Knowledge About Sleep, Sleep Hygiene, and Sleep Behaviors of Paralympic Athletes.

CONTEXT: Understanding Paralympic athletes' perspectives on the importance of sleep is the first step toward developing effective sleep hygiene (SH) strategies. We aim to describe and compare the knowledge about SH and sleep behaviors practiced by medalists and nonmedalists Paralympic athletes at the Tokyo 2020 Paralympic Games and between sexes (female vs male), identify whether the coaching staff encourages SH, and the perspective of these athletes on the importance of SH. METHODS: 98 Paralympic athletes responded to the Sleep Beliefs Scale and the Athlete Sleep Behavior Questionnaire-BR. RESULTS: Medalists (68%) and nonmedalists (78%) Paralympic athletes had low knowledge about SH (60% vs 55%; P = .20), with no difference between groups. The Athlete Sleep Behavior Questionnaire-BR score (48.7 [5.9]) for all Paralympic athletes (n = 98) indicated high practice of maladaptive sleep behaviors. Male athletes had significantly worse sleep behaviors than female athletes (49.1 [6.0] vs 39.5 [7.2]; P < .01) and less knowledge about behaviors that can affect sleep (64% vs 72%; P < .05), 26% of Paralympic athletes considered SH practices necessary, and the frequency of coaching staff encouraging SH was higher among medalists Paralympic athletes compared to nonmedalists athletes (29% vs 13%, P = .04). CONCLUSIONS: Most Paralympic athletes have inadequate sleep behaviors and knowledge about SH. There was no difference between knowledge about SH and sleep behaviors between medalists and nonmedalists Paralympic athletes, although medalists athletes were more encouraged to practice SH. Male Paralympic athletes had worse sleep behaviors and worse knowledge about SH than female athletes.

Hábitos alimentarios saludables en estudiantes de la Sociedad Científica Estudiantil Jóvenes por la Salud

Se realizó una investigación educacional en el preuniversitario Inés Luaces Sánchez del municipio Camagüey en el periodo comprendido de mayo a noviembre de 2023 con el objetivo de diagnosticar los hábitos alimentarios saludables en los estudiantes de la Sociedad Científica Estudiantil Jóvenes por la Salud. Dentro de los métodos empíricos fueron utilizados la revisión bibliográfica para obtener información sobre el tema a través de bases de datos como Science Direct, PubMed, Medline y SciELO y el cuestionario. Se evidenció que tienen un consumo deficiente de pescado, frutas y vegetales y un elevado consumo de azucares, grasas y pan. Se concluye que los estudiantes poseen insuficientes hábitos alimentarios saludables y son limitados sus conocimientos acerca de los beneficios de los alimentos orgánicos, dentro de estos las setas comestibles.

An educational research was carried out at the Inés Luaces Sánchez high school in the municipality of Camagüey in the period from May to November 2023 with the objective of diagnosing healthy eating habits in the students of the Young People for Health Student Scientific Society. Among the empirical methods, the bibliographic review was used to obtain information on the topic through databases such as Science Direct, PubMed, Medline and SciELO and the questionnaire. It was evident that they have a deficient consumption of fish, fruits and vegetables and a high consumption of sugars, fats and bread. It is concluded that students have insufficient healthy eating habits and their knowledge about the benefits of organic foods, including edible mushrooms, is limited.

Regular Family Meals Associated with Nutritional Status, Food Consumption, and Sedentary and Eating Behaviors of Brazilian Schoolchildren and Their Caregivers.

