Description
Büsra Korkmaz's team studied weather factors and maternal traits linked to preterm birth in humid subtropical Türkiye, in a 2026 retrospective study. Preterm birth drives neonatal illness and death worldwide, yet evidence on weather effects is inconsistent and thin for humid subtropical areas. The team reviewed hospital birth records from January 2018 to December 2023 at a tertiary center in Rize. Monthly weather data from the NASA POWER database were matched to births by month and year.
Among 1767 deliveries, 681 were preterm, about 39 percent. Preterm birth was more common among women aged 35 or older, male infants, and first-time mothers. Relative humidity ran higher for preterm births than for term births, while other weather variables showed no significant difference in univariate tests. Age 35 or older and first-time motherhood also tracked with higher preterm likelihood in multivariable analysis.
