In populations with a history of conflict, early identification of pregnant women who are at risk of adverse pregnancy outcomes is challenging, especially if sonography is not available. We evaluated the performance of symphysis-fundal height (SFH) for identification of high-risk pregnancies and investigated if food security and diet quality, clinical biomarkers, and stress were associated with SFH and two known indicators of maternal-fetal well-being, sonography-estimated fetal weight and amniotic fluid index (AFI). For this cross-sectional study, 61 women with high-risk pregnancies were recruited after referral to the obstetrics and gynecology unit at San José Hospital in Popayán, Colombia. Multiple stepwise linear and ordered logistic regressions were used to identify associations of SFH, sonography-estimated fetal weight and AFI classification with history of displacement, food insecurity, post-traumatic stress symptoms as well as biopsychosocial risk evaluated through the Colombian risk scale. History of displacement was associated with lower SFH Z-scores, but higher hemoglobin, taking iron supplements and a higher diastolic blood pressure were associated with higher SFH Z-scores. SFH was also associated with AFI but not with sonography-estimated fetal weight. Stress indicators were associated with a higher AFI. In contrast family support, an element of the Colombian biopsychosocial risk assessment, was associated with a higher sonography-estimated fetal weight, whereas more hours of sleep/day were associated with lower sonography-estimated fetal weight. SFH was not only associated with biological factors known to affect maternal/fetal health but also with history of displacement, thus validating its use in conflict areas for pregnancy assessment. Associations of biopsychosocial stressors with maternal-fetal outcomes highlight the need for a systematic assessment of stress in pregnant women from conflict zones.
在有冲突历史的人群中,早期识别有不良妊娠结局风险的孕妇具有挑战性,尤其是在无法进行超声检查的情况下。我们评估了耻骨联合上缘高度(SFH)用于识别高危妊娠的性能,并调查了粮食安全和饮食质量、临床生物标志物以及压力是否与SFH以及两个已知的母婴健康指标(超声估计胎儿体重和羊水指数(AFI))相关。在这项横断面研究中,61名高危妊娠妇女在被转诊至哥伦比亚波帕扬圣何塞医院妇产科后被招募。采用多步线性和有序逻辑回归来确定SFH、超声估计胎儿体重和AFI分类与流离失所史、粮食不安全、创伤后应激症状以及通过哥伦比亚风险量表评估的生物心理社会风险之间的关联。流离失所史与较低的SFH Z评分相关,但较高的血红蛋白、服用铁补充剂和较高的舒张压与较高的SFH Z评分相关。SFH也与AFI相关,但与超声估计胎儿体重无关。压力指标与较高的AFI相关。相比之下,哥伦比亚生物心理社会风险评估要素之一的家庭支持与较高的超声估计胎儿体重相关,而每天睡眠时间越长与较低的超声估计胎儿体重相关。SFH不仅与已知影响母婴健康的生物学因素相关,还与流离失所史相关,从而验证了其在冲突地区用于妊娠评估的用途。生物心理社会应激源与母婴结局之间的关联凸显了对冲突地区孕妇压力进行系统评估的必要性。
