Does fasting increase rates of trauma in Ramadan? A systematic review.

BACKGROUND

As part of their religious obligation, Muslims abstain from food and drink from dawn until dusk for a 30-day period during Ramadan. Fasting may affect daily functioning, such as increased risk of collision for drivers. A study of the impact of fasting during Ramadan on trauma incidence may allow for the creation of public health campaigns targeting this potential phenomenon. We aimed to determine whether trauma incidence increases during Ramadan, and to characterise the trauma occurring during Ramadan.

METHODS

Both published and unpublished literature, along with conference proceedings and reference lists from the selected studies, were searched up until the 1 of July 2023. A narrative synthesis was conducted, and the included studies were evaluated using appropriate tools based on their study design.

RESULTS

Seventeen studies (964,631 subjects) were included. There were methodological concerns pertaining to their low level of evidence and risk of bias. Of nine studies reporting on road traffic accidents (RTAs), six found a higher incidence during Ramadan. Road traffic accidents and occupational injuries (OIs) were more likely to occur near or at sunset (marking the end of the fast). Two studies presented conflicting evidence regarding the effect of fasting in Ramadan on sports-associated injuries. Current evidence suggests that falls and violence-related trauma do not occur more frequently during Ramadan, with insufficient evidence to determine the occurrence of other injury mechanisms.

CONCLUSION

Individuals who fast may be at a higher risk of RTAs and OIs during Ramadan than outside this month. Due to the lack of studies performed in the Americas and Europe, it is unclear whether the findings are applicable to these regions. Current evidence is limited by lack of stratification according to time of trauma occurrence, and high risk of bias.
