Preschool children’s temperament and its associations with energy intake

Abstract Background and objectives Child's temperament dimensions have been linked with different weight outcomes as well as dietary factors such as consumption of fruit and vegetables, sugar-rich foods and drinks and an overall dietary quality. Links between temperament dimensions and energy intake, however, remain under-examined. This study expands the literature by investigating associations between child's temperament dimensions and energy intake. Methods Altogether 505 Finnish children aged 3-6 years provided data for the analyses. The data is a part of the DAGIS (Increased Health and Wellbeing in Preschools) study conducted in 2015-2016. Child's energy intake was measured with 3-day food records. To be included, children had to 1) have food record for two preschool days and one weekend day and 2) to have consumed both lunch and an afternoon snack in the preschool on the two preschool days. The very short form of Children's Behavior Questionnaire was used to measure child's temperament dimensions. Concurrent associations between three temperament dimensions (surgency, negative affectivity, and effortful control) and energy intake were examined using linear regression models adjusted for child's age, sex, mother's highest education, and moderate-to-vigorous physical activity. Results Surgency, temperament dimension referring to characteristics such as impulsivity, high activity level and high approach, was positively associated with energy intake. Effortful control or negative affectivity were not associated with energy intake. Conclusions The findings imply that temperamental surgency may be one relevant determinant of energy intake among preschool children. The result is in line with previous studies linking child's surgency as well as its specific facets, such as impulsivity, with weight outcomes and food approach behaviors. Considering child's individual temperament dimensions when counselling families in eating issues could be beneficial. Key messages • Surgency, a temperament dimension referring to characteristics such as impulsivity, high activity level and high approach, was positively associated with energy intake. • When promoting children’s balanced eating, tailored support for parents acknowledging child’s temperament could be beneficial.

Adherence to Caloric and Protein Recommendations in Older Hemodialysis Patients: A Multicenter Study.

Hemodialysis (HD) patients are characterized by malnutrition, which adversely affects their survival. The development of malnutrition is influenced, among other factors, by improper diet and the advanced age of patients. The study aimed to assess the nutritional status and adherence to dietary recommendations among older patients. The multicenter study included 179 stable HD patients. The nutritional status was assessed by a 7-point Subjective Global Assessment (SGA). Anthropometry and body composition was analyzed. The diet was assessed based on the 3-day food diary and the Food Frequency Questionnaire with 6 answers (FFQ-6). Blood laboratory tests were performed. Based on the 7-point SGA, malnutrition was diagnosed in 38.5% of HD patients. The decreased content of the muscle tissue (LTI < 14 kg/m2) was observed in 70.4% of the examined patients and the decreased concentration of s-albumin was observed in 44.1% of patients. Older patients had significantly lower LTI. 26% of patients consumed less than 25 kcal/kg body weight and less than 0.8 g protein/kg body weight. Older patients’ diets contained significantly fewer calories. There were significant differences between nutrient intake on a weekday with dialysis, a weekday without dialysis, and a weekend day without dialysis. The lowest intake of nutrients was observed on the day of dialysis. Nutritional education and the determination of whether food is permitted during hemodialysis are necessary to improve patients’ nutrition.

Effect of Text Messaging Parents of School-Aged Children on Outdoor Time to Control Myopia

