Partner change and perinatal outcomes: a systematic review
1Epidemiology Branch, National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA.
Changing partners may reduce birth defect recurrence but the impact on pre-eclampsia, preterm birth, and low birth weight remains unclear. More research is needed on partner change and pregnancy outcomes.
Area of Science:
- Epidemiology
- Reproductive Health
- Perinatal Outcomes
Background:
- Partner change is hypothesized to influence perinatal outcomes in subsequent pregnancies.
- Existing epidemiological studies suggest a potential link between paternity change and various pregnancy complications.
Purpose of the Study:
- To systematically review the scientific literature on the association between partner change and perinatal outcomes.
- To synthesize evidence regarding pre-eclampsia, preterm birth, low birth weight, and birth defects in relation to partner change.
Main Methods:
- A systematic literature search was conducted in MEDLINE (1966-2005) using keywords related to paternity, partner change, and perinatal outcomes.
- Included studies examined associations between partner change and pre-eclampsia, birth defects, preterm birth, and low birth weight.
Main Results:
- Partner change was linked to increased pre-eclampsia risk in unadjusted analyses, but results were inconsistent after controlling for birth interval.
- Evidence on partner change and preterm birth or low birth weight was inconclusive.
- Partner change was associated with a significantly reduced risk of recurrent birth defects.
Conclusions:
- Partner change appears to reduce the risk of recurrent birth defects in subsequent pregnancies.
- The effect of partner change on pre-eclampsia, preterm birth, and low birth weight requires further investigation.
- Caution is advised regarding the control of birth interval in studies examining partner change and pre-eclampsia.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
