[PMID: 36184529 DOI: 10.1016/j.pedneo.2022.06.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 06/02/2022] [Accepted: 06/14/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Children hospitalized with infectious diseases may develop severe, life-threatening conditions, often requiring admission to pediatric intensive care unit (PICU). The objectives of this study were to identify independent risk factors for PICU hospitalization with an infectious disease in children <5 years of age. METHODS In southern Israel, two populations live side by side: the middle-high income Jewish population and the low-income Bedouin population, both receiving equal and free medical care at the only tertiary medical center in the area. The study population included all children born in southern Israel and hospitalized at PICU with an infectious disease during 1991-2012. Risk factors for PICU hospitalizations were retrospectively studied by Kaplan-Meier and Cox proportional hazard survival analyses. RESULTS 9951 Jewish children and 18,002 Bedouin children were enrolled; overall, 1135 episodes of PICU hospitalizations with an infectious disease were recorded (879, 77.4% Bedouin and 256, 22.6% Jewish patients). Bedouin children had a higher risk for PICU hospitalization with an infectious disease compared with Jewish children (adjusted Hazard Ratio [adj. HR] 1.7, 95% CI 1.5-2.0); maternal multiparity and low-birth weight (<2500 g) were additional risk factors for PICU hospitalization with an infectious disease compared to firstborns (adj. HR = 1.2, 95% CI 1.0-1.5) or to children with a birth weight ≥2500 g (adj. HR = 1.5, 95% 1.2-1.9). Older age was a protective factor for PICU hospitalization (adj. HR = 0.98, 95% CI 0.97-0.99). Children hospitalized with a central nervous system infection had the highest risk of PICU hospitalization (adj. HR 6.8, 95% CI 5.5-8.4), followed by those with urinary tract infections (UTI, adj. HR 3.1, 95% CI 2.5-3.8) and those with lower respiratory tract infections (LRTI, adj. HR 2.9, 95% CI 2.4-3.4). CONCLUSION Bedouin ethnicity, low birth weight, maternal multiparity and younger age were significant risk factors for PICU hospitalizations with an infectious disease. Among the infectious diseases analyzed, CNS infection had the highest risk for PICU hospitalization, followed by UTI and LRTI.

Abstract
OBJECTIVE To investigate the impact of neighborhood conditions on respiratory-related hospital admissions in the first year after discharge from the neonatal unit in a population of infants born very preterm with bronchopulmonary dysplasia (BPD). STUDY DESIGN Very preterm infants (gestational age <33 weeks) who had BPD at 36 weeks postconceptional age and who received follow-up in a French regional medical network were included. Socioeconomic context was estimated using a neighborhood-based Socioeconomic Deprivation Index. Poisson regression analysis was used to identify risk factors associated with rehospitalization. RESULTS The study included 423 infants with a mean gestational age of 27 ± 2 weeks and mean birth weight of 941 ± 277 g; 51% of the population lived in a disadvantaged area. The hospital admission rate was increased by 8.8% for infants living in affluent areas and by 24% for those living in disadvantaged areas (P <.01) and reached 30% in extremely preterm infants from disadvantaged areas. After adjusting for perinatal characteristics, home oxygen therapy, and season of birth, the respiratory-related hospitalization rate was almost 3-fold higher in infants living in disadvantaged areas, with an adjusted incidence rate ratio of 2.79 (95% CI, 1.29-6.09; P <.01). CONCLUSIONS Disadvantaged neighborhoods adversely impact early respiratory outcomes in infants born very preterm with BPD. The social context should be considered in routine follow-up care of children born preterm. Further studies investigating the underlying mechanisms are warranted for implementing preventive strategies.

Abstract
AIM This study explored the differences in demographic and socio-economic factors between children hospitalised due to four common viral infections. METHODS Demographic data were obtained from Statistics Sweden on >3000 children admitted to Astrid Lindgren Children's Hospital in 2009-2014 with rotavirus, influenza, respiratory syncytial virus (RSV) or chickenpox. We compared demographic and socio-economic factors between case groups using logistic regression with rotavirus cases as reference. RESULTS There were differences in the median age at admission; RSV cases were younger (0.4 years), influenza (2.4 years) and chickenpox cases (2.7 years) older than rotavirus cases (1.2 years). RSV, influenza and chickenpox cases lived in families with more children than rotavirus cases. RSV and influenza cases were more likely to have underlying chronic conditions. Mothers of RSV cases were more likely to be born in Sweden. Further socio-economic differences were not robustly confirmed in sensitivity analyses. CONCLUSION We found a few differences in demographic factors between children hospitalised with the four common infections, which were mainly explained by the epidemiology and transmission patterns of these infections.

Abstract
BACKGROUND It is unclear to what extent socioeconomic inequalities exist in common infectious diseases in high-income countries. We aimed to explore educational differences in five common acute infectious diseases in adults in the Netherlands. METHODS As part of a year-round repeated cross-sectional health survey, adults aged 25 and older were asked if they had experienced acute upper or lower respiratory tract infections, acute otitis media, urinary tract infections or gastro-enteritis in the two previous months. If so, participants were asked whether they had consulted their general practitioner and if they had been unable to perform their normal daily activities. These outcomes were analyzed per highest attained level of education. RESULTS Data of 18 629 survey respondents were used in the analyses. People with a low educational level had lower odds of upper respiratory tract infections (OR 0.88, 95% CI 0.81-0.95), but higher odds of lower respiratory tract infections (OR 1.57, 95% CI 1.16-2.11). After adjustment for several covariates, the differences in upper respiratory tract infections remained statistically significant (aOR 0.84, 95% CI 0.77-0.91). The educational differences in lower respiratory tract infections were mitigated by adjusting for chronic diseases and health behaviours. For all infectious diseases, the likelihood of general practitioner consultation was highest for the lower educated group. Inability to work or perform normal daily activities due to an infectious disease was similar across all levels of education. CONCLUSION This study shows that educational differences in incidence and care seeking behaviours exist for common acute infectious diseases in the Netherlands.