Myopia in school-aged children is a public health issue worldwide; consequently, effective interventions to prevent onset and progression are required. To investigate whether SMS text messages to parents increase light exposure and time outdoors in school-aged children and provide effective myopia control. This randomized clinical trial was conducted in China from May 2017 to May 2018, with participants observed for 3 years. Of 528 965 primary school-aged children from Anyang, 3113 were randomly selected. Of these, 268 grade 2 schoolchildren were selected and randomly assigned to SMS and control groups. Data were analyzed from June to December 2021. Parents of children in the SMS group were sent text messages twice daily for 1 year to take their children outdoors. All children wore portable light meters to record light exposure on 3 randomly selected days (2 weekdays and 1 weekend day) before and after the intervention. The co-primary outcomes were change in axial length (axial elongation) and change in spherical equivalent refraction (myopic shift) from baseline as measured at the end of the intervention and 3 years later. A secondary outcome was myopia prevalence. Of 268 grade 2 schoolchildren, 121 (45.1%) were girls, and the mean (SD) age was 8.4 (0.3) years. Compared with the control group, the SMS intervention group demonstrated greater light exposure and higher time outdoors during weekends, and the intervention had significant effect on axial elongation (coefficient, 0.09; 95% CI, 0.02-0.17; P = .01). Axial elongation was lower in the SMS group than in the control group during the intervention (0.27 mm [95% CI, 0.24-0.30] vs 0.31 mm [95% CI, 0.29-0.34]; P = .03) and at year 2 (0.39 mm [95% CI, 0.35-0.42] vs 0.46 mm [95% CI, 0.42-0.50]; P = .009) and year 3 (0.30 mm [95% CI, 0.27-0.33] vs 0.35 mm [95% CI, 0.33-0.37]; P = .005) after the intervention. Myopic shift was lower in the SMS group than in the control group at year 2 (-0.69 diopters [D] [95% CI, -0.78 to -0.60] vs -0.82 D [95% CI, -0.91 to -0.73]; P = .04) and year 3 (-0.47 D [95% CI, -0.54 to -0.39] vs -0.60 D [95% CI, -0.67 to -0.53]; P = .01) after the intervention, as was myopia prevalence (year 2: 38.3% [51 of 133] vs 51.1% [68 of 133]; year 3: 46.6% [62 of 133] vs 65.4% [87 of 133]). In this randomized clinical trial, SMS text messages to parents resulted in lower axial elongation and myopia progression in schoolchildren over 3 years, possibly through increased outdoor time and light exposure, showing promise for reducing myopia prevalence.

Feasibility and Impact of Physical Activity on Compassion Fatigue and Burnout Among Ambulatory Care Oncology Nurses.

Compassion fatigue (CF) and burnout are well described phenomena among oncology nurses. Physical activity (PA) has been shown to reduce CF and burnout. The purpose of this pilot study was to determine the feasibility of promoting PA and assessing its impact on CF and burnout among RNs across three ambulatory care cancer clinics. A convenience sample of nurses with varying roles were invited to participate. Feasibility was assessed by participant accrual and retention rates. CF and burnout were assessed at weeks 0, 6, and 12. The Yale Physical Activity Survey was used to obtain self-reported PA, and daily steps were tracked using participants' personal devices. Stress scores decreased. Burnout scores demonstrated levels of low emotional exhaustion, moderate depersonalization, and moderate to high personal achievement. Leisurely walking increased significantly, and average daily step counts increased by 37% for weekdays, 10% for weekend days, and 29% for the total week.

Development and validation of a smartphone image-based app for dietary intake assessment among Palestinian undergraduates

Accurate dietary assessment is required in a variety of research fields and clinical settings. Image-based dietary assessment using smartphones applications offer the opportunity to reduce both researcher and participant burden compared to traditional dietary assessment methods. The current study, conducted in Palestine, aimed to design an image-based dietary assessment application, to assess the relative validity of the application as a dietary assessment tool for energy and macronutrient intake using the 3-Day Food Record (3-DFR) as a reference method, and to test its usability among a sample of Palestinian university students. The development of a smartphone application (Ghithaona) designed to assess energy and macronutrient intake is reported. The application validity was tested among a sample of Palestinian undergraduates from An-Najah National University. Participants recorded their dietary intake using the Ghithaona application over 2 consecutive days and 1 weekend day. Intake from the Ghithaona application were compared to intake collected from 3-DFR, taken on 2 consecutive weekdays and 1 weekend day, in the second week following the Ghithaona application. At the end of the study, participants completed an exit survey to test assess application usability and to identify barriers to its use. Mean differences in energy, and macronutrients intake were evaluated between the methods using paired t-tests or Wilcoxon signed-rank tests. Agreement between methods was ascertained using Pearson correlations and Bland–Altman plots. The Ghithaona application took 6 months to develop. The validation test was completed by 70 participants with a mean age of 21.0 ± 2.1 years. No significant differences were found between the two methods for mean intakes of energy or macronutrients (p > 0.05). Significant correlations between the two methods were observed for energy, and all macronutrients (r = 0.261–0.58, p ≤ 0.05). Bland–Altman plots confirmed wide limits of agreement between the methods with no systematic bias. According to the exit survey, it was found that majority of participants strongly agreed and agreed that the application saves time (94.2%), helps the participant to pay attention to their dietary habits (87.2%), and is easy to use (78.6%). The Ghithaona application showed relative validity for assessment of nutrient intake of Palestinian undergraduates.

