Socioeconomic status and social mobility that occurred in our country in recent decades have contributed to a new reality from the point of view of health care. There have been a possibility of improve in risk factors due to epidemiological transition as occurred in developed countries where there were improvements in them. Thus it aimed to assess how the behavior of these risk factors in a cohort started at birth in 1978/79 and reviewed in 2002/04 in the state Ribeirão Preto to 23/24 years of age for a total of 2069 individuals. Socio-demographic characteristics were used, and cardiovascular risk factors including diabetes, insulin resistance, obesity, metabolic syndrome, lipid profile, blood pressure, physical activity, alcohol use and smoking. There was the income classification relating the minimum wage at birth and in early adulthood. Logistic regression models were used. The results were improvement in obesity, HDLCholesterol, physical activity, insulin resistance in high-income women and physical activity and HDL-Cholesterol in high-income men; there was worse of alcohol consumption in both groups. We concluded that high-income adults especially women presented cardiovascular risk factors profiles similar to those in high-income countries. / Os fatores de risco cardiovascular contribuem para o aumento da morbidade e mortalidade e devem ser prevenidos. A situação socioeconômica e a mobilidade social ocorrida no nosso país nas últimas décadas contribuíram para uma nova realidade sob o ponto de vista de cuidados de saúde. Há possibilidade de ter iniciado alterações nos fatores de risco com a chamada transição nutricional como a ocorrida nos países desenvolvidos nos quais houve melhoras nos mesmos. Dessa forma objetivou-se avaliar qual o comportamento desses fatores de risco em uma coorte iniciada ao nascimento em 1978/79 e reavaliada em 2002/04 na cidade paulista de Ribeirão Preto aos 23/24 anos de idade num total de 2069 indivíduos. Foram utilizadas as características sócio-demográficas, e fatores de risco cardiovasculares incluindo diabetes, resistência insulínica, obesidade, lipidograma, hipertensão arterial, atividade física, uso de álcool e hábito de fumar. Houve a classificação da renda relacionando ao salário mínimo no nascimento e na idade adulta jovem. Modelos de regressão logística foram utilizados. Os resultados evidenciaram melhorias na obesidade, atividade física, resistência insulínica, HDL-Colesterol, síndrome metabólica nas mulheres de maior renda. Nos homens de maior renda houve melhorias no HDL-Colesterol e atividade física; houve piora no consumo de álcool em ambos. Concluímos que os indivíduos pertencentes à classe com maior renda em especial as mulheres apresentaram perfis de fatores de risco cardiovascular semelhantes aos países com maior renda.