Abstract
In Panama, epidemiological data on congenital toxoplasmosis are limited, making it difficult to understand the scope of clinical manifestations in the population and factors that may increase the risk of infection. This study provides insight into the epidemiological situation of maternal and congenital toxoplasmosis in Panama and contributing information on the burden of this disease in Central America. Blood samples were collected from 2326 pregnant women and used for the detection of anti-T. gondii antibodies. A high seroprevalence (44.41%) was observed for T. gondii infection in pregnant women from different regions of Panama, with an estimated incidence rate of congenital toxoplasmosis of 3.8 cases per 1000 live births. The main risk factors associated with T. gondii infection using bivariate statistical analysis were an elementary level education and maternal age range of 34-45 years. Multivariate statistical analyses revealed that in some regions (San Miguelito, North and West regions), the number of positive cases correlated with the presence of pets, stray dogs and the consumption of poultry. In other regions (East and Metropolitan regions), the absence of pets was considered a protective factor associated with negative cases, while the presence of stray cats and the age range of 25-34 years did not represent any risk in these regions.

Abstract
INTRODUCTION The immunosuppressive properties of PFASs are widely recognized. Early-life exposure to PFAS has been linked to reduced immune response to childhood vaccinations and increased rates of common infectious diseases, but implications for hospitalizations are unclear. OBJECTIVES To investigate the association between maternal serum concentrations of five PFASs during pregnancy and the child's rate of hospitalization due to common infectious diseases between birth and 4 years of age. METHODS Serum samples from first trimester pregnant women from the Odense Child Cohort (OCC) collected in 2010-2012 were analyzed for concentrations of perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and three other PFASs. Data on child hospitalizations with an ICD-10 code for infectious disease was obtained from the Danish National Patient Register. The following were identified: upper respiratory tract infections (URTI), lower respiratory tract infections (LRTI), gastrointestinal infections (GI), and other infections. The Andersen-Gill Cox proportional hazard model for recurrent events was used to investigate the association between PFAS exposure and hospitalizations. The resulting estimates were hazard ratios (HRs), which express the relative change in the instantaneous risk of hospitalization with a doubling in maternal PFAS concentration. RESULTS A total of 1,503 mother-child pairs were included, and 26% of the children were hospitalized at least once for infectious disease. A doubling in maternal PFOS concentration was associated with a 23% increase in the risk of hospitalization due to any infection (HR: 1.23 (95% CI: 1.05, 1.44). There was indication of an interaction between child sex and PFOS (p = 0.07) and PFDA (p = 0.06), although in opposite directions. Further, every doubling of PFOA or PFOS increased the risk of LRTI by 27% (HR: 1.27 (1.01, 1.59)) and 54% (HR: 1.54 (1.11, 2.15)), respectively. Similar tendencies were seen for URTI and the group of other infections. For GIs, the opposite pattern of association was seen as HR's were consistently below 1 (PFOA, HR: 0.55 (0.32, 0.95)). DISCUSSION We found an association between PFOS and the overall risk of infectious disease, and between PFOS and PFOA exposures and the risk of LRTI's. These results are in agreement with previous findings from the OCC, in which maternal PFOS and PFOA concentrations were positively associated with the number of days that the children experienced fever, thereby suggesting that PFOS and PFOA may affect the prevalence of both mild and more severe infectious diseases even in a rather low-exposed population.

Abstract
Objectives: Health status is associated with socioeconomic status (SES) of the individuals. The aim of this study was to identify any link between the SES and influenza-like illness (ILI). Materials and Methods: This observational case-control study was done on 18–70 years old patients presented with ILI (cases) at tertiary care hospital of western India. Controls were selected from demographically matched elective surgery patients except the SES. SES was evaluated as per the Modified B G Prasad 2017 scale and participants were further classified in lower SES (per capita income <2000 INR) and non-lower SES groups. Results: 810 cases and 830 controls were compared. Many cases were from lower SES, had poor hand hygiene, and were using soil, mud, ash (SMA) for hand cleaning as compared to the control. Among the cases significant numbers were from lower SES (543/810[67%], P < 0.02), many were alcoholics, smokers, had poor hand hygiene, were using SMA for hand cleaning, and had preexisting chronic obstructive pulmonary disease (COPD), while few were having diabetes in the lower SES group as compared to the non-lower SES group. ILI was more common among lower SES class in unadjusted analysis (odds ratio [OR] 1.58, 95% CI 0.89–2.76) and the results were significant even after the adjustment of covariates (OR 1.62, 95% CI, 0.94–2.85). Conclusion: Lower SES people were 2.8 times more prone to ILI as compared to the age- and sex-matched control in western part of India.