Testing Day-Of-The-Week Persistence and Seasonality in Spanish Electricity Energy Prices

Day-of-the-week persistence and seasonality of electricity prices in Spain, spanning 01/01/2006 to 04/11/2021, are investigated by employing updated fractional persistence frameworks in non-linear settings. The results show marginal higher persistence in electricity prices during the working days (Tuesday, Wednesday, Thursday, and Friday) compared to weekend days. In all cases, electricity prices are mean-reverting with long-range dependence properties. Results also show that the monthly electricity price series contain no seasonal effect.

Physical activity and its correlates in people with cystic fibrosis: a systematic review.

Cystic fibrosis (CF) is a life-shortening genetic disease, affecting multiple life domains including physical activity (PA). Although higher PA levels are associated with multiple health benefits, little insight exists on the PA level of people with CF (PwCF) compared to healthy peers. Evidence on the influencing factors (i.e. correlates) of PA in this clinical population is scarce, but essential to fully understand their PA behaviour. Therefore, the present review aims to provide an overview of the PA level of PwCF compared to healthy peers, and the correlates of PA in PwCF. A systematic search of three databases resulted in 46 included studies. Analysis of 16 studies showed that the CF population is equally active compared to healthy peers, but there is a trend towards less high-intensity PA in youths with CF. Furthermore, PA is positively associated with quality of life, lung function, (maximal) exercise capacity, bone mineral density and quadriceps force. Also, PA was lower on weekdays compared to weekend days and lower when experiencing pulmonary exacerbations. More high-quality research is required in PwCF, particularly longitudinal studies that further explore the correlates of PA, with PA investigated as a primary outcome and measured objectively.

A Study On The Daytime Variation Degree Of Adolescents' Physical Activity Level

PURPOSE: Provide references for further exploring the possible factors that affect the daily variation characteristics of adolescents' physical activity and appropriate intervention strategies by analyzing the degree of day-time variation of vigorous physical activity (MVPA) and sitting time among adolescents. METHODS: The subjects of the study were 148 middle school and high school students in Beijing. They wore ActigraphGT3X three-axis accelerometers for one week to record the daily MVPA and sitting time. The height and weight of the subjects were also measured. RESULTS: The MVPA on school days was higher than that on weekends (49.39 min/d vs 34.24 min/d, P < 0.05). The MVPA of boys on school days and weekends was higher than that of girls (P < 0.05); The sitting time on school days and weekends was 566.48 min/d and 588.55 min/d, respectively, with no statistical difference (P > 0.05); boys’ sitting time on school days and weekends was lower than that of girls (P < 0.05); the coefficient of variation of MVPA for adolescents on school days (0.385 ± 0.168) was lower than that of weekend days (0.593 ± 0.455), and the difference was statistically significant (P < 0.01). The coefficient of variation of sitting time was not statistically different (P > 0.05) between school days (0.167 ± 0.077) and weekend days (0.145 ± 0.126). The coefficient of variation of MVPA in adolescents within one week was higher than that of sitting in one week (0.517 ± 0.177 vs 0.175 ± 0.065, P < 0.01). CONCLUSIONS: Adolescents have higher levels of physical activity on school days, and more significant insufficiency of physical activity on weekends; MVPA time variation is higher within a week, especially on weekends; sitting time is steadily at a higher level; boys are more active than girls and have a higher degree of physical activity variation. In the context of the national "double reduction" policy, in addition to the active measures taken by schools to increase the physical activity of adolescents, strengthening interventions for girls and weekends are particularly important to increase the level of physical activity for adolescents. This Study was Supported by the Planning subject for the 13th five year plan of Beijing education sciences (BEAA19045)

Participants With ACL Injury Have Poor Diet Quality And Lower Energy Intake After Reconstruction Surgery.

