“…In our study, apathy was also correlated with the number and duration of naps, as suggested in Muller's study, such that those with apathy had higher mean duration of daytime napping. 29 As such, although there is good evidence that daytime inactivity can be considered a marker of apathy, there is insufficient evidence to conclude that apathy is associated with increased daytime napping. 28 Actigraphy is, in fact, quite poor at discriminating daytime napping (i.e., immobility on a background of movement) from quiet wakefulness.…”

“…The differences are attributable at least in part, to developmental changes in the mechanisms regulating sleep timing (Dahl et al, 1995). There is a trend for individuals to become more morning type in later adulthood (Gander et al, 2004) (Dumont and Carrier, 1997), typically beginning at around age 50 years (Torsvall and Akerstedt, 1980); (Bliwise et al, 2005). Our observations using the Hindi version of the CSM are consistent with these observations (Diaz-Morales and Gutierrez Sorroche, 2008).…”

Background Several pen and paper measures of human circadian preference are available in English, but none are available in Hindi, hampering research in circadian behavior among Hindi speaking populations in India and elsewhere. The present study describes a Hindi version of the Composite Scale of Morningness (CSM), a self reported questionnaire widely used to assess morningness/eveningness (M/E). M/E has been used a proxy for circadian phase in lieu of cumbersome and expensive laboratory studies. Method The thirteen item English version of the CSM was translated into Hindi and independently back translated into English. Inconsistencies between the original and back translated versions were then resolved. Both versions were next administered to bilingual persons at Delhi, India (N = 130). After intra-class correlations between the Hindi and the English versions were examined, the Hindi version was administered to community based participants representing different age groups (N = 310). Results There was satisfactory intra-class correlation (ICC) between the total scores for the Hindi and the English versions of the CSM (Cronbach’s alpha = 0.873), with variation for individual items scores. Total CSM scores in the second sample suggested a significant association with age, consistent with published reports with the English CSM, i.e., morningness tendencies were more likely to be reported by older adults. Significant associations with gender or educational status were not observed. Conclusions The Hindi CSM is a brief questionnaire that provides behavioral measures of diurnal preference. It is freely available for research in Hindi speaking populations.

“…We assessed sleep duration and quality using two approaches: a standard sleep log used by the Emory Program in Sleep, Aging, and Chronobiology 18 and a conventional questionnaire to measure sleep quality, ie, the Pittsburgh Sleep Quality Index. 19 The sleep log collected daily data on total sleep time.…”

Background:The metabolic syndrome is a constellation of interrelated metabolic risk factors that appear to increase the risk of atherosclerotic cardiovascular disease, type 2 diabetes mellitus, and possibly some cancers. Animal studies and observational clinical data in humans suggest that supplemental melatonin may ameliorate a number of components of the metabolic syndrome, including elevated glucose, elevated blood pressure, dyslipidemia, and obesity. The primary objective of this clinical trial was to determine the feasibility, efficacy, and safety of melatonin supplementation in men and women with the metabolic syndrome. Methods: Thirty-nine men and women of mixed race/ethnicity were enrolled into a randomized, double-blind, placebo-controlled clinical trial with two arms: placebo for 10 weeks followed by melatonin for 10 weeks, or vice versa, with an interval 6-week washout period, in a crossover trial design. Outcome measures include metabolic syndrome components (blood pressure, glucose, triglycerides, high-density lipoprotein cholesterol, waist circumference), oxidative stress, and inflammation biomarkers. These biomarkers, along with sleep duration and quality and pretreatment endogenous melatonin levels, were measured to explore possible underlying biologic mechanisms. Discussion: This trial will provide knowledge of the effects of melatonin in metabolic syndrome subjects, and lay the groundwork for future clinical trials of melatonin in metabolic syndrome subjects.

Age Changes in Timing and 24-Hour Distribution of Self-Reported Sleep

Abstract: These results confirm previous cross-sectional studies and suggest a complex biopsychosocial matrix for the timing and placement of sleep in elderly persons within the 24-hour day.
