Ramadan fasting as a form of time-restricted eating during pregnancy and long-term health effects in offspring: a narrative systematic review.
Synthesis in BMC public health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundFasting and time-restricted eating (TRE) are popular practices that have health benefits, but may also carry a risk of harm. Little is known about the impact of TRE during pregnancy on the long-term health of offspring beyond the immediate post-natal period.
methodsWe conducted a systematic review and narrative synthesis of research on the health impact of time-restricted eating (TRE) during pregnancy and its potential long-term effects on offspring. We searched three electronic databases on 20 January 2023, and updated the search on 6 May 2024, combining search terms for pregnancy and fasting. Risk of bias was assessed using the ROBINS-E tool. We adhered to PRISMA and Synthesis Without Meta-analysis (SWiM) guidelines and the protocol was registered on PROSPERO (CRD42023387174).
resultsWe identified 16 studies with data for 1,895,744 total participants mainly set in countries around or close to the equator, published between 2004 and 2023. All studies focused on fasting during Ramadan, a religious custom practiced among Muslims worldwide that consists of refraining from food and drink from sunrise to sunset, that represents the most studied form of TRE. Outcomes included effects on body size, cognitive performance, disability, respiratory health, child mortality and general health.
conclusionsResults were consistent with the Developmental Origins of Health and Disease (DOHaD) model, showing offspring health risks associated with exposure to TRE during pregnancy. Body size was the most studied outcome and showed a strong correlation to exposure. The association between exposure and adverse effects appears to be stronger in low-income settings and becomes more apparent as the study sample grows older. Precautions should thus be taken by pregnant mothers when deciding whether to fast or not during their pregnancy. More research is needed to find a safe cut-off for time-restricted eating in different climates and socioeconomic settings.