The influence of family meals on nutrition and health for families has been understudied, especially in low- and middle-income countries. We aimed to analyze associations between regular family meals and body mass index (BMI), food consumption, eating, and sedentary behaviors among Brazilian schoolchildren and their caregivers. A cross-sectional study was conducted with 1887 Brazilian schoolchildren aged 6-11 years and their caregivers. Caregivers provided sociodemographic data, their child's weight and height, and the frequency of family meals. Schoolchildren provided data on gender and silhouette scale. Both provided their food consumption, eating, and sedentary behavior data. Associations between regular family meals and BMI, ultra-processed food consumption, and dietary diversity were assessed through multivariate logistic regression models. Correlations of regular family meals with eating and sedentary behaviors were assessed using Pearson chi-square. Regular family meals were frequent (86.6%), and they were associated with less unhealthy BMI in caregivers (AOR: 0.74; 95%CI: 0.5-0.9), as well as higher dietary diversity in caregivers (AOR: 1.66; 95%CI: 1.0-2.7) and in schoolchildren (AOR: 1.78; 95%CI: 1.4-2.3). The coexistence of high dietary diversity and both low ultra-processed food consumption (AOR: 1.45; 95%CI: 1.0-2.1) and healthy BMI (AOR: 1.41; 95%CI: 1.0-1.9) in children was associated with regular family meals. Regular family meals were correlated with healthy eating behaviors in child-caregiver dyads (p < 0.002) and with sedentary behavior in caregivers (p = 0.019). Our findings underscore regular family meals as a protective factor against malnutrition among Brazilian families.

Are Argentinians ready for plant-based meat alternatives? A case study on awareness and willingness for consumption.

Meat alternatives' popularity is increasing worldwide. Nevertheless, the attitudes and motivations underpinning their adoption still evolve and may differ by region. In Argentina, where meat consumption per capita is among the highest globally, the market for plant-based meat alternatives (PBMAs) is just beginning to develop. Few reports attempt to explain the behavior of the Argentinian population regarding these products. This study explored the knowledge, attitudes, and perceptions of meat analogues and hybrid products through a national online survey (N = 2339). Also, barriers and drivers to their consumption as well as the target segments were identified. Participants were classified as omnivores 73.8%, flexitarians 19.5%, vegetarians 6%, and vegans 0.7%. Despite the significant lack of awareness about PBMAs, there is a strong willingness to adopt them, with females, younger respondents, and those with lower incomes more open to these options. The main drivers for consumption were health concerns, animal welfare, and environmental awareness. Familiarity was a key factor influencing the adoption, as evidenced by the openness of well-informed omnivores. Lack of available options represented the main limitation for consumption and distrust regarding their origin and sensory appeal were the primary reasons for rejection. This study reveals a potential market for PBMAs in Argentina, highlighting that guaranteeing nutritional and sensory quality is crucial. Educating consumers is also essential for their widespread acceptance.

Glaucoma and dietary intake: a scoping review.

Introduction: Studies have suggested that dietary intake may influence the incidence and progression of open-angle glaucoma. However, dietary modification is not usually included in the clinical management of glaucoma. The aim of this scoping review was therefore to map the evidence and determine the nature and extent of research done on "diet and glaucoma" and identify any gaps in this area of scholarship. Materials and methods: A comprehensive search of academic literature was conducted from two relevant electronic databases: PubMed and ScienceDirect. Primary studies that explored the relationship between dietary intake and glaucoma were included if the principal exposure was "diet" and if dietary habits were assessed with dietary questionnaires. The glaucoma outcomes of interest were visual field, retinal nerve fibre layer and/or optic nerve head features. Results: Nineteen studies were included in the final qualitative synthesis. The dates of publication ranged from 2003 to 2023. About 80% of the studies found some significant associations between glaucoma and dietary intake. However, most studies (95%) were observational, i.e., 7 (37%) used a cross-sectional design, 10 (53%) used a prospective cohort design; and 1 (or 5%) used a nested case-control study design. Only 1 study (or 5%) used a randomized intervention trial. Furthermore, while all studies investigated dietary intake with questionnaires, only 2 studies (or 11%) went further to include assessment of nutritional biomarkers. Conclusion: Although miscellaneous evidence supports the concept that diet may play a role in glaucoma, most data are unfortunately observational without proven causality, reporting associations from subjective dietary questionnaires. More well-designed studies are required, especially randomized controlled trials that can prove causality.

Variations in Some Features of Oral Health by Personality Traits, Gender, and Age: Key Factors for Health Promotion.

