School health promotion and fruit and vegetable consumption in secondary schools: a repeated cross-sectional multilevel study.

BACKGROUND: Worldwide, recommendations for fruit and vegetable consumption are not met, which can cause chronic diseases. Especially adolescence is an important phase for the development of health behaviours. Therefore, in the Netherlands, the Healthy School program was established to aid schools in promoting healthy lifestyles among their students. We examined to what extent the variation between secondary schools regarding students' fruit and vegetable consumption could be explained by differences between schools regarding Healthy School certification, general school characteristics, and the school population. Additionally, we examined whether Healthy School certification was related to the outcomes, and whether the association differed for subgroups. METHODS: We performed a repeated cross-sectional multilevel study. We used data from multiple school years from the national Youth Health Monitor on secondary schools (grades 2 and 4, age ranged from approximately 12 to 18 years) of seven Public Health Services, and added data with regard to Healthy School certification, general school characteristics and school population characteristics. We included two outcomes: the number of days a student consumed fruit and vegetables per week. In total, we analysed data on 168,127 students from 256 secondary schools in the Netherlands. RESULTS: Results indicated that 2.87% of the variation in fruit consumption and 5.57% of the variation in vegetable consumption could be attributed to differences at the school-level. Characteristics related to high parental educational attainment, household income, and educational track of the students explained most of the variance between schools. Additionally, we found a small favourable association between Healthy School certification and the number of days secondary school students consumed fruit and vegetables. CONCLUSIONS: School population characteristics explained more variation between schools than Healthy School certification and general school characteristics, especially indicators of parental socioeconomic status. Nevertheless, Healthy School certification seemed to be slightly related to fruit and vegetable consumption, and might contribute to healthier dietary intake. We found small differences for some subgroups, but future research should focus on the impact in different school contexts, since we were restricted in the characteristics that could be included in this study.

Demographic, lifestyle, social, and psychological factors associated with worry-related sleep problems among school-going adolescents in Timor-Leste.

OBJECTIVE: Adolescent sleep problems are a worldwide public health issue. The present study examines factors associated with worry-related sleep problems among school-going adolescents. The country of interest is Timor-Leste, a low-income country, where studies pertaining to adolescent sleep problems are lacking. DESIGN AND MEASURES: Data were analysed from the Global School-Based Student Health Survey Timor-Leste (n = 3455). An ordered probit model was used to assess the effects of demographic, lifestyle, social, and psychological factors on different levels of worry-related sleep problems (i.e., no, mild and severe sleep problems). RESULTS: School-going adolescents were more likely to face mild or severe worry-related sleep problems if they were older, passive smokers, alcohol drinkers and moderately active. School-going adolescents who sometimes or always went hungry were more likely to experience worry-related sleep problems than those who did not. Involvement in physical fights, being bullied, and loneliness were positively associated with the probability of having modest or severe worry-related sleep problems. CONCLUSION: Age, exposure to second-hand smoke, alcohol consumption, physical activity, going hungry, physical fights, being bullied and loneliness are the important determining factors of adolescent worry-related sleep problems. Policymakers should pay special attention to these factors when formulating intervention measures.

The influence of early diet quality on the mental health of college students: the mediation effects of height and qi-deficiency.

Background: In China, the prevalence of mental health issues among college students is a significant concern in society. This study aims to investigate the impact of early dietary quality on the psychological well-being of college students and elucidate the underlying mechanisms through which these effects occur, specifically focusing on height and qi-deficiency as mediators according to Chinese traditional medicine (CTM). Methods: A total of 655 college students were surveyed in October 2023 using paper-pencil-based questionnaires at four second-tier universities in Sichuan Province. The assessment included mental health, height, and qi-deficiency. Pearson's correlation and linear regression analyses were employed to examine the mediation model and test the hypotheses. Results: The college students exhibited acceptable levels of early diet quality (M = 3.72) and mental health (M = 3.63), while also presenting mild qi-deficiency symptoms (M = 2.25). Their average height was measured at 164.61 cm. Early diet quality demonstrated significant associations with mental health (r = 0.38, p < 0.01), height (r = 0.32, p < 0.01), and qi-deficiency (r = -0.32, p < 0.01). Mental health displayed correlations with height (r = 0.32, p < 0.01) and qi-deficiency (r = -0.49, p < 0.01). The results of linear regression analyses revealed significant associations between early diet quality and mental health (ß = 0.31, p < 0.01), height (ß = 0.21, p < 0.01), as well as qi-deficiency (ß = -0.26, p < 0.01). Furthermore, when early diet quality was included in the regression model, both height (ß = 0.21, p < 0.01) and qi-deficiency (ß = -0.35, p < 0.01) emerged as significant mediators in the relationship with mental health. Conclusion: The mediation model and hypotheses were strongly supported, demonstrating that early diet quality exerted an influence on the mental health of college students through two distinct pathways: height and qi-deficiency. Moreover, the mediating effect of qi-deficiency was found to be more pronounced than that of height in the relationship between early diet quality and mental health among college students.

