Patient and Operational Factors Do Not Substantively Affect the Annual Departmental Quality of Anesthesiologists' Clinical Supervision and Nurse Anesthetists' Work Habits.

INTRODUCTION: Although safety climate, teamwork, and other non-technical skills in operating rooms probably influence clinical outcomes, direct associations have not been shown, at least partially due to sample size considerations. We report data from a retrospective cohort of anesthesia evaluations that can simplify the design of prospective observational studies in this area. Associations between non-technical skills in anesthesia, specifically anesthesiologists' quality of clinical supervision and nurse anesthetists' work habits, and patient and operational factors were examined. METHODS: Eight fiscal years of evaluations and surgical cases from one hospital were included. Clinical supervision by anesthesiologists was evaluated daily using a nine-item scale. Work habits of nurse anesthetists were evaluated daily using a six-item scale. The dependent variables for both groups of staff were binary, whether all items were given the maximum score or not. Associations were tested with patient and operational variables for the entire day. RESULTS: There were 40,718 evaluations of faculty anesthesiologists by trainees, 53,772 evaluations of nurse anesthetists by anesthesiologists, and 296,449 cases that raters and ratees started together. Cohen's d values were small (≤0.10) for all independent variables, suggesting a lack of any clinically meaningful association between patient and operational factors and evaluations given the maximum scores. For supervision quality, the day's count of orthopedic cases was a significant predictor of scores (P = 0.0011). However, the resulting absolute marginal change in the percentage of supervision scores equal to the maximum was only 0.8% (99% confidence interval: 0.2% to 1.4%), i.e., too small to be of clinical or managerial importance. Neurosurgical cases may have been a significant predictor of work habits (P = 0.0054). However, the resulting marginal change in the percentage of work habits scores equal to the maximum, an increase of 0.8% (99% confidence interval: 0.1% to 1.6%), which was again too small to be important. CONCLUSIONS: When evaluating the effect of assigning anesthesiologists and nurse anesthetists with different clinical performance quality on clinical outcomes, supervision quality and work habits scores may be included as independent variables without concern that their effects are confounded by association with the patient or case characteristics. Clinical supervision and work habits are measures of non-technical skills. Hence, these findings suggest that non-technical performance can be judged by observing the typical small sample size of cases. Then, associations can be tested with administrative data for a far greater number of patients because there is unlikely to be a confounding association between patient and case characteristics and the clinicians' non-technical performance.

Unhealthy diets increase the likelihood of being overweight or obese among African migrant students in China, but not among African non-migrant students: a cross-sectional study.

Background: The impact of non-communicable diseases (NCDs) is disproportionately felt by immigrants from low- to medium-income countries (LMICs), partly due to their dietary habits. To thrive in their new environment, migrants either omit or consume certain food items, which could lead to nutritional deficits. As a result, most migrants experience more NCDs than their compatriots in their native countries. Therefore, we evaluated the difference in dietary habits, quality, and the influencing factors of overweight or obesity among African migrant students in Nanjing (China) and non-migrant students in Africa using cross-sectional data. Methods: The researchers used the food frequency questionnaire and the global diet quality score metrics to assess food intake and quality, respectively. Then, cross-tabulation was employed to explore the differences between the groups in meal skipping, eating habits, and diet quality. Finally, the factors associated with overweight or obesity were assessed with binary logistic regression stratified by African students in Nanjing and students in their native countries. Results: Approximately 678 responses were received, mainly between 18-25 years (46.7%) and 26-36 years (45.4 %). The majority of them (52.3%) were international students. The non-migrant African students' diets lacked citrus fruits (22.2%), deep orange fruits (15.4%), deep orange vegetables (18%), cruciferous vegetables (24.6%), and dark leafy vegetables (26.5%). While the African migrant students consumed more high-fat dairy (50.7%), processed meats (23.9%), sweets and ice creams (51.3%), sugar-sweetened beverages (40.5%), and juice (61.5%), p < 0.001. Furthermore, consuming late-night meals constantly [Exp (B) = 39.607, p = 0.049], eating twice a day [Exp (B) = 6.527, p = 0.036], consuming red meat [Exp (B) = 29.287, p = 0.001], processed meats [Exp (B) = 719.979, p = 0.0011], refined grains and baked foods [Exp (B) = 15.752, p = 0.013], and sweets and ice cream [Exp (B) = 193.633, p = 0.006] were factors inducing overweight or obesity among only African migrant students. Conclusion: Controlling the what (Western diet and nature of late-night meals) and the when of eating can drastically reduce their influence on obesogenic condition formation in African migrant students in China and elsewhere.

