Our purpose was to assess whether an intervention in the education of the mother and the support person involves a change in health-related behavior and use of health facilities.
A randomized, controlled trial was conducted in four cities of Latin America on pregnant women at risk. Half of them (n = 1115) received a home intervention of four to six visits dealing with psychosocial support and education about health-related habits, alarm signs, hospital facilities, antismoking and antialcohol programs, and a reinforcement of adequate health services utilization for the pregnant woman and a support person. The control group (n = 1120) received routine prenatal care.
The distribution of risk factors and demographic, obstetric, and psychologic characteristics at baseline was similar in both groups. Women in the intervention group showed a statistically significant better knowledge of seven of the nine alarm signs considered and of two of the three labor-onset signs required. No differences between groups were observed in improvement on diet, cigarette and alcohol consumption, maternal physical strain, lactation at 40 days postpartum, and utilization of health facilities.
An intervention of psychosocial support and health education during pregnancy failed to show any benefit on perinatal outcome, health-related behavior, or utilization of health facilities.
我们的目的是评估对母亲及陪伴人员进行教育干预是否会改变与健康相关的行为及卫生设施的使用情况。
在拉丁美洲的四个城市对有风险的孕妇进行了一项随机对照试验。其中一半孕妇（n = 1115）接受了为期四至六次的家庭干预，内容包括心理社会支持以及有关健康相关习惯、警示信号、医院设施、戒烟和戒酒计划的教育，同时加强孕妇及陪伴人员对适当卫生服务的利用。对照组（n = 1120）接受常规产前护理。
两组在基线时的危险因素分布以及人口统计学、产科和心理特征相似。干预组的女性对所考虑的九个警示信号中的七个以及三个分娩开始信号中的两个表现出统计学上显著更好的认知。在饮食、吸烟和饮酒、产妇身体劳损、产后40天的哺乳情况以及卫生设施的使用方面，两组之间未观察到差异。
孕期的心理社会支持和健康教育干预未能对围产期结局、与健康相关的行为或卫生设施的使用显示出任何益处。
