ABSTRACT

Chronic insomnia symptoms are prevalent among adults. Current treatment strategies for chronic insomnia are restricted by shortcomings such as the side effects of pharmaceutical treatments, and high economic cost of cognitive behavioral treatment. Thus alternative methods for mitigating insomnia symptoms are needed. Accumulating evidence suggests that lifestyle factors, such as sedentary behavior and unbalanced diet are associated with sleep and/or insomnia symptoms. However, there is a lack of studies focusing on the overweight insomniac population, and randomized controlled trials concerning the effects of exercise and diet on insomnia symptoms are scarce.

In the present study, we aimed to investigate behavioral factors that are related to chronic insomnia symptoms among overweight and obese men. The effects of aerobic exercise and diet intervention on sleep among this population were also studied. The results showed that low level of leisure-time physical activity and high consumption of saturated fatty acid were independently associated with chronic insomnia symptoms. Six months of regular aerobic exercise training tailored by fitness level improved sleep in insomniacs by curtailing the objectively measured sleep onset latency and reducing the frequency of difficulty falling asleep. Moreover, a 6-month diet intervention also shortened the objective sleep onset latency in this population. This work highlights the associations between obesity-related lifestyle factors and chronic insomnia symptoms. Furthermore, by showing their effects on improving sleep, the study suggests a possibility of including exercise and diet intervention in the treatment strategies of chronic insomnia among overweight and obese men.