Does sensation-seeking behavior influence the patterns of flavored e-cigarette use? A cross-sectional study among Indonesian adolescents and young adults.

BACKGROUND: The variety of available flavors in e-cigarettes may be a driver for young people to start using these products. The objectives of our study were to examine the relationship between sensation-seeking behavior and e-cigarette use, and to identify the predictors of flavor use patterns among adolescents in Indonesia. METHODS: Students aged 15 to 24 years participated from randomly selected high schools and universities in Indonesia. Participants answered questions about their demographic data, e-cigarette use, conventional cigarette use, and sensation-seeking. Flavor preferences were identified from eight different flavor categories. Multivariate multinomial regression analysis was employed to predict conventional cigarette and e-cigarette use among students. A latent class analysis was conducted to determine the number of latent classes of flavor use. RESULTS: One thousand six hundred high school and university students, with a mean age of 18.2 years (SD 2.19), were recruited between March and August, 2023. Conventional cigarette use in the past 30 days was higher (16.3%) compared to e-cigarette use (13.3%, p = 0.017), with approximately 8.5% of students were being dual users. Higher levels of sensation-seeking significantly increased the odds of being a current e-cigarette user (OR = 2.54, 95%CI 1.99-3.25) and a current conventional cigarette smoker (OR = 2.38, 95%CI 1.85-3.07). Three groups of flavor classes were identified: 1) primarily menthol flavor users (14%), who had a strong association with current conventional cigarette use; 2) experimenters, who mostly preferred fruit-flavored e-cigarettes (76%); and 3) the multi-flavor user group (10%), who had a higher sensation-seeking tendency. CONCLUSIONS: Flavors, especially menthol and fruit flavors, attract youth, broaden the e-cigarette audience and are particularly appealing to high sensation-seekers. Banning these flavors could significantly deter e-cigarette initiation among youth.

Sleep and mental health among Chinese adolescents: the chain-mediating role of physical health perception and school adjustment.

OBJECTIVE: Sleep problems and their detrimental effects on adolescents' physical and mental health have received substantial attention. Prior studies have focused mainly on the direct association between sleep and mental health; however, little is known about the underlying mediating mechanism. To address this gap, the present study constructed a chain mediation model to examine the association between sleep deficiency and mental health status in adolescents, by introducing two mediating variables-physical health perception and school adjustment. METHODS: A sample of 7530 senior high school students completed a battery of self-report questionnaires measuring their sleep duration, mental health status, physical health perception, and school adjustment. Data were collected from the Database of Youth Health at Shandong University. All the measures showed good reliability and validity in the present study. Data were analyzed using SPSS 25.0 and the SPSS PROCESS. RESULTS: The results were as follows: (1) Sleep duration was significantly associated with physical health perception and mental health. (2) Physical health perception partially mediated the association between sleep and mental health. (3) Physical health perception and school adjustment played a chain mediating role between sleep and mental health. In conclusion, sleep not only directly associated with mental health among adolescents, but also influences mental health by the chain mediating effect of perception of physical health and school adjustment. CONCLUSION: These findings in the present study contribute to understanding the mechanisms underlying the association between sleep and mental health and have important implications for interventions aimed at improving mental health status among adolescents in China. Our results indicated that promoting adequate sleep duration and improving sleep quality are possible key mental health promotion strategies for adolescents.

The mediating effect of subject well-being between physical activity and the internet addiction of college students in China during the COVID-19 pandemic: a cross-sectional study.