Abstract
BACKGROUND Studies on the association between breastfeeding and infections in children beyond the first year of life reveal conflicting results. In a population-based birth cohort, we investigated whether the duration of breastfeeding was associated with the number of hospitalizations due to infection and symptoms of infection at home. METHODS In the Odense Child Cohort, text message questionnaires were used to register information on breastfeeding (weekly until end of weaning) and symptoms of infection (biweekly; 12-36 months of age). Hospitalization data were obtained from the Danish National Patient Registry. RESULTS Of the 1087 invited, 815 mother-infant pairs were included. The median duration of any breastfeeding was 7.6 (interquartile range: 3.5-10.4) months and of exclusive breastfeeding was 2.1 (interquartile range: 0.7-4.4) months. Hospitalization due to infection was seen in 207 (25.4%) infants during the first 3 years of life. The adjusted incidence rate ratio (IRR) for hospitalization due to any infection decreased with a longer duration of any breastfeeding (adjusted IRR: 0.96; 95% confidence interval 0.93-0.99; P < .001). The strongest associations between the duration of any breastfeeding and hospitalizations due to infection were found within the first year of life, for lower respiratory tract infections, and other infections (P ≤ .05). For infants exclusively breastfed, the adjusted IRR for hospitalization was 0.88 (95% confidence interval: 0.80-0.96; P = .006). No protective associations were present between breastfeeding and infection symptoms registered at home from ages 12 to 36 months. CONCLUSIONS The results suggest that increased duration of breastfeeding, especially exclusive breastfeeding, protects against infections requiring hospitalization in the first year of life but not hospitalizations or symptoms of infection at home beyond the first year.

Abstract
PURPOSE To describe the demographics and clinical characteristics of pediatric uveitis and scleritis at a tertiary eye care center. METHODS Clinical records of children with either uveitis or scleritis that presented between January 1989 and January 2016 were reviewed retrospectively. RESULTS Seventy-three patients were identified. Fifty-four had uveitis and 19 had scleritis. Posterior uveitis was the most common (27.8%), followed by intermediate uveitis (25.9%), panuveitis (25.9%) and anterior uveitis. Majority were noninfectious uveitis (37.0%), and 29.6% were idiopathic. Common associations were sarcoidosis (14.8%), HLA-B27 haplotype (9.3%) and toxoplasmosis (7.4%). Posterior scleritis was more common (94.7%) than anterior scleritis and majority were idiopathic (68.4%). Delayed patient presentation and presenting visual acuity worse than 0.3 LogMAR were associated with poor visual outcome (p = .03; OR = 0.17; 95% CI, 0.03-0.84 and p = .007; OR = 0.09; 95% CI, 0.02-0.52 respectively). CONCLUSION Majority had noninfectious etiologies. Uveitis associated with juvenile idiopathic arthritis was rare.

Abstract
BACKGROUND The season in which a child is born may affect the immune system development and thereby influence the risk of infections. In this study, we examined the associations between birth season and the risk of hospital admission or symptoms associated with a wide range of infections. METHODS This study is a prospective cohort study of 2434 children with an average follow-up of 3.5 years. Admission data were obtained from the Danish National Patient Registry. Via short message service (SMS) questionnaires, 1279 families reported symptoms of infections in a 1-year period. RESULTS Of the 2434 children, 639 (26.3%) were admitted to the hospital, and the children experienced on average 64.4 days with symptoms of infection within 1 year. There was no association between birth season and hospital admissions due to all infectious causes [incidence rate ratio (IRR) = 0.89; 95% confidence interval (CI), 0.65-1.22; P = 0.471]. However, children born in the fall had a higher IRR for admission due to all infectious causes when excluding admissions within the first year of life. Winter- and spring-born children had lower IRRs for admission due to gastrointestinal infections than summer-born children, but this association was alone present when admissions within the first year of life were included. The short message service-survey showed significantly lower IRRs for any symptom of infection among winter-born (IRR = 0.85; 95% CI, 0.75-0.96; P = 0.009) and fall-born children (IRR = 0.88; 95% CI, 0.78-0.99; P = 0.033) in comparison with summer-born children. CONCLUSIONS Birth season was not associated with hospital admission due to all infectious causes within the first 5 years of age; however, fall-birth was associated with a higher IRR for admissions due to all infectious causes after the first year of life. The association between birth season and admissions due to gastrointestinal infections was only seen when including children admitted under the age of one. Being born in fall or winter was associated with a decreased IRR for number of days with any symptom of infection registered at home.

Abstract
AIM We examined the frequency and potential risk factors for respiratory infections, diarrhoea and absences in infants during their first months in day care. METHODS This prospective cohort study comprised 269 Danish infants aged eight months to 14 months and was part of a study that examined how probiotics affected absences from day care due to respiratory and gastrointestinal infections. The risk factors examined were the household, child characteristics and type of day care facility. Parents registered upper respiratory tract infections (URTIs), lower respiratory tract infections (LRTIs), diarrhoea and day care absences on web-based questionnaires. RESULTS Over a mean of 5.6 months in day care, 36% and 20% of the infants had at least one URTI or LRTI, and 60% had diarrhoeal episodes. The risk of at least one URTI was increased by previous respiratory infections, with an odds ratio (OR) of 2.65, but was inversely associated with having a pet (OR: 0.43), being cared for by registered child minders compared to day care centres (OR: 0.36), birthweight (OR 0.40) and age at day care enrolment (OR: 0.64). No significant risk factors for LRTIs and diarrhoea were found. CONCLUSION Infection risks were associated with environmental factors and factors related to the child.

