[How are personal child health records completed? A multicentric evaluation study]

[Assessment of vaccination status and booster vaccinations in adolescents attending school in Libreville, Gabon]

Introduction

La vaccination chez l'adolescent est particulière et le statut vaccinal de ce dernier est peu connu. L'objectif de cette étude était d'apprécier ce statut vaccinal et d'identifier les facteurs associés à la compliance vaccinale chez les adolescents scolarisés à Libreville.

Méthodes

Une enquête observationnelle transversale descriptive a été réalisée chez les élèves des classes de 6^edu Lycée national Léon MBA de Libreville.

Résultats

Au total, 304 élèves ont été inclus dans l'étude. L'âge moyen des élèves était de 11,60±1,20 ans et le sexe ratio était de 0,6. Deux cent soixante-six enfants (87,5%) vivaient avec leur géniteur direct (père et/ou mère). Le nombre moyen d'enfants par famille était de 4. Le taux de couverture vaccinale était de 78,3%. Le nombre d'enfants par famille n'était pas associée à la couverture vaccinale des vaccins du PEV (p=0,088), par contre les enfants vivant avec au moins l'un des parents avaient une meilleure couverture vaccinale respectivement par les vaccins du PEV (p=0,025) et les vaccins hors PEV (p=0,035). Les facteurs évoqués par les parents pour expliquer la non-vaccination étaient le manque d'information (30,59%), l'oubli (24,67%) et le manque de moyens financiers (12,82%).

Conclusion

La couverture vaccinale des adolescents scolarisés à Libreville semble relativement proche des objectifs du PEV, mais elle reste associée à la situation familiale. D'autres campagnes de sensibilisation seraient utiles pour améliorer cette couverture vaccinale au Gabon.

[Records of growth and development data in the child health handbook]

OBJECTIVE

The aim was to analyse the input of growth and development data in the Child Health Handbook.

METHOD

This is a cross-sectional study conducted in Cuiabá, Brazil, on August 13, 2011, with the application of a questionnaire and direct observation of 950 handbooks. We included children under one year of age who resided in Cuiabá, accompanied by their mothers or guardians who were in possession of the handbook. Data were analyzed by calculating the prevalence ratio (PR) and Chi-Square test, with a significance level set at 5%. The project was approved by the Ethics Committee under Opinion No. 882/2010.

RESULTS

Of the analyzed handbooks, 95.4% of the development data and 79.6% of the data in the growth charts were incomplete or missing.

CONCLUSION

The low rate of growth and development data input in the handbooks reveals the need to create awareness among the population, health care professionals and managers on the importance of handbooks, and the need to invest in training and the empowerment of professionals in relation to its proper use.

A randomized pilot trial of growth hormone with anastrozole versus growth hormone alone, starting at the very end of puberty in adolescents with idiopathic short stature

BACKGROUND

When given during the course of puberty, anastrozole (A), an aromatase inhibitor, has been shown to increase the predicted adult height (PAH) of GH-deficient (GHD) boys treated with recombinant human growth hormone (rhGH). Our study questioned whether this treatment could retain some of its effects in non-GHD adolescent boys if started only at the very end of puberty, a time when rhGH treatment is denied to short adolescents who have almost reached their final height.

OBJECTIVE

To explore the effect on adult height of a combination of rhGH and A, compared with rhGH alone, at the end of puberty in boys with idiopatic short stature (ISS).

METHODS

A prospective randomized study comparing rhGH + A and rhGH was conducted in 24 healthy adolescent boys aged 15.2 ± 1.2 yrs with serum testosterone at adult levels and a faltering growth velocity <3.5 cm/yr leading to a predicted adult height (PAH) <2.5 SDS. Treatments were stopped when growth velocity became <10 mm in 6 months or when height was close to 170 cm. A historical group of ISS adolescents (N = 17) matched for puberty and growth was used for comparison.

RESULTS

IGF1 levels remained within normal limits in all treated patients. Mean treatment duration was 19 months in the rhGH + A group and 11.5 months in the rhGH group (P = 6.10(-4)). Adult height reached 168.4 ± 2.6 cm in the rhGH + A group and 164.2 ± 5.6 cm in the rhGH group (P < 0.02). Adult height was 160.1 ± 2.8 cm in the historical controls.

