Research is one of the primary goals of Multiples of America.  By developing our own organizational surveys, we learn more about our multiples, our clubs and ourselves.  By partnering with the scientific community, we allow outside researchers to tap our membership for participants to learn more about our multiples’ medical, educational, or social nature and that research can have an impact on the greater good.   Whether you are a member or a non-member, we invite you to take part in our organizational surveys and/or contact the outside researchers and tell them you saw them on our website. Also, be sure to check out the section entitled Multiple Information for facts on twinning and current statistics on the incidence of multiple births.

Multiples of America Research Surveys

Current Research Surveys:


Multiples of America

New Survey



What is MBDB?  It is the Multiple Birth Data Base form. This form is to be filled out by a parent of multiples and will be used to enter information about you and your multiples into a CONFIDENTIAL, computerized data base maintained by the National Organization of Mothers of Twins Clubs, Inc. Complete this form only once. If you have more than one set of multiples, please fill out a separate form for each set.


Updates Needed– If you are a member who filled out the Multiple Birth Data Form before 2000, the Research Department is requesting for those Multiples of America members to take the time to fill this form out again. This is due to the fact that these files are not compatible with the new system currently being used on Survey Monkey.  If there is a question on when you filled out this form, please contact the Research Vice President or Chairman.

Expecting Multiples

Expecting multiples is a wonderful but challenging experience. Being prepared is the key to maintaining a healthy outlook. Multiples of America produces an annual pamphlet, Your Multiples and You (available in English and Spanish), which is filled with tips for preparing for multiples, tips for new parents, feeding tips and tips for maintaining a healthy pregnancy, as well as nutritional and educational information.

Higher Order Multiple Pregnancy

Higher Order Multiple (HOM) pregnancies are generally more high risk situation. According to the March of Dimes, the following are the average gestations seen in HOM pregnancies:

  • Triplets – 32 weeks
  • Quadruplets – 30 weeks
  • Quintuplets and higher – 29 weeks
  • Most preterm HOMs are generally under 2,500 grams (5.5 pounds) which is considered low birthweight.

The medical community continues to make great advances in managing care of both mother and babies, but there can be variations in level of experience and care, especially in areas that do not see many HOM births.  Expectant parents need to educate themselves about the HOM pregnancy and learn about seeking out a medical team (physician, hospital, nutritionist, etc.) with experience in managing triplet, quad or higher pregnancies

  • using protocols such as electronic fetal monitoring, special medications to halt or slow down contractions, strict bedrest, etc.
  • knowing the signs of preterm labor or other complications
  • preparing for caesarean birth (almost all HOM births are by C-section)
  • preparing for breastfeeding triplets or more by consulting a lactation expert and newborn nurses