PURPOSE: High-quality diet and sufficient energy support optimal recovery following orthopedic injury. Our goal is to determine participants’ energy intake and diet quality before and after anterior cruciate ligament (ACL) reconstruction. METHODS: Thirty-six participants (mean ± SD; age, 21.5 ± 5.9; BMI, 25.1 ± 4.0; 53% female) who sustained an ACL tear volunteered for a physical therapy rehabilitation study. Concurrent with the parent trial, 3-day diet records were collected before and after ACL reconstruction. Participants recorded food and drink intake for two weekdays and one weekend day. A registered dietitian educated participants about keeping food records and estimating portion sizes. The dietitian prompted participants to complete records on assigned days and checked diet logs throughout the recording period for completeness. Energy consumption was analyzed through Nutrition Data System for Research (NDSR), and diet quality was measured using Healthy Eating Index 2015 (HEI-2015). Paired t-tests were used to compare pre-and post-surgery average energy intake (kcal), weight (kg), and protein (g/kg). One-sample tests were used to compare HEI-2015 to population averages for children and adults using NHANES 2015-2016 data. RESULTS: Average energy consumption decreased from pre-surgery to post-surgery (1797.3 ± 588.9 vs. 1587.8 ± 604.9, respectively; p = 0.029). Comparisons pre- and post-surgery for weight (74.9 kg ±18.0 vs. 74.5 ± 18.5), kcal/kg (24.8 ± 7.5 vs 22.3 ± 8.8), and protein g/kg (0.99 ± 0.35 vs. 0.97 ± 0.44) did not show differences. HEI-2015 was significantly lower in teenagers pre- and post-surgery compared to the US average of 53 for Americans age 2-19 (42.4 ± 8.5; p < .001; 42.7 ± 9.8; p < .001). Adult participants’ HEI was significantly lower than the US average of 59 only after ACL reconstruction (53.2 ± 13.3; p = 0.073; 50.5 ± 13.2; p = 0.011). Children had significantly lower HEI-2015 than adults before reconstruction (42.4 ± 8.5 vs 53.2 ± 13.3; p = 0.007) but not after (42.7 ± 9.8 vs 50.5 ± 13.2; p = 0.057). CONCLUSION: On average, energy intake decreases following ACL surgery in young participants. Future research should address links between diet quality, reduced energy intake and recovery following ACL surgery.

P09-04 Sedentary time measured by GT3X+ accelerometry and its variation with grade level and gender among children and adolescents in Morocco

BackgroundSedentary behavior (SB) in children is related to different health outcomes such as overweight and cardio-metabolic diseases. These negative effects have been widely supported by evidence. However, no data on sedentary time (ST) among Moroccan children has been available, yet. Therefore, the present study examined gender and grade differences in objectively measured sedentary behavior in a sample of Moroccan primary school children and adolescents.MethodsIn total, 172 Moroccan children/adolescents aged between 8 to 14 years old (mean age = 10.92 ± 1.55 years; 49.4% were boys) completed the survey. School grade, gender, height, and weight were collected by questionnaires and ST objectively measured using a tri-axial accelerometer (GTX3+). Study required at least 3 valid weekdays and 1 weekend day with? 600 min/day total wear time. Two-way analysis of covariance and logistic regression analyses, adjusted for BMI z-score and accelerometer wear time, were used to examine gender and grade differences in ST.ResultsMean time spent in SB was 535.93 ± 87.15 min/day or ∼ 62.94% of the average daily accelerometer wear time of 851.45 ±51.35.min/day with statistical differences between weekend and week days (471.357 ± 127.73 minutes/day vs. 559.7661± 90.75 minutes/day; p > 0.001). Adolescents (11-14y) were more involved in sitting tasks when compared to the early grades (8-10y). 550.011±88.827 vs. 521.845±83.602 respectively; p > 0.001.ConclusionST increases between ages 11 and 14 years. On week days children and adolescents spent sitting longer than at weekends. Girls and adolescents were identified as potential risk groups. This report on ST presents valuable information for designing and implementing interventions to decrease time spent in SB among children during class time.

