Infertility, defined as the inability to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse, has emerged as a significant public health concern globally. Affecting millions of women, infertility poses considerable challenges within reproductive health. Epidemiological research indicates that approximately 8–12% of couples of reproductive age experience difficulties in conceiving, with a substantial proportion of these cases linked to female-specific factors.
A key area of interest in understanding female infertility is the relationship between oxidative stress (OS) and reproductive health. Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body’s antioxidant defenses. This condition has been shown to adversely affect essential reproductive processes, including oocyte quality, folliculogenesis, and endometrial receptivity, thereby influencing a woman’s fertility potential.
The role of antioxidants in female reproductive health is underscored by the detrimental effects of oxidative stress. The composite dietary antioxidant index (CDAI) is a vital measure that quantifies the overall antioxidant capacity derived from an individual’s diet. This index considers the intake of various antioxidants, such as vitamins A, C, and E, zinc, selenium, and carotene. A higher CDAI score indicates a dietary pattern rich in antioxidants, which may help neutralize ROS and reduce oxidative damage in reproductive tissues. By evaluating the CDAI, researchers and clinicians can better understand how dietary antioxidants may affect oxidative stress levels and female fertility outcomes.
Understanding the CDAI involves recognizing the methodological details that enhance its reliability as an index. The calculation of the CDAI is based on the consumption levels of essential dietary antioxidants, adjusted for total energy intake to account for individual variations in diet and caloric requirements. This adjustment allows for a relative measure of antioxidant consumption that can be compared across diverse populations and dietary contexts. Moreover, the CDAI takes into account the cumulative effects of antioxidants, acknowledging that the protective benefits against oxidative stress arise from a synergistic interaction of multiple compounds rather than relying on a single nutrient.
Data from the National Health and Nutrition Examination Survey (NHANES) provides a comprehensive framework to investigate the relationship between dietary patterns and reproductive health in a diverse population. The NHANES database offers robust, representative data on nutritional habits and health outcomes, facilitating exploration of how dietary antioxidant intake correlates with female fertility parameters. This research aims to deliver practical insights that could inform dietary recommendations for women facing fertility challenges, potentially aiding in the management of infertility through improved nutritional strategies.