Background: Oral diseases remain among the most common non-communicable diseases worldwide, affecting almost half of the world's population. This is partly because there has been a separation of the mouth from the rest of the body and human health, and psychological aspects such as personality, thoughts, and emotions are not taken into account in the dental office. The objective was to analyze the relationship between oral health conditions and personality traits in adult patients who underwent dental treatment at the Center for Health Studies and Services. Methods: This was a descriptive, observational, and correlational study, carried out at the Center for Health Studies and Services. A total of 184 patients who attended the dentistry area in the period from October 2022 to May 2023 participated in the study, of which 59.78% were women and 40.21% men. The age of the population was 18 to 79 years, with the age range of 21-40 years being the most prevalent (48.37%). Results: The results show that although the hygiene of the population treated was good (0.77 ± 0.79) and that the perception of oral health was positive (14.34 ± 9.43), the means and percentages of oral pathologies and parafunctional habits were high (i.e., DMFT: 9.98 ± 5.40; attrition: 87.50%; onychophagia: 45.10%). It is noteworthy that both the correlation, network, multiple line regression, and logistic regression analyses showed associations of the personality, gender, and age variables with a history of caries and oral hygiene as well as with parafunctional habits. Conclusions: Therefore, variations in both the personality and the age and gender of the patients treated have repercussions on oral health conditions, which can be used in the prevention of oral diseases and in health promotion.

La importancia del sueño en los adolescentes: impacto de variables sociodemográficas y de factores personales / The Importance of Sleep in Adolescents: Impact of Sociodemographic Variables and Personal Factors

Resumen Objetivo: Ante la escasez de investigaciones que traten de manera conjunta el conocimiento, la calidad y la higiene del sueño en el adolescente, el objetivo del presente estudio es analizar las diferencias y las relaciones que existen entre estas variables en función de características sociodemográficas y personales. Método: A través de los instrumentos Sleep Beliefs Scale (SBS), Spanish Adolescents and Young Adults Pittsburgh Sleep Quality Index (AYA-PSQI-S) y Adolescents Sleep Hygiene Scale Revied (ASHSr), se midieron las características del sueño de 140 estudiantes (M = 16,75; DE = 0,75). Resultados: El 89,3% de los adolescentes presentaban problemas de sueño, subyacentes de la mejorable higiene del sueño por parte del 62,2% y de un escaso conocimiento general del sueño. El sexo femenino y el alumnado en cursos superiores presentaron mayores problemas para conciliar el sueño, somnolencia y una baja gestión cognitiva-emocional (p < 0,05). La higiene del sueño (β = - 0,344), la edad (β = 0,154) y el autoconcepto (β = -0,349) son los factores que predijeron significativamente (p < 0,05) la calidad del sueño del adolescente. Conclusiones: La adquisición de una adecuada higiene del sueño se vuelve fundamental para mejorar la calidad del descanso y la funcionalidad diurna en adolescentes, destacando su importancia, sobre todo, en niveles académicos avanzados y en el caso específico de las mujeres.

Abstract Objective: Given the scarcity of research addressing the intersection of knowledge, sleep quality, and hygiene among adolescents, the primary objective of this study is to analyse the variations and correlations among these variables based on socio-demographic and personal characteristics. Method: The Sleep Beliefs Scale (SBS), the Spanish Adolescents and Young Adults Pittsburgh Sleep Quality Index (AYA-PSQI-S), the Adolescents Sleep Hygiene Scale Revied (ASHSr) were used to measure the sleep characteristics of the 140 Spanish students (M = 16,75; SD = 0,75). Results: Sleep problems were found in 89,3% of the adolescents, underlying poor sleep hygiene in 62,2% and poor general sleep knowledge (SBS = 12,04). Females and students in higher grades presented greater problems in falling asleep, sleepiness, and poor cognitive-emotional management (p < 0,05). Sleep hygiene (β = - 0,344), age (β = 0,154), and self-concept (β = -0,349) were the factors that significantly (p < 0,05) predicted adolescent sleep quality. Conclusions: The acquisition of proper sleep hygiene becomes crucial to enhance the quality of rest and daytime functionality in adolescents, emphasizing its significance, especially in advanced academic levels and specifically in the case of females.

Dysmenorrhea and Premenstrual Syndrome in Association with Health Habits in the Mexican Population: A Cross-Sectional Study.