Abstract
OBJECTIVES Early diagnosis of childhood cancer is critical. Nevertheless, little is known about the potential role of inequality. This study aims to describe the use of primary care 2 years before a childhood cancer diagnosis and to investigate whether socioeconomic factors influence the use of consultations and diagnostic tests in primary care. DESIGN A national population-based matched cohort study. SETTING AND PARTICIPANTS This study uses observational data from four Danish nationwide registers. All children aged 0-15 diagnosed with cancer during 2008-2015 were included (n=1386). Each case was matched based on gender and age with 10 references (n=13 860). PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was additional rates for consultations and for invoiced diagnostic tests for children with cancer according to parental socioeconomic factors. Furthermore, we estimated the association between socioeconomic factors and frequent use of consultations, defined as at least four consultations, and the odds of receiving a diagnostic test within 3 months of diagnosis. RESULTS Children with cancer from families with high income had 1.46 (95% CI 1.23 to 1.69) additional consultations 3 months before diagnosis, whereas children from families with low income had 1.85 (95% CI 1.60 to 2.11) additional consultations. The highest odds of frequent use of consultations was observed among children from low-income families (OR: 1.94, 95% CI 1.24 to 3.03). A higher odds of receiving an invoiced diagnostic test was seen for children from families with mid-educational level (OR: 1.46, 95% CI 1.09 to 1.95). CONCLUSION We found a socioeconomic gradient in the use of general practice before a childhood cancer diagnosis. This suggests that social inequalities exist in the pattern of healthcare utilisation in general practice.

Abstract
BACKGROUND Infections are the leading cause of morbidity and mortality in children. Caesarean section as a potential risk factor for infection has recently gained interest. Delivery by caesarean section has increased greatly, with nonmedical reasons playing an increasing role. We aimed to analyze the association between mode of delivery and hospitalizations because of infection and symptoms of infection at home in early childhood. METHODS A cohort study, based on the Odense Child Cohort, following infants from gestation until a mean age of 3.5 years. Data on hospitalization because of infections were collected from the Danish National Patient Registry. Data on symptoms of infection at home were collected via a text message-based questionnaire. RESULTS A total of 1921 children were born by vaginal delivery, 283 by elective caesarean section and 227 by acute caesarean section. An adjusted regression model showed an incidence rate ratio for hospitalizations because of infection in children born by elective caesarean section compared with children born by vaginal delivery of 1.45 (95% confidence interval: 1.16-1.80; P = 0.001). The analyses on symptoms of infection at home found no associations between any symptom of infection and mode of delivery. Symptom-specific subanalyses showed contrasting results. CONCLUSIONS Mode of delivery showed a strong association to hospitalization because of infectious disease during early childhood. Overall, no association was present between rate of symptoms of infection at home and mode of delivery.

Influence of Socioeconomic Context on the Rehospitalization Rates of Infants Born Preterm. J Pediatr 2017; 190:174-179.e1.

Abstract
OBJECTIVE To investigate the impact of social inequalities on the risk of rehospitalization in the first year after discharge from the neonatal unit in a population of preterm-born children. STUDY DESIGN Preterm infants were included if they were born between 2006 and 2013 at ≤32 + 6 weeks of gestation and who received follow-up in a French regional medical network with a high level of healthcare. Socioeconomic context was estimated using a neighborhood-based socioeconomic deprivation index. Univariate and logistic regression analyses were used to identify risk factors associated with rehospitalization. RESULTS For the 2325 children, the mean gestational age was 29 ± 2 weeks and the mean birth weight was 1315 ± 395 g. In the first year, 22% were rehospitalized (n = 589); respiratory diseases were the primary cause (44%). The multiple rehospitalization rate was 18%. Multivariable analysis showed that living in the most deprived neighborhoods (socioeconomic deprivation index of 5) was associated with overall rehospitalization (OR, 2.2; 95% CI, 1.5-3.6; P <.001), and multiple rehospitalizations (OR, 2.5; 95% CI, 1.2-4.9; P <.01); with socioeconomic deprivation index of 1 (least deprived) as reference. Deprivation was associated with all causes of hospitalization. Female sex (P <.001) and living in an urban area (P = .001) were protective factors. CONCLUSIONS Despite regional routine follow-up for all children, rehospitalization after very preterm birth was higher for children living in deprived neighborhoods. Families' social circumstances need to be considered when evaluating the health consequences of very preterm birth.

Abstract
Objectives The aim of this study was to investigate national prevalence, general demographic characteristics and survival of Danish patients with Ehlers-Danlos syndrome (EDS). Method A population-based cohort study was conducted using a database consisting of the entire Danish population alive at any given time between 1 January 2000 and 31 December 2012, based upon longitudinal Danish national registers. All patients with EDS were identified, and the cohort was described by disease prevalence, basic demographic characteristics, mean age at death and mortality for the observational period of 13 years. Results The cohort held 1427 unique persons with EDS, giving a national prevalence of 0.02%. The EDS population had a mean ( s . d .) age of 34.9 (18.6) years and comprised 73.9% females and 26.1% males. Of the cohort, 95.9% originated from Denmark and 57% were unmarried. We found that 31.6% of the cohort received state-granted subsidies, of which 77% were in the form of early retirement pension. Regarding educational status, 28.1% of the EDS cohort had completed primary education (⩽10th grade) as their highest educational level, while 71.9% had completed a higher level. During the observation period, 42 patients died, with a mean ( s . d .) age at death of 53.6 (21.7) years. Conclusion This study confirmed a small national prevalence of patients diagnosed with EDS and showed that the majority of patients diagnosed are female. The EDS cohort had a lower educational level, mean age and life expectancy compared with the background population and showed a predisposition for receiving state-granted subsidies.