Background: Internet addiction poses a significant threat to the health of college students worldwide, but physical activity, as a highly safe and effective rehabilitative measure, has shown promise for alleviating this issue nowadays. However, during the COVID-19 pandemic, the mediating processes in this association remained unclear. This study aims to explore the impact of physical activity on internet addiction among college students and the mediating role of subjective well-being. Methods: A survey was conducted on 216 eligible college students using the physical activity level scale, the internet addiction test, and the subjective well-being scale. For data analysis, independent sample t-tests, correlation analysis, hierarchical regression analysis, and mediating effect tests were in turn carried out in this work. Results: The study revealed noteworthy gender disparities in physical activity and internet addiction among college students (ß = -0.356, p < 0.01; ß = 0.140, p < 0.05). Compared to females, male students manifest elevated levels of physical activity and lower scores in internet addiction. Physical activity and subjective well-being exerted a significantly negative predictive influence on internet addiction (ß = -0.162, p < 0.05; ß = -0.508, p < 0.001). What's more, subjective well-being assumed a crucial mediating role in the relationship between physical activity and internet addiction, with the mediating effect accounting for 72.81% of the total effect. Conclusion: This study deepens the understanding of how physical activity reduces internet addiction risk while emphasizing that enhancing subjective well-being is an effective strategy for college students to cope with Internet addiction.

The effect of perceived stress on menstrual complaints in university students.

Studies have examined the effect of stress on dysmenorrhea and premenstrual syndrome. For this reason in this study, it was aimed to determine the impact of stress on menstrual symptoms (adverse effects, abdominal pain, and coping methods). This descriptive and correlational study was conducted with 351 university students in Turkey by sharing the link to the questionnaire on online social media platforms. It was determined that those whose income was equal to their expenses had lower menstrual symptoms, having a chronic disease and smoking increased menstrual symptoms (F = 3.19/p = .04; t = 2.33/p = .02; t = 3.96/p = .00). The study identified that there was a positive low-level correlation (r: 0.25, p < .01) between the Perceived Stress Scale-14 and the Menstruation Symptom Questionnaire, and the 6.5 percent change in menstrual symptoms was explained by perceived stress. In the study, it is thought that stress affects the experience of menstrual symptoms. Therefore, it is believed that by providing training on stress and effective coping methods by midwives and nurses, menstrual symptoms can be reduced, contributing to women's health. For future studies, it is recommended to examine the effects of stress coping methods training on stress and menstrual complaints.

Clusters of lifestyle behavioral risk factors and their associations with depressive symptoms and stress: evidence from students at a university in Finland.

BACKGROUND: No previous research of university students in Finland assessed lifestyle behavioral risk factors (BRFs), grouped students into clusters, appraised the relationships of the clusters with their mental well-being, whilst controlling for confounders. The current study undertook this task. METHODS: Students at the University of Turku (n = 1177, aged 22.96 ± 5.2 years) completed an online questionnaire that tapped information on sociodemographic variables (age, sex, income sufficiency, accommodation during the semester), four BRFs [problematic alcohol consumption, smoking, food consumption habits, moderate-to-vigorous physical activity (MVPA)], as well as depressive symptoms and stress. Two-step cluster analysis of the BRFs using log-likelihood distance measure categorized students into well-defined clusters. Two regression models appraised the associations between cluster membership and depressive symptoms and stress, controlling for sex, income sufficiency and accommodation during the semester. RESULTS: Slightly more than half the study participants (56.8%) had always/mostly sufficient income and 33% lived with parents/partner. Cluster analysis of BRFs identified three distinct student clusters, namely Cluster 1 (Healthy Group), Cluster 2 (Smokers), and Cluster 3 (Nonsmokers but Problematic Drinkers). Age, sex and MVPA were not different across the clusters, but Clusters 1 and 3 comprised significantly more respondents with always/mostly sufficient income and lived with their parents/partner during the semester. All members in Clusters 1 and 3 were non-smokers, while all Cluster 2 members comprised occasional/daily smokers. Problematic drinking was significantly different between clusters (Cluster 1 = 0%, Cluster 2 = 54%, Cluster 3 = 100%). Cluster 3 exhibited significantly healthier nutrition habits than both other clusters. Regression analysis showed: (1) males and those with sufficient income were significantly less likely to report depressive symptoms or stress; (2) those living with parents/partner were significantly less likely to experience depressive symptoms; (3) compared to Cluster 1, students in the two other clusters were significantly more likely to report higher depressive symptoms; and (4) only students in Cluster 2 were more likely to report higher stress. CONCLUSIONS: BRFs cluster together, however, such clustering is not a clear-cut, all-or-none phenomenon. Students with BRFs consistently exhibited higher levels of depressive symptoms and stress. Educational and motivational interventions should target at-risk individuals including those with insufficient income or living with roommates or alone.

