Children growing up are at risks of exposure to different behaviors and common social influences which if unchecked result in unexpected health consequences common among youth in America today. According to US Centers for Disease Control & Prevention, the six leading behaviors that cause death, disability, and social problems among American children are: unintentional injuries and violence, alcohol and drug use, tobacco use, unhealthy diets, inadequate physical activities, and sexual behaviors and diseases. This article shows that school health program: 1) can provide the foundation for children to learn desired healthy behaviors in order to preserve life, 2) protects the future of children and that of the nation, 3) can teach students skills to recognize risky behaviors and resist them, 4) can boost community efforts to achieve desired health behaviors, 5) closes socio-economic gaps that interfere with basic nurturing of children, and 6) finally links local stakeholders as partners in promoting community safety. Through review of literature, the authors found that it costs ($588) daily or (214,620) annually to incarcerate a juvenile and only $75 daily for the cost of individualized community-based services. The cost to New York is over $900,000, yet does not address the causative issues. The authors recommend that schools teach comprehensive school health from kindergarten to grade 12 and employ health educators to support teachers teach health promotion and education.展开更多

Methods: We have taken nearly 50 variables into consideration: 17 variables for construction of the socioeconomic status, 9 variables for the investigation of symptoms, 11 concerning drugs, 5 for healthy habits, 3 for investigating the violence behavior, 4 concerning the school, 3 for subjective health and finally 3 for social network. We have used the principal component analysis, the multiple correspondence analysis and the weighted-frequency score for reducing the number of them. After these reductions, 15 variables were available for analyses. The relationship between injuries and investigated factors was assessed using the Pearson’s chi-square test. We also calculated odds ratio (OR) with their 95% confidence intervals (95%CI) to estimate the strengths of the associations. To further assess these relationships but also for taking into account the potentials confounding effects of some variables, logistic regression model and multinomial logistic regression model were applied. Results: The whole injury prevalence was equal to 45.6% and among the injured, the proportion of the several types was equal to 33.8% for sport injuries, 32.2% for home injuries, 16.6% for traffic injuries, 11.6% for school injuries and 5.7% for work injuries. We can say that, in light of the variables studied, the “at risk” profile for having reported an injury is being a boy, being younger, having drug experiences, with the violent profile, and declaring several symptoms. There are no consistent and marked deviations in this study from the findings obtained in previous studies. Conclusion: Analyzing injuries in general is interesting but for preventing them it is important to know in which activities children and students are engaged when they are injured.展开更多

Association has been postulated between marital satisfaction, job satisfaction and mental health. There is, however, a paucity of research on marital satisfaction in Nigeria, particularly in relation to job satisfaction and psychological health. Objective: The objective of this study is thus to assess the level of marital satisfaction and to explore the relationship if any between marital satisfaction, job satisfaction and mental health of secondary school teachers in Benin City, Edo State, Nigeria. Methods: A cross sectional study was conducted on teachers in secondary schools in Benin City, Nigeria. A total population of 300 teachers who had been married and teaching for at least one year were included in the study. The information required for the study were collected using a self-administered questionnaire and two standard instruments, the Index of Marital Satisfaction (IMS) and the General Health Questionnaire 28 (GHQ 28). The GHQ was used to assess the workers psychological health, while the IMS was used to assess the degree of marital satisfaction. Results: Two hundred and fifteen (82.7%) teachers had marital satisfaction, 54 (20.8%) had psychological disorder while 56 (21.5%) were dissatisfied with their job. A strong association was found between marital dissatisfaction and psychological disorder (X2 = 56.826;df = 1, P = 0.0004). No association was found between marital dissatisfaction and job dissatisfaction. No association was also found between job dissatisfaction and psychological disorder. Conclusion: A high level of marital satisfaction was found in the study population. However, the strong association also found between marital dissatisfaction and psychological disorder provides empirical evidence on the need to educate married couples as well as the general public on the mental health implication of marital dissatisfaction.展开更多

