Relationships among weight status, dairy food consumption, food and physical activity behavior, and nutritional status parameters of preschoolers in Tillamook County, Oregon

Frank, Sandra K. 14 May 2002 (has links)
The purpose of this cross-sectional population study was to provide an assessment of weight status of a county's preschool population utilizing the new growth charts and expressed as Body Mass Index, or BMI, -for- age percentile. This study was conducted in conjunction with an annual health screen for incoming kindergartners and consisted of two phases. The first phase involved assisting in the collection of, and statistically analyzing preschoolers' data collected during the Tillamook Health Screen on May 23-25th, 2001. Height, weight, blood pressure, hemoglobin, and blood lead levels were measured. Also, the preschoolers' parents completed a 24-hour food intake record and answered questions on mealtime habits. Phase Two consisted of a mailed questionnaire that was sent to parents of preschoolers who were screened in May, 2001, to investigate dairy food consumption, where meals are eaten, and physical activity habits of their preschoolers. Four significant findings were documented in this research. Foremost, Tillamook County preschoolers had a lower prevalence of healthy weight and a higher prevalence of at risk of overweight and overweight levels than children their age nationwide. Also, both systolic and diastolic blood pressure increased with increasing BMI-for-age percentiles for males and females. Third, hours spent viewing television—sedentary behavior—was positively related to BMI-for-age percentiles. The combination of more hours of physical activity with less television viewing time was inversely related to BMI-for-age percentiles. Last, Tillamook County preschoolers who were above the healthy weight range ate more Food Guide Pyramid servings of concentrated fats/sweets than children in the healthy weight range. Data that were not strong enough to reach conclusions about weight status related to dairy product consumption, fat content of dairy products, mealtime habits, meals eaten away from home, blood hemoglobin, and blood lead. Also, no significant associations were found between dairy food intake and blood hemoglobin, blood lead, or blood pressure. Even at preschool ages, physical activity and diet are important to assess when increasing rates of overweight levels and associated increases in blood pressure are being investigated. / Graduation date: 2003

Piped water access, child health and the complementary role of education : panel data evidence from South Africa

Wapenaar, Korstiaan Erich January 2017 (has links)
Thesis (M. Com. (Economics))--University of the Witwatersrand, Faculty of Commerce, Law and Management, School of Economic & Business Sciences, 2017 / This study establishes the causal impact of piped water access on child health in rural South Africa (2008 – 2015) through the use of a panel dataset and a quasi-experimental sample space. By employing an ordinal measure of child health as the dependent variable within ordinal probit, fixed and random effects, propensity-score matched difference-in-difference and system-GMM estimators, it is demonstrated that positive health benefits for children with access to piped water are observed if and only if the minimum level of educational attainment of the primary-caregiver is equal to or greater than 7 years. This finding of complementarity is demonstrated to be a function of an individual’s (in)capacity to evaluate water quality: people below this threshold suffer from a piped water bias, place insufficient weight on the observable characteristics of water when determining water quality and are subsequently less likely to treat piped water preceding consumption. The interactional effect estimates are statistically significant at the 5% level with the impact ranging from 1.617 to 2.008 levels. / GR2018

An analysis of health inspection as a component of school health service, in Kwazulu-Natal.

Memela, Daphne Thembile. January 2000 (has links)
Introduction In 1996 there were 1,847,440 pupils in 4007 primary schools in KwaZulu-Natal (KZN) who were targeted for school Health Inspection (HI). In the same year there were only 95 school health teams who were visiting schools for HI. The School Health Service (SHS) had been running on a racial basis since the Apartheid era of government, and needed to be reviewed in order to measure its effectiveness and to make it relevant to the new government and its new health policies. Purpose To review HI as a key component of School Health Services (SHS) and make recommendations to improve it's impact on the health of the school child and on health promotion in schools. Objectives To describe the structure, process, output and outcome of HI in KZN; to measure the impact of HI on the health of school children; and to calculate the SHS consultation cost and compare it with other primary health care services. Methodology A cross sectional study involving 21 schools covered by the SHS and 5 schools not covered by SHS was undertaken. The study area was KZN and the sample area was Indlovu region. All health authorities and racial groups participated in the study. Results A total of 212 children and 129 parents were interviewed. Of the children interviewed, 156 pupils (73.5%) had been involved in HI and 56 (26%) had not. The average nurse/pupil ratio was 1:49301. HI coverage was 62%. Of the 156 pupils examined, 108 were referred and 53% of them went for treatment. 93 % of parents interviewed gave a positive comment on HI and 24.8 % of them did not know their children's problems before they were informed by the SHN. Std. 5 pupils interviewed before and after HI were compared and it was found that 57% from the after-HI group went for treatment for their health problems compared to 53% before HI. Subjective feelings improved from 15% pain before HI to 0% after HI. Conclusion HI had a positive influence on encouraging pupils to seek recommended treatment and this is likely to improve their health. / Thesis (M.Med.)-University of Natal, Durban, 2000.