Mental Health in Doctoral Students: Individual, Academic, and Organizational Predictors.

BACKGROUND: The mental health of doctoral students is a matter of concern, and several variables appear to be associated with the state of their mental health. However, there have been no studies on the population of doctoral students in Spain to date using validated instruments. METHOD: A cross-sectional observational study was conducted to assess mental health in 1,018 doctoral students. The impact of personal, academic, psychological, and social/organisational variables on their mental health was assessed. RESULTS: Between 50% and 60% of the sample might be experiencing a common psychological disorder, while 18.8% of the sample might be experiencing passive suicidal ideation. In addition, using binary logistic regression, significant predictors of negative mental health were identified, including: sociodemographic variables (being female); academic variables (longer time spent in a doctoral programme); psychological variables (lower life satisfaction; greater interference and less clarity about negative emotions); and social and organisational variables (greater fear of losing tuition rights, lower social support, and greater interference of academic work with personal life). CONCLUSIONS: Doctoral students need measures to remedy and prevent mental health issues based on improving self-care and emotion regulation, promoting social support at university, and reducing the pressure of losing tuition rights among final-year students.

Exploring COVID-19 Phobia among International Chinese College Students in South Korea Before Ending COVID-19 Restrictions.

BACKGROUND: College students, considered to be the driving force of society, are highly vulnerable to COVID-19. At a time when facing a new pandemic wave in 2022, China's policy was in contrast with that of Korea. We investigated the phobia levels of international Chinese college students studying in Korea. OBJECTIVE: This study aimed to investigate the relationship between the frequency of use and trust of information sources, and COVID-19 phobia (C19P) among Chinese college students studying in Korea before ending related restrictions. METHODS: This study employed a cross-sectional design, conducting an online survey among Chinese college students studying in Korea from April 8-15, 2022 (before Korea ended the limitations due to COVID-19). Data about 319 respondents were analyzed, including socio-demographics, information variables, knowledge, attitudes, practices (KAP), and C19P. Hierarchical regression analysis with different models was used to examine the relationship between information trust, KAP, and C19P. RESULTS: Results showed that students performed well in knowledge and preventive practices, had diverse sources of getting information related to COVID-19, and highly depended on the internet and news. Students who perceived a higher severity of infection showed higher levels of COVID-19 phobia. The tendency to wear masks with family/friends, avoid crowded places, and not agree with Korean government mitigation policies reported higher levels of COVID-19 phobia. CONCLUSIONS: More authority and proactive communication strategies, such as consultations or education programs, are needed for international students to alleviate their phobias and psychological stress.

Prevalence and associated factors of unhealthy diet among adolescents: cross-sectional study among Tunisian high school students.

OBJECTIVES: According to World Health Organization (WHO),Unhealthy Diet (UD)is a major risk factor for chronic diseases. That's why it is important to study the UD and its associated factors. Our study aimed to describe the dietary behavior of young high school students and determine associated factors of UD. METHODS: A cross-sectional study was carried out among students of seven high schools in center-eastern Tunisia during the academic year 2021/2022. Data collection was carried out in April2022 by questionnaires. The questions concerned the socio-demographic characteristics, food habits and physical activity. WHO defined UD as the consumption of less than five fruits and vegetables per day. Data analysis was done using SPSS software. RESULTS: A total of 740 adolescents were included. The mean age was17±1.16 years with extremes ranging from 14to19 years. Sex-ratio was 0.66. UD was found among 91.6 % of the study population. At multivariate analysis, eating cake (aOR=4.062; CI [1.685-9.795]; p=0.002),eating fried-food (aOR=3.239; CI [1.118-9.385]; p=0.03)and consuming sweets (aOR=3.263; CI [1.666-6.394]; p=0.001)were independent risk factors of UD. In the other hand, regular physical activity (aOR=0.524; CI [0.294-0.936]; p=0.029)and having breakfast regularly (aOR=0.523; CI [0.297-0.923]; p=0.025)were independent protective factors of UD. CONCLUSIONS: The findings of this study showed an alarming prevalence of UD. Therefore, it is mandatory to establish effective strategies to support healthy diets and physical activity among adolescents in order to reduce non-communicable diseases related to UD.

Sex and Racial/Ethnic Patterns of Tobacco Product Use Among Students at a U.S. University in 2021-2023.

