Association of Serum progesterone level, Peak Expiratory Flow Rate and obesity in healthy young women.

Abstract

Purpose: Obesity is one of the lifestyle disorders which is slowly and steadily extending throughout the world. Women especially are showing an upward shift in Body mass index (BMI) in this modern era. Obesity in females has been associated with various risk factors. Less studies have been explored on the influence of BMI on different parameters of menstrual cycle The purpose of the study was to determine the influence of BMI on different parameters of the menstrual cycle.

Methods: A total of 50 healthy female volunteers with regular menstrual cycle were selected after prior consent, and among them based on the body mass index, 32 females were categorized into obese group based on the BMI. Menstrual cycle history was monitored for 3 months for confirming regularity. Serum Progesterone and Peak expiratory flow rate (PEFR) were recorded.

Results: Progesterone levels were very highly significant in the luteal phase when compared to early follicular and ovulatory phase. The PEFR value in luteal phase was higher when compared to early follicular and ovulatory phase which was statistically highly significant. Positive correlation between progesterone and PEFR was observed in the luteal phase, but it was not statistically significant. Positive correlation between BMI and PEFR was also observed.

Conclusion: The study reveals significant hormonal and respiratory changes throughout the menstrual cycle. Progesterone levels and PEFR are markedly higher in the luteal phase, while BMI positively correlates with PEFR. A significant negative correlation exists between Waist Hip ratio (WHR) in the luteal phase. Further studies are needed to explore the underlying mechanisms driving the correlations between progesterone, respiratory parameters, BMI, and WHR in more diverse population.