Cerebrovascular disease (CVD) can result in cerebral small vessel disease (cSVD) and structural brain changes such as decreased cortical volume, brain atrophy and cerebral infarcts which are major causes of stroke and dementia. CVD is also associated with increased depression and depressive symptoms in later life. Midlife vascular disease and adult socioeconomic status (SES) are well established risk factors but less is known about the effect of factors from earlier in life on CVD and depressive symptoms in later life. A series of systematic reviews of current literature examining early life factors and stroke, cSVD and depression following stroke are presented at the beginning of this thesis. These reviews found that childhood IQ, education and childhood SES were associated with stroke and cSVD in later life. The reviews also found that education level was associated with depression following stroke. However few of the studies adjusted for vascular risk factors and adult SES. Therefore this thesis aimed to investigate associations between birth and childhood factors and cerebrovascular disease and depressive symptoms, after adjustment for vascular risk factors and adult SES, in four community dwelling cohorts: the Stratifying Resilience & Depression Longitudinally (STRADL) cohort (n=280, 45% male, mean age= 62.1 (SD=4.1) years), the Dutch Famine Birth cohort (n= 151, 44% male, mean age 67.6 (SD=0.9) years), the Lothian Birth Cohort 1936 (LBC 1936, n= 865, 50% male, mean age 72.7 (SD=0.7) years), and the Simpson cohort (n=130, 31% male, mean age 78.5, (SD=1.5) years). This Thesis first examined associations between (i) cSVD burden (ii) total and regional brain volumes and (iii) self-reported symptoms of depression and anxiety measured using the Hospital Anxiety and Depression Scale. All analyses were adjusted for age, sex, hypertension, smoking behaviour, adult SES and cognition. Neither cSVD nor brain volumes were associated with symptoms of anxiety. Higher white matter hyperintensity volumes, having one or more cerebral infarct and increased cerebral atrophy were associated with increased depressive symptoms independent of vascular risk factors and adult SES. Secondly, this thesis examined associations between birth and childhood factors and cSVD burden and total and regional brain volumes. Each cohort was analysed individually and then all available data meta-analysed. All analyses were adjusted for age, sex, hypertension, smoking behaviour, adult SES and other early life factors. Meta-analysis found that increasing birth weight was associated with decreased risk of lacunes across all cohorts. Placental weight, which was only available for the Simpson cohort, was associated with decreased risk total cSVD, WMH severity and volume and cerebral infarcts. In the LBC 1936 and Simpson cohort increasing childhood and premorbid IQ and more years of education were associated with fewer cortical infarcts. The association between premorbid and childhood IQ and infarcts was independent of education level. Across three cohorts low education level was associated with more microbleeds. These findings suggest that factors other than traditional vascular risk factors may contribute to cSVD and structural brain changes in later life. Thirdly, this thesis examined associations between birth and childhood factors and self-reported symptoms of depression and anxiety measured using the Hospital Anxiety and Depression Scale (HADS) and the Quick Inventory of Depressive Symptoms (QIDS-16). All analyses were adjusted for age, sex, hypertension, smoking behaviour, adult SES and cognition In the Dutch Famine Birth Cohort people born before the famine had lower scores of depression and anxiety on the HADS compared to those exposed to famine in early gestation and those conceived after the famine. In the LBC 1936 increasing ponderal index was associated with lower depressive symptoms, increasing childhood and premorbid IQ were associated with lower symptoms of anxiety and depression. Lower educational attainment and some indicators of childhood SES were associated with higher symptoms of depression and anxiety. Overall results suggest that early life factors, particularly childhood IQ, may contribute to structural brain changes and symptoms of depression and anxiety in later life, independent of vascular risk factors and other early life factors. Efforts to understand factors which may contribute to late life health, from the earliest stages of life, are important and may be used to inform changes in social policy. The effect sizes and potential impact of these findings suggest that larger sample sizes with more vascular disease and more depression are needed to robustly test these associations.

Schools that implement a school uniform policy are on the rise (Musu-Gillette, Zhang, Wang, Zhang & Oudekerk, 2017). About 74% of these schools have a high population of low socioeconomic status students (Musu-Gillette et al., 2017) with about 75% or more qualifying for free or reduced lunch. The purpose of this study was to examine any relationships between students' perceptions of the effects of school uniforms and student socioeconomic status. In a charter school, a survey was completed by students to gather perception information and a separate survey by parents to gather socioeconomic status information. Hypotheses were tested using descriptive statistics and multiple regression models. Data were gathered from 184 students in grades 3 through 8. Examining individual survey items revealed older students were more likely to report that school uniforms help to reduce bullying and teasing. Another statistically significant difference was that some students of high socioeconomic status reported that uniforms help reduce arguments with parents about clothing (t(182) = 2.66, p<.01). Student responses on 10 survey items were grouped into one factor called School Climate, reflecting student perceptions on how uniforms affect the school's climate. Analyses revealed no significant relationships between the School Climate factor and socioeconomic status. However, Hispanic students reported a significantly more positive response overall than non-Hispanic students. These findings suggest students of various socioeconomic status perceive school uniforms similarly, but older students could be more likely to associate uniforms with a reduction in bullying. More research needs to be done in charter schools as little research has been done on school uniforms in charter schools, and among Hispanic students because the participation of Hispanic students was relatively low.

