Background

A socioeconomic gradient in childhood obesity is known to be present by the age of school entry in the UK. The origin of this gradient is unclear at present, but must lie in socioeconomic differences in habitual physical activity, sedentary behaviour, or dietary intake.

Aims

To test the hypothesis that habitual physical activity and/or sedentary behaviour are associated with socioeconomic status (SES) in young Scottish children.

Methods

Observational study of 339 children (mean age 4.2 years, SD 0.3) in which habitual physical activity and sedentary behaviour were measured by accelerometry over six days (study 1). In a second study, 39 pairs of children of distinctly different SES (mean age 5.6 years, SD 0.3) were tested for differences in habitual physical activity and sedentary behaviour by accelerometry over seven days.

Results

In study 1, SES was not a significant factor in explaining the amount of time spent in physical activity or sedentary behaviour once gender and month of measurement were taken into account. In study 2, there were no significant differences in time spent in physical activity or sedentary behaviour between affluent and deprived groups.

Conclusion

Results do not support the hypothesis that low SES in young Scottish children is associated with lower habitual physical activity or higher engagement in sedentary behaviour.  相似文献

Background:

Despite improvements in child health, malnutrition still remains one of the main public health challenges in Iran.

Objectives:

The aim of this study was to compare under nutrition among under-five children with regard to ethnicity in rural area in north Iran.

Patients and Methods:

In three cross-sectional studies 7575 subjects in three time-periods including 2339 children in 1998, 2749 in 2004, and 2487 in 2013, were evaluated. All under-five-children in 20 out of 118 villages were chosen by random sampling and assessed. Under nutrition was defined as underweight, stunting and wasting lower than -2 SD (Z < -2 SD).

Results:

Generally, stunting was declined 17.1% and underweight and wasting were increased 0.9% and 1%, respectively during 15 years (1998 - 2013). Underweight increased 0.5% in Fars-natives and 3.2% in Turkmans and it was decreased 0.9% in Sistanis. Statistical difference in Turkman children among the three stages of the study was significant (P = 0.001). Stunting has decreased 28.7% in Fars-natives and 35.1% in Sistanis, it was increased 9.3% in Turkman group. Statistical differences among three stages in inter-ethnic groups were significant (P = 0.001 for all). Compared the group with good economic status, the odds ratio was 1.831 in poor economic group (P = 0.001). The risk of under nutrition in Sistanis was 1.754 times more than in Fars-natives (P = 0.001).

Conclusions:

Under nutrition remains one of the main health problems in under-five-year children in north Iran being more common in Sistani children. Stunting in Sistani children deeply decreased while in Turkman children slightly increased during the 15-year period study. Poor economic status is a risk factor for under nutrition in this area.  相似文献

Objective

Clinical features of Iranian children with celiac disease (CD) are still unknown and there is scant information about atypical presentation of celiac disease from Iran. The aim of this study was to determine prevalence of CD in Iranian children presenting with functional abdominal pain (FAP).

Methods

In this cross-sectional study, 301 children affected by FAP were screened for CD by anti-tissue transglutaminase antibody (tTG IgA). IgA antibody was also measured to exclude IgA deficiency. The antibodies were measured by enzyme linked immunosorbent assay. Diagnosis of CD was confirmed by duodenal biopsy that was scored according to the Marsh classification in cases with abnormal titer of tTG antibody.

Findings

A total of 301 children (138 males, 163 females) with FAP were studied. Endoscopic duodenal biopsy was taken for patients with positive and borderline tTG test. Two out of 301 cases were IgA deficient and celiac disease was suspected for one of them based on histological findings. Four out of 299 patients with normal IgA had abnormal tTG titer; intermediate ranges (16–23 U/ml) were detected in 1 and positive ranges (≥24 U/ml) in 3 cases. CD was suggested in all patients with abnormal titer of tTG (1.33%) based on histological findings.

Conclusion

The prevalence of celiac disease in children with FAP is estimated 1.3% (nearly 2 times higher than in normal population) in Iran.  相似文献

Background:

The microflora hypothesis may be the underlying explanation for the growth of inflammatory disease. In addition to many known affecting factors, knowing the gut microbiota of healthy newborns can help to understand the gut immunity and modulate it.