Longitudinal survey data analysis.

January 2006 (has links)
To investigate the effect of environmental pollution on the health of children in the Durban South Industrial Basin (DSIB) due to its proximity to industrial activities, 233 children from five primary schools were considered. Three of these schools were located in the south of Durban while the other two were in the northern residential areas that were closer to industrial activities. Data collected included the participants' demographic, health, occupational, social and economic characteristics. In addition, environmental information was monitored throughout the study specifically, measurements on the levels of some ambient air pollutants. The objective of this thesis is to investigate which of these factors had an effect on the lung function of the children. In order to achieve this objective, different sample survey data analysis techniques are investigated. This includes the design-based and model-based approaches. The nature of the survey data finally leads to the longitudinal mixed model approach. The multicolinearity between the pollutant variables leads to the fitting of two separate models: one with the peak counts as the independent pollutant measures and the other with the 8-hour maximum moving average as the independent pollutant variables. In the selection of the fixed-effects structure, a scatter-plot smoother known as the loess fit is applied to the response variable individual profile plots. The random effects and the residual effect are assumed to have different covariance structures. The unstructured (UN) covariance structure is used for the random effects, while using the Akaike information criterion (AIC), the compound symmetric (CS) covariance structure is selected to be appropriate for the residual effects. To check the model fit, the profiles of the fitted and observed values of the dependent variables are compared graphically. The data is also characterized by the problem of intermittent missingness. The type of missingness is investigated by applying a modified logistic regression model missing at random (MAR) test. The results indicate that school location, sex and weight are the significant factors for the children's respiratory conditions. More specifically, the children in schools located in the northern residential areas are found to have poor respiratory conditions as compared to those in the Durban-South schools. In addition, poor respiratory conditions are also identified for overweight children. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Poor access to water : the experiences of learners and educators within a rural primary school in Jozini, KwaZulu-Natal, South Africa.

Devnarain, Bhanumathi. January 2010 (has links)
Water is an indispensable basic human need which is protected by several provisions within legislation. However, despite extensive legislation access to water is problematic for many rural schools in South Africa. The achievement of the Millennium Development Goals and national goals that are time bound are not possible with the structural barriers that loom. This research study, sketches the experiences of learners and educators who have been exposed to poor access to water within a rural primary school in Jozini, KwaZulu-Natal, South Africa. This research study employs a qualitative research paradigm using a case study method to provide an in-depth understanding of the schooling context where there is poor access to water. The main aim was to explore in-depth how the schooling community is affected and what coping strategies are employed to deal with poor access to water. The research study was approached using ecological systems and social justice perspectives. Findings suggest that the consequences of poor access to water at school level are numerous and become even more complex when there is a lack of water at community level. In a compounding manner the consequences have the potential to, in the long term, have irreversible negative effects on learners and their potential to access quality education. Furthermore educators and management are placed in an invidious position to accommodate the challenges associated with poor access to water at school as part of their everyday teaching routine. Educators are failing to teach and learners are failing to learn thus the education system is rendered dysfunctional. The recommendations echo those of the participants who maintain that the community and the school must have access to water in order to improve the quality of life of all. Changes at the structural level in terms of how access to education is defined are a necessity. Co-operative governance, more stringent monitoring and evaluation of the education system, approaching education from a child-friendly perspective, adopting a human rights approach to fiscal spending and the involvement of chapter 9 institutions to ensure social justice are examples of the structural changes required and are part of the recommendations. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Durban, 2010.