Abstract
BACKGROUNDS Respiratory tract infections (RTIs) are a common cause of morbidity and mortality in young children and can be associated with wheeze. Vitamin D can have a protective role against RTI. MATERIALS AND METHODS A systematic search of PubMed, Embase and the Cochrane library was performed. Titles and abstracts were evaluated, and selected articles were reviewed by 2 authors. We included randomized controlled trials (RCTs) investigating the effect of vitamin D supplementation during pregnancy on RTIs or wheeze in children of 5 years of age or younger. Observational studies on the association between serum 25-hydroxyvitamin D during pregnancy, or at birth, and RTIs and/or wheeze were included. The protocol was registered on PROSPERO (Registration number: CRD42015019183). RESULTS Of 4 RCTs, 1 showed a protective effect of a high daily dose (2000 IU) of vitamin D during pregnancy on offspring RTI doctor visits (P = 0.004; the RCT also included 800 IU/d supplement to the infants until 6 months). Meta-analysis of 3 RCTs showed a reduced relative risk for offspring wheeze when mothers were supplemented with vitamin D during pregnancy [relative risk: 0.81 (95% confidence interval: 0.68-0.97), P = 0.025]. In 3 of 4 strong-quality, and 5 of 10 moderate-quality observational studies, an inverse association between pregnancy and cord 25-hydroxyvitamin D and subsequent wheeze and/or RTI was seen. CONCLUSION Growing evidence supports a preventive role of vitamin D during pregnancy on offspring wheeze and/or RTI. Recommendations in future intervention studies may need to exceed current recommendations of vitamin D supplementation during pregnancy to show benefit against childhood wheeze or infections.

Abstract
AIM Infectious disease (ID) hospitalisation rates are increasing in New Zealand (NZ), especially in pre-school children, and Māori and Pacific people. We aimed to identify risk factors for ID hospitalisation in infancy within a birth cohort of NZ children, and to identify differences in risk factors between ethnic groups. METHODS We investigated an established cohort of 6846 NZ children, born in 2009-2010, with linkage to a national data set of hospitalisations. We used multivariable logistic regression to obtain odds ratios (OR) for factors associated with ID hospitalisation in the first year of life, firstly for all children, and then separately for Māori or Pacific children. RESULTS In the whole cohort, factors associated with ID hospitalisation were Māori (OR: 1.49, 95% CI: 1.17-1.89) or Pacific (2.51; 2.00-3.15) versus European maternal ethnicity, male gender (1.32; 1.13-1.55), low birthweight (1.94, 1.39-2.66), exclusive breastfeeding for <4 months (1.22, 1.04-1.43), maternal experience of health-care racism (1.60, 1.19-2.12), household deprivation (most vs. least deprived quintile of households (1.50, 1.12-2.02)), day-care attendance (1.43, 1.12-1.81) and maternal smoking (1.55, 1.26-1.91). Factors associated with ID hospitalisation for Māori infants were high household deprivation (2.16, 1.06-5.02) and maternal smoking (1.48, 1.02-2.14); and for Pacific infants were delayed immunisation (1.72, 1.23-2.38), maternal experience of health-care racism (2.20, 1.29-3.70) and maternal smoking (1.59, 1.10-2.29). CONCLUSIONS Māori and Pacific children in NZ experience a high burden of ID hospitalisation. Some risk factors, for example maternal smoking, are shared, while others are ethnic-specific. Interventions aimed at preventing ID hospitalisations should address both shared and ethnic-specific factors.

Abstract
BACKGROUND Although most research on infectious diseases (IDs) has focused on hospitalizations, this provides an incomplete picture of healthcare utilization. We describe the burden and epidemiologic features of ID-related emergency department (ED) visits among U.S. children. METHODS We conducted a cross-sectional analysis of the Nationwide Emergency Department Sample, a nationally representative sample of ED patients. We identified children who presented to the ED with a primary diagnosis of ID. Outcome measures were ID-related ED visits, hospitalizations through the ED and ED charges. RESULTS During 2011, we identified 1,914,509 ID-related ED visits among U.S. children, corresponding to a weighted estimate of 8,524,357 ED visits. This accounted for 28% of all ED visits by children. The frequency of ID-related ED visits was 10,290 visits per 100,000 children. The most common diagnoses were upper respiratory infection (41%), otitis media (18%) and lower respiratory infection (14%). Overall, 62% of ID-related ED visits were made by children with Medicaid; 35% were by those in the lowest income quartile. Among the ID-related ED visits, 424,725 (5%) resulted in hospitalization, with 513 hospitalizations per 100,000 children. The most common reason for hospitalization was lower respiratory infection, which accounted for 40% of all ID-related hospitalizations from the ED. Median charge per ED visit was $718, with total annual charges of $9.6 billion. CONCLUSIONS The public health burden of IDs, as measured by ED visits, subsequent hospitalizations and associated charges, was substantial. We also found that children with markers of lower socioeconomic status comprised a disproportionately high proportion of ID-related ED visits.

