“…Adolescence (12 -17 years) is a critical period when a shift in CT is seen to occur from MT to a more pronounced tendency to ET (Achari & Pati, 2007;Borisenkov et al, 2010;Kim et al, 2002;Randler, 2008aRandler, , 2011Roenneberg et al, 2004;Russo et al, 2007;Tonetti et al, 2008).…”

“…However, studies with Asians participants do not find differences between adolescents and adults (Achari & Pati, 2007;Harada et al, 2011;Takao et al, 2009), and even the prevalence of sex is the opposite (Gaina et al, 2006). This might be due to biological differences (genetic and ocular photosensitivity) with respect to Caucasians (Tonetti et al, 2011).…”

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.

“…Los estudios realizados también apuntan a una mayor prevalencia de vespertinidad en los varones (Adan et al, 2012;Adan y Natale, 2002), los cuales además aportan una mayor amplitud de sus funciones circadianas (Adan y Sánchez-Turet, 2001), lo que se ha interpretado como una mayor potencia endóge-na rítmica menos dependiente de las señales externas. Otros factores que parecen afectar a la tipología circadiana son las variables ambientales, como el hábitat, el clima, la longitud y la latitud (Achari y Pati, 2007;Randler, 2008a).…”

Resumen: La tipología circadiana (matutina, vespertina o intermedia) es una diferencia individual que se ha relacionado con numerosos aspectos de la salud mental. En este estudio se revisan los principales hallazgos publicados en el área. Tras la búsqueda bibliográfica en las principales bases de datos se seleccionaron un total de 70 artículos publicados en castellano e inglés entre los años 1990 y 2012, recogidos en las bases de datos ISI, Scopus y Medline, donde se muestra que los individuos vespertinos presentan una mayor prevalencia de trastorno afectivo estacional, depresión mayor, trastorno bipolar, esquizofrenia, trastornos de la conducta alimentaria, trastornos del sueño, conductas adictivas, TDAH y mayores niveles de ansiedad que los matutinos. La tipología vespertina se perfila como un factor de riesgo y la matutina como un factor protector para el desarrollo de diversas psicopatologías, apuntándose como posibles causas polimorfismos de los genes reloj, el jet-lag social y algunos rasgos de personalidad. La tipología circadiana debe considerarse en la evaluación, tratamiento y prevención de las psicopatologías, pues afecta al inicio, curso, remisión y recaída de las mismas. La utilización de terapia cronobiológica es un factor a tener en cuenta en el abordaje terapéutico cuando la expresión rítmica circadiana se halla alterada. Palabras clave: revisión sistemática cualitativa; tipología circadiana; matutinidad-vespertinidad; salud mental; psicopatología. Title:Circadian typology and problems in mental health. Abstract: Circadian typology (morning-type, neither-type, and eveningtype) is an individual difference which has been related to numerous aspects of mental health. In this paper we present a review of the findings published on this topic. After searching in the main databases a total number of 70 works were selected, published in Spanish and English from 1990 to 2012 collected in the databases ISI, Scopus and Medline. These works show that individuals with evening-type typology exhibit a greater prevalence of seasonal affective disorder, mayor depression, bipolar disorder, schizophrenia, eating disorders, sleep disorders, addictive behaviours, ADHD, and higher anxiety levels than morning-type typology individuals. In this sense, the evening-type is considered as a factor of risk whereas the morning-type would be a protective factor for the development of several mental disorders. This could be a result of clock gene polymorphisms, social jet lag and some personality traits. Circadian typology must be considered in the evaluation, treatment and prevention of the mental disorders, as it affects to the start, course, remission and relapse of diverse problems of mental health. Chronobiological therapy must be also considered in the therapeutic approaching when the circadian rhythmical expression is altered. Key words: qualitative systematic review; circadian typology; morningnesseveningness; mental health; psychopathology.

“…The chronotypological studies reliably detect age trend of morningness-eveningness score (i.e., Tankova et al 1994;Carrier et al 1997;Steele et al 1997;Giannotti et al 2002;Paine et al 2006;Achari and Pati 2007). However, significant differences between male and female scores were reported only in a minor part of the investigations which disagree on the question of which gender is more morning-oriented (Ishihara et al 1988;Steele et al 1997;Harada and Inoue 1999;Adan and Natale 2002;Natale et al 2002;Gaina et al 2006;Achari and Pati 2007). Such absence of marked unidirectional difference between genders contradicts with the objective measurements of circadian rhythms that often reveal an earlier circadian phase in women (see for review Tankova et al 1994).…”

Studies of morning-evening preference consistently recognize age differences, but gender differences are rarely reported. To examine these differences, we applied the Sleep-Wake Pattern Assessment Questionnaire (Putilov 1990(Putilov , 2000(Putilov , 2007. Unlike unidimensional morningness-eveningness scales, it includes separate scales for the measurement of Evening and Morning lateness (E and M, respectively). Data on 7465 adolescents and adults suggest that both E and M scores significantly decline with age. Genders are identical on the sum of E and M scores, but female respondents of any age cohort have a lower E score and a higher M score. Differences between these scores remain constant across ages. Analysis of a subset of data on 2016 adults revealed significant correlation of this difference with self-reported sleep length which, however, is not significantly longer in women. We concluded that, compared to men, women prefer earlier bedtimes and later wake up times and can desire but not obtain more sleep.
