The mortality rates among term infant births were 0.03, 0.24, and 5.24%, respectively, for singletons, twin, and triplet or higher-order multiple gestation births. The aOR for mortality in term twin neonates was higher (5.263, 95% CI: 4.524–6.122, p < 0.0001) when compared to singletons.

Are twins more likely to have health problems?
Multiples are about twice as likely as singleton babies to have birth defects, including neural tube defects (such as spina bifida), cerebral palsy, congenital heart defects and birth defects that affect the digestive system.
Are twins more successful than singletons?
Conclusions These data support the proposition that twins perform less well academically than singletons. Low birth weight has a negative association with subsequent academic achievement in early adulthood, with the effect being stronger for twins than for singletons.
How are twins different from singletons?
Singletons interact with you, family members, and friends. Twins, in addition to you, family members, and friends, have a constant companion with whom they have been interacting even before birth. Twins offer a unique opportunity for parents to observe how their children interact with each other.
Are twins easier than singletons?
Twins are easier than one baby, or as us twins moms call one baby: a singleton. That’s right, my twins are easier that my son was on his own, or my oldest daughter was on her own. Of course, there are a lot of factors, like the fact that my almost one-year-old old twins are happy babies by nature.
Do twins have a lower IQ?
On average, twins have lower IQ scores at 7 and 9 years old than singleton children in the same family. In a cohort study, Ronalds and colleagues (p 1306) used data on 9832 singletons and 236 twins born in Aberdeen between 1950 and 1956.
Are twins more likely to have autism?
Using a mathematical analysis of data, his team found that identical twins were much more likely to have similar levels of autistic symptoms than fraternal twins. Those researchers also concluded that: High levels of autism symptoms are genetic in origin. Less severe symptoms are not as likely to be inherited.
Are twins harder to raise?
“Having twins is not twice as hard—it’s exponentially more difficult,” says Natalie Diaz, author of What To Do When You’re Having Two and CEO of Twiniversity, a global support network for parents of twins.
How much harder is a twin pregnancy?
7: If you’re pregnant with twins, you may gain more weight than if you’re carrying one child. “With twins, mothers gain more weight as there are two babies, two placentas, and more amniotic fluid,” says Al-Khan. “You also need more calories for twin pregnancies.”
What is the survival rate of twin?
The overall survival rate was 313/354 (88%) with 146/177 (82%) pregnancies resulting in survival of both twins, 21/177 (12%) in survival of one twin and 10/177 (6%) in loss of both twins.
Is belly bigger with twins?
Your belly may grow bigger, and you may gain more weight, sooner. Talk to your doctor about how much you might expect to gain. When you’re carrying twins, you and your babies may be tested and checked more than you would for a single-baby pregnancy.
Do twins have lower cognitive ability than singletons?
Most recently, a study was reported that used the Netherlands twin registry to look at differences within families in cognition between 260 adult twins and 98 of their singleton siblings. This found no evidence for a difference in cognitive ability between singletons and twins in the same family.
Do you bloat more with twins?
If you’re pregnant with twins, you might gain 16-20 kg (compared to 10-15 kg with a single pregnancy). Also, stretch marks, bloating, varicose veins and haemorrhoids are common. These changes might affect the way you feel about your body.
Are twins happier?
They examined reported levels of happiness in 1,300 sets of identical and fraternal twins. Identical twins reported similar levels of happiness, while fraternal twins exhibited greater variation in their reported sense of well-being.
Do twins sleep better together?
Risks and Benefits of Twins Sleeping Together
1 Multiples who are co-bedded seem to sleep better, gain weight better, have fewer episodes of apnea and bradycardia, and (as long as they’re about the same size), keep each other warm.
Do you need 2 cots for twins?
You can put your twins to sleep in a single cot while they’re small enough. This is called co-bedding and is perfectly safe. In fact, putting twins in the same cot can help them regulate their body temperatures and sleep cycles, and can soothe them and their twin.
Do twins have a shorter life span?
While twins have been subjects in countless studies that try to separate the effects of nature from nurture, a recent study in PLOS ONE is the first to actually look at what being a twin means for life expectancy. Analysis shows that twins have lower mortality rates for both sexes throughout their lifetimes.
Are twins smarter than singletons?
Twins on the average seem to have lower IQs than singletons. The best estimate for this group difference is 4.2 IQ points (less than one-third of a standard deviation), with a great divide between study outcomes of less vs more recent birth cohorts (5.1 vs 0.5 IQ points, respectively).
Do twins have worse outcomes?
Children born as twins have a greater likelihood of poor neurodevelopmental outcomes compared to singletons when birth weight and gestational age are not controlled for (Lorenz, 2012).
Why do so many twins have autism?
Studies in twins have shown that autism has genetic origins: A child is more likely to have autism if his or her sibling or twin also has the disorder. But there is also evidence that factors other than genetics, collectively referred to as ‘the environment,’ play a role.
How often do twins have autism?
Based on data from 192 pairs of twins, the new study found a concordance rate for autism spectrum disorders of 77 percent among identical twin boys and 31 percent among fraternal twin boys.
