Growth patterns in ART children found different from those in naturally conceived – ESHRE



A large cohort study has shown that children conceived by ART are smaller at the time of delivery, experience a rapid catch-up growth, but are largely similar in height and weight to naturally conceived children at school age.

The influence of ART on healthy child development – physical, intellectual and mental – has been an ongoing concern which goes back to before the first IVF birth. Since then, an association between fertility treatment and adverse pregnancy outcomes has been well documented. A meta-analysis by researchers in China found a significantly increased risk of pre-term birth, low birth weight and small for gestational age; and a multicentre cohort study concluded that ICSI and IVF children need health care resources more than those naturally conceived.(1,2)

Less is known about how ART children continue to progress in terms of height, weight and body mass index when compared with those born without the help of fertility treatment. Now, a large ongoing long-term prospective cohort study has offered some clues by suggesting that fertility treatment may contribute to differences in growth patterns – at least in infancy – and that underlying parental subfertility may have an impact too.
However, the authors report that the ‘reassuring’ message for parents and clinics is that this effect does not persist beyond adolescence. Indeed, the growth patterns shown by ART children at the age of 17 are similar to those of their naturally conceived counterparts.

The findings are based on data from the Norwegian Mother, Father and Child Cohort Study (MoBa) on 81,461 singleton children (n = 79,740 naturally conceived; n = 1721 ART), and 544,113 teenagers screened for military service and entered in the Armed Forces Health Registry (which includes information on mode of conception).

For the MoBa children, researchers at the Norwegian Institute of Public Health in Oslo compared medical birth registry data according to mode of conception with maternally reported information from 18 weeks gestation to age seven. The ART children included those from fresh and frozen embryo transfer, while a small proportion (n = 5279) of the naturally conceived children were born to subfertile parents (<12 months to conception).(3)

The results showed that ART babies weighed less on average at delivery than those who were naturally conceived (3.495 kg vs 3.608 kg), and were shorter in length (50.2cm vs 50.5cm). However, those in all ART groups (ICSI, FET, etc) then experienced ‘rapid catch-up growth’, achieving greater height/weight by age three and a greater height by age seven. These growth patterns were similar among naturally conceived children born to the subfertile parents, although they were not as small as ART children at birth.

The study is also described as the first to show a difference in growth pattern in ART children up to school age. Compared with those naturally conceived, FET children were similar whereas those from fresh transfer ART were smaller; and FET children were longer/heavier for the first two years of life, and remained heavier up to age six. However, results for reported height, weight and BMI at age 17 from the Armed Forces Health Registry data were similar to those of all ART children.

So why do ART children grow differently in early life? While one likely explanation may lie in the ART procedures themselves (hormone treatments, culture media), the authors suggest the answer may also lie in ‘underlying factors influencing parental fertility problems’ given that the offspring from subfertile parents were also shown to have different growth patterns.

While the findings appear to allay concerns around growth rates overall, the need for follow-up research is clear according to the authors. Indeed, the authors in summarising their results report that ‘children conceived by ART are smaller at the time of delivery, experience a rapid catch-up growth, but are largely similar in length/height and weight to naturally conceived children at school age’, but go on to describe the term ‘catch-up growth’ as possibly misleading. They note that rapid weight gain in IVF children has been associated with raised blood pressure in teenage years and a greater risk of type 1 diabetes.(4,5) Thus, the potential cardiometabolic implications of accelerated growth rates among ART children in their first years of life should be investigated.

Inaugural art festival to showcase the work of artists in southwest Saskatchewan –



Since some tourists like to travel in September when crowds are smaller, an organization in southwest Saskatchewan wants to attract those people for an inaugural arts festival occurring in several area communities.

The Cypress Hills Grasslands Destination Area (CHGDA) organization has organized the first Southwest Art Fest, which encompasses multiple art genres such as painting, drawing, pottery, quilting, photography, film, music and other visual arts. 

The event runs from Sept. 1 to 30 and gives artists throughout that area the chance to showcase their artwork. Artists are encouraged to find a venue in which to feature their material and vice versa.

The CHGDA has 36 partners in dozens of communities throughout the province’s southwest corner and southeast Alberta.        

Blaine Filthaut, owner and artist with the Broken Spoke Fine Art Gallery and Gift Store in Maple Creek, explained that September is the best month for his business since “a different type of tourist travels at that time.” Furthermore, since there are few scheduled activities across the area, the CHGDA wanted to fill that month in an organized way. 

“The concept comes from almost like a city art walk, where you go on a third Thursday of the month are walks at this location, and you go,” he said. “And on those concepts, usually what happens is an artist finds a venue or a venue finds an artist that wants to participate.” 

However, an art walk is impossible for small towns, especially when they are scattered across more than 42,000 square kilometres of southwest Saskatchewan, Filthaut continued. This is unfortunate since there are “a huge amount of great artists” in the area. 

“Like the whole area, I’m saying there are many artists not well known, and art as a culture in Saskatchewan isn’t the highest thing on the list, either, so this is also a nice way to be promoting the arts,” he added.

This festival also helps address the issue of towns holding activities and their neighbours not knowing about them. This event ensures all municipalities are aware of what’s happening.

The CHGDA has a map on its website listing all 36 partners and the communities where they’re located. This is important, said Filthaut, since some tourists like to engage in “map quests” where they use Google maps to find lodgings and restaurants in communities and then visit those places. 

The organization’s area stretches from Leader in the northwest to Val Marie in the southeast. Although Swift Current is not included as a partner but is on Highway 1, the CHGDA approached art galleries in that community and convinced a few to participate in the festival. 

The festival provides a safe venue to tour, meet and discover art in southwest Saskatchewan in a COVID-19-safe environment, said Filthaut. That area of the province is also vast and diverse and features many kilometres of highway that pass through the sandhills, the grasslands, Cypress Hills and communities with great sights to discover.

The Cypress Hills Grasslands Destination Area spoke with Tourism Saskatchewan about this event, he continued, and while the government-run organization loved the idea, it was too late to support it due to uncertainty surrounding the pandemic. Yet, Tourism Saskatchewan said it might jump on board in 2022.

Even though the CHGDA could not obtain a provincial endorsement, the organization is still excited to host the month-long festival.

“We’re looking forward to it. Everybody I’ve talked with, including from the artistic side, they think it could be here for a long time. It’ll just grow … ,” added Filthaut. “Once you get on the map and do a show, it just builds. But somebody’s got to start it, and this is the start.”
