Abstract
Background. One of the four important components of the formation of cognitive functions is somatic health. But to date, there are no population studies that consider the relationship with cognitive functions and school performance of a large range of somatic factors, which allows us to compare the strength of their hypothetical contribution to cognitive functioning with each other. This study is the second part of a population-based study, the first part of which is presented in the previous publication "A Single-Stage Population-Based Study of the Prevalence of Mild Cognitive Impairment in Children of Secondary School Age". Aims — to determine the main patterns in the relationship between cognitive-academic and somatic factors in a cohort of Russian children, 5th grade students at school. Methods. In Russian schoolchildren of the 5th grades of municipalities representing cities of all federal districts of the Russian Federation, the links with integrative cognitive success, the number of subtests performed at the level of mild cognitive impairment, the results of individual cognitive subtests, academic performance and the leading hand factor were analyzed — the following somatic factors: the presence of skin pathology, bronchial asthma, orthopedic, ophthalmological disorders, visual acuity, body mass index, parameters of the study of the function of external respiration, electrocardiography, ultrasound examination of the thyroid gland, laboratory blood tests. Results. The results of the survey of 1036 participants, 51% of them girls, were admitted to the analysis. It has been established that iron content is directly related to integrative cognitive success and school performance, the relationship is especially strong between subgroups of iron content above and below 26.4 mmol/l. Clinical levels of erythrocytes are more strongly associated with integrative cognitive success and individual cognitive functions than other factors: in erythropenia cognitive parameters are worse. The presence of thyroid cysts directly correlates with some of the worst parameters of cognitive activity. High body mass index and low hemoglobin are associated with poorer academic performance. Conclusions. The results of the study for the first time on a cohort of Russian schoolchildren showed a connection with cognitive activity and school performance of a number of somatic factors, including iron content, which requires further in-depth study.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
