Research finds that people from lower socioeconomic backgrounds are more likely to experience complications during pregnancy, such as gestational diabetes and high blood pressure. But what's driving these issues? The study used a unique approach to investigate the relationship between socioeconomic status and adverse pregnancy outcomes. It found that higher education levels can actually increase the risk of certain pregnancy problems, like gestational diabetes and pre-eclampsia, likely because educated women are more likely to be overweight or have lower vitamin D levels. In contrast, behaviors like smoking and drinking can also contribute to these issues, but in different ways. Overall, the study suggests that socioeconomic disadvantage has a lasting impact on pregnancy outcomes, often through subtle factors like education level and lifestyle choices.
