Hygienic Conditions (hygienic + condition)
Selected AbstractsScreening for faecal contamination in primary schools in Crete, GreeceCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 2 2009A. Kyriacou Abstract Background Hygienic conditions in primary schools are a major concern for both governmental organizations and families. Particularly, the occurrence of faecal indicators on children's hands and various school surfaces has been associated with increased risk of diarrhoeal diseases. The presence of faecal streptococci on environmental surfaces and children's hands and the possible correlation with socio-economic factors were examined. Methods Overall, 1956 samples from hands and 1470 samples from surfaces were collected from 20 primary schools in Heraklion, Crete, Greece. Results Faecal streptococci were found at 52.9% of children's hands and at 16.7% of other surfaces. Children, who had parents with the highest education level (>12 years), had the lowest percentage (48.8%) of faecal contamination on their hands. Furthermore, boys exhibited higher levels of hands contamination compared with girls. Among the environmental surfaces examined, the school canteen reception was the most contaminated area. Conclusion High faecal contamination was detected in primary schools in the examined region. Children's hands were highly infected (52.9%), while boys exhibited higher levels of contamination. The educational level of parents correlated well with the contamination of children's hands. [source] Seroprevalence of Helicobacter pylori Infection Among Schoolchildren and Teachers in TaiwanHELICOBACTER, Issue 3 2007Ding-Bang Lin Abstract Background:,Helicobacter pylori are associated with chronic antral gastritis that is related to duodenal ulcer, gastric ulcer, and probably gastric adenocarcinoma. Infection of H. pylori during childhood is considered an important risk factor for gastric carcinoma in adult life. Materials and Methods:, To examine the epidemiologic characteristics of H. pylori infection among schoolchildren in central Taiwan, a community-based survey was carried out using stratified sampling in 10 elementary schools and three junior high schools including students and theirs teachers. Serum specimens of 1950 healthy schoolchildren (aged 9,15 years old) and 253 teachers who were randomly sampled were screened for the H. pylori antibodies by enzyme-linked immunosorbent assay. Statistical analysis was performed by using the spss for Windows statistical software system. Results:, A total of 332 subjects were H. pylori antibodies positive, giving an overall prevalence of 15.1%. The age-specific seropositive rates were 11.0% in 9,12 years age group, 12.3% in 13,15 years age group, and 45.1% in the teacher group. The older the age, the higher the seroprevalence (OR = 11.53; 95% CI = 6.73,19.74; p < .001 for children vs. teachers). There was no difference in the seroprevalence of H. pylori infection by gender, ethnicity, geographical area, socioeconomic level, parental education, sibship size, family members, and source of drinking water. Conclusion:, The teachers had a much higher prevalence of H. pylori antibodies. The finding suggests that these teachers (adults) might be infected in their early childhood and implies that the poor environmental and hygienic conditions might be responsible for it. It seemed that poor water supply system, sewage disposal, and other environmental hygiene in adult might play some roles in H. pylori infection in Taiwan (before early 1980s). [source] Effect of caregiver feeding behaviours on child nutritional status in rural GhanaINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 3 2007Christina A. Nti Abstract A six-month observational study involving 100 mothers with infants between the ages of 6 and 12 months was conducted in the Manya Krobo district of Ghana. The objective was to assess the role of caregiver feeding behaviours on child nutritional status using a modified positive deviance approach. Each child was in the study for 6 months, during which they were observed at home once a month. On each visit, data were collected on the child anthropometry, child meal frequency, diet diversity, responsiveness of caregiver during feeding, child's appetite and feeding atmosphere as well as caregiver hygienic practices related to feeding. Using weight-for-age (WAZ) and length-for-age (LAZ) scores, the children were classified as positive or negative deviant children. The study revealed significant differences between the two groups of children in terms of caregiver feeding behaviours. Positive deviant children had significantly higher meal frequencies (3.1 ± 0.4 vs. 2.4 ± 0.6, P = 0.001), diet diversity scores (6.3 ± 0.6 vs. 3.7 ± 1.1, P = 0.001), were fed under better hygienic conditions (7.2 ± 0.9 vs. 4.2 ± 1.1, P = 0.001) and were much more interested in food during feeding (85.8% vs. 59.3%). Caregiver responsiveness during feeding was also significantly higher among the positive deviant group (6.5 ± 0.8 vs. 4.5 ± 0.9, P = 0.001). This study has demonstrated the tremendous effect of caregiver feeding behaviours on child nutritional outcomes and provides a scientific basis for introducing care during feeding as a component of intervention to improve child nutritional status in Ghana. [source] Seroepidemiology of hepatitis A, B, C, and E viruses infection among preschool children in TaiwanJOURNAL OF MEDICAL VIROLOGY, Issue 1 2006Jye-Bin Lin Abstract Taiwan was a hyperendemic area for hepatitis A and B viruses (HAV and HBV) infection before late 1980s. To study the seroprevalence of hepatitis A, B, C, and E viruses (HCV and HEV) infection among preschool children in Taiwan, a community-based survey was carried out in 54 kindergartens in 10 urban areas, 10 rural areas, and 2 aboriginal areas randomly selected through stratified sampling. Serum specimens of 2,538 preschool children were screened for the hepatitis A, C, and E antibodies by a commercially available enzyme immunoassay and for HBV markers by radioimmunoassay methods. The multivariate-adjusted odd ratios (OR) with their 95% confidence intervals (CI) were estimated through the multiple logistic regression analysis. Females had a statistically significantly higher HAV seroprevalence than males. The seroprevalence of HCV infection increased significantly with age. The larger the sibship size, the higher the seroprevalence of HBV infection. Aboriginal children had a significantly higher seroprevalence of HBV and HEV infection and lower seroprevalence of HCV infection than non-aboriginal children. A significantly higher seroprevalence of HBV infection was found in rural children than urban children. There was no significant association between serostatus of HAV and HEV infection and between serostatus of HBV and HCV infection among preschool children in Taiwan. The poor environmental and hygienic conditions in the aboriginal areas might play a role in infection with HBV and HEV. J. Med. Virol. 78:18,23, 2006. © 2005 Wiley-Liss, inc. [source] Risk of hepatitis A infection following travelJOURNAL OF VIRAL HEPATITIS, Issue 6 2002M. Ciccozzi summary.,Travel to endemic areas is one of the most frequently reported risk factors for infection with the hepatitis A virus (HAV). We evaluated the association between HAV infection and travel, by area of destination. We conducted a case,control study on all cases of HAV infection reported to the Italian National Surveillance System for Acute Viral Hepatitis in the period 1996,2000. The study population consisted of 9695 persons with HAV infection (cases) and 2590 with HBV infection (controls). The risk of acquiring HAV was highest for travel to Asia, Africa and Latin America [Odds Ratio=9.30 (95%CI=6.71,12.9)]; a three-fold statistically significant excess of risk was found for travel to southern Italy (OR=3.03) and to the Mediterranean Area and Eastern Europe (OR=3.15). Travel was implicated in 28% of the cases of HAV infection. When stratifying the analysis by area of residence (northern and central Italy vs southern Italy and the Islands), the above-mentioned risks were confirmed only for those residing in northern and central Italy, with no significant risk for those residing in southern Italy and the Islands. Travel to areas endemic for HAV infection constitutes a considerable risk. Our results highlight the importance of developing health policies for improving environmental and hygienic conditions, as well as the prevention of certain eating habits. Vaccination before travelling to a medium or high endemic area could be a safe and effective means of preventing travel-related HAV infection. [source] Vertical transmission of HIV-1 infection and dilemma of infant feedingACTA PAEDIATRICA, Issue 9 2003A Ehrnst The problem of giving proper recommendations on early feeding of infants of HIV-1-positive mothers in countries with deficient hygienic conditions is discussed. Even in exclusive breastfeeding, which is associated with a lower risk of HIV transmission than when supplements are given, the risk that the infant will acquire HIV-1 has to be balanced against the risk of formula feeding. Furthermore, it also has to be stressed that exclusive breastfeeding is a rarity in many poor countries. Conclusion: The dilemma of recommending appropriate early feeding to HIV-1-positive mothers will persist until further studies of the type performed by the Coutsoudis group in South Africa have been performed.
