Research has suggested positive effects of nature immersion––a state of being or an act of doing in natural space––for urban children who were otherwise at risk of emotional or behavioral problems. However, few studies have systematically investigated natural space qualities that predict child well-being at the clinical level. The purpose of this study was to increase understanding of natural space qualities as factors of urban child well-being. Explanatory mixed-methods were used. Quantitative data (N = 174) included a survey and two parental-reports of child wellbeing. Interviews provided qualitative data (N = 15). Data were analyzed using: Generalized Linear Model and Content Analysis. Both data streams were merged into a point of meta-inference that contributed to parental assessment of enhanced child well-being: 1) Parental valuing of nature connection (p < 0.001) as a soothing and safe resource and 2) Shorter and more frequent nature-child space-time immersion (p < 0.001). Integration of natural spaces into urban environments may be a costeffective and meaningful way to address urban child well-being. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

Somatic complaints of children in primary care settings often go unexplained despite attempts to determine a cause. Recent research has linked violence exposure to stress symptomatology and associated somatic problems. Unknown, however, is whether specific physical symptom complaints can be attributed, at least in part, to violence exposure. Urban African-American 6- and 7-year-old children (N = 268), residing with their biological mothers, recruited before birth, and without prenatal exposure to hard illicit drugs participated. Children and mothers were evaluated in our hospital-based research laboratory, with teacher data collected by mail. Community violence exposure (Things I Have Seen and Heard), stress symptomatology (Levonn), and somatic complaints (teacher-and self-report items) were assessed. Additional data collected included prenatal alcohol exposure, socioeconomic status, domestic violence, maternal age, stress, somatic complaints and psychopathology, and child depression, abuse, and gender. Community violence witnessing and victimization were associated with stress symptoms (r= .26 and .25, respectively, p < .001); violence victimization was related to decreased appetite (r = .16, p < .01), difficulty sleeping (r = .21, p < .001), and stomachache complaints (r = .13, p < .05); witnessed violence was associated with difficulty sleeping (r = .13, p < .05) and headaches (r = .12, p < .05). All associations remained significant after control for confounding. Community violence exposure accounted for 10% of the variance in child stress symptoms, and children who had experienced community violence victimization had a 28% increased risk of appetite problems, a 94% increased risk of sleeping problems, a 57% increased risk of headaches, and a 174% increased risk of stomachaches. Results provide yet another possibility for clinicians to explore when treating these physical symptoms in children.

The United Nations has projected that Africa’s urban population will expand from fourth largest to becoming the second largest of the world’s regions by the year 2050. Patterns of migration and urbanisation have therefore been highlighted as significant focus areas for research and policy. Movement has the potential to result in improved living conditions and well-being, but may also reinforce inequalities and conditions of vulnerability. These consequences may pose particular risks in the case of children, and understanding the patterns, drivers and outcomes associated with child mobility is therefore critical. South Africa provides an important setting in which to explore child movements. The shift within the country from politically controlled migration to movement based on choice has resulted in high levels of mobility both to and within urban areas. Children have been shown to participate in such movements either independently or in conjunction with connected adults. However, there is currently little knowledge of the patterns and consequences of child residential mobility in South Africa, particularly within the urban environment. This PhD thesis attempts to address this research gap. Data from Birth to Twenty, a cohort of South African urban children living in Greater Johannesburg, was used to investigate three central research questions concerning residential mobility of cohort children over a 14 year period. Specifically, the thesis aimed to determine the frequencies and patterns of residential mobility observed over the first 14 years of the children’s lives, to examine the associations with mobility of children over a set of domains relating to the child, the child’s primary caregiver, and the child’s household and to assess the relationships between residential and school mobility and a set of educational outcomes. Routine data collected over the course of the Birth to Twenty study was supplemented with data from a Residential Move Questionnaire, administered to children’s primary caregivers in order to validate and provide additional information concerning the children’s residential movements over the time frame. The research objectives were achieved through the use of cross-sectional and longitudinal analysis techniques applied to these data. In particular, multilevel event-history analysis was used to model the children’s residential movements over time. Of the 3273 children enrolled into the cohort in 1990, two thirds of the children (64%) had moved home at least once by the time they reached 15 years of age. Nonetheless, a third of the children had never moved, indicating stability or a lack of opportunity for movement amongst this urban child population. Mobility was found to be more likely amongst children whose primary caregivers had no formal education and who lived in households with fewer assets and less access to services, suggesting that residential movement within this group of children was more common in the context of disadvantage. Extending these findings to an exploration of children’s educational outcomes revealed some unexpected results. The analyses provided evidence of a positive association between changes in residence and numeracy and literacy scores, and school mobility was found to be associated with grade repetition, however, a negligible relationship was found between residential mobility and school progression. In conclusion, mobility is associated with opportunities for some children in the cohort and challenges or hardships for others. However, even in the instance of movement connected to disadvantage, changes of residence did not prejudice children in terms of the educational outcomes investigated. This is suggestive of children’s possible resilience and adaptability in the face of change and highlights the potential for mobility to influence children’s lives positively. The findings concerning the relationship between mobility and child well-being run counter to trends observed in high-income countries and on that basis, the need for further research into dynamics associated with child mobility in other low- and middle-income country settings is highlighted. There is justification for monitoring child mobility in South Africa; mobility trends provide a valuable indicator of children’s living situations as well as the spatial and social changes occurring in the country more broadly.