Objectives:

This study examined the microbiota of healthy newborns from urban regions.

Patients and Methods:

We enrolled 128 full-term newborns, born at Seoul St. Mary and St. Paul hospital from January 2009 to February 2010. All 143 samples of feces were cultivated in six culture plates to determine the amounts of total bacteria, anaerobes, gram-positive bacteria, coliforms, lactobacilli, and bifidobacteria. The samples were evaluated with a bivariate correlation between coliforms and lactobacilli. Terminal restriction fragment length polymorphism (T-RFLP) analysis with HhaI and MspI and a clustering analysis were performed for determination of diversity.

Results:

Bacteria were cultured in 61.5% of feces in the following order: anaerobes, gram-positive bacteria, lactobacilli, coliform, and bifidobacteria. The growth of total bacteria and lactobacilli increased in feces defecated after 24 hours of birth (P < 0.001, P = 0.008) and anaerobes decreased (P = 0.003). A negative correlation between the growth of lactobacilli and coliforms was found (r = -463, P < 0.001).

Conclusions:

This study confirms that bacterial colonization of healthy newborns born in cities is non-sterile, but has early diversification and inter-individuality.  相似文献

OBJECTIVES

To assess the proportion of children meeting the new Canadian Sedentary Behaviour Guidelines for the Early Years (zero to four years of age) and to describe parental attitudes toward and barriers to reducing screen time.

METHODS:

Participants included 657 children zero to four years of age from the Kingston, Ontario, area. From May to September 2011, parents completed a questionnaire regarding their child’s screen time and their attitudes toward and barriers to reducing their child’s screen time.

RESULTS AND CONCLUSIONS:

Approximately 32% of children younger than two years of age engaged in no screen time and approximately 46% of children two to four years of age engaged in <1 h per day; thereby, meeting the recommendations of the new guidelines. Most parents believed that their child did not engage in excessive screen time. Physicians and other health professionals should inform parents of these new guidelines and provide strategies to help their children meet targets.  相似文献

Context:

To assess the efficacy of preoperative chemotherapy in Wilms’ tumor patients and explore its true value for specific subgroups.

Objectives:

In the presence of these controversies, a meta-analysis that examines the efficacy of preoperative chemotherapy in Wilms’ tumor patients and specific subgroups is needed to clarify these issues. The objective of this meta-analysis is to assess the efficacy of preoperative chemotherapy in Wilms’ tumor patients and explore its true value for specific subgroups.

Data Sources:

Computer-based systematic search with “preoperative chemotherapy”, “Neoadjuvant Therapy” and “Wilms’ tumor” as search terms till January 2013 was performed.

Study Selection:

No language restrictions were applied. Searches were limited to randomized clinical trials (RCTs) or retrospective studies in human participants under 18 years. A manual examination of references in selected articles was also performed.

Data Extraction:

Relative Risk (RR) and their 95% Confidence Interval (CI) for Tumor Shrinkage (TS), total Tumor Resection (TR), Event-Free Survival (EFS) and details of subgroup analysis were extracted. Meta-analysis was carried out with the help of the software STATA 11.0. Finally, four original Randomized Clinical Trials (RCTs) and 28 retrospective studies with 2375 patients were included.

Results:

For preoperative chemotherapy vs. up-front surgery (PC vs. SU) group, the pooled RR was 9.109 for TS (95% CI: 5.109 - 16.241; P < 0.001), 1.291 for TR (95% CI: 1.124 - 1.483; P < 0.001) and 1.101 for EFS (95% CI: 0.980 - 1.238; P = 0.106). For subgroup short course vs. long course (SC vs. LC), the pooled RR was 1.097 for TS (95% CI: 0.784 - 1.563; P = 0.587), 1.197 for TR (95% CI: 0.960 - 1.493; P = 0.110) and 1.006 for EFS (95% CI: 0.910 - 1.250; P = 0.430).

