Prenatal screening

Recognising that screening programs can cause anxiety in pregnant women as they wait for their test results, researchers have studied how disclosing aminocentesis or chorionic villous sampling (CVS) results on a fixed date versus a variable date (i.e. "when available") affects maternal anxiety. Systematic review of the relevant articles found no conclusive evidence to support issuing aminocentesis results as soon as they become available (in comparison to issuing results on a pre-defined fixed date). Further studies evaluating the effect of different strategies for disclosing CSV results on maternal anxiety are needed.

Excess weight retention after pregnancy is a predictor of long-term obesity[cite]. Though diet and exercise and diet alone help women lose weight post childbirth, losing weight through a combination diet and exercise may be preferable as this can improve maternal cardiorespiratory fitness and preserves fat-free mass.