Background: Although the prevalence of conventional tobacco product use among U.S. college students has declined, an increasing number of students use various novel tobacco products. Objectives: This study aims to examine up-to-date sex and racial/ethnic patterns of tobacco use among students at a U.S. university in 2021-2023. Methods: Data of 2,732 students at an urban university in the Southeast of the U.S. were collected in 2021-2023 as part of the National College Health Assessment of the American College Health Association. Self-reported past 3-month use of five tobacco products (cigarette, electronic vapor products, water pipe/hookah, smokeless tobacco, and cigars) was dichotomized. We conducted multinomial logistic regression analysis to examine sex (male or female) and racial/ethnic (non-Hispanic White, non-Hispanic Black, Hispanic, or non-Hispanic Other) differences in single and dual/poly (con-current use of two or more tobacco products) tobacco use compared to nonuse, adjusting for age, student status, parent education level, obese status, psychological distress level, and survey year. Results: Male students had higher odds of being dual/poly tobacco user than female students, adjusting for covariates (adjusted odds ratio [AOR] = 2.00, 95% confidence interval [CI] = 1.42, 2.82). Non-Hispanic Black students had lower odds of being single (AOR = 0.43, 95% CI = 0.26, 0.69) and dual/poly (AOR = 0.09, 95% CI = 0.02, 0.37) tobacco user compared to non-Hispanic White students, adjusting for covariates. Conclusions: Considering higher health risk of con-current use of multiple tobacco products, dual/poly tobacco use prevention strategies targeting male and non-Hispanic White students may be considered.

Adolescent Δ8-THC and Marijuana Use in the US.

Importance: Gummies, flavored vaping devices, and other cannabis products containing psychoactive hemp-derived Δ8-tetrahydrocannabinol (THC) are increasingly marketed in the US with claims of being federally legal and comparable to marijuana. National data on prevalence and correlates of Δ8-THC use and comparisons to marijuana use among adolescents in the US are lacking. Objective: To estimate the self-reported prevalence of and sociodemographic and policy factors associated with Δ8-THC and marijuana use among US adolescents in the past 12 months. Design, Setting, and Participants: This nationally representative cross-sectional analysis included a randomly selected subset of 12th-grade students in 27 US states who participated in the Monitoring the Future Study in-school survey during February to June 2023. Exposures: Self-reported sex, race, ethnicity, and parental education; census region; state-level adult-use (ie, recreational) marijuana legalization (yes vs no); and state-level Δ8-THC policies (regulated vs not regulated). Main Outcomes and Measures: The primary outcome was self-reported Δ8-THC and marijuana use in the past 12 months (any vs no use and number of occasions used). Results: In the sample of 2186 12th-grade students (mean age, 17.7 years; 1054 [48.9% weighted] were female; 232 [11.1%] were Black, 411 [23.5%] were Hispanic, 1113 [46.1%] were White, and 328 [14.2%] were multiracial), prevalence of self-reported use in the past 12 months was 11.4% (95% CI, 8.6%-14.2%) for Δ8-THC and 30.4% (95% CI, 26.5%-34.4%) for marijuana. Of those 295 participants reporting Δ8-THC use, 35.4% used it at least 10 times in the past 12 months. Prevalence of Δ8-THC use was lower in Western vs Southern census regions (5.0% vs 14.3%; risk difference [RD], -9.4% [95% CI, -15.2% to -3.5%]; adjusted risk ratio [aRR], 0.35 [95% CI, 0.16-0.77]), states in which Δ8-THC was regulated vs not regulated (5.7% vs 14.4%; RD, -8.6% [95% CI, -12.9% to -4.4%]; aRR, 0.42 [95% CI, 0.23-0.74]), and states with vs without legal adult-use marijuana (8.0% vs 14.0%; RD, -6.0% [95% CI, -10.8% to -1.2%]; aRR, 0.56 [95% CI, 0.35-0.91]). Use in the past 12 months was lower among Hispanic than White participants for Δ8-THC (7.3% vs 14.4%; RD, -7.2% [95% CI, -12.2% to -2.1%]; aRR, 0.54 [95% CI, 0.34-0.87]) and marijuana (24.5% vs 33.0%; RD, -8.5% [95% CI, -14.9% to -2.1%]; aRR, 0.74 [95% CI, 0.59-0.94]). Δ8-THC and marijuana use prevalence did not differ by sex or parental education. Conclusions and Relevance: Δ8-THC use prevalence is appreciable among US adolescents and is higher in states without marijuana legalization or existing Δ8-THC regulations. Prioritizing surveillance, policy, and public health efforts addressing adolescent Δ8-THC use may be warranted.

