Limited data exist related to low birth weight (LBW) incidence and risk factors in Western China. This paper aims to assess LBW and its relationship with antenatal care (ANC) in the poor counties of Western China. A community-based study in rural Western China was conducted in 2011. A kernel distribution was used to estimate the adjusted LBW incidence, and associations between LBW and socio-demographic or maternal factors were examined using multilevel logistic regression. Among 8,964 participants, 65.7% were weighed at birth. Crude LBW incidence was 6.6% and the adjusted rate was 9.3%. The study revealed that risk factors of LBW are being female, raised within a minority group, and with a family income below the national poverty line. For maternal risk factors, LBW was positively associated with not attending at least five or eight ANC visits, not receiving any ANC during the first trimester, and not having access to assess certain ANC content (weight, blood pressure, blood test, urine test, B-scan ultrasound, and folic acid supplement). There is urgent need to promote quality ANC in poor and rural areas of Western China and to prioritize vulnerable women and children who will benefit from quality ANC.
在中国西部，有关低出生体重（LBW）发生率和危险因素的资料有限。本文旨在评估中国西部贫困县的 LBW 及其与产前保健（ANC）的关系。2011 年在中国西部农村进行了一项基于社区的研究。使用核密度估计来估计调整后的 LBW 发生率，并使用多水平逻辑回归检查 LBW 与社会人口统计学或产妇因素之间的关系。在 8964 名参与者中，有 65.7%在出生时称重。粗 LBW 发生率为 6.6%，调整后的发生率为 9.3%。研究表明，LBW 的危险因素是女性、少数民族、家庭收入低于国家贫困线。对于产妇危险因素，LBW 与至少接受五次或八次 ANC 检查、在孕早期未接受任何 ANC 检查以及无法评估某些 ANC 内容（体重、血压、血液检查、尿液检查、B 超检查和叶酸补充）呈正相关。迫切需要在西部贫困和农村地区推广优质 ANC，并优先考虑弱势妇女和儿童，他们将从优质 ANC 中受益。
