    Abstract Chrononutrition (i.e., circadian timing of food intake) has been linked to indicators of health status such as body weight and insulin resistance. A measure of general chrononutrition patterns, the Chrononutrition Profile - Questionnaire, has been developed and preliminary evidence of validity and reliability of the measure has been documented in a homogenous group of undergraduates. However, this measure has not yet been validated in an online, community-based sample. The present study therefore aimed to evaluate the validity of the Chrononutrition Profile - Questionnaire in a web-based community sample. Analyses suggested that the Chrononutrition Profile - Questionnaire displays acceptable validity for use in diverse community samples of adults, with moderate to strong correlations (r = 0.39-0.91) between the Chrononutrition Profile - Questionnaire and measures of dietary intake and sleep. This measure is suitable for use in a variety of settings, by stakeholders and scientists, and may contribute to future development of health behavior interventions and research programs centered around chrononutrition.

    Abstract Background: Recent research has used the theory of planned behavior (TPB) to predict sleep. However, this research has focused on between-person effects and has failed to capture the intraindividual variability of sleep-related attitudes, subjective norms, perceived behavioral control, and intentions.
    Purpose: The current study sought to characterize the between- and within-day patterns of these constructs.
    Methods: Participants (N = 79) completed a 1 week ecological momentary assessment protocol in which they reported their attitudes, subjective norms, perceived behavioral control, and intentions toward nightly sleep opportunity four times per day.
    Results: Analyses revealed both between- and within-day variability of these constructs, with perceived behavioral control and intentions demonstrating greater variability than attitudes and subjective norms. Mixed linear models revealed that attitudes and subjective norms significantly increased throughout the week, while perceived behavioral control and intentions significantly decreased throughout the day.
    Conclusions: The between- and within-day patterns of the TPB constructs highlight important methodological considerations and provide insight into the potential refinement of sleep promotion efforts.

    Abstract Many American adolescents and adults report that they are not meeting sleep duration recommendations. Although insufficient sleep duration can occur due to factors outside an individual's direct control, many individuals choose to restrict their own sleep. The theory of planned behaviour (TPB) offers a framework to study this phenomenon. Recent research efforts have used the TPB to study sleep and have demonstrated success predicting sleep-related intentions and behaviour but have failed to consider volitional sleep behaviour or consider between- and within-person differences. The present study used an intensive longitudinal design to test how constructs of the TPB relate to nightly sleep opportunity. Healthy college students (N = 79) participated in a weeklong study in which they completed four ecological momentary assessment signals per day that measured their attitudes, subjective norms, perceived behavioural control, and intentions relating to their nocturnal sleep opportunity. Participants wore an actiwatch each night of the study to measure their sleep opportunity. Mixed linear models found that both intentions and perceived behavioural control were significant predictors of subsequent sleep opportunity, and that perceived behaviour control was the strongest within-day predictor of intentions. Results demonstrate that within-person changes in perceived behavioural control and intentions predict subsequent sleep opportunity and provide insight into the potential refinement of sleep promotion efforts.

    Abstract Both internal (e.g., preferences) and external (e.g., social) factors guide chrononutrition (i.e., the timing of food intake), but the nature and variability of chrononutrition preferences (i.e., preferred timing of food intake) have not been empirically evaluated. The present study aimed to characterize the variability and range of chrononutrition preferences and to evaluate the extent of eating misalignment, defined as the discrepancy between chrononutrition preferences and chrononutrition behaviors. 192 undergraduate students aged 18 to 31 years self-enrolled in an online questionnaire study. Participants provided demographic information and completed the Chrononutrition Profile - Questionnaire to evaluate chrononutrition preferences, chrononutrition behaviors, and eating misalignment. Results indicated high inter-individual variability in chrononutrition preferences and eating misalignment, with extreme cases of eating misalignment across all chrononutrition facets. This study is the first to confirm that when individuals

    Abstract The circadian timing of food intake (i.e., chrononutrition) has been linked to various markers of health status, such as body weight and insulin sensitivity. However, a valid assessment of day-to-day, within-person patterns in chrononutrition has not yet been developed. This paper details the development and initial validity testing of the Chrononutrition Profile - Diary (CP-D). The CP-D assesses 6 components of chrononutrition that are likely to influence health (breakfast skipping, largest meal, evening eating, evening latency, night eating, and eating window). This measure demonstrated preliminary evidence of convergent validity with the ASA24 (Automated Self-Administered 24-hour dietary assessment tool). The CP-D is designed for use by both healthcare professionals and researchers. It can serve as an independent assessment of day-to-day patterns of chrononutrition, and can also be used along with existing dietary measures to provide a comprehensive assessment of participants' and patients' daily eating behaviors and meal timing patterns.

    Abstract A significant proportion of the population is classified as having overweight or obesity. One framework which has attempted to explain biobehavioral mechanisms influencing the development of overweight and obesity is the energy balance model. According to this model, the body continually attempts to balance energy intake with energy expenditure. When energy intake and energy expenditure become imbalanced, there is an increase in homeostatic and allostatic pressure, generally to either increase energy intake or decrease energy expenditure, so as to restore energy homeostasis.Recent research has indicated that circadian aspects of energy intake and energy expenditure may influence energy balance. This paper provides a narrative review of existing evidence of the role of circadian timing on components of energy balance. Research on the timing of food intake, physical activity, and sleep indicates that unhealthy timing is likely to increase risk of weight gain. Public health guidelines focus on

    Abstract Background: Restricting daytime naps is a common sleep hygiene recommendation to improve nocturnal sleep, but research on whether napping is related to sleep is mixed. The current literature is limited in that day level, bidirectional associations have not been tested in college students, and existing studies have not sufficiently examined the role of individual differences in these daily associations.
    Purpose: The current study addressed these limitations by assessing the temporal associations between self-reported daytime nap duration and objectively assessed nocturnal sleep, and whether these associations were moderated by chronotype or nap frequency, in college students.
    Methods: Participants (N = 384) self-reported nap duration and wore an actiwatch to measure nocturnal sleep for 14 consecutive days and nights. Mixed linear models were used to test the daily associations between daytime nap duration and total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE), and wake after sleep onset (WASO). In addition, random slope modeling was used to test whether these associations significantly varied between participants.
    Results: Longer nap duration was significantly associated with greater WASO, lower SE, and longer SOL. Shorter TST, shorter WASO, and greater SE were related to longer next-day nap duration.
    Conclusions: There were several significant associations between daytime napping and nocturnal sleep, and nap frequency significantly moderated the association between TST and next-day nap duration. Future research should test daily and contextual moderators of daytime napping and nocturnal sleep, which could refine sleep hygiene efforts by identifying individuals for whom recommendations would be most helpful.

    Abstract Although sleep hygiene is often used for broad sleep health promotion efforts, sleep hygiene education programmes are largely ineffective. These programmes are limited by their lack of a theoretical foundation. Health behaviour theory (HBT) has been used for decades to successfully predict and modify many health behaviours, but its use in the study of sleep health is rare. The purpose of this review is threefold. First, four dominant HBTs will be introduced. Second, the brief literature on HBT and sleep health will be reviewed. Lastly, a translational research agenda will be proposed. The present review concludes that HBT shows potential in both the prediction and modification of sleep health, and that there are several short- and long- term research goals to advance these efforts.