A large-scale study on the prevalence of math anxiety in Qatar.

BACKGROUND: Math anxiety (MA) is a worldwide appearing academic anxiety that can affect student mental health and deter students from math and science-related career choices. METHOD: Using the Arabic version of the Modified-Abbreviated Math Anxiety Scale (m-AMAS), the prevalence of MA was investigated in a very large sample of students (N = 10093) from grades 7 to 12 in Qatar. RESULTS: The results showed a better fit to the original two-factor model of the m-AMAS (learning MA and Evaluation MA) than to a single-factor solution. This two-factor model was also confirmed in each grade. Notably, the distribution of MA scores was right-skewed, especially for learning MA. Using the inter-quartiles ranges, norms for MA were provided: A score of ≤16 indicates low MA whereas a score of ≥30 identifies high MA. Previous studies conducted in Western countries defined high math-anxious students as those who score above the 90th percentile corresponding to a score of 30 on the m-AMAS. Using this cut-off criterion, the current study found that one-fifth of students in Qatar were highly math-anxious, with a higher proportion of females than males. We also calculated the percentage of participants selecting each response category for each questionnaire item. Results showed that attending a long math class was the context that elicited the highest levels of learning MA. In contrast, having an unexpected math test was the situation that triggered the highest levels of evaluation MA. CONCLUSION: The prevalence of MA might vary across different cultures.

Nomophobia and Alcohol, Tobacco, and Cannabis Consumption in Adolescents in Galicia.

This study aimed at exploring the association of nomophobia with alcohol, tobacco, and/or cannabis consumption among high school students. We carried out a cross-sectional study among high school and vocational training students in Galicia, Northwest Spain (N = 3,100). Collected data included nomophobia, sociodemographic variables, and alcohol, tobacco, and cannabis consumption. Nomophobia was measured using the validated Nomophobia Questionnaire. Adjusted odds ratios (ORs) and their 95 percent confidence intervals (CIs) were estimated using generalized linear mixed models. More than a quarter of the adolescents (27.7 percent) had nomophobia. We found an association between nomophobia and a high level of tobacco smoking in the last month in boys (OR = 2.16; 95 percent CI: 1.55-3.03). Nomophobia was also associated with higher odds of binge drinking in both genders (girls: OR = 1.86; 95 percent CI: 1.61-3.52; boys: OR = 2.29; 95 percent CI: 1.68-3.13) and with cannabis consumption in boys (OR = 1.74; 95 percent CI: 1.07-2.81). Our findings highlight the importance of a comprehensive investigation of the factors underlying alcohol, tobacco, and cannabis consumption in the adolescent population.

How Do Gain-Loss Frames and Cultural Arguments Persuade? Designing Effective Messages to Weaken College Students' Binge-Drinking Intentions.

To design effective health messages, this study investigates the effects of gain-loss framing and relevant moderating effects in the context of college students' alcohol use. Specifically, based on an online experiment, we tested the moderation effects of message-sidedness and binge-drinking behaviors using a mediation model in which the association between gain-loss framing and behavioral intentions is mediated by attitudes toward binge-drinking. Four hundred thirty-four Korean college students participated in this study. Hayes' PROCESS Macro for SPSS was employed for the analysis. The results show that loss-framing significantly increased participants' unfavorable attitudes toward binge-drinking in the one-sided message condition. Moreover, attitudes toward binge-drinking were more significantly associated with behavioral intentions to binge-drink among heavy drinkers than among non-heavy drinkers. Our findings suggest important theoretical and practical implications for the development of message-framing strategies in health campaigns designed to prevent college students' binge-drinking in collectivistic societies where the cultural meaning of drinking extends beyond the individual realm to the larger social context.

Temporal trends of carbonated soft-drink consumption among adolescents aged 12-15 years from eighteen countries in Africa, Asia and the Americas.

