Alcohol consumption and hip fracture risk
Abstract:
SUMMARY: The present meta-analysis shows that a nonlinear association between alcohol consumption and the risk of hip fracture was observed. Light alcohol consumption was inversely significantly associated with hip fracture risk, whereas heavy alcohol consumption was associated with an elevated hip fracture risk.
INTRODUCTION: Previous studies examining the association between alcohol consumption and the risk of hip fracture have reported conflicting findings. Therefore, we conducted a meta-analysis of prospective cohort studies to assess the association between alcohol consumption and the risk of hip fracture.
METHODS: PubMed and EMBASE were searched for prospective cohort studies on the relationship between alcohol consumption and the risk of hip fractures. Relative risks (RR) with 95% confidence intervals (CI) were derived using random-effects models throughout the whole analysis.
RESULTS: Eighteen prospective cohort studies were included with 3,730,424 participants and 26,168 hip fracture cases. Compared with non-drinkers, the pooled RR of hip fractures for alcohol consumption was 1.03 (95% CI, 0.91-1.15), with high heterogeneity between studies (P<0.001, I2=72.6%). A nonlinear relationship between alcohol consumption and the risk of hip fracture was identified (P nonlinearity=0.003). Compared with non-drinkers, the pooled RRs of hip fractures were 0.88 (95% CI, 0.83-0.89) for light alcohol consumption (0.01-12.5 g/day), 1.00 (95% CI, 0.85-1.14) for moderate alcohol consumption (12.6-49.9 g/day), and 1.71 (95% CI, 1.41-2.01) for heavy alcohol consumption (≥50 g/day).
CONCLUSIONS: There was no evidence of publication bias. In conclusion, a nonlinear association between alcohol consumption and the risk of hip fracture was observed in this meta-analysis. Further, light alcohol consumption was inversely significantly associated with hip fracture risk, whereas heavy alcohol consumption was associated with an elevated hip fracture risk.

El estudio observó una asociación entre el consumo de alcohol y el riesgo de fracturas de caderas. Las personas que consumen alcohol con moderación tenían menos probabilidades de sufrir una fractura de cadera que aquellos que presentaban un consumo alto. Se utilizaron dieciocho cohortes prospectivos que se encontraron utilizando las bases de datos PubMed y EMBASE.
The present study observed an association between consuming alcohol and the risk of hip fractures. People who consumed alcohol moderately were less likely to suffer a hip fracture than those who consumed alcohol heavily. Eighteen prospective cohorts were included and were found using the Pubmed and EMBASE databases.
