Morningness-eveningness and sleep habits among adolescents: age and gender differences

Previous research has indicated the need to use large samples in different cultural contexts in order to clarify age and gender differences on morningness-eveningness and sleep habits. The goal of our research was to study the relationship between morningness-eveningness and sleep habits in a large sample of 2,649 adolescents between 12 and 16 years. The Morningness- Eveningness Scale for Children and an adaptation of the School Sleep Habits Survey measures were used. Results indicated a greater tendency toward eveningness with age and higher eveningness in 13- and 14-year-old girls. Older adolescents claimed later rising time on weekends, later bedtime and shorter sleep length, and greater social jetlag, weekend rise time delay, and weekend bedtime delay. Girls reported earlier rising time on weekdays, later rising time on weekends, longer sleep length on weekends, and greater social jetlag and weekend rising time delay. Lastly, evening oriented adolescents claimed later rising time and bedtime, shorter sleep length on weekdays but longer sleep duration on weekends, and greater social jetlag, weekend rising time delay, and weekend bedtime delay.

Perspectiva temporal futura y ciclo vital

This study described the future temporal perspective (FTP) changes across age. Future time perspective has been evaluated according to Nurmi’s model (1989), which was composed by three components: motivation, planning, and prospective evaluation. The participants were four groups of different ages: 130 adolescents (15-18 years old), 150 undergraduates (19-28 years old), 100 adults middle age (30-59 years old), and 74 elder people (60-88 years old). It has been used the Nurmi’s Goals and Fears Questionnaire, which evaluated each three component through temporal extension, knowledge, realization, planning, control, probability of fu-ture realization, and future affect dimensions. It has been analysed dimensions for goals and fears. The results indicated a U inverted shape in tem-poral distance, progressive increase of knowledge, realization and planning, and decrease of control. Also, the results indicated gender differences according to content of goals and fears.

Time Trends in Self-Rated Health and Disability in Older Spanish People: Differences by Gender and Age

Abstract Background: To analyse time trends in self-rated health in older people by gender and age and examine disability in the time trends of self-rated health. Methods: The data used come from the Spanish National Health Surveys conducted in 2001, 2003, 2006 and 2011- 12. Samples of adults aged 16 yr and older were selected. Multivariate logistic regression was used to assess the association between age, gender, socio-economic status, marital status, disability and self-rated health across period study. Results: Women exhibited lower (higher) prevalence of good self-rated health (disability) compared to men. The multivariate analysis for time trends found that good self-rated health increased from 2001 to 2012. Overall, variables associated with a lower likelihood of good self-rated health were: being married or living with a partner, lower educational level, and disability. Conclusion: Trends of good self-rated health differ by gender according to socio-demographic factors and the prevalence of disability.