CONCLUSION

A combination of rhGH and A, started at the very end of puberty, seems to allow boys with ISS to reach a greater adult height than rhGH alone. Larger trials are needed to confirm this preliminary observation.

[Procedure used to follow-up a cohort of IVF children. Interests and limits of tools performed to longitudinal follow up for a monocentric cohort]

BACKGROUND

Follow-up of in vitro fertilization (IVF) children is recommended by the French health authorities. Follow-up procedures were set-up in a medically assisted reproduction unit at the Saint-Joseph Hospital in Marseille. The objective was to ensure effective follow-up. In this context, it is important to determinate weather the designated tools are appropriate for evaluating the desired developmental outcomes. This study was designed to describe the surveillance tool and to demonstrate its usefulness and limitations.

METHODS

The procedure was initiated in 2004. All existing data for every livebirth child were collected, including data concerning all IVF attempts, medical reports of pregnancy, and child health records. Parents were asked to complete questionnaires and provide their child's personal health records since birth. The quality of the data was evaluated using prenatal and postnatal analysis. The longitudinal anthropometric data of the health records were used to describe the percentiles of weights and heights from birth to 6 years in this population at age-specific reference intervals.

RESULTS

The follow-up concerned 2081 children born since 1995 with a response rate of 68,9%. A brief descriptive analysis was performed for the cohort and for a group of 1053 children aged five years and older, 225 representative personal health records were used to estimate quintiles for anthropometric data.

CONCLUSION

The procedure adopted for the follow-up of in vitro fertilization children meets the established qualitative health requirements. This method provides many benefits with no risk for the children. Data collection from personal health records enabled an exploitation of growth data by including the calculation of anthropometric percentiles in this IVF population. This report presents the first set of IVF child growth standards used as health indicator and health trend measurement.

A review of the personal health records in selected countries and Iran

Personal Health Record (PHR) enables patients to access their health information and improves care quality by supporting self-care. The purpose of this study is to provide a comparative analysis of the concept of PHRs in selected countries and Iran in order to investigate the gaps between Iran and more advanced countries in terms of PHRs. The study was carried out in 2008-2009 using a descriptive-comparative method in Australia, the United States, England and Iran. Data was gathered from articles, books, journals and reputed websites in English and Persian published between 1995 and September 2009. After collecting the data, both advantages and disadvantages of each of concepts were analyzed. In the three countries considered in the present study the concepts of PHR, extracted from the literature, are that; a)patient/person be recognized as the owner of PHR; b)information be disclosed only to those authorized by the patient; c) and that PHR is created upon request and consent of the individual involved. Before PHRs can be profitably used in the health administration of a (developing) country, the necessary knowledge, infrastructures, and rules need to be developed.

Qualidade do preenchimento da Caderneta de Saúde da Criança e fatores associados

A Caderneta de Saúde da Criança (CSC) é um documento imprescindível para a promoção da saúde infantil. Foi realizado um estudo transversal com amostra aleatória simples de crianças acompanhadas no Sistema Único de Saúde (SUS), visando analisar os fatores associados à qualidade do preenchimento da CSC. Foram realizadas entrevistas e verificação direta das cadernetas de 365 crianças das nove regionais de saúde de Belo Horizonte, Minas Gerais, Brasil. Foi criado um sistema de escore para classificar as CSC quanto à qualidade do seu preenchimento e relacioná-la às variáveis explicativas. O odds ratio foi calculado por regressão logística. O preenchimento dos vinte itens do escore variou de 3,1% (uso de ferruginoso) a 99,7% (data de nascimento). Os fatores associados aos piores escores foram: crianças > 12 meses de idade (OR = 1,77), mães < 6 anos de estudo (OR = 1,97), crianças não acompanhadas por médicos generalistas (OR = 3,18) e mães que não receberam explicações sobre a CSC na maternidade (OR = 1,77). Os resultados apontam a precária utilização da CSC, reforçando a necessidade de investimentos em capacitação dos profissionais e organização dos serviços para que ela cumpra seu papel na promoção da saúde infantil.

