“… 10 Several studies have shown that obesity increases the risk of prenatal complications such as gestational hypertension and gestational diabetes. 11–13 It is also responsible for prolonging labor, increasing the risk of obstructed labor and cesarean delivery, 14 and has notable effects on the fetus. 12 , 15 , 16 Recent animal experiments have shown that lean and obese animals are typically less fertile, but not necessarily in humans.…”

Purpose This study aimed to investigate the effects of body mass index (BMI) on infertility in women of childbearing age. Patients and Methods We performed a cross-sectional study using data from 3624 participants from the National Health and Nutrition Examination Survey (NHANES). We used BMI and fertility status in the survey as independent and dependent variables, respectively. We evaluated their relationship and used smoothed curve fitting and multivariate logistic regression analysis as well as a generalized additive model (GAM) to determine the effect of BMI. Results Logistic regression model analysis linked BMI and infertility after adjusting for potential confounders OR 1.03, 95%Cl: 1.02–1.05). There was a non-linear relationship between BMI and infertility, with each unit increase in BMI reducing the risk of infertility by 33% when BMI was <19.5 kg/m 2 . In contrast, when BMI ≥19.5 kg/m 2 , each unit increase in BMI predicted a 3% increase in the risk of infertility. Conclusion The relationship between infertility and BMI presented a U-shaped curve. Therefore, a BMI that lay at the extremes of the spectrum tended to predict infertility. We believe that this study will support the maintenance of suitable BMI levels in women preparing for pregnancy.

“…Simply put, they refer to the excessive accumulation of body fat, reaching levels detrimental to one's health. This condition arises primarily from a chronic imbalance between calorie intake and energy expenditure (Escobar et al, 2021). Body mass index (BMI) is a standard measure in epidemiological studies, offering an estimate of body fat based on an individual's height and weight (Brenes-Monge et al, 2019;Kim et al, 2021;Piirtola et al, 2020).…”

Infertility, defined as the inability to conceive after one year of regular unprotected intercourse, affects millions of couples worldwide, with prevalence rates varying across developed and developing nations. The main objective of the study is to find the association between low BMI and anovulation with primary infertility in women of reproductive age. This cross-sectional study was conducted in Khyber Teaching Hospital Peshawar from January 2023 to December 2023. A total of 340 female participants were added using convenient sampling methods. Data collection consisted of comprehensive clinical evaluations, including anthropometric measurements to assess BMI, hormonal assays to determine ovulatory status and detailed reproductive histories. BMI was calculated as weight in kilograms divided by height in meters squared (kg/m^2), with participants categorized into low BMI (BMI < 18.5 kg/m^2) and normal BMI (BMI ≥ 18.5 kg/m^2) groups. Data were collected from 340 female participants. The mean age was 28.5± 4.2 years for those with low BMI and 30.1± 3.8 years for those with normal BMI. Among underweight individuals, 50 were classified as infertile and 20 as fertile, totaling 70 participants. Of normal-weight individuals, 40 were infertile, and 120 were fertile, totaling 160 participants. In the overweight group, 30 were barren, and 50 were fertile, totaling 80 participants. Low BMI showed a significantly increased adjusted odds ratio (AOR) of 3.00 (95% CI: 1.80 - 5.00, p < 0.001) for infertility. Age, socioeconomic status, smoking, and alcohol consumption did not show significant associations with infertility. It is concluded that low BMI is significantly associated with an increased risk of anovulation and primary infertility in women of reproductive age, even after accounting for potential confounders.

“…Although the latest data show that C/S implementation is 21% worldwide, this rate is predicted to approach 30% between 2021 and 2030 ( 9 ) . According to the Organization for Economic Co-operation and Development (OECD) 2020 data, TR has the highest rate after Mexico (58%), with a C/S rate of 57% (573/1000 live births) ( 10 ) . In our study, data for 2022 show that C/S application is 60.5% in TR.…”

“…This shows that cesarean delivery has increased exponentially in the last 20 years ( 4 ) . Indications for cesarean section include maternal pelvic deformity, eclampsia and HELLP syndrome, fetal stress, cord prolapse, placenta previa, uterine rupture, previous cesarean delivery history, prolonged delivery, fetal presentation, and major antepartum hemorrhage ( 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ) . Studies in the literature also show that cesarean section operations performed within indications are lifesaving.…”

Objective: The aim of our study, in light of the World Health Organization Multi-Country Survey (WHO-MCS) data examining the data of the Ministry of Health for the year 2022, comparing the cesarean sections (C/S) performed in the Republic of Turkey (TR) with the WHO-MCS data, and comparing the number of cesarean sections applied more than the reference values. Materials and Methods: According to the database of the Turkish Ministry of Health, in 2022, 1166175 deliveries took place in the Republic of Turkey, and 706370 (60.5%) cesarean section deliveries were recorded as 365764 (51%) primary C/S. Using the Ministry of Health registration system based on the Robson classification. Results: The number and rate of C/S operations performed per birth in 2022 in TR (n=706370; 60.50%) were found to be significantly higher when compared to the number and rate of C/S on a global scale (n=246062; 21.10%), (p<0.001). When cesarean section operations performed in the Ministry of Health hospitals, private institutions, foundation universities, public universities and other public unit hospitals were compared with WHO MCS reference values and C/S ratios, 44.2% versus 24.7% (p=0.05), versus 77.4%, versus 34.2% (p<0.001), 74.3% versus 29.5% (p<0.001), 75% versus 35.8% (p<0.001), 69.3% versus 35.9% (p<0.001). Conclusion: The amount of cesarean sections performed according to the total number of births in the Turkish Republic is relatively high and its cost nearly 1 billion 750 million TL.
