During Ramadan, Muslims abstain from eating, drinkingfrom sunrise to sunset. There have been reports that Ramadan results in altered sleep patterns, as well as changes in lifestyle habits. To date, there are no studies that have examined the effects of fasting on metabolic and sleep during Ramadan in individuals with type 2 diabetes mellitus (T2DM). Because sleep quality and quantity can affect glycemic control among individuals with T2DM, we assessed the effects of fasting on changes in sleep and glycemic control in these individuals.
Participants were recruited if they had been diagnosed with T2DM with an intention to fast for at least15 days during Ramadan. Participants were requested to wear a Jawbone (San Francisco, CA, USA) Up24 wristband for a week before the start of Ramadan (between 1 and 10 June 2015), which served as the baseline, and during Ramadan for 1 week while maintaining their regular daily sleep habits during this period.
