Back-Related Functional Limitations Among Full-Time Homemakers: A Comparison With Women Employed Full-Time Outside the Home
Bibliographic record
Abstract
In Brief Study Design. Two-year prospective study with repeated measurements. Objectives. To describe back-related functional limitations and their evolution among full-time female homemakers and to compare them to that of women employed full-time outside the home. Summary of Background Data. Back pain is not limited to the formal “working” population. However, there is little information on the consequences of back pain in “nonworking” individuals. Methods. Subjects were members of a large Health Maintenance Organization who consulted a physician for nonspecific back pain. Telephone interviews were conducted 4 to 6 weeks after the consultation and 1 and 2 years later. Back-related functional limitations were measured with a modified 16-item Roland-Morris scale. Analyses were conducted on 104 full-time homemakers and 288 women employed full-time outside the home. Results. The mean Roland-Morris score among homemakers was 34.4% at baseline and dropped to 22.8% at 2 years. In multiple regression analyses, 2-year back-related functional limitations were significantly associated with symptoms of depression, pain intensity, and the number of days with back pain in the past 6 months measured at baseline, but not with employment status. Functional limitations were not different between homemakers and women employed outside the home, even after adjustment for confounders. Conclusions. In this study, the functional consequences of back pain had a similar nature and 2-year evolution among full-time homemakers and women employed full-time outside the home. These results did notdemonstrate an effect of formal employment on the functional consequences of back pain among women. In this prospective study with repeated measurements, 104 female homemakers and 288 women employed outside the home who all consulted in a Health Maintenance Organization for back pain were followed for 2 years and compared. Back-related functional limitations and pain indexes measured at each of 3 interviews (baseline, 1 year, and 2 years) were not clinically or statistically different between homemakers and women employed outside the home, even after adjustment for confounders. These findings do not support a role of formal employment as a determinant of the functional consequences of back pain among women.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
