Assessment of peak bone mineral density and its associated factors in Vietnamese adults: A cross-sectional study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionOsteoporosis is a growing public health concern in Vietnam, yet population-specific reference data for peak bone mineral density (PBD) remain limited. This study aimed to establish a standard PBD dataset and identify factors associated with bone mineral density (BMD) in Vietnamese adults.
methodsA cross-sectional study included 1,378 participants (410 men, 968 women) in Hue City, Vietnam. BMD was measured at the lumbar spine (LS), femoral neck (FN), and total hip (TH) using dual-energy X-ray absorptiometry (DXA). A cubic polynomial regression models were performed to identify peak bone density (PBD). Age-standardized prevalence of osteoporosis was calculated using the 2024 Vietnamese population structure.
resultsMen exhibited higher BMD than women across all skeletal sites. The estimated age of PBD attainment was 20-29 years in men and approximately 30 years in women. Age was the strongest negative predictor of BMD, while body weight and height showed positive correlations. The age-standardized prevalence of osteoporosis was highest at the LS (33.58%), followed by the TH (12.77%) and FN (2.69%). Women showed a markedly higher prevalence than men, with a sharp increase observed after menopause.
conclusionThis study provides an updated reference dataset for PBD in the Vietnamese population, notably revealing that men attain peak bone density earlier than women. Furthermore, the findings underscore the high prevalence of osteoporosis at the lumbar spine, suggesting a need for early screening strategies targeting high-risk groups.
