Abstract
This study aimed to analyze the association between the duration of the nap and the variables gender, age, education, family income, frailty levels and frailty criteria of community-dwelling elderly. This was a descriptive and cross-sectional study, an excerpt from the multicenter project Frailty in Elderly Brazilians. A total of 3,075 older adults were evaluated, aged 65 and over, using a sociodemographic questionnaire, question about nap (Minnesota Leisure Activity Questionnaire), phenotype of frailty proposed by Fried and screening test for cognitive impairment (Mini Mental State Examination). Descriptive analysis, Mann-Whitney and Kruskal-Wallis tests (p<0.05) and multiple linear regression were applied. Ethical principles were respected. Most of the elderly participants napped (61.7%), with an average of 53.4±42.7 min/day. There was an association between duration of naps and variables gender (p=0.002), frailty (p=0.022) and frailty criterion "hand grip strength" (p=0.008). It was observed that the length of the naps is greater for male and frail elderly.
Highlights
Napping can be defined as a short rest period during which the activity decreases and the reactions to external stimuli are reduced.[1]
Researchers affirm that frequent, unplanned and lengthy (90 minutes or more) daily napping can negatively affect the quality of nighttime sleep and may be associated with negative consequences for health, such as increased risk of morbidity, cardiovascular disease, falls and cognitive problems.[4,5]

Summary
Napping can be defined as a short rest period during which the activity decreases and the reactions to external stimuli are reduced.[1]. Researchers affirm that frequent, unplanned and lengthy (90 minutes or more) daily napping can negatively affect the quality of nighttime sleep and may be associated with negative consequences for health, such as increased risk of morbidity, cardiovascular disease, falls and cognitive problems.[4,5]. In contrast with these negative effects, short daily naps can demonstrate positive effects. It can be considered an important stress coping mechanism and have a beneficial effect.[6]
