Immunization Rates (immunization + rate)
Selected AbstractsHigh Level of Immunity against Poliomyelitis in Albanian Refugees in Southern ItalyJOURNAL OF TRAVEL MEDICINE, Issue 3 2000P.L. Lopalco Background: The Apulia region (Southern Italy) may be considered a "border region" which, due to its position, has to face daily arrivals of refugees, especially from Albania. When the exodus of Albanians took place in 1991, a seroepidemiologic study revealed a low seroimmunity to poliomyelitis. In 1996, a large outbreak of paralytic poliomyelitis occurred in Albania. The aim of the study was to evaluate the poliomyelitis immunization level in a sample of Albanian refugees who arrived in the Apulia region between April and May 1997. Methods: Blood samples were obtained, after informed consent and on a voluntary basis, from 667 subjects housed in seven refugee camps in the Apulia region. Titration of neutralizing antibodies to the three polioviruses was carried out. Results: The findings showed that Albanian refugees had adequate levels of immunity to all polioviruses (95%for poliovirus type 1, 98.6%for poliovirus type 2 and 91.4%for poliovirus type 3). Moreover, a high immunization rate was found in all age groups irrespective of the areas of origin of the refugees and their socioeconomic conditions. Conclusions: Our findings show that Albanian refugees in Apulia region have adequate levels of immunity against polioviruses and confirm the effectiveness of mass vaccination campaigns with OPV conducted by WHO in Albania following an outbreak of poliomyelitis in 1996.

Despite numerous programs aimed at improving immunization rates among American children, under-immunization remains a significant problem. This study was conducted to gain insight into parents' /guardians' knowledge and attitudes regarding childhood immunizations. DESIGN AND METHODS. Thirteen African-American mothers and grandmothers participated in semistructured, audiotaped focus-group interviews. RESULTS. Four major themes emerged: health knowledge and beliefs about immunizations, system barriers that impede obtaining immunizations, facilitators that enhance obtaining immunizations, and suggestions for change. PRACTICE IMPLICATIONS. Immunizations are one of the most important health advantages available to children. Therefore, nurses must become aware of the problem of underimmunization and work to address some of the concerns caregivers have identified in this study. The health and lives of the nation's children depend on it. [source] The effect of lack of insurance, poverty and paediatrician supply on immunization rates among children 19,35 months of age in the United StatesJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 2 2008James L. Becton Jr MD Rational, aims and objectives, Previous studies found that the increasing number of paediatricians in the United States was associated with improved childhood immunization coverage, while the increasing poverty level and the lack of health insurance reduced access to health care. We evaluated whether changes in the number of paediatricians, poverty level and health insurance affected national childhood immunization coverage in the state levels of the United States. Methods, Data were collected primarily from the US National Immunization Surveys, series 4:3:1:3:3 from years 1995 and 2003. Ordinal logistic regression analysis was used to analyse the relationships among variables. Results, Over 8 years studied, immunization coverage increased for children aged 19,35 months from 52.3% to 79.8% in the 50 states. The average number of paediatricians per 1000 births increased 28.7% while the percentage of children without health insurance declined 15.6%, and the percentage of children who lived in poverty level declined 17.3%. In 1995, the states with higher immunization coverage were associated with higher numbers of paediatricians [odds ratio (OR), 32.73; 95% confidence interval (CI), 5.96,179.77]. In 2003, the higher numbers of paediatricians still played a role in the increased immunization coverage (OR, 4.69; 95% CI, 1.01,21.78); however, the higher rate of uninsured children in 2003 had an even greater effect upon immunization coverage. Compared with states with lower rates of uninsured children, states with intermediate and higher rates of uninsured children had sixfold (OR, 0.16; 95% CI, 0.03,0.81) and 16-fold (OR, 0.06; 95% CI, 0.01,0.40) decreased childhood immunization coverage, respectively. Conclusion, Between 1995 and 2003 in the United States, the lack of health insurance became more prominent than the supply of paediatricians in affecting immunization coverage for children aged 19,35 months. Future improvements in insurance coverage for children will likely lead to greater immunization coverage.

