Background: Pregnancy-induced hypertension is a common complication in obstetrics and an important cause of maternal death. We explored the correlations among stress, family function and coping mode in women with pregnancy-induced hypertension syndrome.Methods: A total of 58 pregnant women with pregnancy-induced hypertension syndrome were included in the study. The perceived stress scale (PSS), family assessment device (FAD), and medical coping modes questionnaire (MCMQ) were used to assess stress level, family function, and coping mode, respectively. Results:The PSS score was 28 (interquartile range: 20-43). The total FAD score was 128.1±27.1. The subscale scores were problem-solving, affective responsiveness, communication, roles, behavior control, affective involvement, and general function, in order of decreasing score. Significant correlations were noted between PSS score and total FAD score, affective responsiveness, problem-solving, communication, roles, affective involvement, and behavior control (all P<0.05). PSS score was significantly correlated with "Escape" (P=0.016) and "Yield" (P<0.001) in the MCMQ. Single-factor analysis showed that education level, average household income, and FAD total score were significantly different in those with a low or high PSS score.Logistic regression indicated the FAD total score as an independent factor for the PSS score.Conclusions: Women with pregnancy-induced hypertension syndrome with a high PSS score tended to adopt the "Escape" and "Yield" coping modes. Family function integrity is essential for reducing PSS scores.