Human gut microbiome, diet, and mental disorders.

Diet is one of the most important external factor shaping the composition and metabolic activities of the gut microbiome. The gut microbiome plays a crucial role in host health, including immune system development, nutrients metabolism, and the synthesis of bioactive molecules. In addition, the gut microbiome has been described as critical for the development of several mental disorders. Nutritional psychiatry is an emerging field of research that may provide a link between diet, microbial function, and brain health. In this study, we have reviewed the influence of different diet types, such as Western, Mediterranean, vegetarian, and ketogenic, on the gut microbiota composition and function, and their implication in various neuropsychiatric and psychological disorders.

The association between physical activities combined with dietary habits and cardiovascular risk factors.

Objectives: The aim of this study was to investigate the association between physical activities combined with dietary habits and cardiovascular risk factors in adults from Nanjing, China. Methods: The cross-sectional survey conducted in 2017 involved a sample of 60 283 individuals aged ≥18 years in Nanjing municipality, China. The sampling method used was multistage stratified cluster sampling. The primary outcomes from multivariate logistic regression analysis with adjusted potential confounders were the relationships between physical activities combined with dietary habits and cardiovascular risk variables. Relative excess risk due to interaction (RERI), attributable proportion due to interaction (AP), and synergy index (S) were used to assess an additive interaction between dietary habits and physical activities. Results: After adjusting potential confounders, cardiovascular risk factors were significantly associated with the association of physical inactivity and unhealthy diet, with the highest odds ratios (ORs) for low density lipoprotein-cholesterol (HLDL-c) (1.64, 95% CI [1.47, 1.84]) and hypertension (1.55, 95% CI [1.46, 1.64]). Additive interactions between physical inactivity and unhealthy diet were found in on cardiovascular risk factors of higher low-density lipoprotein-cholesterol (HLDL-c) (S, 2.57; 95% CI [1.27, 5.21]), type 2 diabetes (T2D) (S, 1.96; 95% CI [1.23, 3.13]), dyslipidemia (S, 1.69; 95% CI [1.08, 2.66]) and hypertension (S, 1.46; 95% CI [1.12, 1.89]). Their RERI was 0.39 (95% CI [0.18, 0.60]), 0.22 (95% CI [0.09, 0.35]), 0.11 (95% CI [0.03, 0.19]) and 0.17 (95% CI [0.06, 0.28]), respectively. OR of being HLDL-c, T2D, hypertension and dyslipidemia in participants of physical inactivity and unhealthy diet was 24%, 15%, 11% and 8.3%, respectively. Multiplicative interaction was detected in obesity, hypertension, T2D and HLDL-c. Conclusion: An unhealthy diet and physical inactivity were strongly linked to cardiovascular risk factors. This study also showed that an unhealthy diet and physical inactivity combined to produce an additive effect on T2D, hypertension, HLDL-c, and dyslipidemia, suggesting a higher risk than the total of these factors, especially HLDL-c. Preventive strategies aimed at reducing cardiometabolic risks such as hypertension, T2D, HLDL-c, and dyslipidemia are necessary for targeting physical inactivity and unhealthy diet.

Self-reported exercise activity influences the relationship between coronary computed tomography angiographic finding and mortality.

