Core Findings and Their Evidentiary Weight

The paper (Brodska & Makarenko, Medicine Today and Tomorrow 94(2), 2025) is a descriptive sociological questionnaire study of 200 Ukrainian women aged 48-72 (174 in menopause), surveyed autumn-winter 2024-2025. Key reported values: 84.0% awareness of menopausal mineral deficiency; 82.0% taking calcium + vitamin D3 for prevention, of whom roughly one in four bought products in supermarkets without reading instructions; 51.5% relying on physician visits or doctor-blogger videos; only 15.0% aware of bone-mineralization blood tests, and just 2.0% had testing followed by physician-guided medication; ~66.0% only partially/episodically included calcium-rich foods despite awareness. Brand-level data: Calcium-D3 Nycomed chosen by 76%, Calcemin Advance 12%, Calcyker 5%, calcium gluconate and Osteokea 2% each, chelated calcium 1% Methods and reported statistics of the survey

Where the Evidence Is Uncertain

Self-report without verification. Menopause status, medication use, and purchase locations were all self-reported; no pharmacy records, doses, or duration were verified Study blindspots and missing controls

Sampling weakness. No sampling frame or recruitment setting is described; the two-group design (<5 vs >5 years since last menstruation) is defined but no between-group results are ever reported — a structural oddity suggesting post-hoc group creation was never used analytically.

Clinical context the survey omits. The discussion is rich, but the data cannot speak to whether supplementation was appropriate. A Cochrane review found vitamin D alone unlikely to prevent fractures (hip fracture RR 1.15, 95% CI 0.99-1.33) while vitamin D with calcium reduced hip fracture risk mainly in institutionalized older adults (RR 0.84, 95% CI 0.73-0.96), with hypercalcemia RR 2.35 vs placebo — so unsupervised supplementation is not risk-free Cochrane meta-analysis on vitamin D fracture prevention And elevated calcium intake concerns about cardiovascular risk noted in Brazilian guidance are cited by the authors themselves Brazilian epidemiology viewpoint on osteoporosis management

Critique and Comparisons

Relative to the conceptually similar Palmerston North knowledge survey (which used a validated instrument, the OKT, and statistical testing: p=0.002 and p=0.010 for group differences), this paper uses an unvalidated bespoke questionnaire and explicitly reports "statistical hypotheses were not tested" Validated osteoporosis knowledge survey comparator Percentages are given without confidence intervals; with N=200, a 2.0% figure represents only 4 women, so any inference from it is fragile. The "84% awareness" claim is also internally in tension with the authors' own discussion stating only every third woman knew food benefits well — different questions, but the abstract-level framing risks overstating knowledge. Internal inconsistency: the abstract states 15.0% believed balanced diet corrects mineral loss, while the results text frames this differently; imprecise denominators (82% of 200 vs 82% of the 174 menopausal subgroup) are never clarified.

The paper's most defensible contribution is documenting the supermarket-purchase/never-read-instructions behavior (~25% of supplement users) and the 41-fold gap between supplementation (82%) and testing-guided use (2%). This pattern is plausible and consistent with the knowledge-practice gap literature, but the conclusion that "high uncontrolled self-medication" exists rests entirely on self-report in an unknown sample. What would change this conclusion: pharmacy-purchase audits or linked laboratory data showing most calcium+D3 users had prescriptions and monitoring.

Verdict

A modest, locally useful descriptive snapshot with genuine public-health relevance for wartime Ukraine's health-information landscape, but weak methodology: no validated instrument, no inferential statistics, no sampling design, no dose or BMD data, and numerator-level fragility at low percentages. Its claims should be treated as hypothesis-generating, not as prevalence estimates. Confidence: moderate for the direction of findings; low for exact percentages.

 BGPT Paper Review

Study Novelty

Self-medication of calcium/vitamin D by menopausal women is a well-documented topic; the paper's new contribution is only its Ukrainian wartime-context data point, previously unstudied.

Scientific Quality

Unvalidated questionnaire, no sampling frame, purely descriptive statistics without CIs, unreported group comparisons despite defining groups, internal inconsistencies in denominators and framing, and small numerators for headline claims (2.0% = 4 women).

Study Generality

Findings are restricted to one unspecified Ukrainian sample with no generalizable sampling design; the discussion generalizes to Brazil and Austria without quantitative comparability.

Study Usefulness

Locally useful for Ukrainian public-health planning: documents the supermarket-purchase behavior and the 82%-vs-2% supplementation-to-testing gap, which can guide targeted education.

Study Reproducibility

Questionnaire structure and sample size are described, but no full instrument, no sampling/recruitment details, no raw data or data-sharing, and manual data processing limit exact replication.
