Abstract：
BACKGROUND: Infant survival is an important factor in any community\'s health. Low birth weight affects babies not only during their infancy but also has long-term consequences for their health as adults. Unfortunately, Sub-Saharan Africa as a region is still dealing with the burden of Low birth weight (LBW), and Tanzania as a part of this region is no exception. So this study aimed to determine the Magnitude of Low Birth Weight and Its Associated Maternal Factors among Women of Reproductive Age who gave birth to live babies.
METHODS: The study used analytical cross-sectional study design to analyze secondary data from the Tanzania Demographic and Health Survey and Malaria Indicators Survey 2015-2016. A total of 4,644 women of reproductive age who gave birth to live babies within five years preceding the survey were included in the study. Both bivariate and multivariable logistics regression analyses were used to assess maternal factors associated with low birth weight.
RESULTS: The prevalence of LBW was 262(6.2%). After adjusting for confounders, the maternal factors associated with LBW were Age group of a pregnant woman [Less than 20 years (aOR = 1.907 CI = 1.134-3.205) in reference to those aged more than 34years], Number of ANC visits made [Inadequate visits (aOR = 1.612 CI = 1.266-2.05)], parity [para 2-4 (aOR = 0.609 CI = 0.453-0.818), para 5+ (aOR = 0.612 CI = 0.397-0.944)] and area of residence [Unguja (aOR = 1.981 CI = 1.367-2.87).
CONCLUSIONS: The prevalence of low birth weight in Tanzania remains high. Women\'s age, parity, number of Antenatal care visits (ANC), and area of residence were found to be maternal factors associated with LBW. Thus, early prenatal diagnosis of risk factors for low birth weight in high-risk pregnant women may help to reduce the LBW burden in Tanzania and its detrimental effects.

摘要：
背景：婴儿生存是任何社区健康的重要因素。低出生体重不仅会影响婴儿的婴儿期，还会对他们成年后的健康产生长期影响。不幸的是,撒哈拉以南非洲作为一个区域仍在处理低出生体重（LBW）的负担，坦桑尼亚作为该地区的一部分也不例外。因此，本研究旨在确定生育活婴的育龄妇女的低出生体重及其相关母体因素。
方法：该研究使用分析性横断面研究设计来分析来自2015-2016年坦桑尼亚人口与健康调查和疟疾指标调查的次要数据。该研究包括在调查前五年内生下活婴的4,644名育龄妇女。使用双变量和多变量物流回归分析来评估与低出生体重相关的母体因素。
结果：LBW的患病率为262（6.2％）。在调整了混杂因素后，与LBW相关的母亲因素是孕妇的年龄组[小于20岁（aOR=1.907CI=1.134-3.205），ANC访问次数[访问不足（aOR=1.612CI=1.266-2.05）]，奇偶校验[第2-4段(AOR=0.609CI=0.453-0.818)，第5段+（aOR=0.612CI=0.397-0.944）]和居住地[Unguja（aOR=1.981CI=1.367-2.87）。
结论：坦桑尼亚低出生体重的患病率仍然很高。女人的年龄,奇偶校验，产前护理就诊次数(ANC)，和居住地被发现是与LBW相关的母体因素。因此，对高危孕妇低出生体重的危险因素进行早期产前诊断可能有助于减轻坦桑尼亚的LBW负担及其不利影响.
