A multistage sampling followed by systematic random sampling was used to collect the data. Students' academic performance (AP) was evaluated by computing two-semester average grade scores of the 2016/17 academic year in all disciplines using the school record. A pre-tested, interviewer-administered, structured questionnaire was used to collect the data. To assess nutritional status, the z scores of height for age (HAZ) and BMI for age (BAZ) were employed according to WHO's new reference values. The WHO Anthroplus software was used to generate nutritional indices. A structural equation model (SEM) was used to examine the direct, indirect, and total effects of the dietary diversity score (DDS), HAZ score, and BAZ score on AP.

However, the universally recognized cutoffs for these measures may be inadequate for individuals of Ethiopian descent. Due to the lack of universally applicable cutoffs, studies recommend tailoring the optimal screening thresholds to each population's specific characteristics. Therefore, this study aimed to determine body composition-based WC, WHR, and WHtR cutoffs for the healthy adult population of Ethiopia.</p><p><strong>Method: </strong>A population based cross-sectional study was conducted in the Amhara region of Ethiopia from June to August 2023, collecting anthropometric and body composition data from 838 adult participants.

The new proposed cutoff values for waist circumference, hip circumference, and waist-to-height ratio had sensitivity ranging 76-93% and specificity of 83-94% in accurately identifying obesity. The current study also determined the cut-off values for underweight, normal weight, and overweight body weight categories. Accordingly, for men, the WC cut-offs were: ≤ 74.55 cm (underweight), 74.56-78.95 cm (normal), and 79.0-85.0 cm (overweight). For women, the cut-offs were: ≤ 68.25 cm (underweight), 68.26-79.59 cm (normal), and 79.60-81.10 cm (overweight). The WHtR thresholds were: ≤0.43 (underweight), 0.44-0.47 (normal), and 0.48-0.53 (overweight) in men; ≤0.43 (underweight), 0.44-0.50 (normal), and 0.50-0.51 (overweight) in women.</p><p><strong>Conclusion: </strong>The findings indicate that the WC, WHR, and WHtR cutoff values for defining obesity in Ethiopian adults are lower than international standards.
