Do Meteorological Variations and Climate Changes Affect Hyperemesis Gravidarum?

Area of Science:

• Obstetrics and Gynecology
• Environmental Health
• Clinical Medicine

Background:

• Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting during pregnancy.
• Understanding factors influencing HG severity and hospitalization is crucial for patient care.

Purpose of the Study:

• To investigate the association between daily meteorological variations and climatological changes with hyperemesis gravidarum (HG).
• To analyze the impact of temperature, air pressure, humidity, and sunniness on HG symptom severity and hospitalization rates.

Main Methods:

• A retrospective study of 118 hospitalized HG patients.
• Patients were classified into mild, moderate, or severe HG based on the Pregnancy Unique Quantification of Emesis (PUQE-24) scale.
• Meteorological data (temperature, pressure, humidity, sunniness) and seasonal averages were collected and compared with HG grades.

Main Results:

• Hospitalization duration varied significantly across HG severity grades (mild, moderate, severe).
• No statistically significant differences were found in humidity, pressure, temperature, or sunniness levels related to HG grade.
• No significant relationship was identified between HG grades and seasonal conditions.

Conclusions:

• Meteorological and climate variations examined were independent of HG symptom severity and hospitalization rates in this cohort.
• The potential influence of broader climate changes on pregnancy outcomes warrants further investigation.