AIM: Recent studies suggest that the application of exercise activity questionnaires, including the use of a single-item exercise question, can be additive to the prognostic efficacy of imaging findings. This study aims to evaluate the prognostic efficacy of exercise activity in patients undergoing coronary computed tomography angiography (CCTA). METHODS AND RESULTS: We assessed 9772 patients who underwent CCTA at a single center between 2007 and 2020. Patients were divided into 4 groups of physical activity as no exercise (n â€‹= â€‹1643, 17%), mild exercise (n â€‹= â€‹3156, 32%), moderate exercise (n â€‹= â€‹3542, 36%), and high exercise (n â€‹= â€‹1431,15%), based on a single-item self-reported questionnaire. Coronary stenosis was categorized as no (0%), non-obstructive (1-49%), borderline (50-69%), and obstructive (≥70%). During a median follow-up of 4.64 (IQR 1.53-7.89) years, 490 (7.6%) died. There was a stepwise inverse relationship between exercise activity and mortality (p â€‹< â€‹0.001). Compared with the high activity group, the no activity group had a 3-fold higher mortality risk (HR: 3.3, 95%CI (1.94-5.63), p â€‹< â€‹0.001) after adjustment for age, clinical risk factors, symptoms, and statin use. For any level of CCTA stenosis, mortality rates were inversely associated with the degree of patients' exercise activity. The risk of all-cause mortality was similar among the patients with obstructive stenosis with high exercise versus those with no coronary stenosis but no exercise activity (p â€‹= â€‹0.912). CONCLUSION: Physical activity as assessed by a single-item self-reported questionnaire is a strong stepwise inverse predictor of mortality risk among patients undergoing CCTA.

A comparative study on eating habits and mental health of Korean middle school students according to their bedtime across regions: using data from the 2020-2022 Korea Youth Risk Behavior Survey.

BACKGROUND/OBJECTIVES: The objective of this study was to compare dietary habits and mental health among middle school students in urban and rural areas based on bedtime, and to provide evidence supporting appropriate bedtime for Korean middle school students in relation to their healthy dietary habits and mental well-being. SUBJECTS/METHODS: The study population consisted of 25,681 second-year middle school students who participated in the Korea Youth Risk Behavior Survey in 2020-2022. Participants were asked about their bedtime and wake-up time during the past 7 days and were classified into five categories. The study compared the general characteristics, academic factors, dietary habits, and mental health of urban and rural students based on their bedtime. RESULTS: Bedtime was found to be later in the following order: urban female students, rural female students, urban male students, and rural male students. As bedtime got later, the rates of smoking and alcohol consumption increased. Students who went to bed before 11 p.m. had lower academic performance, while rural male students who went to bed after 2 a.m. had lower academic performance. Later bedtime was associated with increased smartphone usage, skipping breakfast, consuming fast food, and drinking carbonated beverages. Later bedtime was also associated with higher perceived stress levels, particularly among students who went to bed after 2 a.m., higher rates of suicidal ideation, experiencing sadness and despair, as well as the prevalence of clinically significant anxiety disorders. CONCLUSION: These results suggest that middle school students who go to bed too late have higher rates of smoking and alcohol drinking, as well as unhealthy eating habits, stress, suicidal ideation, sadness, and anxiety. Therefore, it is necessary to provide educational and social institutional support to promote adequate sleep for the health of adolescents.

Food Habits of Raccoon Dogs at An Agricultural Area in Shikoku, Western Japan.

The diet of raccoon dogs, which live in close proximity to agricultural fields in Matsuyama, western Japan, was studied throughout the year by the fecal analysis method (n = 114). Fruits were most important, accounting for 30-40% of the diet except in winter. Crops were next in importance, accounting for 10-30%. It was characteristic that the proportion of crops was greater and more stable than in other "satoyama" or rural areas in Japan. Crops included rice (Oryza sativa), wheat, sesame (Sesamum indicum), strawberries (Fragaria × ananassa), kiwi fruit (Actinidia chinensis var. deliciosa), ginkgo nuts (Ginkgo biloba), and persimmon (Diospyros kaki). Crops were important as the food for the raccoon dogs, but the use was not regarded as causing serious damage. Although wild boars (Sus scrofa), sika deer (Cervus nippon), and Japanese macaques (Macaca fuscata) were culled for pest control in the area, raccoon dogs were not culled. This may be a reason why the raccoon dog has coexisted with people in Japan.