Conclusions:

Short course preoperative chemotherapy is as effective as long course and preoperative chemotherapy only benefits Wilms’ tumor patients in tumor shrinkage and resection but not event-free survival.  相似文献

Background:

Diabetes mellitus type 1 is the most common endocrine metabolic disorder occurring in childhood and adolescence due to the autoimmune destruction of pancreatic beta cells as a result of various environmental factors interacting with an underlying genetic predisposition. Diabetes is a risk factor for early onset atherosclerosis, and the high mortality rate seen in these patients is partially related to cardiovascular diseases.

Objectives:

This study was conducted to compare mean platelet volume as a marker of early atherosclerosis with aortic intima-media thickness in children with type 1 diabetes and to identify its correlation with known cardiovascular risk factors.

Patients and Methods:

The study included 27 patients between age range of 6 and 17 years that were diagnosed with type 1 diabetes and 30 healthy children of the same age range who did not have any chronic disease. In both groups, we used the color Doppler ultrasound to measure children’s aortic intima-media thickness and identify their mean platelet volumes.

Results:

There was no significant difference between the groups regarding gender distribution, age, High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL) cholesterol levels (P > 0.05). Also no significant difference could be documented between the patient and control groups regarding the aortic intima-media thickness and mean platelet volume (P > 0.05). However, there was a significant correlation between aortic intima-media thickness and mean platelet volume (r = 0.351; P < 0.05).

Conclusions:

In the present study, there was no evidence of early atherosclerosis in children with type 1 diabetes. However, mean platelet volume having a significant correlation with aortic intima-media thickness may be useful as an early marker of atherosclerosis.  相似文献

Objective

Cystic fibrosis and its distribution vary widely in different countries and/or ethnic groups. Common cystic fibrosis transmembrane conductance regulator (CFTR) mutations were reported from Iran, but the northern population was not or underrepresented in those studies. The aim of this study was to determine the frequency of common CFTR mutations in children from northern Iran.

Methods

Thirty unrelated Iranian cystic fibrosis patients aged less than 11 years and living in Mazandaran province (in Iran) were screened for 5 common CFTR gene mutations. deltaF508, N1303K, G542X, R347H and W1282X using Reverse Dot Blot method.

Findings

Only one mutation, DeltaF508, was found in 7 patients accounting for 21.7% (13/60) of alleles.

Conclusion

These findings can be used for planning future screening and appropriate genetic counseling programs in Iranian CF families.  相似文献

BACKGROUND:

In Turkey, 74.1% of children between three and six years of age develop dental caries.

OBJECTIVE:

To assess the depth of oral health and dental knowledge among paediatricians in Turkey, to determine their level of oral health education and to determine factors that were associated with higher knowledge scores.

METHODS:

A cross-sectional survey of demographics that assessed the participants’ knowledge of oral and dental health, attitudes regarding oral health during well-child visits and opinions regarding infant oral health care visits was conducted. The outcome variables were the proportions of paediatricians who adhered to good clinical practice guidelines, recommended dental visits for children younger than one year of age, and having a knowledge score >50%.

RESULTS:

The participant characteristics that were significantly associated with a greater mean number of correct answers were female sex, good clinical practice, confidence in detecting dental caries and the presence of a dentistry department in their hospital (P=0.001, P<0.001, P<0.001 and P=0.02, respectively). Only 13.9% of paediatricians referred children younger than one year of age to a dentist. After adjusting for the level of oral health education received during residency training, sex and having children, only the knowledge score was significantly associated with referring patients younger than one year of age to a dentist (P=0.01).

CONCLUSIONS:

Some paediatricians’ knowledge was found to be associated with practices that were in accordance with professional society recommendations. The lack of dental knowledge and training in residency limits the paediatricians’ role in promoting children’s oral health in daily practice.  相似文献

BACKGROUND:

Success in a task is not only related to skill, but it is also related to ‘self-efficacy’, or belief in one’s capability to perform that task. No tool currently exists to measure self-efficacy in clinical decision-making in general paediatrics.

OBJECTIVE:

To develop and provide validity evidence for the General Pediatrics-specific Self-Efficacy (GPedsSE) scale.

METHODS:

The five-item GPedsSE scale, developed using an expert panel, was matched to the New General Self-Efficacy (NGSE) scale’s structure for validity analysis purposes. Thirty-six postgraduate year 1 to postgraduate year 5 paediatric residents of the Montreal Children’s Hospital (Montreal, Quebec) completed the GPedsSE and NGSE scales, with items interspersed.