Effects of an instructional resource on preschool children's physical activity levels / Nadine van Wyk

Van Wyk, Nadine, University of Lethbridge. Faculty of Education January 2011 (has links)
Children are not obtaining adequate amounts of physical activity (PA) and it is important to determine how we can increase PA. The purpose of this study was to explore the effect of a physical activity curriculum resource, Busy Bodies©, on preschool children’s physical activity levels. A total of five preschools from the NW quadrant of Calgary, Alberta were included in this study. The 48 participants involved in the study were all 4 years old. The preschools were divided into three groups: Control Group (no intervention), Intervention Group (school received the resource), and Intervention and Teacher Training Group (schools received the resource and teacher training). The researcher placed pedometers on all participants and observed selected participants using the System of Observing Fitness Instruction Time (SOFIT). The results of this study did not confirm that teacher training impacted physical activity levels. The effects of the resource on the Intervention and Intervention and Teacher Training groups were similar as derived from pedometer and direct observation. Alternative forms of teacher intervention may further increase physical activity. / x, 92 leaves ; 28 cm

The impact of employment on the health of South African children aged 6 to 60 months : a quantitative analysis of the 2008 National Income Dynamics Study.

Holst, Eirik Schmidt. January 2012 (has links)
This study’s main aim is to investigate the impact of adult household members’ employment on the health of children aged 6 to 60 months, with a particular focus on whether the gender of the employed adults matter. The study uses South African data from the nationally representative National Income Dynamics Study (NIDS), and children’s health will be measured using the two anthropometric indicators height-for-age and weight-for-age to indicate stunting and underweight respectively. The sample consists of about 1700 children, and both descriptive and econometric analysis are utilised to show correlations between child health outcomes and employment. The econometric analysis was performed using a logit model, and results show an association between employment in the household and child stunting, while no association is found between employment and child underweight. The main finding of the study is that living in households where one or more women (and no men) have employment reduces the likelihood of children being stunted. No health gain is found for living in households with only employed men, or living in households where both men and women have employment, relative to living in households where no one has employment. These results are robust to controlling for household expenditure per capita and a variety of other household characteristics. Employment thus seems to have a positive impact on children’s health, but the effect is only present in households where only females have employment. / Thesis (M.Dev.Studies)-University of KwaZulu-Natal, Durban, 2012.

Educator's understandings of the effects of hunger and malnutrition on learner's performance.

Ngcobo, Nelisiwe Rhonasia. January 2012 (has links)
This study aims to explore educators' understandings of the effects of hunger and malnutrition on learners' academic performance. The study reveals that there are various social conditions that contribute to poor learner performance at school such as poor family background, absenteeism due to hunger, diseases, pedagogic relationship and high levels of unemployment. It came to light from the study that, in spite of the attempts by the Department of Basic Education to eradicate hunger by, for example, providing child support grants and the Nutrition Programme, there are other challenges that hinder learners' progress. The study reveals that the majority of children are orphans and come from impoverished backgrounds. They come to school hungry without breakfast and without lunch-boxes. They do not have the educational materials that are needed by the educators. The study reveals that vulnerable learners, coming from impoverished backgrounds are victims of the situations as they face many problems that hinder their well-being, both at home and at school. The study also reveals that, if a child lives in poverty, that child might perform poorly at school. / Thesis (M.Ed.)-University of KwaZulu-Natal, Durban, 2012.

Body mass index, food choices, and nutrition knowledge and attitudes of fourth grade students in Wells County, Indiana : a comparison by school and grant year, 2003-04 through 2006-07

Hormuth, Laura J. January 2007 (has links)
In 2001, the percentage of fourth grade students who were overweight (26%) in Wells County, Indiana was twice the national average (13%). A Robert Wood Johnson Local Initiative Funding Partners grant was submitted and received to provide this community with resources to help combat unhealthy lifestyles. The purpose of this study was to examine differences in body mass index, food choices and nutrition knowledge and attitudes of fourth grade students in Wells County to determine if the prevalence of overweight had been reduced, and provide insight into children's food choices and nutrition knowledge. Of the 1,347 fourth grade students who completed the SPAN questionnaire over the four years, 23 percent were overweight. Over the four years, the prevalence of overweight did not increase to higher levels, providing modest support for the impact of Operation Wellness on students' weight. The students in this rural community ate fewer meals, snacked more frequently, did not eat enough fruits or vegetables, and ate too many high-fat/high-sugar foods compared to recommended standards. Students from the Southern Wells School District were significantly more aware of the relationship between diet, weight, and health than students in the other two school districts. / Department of Family and Consumer Sciences