BACKGROUND: Dysmenorrhea and premenstrual syndrome (PMS) are common disorders in the Mexican population, but these are usually underdiagnosed and under-treated, impacting women's quality of life. Adequate health habits have been reported as precursors of decreasing dysmenorrhea symptoms. However, few studies assess their impact on PMS. AIM: This study aims to evaluate dysmenorrhea and premenstrual syndrome in association with health habits in the Mexican population. METHODS: To assess the impact of health habits on menstruation symptoms a validated survey was conducted in 1679 adult females aged ≥18 years. The survey collected data on participants' dysmenorrhea, PMS, and their health habits. RESULTS: The analysis showed that physical activity duration, changes in eating habits (increases in salty or sugary foods) during menstruation, and oversleeping habits predict increases in dysmenorrhea and PMS. In contrast, an active sexual life, relaxing physical activity, and adequate sleep hours during menstruation seem to decrease the symptoms. CONCLUSIONS: We conclude that adequate health habits and addressing early gynecological conditions might regulate dysmenorrhea and PMS.

Analysis of Google users' interests in information about pacifiers: an ecological digital study.

PURPOSE: To determine the interests of Google users from different countries about pacifier-related information over time, through a quantitative and qualitative analysis. METHODS: This infodemiology longitudinal retrospective ecological study investigated pacifier-related computational metadata from 22 countries using Google Trends platform. Initially, Relative Search Volume (RSV) time series data and their respective main queries were collected employing the topic "pacifier - subject" as the search strategy from January 2004 to June 2024, considering all categories. Data were then analyzed through seasonal decomposition to determine the trend, seasonal, and residual components of the collected time series using Python 3 programming libraries in a Google Collaboratory interface. Additionally, Mann-Kendall tests were performed to access the significance level of trends observed from the seasonal decomposition. Finally, the queries were qualitatively evaluated to identify the main subjects related to users' interests. Statistical significance was determined with p values < 0.05. RESULTS: In general, RSV time series curves exhibited upward trends in all analyzed countries over the years, with significance levels demonstrated by the Mann-Kendall tests. Moreover, queries often centered around types of pacifiers, encompassing searches specifically for certain commercial brands. Some searches concerning newborn and baby care were also observed, particularly highlighting breastfeeding practices. CONCLUSION: Google users have shown an increasing interest in pacifier-related topics. These data can help understand the needs and concerns of parents and caregivers regarding pacifier use, ultimately supporting the development of effective educational strategies.

The transformative journey of community health workers in implementing a lifestyle intervention in Brazil: A qualitative study.

Introduction: Community health workers (CHWs) stand as critical frontline agents within the Brazilian healthcare system. In this qualitative study, we examined the impact of a community-based behavioral change intervention spearheaded by CHWs. Methods: The intervention focused on promoting healthy behaviors - physical activity, nutrition, and emotional well-being - among individuals aged 50 and older living in a rural community in Brazil. The intervention was designed, implemented, and evaluated in close collaboration with CHWs and local administrators. The implementation of the intervention unfolded in two waves, each lasting 12 months. Interviews with CHWs, health administrators, and intervention participants conducted at post-intervention and 6-year follow-up centered on CHWs as delivery agents and examined the implementation of the intervention in primary care contexts around adoption, implementation, and long-term maintenance. Results: Inductive analysis revealed four themes that highlight CHWs' motivation to take active roles in health promotion and overcoming challenges such as unfamiliarity with new roles or limited training. In addition, enhanced community bonds, job satisfaction, and trust in CHWs gained through the intervention, empowered CHWs to realize their potential and importance. Another important area relates to the CHWs' ability to leverage their deep community ties and cultural insights to enhance the intervention's significance. CHWs' participation in the program also led to personal benefits and self-care practices, setting an example for the community they serve. Conclusions: This study underscores the positive impact of a community-based intervention led by CHWs. Such programs have the potential for nationwide dissemination, leveraging the CHWs' widespread presence and deep community integration.

Influence of unhealthy diet and sedentary behavior on the oral health-related quality of life of 12-year-old Brazilian adolescents.