O1-3 Time spent cycling, running, walking, standing, sitting, and lying: a cross-sectional analysis of accelerometer-data from 930 Danes aged 15-94 in the Moving Denmark study

BackgroundPhysical activity is essential for public health. Newer device-based measures can identify different activity behaviors, which is useful to focus future health promotion initiatives. The objectives of this study were to describe time spend cycling, running, walking, standing, sitting, and lying during a regular day using accelerometers, and to describe differences between age-groups and gender.MethodsIn the Moving Denmark study a representative sample of 400.000 Danes were invited to a national survey. A subsample of 1525 respondents gave consent to wear an accelerometer (Axivity AX3 attached to the right thigh; 24 h/day, 7 consecutive days) of which 930 fulfilled the inclusion criteria (min. 3 valid weekdays and 1 valid weekend day with data). Daily time spent biking, running, walking, standing, sitting, and lying were derived using the method proposed by Skotte et al. (2014) using 1-s epochs, and differences between age-groups (15-25, 26-45, 46-65, +66 y/o) and gender were investigated using Kruskal-Wallis rank sum test.ResultsAmong those cycling (39.2%) and those running (67.9%), the mean time per day was 8.4 minutes for cycling and 2.8 minutes for running. The mean time walking, standing, sitting, and lying was 93.5, 183.2, 572.1, and 542.2 min/day, respectively. No significant difference was observed between age groups on biking, but time spend biking was highest among men. Average time spend running and walking was highest among the youngest participants (15-25 y/o), but with no differences observed on gender. No difference between age groups were found for standing, but the average time spend standing was significantly higher for women compared to men. Average sitting time was significantly higher among the older participants (+66 y/o), whereas time spend lying was highest among the youngest participants, but with no differences observed on gender.ConclusionsThe study show that at least 67.9% of the sample are active through either biking, running, or both, but also that the average daily minutes are limited. Men accumulate in average more minutes of biking, and women more minutes of standing. The younger participants had more minutes of walking, running, and lying, while the older participants more often were sitting.

P03-04 Perceived and objective indicators of neighbourhood safety and physical activity in early adolescence: a national cohort study

BackgroundThe health benefits of regular physical activity in adolescence are well-documented. Currently, young people in the UK are not achieving recommended levels of physical activity. The neighbourhood environment is a key setting for physical activity in adolescence. Due to lack of financial independence and mobility restrictions, adolescents spend a significant amount of time in their neighbourhood. Feeling unsafe in their neighbourhood may be a potential barrier to physical activity.This study aims to examine associations between objective and subjective measures of neighbourhood safety and physical activity.MethodsParticipants (n = 11,726) came from the Millennium Cohort Study; a nationally representative UK longitudinal birth cohort. At age 11 perceived neighbourhood safety was assessed via questionnaire and the Index of Multiple Deprivation (IMD) crime domain was linked to participant postcode data. At age 14, participants self-reported physical activity and a subsample (n = 4,813) also wore GENEActiv wrist-worn activity monitors for one weekday and one weekend day. Associations between perceived safety, IMD crime and self-reported physical activity were quantified using linear regression models. Zero Inflated Poisson (ZIP) models were used to examine associations with accelerometer-measured physical activity. We adjusted for parental education, family income, ethnicity and season of accelerometer wear. An interaction term for sex was tested to assess whether associations between perceived safety and physical activity differed by sex. Models were also stratified by sex.ResultsFeeling not safe compared to very safe was associated with 0.28 (95% CI -0.50, -0.06) fewer days of self-reported physical activity. However, no association was seen between perceived safety and accelerometer physical activity. Those living in the highest IMD crime areas reported on average 0.31 (95% CI -0.47, -0.15) fewer days of physical activity compared to those living in the lowest crime areas. Individuals living in the highest IMD crime areas achieved 5.56 fewer minutes of daily accelerometer-measured exercise than those in least crime areas.ConclusionsThis study demonstrates consistent associations between perceived safety and objective crime with physical activity levels in adolescence.

