Risk Factors for Emerging and Reemerging Infectious Diseases in ChildrenMurray, Meghan T. January 2019 (has links)
This dissertation assesses the factors that lead to the emergence of infectious diseases in children, particularly the emergence of multidrug-resistant organisms (MDROs) and diarrheal pathogens in vulnerable pediatric populations. It includes three manuscripts. The initial study is a systematic review that summarized the role of antibiotic exposure on the acquisition of MDROs in children. Twenty-nine studies met the inclusion criteria and a positive association between prior antibiotic use and subsequent colonization or infection with an MDRO was identified in most studies. There were wide variations among study sites, populations, and definitions of antibiotic use and MDROs. Therefore, limited inferences could be made on which components of antibiotic exposure have the greatest impact on MDRO development.
The second analysis examines the relationship between prior stay at a pediatric long-term care (LTC) facility and infection with an MDRO among hospitalized children. This study included 2,945 infections in 258,664 pediatric admissions from 2006 through 2016. At least 1 MDRO was identified in 10% of infections. Of the 1,198 children who had previously resided in a pediatric LTC facility, only 1 child (0.08%) had an MDRO infection. However, prior receipt of pediatric LTC was associated with an increased likelihood of infection (OR 2.4, CI95 1.66 – 3.43), C. difficile infection (OR 2.57, CI95 1.26 – 5.25), days of antibiotic use (OR 1.01, CI95 1.01 – 1.02), length of stay (OR 1.01, CI95 1.01 – 1.01), and death (OR 4.38, CI95 2.93 – 6.55).
The concluding study evaluates the association between animals living in or near the home and diarrheal disease in children. This research is a secondary analysis of the Global Enteric Multicenter Study case control study, which investigated the epidemiology of diarrheal illness in children <5 in sub-Saharan Africa and south Asia. Of 9,439 cases and 13,128 controls, 87% had ≥1 animal in their home. In a multivariable analysis adjusting for exclusive breastfeeding, water source, sanitation facility, number of children <5 years in the household, and wealth index, any animal on a child’s compound decreased the odds of diarrhea by 33% (aOR 0.66, CI95 0.59 – 0.74). However, children with diarrhea who had an animal present were not more likely to have a positive stool culture.
Overall, the three studies provide a thorough analysis of several factors associated with the infectious disease emergence in children, particularly as related to MDROs and diarrheal disease. Environmental characteristics, including antibiotic use and interaction with animals, were shown to be important factors for emergent infectious disease across diverse settings. The development of pediatric infection prevention interventions should take into consideration environmental risk factors in order to effectively mitigate the risks posed infectious disease emergence.

The prevalence of coronary risk factors among children, ages 11 to 13, in selected Western Cape schoolsDe Klerk, Danelle Ria 12 1900 (has links)
Thesis (MScSportSc)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Numerous studies have shown that coronary artery disease (CAD) has its origin in
childhood. Several risk factors that increase a person's risk for the development of CAD
are prevalent amongst children. South African statistics concerning the prevalence of
these risk factors are limited.
Research has shown that early intervention to eliminate risk factors can decrease the
risk for the development of CAD.
The purpose of this study was to determine the prevalence of certain coronary risk
factors amongst children aged 11 to 13 years in certain Western Cape schools. Certain
selected factors were tested. These included obesity, lack of physical activity,
hypertension, low physical fitness (V02max), a family history associated with an
increased risk, exposure to cigarette smoke, prevalence of diabetes mellitus and an
unhealthy diet.
The sample consisted out of 288 children and was made up by 154 boys and 134 girls.
Certain anthropometrical measurements (stature, weight, skinfoids, waist and hip
circumferences) were taken. Activity levels, family history, exposure to cigarette smoke,
prevalence of diabetes mellitus and diet, were measured by means of questionnaires.
Physical fitness (V02max) was tested with a three-minute step-test. A
sphygmomanometer was used to measure blood pressure. Depending on the
circumference of the child's arm, a paediatric or adult size cuff was used.
The results of the study showed that 22.01% of the boys and 59.7% of the girls had a
percentage body fat so high that it was considered a coronary risk factor. Physical
fitness levels were considered risk factors in 2.6% of the boys and 9% of the girls. A
very high percentage of the children tested had a family history associated with an
increased risk for the development of CAD (73.38% of the boys and 78.36% of the girls).
