ABSTRACT
Social-economic factors influence sleep habits. This research analyzes characteristics of nocturnal sleep in Brazilian Native Terena adults. Sixty-four adults (31 M; 33 F) from 18 to 75 years, with a mean age of 37.0, from the Indian Reservation village of Córrego do Meio, in the central region of Mato Grosso do Sul, an agriculturally oriented group were evaluated. Nocturnal sleep characteristics were evaluated by means of a standard questionnaire applied to each individual. It was observed that reported nocturnal sleep was longer, sleep onset was earlier and wake up time was also earlier than usually described in urban populations. The mean total time in bed was 8.5 h or more, in every age bracket. The seven-day prevalence rate of insomnia was 4.6 por cento, while the seven-day prevalence rate of hypnotic use was 1.5 por cento, both remarkably less than described in urban populations. These findings stress the need to consider ethnic influences on sleep patterns and disorders.

Regular daytime napping behavior, also known as siesta culture, is influenced by circadian, cultural and environmental factors. This research analyzes characteristics of regular daytime napping in Brazilian Native Terenas. We evaluared 65 adults ( 32 M; 33 F ) from 18 to 75 years, with a mean age of 37.2, from the Indian Reservation village Córrego do Meio, in the central region of Mato Grosso do Sul. Daytime napping characteristics were evaluated by means of a standard questionnaire applied to each individual. It was observed that weekly daytime napping (at least once a week) was present in 72.3 per cent of the population. There was a tendency to occur in males. The effects of weekends was mild. Mean onset time of daytime sleep was 12.2 h, remarkably earlier than usually described in urban populations. This data stresses the need to consider ethnic influences in order to understand sleep habits.

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 reumained 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 per cent of the 2-3 year olds; decreasing to 25.0 per cent of the 8-10 years olds. Only 5.4 per cent of the children slept alone in their own bedroom. Mean number of persons per bedroom was 2.8. Only 7.0 per cent of the bedrooms had TV; 98.1 per cent slept in silence. The data obtained support the need to weigh cultural factors influence on sleep.

Sleep behavior patterns in childhood are influenced by familial, cultural and environmental factors. In understanding sleep in Native Brazilian Bororo children, one should consider the influence of their culture on the child's sleep. This research analyzes sleep habits of Native Bororo children from the Meruri village, located in an Indian Reservation in the state of Mato Grosso. Fourty four children (24 M; 20 F) were evaluated, ages ranged from one month to 10 years, with a mean age of 4.9 years. Sleep characteristics were assessed by means of a standard questionnaire applied to the mothers. Cosleeping - sleeping together with family members - was a remarkable finding, in every child 0-2 year old and in 81.5 per cent in the 2-10 years group. The second characteristic was sleeping with many people in the same room. There was an average of 5.1 people per room in the younger group and 3.9 people in the older group.