Does compulsion explain addiction?

One of the leading drug addiction theories states that habits and the underlying neural process of a ventral to dorsal striatal shift are the building blocks of compulsive drug-seeking behaviour and that compulsion is the maladaptive persistence of responding despite adverse consequences. Here we discuss that compulsive behaviour as defined primarily from the perspective of animal experimentation falls short of the clinical phenomena and their neurobiological correlates. Thus for the human condition, the concept of compulsive habbits should be critically addressed and potentially revised.

The PRAMOS Study: PRostaglandin Analogues Monotherapy-Awareness Survey on Ocular Surface Involvement.

INTRODUCTION: Even though the local tolerance of prostaglandin (PG) analogues has improved drastically since the introduction of preservative-free (PF) eye drops, prescription patterns still vary widely among practitioners and between countries and could have an impact on the ocular surface of treated patients and, in consequence, their adherence. The aim of this study is to explore the prescribing patterns of PG analogues monotherapy in France and to evaluate their impact on ocular surface status. METHODS: This was a national multicenter cross-sectional observational study that was conducted by 18 glaucoma experts in France. Patients over 18 years of age and receiving monotherapy with topical PG analogues for the treatment of ocular hypertension and/or glaucoma, with no history of prior glaucoma surgery, were consecutively selected from the glaucoma outpatient clinics of participating physicians and underwent an ocular surface examination. RESULTS: A total of 344 eyes of 344 patients were enrolled between November 2022 and November 2023. Prescribed PG monotherapy was PF in 271 (78.7%) patients. Clinical history and ocular surface evaluation indicated that 79.4% of the study population (n = 273) presented with at least one symptom or clinical sign of dry eye and that three patients out of four had an unstable tear film. Subgroup analysis comparing preserved and PF PG analogues showed a higher prevalence of conjunctival hyperemia and corneal staining in the preserved group. Multivariate analysis identified conjunctival hyperemia as consistently associated with preservative use (odds ratio = 7.654; p = 0.003 for moderate conjunctival hyperemia). CONCLUSIONS: This study highlights the growing trend toward PF PG analogue prescriptions by specialists in France. However, ocular surface issues remain prevalent, impacting patient adherence and treatment efficacy. Comprehensive ocular surface examinations are crucial in glaucoma management to enhance long-term tolerance, compliance, and overall treatment success.

Eating habits and sleep quality in individuals with type 1 diabetes on continuous glucose monitoring and insulin pump.

BACKGROUND AND AIMS: Sleep disorders are bidirectionally linked with eating behaviors and glucose metabolism, which could be clinically relevant in type 1 diabetes (T1D). We investigated the relationship between dietary habits and sleep quality in individuals with T1D on insulin pumps and continuous glucose monitoring (CGM). METHODS AND RESULTS: In a cross-sectional study, dietary habits (7-day food diary, EPIC questionnaire) and sleep quality (Pittsburgh Sleep Quality Index questionnaire) were assessed in 59 men and 58 women with T1D, aged 19-79 years, using CGM and insulin pump. Differences in dietary habits and blood glucose after dinner (6 h) between participants differing in sleep quality, sleep duration, and sleep onset latency were evaluated. Bad Sleepers (n = 81) were twice as prevalent as Good Sleepers (n = 36) and had a significantly higher intake of fat than Good Sleepers (dinner: 30.7 ± 10.7 vs. 24.0 ± 10.5 g, p = 0.004). Short sleepers had a significantly higher usual intake (g/1000 kcal) of coffee and tea (90.4 ± 71.7 vs. 62.0 ± 35.6), alcoholic (47.8 ± 51.1 vs. 28.9 ± 31.5) and carbonated beverages (21.8 ± 38.1 vs. 9.3 ± 17.2) (p < 0.05 for all) than Long Sleepers. Long Sleep Onset Latency was associated with a significantly higher fat intake at dinner (41.8 ± 7.4 vs. 38.1 ± 9.1 % total energy, p = 0.029) than Short Sleep Onset Latency. No significant differences in post-dinner blood glucose levels were detected between participants with good or bad sleep quality. CONCLUSION: Sleep disruption is common in T1D and is associated with unhealthy dietary choices, especially at dinner, independently of post-dinner blood glucose control.

