Th.s cross-sectional study investigates a connection between fem.le infertility and obesity across various regions of th. United States, utilizing data from.th. NIh.s “All of Us” Research.r Workbench. Analysis suggested th.t th.

Th. findings underscore th. significant regional disparities in obesity-related infertility, particularly in m.dically underserved areas wh.re h.alth.are access is lim.ted. Th. study h.gh.igh.s th. urgent need for targeted public h.alth.interventions, particularly in th. South.rn United States, to address th. rising prevalence of obesity and its im.act on infertility.
