导致多种妊娠并发症。然而，关于产前ZD的决定因素的科学证据是缺乏和不确定的。本研究的目的是评估埃塞俄比亚南部Sidama地区产前ZD的患病率和决定因素。2011年1月和2月在Sidama区进行了一项以社区为基础的横断面研究。该研究随机选择了700名孕妇。使用结构化问卷收集ZD潜在决定因素的数据。采用原子吸收光谱法测定血清锌浓度。采用logistic回归和线性回归进行统计分析。血清锌平均浓度为52.4 (+/-9.9)μg/dl （95% CI: 51.6 ~ 53.1 μg/dl）。约53.0% （95% CI: 49.3 ~ 56.7%）的受试者缺锌。大多数解释的血清锌变异是由于饮食因素，如家庭粮食不安全水平、饮食多样性和动物源食品的消费。玉米主食类妇女患ZD的风险是Enset主食类妇女的1.65倍（95% CI: 1.02-2.67）。与15-24岁孕妇相比，25-34岁和35-49岁孕妇患ZD的风险分别高出1.57倍（95% CI: 1.04-2.34）和2.18倍（95% CI: 1.25-3.63）。没有自我收入的女性的风险比她们的同行高出1.74 （95% CI: 1.11-2.74）倍。母亲受教育程度与锌含量呈正相关。大多年生儿童缺锌的可能性是无年生儿童的1.74倍（95% CI: 1.09-3.23）。咖啡摄入频率与血清锌水平呈负相关。血清锌与血红蛋白浓度呈正相关。海拔高度、补铁史、产妇工作量、身体获得保健服务、产前保健和营养教育与锌状况无关。ZD是该地区令人关注的公共卫生问题。必须通过短期、中期和长期战略相结合来解决这一问题。这包括使用以家庭为基础的减少植酸食品加工技术、以农业为基础的方法和促进生计的战略。
Several studies witnessed that prenatal zinc deficiency (ZD) predisposes to diverse pregnancy complications. However, scientific evidences on the determinants of prenatal ZD are scanty and inconclusive. The purpose of the present study was to assess the prevalence and determinants of prenatal ZD in Sidama zone, Southern Ethiopia. A community based, cross-sectional study was conducted in Sidama zone in January and February 2011. Randomly selected 700 pregnant women were included in the study. Data on potential determinants of ZD were gathered using a structured questionnaire. Serum zinc concentration was measured using Atomic Absorption Spectrometry. Statistical analysis was done using logistic regression and linear regression. The mean serum zinc concentration was 52.4 (+/-9.9) μg/dl (95% CI: 51.6-53.1 μg/dl). About 53.0% (95% CI: 49.3-56.7%) of the subjects were zinc deficient. The majority of the explained variability of serum zinc was due to dietary factors like household food insecurity level, dietary diversity and consumption of animal source foods. The risk of ZD was 1.65 (95% CI: 1.02-2.67) times higher among women from maize staple diet category compared to Enset staple diet category. Compared to pregnant women aged 15-24 years, those aged 25-34 and 35-49 years had 1.57 (95% CI: 1.04-2.34) and 2.18 (95% CI: 1.25-3.63) times higher risk of ZD, respectively. Women devoid of self income had 1.74 (95% CI: 1.11-2.74) time increased risk than their counterparts. Maternal education was positively associated to zinc status. Grand multiparas were 1.74 (95% CI: 1.09-3.23) times more likely to be zinc deficient than nulliparas. Frequency of coffee intake was negatively association to serum zinc level. Positive association was noted between serum zinc and hemoglobin concentrations. Altitude, history of iron supplementation, maternal workload, physical access to health service, antenatal care and nutrition education were not associated to zinc status. ZD is of public health concern in the area. The problem must be combated through a combination of short, medium and long-term strategies. This includes the use of household based phytate reduction food processing techniques, agricultural based approaches and livelihood promotion strategies.
