Much of this evidence comes from sleep labs in the developed world, where sleep can be carefully manipulated, and short-run physiological and cognitive outcomes precisely measured. In contrast, there is much less knowledge about how sleep deprivation affects the health of individuals in the developing world, coming from a lack of studies outside the lab and over longer periods. This project aims to fill this gap. The investigators will implement a randomized controlled trial (RCT) with 450 low-income adults in Chennai, India, providing the first objective measurement of sleep in a developing country. The investigators will also evaluate scalable interventions to improve the sleep of poor adults, such as providing home sleep-aid devices and a comfortable space for a 30-minute afternoon nap at the participants' work site. Finally, the study aims to assess the impact of improved sleep on health, with a primary focus on cardiovascular health and cognitive outcomes."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '25 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Unemployed and underemployed adult men and women of working age (see previous age limit) who have worked less than 5 days per week over the last month and earned less than Rs. 700 per day over that same period.\n* Participants must live in Government board house or in a house with some kind of roof that protect the sleep aids from rain, such as a concrete or a metal or a Tarpaulin, ... roof.\n* Have limited experience with typing, and limited knowledge of English.\n* Participants need to speak Tamil, the local language, to be able to write numbers and to be able to commit easily to the office.\n\nExclusion Criteria:\n\n* Participants who cannot commit to come to the office for the duration of the whole study.\n* Participants who own more than three of the sleep aids that we provide in our sleep kit.\n* Participants who have previously participated in the sleep study.\n* Participants who have children younger than three years old.'}, 'identificationModule': {'nctId': 'NCT03322358', 'briefTitle': 'Chronic Sleep Deprivation Among the Poor: A Lab-in-the-field Approach', 'organization': {'class': 'OTHER', 'fullName': 'University of Pennsylvania'}, 'officialTitle': 'Chronic Sleep Deprivation Among the Poor: A Lab-in-the-field Approach', 'orgStudyIdInfo': {'id': '14-2294'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'NO_INTERVENTION', 'label': 'Control', 'description': 'No changes to normal sleep habits.'}, {'type': 'EXPERIMENTAL', 'label': 'Naps only', 'description': 'After a baseline period, participants in this condition will be provided with the opportunity to nap in a quiet comfortable "nap cabin" in the study office for 30 minutes each afternoon on all work days.', 'interventionNames': ['Other: Naps']}, {'type': 'EXPERIMENTAL', 'label': 'Home sleep aids only', 'description': 'After a baseline period, participants in this condition will be provided with a set of home sleep aids (e.g. earplugs, eyeshades, a basic mattress, sheets, and pillow, etc) to take home with them if they wish.
