Fluoride in drinking water plays a vital role in dental health. Due to excessive fluoride in water, enamel loses its luster. At lower concentration, it guards our teeth against cavities but at higher concentrations imparts fluorosis in varying concentrations. Excess fluoride in drinking water is reported from more than 35 countries around the globe with India and China. In countries like India, the severe contamination of drinking water with excess fluoride acquired the dimensions of a social economic rather than a public health problem triggering defluoridation research.

Background. Anemia is a widely spread public health problem and affects individuals at all levels. However, there is a considerable regional variation in its distribution. Objective. Thus, this study aimed to assess and model the determinants of prevalence of anemia among children aged 6–59 months in Ethiopia. Data. Cross-sectional data from Ethiopian Demographic and Health Survey was used for the analysis. It was implemented by the Central Statistical Agency from 27 December 2010 through June 2011 and the sampling technique employed was multistage. Method. The statistical models that suit the hierarchical data such as variance components model, random intercept model, and random coefficients model were used to analyze the data. Likelihood and Bayesian approaches were used to estimate both fixed effects and random effects in multilevel analysis. Result. This study revealed that the prevalence of anemia among children aged between 6 and 59 months in the country was around 42.8%. The multilevel binary logistic regression analysis was performed to investigate the variation of predictor variables of the prevalence of anemia among children aged between 6 and 59 months. Accordingly, it has been identified that the number of children under five in the household, wealth index, age of children, mothers’ current working status, education level, given iron pills, size of child at birth, and source of drinking water have a significant effect on prevalence of anemia. It is found that variances related to the random term were statistically significant implying that there is variation in prevalence of anemia across regions. From the methodological aspect, it was found that random intercept model is better compared to the other two models in fitting the data well. Bayesian analysis gave consistent estimates with the respective multilevel models and additional solutions as posterior distribution of the parameters. Conclusion. The current study confirmed that prevalence of anemia among children aged 6–59 months in Ethiopia was severe public health problem, where 42.8% of them are anemic. Thus, stakeholders should pay attention to all significant factors mentioned in the analysis of this study but wealth index/improving household income and availability of pure drinking water are the most influential factors that should be improved anyway.

The aim of this study was to determine the prevalence and severity of dental fluorosis among 12-15-year-old students from João Pessoa, PB, Brazil before starting a program of artificial fluoridation of drinking water. The use of fluoridated dentifrice was also surveyed. A sample of 1,402 students was randomly selected. However, 31 students refused to participate and 257 were not permanent residents in João Pessoa, thus leaving a final sample of 1,114 students. Clinical exams were carried out by two calibrated dentists (Kappa = 0.78) under natural indirect light. Upper and lower front teeth were cleaned with gauze and dried, and then examined using the TF index for fluorosis. A questionnaire on dentifrice ingestion and oral hygiene habits was applied to the students. The results revealed that fluorosis prevalence in this age group was higher than expected (29.2%). Most fluorosis cases were TF = 1 (66.8%), and the most severe cases were TF = 4 (2.2%). The majority of the students reported that they had been using fluoridated dentifrices since childhood; 95% of the participants preferred brands with a 1,500 ppm F concentration, and 40% remembered that they usually ingested or still ingest dentifrice during brushing. It was concluded that dental fluorosis prevalence among students in João Pessoa is higher than expected for an area with non-fluoridated water. However, although most students use fluoridated dentifrices, and almost half ingest slurry while brushing, the majority of cases had little aesthetic relevance from the professionals' point of view, thus suggesting that fluorosis is not a public health problem in the locality.

Zusammenfassung. Kindesmisshandlung stellt einen bedeutenden Risikofaktor für die Entwicklung dar. Einzelne Formen von Kindesmisshandlung treten häufig nicht isoliert auf, sondern das gemeinsame Auftreten verschiedener Formen von Kindesmisshandlung stellt eher die Regel als die Ausnahme dar. Neben den langfristigen und vielfältigen individuellen Folgen führt Kindesmisshandlung jährlich zu einer hohen gesamtgesellschaftlichen Belastung. Die WHO hat Kindesmisshandlung als großes Public Health Problem identifiziert und die Vereinten Nationen haben den Kampf gegen Kindesmisshandlung zum Ziel in ihrer Agenda für nachhaltige Entwicklung gemacht. In dem vorliegenden Beitrag werden die Häufigkeit sowie das gemeinsame Auftreten unterschiedlicher Formen von Kindesmisshandlung sowie deren Assoziation mit psychischen und somatischen Folgen auf Basis einer bevölkerungsrepräsentativen Stichprobe untersucht und dargestellt. Die Ergebnisse verdeutlichen den Zusammenhang zwischen der Kumulation verschiedener Formen von Misshandlung und negativen Folgen für die Betroffenen. So ist das Risiko für negative Konsequenzen beim Erleben von vier oder mehr Formen von Misshandlung um das bis zu 10-fache erhöht. Viel zu selten werden die kumulativen Effekte von mehreren Belastungen berücksichtigt. Gerade weil die Wirkweisen über die Misshandlung, die Gesundheit beeinflusst, zunehmend gut untersucht sind, muss dieses Wissen im Gesundheitswesen stärker bei der Konzeption von Präventions- und Interventionsmaßnahmen berücksichtigt werden.

Dengue hemorrhagic fever (DHF) is a contagious disease caused by the dengue virus and is transmitted by the mosquito Aedes aegypti (Aa.aegypti). The population is still a public health problem that increases the number of sufferers and also widespread, with population and education. This study aims to reveal the spatial pattern and distribution of Dengue Hemorrhagic Fever (DHF) with the spatial pattern and the spread of Dengue Hemorrhagic Fever (DHF) can result in different locations of these allegations. From the map that can be used for the prevention of Dengue Hemorrhagic Fever (DBD) in Bandar Lampung City. This study aims to reveal the spatial pattern and distribution of Dengue Hemorrhagic Fever (DHF) with the descriptive method and spatial pattern of Dengue Hemorrhagic Fever (DHF) can result in different locations of these allegations.