RESULTS:

The mean (± SD) GPedsSE score was 18.6±2.6 of 25. Total GPedsSE and NGSE scores were moderately correlated (r=0.54, P<0.005). On planned comparison, the GPedsSE score increased with training year (F[1.3]=6.62; P<0.001), while the NGSE score did not (F<0.37). Exploratory factor analysis showed two components, each aligning with a scale.

CONCLUSION:

The GPedsSE scale contextualizes an existing tool to general paediatrics, a novel concurrent validity approach.  相似文献

BACKGROUND:

Serum gentamicin concentrations (GSCs) are frequently obtained before and after gentamicin administration to newborns with, or at high risk for, sepsis.

OBJECTIVE:

To determine whether performing a peak GSC assay when the trough GSC is within the guidelines for care would add clinically relevant information for health care workers.

METHODS:

A retrospective review of the IWK Health Centre (Halifax, Nova Scotia) laboratory database for peak and trough GSC for infants <28 days after birth was performed.

RESULTS:

Of 5253 paired samples of trough and peak GSCs, 3001 (57%) had trough GSCs ≤2 μg/mL. Of these, only nine (0.3%) had a peak GSC >10 μg/mL.

CONCLUSIONS:

Performing a peak GSC measurement does not provide further clinically important data and increases patient morbidity and hospital costs.  相似文献

OBJECTIVE

To quantify visual estimation inaccuracies of infant emesis by parents and caregivers (P/Cs) and health care professionals (HCPs).

METHODS:

A single-blinded survey was performed in which P/Cs and HCPs visually estimated predetermined volumes of simulated emesis spilled on receiving blankets or pyjamas.

RESULTS:

HCPs’ estimations of volumes 1 and 3 were 150.4% and 145.1%, respectively, of the actual volumes, and their estimations of volumes 2 and 4 were 81.9% and 85.8%, respectively, of the actual volumes. This was, on average, significantly more accurate than the P/Cs’ estimations (P<0.001 to P=0.002), which ranged from 130.4% to 275.7% of the actual volumes.

CONCLUSION:

P/Cs and HCPs were, on average, highly inaccurate at visually estimating simulated emesis volume, an important consideration when making clinical judgments based on these estimations. In addition, HCPs now have an evidence-based tool to use in their practice when reassuring and counselling anxious parents.  相似文献

Background:

Tertiary pediatric hospitals usually provide excellent clinical services, but such centers have a lot to do for educational perfection.

Objectives:

This study was performed to address under-graduate educational deficits and find feasible solutions.

Patients and Methods:

This cross-sectional study was done in a target population of 77 sixth year undergraduate medical students (response rate = 78%) who spent their 3-month pediatric rotation in the Children’s Medical Center, the Pediatrics Center of Excellence in Tehran, Iran. The Dundee ready educational environment measure (DREEM) instrument was used for assessing educational environment of this subspecialized pediatric hospital.

Results:

Among 60 students who answered the questionnaires, 24 were male (40%). Participants’ age ranged from 23 to 24 years. The mean total score was 95.8 (48%). Comparison of scores based on students’ knowledge showed no significant difference. Problematic areas were learning, academic self-perception, and social self-perception.

Conclusions:

Having an accurate schedule to train general practitioner, using new teaching methods, and providing a non-stressful atmosphere were suggested solutions.  相似文献

Background:

Procalcitonin (PCT) kinetics is a good prognosis marker in infectious diseases, but few studies of children sepsis have been performed.

Objectives:

The aim of our study was to examine kinetics of procalcitonin, to evaluate its relationship with severity and to analyze its usefulness in the prediction of multiorgan dysfunction syndrome (MODS).

Patients and Methods:

Prospective observational study in an 8-bed pediatric intensive care unit of a university hospital. Sixty-two children aged 0-19 years with systemic inflammatory response syndrome or septic states. The degree of severity was evaluated according pediatric logistic organ dysfunction (PELOD) score. Blood tests to determine levels of PCT were taken if the patients had the criteria of systemic inflammatory response syndrome or sepsis. The serum to determine levels of PCT in control group has been taken from patients undergoing elective surgery.