Mechanism of muscle atrophy in a normal-weight rat model of type 2 diabetes established by using a soft-pellet diet.

Dietary factors such as food texture affect feeding behavior and energy metabolism, potentially causing obesity and type 2 diabetes. We previously found that rats fed soft pellets (SPs) were neither hyperphagic nor overweight but demonstrated glucose intolerance, insulin resistance, and hyperplasia of pancreatic ß-cells. In the present study, we investigated the mechanism of muscle atrophy in rats that had been fed SPs on a 3-h time-restricted feeding schedule for 24 weeks. As expected, the SP rats were normal weight; however, they developed insulin resistance, glucose intolerance, and fat accumulation. In addition, skeletal muscles of SP rats were histologically atrophic and demonstrated disrupted insulin signaling. Furthermore, we learned that the muscle atrophy of the SP rats developed via the IL-6-STAT3-SOCS3 and ubiquitin-proteasome pathways. Our data show that the dietary habit of consuming soft foods can lead to not only glucose intolerance or insulin resistance but also muscle atrophy.

Knowledge and eating habits regarding functional food among adults.

Background: Functional food is a key element in the prevention and treatment of many diseases. The ingredients it contains, such as phytosterols that lower cholesterol, also have a preventive effect on type 2 diabetes, atherosclerosis and heart attack. Phenolic compounds have antioxidant, anti-inflammatory and antiviral properties. Xylo-oligosaccharides control insulin levels, and fibre lowers blood pressure, potentially reducing insulin resistance. These beneficial properties mean that there is an increasing interest in this kind of food. Objective: The aim of the study was to assess the state of knowledge and behaviour regarding functional food among adults and to answer the question whether there are differences between the state of knowledge and behaviour of women and men. Material and methods: The survey was conducted among 301 people, including 181 women and 120 men. The research tool was an original survey questionnaire. Results: The definition of functional food is known to 42.5% of people (47.5% of women and 35% of men), while the definition of prebiotic is known to 41.9% of people (43.1% of women and 40.0% of men). For 56.2% of respondents, the factor encouraging the consumption of functional food was a healthy lifestyle, and for 54.7% of them, the product composition was the main purchase criterion. Among functional products, cereals or muesli were most often consumed for breakfast by 35% of men and 55.8% of women, 42.5% of men and 33.7% of women were eaten oils for lunch. For dinner they most often consumed fruit teas, herbal teas, herbal mixtures, this answer was given by 25.8% of men and 29.8% of women. Conclusions: Knowledge of functional foods is unsatisfactory, and no differences in the knowledge of women and men have been observed. Consumption of functional food is generally low, and no differences in consumption have been observed between women and men.

Genetic correlation and Mendelian randomization analyses support causal relationships between dietary habits and age at menarche.

Dietary habits are essential in the mean age at menarche (AAM). However, the causal relationship between these factors remains unclear. Therefore, this study aimed to elucidate the genetic relationship between dietary habits and AAM. Genetic summary statistics for dietary habits were obtained from the UK Biobank. GWAS summary data for AAM was obtained from the ReproGen Consortium. Linkage disequilibrium score regression was used to test genetic correlations between dietary habits and AAM. The Mendelian randomization (MR) analyses used the inverse-variance weighted method. Genetic correlations with AAM were identified for 29 candi-date dietary habits, such as milk type (skimmed, semi-skimmed, full cream; coefficient = 0.2704, Pldsc = 1.13 × 10-14). MR evaluations revealed that 19 dietary habits were associated with AAM, including bread type (white vs. any other; OR 1.71, 95% CI 1.28-2.29, Pmr = 3.20 × 10-4), tablespoons of cooked vegetables (OR 0.437, 95% CI 0.29-0.67; Pmr = 1.30 × 10-4), and cups of coffee per day (OR 0.72, 95% CI 0.57-0.92, Pmr = 8.31 × 10-3). These results were observed to be stable under the sensitivity analysis. Our study provides potential insights into the genetic mechanisms underlying AAM and evidence that dietary habits are associated with AAM.

