目的·了解妊娠期女性妊娠压力水平、孕前保健行为及应对方式，分析妊娠压力的影响因素，为妊娠期女性孕期健康管理提供参考。方法·纳入2022年4月—8月在遵义医科大学附属医院产科门诊就诊的265名妊娠期妇女为研究对象，采用一般资料情况问卷、孕前保健行为问卷、妊娠压力量表、简易应对方式问卷，取得患者同意后，调查妊娠期女性妊娠压力、孕前保健行为及应对方式，分析其之间的相关性。结果·妊娠期女性妊娠压力总平均分为（1.05±0.41）分。多元线性回归分析结果显示，年龄、妊娠次数、先兆流产史、对胎儿性别期待、参加孕妇学校或观看相关手册是妊娠压力的主要影响因素（P<0.05）。孕前保健行为得分为（10.09±2.63）分，具备高等、中等、低等水平的妊娠期孕前保健行为人数占比分别为17.36%、54.34%和28.30%。妊娠期女性应对方式总分为（27.22±9.68）分，其中积极应对维度得分为（17.79±9.84）分，消极应对维度得分为（9.42±7.39）分。Pearson相关分析显示，妊娠压力与孕前保健行为呈负相关（r=-0.313，P<0.01），妊娠压力与应对方式呈负相关（r=-0.163，P<0.01），孕前保健行为与应对方式呈正相关（r=0.220，P<0.01）。结论·妊娠期女性妊娠压力处于中度水平，孕前保健行为较少，护理人员应大力加强孕前健康知识普及和保健指导，让育龄期女性孕前主动、积极地学习妊娠相关保健知识和应对技巧，最大程度地减少或避免不良母婴妊娠结局，优化母婴保健策略和提升健康水平。

Objective ·To assess the levels of pregnancy-related stress, pre-pregnancy health care behaviors, and coping styles among pregnant women,analyze the influencing factors of pregnancy stress and provide insights for the management of pregnancy health in expectant mothers. Methods ·A total of 265 pregnant women receiving treatment at the Obstetrics Clinic of the Affiliated Hospital of Zunyi Medical University from April to August 2022 were included as participants. General information questionnaires, pre-pregnancy health care behavior questionnaires, pregnancy stress scales and simple coping style questionnaires were utilized for data collection. After obtaining the consent of the patients, assessments on pregnancy stress levels, pre-pregnancy health care behaviors, and coping styles were conducted. Results ·The overall average score for pregnancy stress among pregnant women was 1.05±0.41. Multiple linear regression analysis revealed that age, number of pregnancies, history of threatened abortion, fetal gender expectations, attending prenatal education classes or reviewing relevant manuals significantly influenced pregnancy-related stresses (P<0.05). The score of pre-pregnancy health care behavior was 10.09±2.63 with proportions indicating high-level, medium-level, and low-level adherence at 17.36%, 54.34%,and 28.30%. In pregnant women, the total score for coping styles was 27.22±9.68, with a positive coping dimension score of 17.79±9.84 and a negative coping dimension score of 9.42±7.39. Pearson correlation analyses demonstrated a negative association between pregnancy-related stresses and pre-pregnancy health care behaviors (r=-0.313, P<0.01), and a negative correlation between pregnancy-related stresses and coping styles (r=-0.163, P<0.01), while a positive relationship existed between pre-pregnancy health care behaviors and coping styles (r=0.220, P<0.01). Conclusion ·Pregnant women experience moderate levels of pressure during their pregnancies and have suboptimal engagement in preconceptional healthcare practices. Nursing staff should intensify efforts towards disseminating knowledge on preconceptional healthcare practices, thereby empowering women of childbearing age to actively acquire pertinent reproductive-health knowledge prior to conception so that minimizing adverse maternal-infant outcomes, optimizing maternal-infant healthcare strategies, and enhancing overall well-being can be achieved through these measures.