Abstract
BACKGROUND The primary aim of this study was to assess the effect of immigrant status on Emergency Room (ER) utilisation by children under age one, considering all, non-urgent, very urgent, and followed by hospitalisation visits. The second aim was to investigate the role played by mother's educational level in the relationship between citizenship and ER utilisation. METHODS The cohort study included all healthy singleton live births in the years 2008-2009 and residing in the province of Reggio Emilia, followed for the first year of life in order to study their ER visits. The outcomes were the ER utilisation rate for all, non-urgent, very urgent, and followed by hospitalisation visits. The main explanatory variable was mother's citizenship. Other covariates were mother's educational level, maternal age, parity, and child gender. Multivariate analyses (negative binomial regression and zero inflated when appropriate) were performed. Adjusted utilisation Rate Ratios (RR) and their 95% Confidence Intervals (95% CI) were calculated. Trend for age in months by citizenship is depicted. RESULTS There were 3,191 children (36.4%) with at least one ER visit in the first year of life. Adjusted RR show a significantly greater risk of ER visit for immigrants than for Italians: (RR 1.51; 95% CI 1.39-1.63). Immigrants also had a higher risk of non-urgent visits (RR 1.72; 95% CI 1.48-2.00) and for visits followed by hospitalizations (RR 1.58; 95% CI 1.33-1.89). For very urgent visits, the immigrants had a slightly higher risk compared to Italians (RR 1.25; 95% CI 0.98-1.59).The risk of ER visits is higher in the first two months of life (RR(1st vs 3rd-12th) 2.08; 95% CI 1.93-2.24 and RR(2nd vs 3rd-12th) 1.45; 95% CI 1.33-1.58, respectively). Considering all visits, the ER utilisation rate was inversely related with maternal education only for Italians (low educational level 44.0 and high educational level 73.9 for 100 children; p value for trend test < 0.001). CONCLUSIONS Our study observed a higher use of ER services by immigrant children and, to a lesser extent, by children of less educated Italian mothers. In immigrants, the excess is mostly due to non-urgent visits and only slightly to high acute conditions.

Abstract
BACKGROUND Barker's fetal programming hypothesis suggests that disproportionate size at birth may have a lifelong impact on one's health. However, the literature on birth length is considerably more sparse compared with birthweight. We, therefore, examined the relationship between birth length and hospitalisation early in life among Japanese children. METHODS We used the nationwide Longitudinal Survey of Babies in 21st Century and restricted the study subjects to full-term singleton babies (n = 44,057). We estimated the effects of birth length and birthweight on the risk of hospitalisation using log linear regression models. We controlled for a set of neonatal and maternal factors. RESULTS Birth length was associated with the chance of hospitalisation due to all causes between 6 and 18 months of age. In addition, the association was stronger than that with birthweight. Adjusted risk ratios showed that the relationship between birth length and hospitalisation was U-shaped: 1.16 [95% confidence intervals, 1.08, 1.25] at 30-48 cm, 1 [Reference] at 49 cm, 1.13 [1.04, 1.22] at 50 cm, and 1.11 [1.02, 1.20] at 51-60 cm. Short babies with low or high weight, as well as long babies with low weight, seem to be at increased risk of hospitalisation. CONCLUSIONS We found a U-shaped relationship between birth length and risk of hospitalisation due to all causes during the period from 6 to 18 months.

Abstract
BACKGROUND An 8-year era of interrupted indigenous measles transmission in Bulgaria came to an end in April 2009 when a large epidemic occurred that would eventually claim 24,253 cases and 24 deaths; infants, children and young adults of the Roma community were disproportionally affected. Compared with Western Europe, case-fatality rate and proportion of medical complications were uncharacteristically high. METHODS To disentangle underlying drivers of the outbreak and reasons for these medical complications, we assembled a number of national ecologic variables as well as regional individual-level data for 206 measles cases, randomly selected from national medical records. We conducted a logit regression analysis of data from individuals with medical complications. RESULTS Ecologic socio-economic predictors were not associated with measles cases by region, although the proportion of medical complications differed considerably. Individual-level data from a region with high medical complications revealed that mother's education [odds ratio (OR) 0.79; 95% confidence interval (CI) 0.68-0.92], immunization status of the child (OR 0.28; 95% CI 0.08-0.94) and households declaring an income (OR 0.31; 95% CI 0.10-0.93) decreased the risk for developing severe medical complications such as pneumonia or encephalitis from a measles infection. DISCUSSION The extent of this outbreak with a high case-fatality rate and high proportion of medical complications calls for resolute public health action. We found vaccination and maternal education to be crucial conduits of curbing medical complications from measles infections. Ultimately, the goal is measles elimination in Europe by 2015, and these data hint at intervention entry points.

Children of low socioeconomic status show accelerated linear growth in early childhood; results from the Generation R Study. PLoS One 2012; 7:e37356.

Abstract
OBJECTIVES People of low socioeconomic status are shorter than those of high socioeconomic status. The first two years of life being critical for height development, we hypothesized that a low socioeconomic status is associated with a slower linear growth in early childhood. We studied maternal educational level (high, mid-high, mid-low, and low) as a measure of socioeconomic status and its association with repeatedly measured height in children aged 0-2 years, and also examined to what extent known determinants of postnatal growth contribute to this association. METHODS This study was based on data from 2972 mothers with a Dutch ethnicity, and their children participating in The Generation R Study, a population-based cohort study in Rotterdam, The Netherlands (participation rate 61%). All children were born between April 2002 and January 2006. Height was measured at 2 months (mid-90% range 1.0-3.9), 6 months (mid-90% range 5.6-11.4), 14 months (mid-90% range 13.7-17.9) and 25 months of age (mid-90% range 23.6-29.6). RESULTS At 2 months, children in the lowest educational subgroup were shorter than those in the highest (difference: -0.87 cm; 95% CI: -1.16, -0.58). Between 1 and 18 months, they grew faster than their counterparts. By 14 months, children in the lowest educational subgroup were taller than those in the highest (difference at 14 months: 0.40 cm; 95% CI: 0.08,0.72). Adjustment for other determinants of postnatal growth did not explain the taller height. On the contrary, the differences became even larger (difference at 14 months: 0.61 cm; 95% CI: 0.26,0.95; and at 25 months: 1.00 cm; 95% CI: 0.57,1.43) CONCLUSIONS Compared with children of high socioeconomic status, those of low socioeconomic status show an accelerated linear growth until the 18th month of life, leading to an overcompensation of their initial height deficit. The long-term consequences of these findings remain unclear and require further study.

