-Developmental and cultural factors affect sleep habits in childhood. The objective of this research was to determine sleep habits of children in the isolated rural African-Brazilian community of Furnas do Dionísio, Mato Grosso do Sul, Brazil. The members of this community are closely related descendants of the ex-slave Dionísio, and remained in relative geographical isolation for about a century. Sleep characteristics of 55 children (35M; 20F), 2 to 10 year olds, were evaluated in interviews with their mothers. The results showed that cosleeping, in the same bed with family members, was present in 80.0% of the 2-3 year olds; decreasing to 25.0% of the 8-10 year olds. Only 5.4% of the children slept alone in their own bedroom. Mean number of persons per bedroom was 2.8. Only 7.0% of the bedrooms had TV; 98.1% slept in silence. The data obtained support the need to weigh cultural factors influence on sleep.KEY WORDS: sleep, sleep habits, child, African-Brazilian, Negro, Black, Furnas do Dionísio, Mato Grosso do Sul. Características do sono da criança na comunidade negra rural isolada de Furnas do Dionísio no Mato Grosso do SulRESUMO -Hábitos de dormir da criança sofrem influências fisiológicas e culturais. O objetivo desta pesquisa foi verificar os hábitos de dormir da criança da comunidade negra rural e isolada de Furnas do Dionísio, no Mato Grosso do Sul. A comunidade é composta dos membros de uma mesma família, descendentes do ex-escravo Dionísio, mantida por cerca de um século em isolamento geográfico relativo. As características de 55 crianças (35 M; 20 F), de 2 a 10 anos de idade, foram pesquisadas através de entrevistas com as mães. Resultou que o hábito de dormir junto (cosleeping) estava presente em 80,0 % aos 2-3 anos; reduzindo a 25,0 % aos 8-10 anos. Apenas 5,4% dormiam sozinhas em seu quarto. A média de pessoas por quarto foi 2,8. Apenas 7,0 % dos quartos tinham televisão; 98,1% eram silenciosos. Os resultados apóiam a necessidade de determinar a influência de fatores étnicos no sono.

“…Among 2 and 3 years old, African-Brazilian children 80% s h are the bed until 10 years old. We found the same habits among the indigenous population of Terena and B o ro ro, children sharing the bed with their pare n t s are a remarkable characteristic of this society [17][18][19] . This study aims to verify the sleep habits of 7 to 10 years old children in São Paulo City, Brazil, o b s e rving their evolution according to age, gender and s t a rting time to school.…”

Milk drinking before sleep was more frequent among seven years old children. We found a progressive reduction with age in keeping the lights on. Girls used to leave an object to bed more than boys did. Children that studied in the morning presented reduced total sleep time, sleep earlier, and nap more frequently than children that studied in the afternoon. Conclusion. Starting time to school deeply influences sleep habits in Brazilian children from São Paulo City, in whom bed-time rituals are highly prevalent.KEY WORDS: sleep habits, nap, total sleep time, bed-time, starting time to school, children.

The ballance between endogenous and exogenous factors is remarkably relevant for biological rhythms, and it can be impaired by environmental changes and consequently provoke a series of disturbances such as sleep disorders, indisposition, gastro-intestinal changes 1 , mood fluctuations, irritability, tension, confusion, anxiety and reduced performance in tasks that require attention and concentration 2 . The sleep-wakefulness cycle is a circadian rhythm that, under natural conditions oscillates over a 24-hour period. The interchange of day-night (lightdark), school hours, work hours, leisure time, family activities, are exogenous factors that synchronize sleep-wakefulness 3 . Besides this environmental synchronization, the sleep-wakefulness cycle originates and is regulated endogenously by a neural structure located in the hypothalamus, it is the supraquiasmatic nucleus, considered the master circadian biological clock for mamals 4,5 . Optional hours, that prevent us from sleeping at habitual hours, considerably affect psychophysiological balance. The clinical adverse effects of the interruption of circadian rhythms, such as night-shift work include severe impairment during wakefulness 1 . Sleep is an important factor of synchronization between internal fluctuations and environmental cycles. In humans, the best example of organism and environmental synchronization is the sleep/ wake cycle, regulated by light and dark. According to their nature and social organization, human are active during the day, their physical functions are es- NIGHTLY USE OF COMPUTER BY ADOLESCENTSIts effect on quality of sleep