Kyrka Abstract A national cross-sectional seroprevalence survey was conducted in order to evaluate the current seroepidemiology of hepatitis A among 1,383 children, aged 0,14 years, residing in Greece. Stratification of the study population was conducted according to age and area of residence. Sera from study participants were tested for the presence of anti-HAV IgG antibodies. Immigrant children, as well as children residing in rural areas, had lower immunization rates. Among unvaccinated children, the seroprevalence rate of anti-HAV was 17.1%. Nationality was shown to have a marginally significant effect since non-immunized immigrant children had a higher seroprevalence rate (22.4% vs. 15.9%, OR,=,1.52, P,=,0.064). Significant differences between geographic areas for both vaccination coverage and natural immunity were observed. The study findings indicate that hepatitis A is prevalent in Greece and therefore universal infant hepatitis A immunization should be implemented. J. Med.

[source] Paediatric bronchiectasis in the twenty-first century: Experience of a tertiary children's hospital in New ZealandJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 2 2003EA Edwards Objective: Despite its decline in developed countries, bronchiectasis appeared to be a common diagnosis in Auckland, New Zealand children. The aims of this study were: to document the number of children in Auckland with bronchiectasis, their severity, clinical characteristics and possible aetiologies; to assess whether there was a relationship between ethnicity and poverty; and to estimate a crude bronchiectasis prevalence rate for New Zealand. Methods: A retrospective review of the case histories of all children attending a tertiary children's hospital in Auckland with bronchiectasis diagnosed by high-resolution chest computed tomography (CT) scan, during the period 1998,2000 was undertaken. Data collected included patient demographics, number of hospitalizations pre- and post-diagnosis, lung function tests, radiology and investigations. The New Zealand deprivation 1996 index was applied to the data to obtain a measure of socio-economic status. Results: Bronchiectasis was found to be common, with an estimated prevalence of approximately one in 6000 in the Auckland paediatric population. It was disproportionately more common in the Pacific Island and Maori children. In Pacific Island children, bronchiectasis not caused by cystic fibrosis was nearly twice as common in the general population than cystic fibrosis. Socio-economic deprivation and low immunization rates may be significant contributing factors. The bronchiectasis seen was extensive. Ninety-three percent had bilateral disease and 64% had involvement of four or more lobes on chest CT scan. A wide range of comorbidities and underlying aetiologies were evident. Conclusions: Paediatric bronchiectasis in Auckland, New Zealand, is common but underresourced. Only the most severe cases are being recognized, providing a significant challenge for paediatric health professionals. [source] Bronchiectasis in children: Orphan disease or persistent problem?,PEDIATRIC PULMONOLOGY, Issue 6 2002Charles W. Callahan DO Abstract More than a decade ago, bronchiectasis unrelated to cystic fibrosis was termed an "orphan disease", because it had become an uncommon clinical entity among children in the developed world. Bronchiectasis is more common among children in lower socioeconomic classes and in developing countries, presumably due to more frequent and recurrent respiratory infections, environmental airway irritants, poor immunization rates, and malnutrition. Reports from the Southern Pacific and from Alaska Native children reveal persistently high rates of childhood bronchiectasis. Better epidemiologic data throughout the world are needed to reassess the importance of this condition. The pathophysiology includes airway inflammation, mucus production, and regional airway obstruction, yet the reasons why some children develop bronchiectasis while other do not is unclear. The coexistence of asthma with bronchiectasis is associated with more severe disease, yet the impact of asthma therapy in children with both disorders has not been studied. Similarly, the pattern of antibiotic use for children with bronchiectasis varies by region with little data to justify one particular approach. It may be that public health measures aimed at improving living conditions for children and prevention of respiratory infections with antiviral vaccines will have more impact on childhood bronchiectasis than medical treatments in the future.