Abstract
The purpose of this study was to examine socio-economic differences in the risk of hospitalisation among children aged 0-5 years in Denmark from 1985 to 2004. All children born between 1985 and 2004 (n=1,278,286) were followed for hospital admissions for infectious diseases from the 29th day of life until the children reached the age of 6 years or the end of 2004, whichever came first. Information on parental socio-economic position (education, labour market attachment and household income) was gathered through record linkage with administrative registries. Infections were grouped into upper respiratory, lower respiratory, gastrointestinal, ear and fever infections. The data were analysed using Cox regression. Children of parents on sick leave or early retirement had an increased risk of being hospitalised with an infection compared with children of employed parents. A clear inverse educational gradient in risk of offspring hospitalisation was also found. From 1985 to 2004 the inverse associations between parental education and risk of hospitalisation grew stronger, whereas the comparatively weaker association between household income and risk of offspring hospitalisation decreased in magnitude. The association between socio-economic status and hospitalisation was strongest for lower respiratory, gastrointestinal and ear infections. This study documented a socially patterned hospitalisation of pre-school children in Denmark. Future studies should investigate possible explanations for the increased risk among children from families with low socio-economic status.

Relationships between deprivation and duration of children's emergency admissions for breathing difficulty, feverish illness and diarrhoea in North West England: an analysis of hospital episode statistics. BMC Pediatr 2012; 12:22. [PMID: 22401311 PMCID: PMC3311147 DOI: 10.1186/1471-2431-12-22] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2011] [Accepted: 03/08/2012] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND In the United Kingdom there has been a long term pattern of increases in children's emergency admissions and a substantial increase in short stay unplanned admissions. The emergency admission rate (EAR) per thousand population for breathing difficulty, feverish illness and diarrhoea varies substantially between children living in different Primary Care Trusts (PCTs). However, there has been no examination of whether disadvantage is associated with short stay unplanned admissions at PCT-level. The aim of this study was to determine whether differences between emergency hospital admission rates for breathing difficulty, feverish illness and diarrhoea are associated with population-level measures of multiple deprivation and child well-being, and whether there is variation by length of stay and age. METHODS Analysis of hospital episode statistics and secondary analysis of Index of Multiple Deprivation (IMD) 2007 and Local Index of Child Well-being (CWI) 2009 in ten adjacent PCTs in North West England. The outcome measure for each PCT was the emergency admission rate to hospital for breathing difficulty, feverish illness and diarrhoea. RESULTS 23,496 children aged 0-14 were discharged following emergency admission for breathing difficulty, feverish illness and/or diarrhoea during 2006/07. The emergency admission rate ranged from 27.9 to 62.7 per thousand. There were no statistically significant relationships between shorter (0 to 3 day) hospitalisations and the IMD or domains of the CWI. The rate for hospitalisations of 4 or more days was associated with the IMD (Kendall's tau(b) = 0.64) and domains of the CWI: Environment (tau(b) = 0.60); Crime (tau(b) = 0.56); Material (tau(b) = 0.51); Education (tau(b) = 0.51); and Children in Need (tau(b) = 0.51). This pattern was also evident in children aged under 1 year, who had the highest emergency admission rates. There were wide variations between the proportions of children discharged on the day of admission at different hospitals. CONCLUSIONS Differences between rates of the more common shorter (0 to 3 day) hospitalisations were not explained by deprivation or well-being measured at PCT-level. Indices of multiple deprivation and child well-being were only associated with rates of children's emergency admission for breathing difficulty, feverish illness and diarrhoea for hospitalisations of 4 or more days.

Abstract
UNLABELLED Individuals exposed to high levels of stress might have an increased risk of infectious diseases. However, most of the previous studies have been conducted among adults. To examine the effect of childhood stress, we conducted a nationwide cohort study including all Danish children born from 1977 to 2004. Stressful life events (SFLE) included parental death, death of sibling or parental divorce. Outcome was defined as hospitalizations due to less severe (LSID) or severe infectious diseases (SID). Children were followed until the age of 15 years. The association between SFLE and risk of infections was evaluated through rate ratios (RR) comparing infectious disease incidence ratios in children with and without a history of SFLE. Overall, children exposed to SFLE were at 13% increased risk of LSID (RR = 1.13 (1.10-1.15)), but at no increased risk of SID hospitalization (RR = 1.05 (0.97-1.14)). Looking at the specific type of SFLE, parental divorce increased the risk of LSID (RR = 1.11 (1.09-1.14)) and SID hospitalization (1.11 (1.02-1.21)) by 11%, whereas no increased risk of LSID and SID hospitalization was observed following parental death. Finally, a 34% increased risk of LSID hospitalization (RR = 1.34 (1.23-1.45)) was observed following death of sibling, in contrast to no increased risk of SID hospitalization. CONCLUSION Childhood exposure to SFLE, especially parental divorce seems to increase the risk of infectious disease hospitalization. Although we cannot determine whether our observations are the result of a biological effect of stress, adoption of unhealthy behaviours or increased likelihood of hospitalization, our findings do have public health relevance as a considerable proportion of the children today will be exposed to SFLE, the majority to parental divorce.