In the era of accountability in our nation‘s public schools, high-stakes standardized testing is the primary methodology for determining academic achievement; results from end-of-grade standardized testing are published annually in state and national report cards that are used as an instrument for determining school and teacher quality. What standardized tests do not take into consideration, however, are external environmental factors that have an impact on academic achievement; this research project focuses upon the effects of socioeconomic status on academic achievement on the middle grade student in North Carolina in 2012 and 2013. These years were chosen to comparatively analyze student achievement during the transition from the North Carolina Standard Course of Study to the Common Core curriculum. Only public schools configured in grades 6-8 that operate on a traditional school calendar were considered for this study. One way analyses of variance and paired samples t tests were performed to determine whether significant differences exist between student achievement in each grade level, academic year, and tested subject area (mathematics and reading) based on various levels of socioeconomic status levels within the school. Socioeconomic status levels were determined by the percentage of student population within the middle school that received free or reduced cost lunch during that school year. Significant differences existed between every socioeconomic level, subject area, and grade level, and significant differences also existed between each academic year as well as the number of economically disadvantaged students passing both the reading and mathematics assessments in each academic year. Schools with higher poverty levels scored significantly lower on both subject areas in both academic years than their wealthier counterparts. Test scores were also significantly lower in 2013 than in 2012, and fewer economically disadvantaged students passed both reading and mathematics in 2013 than in 2012. Further research is suggested to determine whether the trend of higher poverty schools performing significantly lower on standardized assessments than wealthier schools will continue with the ongoing implementation of the Common Core curriculum.

Obesity among children is a public health concern. Preschool-­‐aged children, especially those from low-­‐income families, are no exception to the obesity epidemic. During the RD Parent Empowerment Program, parents of Head Start children in Johnson City, TN completed a structured education program over the course of 4 workshops related to healthy habits of families. The goal was to empower parents to shop smart, cook healthy, and eat right. The Family Nutrition and Physical Activity (FNPA) screening tool was used as an assessment tool to evaluate behavior change over the course of the program. Improvement in overall FNPA score was seen at the conclusion of the program. Individual assessment of breakfast consumption, family meal patterns, fruit and vegetable intake, beverage choices, and restriction occurred. Participation in the RD Parent Empowerment Program resulted in maintaining healthy behaviors or improved behaviors for many participants. A larger sample may provide more conclusive results.

The purpose of this study was to determine if there was a difference between a student’s reading/language arts TCAP scale score and his or her lunch status for students in grades three, four, & five within two school systems in Tennessee. The population consisted of 2,442 students who were in grades three, four, and five during the 2014-2015 school year in a city school system in east Tennessee and a county school system in middle Tennessee. The Kruskal-Wallis H, a non-parametric test, was used to identify statistically significant differences in the medians of the reading/language arts TCAP scores across the three types of lunch payment status. The independent variable was the type of student lunch status (free, reduced, and full pay). The dependent variable was the reading/language arts TCAP scale score of students in grade three, four, and five. The quantitative findings revealed the relationship between student lunch status group and reading/language arts TCAP scale score was significant for all four research questions. In all analyses, the difference in the reading/language arts TCAP scale scores of students in the free lunch status group and the full pay lunch status group was significant. When the data from both school systems were combined, there was a significant difference in the scale scores between the free and full pay lunch status groups, the free and reduced lunch status groups, and the reduced and full pay lunch status groups.

The design method for this study was non-experimental quantitative. The survey was distributed via email to Kindergarten teachers in two Northeastern Tennessee school districts. There were 69 Kindergarten teachers who responded to the survey. The study revealed that Kindergarten teachers perceive that gender, socioeconomic status, and preschool experience have a significant impact on student readiness for school. Chronological age was not perceived to have an impact on student readiness for school to a significant extent. Kindergarten teachers perceived that preschool experience has the greatest impact on student readiness for school when asked to rank the order of impact from greatest to least. Chronological age was perceived to have a greater impact on student readiness for school than either socioeconomic status or gender.