Preschool children and their families with regular activities at public schools were invited to paticipate in the study. The following characteristics were assessed: Socio-demographic condictions, clinical health, anthropometric, biochemical, lifestyle and data on food consumption. The 56 healthy children were divided into two groups, overweight(C1) and non-overweight(C2), as well as their mothers, respectively, in overweight(M1) and non-overweight(M2). Nutritional status was defined according to results obtained through the Anthro? Software for nutritional analysis. RESULTS Thirty-five children were male, with mean age of 4.44 ± 1.0 years old. Eighty-nine percent of them were eutrophic, 86.7% were sedentary and they had five meals a day. Body mass index(BMI) for age and total cholesterol(TC) was higher on C1(P = 0.0001) and high density lipoprotein cholesterol(HDL-c) was higher on C2. Mothers were 32.5 ± 7.1 years old, mostly married and employed. Eighty-six percent of them were sedentary and 62.5% were overweight with BMI = 26.38 ± 5.07 kg/m2. Eighteen percent of the overweight mothers had isolated total hypercholesterolemia(TC levels elevated) and 12.5% had low HDL-c levels. The present study showed an association between overweight and obesity during the preschool years and the correspondent mothers' nutritional status of overweight and obesity(OR = 4.96; 95%CI: 0.558-44.17). There was a positive correlation between the food risk associated with CVD by children and mothers when their consumption was 4 times/wk(P = 0.049; r = 0.516) or daily(P = 0.000008; r = 0.892).CONCLUSION Analyzed children showed high rates of physical inactivity, high serum cholesterol levels and high consumption of food associated with risk for CVD and renal disease. Changes in habits should be encouraged early in kindergarten.展开更多

Biological samples, including morning urine and venous blood, were collected to measure concentrations of 29 typical organic pollutants, including hydroxy polycyclic aromatic hydrocarbons(OH-PAHs), bisphenol A and its substitutes, phthalates and their metabolites, parabens,and five biomarkers of oxidative stress. Health assessments included blood pressure measurements and lung function indicators.Results Urinary concentrations of 2-hydroxyphenanthrene(2-OH-PHE)(β = 4.35% [95% confidence interval(CI): 0.85%, 7.97%]), 3-hydroxyphenanthrene(β = 3.44% [95% CI: 0.19%, 6.79%]), and 4-hydroxyphenanthrene(4-OH-PHE)(β = 5.78% [95% CI: 1.27%, 10.5%]) were significantly and positively associated with systolic blood pressure. Exposures to 1-hydroxypyrene(1-OH-PYR)(β = 3.05% [95% CI:-4.66%,-1.41%]), 2-OH-PHE(β = 2.68% [95% CI:-4%,-1.34%]), and 4-OH-PHE(β = 3% [95% CI:-4.68%,-1.29%]) were negatively associated with the ratio of forced expiratory volume in the first second to forced vital capacity. These findings highlight the adverse effects of exposure to multiple pollutants on cardiopulmonary health. Biomarkers of oxidative stress, including 8-hydroxy-2'-deoxyguanosine and extracellular superoxide dismutase, mediated the effects of multiple OH-PAHs on blood pressure and lung function.Conclusion Exposure to multiple organic pollutants can adversely affect cardiopulmonary health.Oxidative stress is a key mediator of the effects of OH-PAHs on blood pressure and lung function.展开更多

文摘Background The association between substance use including marijuana use and attempted suicide has been well documented.However,little is known about marijuana use and its association with attempted suicide repetition among young people in low-income and middle-income contexts.Aims This analysis was conducted to assess the factors associated with marijuana use and ascertain marijuana use as a determinant of repeated attempted suicide among senior high school(SHS)students in Ghana.Methods Data from the 2012 Global School-Based Student Health Survey in Ghana was used for this study.Modified Poisson,Logistic and Probit models weighted with Mahalanobis distance matching within propensity calliper were employed separately to determine the hypothetical association between marijuana use and repeated attempted suicide.All analysis was performed using Stata 16 and p<0.05 was deemed statistically significant.Results The prevalence estimates of marijuana use and repeated attempted suicide among SHS students in Ghana were 3.4%(95%Cl:2.3 to 5.1)and 11.5%(95%Cl:9.1 to 14.4),respectively.The prevalence of marijuana use was significantly associated with school grade,smoking exposure,parent smoker,alcohol intake and truancy.Marijuana use was positively associated with repeated attempted suicide among SHS in Ghana correlation=0.23,p<0.001.Repeated attempted suicide among students who use marijuana was approximately threefold and fivefold significant compared with nonmarijuana use students,based on the Poisson(adjusted prevalence ratio:3.02;95%Cl:1.67 to 5.43,p<0.001)and Logistic(adjusted OR:5.06;95%Cl:3.19 to 11.64,p<0.001)estimates respectively.Also,the Probit model showed that marijuana use significantly increased the log count of repeated attempted suicide by 95%(ap:0.95;95%CI:0.49 to 1.41,p<0.001).Conclusion Marijuana use does not only influence the onset of suicidal attempts but also repeated attempted suicide among SHS students in Ghana.Special attention is required for suicide attempters with a history of repeated attempts and current marijuana use among SHS students in Ghana.Early identification of the potential risk and protective factors is recommended to inform school-based interventions.National level structured school-based substance abuse interventions and health promotion programmes would be useful.
