Background: Epidemiologic studies have demonstrated that ambient concentrations of particulate matter < 2.5 μm (PM) are associated with reduced fecundability, the per cycle probability of conception. The specific constituents driving this association are unknown.

Background: Weight bias is a global health challenge and community members are endorsed as the most common source of weight bias. The nature of weight biases specifically against preconception, pregnant, and postpartum (PPP) women from the perspective of community members is not known, especially in terms of cross-cultural trends. We investigated the magnitude of explicit and implicit weight bias and profiles of characteristics associated with harbouring weight bias.

This study aimed to assess the strengths, limitations, opportunities, and threats presented by diabetes-in-pregnancy. We review the improvements in maternal and fetal mortality since the advent of insulin therapy, evaluate current health challenges, and identify opportunities for preventing increased mortality due to diabetes-in-pregnancy. Prior to 1922, women with type 1 diabetes mellitus (T1DM) of childbearing age were discouraged from becoming pregnant as the maternal and fetal/neonatal mortality rates were extremely high.

Background: Direct evidence linking ambient temperature to human fecundity is sparse. We aimed to evaluate the potential impact of ambient temperature on time to pregnancy (TTP) and identify the optimal temperature range for initiating conception attempts.
Methods: Our analysis included 576 927 couples from the Chinese National Free Preconception Health Examination Project (NFPHEP) in Yunnan Province, with a one-year follow-up post-enrollment.

Introduction: The global prevalence of people living with overweight has tripled since 1975 and more than 40% of Danish women enter pregnancy being overweight. With the increasing rates of obesity observed in children, adolescents and adults, there is an urgent need for preventive measures. Risk factors for childhood obesity include maternal overweight or obesity before conception and excessive weight gain during pregnancy.
