Abstract Introduction Few studies have examined circadian phase after job loss, an event that upends daily routine. It is common that a daily routine begins with the consumption of breakfast, and breakfast behavior may contribute to health status in adults. Therefore, we sought to examine whether a later midpoint of sleep was associated with breakfast skipping among adults whose schedules were no longer dictated by employment. Methods Data were obtained from the Assessing Daily Activity Patterns Through Occupational Transitions (ADAPT) study. The sample of 155 participants had involuntarily lost their jobs in the last 90 days. Both cross-sectional and 18-month longitudinal analyses assessed the relationship between sleep midpoint after job loss and current and later breakfast skipping. Assessment periods were 14 days. Sleep was measured via actigraphy, and breakfast skipping was measured via daily diary (1 = had breakfast; 0 = did not have breakfast). The midpoint of sleep was calculated as the circular center based on actigraphy sleep onset and offset times. Results The midpoint of sleep at baseline was negatively associated with breakfast consumption at baseline (B = -.09, SE = .02, p = .000). Also, a later midpoint was associated with breakfast skipping over the next 18 months (estimate = -.08; SE = .02; p = .000). Prospective findings remained significant when adjusting for gender, ethnicity, age, perceived stress, body mass index (BMI), education, and reemployment over time. Education (estimate = 14.26, SE = 6.23, p < .05) and BMI (estimate = -.51, SE = .25, p < .05) were the only significant covariates. No other sleep indices predicted breakfast behavior cross-sectionally or prospectively. Conclusion Consistent with research in adolescents, unemployed adults with a later circadian phase are more likely to skip breakfast more often. Breakfast skipping was also associated with higher BMI. Taken together, these findings provide support for the future testing of sleep/wake scheduling interventions to modify breakfast skipping and potentially mitigate weight gain after job loss.

Abstract Background In older adults, the linkage between laboratory-assessed ‘motor capacity’ and ‘mobility performance’ during daily routine is controversial. Understanding factors moderating this relationship could help developing more valid assessment as well as intervention approaches. We investigated whether the association between capacity and performance becomes evident with transition into frailty, that is, whether frailty status moderates their association. Methods We conducted a cross-sectional analysis of the observational Arizona Frailty Cohort Study (ClinicalTrials.gov identifier: NCT01880229) in a community-dwelling cohort in Tucson, Arizona. Participants were N = 112 older adults aged 65 years or older who were categorized as non-frail (n = 40), pre-frail (n = 53) or frail (n = 19) based on the Fried frailty index. Motor capacity was quantified as normal (NWS) and fast walking speed (FWS). Mobility performance was quantified as 1) cumulated physical activity (PA) time and 2) everyday walking performance (average steps per walking bout; maximal number of steps in one walking bout), measured by a motion sensor over a 48 h period. Hierarchical linear regression analyses were performed to evaluate moderation effects. Results Unlike in non-frail persons, the relationship between motor capacity and mobility performance was evident in pre-frail and frail persons, confirming our hypothesis. A moderating effect of frailty status was found for 1) the relationship between both NWS and FWS and maximal number of steps in one bout and 2) NWS and the average steps per bout. No moderation was found for the association between NWS and FWS with cumulated PA. Conclusion In pre-frail and frail persons, motor capacity is associated with everyday walking performance, indicating that functional capacity seems to better represent mobility performance in this impaired population. The limited relationship found in non-frail persons suggests that other factors account for their mobility performance. Our findings may help to inform tailored assessment approaches and interventions taking into consideration a person’s frailty status.

The Relationship

To investigate the relationship between circadian rhythms of body temperature and sleep-wake stages, four squirrel monkeys were prepared for unrestrained monitoring of temperature, locomotor activity, electroencephalogram, electroculogram, and electromyogram. Continuous records for each animal were made for several 12-h light-dark (LD) cycles and then after a few days in constant illumination (LL). All animals maintained consolidated sleep-wake cycles and had a longer circadian period (mean 24.7 h) in LL than in LD (mean 24.1 h). The increased period reflected greater time per circadian cycle spent awake in LL (mean 14.0 h) than in LD (mean 12.8 h). Total night NREM sleep was less in LL (mean 6.5 h) than in LD (mean 8.2 h). Sleep onset occurred at later phases in LL (187 +/- 6 degrees) than in LD (170 +/- 2 degrees). Because the circadian phase measure of NREM sleep was unchanged between LD and LL conditions, the difference in sleep onsets reflected balanced changes in NREM circadian waveforms. Wake-up phases were the same in both conditions (mean 342 degrees). In summary, during free run squirrel monkeys maintain a stable consolidated circadian sleep-wake cycle with a period greater than 24 h, but they exhibit only minimal internal phase restructuring.

