  • Abstract: Abstract Purpose The association between meteorological variables and risk of fractures has attracted increasing attentions but remain controversial. Therefore, our main aim is to clarify the association, and also to identify possible susceptible groups. Methods Relevant literature was obtained through standard MeSH literature searching seven electronic databases. Because some studies expressed the association as the rate of incidence (IRR) of fractures associated with each 1 °C rise in temperature and 1% increase in relative humidity (RH), some expressed as IRR of fractures for the day with specific climatic variable versus control days, and also the association was expressed as correlations coefficients (COR) in some studies, separated meta-analyses were undertaken, with one based on IRR and another based on COR. Results A total of 24 studies were included. Results showed that each 1 °C increase was significantly associated with a 3.0% decrease in fracture risk (IRR = 0.970, 95% CI : 0.952–0.988). The day with freezing rain and snow were associated with increased risk for both the lower extremity fracture (freezing rain: IRR = 1.174, 95% CI : 1.022–1.348; snow: IRR = 1.245, 95% CI : 1.050–1.477) and the upper extremity fracture (freezing rain: IRR = 1.376, 95% CI : 1.192–1.588; snow: IRR = 1.548, 95% CI : 1.361–1.761). No significant association was detected between RH, dew, frost, fog, storm and high wind, and fracture. The COR meta-analysis showed that mean temperature (moderately), maximum temperature (moderately), rainfall (weakly) and sunlight duration (weakly) were correlated with fracture occurrence. Conclusion The incidence of fractures was increased in lower temperature, the day with freezing rain, and snow. Other meteorological factors may have some effects on the incidence of fracture. The association maybe stronger for males, lower extremity fracture, and people living in Asia, subtropical zone, low-latitude, and northern hemisphere. Further studies are needed. Graphical abstract Unlabelled Image Highlights First meta-analysis to examine the association between temperature, humidity, and other meteorological factors and fractures. Temperature decrease increases fracture risk and current studies don't support the positive link for relative humidity. A significant association was found for freezing rain, snow, but not for RH, dew, frost, fog, storm and high wind. It is more effective to measure the association between temperature decrease and fracture risk on a daily time scale. Populations in Asia, subtropical zone, low-latitude, and northern hemisphere are vulnerable to temperature decrease.