文摘AIM To investigate the prevalence of nutritional parameters of risk for cardiovascular disease(CVD) and kidney diseases in healthy preschool children.METHODS This is an observational cross-sectional study with 60 healthy children, of both genders, aged two to six years old and 56 mothers, in Belo Horizonte, Minas Gerais, Brazil. Preschool children and their families with regular activities at public schools were invited to paticipate in the study. The following characteristics were assessed: Socio-demographic condictions, clinical health, anthropometric, biochemical, lifestyle and data on food consumption. The 56 healthy children were divided into two groups, overweight(C1) and non-overweight(C2), as well as their mothers, respectively, in overweight(M1) and non-overweight(M2). Nutritional status was defined according to results obtained through the Anthro? Software for nutritional analysis. RESULTS Thirty-five children were male, with mean age of 4.44 ± 1.0 years old. Eighty-nine percent of them were eutrophic, 86.7% were sedentary and they had five meals a day. Body mass index(BMI) for age and total cholesterol(TC) was higher on C1(P = 0.0001) and high density lipoprotein cholesterol(HDL-c) was higher on C2. Mothers were 32.5 ± 7.1 years old, mostly married and employed. Eighty-six percent of them were sedentary and 62.5% were overweight with BMI = 26.38 ± 5.07 kg/m2. Eighteen percent of the overweight mothers had isolated total hypercholesterolemia(TC levels elevated) and 12.5% had low HDL-c levels. The present study showed an association between overweight and obesity during the preschool years and the correspondent mothers' nutritional status of overweight and obesity(OR = 4.96; 95%CI: 0.558-44.17). There was a positive correlation between the food risk associated with CVD by children and mothers when their consumption was 4 times/wk(P = 0.049; r = 0.516) or daily(P = 0.000008; r = 0.892).CONCLUSION Analyzed children showed high rates of physical inactivity, high serum cholesterol levels and high consumption of food associated with risk for CVD and renal disease. Changes in habits should be encouraged early in kindergarten.
文摘Sleep disorders are highly prevalent among college students,adversely affecting their physical health,psychological well-being,and academic outcomes.While pharmacotherapy remains a common intervention,its potential for dependency and adverse effects underscores the need for safer alternatives.Physical activity,characterized by accessibility and a favorable cost-effectiveness profile,has gained attention as a non-pharmacological intervention.However,the evidence regarding its efficacy and underlying mechanisms remains inadequately synthesized.This review evaluates the role of exercise in managing sleep disorders,highlighting evidence that aerobic,resistance,and mind-body exercises improve sleep quality,particularly through moderate-to-high-intensity sessions(40-60 minutes,3 times per week),while emphasizing avoidance of exercise within 90 minutes of bedtime to prevent disruption.Long-term regular exercise typically yields better results.Mechanistically,exercise modulates sleep through circadian rhythm synchronization,psychological adjustment,anti-inflammatory actions,thermoregulation and neuroendocrine regulation.Despite promising evidence,methodological limitations persist,including heterogeneous outcome measures,short intervention durations,and restricted sample diversity.Future research should prioritize large-scale longitudinal investigations in randomized controlled trials that utilize standardized exercise protocols and objective sleep measurements.Collectively,exercise constitutes a multifactorial intervention for sleep disorder mitigation,offering personalized regimens that enhance both sleep parameters and overall quality of life.
文摘The“Double First-Class”construction focuses on the development of disciplinary connotations and the improvement of talent cultivation quality,posing higher demands on the teaching mode and talent supply of public health and preventive medicine disciplines.Environmental health,as a core course in public health and preventive medicine,directly relates to the cultivation of effective composite public health talents.Based on the core orientation of the“Double First-Class”construction and combining the talent cultivation and course characteristics of environmental health,this paper explores the significance of teaching reform and talent cultivation in environmental health from the perspective of“Double First-Class”construction.It also investigates the paths for teaching reform and talent cultivation from multiple dimensions,aiming to provide references for cultivating high-quality professionals who meet the needs of national public health development and ecological environmental protection.
