Low birthweight and preterm birth are risk factors for infant mortality and persistent problems. This study uses representative data to assess whether distinct latent profiles of co-occurring medical and psychosocial factors have implications for preterm birth and low birthweight.
Data are from the Pregnancy Risk Assessment Monitoring System, a cross-sectional survey constituting representative data on pregnancies from 2012 to 2013. Latent class analysis derived classes of pregnant women potentially at risk for low birthweight and/or preterm birth.
Latent class analysis identified five homogenous profiles of interrelated psychosocial and medical factors. Risk was greatest for the profile marked by high rates of medical factors, followed by a high risk for a profile marked by a combination of very low income and psychosocial factors. Two profiles involving low income and very low income also indicated greater risk for adverse birth outcomes related to socioeconomic status.
More attention should be paid to screening for and addressing psychosocial risk in concert with prenatal care. Women who show high-risk profiles can be monitored and supported by an interdisciplinary care team, when warranted.
低出生体重和早产是婴儿死亡和持续性问题的风险因素。本研究使用代表性数据评估同时存在的医学和心理社会因素的不同潜在分布是否对早产和低出生体重有影响。
数据来自妊娠风险评估监测系统，这是一项横断面调查，构成了 2012 年至 2013 年妊娠的代表性数据。潜在类别分析得出了可能面临低出生体重和/或早产风险的孕妇的同质类别。
潜在类别分析确定了五个相互关联的心理社会和医学因素的同质分布。具有高比例医学因素的分布风险最大，其次是具有极低收入和心理社会因素组合的分布风险较高。涉及低收入和非常低收入的两个分布也表明，与社会经济地位相关的不良出生结局风险更高。
应该更加关注与产前保健同时筛查和解决心理社会风险。有高风险特征的妇女在必要时可以由跨学科护理团队进行监测和支持。
