In January 2024, researchers at Aga Khan College (AKU) in Pakistan’s Sindh province, launched an bold four-year undertaking to measure the affect of maximum warmth on maternal and youngster well being.
Research on the affect of the local weather disaster, rising warmth and the affect on pregnant girls have been undertaken in different international locations, however till now there was restricted analysis in Pakistan. That is even though human-induced local weather change is making heatwaves much more possible throughout South Asia.
“We’re linking current knowledge [as well as conducting new research focussing] on girls who had been pregnant throughout scorching months,” says Jai Das, assistant professor on the Division of Paediatrics and Baby Well being at AKU.
“We’ll evaluate these findings to knowledge gathered from girls who had been pregnant in delicate climate or the winter season,” he tells The Third Pole. Das, who’s the principal investigator overseeing the undertaking, says that in recent times “we’ve seen a surge of curiosity within the area of local weather change and its affect on well being in Pakistan”.
Funded by the UK-based charity Wellcome Belief, the undertaking will collect knowledge from 6,000 girls from the districts of Tando Muhammad Khan, Tharparkar and Matiari in Sindh.
The undertaking may also cowl girls from low-income neighbourhoods within the metropolis of Karachi, equivalent to Kharadar, Dhobi Ghat and Korangi. Muhammad Khan Jamali, the undertaking’s analysis supervisor, tells The Third Pole: “Many elements overlap relating to the impacts on maternal and youngster well being, however excessive local weather is definitely considered one of them. For instance, girls in congested city areas dwelling in small flats undergo in excessive warmth – particularly if they’re pregnant – as they stand in entrance of the range,” says Jamali.
These examples spotlight varied social and financial constraints confronted by girls, together with the expectation they prepare dinner throughout being pregnant, restricted dwelling house and insufficient cooling choices. All of those challenges are compounded by rising temperatures, that are set to extend 2-5˚C by 2100 in Sindh, in response to local weather change projections.
The undertaking will assist to find out the roles these elements play, with taking part girls given gadgets to put on and place of their houses that monitor the temperatures they’re experiencing. Das says that analysing precisely how warmth stress impacts the well being of pregnant girls and their foetuses will assist “tailor options”.
Local weather vulnerability, excessive maternal mortality and stillbirths
The undertaking comes at a important time, with Pakistan ranked because the eighth most susceptible nation to local weather impacts. Water shortage, one of many points most exacerbated by local weather change, disproportionately impacts girls, but they’re ceaselessly excluded from decision-making processes.
In water-scarce areas like Tharparkar in Sindh, girls bear the burden of carrying a median of 90 litres over lengthy distances, to satisfy their home wants, together with cooking, ingesting and washing, even throughout being pregnant.

Local weather impacts and water shortage are added stresses in a rustic with one of many highest neonatal mortality charges on this planet. In 2019, a world research discovered that 33% of stillbirths occurred in South Asia. Pakistan had a median of 30.6 stillbirths per thousand in 2019, which was a big enchancment from 39.9 in 2000, however nonetheless far above the regional common of 18.2, or the worldwide common of 13.9.
Pregnant girls and the menace from warmth
Nadeem Zuberi, vice-chair and professor at AKU’s Division of Obstetrics and Gynaecology, says it’s “excessive time” there’s a give attention to the hyperlink between obstetric and foetal well being and local weather change.
Safia Manzoor, an obstetrician and gynaecologist working for the donor-funded Lyari Common Hospital in considered one of Karachi’s low revenue areas, says: “We see extra instances of pre-term births in scorching climate.” The AKU-based research is hoping to maneuver past this sort of anecdotal knowledge to determine how precisely warmth stress impacts pregnant girls.
Nusrat Bano, a Girl Well being Customer (LHV), a healthcare supplier providing fundamental nursing care and maternal and youngster well being providers in Tharparkar, says: “In 2023, [over six weeks in March and April], I noticed extra infants born prematurely than ever earlier than. Principally they had been born within the eighth month; most of them didn’t survive.”
Whereas this era coincided with heatwaves, infants born within the eighth month don’t sometimes die except there are different elements at play. The proposed analysis might be able to make clear how heatwaves contribute to neonatal mortality, outlined as demise inside the first 28 days of life, in Pakistan.
Warmth stress and temperature fluctuations have a better affect on pregnant girls, explains Zuberi, due to the hormonal adjustments the physique goes by means of.
Jamali says that whereas there’s a dearth of evidence-based knowledge on this regard, there’s “sufficient experiential and anecdotal knowledge to verify” that the numbers of maternal and youngster well being challenges have elevated, particularly in excessive warmth durations.
“Native communities are actually becoming a member of the dots and saying that youngsters are born with low beginning weight or prematurely in excessive summers,” he says, hoping that the research will enable consultants to “relate particular exposures to excessive warmth occasions on the inhabitants degree to scientific and physiological outcomes in being pregnant”.
He provides: “It will present invaluable data to plot believable mitigation methods and interventions for hundreds of thousands of moms and infants in susceptible populations.”
