The objective of this study is to assess whether high consumption of UPF is associated with female infertility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional analysis of females aged 18\u201345\u202fyears who participated in the National Health and Nutrition Examination Survey (NHANES) from 2013 to 2018 was performed. Females were eligible for inclusion if they provided a 24-h dietary recall and responded to a question regarding infertility. Foods reported during a 24-h dietary recall were classified according to the Nova system. The relative percentage of total energy consumed from UPF and unprocessed\/minimally processed foods within a 24-h period was calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The prevalence of infertility was 11%. The overall mean percentage of daily UPF and unprocessed\/minimally processed food intake among respondents was 57 and 29%, respectively. There was no difference in the odds of female infertility when comparing females in the lowest tertile of UPF consumption to peers in the middle [aOR\u202f=\u202f1.37, 95% CI (0.96, 1.95)] or highest tertile of consumption [aOR\u202f=\u202f1.26, 95% CI (0.91, 1.74)]. Similarly, there was no difference in the odds of infertility between participants in the middle [aOR\u202f=\u202f1.39, 95% CI (0.83, 2.33)] or highest tertile [aOR\u202f=\u202f0.73, 95% CI (0.34, 1.54)] of unprocessed\/minimally processed food consumption relative to those in the lowest tertile. In an intermediate model removing body mass index (BMI) as a covariate, an increased odds of infertility was noted among females with the highest tertile of UPF consumption relative to those in the lowest tertile [aOR\u202f=\u202f1.46, 95% CI (1.01, 2.09)].<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Among women of reproductive age, high consumption of UPF is associated with female infertility.