Background and Objectives: It is estimated that over 40% of children in Ecuador are anemic. Anemia in children can influence physical and cognitive development and have lasting effects on adulthood productivity and quality of life. The objectives of this study were to: (1) evaluate the relationship of anemia and cognitive function, and (2) determine the influence of demographic factors on cognitive function. Population and Setting: The sample consisted of 175 school-aged children between 5 to 11 years old attending a school in a poverty stricken area of Guayaquil, Ecuador. Methods: A descriptive correlational cross sectional design was used to study the relationship between the level of anemia and the level of cognitive function. Other demographic factors were evaluated to determine their influence on cognitive function. Data were collected at the school using the Raven's Coloured Progressive Matrices to measure cognitive function and the STAT-Site MHgb Meter to measure hemoglobin levels. Results: No significant correlation was found between the level of anemia and cognitive function. Multiple regression analysis of demographic variables and cognitive function found age (Beta=0.56, t=8.6, p=0.000) and income (Beta=0.16, t=2.5, p=0.01) to be significant predictors of cognitive function. Interpretation and Conclusion: Many factors influence cognitive function and development. Additional research is needed to determine the effect of income level and related factors, such as parental time spent with the child doing homework, value placed on education in the home, education level of the parents, and quality of nutrition. Interventions to improve socioeconomic level, enhance parenting styles that foster cognitive development, and improve nutrition should be implemented.

Using a multilayered qualitative approach I draw from hermeneutical phenomenology informed by autoethnography through a case study to illuminate the culture and community of three elementary art rooms through the lens of socioeconomic status. Through my own story of having limited art education as a child from a rural working class background I simultaneously tell the story of students from three economically diverse schools in the same district. Focusing on their experiences within the space of the art room, I explore the ways children negotiate identity, notions of class, and interpret the shared district art curriculum. A rich description of each school along with interviews and conversations with children elicit important dialogue in terms of how the curriculum, in both hidden and overt ways, promotes a particular art aesthetic. Through a digestion of image, story and interviews with administrators, teachers and students this project focuses on the importance of action research and revealing one's own identity as a teacher and researcher as one attempts to unfold the multifaceted space of the art room. Front and center, this project calls for relevant and meaningful curriculum tied to the interests and lives of the children. My attempt is to tell the stories of the children I was privileged to work with for a semester. My research is intermingled with my experiences as a public school teacher for thirteen years, partnered with my own multifaceted identity as artist/child/working class/mother/student/teacher/middle class/learner.

Water treatment facilities across the United States are known for providing high-quality drinking water to their residents. However, differences in treatment methods, aging infrastructure, and outdated household plumbing may affect the quality of drinking water by the time it reaches the consumer’s tap. Palm Beach County, Florida, is an area with large socioeconomic contrasts where some families live in dilapidated structures and others reside in luxurious, gated communities. This research highlights the variation of household water quality by determining metal concentrations in tap water samples in communities of different socioeconomic status. In addition, interviews were conducted with personnel from five different Water Treatment Plants (WTPs) in the study area to understand the relationship between customers and their water utility. Results indicate that effective communication strategies are needed to boost public trust and fill critical information gaps about the water treatment process. Ninety-six tap water samples were collected from households throughout eastern Palm Beach County and analyzed for different metals using Inductively Coupled Plasma Optical Emission Spectrometry. Surveys were also administered at the same households where tap water samples were collected. Residents were asked about their perceptions of tap water and social and economic questions regarding their household characteristics. A Socioeconomic Status (SES) index was created using Principal Components Analysis (PCA) to understand how perceptions of tap water quality and concentrations of metals in household tap water vary based on SES. Results provide evidence that those living in the lowest-ranking SES neighborhoods are the least satisfied with their tap water quality and consume less tap water than those living in higher SES neighborhoods. Water quality results highlighted large variations in concentrations of aluminum (Al) and thus, analyses focused specifically on how Al concentrations varied according to SES. Results from Ordinary Least Squares regression show that as socioeconomic status decreases, the concentration of Al in tap water increases. Six samples exceed the State of Florida’s Secondary Maximum Contaminant Level (SMCL) for Al, and five of those samples were found in the lowest-ranking SES neighborhoods (SES 1 and 2). The results of this research provide evidence that inequities in household water quality exist across eastern Palm Beach County, Florida. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection
