NHANES 2017–2020: Anthropometric Obesity Indicators for Female Infertility Risk

A 2026 study by Yaru Yang analyzes data from 1154 reproductive-aged women in the U.S. National Health and Nutrition Examination Survey (NHANES) from 2017 to 2020. It evaluates the predictive performance of 16 anthropometric obesity indicators for female infertility risk, identifying 13 associated indicators. The Weight-Adjusted Waist Index (WWI) demonstrated slightly better predictive performance than other metrics like BMI.

Use Cases

• Comparing the predictive power of 16 obesity indicators for infertility risk based on the study's three-phase analytical framework.
• Developing logistic regression models for infertility prediction based on anthropometric data from NHANES.
• Assessing the clinical utility of obesity metrics like WWI, BMI, and CI using ROC curves and decision curve analysis as described.

Strengths

• Data is sourced from the nationally representative NHANES survey, covering 1154 women aged 18–45.
• The study systematically evaluates 16 distinct anthropometric obesity indicators, including BMI, WWI, and ABSI.
• Analysis includes 142 cases of infertility, providing a basis for predictive modeling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 2.0 MB DOCX file, which may require extraction and formatting for analysis.