Results:

Higher values of PCT were identified in patients with PELOD score 12 and more compared to those with PELOD < 12 (P = 0.016). Similarly, higher PCT values were found in patients who developed MODS in contrast to those without MODS (P = 0.011). According to ROC analysis cut-off value of 4.05 ng/mL was found to best discriminate patients with PELOD < 12 and PELOD ≥ 12 with AUC = 0.675 (P = 0.035). Effect of procalcitonin levels on mortality was not demonstrated.

Conclusions:

Levels of procalcitonin from day 1 to day 5 are related to the severity and multiorgan dysfunction syndrome in children.  相似文献

BACKGROUND:

Examining radiation dose in the paediatric population is particularly important due to the vulnerability of paediatric patients (increased radiosensitive tissues and postexposure life-years) and risk for future radiogenic malignancy.

OBJECTIVES:

To evaluate trends in paediatric computed tomography (CT) use and ionizing radiation exposure using population-based data from Nova Scotia.

METHODS:

A retrospective, population-based cohort study of CT use in patients <20 years of age, from January 1, 2004 to December 31, 2011, was performed in Nova Scotia. CT examination data were retrieved from a provincial imaging repository. Trends in CT use were described, and both annual and cumulative effective dose exposures were calculated.

RESULTS:

In total, 29,452 CT events, involving up to 22,867 individuals were retrieved. Overall annual paediatric CT examination rates remained static (range 17.4 to 18.8 per 1000 per year). However, use in children <10 years of age decreased by >50% (P<0.001); this was counterbalanced by a steady increase among 15- to 19-year-olds (P<0.0001). Overall, 15.4% of scanned patients underwent ≥2 examinations, of which 58 patients (1.6%) exceeded 50 mSv of exposure.

CONCLUSIONS:

Despite a static rate in CT imaging among the entire cohort, children <15 years of age and, particularly, those <10 years of age displayed marked reductions in CT use. This may reflect increased awareness of campaigns emphasizing judicious CT use, revised clinical practice guidelines and increased availability of alternative modalities. A small subgroup demonstrated high-dose exposure (>50 mSv), and rates in individuals >15 years of age steadily increased, suggesting further exposure reduction efforts are necessary.  相似文献

Background:

The World Health Organization (WHO) defines mental health as “a state of well-being in which every individual realizes own potential, can cope with the normal pressures of life, is able to work effectively, and can make a contribution to community”.

Objectives:

Mental Health Problems (MHP) is a great concern for all societies in terms of its burden and impact. This survey screened MHP and its impact in an Iranian urban population aged 6 - 12 years old, and explored its associated socio-familial factors.

Patients and Methods:

The survey was conducted in the elementary schools of Semnan, using random cluster sampling. Collection and analysis of data was performed using the parent version of the “Strengths and Difficulties Questionnaire (SDQ)” and survey commands of Stata-nine, taking into account cluster effect and population weights. Associations were assessed by fitting simple and multiple logistic regression models. P < 0.05 was considered significant.

Results:

With regard to the SDQ total score, 19.3% (95% CI: 8.6, 30.1) scored above the normal threshold (9.6% abnormal, 9.7% borderline). The frequency of problems ranged between 16.1% (peer problems) and 8.4% (emotional symptoms), and in all subscales boys were affected more than girls. The impact score was abnormal in 68.4% of all children, and was greater in girls than in boys. “A previously diagnosed mental health disorder” (OR = 11.11, 95% CI: 5.55, 25.00), “male gender” (OR = 1.43, 95% CI: 1.10, 1.87 and “less time spent with the child by father” (OR = 1.61, 95% CI: 1.20, 2.17) were significantly associated with an abnormal SDQ.

Conclusions:

The high rate of MHP in 6 - 12 year-old children and the lack of any significant correlation with their age, underpins the importance of early screening for MHP in schools, with particular focus on high risk groups.  相似文献

Objective:

Relatively little is known about the trace elements content of human milk from different countries. This has not been fully investigated especially among Iranian women. This study aimed to assess the concentration of Rubidium (Rb) as a poisonous trace element in transitional breast milk of lactating mothers living in Mashhad.