Multipronged effects of increased screen time on the nutritional imbalance: A cross-sectional study of students of Amritsar aged 6-16 years.

Background: Intense marketing of fast-food items impacts the eating habits among children and adolescents. Various studies suggest that increased screen time leads to increased fast-food consumption and decreased sleep duration, both of which are linked to obesity in growing age. Objectives: To assess screen time and dietary habits among the study group and to estimate their effect on sleep deprivation and obesity. Methods: This cross-sectional study was conducted from January 2019 to December 2019 in three schools in Amritsar selected by lottery method of simple random sampling. Out of 4,226 students, 355 overweight and obese students were interviewed regarding their dietary habits. An informed written assent was taken from the mothers. The information was collected on a semi-structured, pre-designed questionnaire by interviewing the mothers of students between 6 and 11 years of age and the students of 12-16 years. Results: 94.4% of students preferred fast foods to regular meals and 58.3% were in the habit of skipping breakfast. 59.4% had a history of daily intake of fast foods while 76.1% had a habit of consuming fast foods while watching television. Only 31.7% had an adequate sleeping pattern of 9-11 hours and 79.7% of the students had a screen time of over 3 hours. Conclusions: More the screen time, the more the chances of missing meals. Being awake for a long odd time leads to increased consumption of foods/snacks furthermore. Regarding the harmful effects of fast foods, the source of information was from schools, but only 41.4% were aware about these effects.

Changes in eating habits and lifestyle during the first year of the COVID-19 pandemic across metropolitan regions in Brazil and Germany: A survey-based cross-sectional study.

COVID-19 caused profound societal changes to cope rapidly with the new circumstances. The food market changed its quantity, quality, form, and frequency dynamics. Consequently, food-eating habits and lifestyles like physical exercise likely experienced changes. An online-based survey was conducted between June 2020 and January 2021 in the metropolitan regions of Rhine Ruhr Metropolis (RRM), Greater São Paulo (GSP), other metropolitan regions in São Paulo state (oMRSP), other Brazilian metropolitan regions (oBRMR), and the remaining urban areas in both countries (oUA), representing different contexts of Brazil and Germany. We assessed self-reported changes in physical activity level, diet quality, self-reported eating habits, and buying groceries during the first year of the pandemic. In Germany, indoor and outdoor activities increased for 34% of the respondents, while in Brazil, there was a decrease in physical activity for 50% of the participants. The Healthy Eating Index (HEI) scored higher among Brazilians (16.8) than Germans (15.2) on a 0-29 HEI scale. Increased awareness of healthy and sustainable eating habits was observed in GSP (0.7), oMRSP (0.63), oBRMR (0.7), and oUA (0.68) on a scale from no change (0) to change (1). In RRM, an increase in convenience foods was noticed (0.86). Participants reported discomfort with food purchasing due to hygiene measures and avoided going to the supermarket (0.7 on average in Brazil and 0.58 for females using the same 0-1 scale). Also, food supply at the grocery shops was reported to be often unavailable and in lower quantities. A real-time assessment of self-reported changes in eating habits and lifestyle during the lockdown in 2020 in different contexts is insightful for rethinking strategies to improve conditions in the post-COVID-19 era and prepare for future pandemics.

Compensatory health beliefs in women in the first, second and third trimester of pregnancy.

