Portugal making a difference with children and families: the GADIF model

Portugal is a culture grounded in strong traditions and family. Yet, social changes like women returning to the workforce and a decreas ed national birth rate are impacting the traditional family structure and care giving environments of children. Female employment has been increasing steadily in P ortugal over the last three decades (Galego & Pereira, 2006) and the total fert ility rate decreasing from 4.1 to 2.8 (INE, 2006). Furthermore, extended family me mbers, like grandparents, no longer reside close by to their children and grandc hildren as in the past, because of a changing labor market. Many of the younger gen eration are leaving their rural communities to flock to urban areas because o f job opportunities, leaving behind older relatives who would have otherwise par ticipated in the daily care of children. Given these social and economic changes, children are spending more time in out-of-home care with non-familial caregive rs. Yet, government regulations and guidelines in early care and educat ion (ECCE) and early intervention (EI) are only just emerging; it contin ues to be a work in progress.

Intra-familial physical violence among Mexican and Egyptian youth

OBJECTIVE: To determine the prevalence of experiencing intra-familial violence among Mexican and Egyptian youth and to describe its associated risk factors. METHODS: Data from questionnaires applied to 12,862 Mexican and 5,662 Egyptian youth, aged 10 to 19, who attended public schools were analyzed. Biviarate and logistic regression analysis were used to determine the relationship between socio-demographics, the experience of intra-familial violence and violence perpetration. RESULTS: The prevalence of having experienced intra-familial violence was comparable across the Mexican and Egyptian populations (14% and 17%, respectively). In Mexico, young men were more likely to have experienced such violence (OR=2.36) than women, whereas in Egypt, young women were at slightly greater risk than young men (OR=1.25). Older age, male gender and urban residence were independent correlates of experiencing intra-familial violence among Mexican youth. For Egyptian adolescents, in contrast, younger age, female gender and having non-married parents were independent correlates of victimization. Intra-familial violence victims were also more likely than non-victims to perpetrate violence (Mexico: OR=13.13; Egypt: OR=6.58). CONCLUSIONS: Mexican and Egyptian youth experienced intra-familial violence at a relatively low prevalence when compared with youth of other countries. A strong association was found between experiencing intra-familial violence and perpetrating violence.

Prevalência da violência contra a mulher por parceiro íntimo em regiões do Brasil

OBJETIVO: Analisar os resultados do WHO Multi-country Study on Women´s Health and Domestic Violence sobre a prevalência da violência contra mulheres por parceiros íntimos encontrada no Brasil. MÉTODOS: Estudo transversal integrante do WHO Multi-country Study on Women's Health and Domestic Violence against women, realizado em dez países, entre 2000-2003. Em todos os locais foi utilizado questionário estruturado padronizado, construído para o estudo. Para conhecer contrastes internos a cada país, a maior cidade e uma região rural foram investigadas, sempre que factível. Foi selecionada amostra representativa da cidade de São Paulo e de 15 municípios da Zona da Mata de Pernambuco constituída por mulheres de 15 a 49 anos de idade. Foram incluídas 940 mulheres de São Paulo e 1.188 de Pernambuco, que tiveram parceria afetivo-sexual alguma vez na vida. A violência foi classificada nos tipos psicológica, física e sexual, sendo analisadas suas sobreposições, recorrência dos episódios, gravidade e época de ocorrência. RESULTADOS: Mulheres de São Paulo e Pernambuco relataram, respectivamente, ao menos uma vez na vida: violência psicológica (N=383; 41,8% e N=580; 48,9%), física (266; 27,2% e 401; 33,7%); sexual (95; 10,1% e 170; 14,3%). Houve sobreposição dos tipos de violência, que parece associada às formas mais graves de violência. A maior taxa da forma exclusiva foi, para São Paulo e Pernambuco, a da violência psicológica (N=164; 17,5% e N=206; 17,3%) e a menor da violência sexual (N=2;0,2% e 12; 1,0%) CONCLUSÕES: Os resultados mostram a violência como um fenômeno de alta freqüência. Os achados reiteram estudos internacionais anteriores quanto à grande magnitude e superposições das violências por parceiro íntimo.