Systolic hypertension was prevalent among 22.01% of the boys and 23.13% of the girls. Diastolic hypertension was only prevalent among 5.19% of the boys and 5.97% of the
girls. Low activity levels were considered a risk factor in 31.17% of the boys and
39.55% of the girls. Out of all the subjects, 32.47% of the boys and 37.31% of the girls
were exposed to cigarette smoke on a daily basis.
The results of this study shows that certain coronary risk factors are quite common
amongst children. Prevention programmes that focuses on elimination of coronary risk
factors, such as hypertension, inactivity and obesity, is essential for the prevention of
subsequent coronary artery disease in adults. / AFRIKAANSE OPSOMMING: Verskeie studies het al bewys dat koronêre hartvatsiekte (KHS) reeds sy ontstaan het in
kinders van baie jong ouderdomme. Verskeie risikofaktore wat tot die latere ontstaan
van KHS lei kom ook onder jong kinders voor. Statistiek ten opsigte van die voorkoms
van hierdie risikofaktore onder kinders in Suid-Afrika is egter baie beperk.
Verskeie navorsing toon dat vroeë intervensie kan lei tot "n verlaging in risiko vir die
ontwikkeling van KHS op "n latere stadium.
Die doel van die studie was om die voorkoms van sekere koronêre risikofaktore in
kinders in Suid-Afrika te ondersoek. Sekere risikofaktore is ondersoek, dit het ingesluit,
obesiteit, lae fisieke aktiwitietsvlakke, hipertensie, lae fisieke fiksheid (V02maks), 'n
familie geskiedenis wat geassosieer word met "n verhoogte risiko, blootstelling aan
sigaret rook, die voorkoms van diabetes mellitus en "n swak dieet.
Die steekproef het bestaan uit 288 kinders waarvan 134 meisies en 154 seuns was.
Verskeie antropometriese meetings (lengte, massa, velvoue, middel- en heup
omtrekmates) is geneem. Aktiwiteitsvlakke, familiegeskiedenis, blootstelling aan
sigarette rook, voorkoms van diabetes mellitus en dieet is deur middel van vraelyste
vasgestel. Fisieke fiksheid (V02maks) is deur middel van "n drie-minuut-opstaptoets
vasgestel. Bloeddruk is met "n sfigmomanometer gemeet. Afhangend van die omtrek
van die kind se arm is "n pediatries- of volwasse-grootte drukband gebruik.
Persentasie liggaamsvet was by 22.01% van die seuns en 59.7% van die meisies so
hoog dat dit as "n risikofaktor beskou kan word. Fisieke fiksheidsvlakke kan by 2.6%
van die seuns en 9% van die meisies as "n risikofaktor beskou word. "n Baie hoë
persentasie van die kinders het "n familiegeskiedenis gehad wat geassosieer word met
"n verhoogde risiko vir die ontwikkeling van KHS (73.38% van die seuns en 78.36% van
die meisies). Sistoliese hipertensie het onder 22.01% van die seuns en 23.13% van die
meisies voorgekom. Diastoliese hipertensie het baie minder voorgekom as sistoliese
hipertensie (5.19% van die seuns en 5.97% van die meisies). Lae aktiwiteitsvlakke het onder 31.17% van die seuns en 39.55% van die meisies voorgekom. 'n Redelike hoë
persentasie van die kinders word daagliks aan sigaretrook van hulouers of oppassers
blootgestel (32.47% van die seuns en 37.31% van die meisies.)
Die resultate van die studie dui aan dat daar 'n redelike hoë voorkoms van sekere
koronêre risikofaktore onder kinders is. Ondersoek moet ingestel word na moontlike,
goed gestruktureerde intervensieprogramme.