This study analyzed the factors associated with the oral health-related quality of life (OHRQOL) of 12-year-old adolescents and their relationship with unhealthy eating and sedentary behavior. Data were collected from 615 adolescents from the five largest cities in Mato Grosso do Sul, Brazil. The theoretical framework of the social determinants of oral health guided all analyses and the measurement instrument was OIDP (impact of oral health on daily performance). Multilevel logistic and negative binomial regressions were performed to test the association of OHRQOL with unhealthy eating, sedentary behavior, sociodemographic characteristics and health behaviours. Considering the sample weights, 43% of the adolescents reported some impact on OHRQOL. In the adjusted models, higher consumption of unhealthy foods (moderate and high) was associated with a prevalence of impact on OHRQOL [OR = 3.59 (95%CI 1.99; 6.46)] and higher OHRQOL severity [RR = 2.05 (95%CI 1.43; 2.94)] compared to their counterparts. Sedentary behaviour was associated with the prevalence of impact on OHRQOL [OR = 1.52 (95%CI 1.22; 1.89)] and greater severity [RR = 1.21 (95%CI 1.07; 1.37)] compared to their counterparts. Unhealthy food consumption and sedentary behavior were associated with OHRQOL. Intersectoral health public policies for healthy eating and for reducing sedentary behavior on the internet and electronic games can help in the quality of life of adolescents.

Hard-to-reach communities in the rural Ecuador: A qualitative perspective on dietary habits and physical activity.

While many studies focus on urban areas, it's vital to understand health-related behaviours in rural communities. This paper aims to explore the factors that influence dietary habits and physical activity from the perspective of men and women of different ethnic groups living in a hard-to-reach rural area in Ecuador. We conducted 5 focus groups with 37 participants (26 women) from diverse cultural and ethnic backgrounds in marginalized communities in Esmeraldas. The thematic analysis showed environment and culture shape dietary habits and physical activity, influenced by taste preferences, economic factors, and societal norms, with gender roles and beauty standards playing significant roles.

Food consumption and mental health in children and adolescents: A systematic review protocol.

Mental illnesses are prevalent among children and adolescents worldwide and may be associated with food consumption. This protocol aims to evaluate the association between food consumption and mental health in children and adolescents through a systematic review and meta-analysis. The electronic search will include keywords related to childhood, adolescence, mental health issues (e.g., anxiety, stress, depression), and food consumption (e.g., in natura or minimally processed foods and ultra-processed foods ultra-processed foods), verified using MeSH terms. The systematic review will follow the PRISMA-2020 guidelines, employing the PECOS strategy, and will include quantitative observational and mixed-methods studies. A search will be conducted in the following databases: Scopus, CINAHL, SPORTDiscus, LILACS, Web of Science, APA-PsycArticles, PubMed/Medline, and EMBASE. Identifying the association between mental health and food consumption will contribute to the development of preventive and intervention strategies aimed at improving the health and well-being of children and adolescents. The analysis of the data will provide results on how psychological factors are linked to the consumption of various food groups, implying the updating of public policies. These guidelines can assist managers and researchers in creating effective interventions to promote mental health and healthy eating behaviors, ultimately leading to long-term positive impacts on public health.

Using the Complex Network Model to Associate Nutritional, Psychological, and Physical Parameters and Aspects of Sleep with Depression Symptoms.

Background/Objectives: Major depressive disorder is a significant public health concern linked to factors such as a low-quality diet, a sedentary lifestyle, and poor sleep quality, all of which contribute to its development; nevertheless, the existing literature lacks a comprehensive framework to effectively integrate these interrelated influences. Methods: To address this gap, we conducted a questionnaire-based study involving 411 individuals aged 18 to 74 and employed a weighted complex network model to clarify the associations among nutritional factors, physical activity levels, psychological parameters, and sleep profiles and depression. In addition to constructing networks that encompass distinct subgroups based on general context, sex differences (female vs. male), and four age categories, our network was designed with a clearly defined target: the score from the Beck Depression Inventory. Results: In all networks studied, psychological parameters (e.g., tension, depression, hostility, fatigue, confusion, and total mood disturbance) emerged as the most influential nodes in relation to the targeted node (Eigenvector centrality of approximately 0.30). Additionally, sleep quality was identified as the next most relevant parameter for the general network (Eigenvector = 0.25), while nutritional factors-particularly carbohydrates-demonstrated greater prestige within the male network (Eigenvector = 0.06). Nutritional parameters had a stronger influence on depressive symptoms among individuals aged 29-39 years (Eigenvectors = 0.09, 0.09, and 0.14 for energy, carbohydrates, and fat, respectively). Conclusions: This novel approach allowed for a clearer visualization of how the studied parameters impact depressive symptoms, revealing significant differences when certain aspects are examined independently across distinct groups.