Apgar scores reported in personal child health records: validity for epidemiological studies?

AIM

In epidemiological studies on children, information in the neonatal period that might affect children's long-term health could be extracted from the personal child health record (PCHR), because the booklet exists in most countries. We aimed to assess, in individual children, the validity of Apgar scores reported in the PCHR using maternity medical records as the gold standard.

METHODS

In two French hospitals, 435 women who had a child in January 2006 were recruited and 90% filled in a postal questionnaire 6 weeks after delivery, copying neonatal information (including Apgar scores) from the PCHR. This information was compared with data independently recorded at birth by physicians in maternity medical records.

RESULTS

We found that the proportion of missing Apgar scores in the PCHR was higher when scores in the medical records were lower. Moreover, Apgar scores reported in the PCHR were overestimated when scores in the medical records were low. Using medical records as the gold standard, specificity for PCHR-reported 1-min Apgar score was 100% and sensitivity 33%. Similar trends were found for the 5-min score. This supports the hypothesis that information considered as 'socially sensitive' by physicians may be intentionally altered in PCHRs.

CONCLUSIONS

Apgar scores reported in PCHRs may not yield reliable information for epidemiological studies. When the PCHR is the only source of information for the neonatal period in an epidemiological study, it would be preferable to use a composite neonatal indicator rather than the Apgar score.

Perinatal factors reported by mothers: do they agree with medical records?

As perinatal events have been linked with diseases of later onset, epidemiological studies on child development and adult health require information on the perinatal period. When national neonatal registers do not exist, review of medical records may be impractical. However, neonatal information could be obtained by asking mothers to complete a postal questionnaire using data from the Personal Child Health Record (PCHR). We assessed agreement between medical records and mothers' reports for information on delivery and the newborn's condition at birth, based on the PCHR, a short time after delivery. Of 711 women giving birth in 3 French hospitals and invited to participate in the study, 580 (82%) completed a postal questionnaire 6 weeks after delivery, copying the data recorded in the PCHR when available. Information on pregnancy, delivery and the newborn's health at birth was independently extracted from medical records by physicians of the maternity departments. Agreement between medical records and maternal reports for a range of perinatal factors was assessed in 580 newborn-mother dyads using kappa coefficients. Agreement was excellent for first and second stages of delivery, gestational age, birth weight, birth size and head circumference (kappa coefficients 0.80-1.00) and good for hospitalization during pregnancy, but poor for Apgar scores. With this exception, mothers' reports appeared reliable when compared with medical records. As PCHRs exist in most developed countries, this approach could be used in epidemiological studies on child development to increase the reliability of mothers' reports of their newborn's condition at birth.

Vaccination and the risk of childhood acute leukaemia: the ESCALE study (SFCE)

BACKGROUND

In 2002, a poster alerted the French health authorities to the possibility that the risk of childhood leukaemia might be increased by hepatitis B vaccination. Elucidating the role of vaccination in the aetiology of childhood acute leukaemia (AL) was therefore included in the objectives of an ongoing national study.

METHODS

The ESCALE study was a French national population-based case-control study conducted in France in 2003 and 2004 in order to investigate the role of infectious, environmental and genetic factors in four childhood neoplastic diseases (leukaemia, lymphoma, neuroblastoma and brain tumour). The controls were randomly selected from the French population and age and gender frequency matched with the cases. A total of 776 cases of AL (91% of the eligible cases) and 1681 controls (71% of the eligible controls) were included. In a specific standardized telephone interview, which was the same for both the cases and controls, each mother was asked to read out her child's complete vaccination record.

RESULTS

No association between vaccination and the risk of childhood AL: acute lymphoblastic leukaemia or acute myeloblastic leukaemia was observed. No relationship between the risk of leukaemia and the type of vaccine, number of doses of each vaccine, total number of injections, total number of vaccine doses or number of early vaccinations was evidenced. No confounding factor was observed.

CONCLUSION

The study did not show any evidence of a role of vaccination in the aetiology of childhood leukaemia.
