Assessing the Impact of High Body Mass Index (BMI) on the Efficacy of Assisted Reproductive Technologies (ART) in Saudi Women: A Cross-Sectional Study Examining Ovarian Reserve and Treatment Outcomes

INTRODUCTION

The global surge in high body mass index (BMI) and obesity has led to various health complications. While numerous studies have shown that obesity disrupts female fertility, the specific effects of obesity on the success rate of assisted reproductive technology (ART) treatments in Saudi women have been less explored. This study aimed to delve into this gap, especially focusing on the correlation between BMI, ovarian reserve parameters, and ART outcomes among Saudi women.

METHODS

A cross-sectional study was carried out from January to August 2023, concentrating on Saudi women aged 18 and above who underwent ART treatments for infertility. A total of 1071 women participated, with 155 completing an online survey and 916 responding through a hard copy from several Saudi hospitals. The data encompassed demographics, medical history, anthropometric details, ovarian reserve parameters, and ART results. For the analysis, Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 28.0, Armonk, NY) was utilized, applying descriptive statistics, the Chi-square test, and a linear regression model to discern connections between BMI, participant characteristics, and ART outcomes. A p-value of less than 0.05 was considered statistically significant.

RESULTS

Most participants were aged 25-34 (406) years and held a bachelor's degree (707). Over half (560) received fertility treatments in the past, with 37.9% (406) having polycystic ovary syndrome (PCOS) and 23.5% (252) with other fertility-impacting medical conditions. Interestingly, 62.1% (665) had not undergone any ART cycles. Of those who did, 51.6% (553) had clinical pregnancies leading to live births. About 23.8% (308) of those with clinical pregnancies faced miscarriages without successful live births. Furthermore, 17.6% (189) reported complications or side effects from past ART procedures, and 31.4% (336) were on ART-related medications or supplements. The linear regression highlighted that individuals with normal weight tended to undergo more ART cycles. However, those with a higher BMI exhibited increased chances of achieving clinical pregnancies and live births.

CONCLUSION

The study underscores the crucial relationship between BMI and ART efficacy in Saudi women. The data reveals that BMI can significantly influence ART treatment outcomes, especially concerning the number of cycles, clinical pregnancies, and live births. Consequently, BMI should be an essential consideration when evaluating and optimizing the success rates of ART procedures.
