This cross-sectional study investigates a connection between female infertility and obesity across various regions of the United States, utilizing data from the NIH’s “All of Us” Researcher Workbench. Analysis suggested that the Southern region exhibited the highest percentage of concurrently infertile and obese females at 32.3%, in contrast to the lowest in the Western region at 28.7%. The findings underscore the significant regional disparities in obesity-related infertility, particularly in medically underserved areas where healthcare access is limited. The study highlights the urgent need for targeted public health interventions, particularly in the Southern United States, to address the rising prevalence of obesity and its impact on infertility. Further, these results advocate for enhanced public health education and policies aimed at improving healthcare accessibility, with the goal of mitigating the adverse effects of obesity on reproductive health.

Accessing drinking water is a global issue. This study aims to contribute to the assessment of groundwater quality in the municipality of Za-Kpota (southern Benin) using remote sensing and machine Learning. The methodological approach used consisted in linking groundwater physico-chemical parameter data collected in the field and in the laboratory using AFNOR 1994 standardized methods to satellite data (Landsat) in order to sketch out a groundwater quality prediction model. The data was processed using QGis (Semi-Automatic Plugin: SCP) and Python (Jupyter Netebook: Prediction) softwares. The results of water analysis from the sampled wells and boreholes indicated that most of the water is acidic (pH varying between 5.59 and 7.83). The water was moderately mineralized, with conductivity values of less than 1500 μs/cm overall (59 µS/cm to 1344 µS/cm), with high concentrations of nitrates and phosphates in places. The dynamics of groundwater quality in the municipality of Za-Kpota between 2008 and 2022 are also marked by a regression in land use units (a regression in vegetation and marshland formation in favor of built-up areas, bare soil, crops and fallow land) revealed by the diachronic analysis of satellite images from 2008, 2013, 2018 and 2022. Surveys of local residents revealed the use of herbicides and pesticides in agricultural fields, which are the main drivers contributing to the groundwater quality deterioration observed in the study area. Field surveys revealed the use of herbicides and pesticides in agricultural fields, which are factors contributing to the deterioration in groundwater quality observed in the study area. The results of the groundwater quality prediction models (ANN, RF and LR) developed led to the conclusion that the model based on Artificial Neural Networks (ANN: R2 = 0.97 and RmSE = 0) is the best for groundwater quality changes modelling in the Za-Kpota municipality.