Wearables for Measuring the Physical Activity and Sedentary Behavior of Patients With Axial Spondyloarthritis: Systematic Review.

BackgroundAxial spondyloarthritis (axSpA) is an inflammatory rheumatic disease associated with chronic back pain and restricted mobility and physical function. Increasing physical activity is a viable strategy for improving the health and quality of life of patients with axSpA. Thus, quantifying physical activity and sedentary behavior in this population is relevant to clinical outcomes and disease management. However, to the best of our knowledge, no systematic review to date has identified and synthesized the available evidence on the use of wearable devices to objectively measure the physical activity or sedentary behavior of patients with axSpA.ObjectiveThis study aimed to review the literature on the use of wearable activity trackers as outcome measures for physical activity and sedentary behavior in patients with axSpA.MethodsPubMed, PEDro, and Cochrane electronic databases were searched in July 2021 for relevant original articles, with no limits on publication dates. Studies were included if they were original articles, targeted adults with a diagnosis of axSpA, and reported wearable device–measured physical activity or sedentary behavior among patients with axSpA. Data regarding the study’s characteristics, the sample description, the methods used for measuring physical activity and sedentary behavior (eg, wearable devices, assessment methods, and outcomes), and the main results of the physical activity and sedentary behavior assessments were extracted.ResultsA total of 31 studies were initially identified; 13 (13/31, 42%) met the inclusion criteria, including 819 patients with axSpA. All the studies used accelerometer-based wearable devices to assess physical activity. Of the 13 studies, 4 (4/31, 31%) studies also reported outcomes related to sedentary behavior. Wearable devices were secured on the wrists (3/13 studies, 23%), lower back (3/13, 23%), right hip (3/13, 23%), waist (2/13, 15%), anterior thigh (1/13, 8%), or right arm (1/13, 8%). The methods for reporting physical activity and sedentary behavior were heterogeneous. Approximately 77% (10/13) of studies had a monitoring period of 1 week, including weekend days.ConclusionsTo date, few studies have used wearable devices to quantify the physical activity and sedentary behavior of patients with axSpA. The methodologies and results were heterogeneous, and none of these studies assessed the psychometric properties of these wearables in this specific population. Further investigation in this direction is needed before using wearable device–measured physical activity and sedentary behavior as outcome measures in intervention studies in patients with axSpA.Trial RegistrationPROSPERO CRD42020182398; https://tinyurl.com/ec22jzktInternational Registered Report Identifier (IRRID)RR2-10.2196/23359

Does physical activity timing differentially correlate with symptoms of restless legs syndrome in adults with multiple sclerosis?

Objective/backgroundThe present study examined the associations among physical activity during different times of the day(i.e., morning, midday,evening) and days of the week(i.e., weekdays, weekend days) with restless legs syndrome(RLS) severity and sleep quality in adults with multiple sclerosis(MS). Patients/methodsParticipants(N = 39) completed the International Restless Legs Syndrome Study Group Scale and the Pittsburgh Sleep Quality Index as measures of RLS severity and global sleep quality, respectively, and wore an ActiGraph GT3X + on the non-dominant hip for seven days for measuring physical activity(i.e., light physical activity[LPA], moderate-to-vigorous physical activity[MVPA], and steps). ResultsThere was a significant effect of time of day wherein participants had more midday activity compared with morning or evening for LPA, MVPA, and steps; there was no effect of day of the week. Spearman's rho correlations across the week indicated higher evening LPA, evening steps, and overall daily steps (ρ = −0.42,ρ = −0.51,ρ = −0.40,respectively) were associated with lower RLS severity. Similar associations were demonstrated for weekdays(ρ = −0.39,ρ = −0.50,ρ = −0.41,respectively) and weekend days(ρ = −0.44,ρ = −0.51,ρ = −0.39,respectively). Higher evening MVPA on weekend days(ρ = −0.42) was associated with lower RLS severity. Higher morning and overall daily LPA(ρ = 0.34,ρ = 0.33,respecitvely) were associated with worse sleep quality. Similar associations were demonstrated on weekdays(ρ = 0.33,ρ = 0.37,respectively) and more evening MVPA(ρ = 0.32) was associated with worse sleep quality. On weekend days, more morning MVPA(ρ = 0.42) was associated with worse sleep quality. ConclusionsOur results suggest that undertaking physical activity, particularly LPA and steps, in evenings may be important for managing symptoms of RLS without worsening sleep quality.