The Impact of the COVID-19 Pandemic: A Longitudinal Analysis of Body Weight Variations and Their Implications for Daily Habits.

Assessing changes in lifestyle, dietary habits, eating behaviors, and stress during the pandemic and their impact on weight is crucial for developing effective interventions. This study investigated weight variations among Brazilians and associated habit changes over nine months during the COVID-19 pandemic. An online questionnaire was applied (T0/T1, T2). Weight variation classifications were determined from T0 to T1 and evaluated longitudinally for changes in lifestyle, dietary habits, food consumption, eating behavior, and perceived stress using generalized estimating equations (p < 0.05). Out of 453 participants, 23.6% lost weight, 18.1% maintained their weight, 26.0% gained up to 2.4 kg, and 32.2% gained ≥ 2.5 kg. Weight loss was associated with decreased food consumption and increased stress at T2. The group that gained up to 2.4 kg reported reduced food intake, snacking, meal preparation, and candy consumption but increased stress at T2. Those gaining ≥ 2.5 kg initially increased food consumption, snacking, meal preparation, hamburgers/canned products, sugary drinks, instant meals/snacks, candies, and fast food consumption at T1, all of which were reduced at T2, along with a decrease in uncontrolled and emotional eating. Although the pandemic initially affected daily habits differently based on weight changes, participants-especially those who gained more weight-tended to revert to pre-pandemic habits.

Meal Timing and Sleep Health Among Midlife Mexican Women During the Early Stages of the COVID-19 Pandemic.

BACKGROUND/OBJECTIVES: This study aimed to examine associations between meal timing habits and sleep health in midlife Mexican women. METHODS: Data comprised 379 midlife Mexican women who participated in a phone survey conducted within the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) project during the early stages of the COVID-19 pandemic. Women answered questions related to meal habits and sleep duration, latency, and quality. We used linear regression to investigate the associations between meal timing, frequency of meals/snacks, eating window (duration between first and last eating occasion of the day), duration between last meal, bedtime, sleep duration, and logistic regression to examine the associations between meal timing, sleep latency, and sleep quality, adjusting for confounders. RESULTS: Later timing of meals throughout the day, and a shorter interval between the last meal of the day and bedtime, were associated with prolonged sleep latency and worse sleep quality. Associations with sleep duration were mixed: a longer eating window and a later largest and last meal were each associated with shorter sleep duration, while a later first meal and a shorter interval between the last meal of the day and bedtime were associated with longer sleep duration. CONCLUSIONS: Meal timing habits are associated with sleep duration, latency, and quality in midlife women.

Evaluation of the Aral Region Adolescent Nutrition with the FFQ_KZ Questionnaire.

The rapid drop in the Aral Sea's level since the 1960s has resulted in an environmental disaster and major shifts in quality of life. The research aims to determine the eating habits of adolescents from 11 to 17 years old living in the Aral Sea Basin by using an FFQ questionnaire. The respondents' diets were found to be unbalanced due to a shortage of proteins, polyunsaturated fatty acids, and complex carbohydrates, with a predominance of easily digestible carbohydrates and plant proteins. The study highlights the need for educational efforts to increase awareness of the consequences of poor nutrition.

Docosahexaenoic Acid and Sleep Quality in Very and Extreme Preterm Infants.