Carbonated soft-drink consumption is detrimental to multiple facets of adolescent health. However, little is known about temporal trends in carbonated soft-drink consumption among adolescents, particularly in non-Western countries. Therefore, we aimed to examine this trend in representative samples of school-going adolescents from eighteen countries in Africa, Asia and the Americas. Cross-sectional data from the Global School-based Student Health Survey 2009-2017 were analysed. Carbonated soft-drink consumption referred to drinking carbonated soft-drinks at least once per day in the past 30 d. The prevalence of carbonated soft-drink consumption was calculated for each survey, and crude linear trends were assessed by linear regression models. Data on 74 055 students aged 12-15 years were analysed (mean age 13·9 (sd 1·0) years; 49·2 % boys). The overall mean prevalence of carbonated soft-drink consumption was 42·1 %. Of the eighteen countries included in the study, significant decreasing, increasing and stable trends of carbonated soft-drink consumption were observed in seven, two and nine countries, respectively. The most drastic decrease was observed in Kuwait between 2011 (74·4 %) and 2015 (51·7 %). Even in countries with significant decreasing trends, the decrease was rather modest, while some countries with stable trends had very high prevalence across time (e.g. Suriname 80·5 % in 2009 and 79·4 % in 2016). The prevalence of carbonated soft-drink consumption was high in all countries included in the present analysis, despite decreasing trends being observed in some. Public health initiatives to reduce the consumption of carbonated soft-drink consumption among adolescents are urgently required.

Introduction: University students, due to time constraint sand overloaded academic tasks, have unhealthy Lifestyles(LE). It is necessary to know the characteristics of this problem to identify educational intervention strategies and more effective practices that improve the diet and nutrition of university student. Objective: The objective of the study is to determine the relationship between lifestyles and body mass index in university students from the altiplanic zone (3812 masl) in Peru. Material and methods: Study with a quantitative ap-proach, descriptive, correlational and cross-sectional. The pop-ulation was constituted by the students of the NationalUniversity of the Altiplano, a sample of 194 students was con-sidered. A survey was applied using a self-administered ques-tionnaire as an instrument to collect information on sociode-mographic characteristics and EV. To assess the nutritionalstatus, weight and height were taken with which the Body MassIndex (BMI) was estimated. The data analysis was carried outusing the SPSS version 22 program, applying the estimation ofdescriptive statistics, t student, ANOVA and the Chi-square test.Results: The average BMI of university students indicatesthat their nutritional status is in the normal range, with 22.57and 23.32 Kg/m2 for men and women respectively, with nostatistical difference. According to the BMI, 3.1% have a nu-tritional deficit, 76.3% have a normal nutritional status, and20.6% are overweight and obese. The average of: weight is64.06 Kg in men and 55.59 Kg in women and height is 1.68m in men and 1.54 m in women. The average weight andheight according to sex is statistically different.Conclusions: One in five students is overweight andobese. The EV indicators that are related to BMI are: Bodyperception (p=0.003), alcohol consumption (p=0.011), andquality sleep (p=0.027). The other EV indicators do not havea significant relationship with the BMI (AU)

Factores asociados a la ingesta dietética en universitarios peruanos en tiempos de post pandemia / Factors associated with dietary intake in Peruvian university students in post-pandemic times

Introducción: La ingesta dietética de los universitarios peruanos pueden verse afectados por diferentes factores que determinan una condición de salud física y mental lo cual frus trael desarrollo académico óptimo. Objetivo: Identificar los factores asociados a la ingesta dietética en universitarios del Perú, en tiempos de postpandemia. Material y métodos: El estudio fue de corte transversal, participaron 393 universitarios peruanos, mediante una encuesta de ingesta dietética con 8 grupos de alimentos (tubérculos y raíces, cereales y derivados, menestras, carnes y de-rivados, alimentos ultraprocesados, aceites vegetales, verduras, frutas), 7 factores (convive con la familia, lugar deconsumo de alimentos, consumo de alcohol, consumo de tabaco, cambios económicos en el hogar, horas de sueño, actividad física) y tres categorías (disminuyó, sin cambios, incre-mentó). El análisis bivariado se realizó entre los grupos de alimentos y los factores asociados a la ingesta dietética y seempleó la prueba de Chi-cuadrado. Resultados: Los alimentos tuvieron una asociación directacon ingesta de cereales y tubérculos con la convivencia fami-liar (p=0.037; p=0.01 respectivamente), las menestras conlugar de consumo de alimentos (p=0.002) y convivencia fa-miliar (p=0.001), la ingesta de carnes con lugar de consumode alimentos (p= 0.006), consumo de alcohol (p= 0.028) y cambios económicos en el hogar (p=0.033). La ingesta defrutas con la actividad física (p=0.021), la ingesta de verdu-ras con la convivencia familiar (p= 0.003), lugar de consumode alimentos (p= 0.001), consumo de alcohol (p=0.049) yhoras de sueño (p=0.036). La ingesta de aceites vegetalescon la convivencia familiar (p=0.02) y los alimentos ultrapro-cesados con el lugar de consumo (p=0.002) y consumo de al-cohol (p=0.044) (AU)