Abstract
Inequalities in child health are of major concern to policymakers, public health specialists and clinicians. This review of studies within the context of the Generation R study illustrates that inequalities in population health, at least partly, originate in pregnancy and early childhood. The review shows inequalities with regard to the health of the pregnant mother, with regard to the growth of the fetus, with regard to birth outcomes, and with regard to health indicators in early childhood. These results are shown with regard to both biological/somatic outcomes, as well as with regard to psychosocial outcomes and healthy lifestyles. Both socioeconomic inequalities and ethnic inequalities in health are present. Although some inequalities can be explained by known determinants, research needs to be done to reach a full understanding of the pathways between social disadvantage and ill health in early childhood.

Abstract
OBJECTIVES To examine whether prenatal exposure to perfluorooctanesulfonate (PFOS) or perfluorooctanoate (PFOA) is associated with the occurrence of hospitalization for infectious diseases during early childhood. METHODS We randomly selected 1400 pregnant women and their offspring from the Danish National Birth Cohort (1996-2002) and measured PFOS and PFOA levels in maternal blood during early pregnancy. Hospitalizations for infection of the offspring were identified by the linkage to the National Hospital Discharge Register through 2008. RESULTS Hospitalizations due to infections were not associated with prenatal exposure to PFOA and PFOS. On the contrary, the relative risks of hospitalizations ranged from 0.71 to 0.84 for the three higher quartiles of maternal PFOA levels compared with the lowest, but no dose-response pattern was found. No clear pattern was observed when results were stratified by child's age at infection, with the exception of an inverse association between maternal PFC levels and risk of hospitalization during the child's first year of life. CONCLUSIONS These findings suggest that prenatal exposure to PFOA or PFOS is not associated with increased risk of infectious diseases leading to hospitalization in early childhood.

Abstract
The European Centre for Disease Prevention and Control was founded in response to newly emerging infections such as severe acute respiratory syndrome and avian influenza. However, Europe faces other communicable disease challenges that have proven to be remarkably resilient to public health interventions. We present examples of communicable diseases with inequitable distribution among those with poor educational attainment, low income, or other socioeconomic factors in every European country. Because these findings are incompatible with social justice and fairness, we examine strategic interventions targeting upstream causes of communicable disease transmission keeping in mind 10 indispensable public health functions essential to reach marginalized groups. These interventions have to be tailored to the socio-political context and rely on community-based decision-making and intersectorial collaboration.

Abstract
OBJECTIVE This study describes the burden and epidemiologic features of infectious disease hospitalizations among infants in the United States. METHODS Hospitalizations with an infectious disease listed as a primary diagnosis for infants (<1 year of age) in the United States during 2003 were examined by using the Kids' Inpatient Database. National estimates of infectious disease hospitalizations, hospitalization rates, and various hospital parameters were examined. RESULTS During 2003, an estimated 286,739 infectious disease hospitalizations occurred among infants in the United States and accounted for 42.8% of all infant hospitalizations. The national infectious disease hospitalization rate was 7010.8 hospitalizations per 100,000 live births, or approximately 1 infectious disease hospitalization for every 14 infants. The median length of stay was 3 days, and stays totaled >1 million hospital days for infants. Infectious disease hospitalization rates were highest among boys and nonwhite infants. The most commonly listed diagnoses among the infant infectious disease hospitalizations included lower respiratory tract infections (59.0%), kidney, urinary tract, and bladder infections (7.6%), upper respiratory tract infections (6.5%), and septicemia (6.5%). The median cost of an infectious disease hospitalization was $2235, with total annual hospital costs of approximately $690 million, among infants in the United States. CONCLUSIONS Infectious disease hospitalizations among infants account for substantial health care expenditures and hospital time in the United States, with respiratory disease hospitalizations constituting more than one half of all hospitalizations. Younger infants, boys, and nonwhite infants were at increased risk for infectious disease hospitalization. Measures to reduce racial disparities and the occurrence of respiratory tract infections should substantially decrease the infectious disease burden among infants.

Abstract
OBJECTIVE We anticipate a negative gradient between income and hospitalization, since income is positively associated with good health. In a previous cross-sectional study, we reported an unexpected pattern of association between poverty and hospitalization for 5-month-old infants in Quebec. This study re-examines the poverty-hospitalization relationship within a longitudinal population study of the same birth cohort aged 3.5 years. METHOD Life table analysis, multivariable proportional hazard regression, and multivariable logistic regression were performed on data from the first four waves of the Quebec Longitudinal Study of Child Development (QLSCD). Probabilities of hospitalization were estimated by poverty status. The hazard ratios (HR) (Cox-regression) for duration of poverty (frequency of insufficient income) and severity of poverty (combining frequency and level of income insufficiency) were estimated, controlling for predisposing, enabling, and need determinants of hospitalization. RESULTS At 3.5 years, 31% of children had been hospitalized at least once. Compared with children whose families had constantly sufficient income, children with intermittent poverty exhibited higher hospitalization risks (HR = 1.30; 95%CI = 1.04-1.64) while chronically poor children exhibited comparable hospitalization hazards (HR = 0.97; 95%CI = 0.73-1.27). Hospitalization risks for children in the severest poverty group resembled that of the non-poor group (HR = 0.99; 95%CI = 0.66-1.49), while children in less severely poor families were more likely to be hospitalized (HR = 1.26; 95%CI = 0.99-1.60). CONCLUSION Results suggest hospitalization barriers for children living in chronic and severe poverty. If these barriers exist in a universal health care system, they may originate with primary care service organization or hospital care referral procedures.