The results regarding the association of plasma docosahexaenoic acid (DHA) levels with sleep duration conflict. This study aimed to investigate the effect of oral administration of DHA on the sleep quality of Brazilian extreme preterm infants. This cohort study is part of the Joinville Docosahexaenoic Acid Study (JoiDHA) conducted with 59 infants in Joinville, Brazil. Sleep quality was assessed using the Brief Infant Sleep Questionnaire, which consists of 12 questions about the quality of sleep the week prior to its application and was answered by the parents/guardians. Of the 59 children who participated in the study, 37 (62.7%) were supplemented with DHA and 22 (37.3%) did not receive DHA. The prevalence of poor sleep quality was higher among children with the weight status at birth <50th percentile (68.2%; p = 0.045) when compared to children ≥50th percentile. However, Poisson regression analysis showed that neither weight status at birth nor DHA use was associated with sleep quality, even after adjusting for the same variables. In summary, sleep quality 12-24 months after birth was not associated with DHA supplementation in very and extreme preterm infants. Additional studies that address the increase in DHA intake would be important for the understanding of the effect of this fatty acid on sleep quality.

Comparing the Dietary Habits and the Food Choices Between Italian and Dominican Adult Populations: Focus on Fruit and Vegetable Intakes and Their Association with Skin Carotenoid Levels.

The Mediterranean Diet (MD) is characterized by a high intake of fruits and vegetables (FVs), which is considered as an important contributor to the beneficial effects of the MD pattern. In this cross-sectional study, we compared the food choices, evaluated by dietary habit questionnaires, of a sample of 995 adults, including 601 and 394 participants from Southern Italy and the Dominican Republic, respectively. In addition, we focused on their FV consumption, assessed by the Mediterranean Diet Adherence Screener (MEDAS) questionnaire, and on its association with skin carotenoid levels as measured by the Veggie Meter®. We found that a significantly higher percentage of Italians had five meals/day and breakfast compared to Dominicans (five meals/day: 43 vs. 25, p < 0.05; breakfast: 89 vs. 79, p < 0.05), whereas a lower percentage of participants from Italy consumed snacks between the two meals compared to the Dominican Republic population (47 vs. 70, p < 0.005). Most of the participants from both populations had breakfast at home. However, 59.3% of Italians and 27.5% of Dominicans (p = 0.005) had breakfast between 7:00 and 9:00 a.m., whereas 5.8% and 27.5% (p = 0.001) had breakfast after 9:00 a.m., respectively. Milk/yogurt and eggs were the most consumed foods for breakfast in Italy and the Dominican Republic, respectively. Regarding the main meals, most of the Italians and Dominicans had a first course for lunch and a second course for dinner. Of note, we observed that approximately half of the Italians ate FVs in their main meals and had a higher carotenoid score than the Dominicans. Interestingly, in the multiple linear regression analysis, we found that the carotenoid score was positively associated with sex (ß = 0.078; p = 0.009), age (ß = 0.008; p = 0.001), vegetable consumption (ß = 0.12; p = 0.041) and the perception of a healthy diet (ß = 0.12; p = 0.001) in the Dominic Republic population, while the carotenoid score was directly associated with sex (ß = 54.97; p < 0.0001) and both vegetable (ß = 25.42; p = 0.0008) and fruit (ß = 38.61; p < 0.0001) consumption in the Italian sample. Our findings confirm the need to promote nutrition-based interventions to encourage FV intake, particularly in non-Mediterranean countries.

Sleep Patterns, Social Media Usage, and Dietary Habits during COVID-19 Lockdown in Mexico: A Cross-Sectional Study.

During the COVID-19 lockdown, a high prevalence of disruption in lifestyle habits was reported, especially concerning sleep habits. The present study aimed to explore the relationship between lifestyles and the COVID-19 lockdown on subjects living in Mexico. A cross-sectional survey was conducted. An online questionnaire was administered to survey participants. A clustering procedure was performed to identify groups of survey respondents with similar characteristics. There were 155 survey respondents. Most of them were women (83%) of young age. The clustering identified two distinct groups of subjects, i.e., Cluster 1 and 2. The subjects in Cluster 2 were younger, more likely to use social media, and spent much more time watching TV/surfing the internet than subjects in Cluster 1. Furthermore, the prevalence of problems with falling and staying asleep during the lockdown was higher in Cluster 2 than in Cluster 1 (14% in Cluster 2 vs. 4% in Cluster 1) even though nobody from Cluster 2 had sleep problems before the lockdown. The study showed that younger respondents were those more affected by lockdown measures.