Acute stress and strain due to backpack loading among primary school pupils.Abrahams, Sumaya. January 2011 (has links)
Schoolbag carriage represents a considerable daily occupational load for children (Negrini et al., 1999). Whittfield et al., (2001) and Puckree et al., (2004) have reported that the carriage of heavy schoolbags is a suspected aetiological factor of the daily physical stress of school pupils. Methods: One hundred and eighty-seven pupils voluntarily participated in a controlled, descriptive, epidemiological retrospective study. Subjects’ biographical, epidemiological, exercise history and lifestyle information was gathered by a self-report questionnaire (adapted from Puckree et al., 2004). Subjects’ body mass, stature and mass of their schoolbags were measured using a Detecto stadiometer scale. Digital images, electromyographical muscular activity and a posture profile assessments were captured in the frontal and sagittal planes whilst the pupils were in the loaded (carrying a schoolbag) and the unloaded phases (not carrying schoolbags). These images were analyzed using biomechanical software, Dartfish. The study being retrospective in nature recorded the prevalence of schoolbag carriage musculoskeletal pain over the last 12 months. Descriptive statistical tests such as mean, mode, frequency, percentages and inferential chi-square statistical test (set at a probability of 0.05) were employed to analyze the data. Results: The result indicated that 78.99% of the cohort experience musculoskeletal pain due to schoolbag carriage (p<0.0001). The most prevalent anatomical sites of pain were the shoulders (37.04%), neck (20.37%), lumbar (11.73%) and thorax (10.49%) (p<0.0001). The mean mass of the schoolbag carried by the cohort was 5.45kg which was approximately 11.5% of their body mass. The predisposing factors of the musculoskeletal pain were the methods employed to carry the schoolbag (single strap (20.21%) versus double straps (76.6%), altered posture due to excessive schoolbag mass together with a reduced craniovertebral angle (p<0.05).
Discussion & Conclusion: The excessive schoolbag mass carried by the pupils placed strain on the immature vertebral column of these pupils thus causing postural deviations which induced musculoskeletal pain and discomfort. / Thesis (M.Sport Sc.)-University of KwaZulu-Natal, Westville, 2011.

Exploring the Effects of Multi-Level Protective and Risk Factors on Child and Parenting Outcomes in Families Participating in Healthy Start/Healthy Families Oregon (HS/HFO)Nygren, Peggy 06 December 2013 (has links)
While many studies focus on the links between multiple risk factors and negative outcomes such as child maltreatment, less is known about the influence of protective factors in the face of risks. The theoretical base of this study was a social ecological model of interactive influences including individual parent, family, and neighborhood level factors to predict outcomes. Protective Factor Index (PFI) and Risk Factor Index (RFI) predictors were developed to explore potential multi-level protective factor buffering effects on key child development and parenting outcomes. Participants were first time mothers enrolled in a randomized controlled study of the Healthy Start/ Healthy Families Oregon (HS/HFO) home visitation program (treatment group) who completed a follow-up phone survey at the child’s 12 month birthday (n = 405). Families were offered HS/HFO services prenatally after meeting risk screening eligibility criteria on the New Baby Questionnaire (NBQ). Program mothers having received at least one home visit (n = 248) were included in the final analyses. Families had an average of 3.1 (SD = 1.2) NBQ risk factors at enrollment and 83% reported having trouble paying for basic needs. Families received an average of 16 home visits in the first 6 months of the program. Thirty-one percent of mothers were aged 19 or younger, 60% were White and Non-Hispanic, 31% were Hispanic, and 9% were another race/ethnicity. Hierarchical regression models with main effects (RFI, PFI, race) and an interaction term (RFI X PFI) were developed to predict eight outcomes. Interaction effects models were not significant. Five RFI main effects were significant: higher RFI scores were associated with greater likelihood of child welfare involvement, greater parenting stress, less favorable scores on child health and well-being, lower parent responsiveness and ii acceptance, and less supportive learning environments. One PFI main effect was significant: higher PFI scores predicted lower parenting stress. A trend level result showed higher PFI scores were associated with less child welfare involvement. Race was significant in two models: White/Non-Hispanic families were more likely to have a home visitor report child welfare involvement and had more frequent parent-child activities compared to other race/ethnicity families. Unpacking the results with separate single risk factor (12 items) and protective factor (10 items) regression models followed. Results showed parent’s prior family history of maltreatment and younger maternal age predicted child welfare involvement (home visitor report), while protection was seen for those with access to housing support. Social support and family functioning protectors were linked to lower parenting stress, while maternal depression showed the opposite finding. Better scores on a child health and well-being measure were seen with higher neighborhood cohesion and greater participation in HS/HFO; in contrast, neighborhood violence and frequent mobility were linked to worse scores. Developmentally supportive home environments were seen for families participating in additional parent support programs, in which the mother had greater knowledge of infant milestones and behavior, and if the family had access to housing supports. Unemployment proved to be associated with less enriched home environments. In summary, there was no support for the cumulative PFI in buffering risk for negative outcomes in this model. The RFI was also a more robust predictor of outcomes compared to the PFI in the main effects models. Overall, study findings provide some evidence for the utility of specific protective factors, as well as cumulative and specific single risk factors, for screening families for effectively targeting services and guiding the conceptual development of program and evaluation formats.