The relationship between Executive Functions and Peer Rejection was explored. Thirty-Five students in an urban elementary school, (mean 10.7 years of age (sd=2.8), 34% male, and 88% African American) completed measures of executive functions: KABC-II Rover, The Wisconsin Card Sort and NEPSY-II Statue (below age 9) or The Iowa Gambling Task (age 9 and up). Classmates reported who was not a preferred play mate: a measure of rejection. Executive Functions were not significantly related to Rejection across the sample, but among the children with the lowest Executive Functions, The Wisconsin Card Sort was significantly negatively related to Rejection (-0.61, p = .04) suggesting poor Cognitive Flexibility may be a risk factor for Rejection. Performance on the Iowa Gambling Task was found to be positively correlated with Rejection (0.4, p = .008) suggesting that high impulse control may also be a risk factor for rejection among adolescents. This was consistent with a finding of a positive correlation between Office Discipline Referrals and popularity (.4, p = .008) among the sample. Implications for practice are also discussed including the difficulty of managing behavior when bad behavior is related to popularity.

Thesis (M. Sc.(Physiology)) -- University of Limpopo, 2019 / Aim: The purpose of this study was to assess the prevalence and risk factors associated with malnutrition and nutritional status of rural and urban primary school children aged 6–9 years. Literature background: Malnutrition is one of the leading causes of childhood morbidity and mortality in developing countries, affecting 10.9% of people globally, particularly in Southern Asian (15.7%) and sub-Saharan African (23.2%) countries undergoing urbanisation. Urbanisation affects diet, physical activity levels, body fatness, body composition and socio-economic factors. There is currently a shortage of information on the effect of urbanisation on nutritional status, especially in poor areas such as the Limpopo Province of South Africa. It is important to understand the effects that body fatness and associated risk factors have on stunting, wasting, underweight, and overweight/obesity in urban and rural children. Subjects and design: This was a cross-sectional study including rural (n=106) and urban (n=68) primary school children aged 6–9 years. Anthropometric (weight and height) and skinfold measurements were taken and a 24-hour recall dietary assessment was conducted twice to include a week day and a weekend day. A questionnaire was used to gather demographic, health, dietary and physical activity information. Results: The prevalence of stunting, wasting, underweight, and overweight/obese children in this population was 14%, 6%, 20%, and 26% respectively. Furthermore, the prevalence stunting, wasting, and underweight were higher in rural areas compared to urban areas. Meanwhile, the prevalence of overweight/obesity was higher in urban areas as compared to rural areas. Gender, area (urban/rural) (p=0.0001), birthweight, time spent on sedentary activities, monthly household income (p=0.0210), mode of transport to school, and breastfeeding (p=0.0560) were all found to be significantly associated with malnutrition. Weekday dietary intake of Vitamins A and D was significally associated with BF%, whereas weekend consumption of energy, protein, calcium, iron, phosphorus, and zinc were not significantly associated with BF%. The mean energy and calcium intake between the urban and rural vi population only differed significantly over weekends and not during the week, while vitamin D differed significantly between urban and rural populations during the week only. Conclusions: The current study demonstrates that children in rural areas were significantly more wasted than those residing in urban areas, while those residing in urban areas were significantly more overweight/obese compared to rural areas. All indicators used for undernutrition were associated significantly with gender and the prevalence were higher males compared to females, but this significance disappeared for overnutrition. Families with a higher income tended to have children who were overweight or obese compared to families with a lower income. Children spending a lot of time on sedentary activities were more likely to be overweight or obese, and breastfeeding seemed to protect children from becoming overweight or obese, while low birth weight was associated with stunting. The weekaday and week-end diets indicate that school feeding schemes in the rural areas may be effective in increasing total energy intake in children and this should be further investigated. In this population, stunting, wasting, and underweight were not limited to rural areas, and should still be a health concern in urban areas, despite the fact that overweight/obesity is also prevalent in urban areas. Thus, overweight/obesity in this population can be prevented by promoting breastfeeding and physical activity, while at the same time discouraging children from partaking in too many sedentary activities. / National Research Foundation (NRF)
