“…ET subjects reported higher consumption -sporadic and habitual-of the three substances. Subsequent international studies have confirmed this observation, and this is of special relevance for adolescent and adult 30 populations (Andershed, 2005;Gau et al, 2007;Urbán et al, 2011;Giannotti et al, 2002;Wittmann et al, 2006). Prat & Adan (2011) have also found ET subjects consumed more illegal drugs (cannabis, ecstasy and cocaine) and hazardous alcohol use than MT.…”

The interest in the systematic study of the circadian typology (CT) is relatively recent and has developed rapidly in the two last decades. All the existing data suggest that this individual difference affects our biological and psychological functioning, not only in health, but also in disease. In the present study, we review the current literature concerning the psychometric properties and validity of CT measures as well as individual, environmental and genetic factors that influence the CT. We present a brief overview of the biological markers that are used to define differences between CT groups (sleep-wake cycle, body temperature, cortisol, and melatonin), and we assess the implications for CT and adjustment to shift work and jet-lag. We also review the differences between CT in terms of cognitive abilities, personality traits and the incidence of psychiatric disorders. When necessary, we have emphasized the methodological limitations that exist today and suggested some future avenues of work in order to overcome these. This is a new field of interest to professionals in many different areas (research, labor, academic, and clinical) and this review provides a state of the art discussion to allow professionals to integrate chronobiological aspects of human behavior into their daily practice.

“…20 According to the literature, M-type individuals wake up early in the morning, fall asleep at an early hour and prefer early morning activities, while E-types seem to have problems waking up in the morning (e.g., need to be waked up by parents), 20,21 staying awake during the day (especially during school time), and feeling more exhausted during the day. 20,22 Circadian preference changes from preadolescence and adolescence, when a consistent shift to evening preference has been reported. 21 As a consequence, adolescents' sleep is characterized by later bedtimes and later rising times.…”

Study Objectives: The purpose of this study was to analyze differences between preadolescents and adolescents on the use of technology and to test the contribution of using Internet and mobile phone, and circadian preference on sleep quality. Methods: We recruited a sample of 850 (364 males) preadolescents and adolescents. Self-report questionnaires about sleep schedule, sleep wake behavior problems, circadian preferences, and the use of technology (e.g., Internet and mobile phone) were administered. Students were asked to fi ll out the School Sleep Habits Survey, a self-report questionnaire on the use of technology, the Mobile Phone Involvement Questionnaire (MPIQ), and the Shorter Promis Questionnaire (SPQ). Results: Adolescents reported more sleep problems, a tendency toward eveningness, and an increase of Internet and phone activities, as well as social network activities, while preadolescents were more involved in gaming console and television viewing. The regression analysis performed separately in the two age groups showed that sleep quality was affected by the circadian preference (eveningness) in both groups. Adolescents' bad sleep quality was consistently associated with the mobile phone use and number of devices in the bedroom, while in preadolescents, with Internet use and turning-off time.

“…Trabajos posteriores desarrollados en diversos países han confirmado la observación, siendo ello de especial relevancia en población adolescente (Andershed, 2005;Gau, Shang, Merikangas, Chiu, Soong y Cheng, 2007). Mientras que la tipología circadiana matutina parece ser un factor protector en el inicio y mantenimiento de consumo de drogas, la tipología vespertina puede considerarse un factor de riesgo.…”

The chronobiological aspects of addiction constitute a recently developed field of study that has obtained interesting data from both ibasic and clinical research. Drug consumption has a negative effect on the expression of circadian rhythmicity, since it produces a flattening of the functions and a delay of maximal values, and can even cause a state of desynchronization of endogenous control. Moreover, it has been shown that the clock-genes Clock and Per2 are associated with vulnerability to addiction, the first gene directly regulating dopaminergic activity in the reward system and the second participating in the sensitivity to and abstinence from drugs. The evening circadian typology has also been proposed as an individual difference to be taken into account as a risk factor in the development of drug addiction. Finally, the reorganization of circadian rhythmicity with regular daily schedules adjusted to the cycle of light-darkness, exposure to natural or artificial light, and the administration of melatonin may be useful strategies in the treatment of drug addictions.Key words: chronobiology; circadian rhythmicity; clock genes; circadian typology; melatonin; bright light. RESUMEN ABSTRACTEl estudio de los aspectos cronobiológicos relacionados con la adicción es un campo de reciente desarrollo que ha recabado datos tanto básicos como clínicos de interés. El consumo de drogas afecta negativamente la expresión rítmica circadiana, produciendo un aplanamiento de las funciones y un retraso de los valores máximos, pudiendo incluso desembocar en un estado de desincronización del control endógeno. Además, los genes reloj Clock y Clock y Clock Per2 se han mostrado asociados con la vulnerabilidad a la adicción, el primero regulando directamente la actividad dopaminérgica en el sistema de la recompensa y el segundo participando en la sensibilidad y abstinencia a las drogas. La tipología circadiana vespertina también se ha perfilado como una diferencia individual a tener en cuenta como factor de riesgo en el desarrollo de adicción a drogas. Finalmente, la reorganización de la ritmicidad circadiana con hábitos horarios regulares ajustados al ciclo luzoscuridad, la exposición a luz natural o artificial y la administración de melatonina pueden ser estrategias a utilizar en el tratamiento de las drogodependencias.