Patterns of Alcohol Consumption Among Individuals With Alcohol Use Disorder During the COVID-19 Pandemic and Lockdowns in Germany

Alcohol consumption (AC) leads to death and disability worldwide. Ongoing discussions on potential negative effects of the COVID-19 pandemic on AC need to be informed by real-world evidence. To examine whether lockdown measures are associated with AC and consumption-related temporal and psychological within-person mechanisms. This quantitative, intensive, longitudinal cohort study recruited 1743 participants from 3 sites from February 20, 2020, to February 28, 2021. Data were provided before and within the second lockdown of the COVID-19 pandemic in Germany: before lockdown (October 2 to November 1, 2020); light lockdown (November 2 to December 15, 2020); and hard lockdown (December 16, 2020, to February 28, 2021). Daily ratings of AC (main outcome) captured during 3 lockdown phases (main variable) and temporal (weekends and holidays) and psychological (social isolation and drinking intention) correlates. Of the 1743 screened participants, 189 (119 [63.0%] male; median [IQR] age, 37 [27.5-52.0] years) with at least 2 alcohol use disorder (AUD) criteria according to the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) yet without the need for medically supervised alcohol withdrawal were included. These individuals provided 14 694 smartphone ratings from October 2020 through February 2021. Multilevel modeling revealed significantly higher AC (grams of alcohol per day) on weekend days vs weekdays (β = 11.39; 95% CI, 10.00-12.77; P < .001). Alcohol consumption was above the overall average on Christmas (β = 26.82; 95% CI, 21.87-31.77; P < .001) and New Year's Eve (β = 66.88; 95% CI, 59.22-74.54; P < .001). During the hard lockdown, perceived social isolation was significantly higher (β = 0.12; 95% CI, 0.06-0.15; P < .001), but AC was significantly lower (β = -5.45; 95% CI, -8.00 to -2.90; P = .001). Independent of lockdown, intention to drink less alcohol was associated with lower AC (β = -11.10; 95% CI, -13.63 to -8.58; P < .001). Notably, differences in AC between weekend and weekdays decreased both during the hard lockdown (β = -6.14; 95% CI, -9.96 to -2.31; P = .002) and in participants with severe AUD (β = -6.26; 95% CI, -10.18 to -2.34; P = .002). This 5-month cohort study found no immediate negative associations of lockdown measures with overall AC. Rather, weekend-weekday and holiday AC patterns exceeded lockdown effects. Differences in AC between weekend days and weekdays evinced that weekend drinking cycles decreased as a function of AUD severity and lockdown measures, indicating a potential mechanism of losing and regaining control. This finding suggests that temporal patterns and drinking intention constitute promising targets for prevention and intervention, even in high-risk individuals.

COVID-19 impacts on residential occupancy schedules and activities in U.S. Homes in 2020 using ATUS