BACKGROUND: Compensatory health beliefs may serve as one of many self-regulatory strategies that individuals employ to maintain healthy lifestyles. Past research with samples from a general population has shown, however, that compensatory beliefs are ineffective in this regard and may even lead to inaction in future health-related behaviors such as eating healthily or being active. To better understand this phenomenon, in the present study, changes in compensatory health beliefs regarding various life domains were examined in a group of pregnant women. PARTICIPANTS AND PROCEDURE: In a longitudinal study design, 166 women completed questionnaires in the first (t1), the second (t2), and the third (t3) trimester of their pregnancies. We assessed the level of their self-control as a trait (t1, t2, t3), compensatory health beliefs (t1, t2, t3), and unhealthy snacking (t3). RESULTS: As predicted, self-control as a trait decreased and the levels of compensatory beliefs increased over time. A linear mixed effects analysis showed that self-control was the best predictor of compensatory beliefs in the third trimester. Finally, compensatory health beliefs in the third trimester mediated the effect of self-control at the beginning of pregnancy on unhealthy snacking in the third trimester. CONCLUSIONS: It appears important to support pregnant women in opting for constructive self-regulatory strategies, especially in their final trimesters, when coping resources are exhausted by the challenges of this period.

Dietary habits among 177091 Greek schoolchildren by age, sex, weight status, region, and living area. A cross-sectional study.

BACKGROUND: This study aimed to investigate the dietary habits, from early childhood to adolescence, among participants from all regions of the country and living areas (rural/urban) and to assess potential associations between dietary habits and obesity, in both sexes. METHODS: Population data were derived from a cross-sectional, health survey on a representative sample of 177091 children aged 6 to 18 years. Dietary habits were considered via a self-completed questionnaire (KIDMED index). Trained investigators assessed anthropometric data. RESULTS: KIDMED scores were 6.7±2.4 and 6.8±2.3 for boys and girls, respectively, while a percentage of almost 10% of the total study population had insufficient dietary habits. Dietary habits peaked around age 11 and then gradually worsened until the end of adolescence, among both sexes, with an annual trend equal to -0.28±0.02 (p<0.001), for boys and 0.31±0.03, (p<0.001), for girls. Overweight/obese schoolchildren presented higher percentages in all unhealthy dietary habits (e.g. skipping breakfast, going often to a fast-food restaurant, and consuming a lot of sweets) than normal-weight ones (all p-values<0.001). Dietary habits did not noteworthy differ by area of living, i.e. urban versus rural, of participants, in both sexes. Also, no noticeable differences in the values of the KIDMED index were found among all regions of Greece, with the highest values in Attica and Crete, in both sexes. CONCLUSIONS: As Greek schoolchildren do not fully adopt the traditional cardio-protective Mediterranean diet, it could be helpful to provide certain recommendations, especially for adolescents, to decrease the risk for future adverse health consequences.

Cross-sectional interactive associations of physical activity and sedentary behaviour with physical capacity across adulthood.

BACKGROUND: The way physical activity (PA) and sedentary behaviour (SB) independently and interactively modify the age-related decline in physical capacity remains poorly understood. This cross-sectional study investigated the independent and interactive associations of PA and SB with physical function and performance throughout the adult life course. METHODS: Data from 499 community-dwelling adults (63% female) aged 20-92 years, involved in the INSPIRE Human Translational Cohort, were used in this cross-sectional study. Daily time spent on moderate-to-vigorous PA (MVPA, min/day) and SB (h/day) was measured with activPAL triaxial accelerometers. Physical function and performance were assessed through the measurement of the 4-m usual gait speed (m/s), handgrip strength (kg), lower-limb strength (isokinetic knee extension torque, N·m), estimated lower-limb power (five-time chair-rise test performance, s) and cardiorespiratory fitness (V̇O2max, mL/kg/min). Confounder-adjusted multiple linear and curvilinear regressions were performed to investigate how MVPA, SB and their interactions were associated with the physical outcomes (all square root-transformed except gait speed) throughout the adulthood spectrum. RESULTS: Interaction analyses revealed that the combination of higher levels of MVPA with lower levels of SB favourably reshaped the negative relationship between handgrip strength and age (age2 × SB × MVPA: B = -7E-08, SE = 3E-08, P < 0.05). In addition, higher levels of MVPA were independently associated with an improved age-related profile in gait speed (age2 × MVPA: B = 3E-06, SE = 1E-06, P < 0.05), chair-rise performance (age × MVPA: B = -9E-05, SE = 4E-05, P < 0.05) and V̇O2max (MVPA at 21 years: B = 3E-02, SE = 7E-03, P < 0.05; age × MVPA: B = -5E-04, SE = 2E-04, P < 0.05). Conversely, the detrimental association of age with lower-limb muscle strength (age × SB: B = -1E-04, SE = 6E-05, P < 0.05) and chair-rise performance (age × SB: B = 1E-05, SE = 7E-06, P < 0.05) was exacerbated with increasing duration of SB, independently of MVPA. Supplementary analyses further revealed that some of these associations were age and sex specific. CONCLUSIONS: This cross-sectional study demonstrated that reduced sedentary time and increased activity duration were independently and synergistically associated with an attenuated age-related loss in physical capacity. These findings need to be confirmed with longitudinal data but encourage both adopting an active lifestyle and reducing sedentary time as preventive measures against physical aging.

