Crone MR, et al. - Researchers focused on recognizing several groups of pregnant women based on their behavioral, psychosocial and socio-economic features and their pregnancy outcomes. They categorized (n = 2,455) 12-week pregnant women into four latent classes. Healthy higher-educated pregnant women who did not smoke constituted 2 classes: one group including multigravida women and one comprising primigravida women, also characterized by less pregnancy-specific knowledge and more pregnancy-associated stress. Two less healthy groups including the remaining women were also defined. One group characterized by frequent smoking cessation, less healthy eating, less physical activity and comparable stress levels as the healthy higher-educated groups, and the last one, comprising most smokers, demonstrated the highest scores on psychosocial and pregnancy-related stress and the most adverse socio-economic circumstances. The risk of adverse maternal outcomes, especially of developing diabetes during pregnancy, was reported in this group. Findings highlight the necessity of a comprehensive and integrated strategy to improve results in pregnancies with a combination of adverse health, psychosocial, and socio-economic conditions.