Fatores associados à violência por parceiro íntimo em mulheres brasileiras

OBJETIVO: Estimar a prevalência e os fatores associados à violência física e/ou sexual por parceiro íntimo em diferentes contextos socioculturais. MÉTODOS: Estudo transversal, participante do WHO Multi-country Study on Women's Health and Domestic Violence against women, com amostra representativa de mulheres no município de São Paulo e Zona da Mata de Pernambuco, região com normas mais tradicionais de gênero. Foram entrevistadas no domicílio 940 mulheres de São Paulo e 1.188 da Zona da Mata, entre 2000-1, com idade entre 15 a 49 anos que tiveram parceria afetivo-sexual com homens alguma vez na vida. Foram construídos três conjuntos de fatores, correspondentes a blocos hierarquicamente ordenados: características sociodemográficas, familiares e aspectos referentes à autonomia/submissão feminina. Utilizou-se regressão logística hierárquica na análise dos fatores associados à violência por parceiro íntimo em cada local. RESULTADOS: Encontrou-se prevalência de 28,9% em São Paulo (IC 95% 26,0;31,8) e 36,9% (IC 95% 34,1;39,6) na Zona da Mata. Escolaridade até oito anos, violência física conjugal entre os pais da mulher, abuso sexual na infância, cinco ou mais gestações e problemas com a bebida mostraram-se associados à violência por parceiro íntimo em ambos locais. Autonomia financeira da mulher, união informal, idade e consentimento na primeira relação sexual mostraram-se associadas a maiores taxas apenas na Zona da Mata. As características socioeconômicas associadas no primeiro bloco foram mediadas por outros fatores no modelo final. CONCLUSÕES: Os achados mostram a relativização dos fatores socioeconômicos diante de outros, em especial os representantes de atributos de gênero. Nas duas localidades estudadas foram encontradas diferenças socioculturais que se refletiram nos fatores associados.

Children and sand play: screening of potential harmful microorganisms in sandboxes, parks, and beaches

Sand serves as a reservoir for potentially pathogenic microorganisms. Children, a high-risk group, can acquire infections from sand in sandboxes, recreational areas, and beaches. This paper reviews the microbes in sands, with an emphasis on fungi. Recreational areas and beach sands have been found to harbor many types of fungi and microbes. A newly emerging group of fungi of concern include the black yeast-like fungi. After establishing that sand is a reservoir for fungi, clinical manifestations of fungal infections are described with an emphasis on ocular and ear infections. Overall, we recommend environmental studies to develop monitoring strategies for sand and studies to evaluate the link between fungi exposure in sand and human health impacts.

Sedentary behavior in Brazilian children and adolescents: a systematic review

ABSTRACT OBJECTIVE To describe the methodological characteristics of the studies selected and assess variables associated with sedentary behavior in Brazilian children and adolescents. METHODS For this systematic review, we searched four electronic databases: PubMed, Web of Knowledge, LILACS, SciELO. Also, electronic searches were applied in Google Scholar. A supplementary search was conducted in the references lists of the included articles and in non-indexed journals. We included observational studies with children and adolescents aged from three to 19 years developed in Brazil, presenting analyses of associations based on regression methods and published until September 30, 2014. RESULTS Of the 255 potential references retrieved by the searches, 49 met the inclusion criteria and composed the descriptive synthesis. In this set, we identified a great number of cross-sectional studies (n = 43; 88.0%) and high methodological variability on the types of sedentary behavior assessed, measurement tools and cut-off points used. The variables most often associated with sedentary behavior were “high levels of body weight” (in 15 out of 27 studies; 55.0%) and “lower level of physical activity” (in eight out of 16 studies; 50.0%). CONCLUSIONS The findings of this review raise the following demands to the Brazilian agenda of sedentary behavior research geared to children and adolescents: development of longitudinal studies, validation of measuring tools, establishment of risk cut-offs, measurement of sedentary behavior beyond screen time and use of objective measures in addition to questionnaires. In the articles available, the associations between sedentary behavior with “high levels of body weight” and “low levels of physical activity” were observed in different regions of Brazil.

