This study aimed to verify if girls are at a higher risk to present sleep problems and if associations of a sleep perception are different between sexes even when accounting for biological maturation. Participants were adolescents girls , mean age Participants' socio-demographic characteristics included sex, age, school grade, father and mother education; besides participants were inquired about sleep duration and characteristics of their sleep quality. The most prevalent characteristics of poor sleep quality were waking up tired Overall, girls presented a poorer sleep health with low quality and quantity of sleep. Furthermore, associations of an enough and good sleep were different between boys and girls, even when controlling for the impact of delayed pubertal maturity.
Sleep in adolescence: sex matters?
To formulate the first classification of sleep related disorders and abnormal sexual behaviors and experiences. A computerized literature search was conducted, and other sources, such as textbooks, were searched. Kleine-Levin syndrome 78 cases and parasomnias 31 cases were most frequently reported. Parasomnias and sleep related seizures had overlapping and divergent clinical features. Thirty-one cases of parasomnias 25 males; mean age, 32 years and 7 cases of sleep related seizures 4 males; mean age, 38 years were identified. Forensic consequences were common, occurring in All parasomnias cases reported amnesia for the sleepsex, in contrast to
Patterns of female sexual arousal during sleep and waking: Vaginal thermo-conductance studies
The main objective of this investigation was to ascertain whether there are, in the female, periods of sexual excitation or arousal during REM sleep similar to the cycle of penile erections in the male. In a group of 10 subjects, 21—35, utilizing a thermoconductance method that gives a measure of vaginal blood flow VBF , we are able to confirm that females manifest cyclic episodes of vascular engorgement during REMPs equivalent to erections in men. The increases in VBF, in terms of rises of the recording pen on the graph paper, varied from 10 to 45 mm. In order to ascertain the significance of these increases, we compared these sleep responses with waking VBF responses evoked by nonerotic and erotic stimuli and by masturbation. Only erotic stimuli gave VBF responses, the greatest to the movie and masturbation; these were no greater than the maximum levels attained during sleep, namely 40 to 45 mm.
To assess the relationship between sex and the development of sleep patterns in adolescents from grade 7 to We analyzed longitudinal data from annual school-based assessments of sleep habits among secondary school students in northern Taiwan. Measures of sleep patterns included sleep length on weekdays and weekends as well as weekend—weekday difference WndD , defined as the discrepancy in the time in bed TIB between weekdays and weekends. Growth curve models were used to assess sex differences in sleep patterns. Associations between other covariates and sleep patterns were also explored.