Abstract Introduction Involuntary job loss is an acute stressor that disrupts daily time structure and activity and exacerbates economic hardship and psychological distress. Studies show that unemployment is associated with negative obesity-related health outcomes, such as metabolic syndrome. However, very little is known about daily routine, depression, and obesity in individuals who have recently experienced involuntary job loss. We hypothesized that individuals with less consistent daily routines, or unstable social rhythms, after job-loss would have more abdominal adiposity than individuals with more consistent social rhythms. We also hypothesized that this relationship would vary as a function of depressive symptoms. Methods Cross-sectional baseline data (n = 186) from the ongoing ADAPT study (Assessing Daily Activity Patterns through occupational Transitions) were analyzed using linear regression techniques. Participants were predominantly female (62%) with a mean age of 41.12 years (SD = 10.16 years); 31% were Hispanic or Latino. Over two weeks, participants completed the daily Social Rhythm Metric-17 (SRM), Beck Depression Inventory II (BDI), and waist circumference (adiposity) measurements (cm). Results A significant BDI x SRM interaction was detected in the prediction of waist circumference, B = .36, SE = .18, <i> p </i> < .05, 95% CI [.002, .709], R2 = .07). The SRM was inversely associated with waist circumference, B = -5.57, SE = 2.25, <i> p </i> < .05, 95% CI [-9.98, -1.13], only at lower levels of BDI (-1 SD below the mean). Results from the Johnson-Neyman technique identified that the conditional effect of SRM on waist circumference was statistically significant at a BDI raw score of 8.33 (0-13 points is minimal depression) with ~45% of cases within this region. Conclusion A less consistent daily routine was associated with a larger waist circumference among individuals with minimal depressive symptoms. These findings are the first to demonstrate a relationship between social rhythm stability and abdominal adiposity in adults at high risk for central obesity. Results highlight the moderating role of depression in obesity prevention. Future prospective analysis is necessary to examine causal pathways. Support #1R01HL117995-01A1

The Relationship

Involuntary job loss during the COVID-19 pandemic adds challenges, especially for custodial grandparents that are taking care of grandchildren. Grandparents are relatively vulnerable, and they need more attention and support when facing the negative impacts of COVID-19. This study analyzed cross-sectional survey data collected from 234 custodial grandparents via Qualtrics Panels in June 2020 in the United States. After using the propensity score weighting adjustment, results from logistic and ordinary least squares regression showed that compared with grandparents that did not lose their job during the pandemic, grandparents that did had more parenting stress and worse mental health. Moderation analysis also showed that social support was a significant moderator of the relationship between job loss and mental health, but not the relationship between job loss and parenting stress. The findings and implications are discussed.

Background:The aim of this study was to assess physical activity (PA) patterns (intensity and prevalence) in children according to demographic, socioeconomic, and familiar characteristics.Methods:In 2010, a cross-sectional study of 239 children aged 4–11 was conducted, in Pelotas, Southern Brazil. PA was measured by accelerometry and classified in different intensities. Insufficient physical activity was defined as less than 60 min/day of moderate-to-vigorous PA. Descriptive analyses of accelerometry-related variables were presented. Multivariate Poisson regression models were used to estimate the association between physical insufficient PA and covariates.Results:For both sexes, around 65% of the registered time was spent in sedentary activities and less than 20 min/day in vigorous activity. Age and economic status were inversely associated to PA in all categories of PA. Moderate and vigorous activities means were higher in boys than in girls. The prevalence of insufficient PA was 34.5% in girls and 19.5% in boys.Conclusions:We found important differences in physical activity patterns according to sex and economic status, as well as a significant decline in time spent in moderate-to-vigorous PA with increasing age. Understanding the relationship between these sociodemographic factors is important to tackle low levels of PA.

BACKGROUND The use of technology and social media among adolescents are an increasingly prevalent phenomenon. However, there is a paucity of evidence on the relationship between frequency of the use of electronic devices and social media and sleep-onset difficulties among the Italian population. OBJECTIVE The aim of this study is to investigate the association between the use of technology and social media, including Facebook and YouTube, and sleep-onset difficulties among adolescents from Lombardy, the most populous region in Italy. METHODS The relationship between use of technology and social media, and sleep-onset difficulties was investigated. Data came from the 2013-2014 wave of the Health Behavior in School-aged Children (HBSC) survey, a school-based cross-sectional study conducted on 3172 adolescents aged 11 to 15 years in Northern Italy. Information was collected on difficulties in falling asleep over the last 6 months. We estimated the odds ratios (OR) for sleep-onset difficulties and corresponding 95% confidence intervals (CI), using logistic regression models after adjustment for major potential confounders. RESULTS The percentage of adolescents with sleep-onset difficulties were 34.3% overall, 29.7% in boys and 39.2% in girls. It was 30.3% in 11yo, 36.2% in 13yo and 37.3% in 15yo adolescents. Sleep onset difficulties were more frequent among adolescents with higher use of electronic device: for general use (OR for highest vs lowest tertile of use= 1.50; 95% CI: 1.21-1.85); use for playing games (OR= 1.35; 95% CI: 1.11-1.64); use of online social network (OR for always vs never or rarely= 1.40; 95% CI: 1.09-1.81); and YouTube (OR= 2.00; 95% CI: 1.50-2.66). CONCLUSIONS This study adds novel information about the relationship between sleep-onset difficulties and technology and social media in a representative sample of school-aged children from a geographical location that has not been included in studies of this type previously. Exposure to screen-based devices and online social media is significantly associated with adolescent sleep onset-difficulties. Interventions to create a well-coordinated parent and school centered strategy, thereby increasing awareness on the unfavorable effect of evolving technologies on sleep among adolescents are needed.