Longitudinal change of energy expenditure, body composition and dietary habits in Progressive Supranuclear Palsy patients.

INTRODUCTION: Alterations in metabolic status, body composition, and food intake are present in all neurodegenerative diseases. Aim of this study was to detect the progression of these changes in Progressive Supranuclear Palsy (PSP). METHODS: We conducted a longitudinal study of 15 patients with PSP. The assessments were performed at baseline (T0) and after 7(IQR = 5) months of follow-up (T1). We collected anthropometric measures including body weight, height, body mass index and waist circumference, metabolic parameters through indirect calorimeters, body composition using bioimpedance analysis, and dietary habits with a validated questionnaire. PSP-rating scale (PSP-rs) was used to evaluate disease severity and dysphagia. RESULTS: The majority of patients (66.66%) presented PSP-Richardson Syndrome and 33.33% the other variant syndromes of the disease. At T1 there was a decrease in intake of total daily calories (p < 0.001), proteins (p < 0.001), fibers (p = 0.001), calcium (p = 0.008), iron (p < 0.001), zinc (0.034), vitamin E (p = 0.006) and folates (p = 0.038) compared to T0. No other changes were found. As for T1 data, no significant differences were shown according to disease phenotypes or the presence of clinically significant dysphagia for solids. CONCLUSIONS: Within a mid-term follow up, PSP patients presented reduced caloric and proteins intake regardless the presence of dysphagia. The PSP-rs is likely not adequate to assess dysphagia, which should be investigated by specific clinical scales or instrumental examinations. With the goal of maintaining adequate nutritional status, the administration of protein and vitamin supplements should be considered even in the absence of dysphagia evidenced by the rating scales.

Sleep Habits, Academic Performance and Health Behaviors of Adolescents in Southern Greece.

Adolescents often experience insufficient sleep and have unhealthy sleep habits. Our aim was to investigate the sleep patterns of secondary education students in Heraklion, Crete, Greece and their association with school performance and health habits. We conducted a community-based cross-sectional study with 831 students aged 13-19 years who completed an online self-reported questionnaire related to sleep and health habits. The data are mostly numerical or categorical, and an analysis was performed using t-tests, chi-square tests and multiple logistic regression. During weekdays, the students slept for an average of 7 ± 1.1 h, which is significantly lower than the 7.8 ± 1.5 h average on weekends (p < 0.001). Nearly 79% reported difficulty waking up and having insufficient sleep time, while 73.8% felt sleepy at school at least once a week. Having sufficient sleep time ≥ 8 h) was positively correlated with better academic performance (OR: 1.48, CI: 1.06-2.07, p = 0.022) and frequent physical exercise (never/rarely: 13.5%, sometimes: 21.2%, often: 65.3%; p = 0.002). Conversely, there was a negative correlation between adequate sleep and both smoking (OR: 0.29, CI: 0.13-0.63) and alcohol consumption (OR: 0.51, CI: 0.36-0.71, p = 0.001). In conclusion, this study shows that students in Heraklion, Crete frequently experience sleep deprivation, which is associated with compromised academic performance, reduced physical activity and an increased likelihood of engaging in unhealthy behaviors like smoking and alcohol consumption.