文摘Insomnia,anxiety,and depression have emerged as significant public mental health concerns,particularly during the coronavirus disease 2019(COVID-19)pandemic.Early recognition and intervention,addressing COVID-19's health effects before diverse symptoms appear,will expedite recovery and significantly enhance public mental health.Li et al conducted a cross-sectional online survey to assess neuroticism,cognitive function,insomnia,and emotional disorders in adult participants,examining how these factors correlate with mental health.The study revealed that a substantial number of participants reported experiencing varying degrees of anxiety,depression,and insomnia,most of which were classified as mild.Neuroticism was found closely associated with cognitive failure and poor mental health.Furthermore,moderated mediation analysis indicated that cognitive failure mediated the relationship between insomnia and anxiety and depression,whereas neuroticism moderated the pathway.These findings suggest that improving the subjective cognitive function and emotional stability can significantly improve mental health.However,this study has several limitations,including a limited sample size,cross-sectional design,and a focus on behavioral-level data.Future research should broaden its scope to include multiple hospitals at various levels to enhance the representativeness of the study population,adopt longitudinal designs,and integrate advanced technologies such as neuroimaging to explore the neural mechanisms underlying these conditions.
文摘This comprehensive review synthesizes findings from the studies conducted for more than two decades to assess en-vironmental and human health impacts near Spain's first hazardous waste incinerator(HWI)located in Constantí(Tarra-gona,Catalonia).Through integrated analysis of polychlorinated dibenzo-p-dioxins/furans(PCDD/Fs)and metals across soil,vegetation,human tissues,and dietary matrices,the studies have shown:(1)PCDD/F concentrations decreased 75-96%in biological samples and dietary intake over 20 years,aligning with global emission reductions rather than HWI-4 operations;(2)metal trajectories showed arsenic intermittently exceeding carcinogenic thresholds in soils(1.1×10^(-4) risk index)and chromium accumulating in autopsy tissues(+16% in kidney),although without HWI-specific spatial gradi-ents;(3)systemic biomarkers revealed policy-driven declines—blood lead dropped 70% post-EU regulations,while mer-cury became undetectable in tissues post-2010.Health risk assessments confirmed that PCDD/F intake(0.122 pg WHO-TEQ/kg/day)remained still below WHO thresholds,with no attributable cancer risks for metals except legacy arsenic.The studies included in the program of surveillance show that PCDD/Fs and metals emissions by the HWI have meant a rather low contribution to population exposure to metals and PCDD/Fs compared to dietary and historical sources.How-ever,residual risks warrant attention.It mainly concerns chromium speciation and arsenic in soils,as well as the effects on vulnerable subpopulations and the synergistic effects among toxicants.Epidemiological studies are also required.

文摘There have been reports of potential health risks for people from hydrophobic organic pollutants,such as polycyclic aromatic hydrocarbons(PAHs),polychlorinated hydrocarbons(PCHs),and organophosphate flame retardants(OPFRs).When a contaminated site is used for residential housing or public utility and recreation areas,the soil-bound organic pollutantsmight pose a threat to human health.In this study,we investigated the contamination profiles and potential risks to human health of 15 PAHs,6 PCHs,and 12 OPFRs in soils from four contaminated sites in China.We used an in vitro method to determine the oral bioaccessibility of soil pollutants.Total PAHswere found at concentrations ranging from26.4 ng/g to 987 ng/g.PCHs(0.27-14.3 ng/g)and OPFRs(6.30-310 ng/g)were detected,but at low levels compared to earlier reports.The levels of PAHs,PCHs,and OPFRs released from contaminated soils into simulated gastrointestinal fluids ranged from 1.74%to 91.0%,2.51%to 39.6%,and 1.37%to 96.9%,respectively.Based on both spiked and unspiked samples,we found that the oral bioaccessibility of pollutantswas correlated with their logKow andmolecularweight,and the total organic carbon content and pH of soils.PAHs in 13 out of 38 contaminated soil samples posed potential high risks to children.When considering oral bioaccessibility,nine soils still posed potential risks,while the risks in the remaining soils became negligible.The contribution of this paper is that it corrects the health risk of soil-bound organic pollutants by detecting bioaccessibility in actual soils from different contaminated sites.