Human toxocariasis: frequency of anti-Toxocara antibodies in children and adolescents from an outpatient clinic for lymphatic filariasis in Recife, Northeast Brazil

In a transversal study on a sample of 386 children and adolescents from an outpatient clinic for filariasis in Recife, Northeast Brazil, the frequency of anti-Toxocara antibodies and its relation to age, gender, number of peripheral eosinophils, Wuchereria bancrofti microfilariae and intestinal helminths was determined. The total anti-Toxocara IgG antibody frequency was 39.4%, by ELISA technique. The difference in frequency between males (40.1%) and females (37.6%) was not statistically significant. The 6 to 10-year-old subset presented the highest frequency of anti-Toxocara antibodies (60%), and within this age group there was a statistically significant male bias. There was also a significant association between the number of eosinophils and the presence of anti-Toxocara antibodies. Intestinal parasite frequency was 52.1%, but no association was found between this data and the presence of anti-Toxocara antibodies. In the present sample, 42.2% of the patients were Wuchereria bancrofti carriers, however, again this was not associated with the presence of anti-Toxocara antibodies. In conclusion, anti-Toxocara antibodies were highly prevalent in this sample. The present data show that there is no cross correlation between anti-Toxocara IgG antibody and the presence of intestinal helminths and filariasis.

Seroprevalence of hepatitis B and C infection markers among children and adolescents in the southern Brazilian region

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections account for a substantial proportion of liver diseases worldwide. The aim of this study was to determine the prevalence of HBV and HCV serological markers among children and adolescents and verify the epidemiology of the HBV infection over than a decade of the introduction of vaccination program. Serologic markers to HBsAg, total anti-HBc and anti-HCV had been tested in 393 samples. The seropositivity for HBsAg was 0.76% and for total anti-HBc was 1.02%. Copositivity between HBsAg and total anti-HBc was verified in 0.76% of the analyzed samples. There was no seropositivity for anti-HCV marker. The seroprevalence of HBV infection markers among children and adolescents in the southern Brazilian region is high compared to that reported in other countries. Preventive measures, such as educational activities in addition to the universal childhood HBV vaccination, should be initiated in order to reduce the morbimortality and the economic burden associated with the disease.

Fractures in Children and Adolescents with Spina Bifida: The Experience of a Portuguese Tertiary-Care Hospital

AIM: The morbidity associated with osteoporosis and fractures in children and adolescents with spina bifida highlights the importance of osteoporosis prevention and treatment in these patients. The aim of this study was to examine the occurrence and pattern of bone fractures in paediatric patients with spina bifida. METHOD: We reviewed the data of all paediatric patients with spina bifida who were treated in our centre between 1999 and 2008. RESULTS: One hundred and thirteen patients were included in the study (63 females, 50 males; mean age 10y 8mo, SD 4y 10mo, range 6mo-18y). The motor levels were thoracic in six, upper lumbar in 22, lower lumbar in 42, and sacral in 43 patients. Of the 113 patients, 58 (51.3%) had shunted hydrocephalus. Thirty-six (31.8%) were non-ambulatory (wheelchair-dependent [unable to self-propel wheelchair] n=3, wheelchair-independent [able to self-propel wheelchair] n=33), 13 were partial ambulators, 61 were full ambulators, and three were below the age of walking. Forty-five fractures were reported in 25 patients. The distal femur was the most common fracture site. Statistical analyses showed that patients with higher levels of involvement and in wheelchairs had a significantly increased risk of having a [corrected] fracture (p<0.001). Spontaneous fractures were the principal mechanism of injury, and an association was identified between fracture mechanism, type of ambulation, and lesion level: the fractures of patients with higher levels of motor functioning and those in wheelchairs were mainly pathological (p=0.01). We identified an association between risk of a second fracture, higher motor level lesion, and non-ambulation. There was an increased risk of having a second fracture after a previous spontaneous fracture (p=0.004). INTERPRETATION: Data in this study indicate a high prevalence of fractures in patients with spina bifida.
