Insights
Planned pregnancies significantly reduce the risk of orofacial clefts in offspring. Unplanned pregnancies combined with first-trimester smoking further elevate this risk, highlighting the importance of preconception planning.
Area of Science:
- Reproductive Health
- Pediatric Health
- Epidemiology
Background:
- Orofacial clefts are common birth defects with multifactorial causes.
- Pregnancy planning is a key factor in maternal and child health outcomes.
- Understanding risk factors for orofacial clefts is crucial for prevention strategies.
Purpose of the Study:
- To investigate the association between pregnancy planning and the occurrence of orofacial clefts.
- To identify specific risk factors contributing to orofacial cleft development.
Main Methods:
- A case-control study was conducted in the United Kingdom.
- 191 infants with nonsyndromic orofacial clefts and 247 controls were analyzed.
- Data were collected between 1997 and 2000.
Main Results:
- A statistically significant inverse association was found between planned pregnancies and orofacial clefts (OR = 0.51, 95% CI = 0.33-0.79).
- Unplanned pregnancies coupled with first-trimester smoking increased the risk of orofacial clefts nearly threefold compared to planned, non-smoking pregnancies (OR = 2.92, 95% CI = 1.50-5.65).
Conclusions:
- Planned pregnancies are associated with a reduced risk of orofacial clefts.
- Reducing unplanned pregnancies is essential for orofacial cleft prevention.
- Preconception advice and interventions should be widely disseminated to improve pregnancy planning.
Objective:
To investigate the association between pregnancy planning and orofacial clefts in the United Kingdom.
Design:
Case-control study.
Setting:
Scotland and the Manchester and Merseyside regions of England.
Participants:
One hundred and ninety-one children born with nonsyndromic orofacial cleft, 1997 to 2000, and 247 controls.
Main Outcome Measure:
Cleft lip with and without cleft palate, and cleft palate.
Results:
There was an inverse association between planning for pregnancy and orofacial cleft in the offspring (odds ratio [OR] = 0.51, 95% confidence interval [CI] = 0.33-0.79). An unplanned pregnancy together with smoking in the first trimester of pregnancy resulted in almost treble the risk of a child with an orofacial cleft when compared with those who planned their pregnancy and did not smoke (OR = 2.92, CI = 1.50-5.65).
Conclusions:
Planned pregnancies were associated with a lower risk of orofacial clefts. Isolation of the elements of pregnancy planning implicated in these results is difficult. Current preconception advice needs to reach a wider audience; however, for maximum impact, efforts are needed to reduce the numbers of unplanned pregnancies.

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