Avoiding food before bedtime is a widely accepted sleep hygiene practice, yet few studies have assessed meal timing as a risk factor for disrupted sleep. This study examined the relationship between evening meal timing and sleep quality in young adults. A total of N = 793 participants (26% male) aged between 18 and 29 years responded to an online survey, which captured sociodemographic information, lifestyle variables, and sleep characteristics. Meal timing was defined as meals more than 3 h before or within 3 h of bedtime. The outcomes were as follows: one or more nocturnal awakenings, sleep onset latency of >30 min, and sleep duration of ≤6 h. Logistic regression analyses showed that eating within 3 h of bedtime was positively associated with nocturnal awakening (OR = 1.61, 95% CI = 1.15–2.27) but not long sleep onset latency (1.24; 0.89–1.73) or short sleep duration (0.79; 0.49–1.26). The relationship remained significant after adjusting for potential confounders of ethnicity and body mass index (OR = 1.43, 95% CI = 1.00–2.04). Meal timing appears to be a modifiable risk factor for nocturnal awakenings and disrupted sleep. However, this is a preliminary cross-sectional study and highlights the need for additional research on the influence of the timing of food intake on sleep.

Biological changes in adolescents exert a very dominant influence on hormonal mechanisms. One of them is the occurrence of leukorrhea as a result of biological changes in adolescents. But this leukore also can not be ignored, because leukore can be a sign of certain diseases. The purpose of this study was to identify the incidence of leukorrhea in adolescents, anxiety in adolescents, and patterns of adolescent activity, and the relationship between patterns of activity and anxiety with leukorrhea in adolescents. Research design using observational analytic research with cross sectional approach. The population was students of Aisyiyah University in Yogyakarta. Samples of 71 girls were taken by random sampling technique. Data collection techniques used to collect primary data using a structured questionnaire. The data obtained were then analyzed using the univariate formula (frequency distribution formula) and bivariate (Chi square formula). The results of Leukore occurrences in adolescent girls by 79% and those without vaginal discharge by 21%. 49 adolescents experienced a 67% abnormal activity pattern and the remaining 24 adolescents experienced a 33% normal activity pattern. 26% of students experienced anxiety and moderate anxiety 36%, mild anxiety 11% and those without anxiety as much as 17%. The results of the analysis stated that the most respondents with abnormal activity patterns and experienced vaginal discharge as much as 48%. From the results of the analysis with the chi-square test, the level of closeness of the relationship between the two variables showed a significant value of 0.014 (p <0.05). There is a correlation between activity patterns with the incidence of vaginal discharge in adolescents and most respondents with severe anxiety and experiencing vaginal discharge as much as 34%. From the results of the analysis with the chi-square test, the level of closeness of the relationship between the two variables showed a significant value of 0.01 (p <0.05). There is a relationship between anxiety level and the incidence of vaginal discharge in young women.

Purpose. To examine the relationship between readiness to change exercise behavior and smoking behavior, stratified by gender. Methods. A cross-sectional survey of those inhabitants of Hikami, Japan, who were 30 years of age or older (n = 11,708). The response rate was 82.1%. Chi-squared tests and analysis of variance were used to evaluate differences in characteristics by smoking behavior, and the odds ratio (OR) was calculated to examine the relationship while controlling for possible confounding factors such as age, body mass index, and health consciousness. Results. Even when controlling for confounding factors, the relationship between the two behaviors differed according to gender. Among males, ex-smokers were more likely to be motivated to exercise (OR, 1.14; 95% confidence interval [CI], .95–1.36), whereas among females, smokers were more likely to be motivated to exercise (OR, .40; 95% CI, .34–.48). Discussion. Despite some limitations, the findings suggest that gender should be used as a stratification variable when discussing the relationship between smoking and exercise behaviors.