Many aspects of the daily lives of those living in the United States were substantially impacted by the COVID-19 pandemic in the year 2020. A broad diversity of measures was implemented to curb the spread of the virus, many of which included adjustments to where and how people worked, went to school, and otherwise conducted their daily lives compared to pre-pandemic times. This has impacted how residential buildings are used, how much time people spend in their homes, and as a result, how much energy these buildings consume. The main objective of this study is to analyze, at a national scale, the differences in the occupancy schedules and activities conducted in homes in the U.S., as compared to pre-pandemic. 15 years of American Time Use Survey and Current Population Survey data, from 2006 to 2020, was used in this study to analyze the occupancy schedules for both pandemic (2020) and pre-pandemic (2006–2019) times. These impacts were also analyzed with respect to variables including, weekday/weekend, month of the year, age of the occupants, household income, and household size. The impact of the pandemic on occupant schedules were most substantial in the initial months, whereas as the months progressed, these occupancy profiles slowly changed. Across 2020, people spent, on average, 8 % more time (1.9 h) in their home on weekdays, and 3–6 % (1.2 h) on weekend days. The percentage of time spent for different activities and locations within homes were also studied. For 1-member households, their time spent at home decreased whereas for 2-, 3-, and 4- member households, they spent more time at home. Overall, people spent around 45% more time doing office- and work-related activities at home compared to pre-pandemic, which is likely due to increased remote working and schooling. This research helps to improve the understanding of the occupancy presence and absence profiles in U.S. residential buildings due to the pandemic and provides new insights as to modified profiles for researchers, building designers, and policy makers.

Dietary Patterns in Association With Hypertension: A Community-Based Study in Eastern China.

ObjectiveThis study aimed to explore the association between dietary patterns and hypertension based on a community–based survey in Suzhou, Eastern China.MethodsThis cross–sectional analysis was undertaken from the subset of the Suzhou Food Consumption and Health State Survey in 2018–2019. Adults aged ≥ 18 years were invited to participate in this survey. Dietary intake was collected by a 24–h dietary recall and a weighing method over three consecutive days (including two weekdays and one weekend day). Dietary patterns were defined using factor analysis. Association between the dietary patterns and hypertension was examined by multivariable logistic regression models with adjustment for covariates. Moreover, sensitivity analysis was used to reinforce our findings.ResultsA total of 2,718 participants were included in the final analysis. Rice-vegetable pattern, fast food pattern, fruit-dairy pattern, and wheat-meat pattern were identified. We observed that the fruit-dairy pattern was inversely associated with hypertension after adjustment for all the covariates (OR = 0.55; 95% CI: 0.40, 0.75; P = 0.002). The association between the wheat-meat pattern and hypertension was attenuated and became statistically nonsignificant in sensitivity analyses. The other two patterns were not significantly associated with hypertension (P > 0.05).ConclusionThe fruit-dairy pattern was inversely associated with the risk of hypertension among Chinese adults. Our findings further emphasize the important role of optimal diet combination in the prevention of hypertension.

Differences in physical activity between weekdays and weekend days among U.S. children and adults: Cross-sectional analysis of NHANES 2011–2014 data

This study investigates differences in physical activity between weekdays and weekend days, and its associations with sociodemographic and anthropometric characteristics in the U.S population using the NHANES 2011–2014 data. Physical activity was measured using ActiGraph GT3X+. Raw acceleration data were converted to Monitor-Independent Movement Summary units (MIMS-units) that account for inter-device variability and eliminates non-human movement. The daily MIMS-units were averaged for weekdays and weekend days. Demographic characteristics were self-reported. Height and weight were objectively measured. The sample included 6611 adults aged ≥ 20 years and 3520 children aged between 6 and 19 years. The results show that more MIMS-units were registered on weekdays compared to weekend days for adults (652, 95%CI = 533, 770) and children (889, 95%CI = 702, 1076). Factors associated with physical activity in adults (gender, age, marital status, ethnicity, education level, and weight status) were similar for weekdays and weekend days. In children, physical activity was associated with ethnicity, weight status, and age. The level of differences in physical activity between weekdays and weekend days among adults was larger for men, Hispanic Americans, and those with lower education levels. Differences among children were similar across subgroups, except for those aged 16–19 years who had smaller level of difference compared to those aged 12–15 years. In conclusion, adults and children were more active on weekdays than weekend days. The effects of structured days (i.e., weekdays) on physical activity appeared to be similar across most child subgroups but more heterogeneous for adult subgroups. Interventions increasing physical activity opportunities during weekend days are warranted.