Introduction: The dietary intake of Peruvian universitys tudents may be affected by different factors that determine a physical and mental health condition which frustrates optimal academic development. Objective: To identify the factors associated with dietary intake in Peruvian university students in post-pandemic. Material and methods: The study was cross-sectional, 393 Peruvian university students participated in a dietary intake survey with 8 food groups (tubers and roots, cereals andderivatives, vegetables, menestras, meats and derivatives, ul-tra-processed foods, vegetable oils, vegetables, fruits), 7 fac-tors (living with the family, place of food consumption, alco-hol consumption, tobacco consumption, economic changes inthe home, hours of sleep, physical activity) and three categories (decreased, unchanged, increased). Bivariate analysiswas performed between food groups and factors associated with dietary intake and the Chi-square test was used. Results: Food had a direct association with cereal and tuber intake with family coexistence (p=0.037; p=0.01 respectively), menestras with place of food consumption (p=0.002)and family coexistence (p=0.001), meat intake with place offood consumption (p= 0.006), alcohol consumption (p=0.028) and economic changes in the household (p=0.033).Fruit intake with physical activity (p=0.021), vegetable intake with family coexistence (p= 0.003), place of food consump-tion (p= 0.001), alcohol consumption (p=0.049) and hours ofsleep (p=0.036). Vegetable oil intake with family cohabitation(p=0.02) and ultra-processed food with place of consumption(p=0.002) and alcohol consumption (p=0.044).Conclusions: The food intake of Peruvian university stu-dents was directly associated with family coexistence, place offood consumption, alcohol consumption, economic changes inthe home, physical activity and hours of sleep (AU)mes.

Meta-analysis and time trend prediction of the prevalence of hypertension in Chinese college students.

BACKGROUND: To understand the prevalence of hypertension among Chinese college students over the past decade (2010-2020) and predict its future trend, we aim to provide a basis for preventing and controlling hypertension among college students. METHODS: Databases such as Chinese National Knowledge Infrastructure, Wanfang database, PubMed, and Web of Science were searched, and publications on the prevalence of hypertension among Chinese college students from 2010 to 2020 were collected. Search for publications in both Chinese and English databases using keywords "hypertension," "prevalence," "disease status," "cross-sectional survey," "epidemiology," "China," "adolescents," and "college students." Publication screening, data extraction, and quality assessment were independently conducted by 2 researchers. Meta-analysis was performed using Stata 16, and trends in the prevalence of hypertension among college students were analyzed using R 4.2.0. RESULTS: A total of 37 publications were included in this analysis, which involved 233,603 Chinese college students. The Meta-analysis results showed significant heterogeneity among the studies (I2 = 98.9%, P < .05). Using a random-effects model, the overall prevalence of hypertension among college students was estimated to be 3.3% (95% CI = 2.9%-3.6%), with a higher prevalence among male students (6.2%, 95% CI = 5.4%-7.1%) than female students (1.1%, 95% CI = 0.9%-1.3%). The prevalence of hypertension is notably higher in northern regions than in southern regions. The prevalence of hypertension among college students showed an increasing trend from 2010 to 2020. Trend analysis predicted that the prevalence of hypertension among college students will reach 10% and 14.6% by 2030 and 2040, respectively. The risk of hypertension in male students was 4.63 times higher than that of female students (95% CI = 2.97-7.23). Compared normal weight students, overweight and obese students had 3.08 times (95% CI = 2.48-3.82) and 6.69 times (95% CI = 2.25-19.90) higher risk of hypertension, respectively. CONCLUSION: The prevalence of hypertension in Chinese college students was about 3.3%. The prevalence of hypertension in male college students was higher than that in females, and the prevalence in northern regions was generally higher than that in southern regions. The prevalence of hypertension among Chinese college students will reach 10.0% in the next 10 years and 14.6% in the next 20 years. Male and BMI ≥ 24 were risk factors for hypertension among college students.