文摘Purpose:This study aims to foster a dialog between the experiences and identities of Nigerian female breast cancer survivors and Margaret Newman’s theory of health as expanding consciousness.The theory was employed to explore and describe the structure and meaning of these survivors’experiences and identities.Methods:Twenty-two participants were interviewed using a qualitative approach.The interviews were digitally recorded and transcribed verbatim.Data analysis was conducted using NVivo 14 software to identify recurring patterns within the data.Results:Three core themes emerged:(1)Encountering Selfhood-Otherhood in the survivorship journey,(2)navigating the rhythms of change,and(3)living the paradox of order and disorder.These themes reflect the unique and paradoxical rhythm of life as a breast cancer survivor,integrating these experiences conceptually.Conclusions:This study illuminates how Nigerian breast cancer survivors construct the patterns of meaning of their experiences by shifting the focus from solely evidence-based interventions to a deeper exploration of lived experience,cultural narratives,and expanding consciousness.Through compassionate and insightful nursing interactions,women can explore their evolving identities,foster resilience,and redefine their lives in meaningful and fulfilling ways within their unique contexts.Implications for Cancer Survivors:Greater attention is required to address the emotional,temporal,and economic dimensions of breast cancer survivorship in Nigeria.Nurses play a crucial role in helping survivors find meaning in their experiences,recognizing that order and disorder in life are integral to expanding consciousness.Survivors should be empowered to identify their patterns of living and leverage their strengths in navigating the survivorship journey and finding meaning in their lives.

文摘Objective The study aim was to investigate the effects of exposure to multiple environmental organic pollutants on cardiopulmonary health with a focus on the potential mediating role of oxidative stress.Methods A repeated-measures randomized crossover study involving healthy college students in Beijing was conducted. Biological samples, including morning urine and venous blood, were collected to measure concentrations of 29 typical organic pollutants, including hydroxy polycyclic aromatic hydrocarbons(OH-PAHs), bisphenol A and its substitutes, phthalates and their metabolites, parabens,and five biomarkers of oxidative stress. Health assessments included blood pressure measurements and lung function indicators.Results Urinary concentrations of 2-hydroxyphenanthrene(2-OH-PHE)(β = 4.35% [95% confidence interval(CI): 0.85%, 7.97%]), 3-hydroxyphenanthrene(β = 3.44% [95% CI: 0.19%, 6.79%]), and 4-hydroxyphenanthrene(4-OH-PHE)(β = 5.78% [95% CI: 1.27%, 10.5%]) were significantly and positively associated with systolic blood pressure. Exposures to 1-hydroxypyrene(1-OH-PYR)(β = 3.05% [95% CI:-4.66%,-1.41%]), 2-OH-PHE(β = 2.68% [95% CI:-4%,-1.34%]), and 4-OH-PHE(β = 3% [95% CI:-4.68%,-1.29%]) were negatively associated with the ratio of forced expiratory volume in the first second to forced vital capacity. These findings highlight the adverse effects of exposure to multiple pollutants on cardiopulmonary health. Biomarkers of oxidative stress, including 8-hydroxy-2'-deoxyguanosine and extracellular superoxide dismutase, mediated the effects of multiple OH-PAHs on blood pressure and lung function.Conclusion Exposure to multiple organic pollutants can adversely affect cardiopulmonary health.Oxidative stress is a key mediator of the effects of OH-PAHs on blood pressure and lung function.
文摘目的使用河北省营养项目人群数据,探讨母亲孕期空气颗粒物(PM)暴露对新生儿体格发育状况指标的影响,并评估不同颗粒物暴露的滞后效应以确定敏感时间窗。方法本研究基于河北孕期营养干预项目数据,纳入14148对母婴数据,通过China High Air Pollutants(CHAP)数据库获取1 km×1 km分辨率的月均PM浓度,结合孕妇居住地址和孕周估算孕早期、孕中期、孕晚期及全孕期的PM暴露水平。新生儿体格发育状况指标根据中国标准按照不同孕周和性别标准化为Z评分。采用多元线性回归模型分析不同PM暴露与新生儿体格发育状况指标的关联,并通过分布滞后线性模型评估不同妊娠阶段的滞后效应,明确敏感时间窗。结果全孕期每增加10μg/m 3的PM 2.5、PM 10和PM_(2.5-10)暴露分别使出生体重Z评分下降0.03(95%CI:-0.04,-0.02)、0.03(95%CI:-0.04,-0.02)和0.10(95%CI:-0.12,-0.08);出生身长和头围Z评分亦呈负相关,且PM_(2.5-10)的影响最显著。分布滞后线性模型结果显示,孕早期和孕晚期为新生儿出生体重和身长的关键敏感窗口,出生头围的敏感期主要集中在孕早期。结论孕期PM暴露与新生儿体格发育状况呈显著负相关,PM_(2.5-10)的效应最为突出。孕早期和孕晚期暴露为胎儿体格发育影响的关键窗口期。本研究为空气污染防控政策及孕期健康干预提供了重要的科学依据。