Methods:

Forty nursing mothers in early lactation 3 days to 15 days postpartum, free from any medical disorder and/or medication were randomly selected. We have applied Instrumental Neutron Activation Analysis (INAA) to assess the long-lived isotope trace element Rb in transitional milk of these economically moderate 18–39 year old Iranian women.

Findings:

The average concentration level of Rb was 32.176 ppm dry weight (min 8.660, max 107.210 ppm). No significant correlation was observed between Rb concentration and maternal weight and age (P=0.06, P=0.05 respectively) and newborns’ weight, age and sex (P=0.07, P=0.2, P=0.2 respectively).

Conclusion:

Although the Rubidium concentration found in this study is among the highest reported in the literature, it could not be compared to other studies because of differences in analytical performance, state of lactation, and unavailable reference ranges, so this finding needs further investigations.  相似文献

Objective

Pathogenesis of Henoch-Schönlein purpura (HSP) is not clearly defined. The present study was conducted to investigate the alterations in erythrocyte deformability and oxidative stress in HSP and to examine the possible relationship between erythrocyte deformability and organ involvement in this disease.

Methods

Plasma malondialdehyde (MDA) levels, total antioxidant status (TAS), erythrocyte deformability and aggregation were measured in 21 children with HSP at the disease onset and during the remission period in comparison with healthy subjects.

Findings

HSP patients at the active stage had significantly higher MDA and lower TAS levels (P<0.05). Erythrocyte deformability was decreased at the active-stage and increased again at the remission period of HSP (P<0.05). Erythrocyte deformability was significantly decreased at four different shear stresses in patients with gastrointestinal system or renal involvement; and decreased at six different shear stresses in patients with gastrointestinal system, and renal involvement compared to the patients without organ involvement (P<0.05). No significant difference was observed in aggregation parameters (P>0.05).

Conclusion

The present findings emphasize the association between impaired erythrocyte deformability and organ involvement in HSP.  相似文献

Background:

Tracheal intubation is extremely distressing, painful, and may influence heart rate and blood pressure. Sedatives, analgesics, and muscle relaxants are not commonly used for intubation in neonates.

Objectives:

This study aimed to evaluate the effects of lidocaine spray as a non-intravenous drug before neonatal intubation on blood pressure, heart rate, oxygen saturation and time of intubation.

Patients and Methods:

In a randomized, controlled study each neonate was randomly assigned to one of the two study groups by staffs who were not involved in the infant''s care. The allocation concealment was kept in an opaque sealed envelope, and the investigators, the patient care team, and the assessors were blinded to the treatment allocation. The selected setting was NICU unit of a teaching hospital in Ilam city, Iran and participants were 60 neonates with indication of tracheal intubation with gestational age > 30 weeks. Patients in the treatment group received lidocaine spray and the placebo group received spray of normal saline prior to intubation. Main outcome measurements were the mean rates of blood pressure, heart rate, oxygen saturation, intubation time and lidocaine side effects were measured before and after intubation.

Results:

Totally 60 newborns including 31 boys and 29 girls were entered into the study (drug group n = 30; placebo group n = 30). Boy/girl ratio in treatment and placebo groups were 1.3 and 0.88, respectively. Mean age ± SD of participants was 34.1 ± 24.8 hours (treatment: 35.3 ± 25.7; placebo: 32.9 ± 24.3; P < 0.0001). Mean weight ± SD of neonates was 2012.5 ± 969 g. Application of lidocaine spray caused a significant reduction of mean intubation time among treatment group compared with placebo group (treatment: 15.03 ± 2.2 seconds; placebo: 18.3 ± 2.3 seconds; P < 0.0001). Mean blood pressure, heart rate and oxygen saturation rate, among neonates in treatment group was reduced after intubation compared with their relevant figures before intubation; however, their differences were not statistically significant except for mean oxygen saturation rate that was reduced significantly in placebo group. No side effects were observed during study.

Conclusions:

Though the current study revealed some promising results in the application of lidocaine spray during neonatal intubation without any considerable side effects; however, the current investigation could only be considered as a pilot study for further attempts in different locations with higher sample sizes and in different situations.  相似文献
