Abstract: This study seeks to assess the epidemiological features of a GIS supported investigation of a cholera outbreak in Abeokuta. Abeokuta, the capital city of Ogun State, Southwestern Nigeria with an area of 1256 km2 and a population of 605, 451 people had an outbreak of cholera from 20th November, 2005 to 1st of January, 2006. The outbreak affected the Abeokuta North Local Government area where the municipal waterworks is located. Municipal water consumption was found to be associated with illness [McNemar’s Chi square (X2 = 20.5; p < 0.001) and Odds ratio 10]. The epidemiological surveillance data showed a total of one hundred and fifteen cases and 11 deaths with case fatality rate of 9.6%. Male specific and female specific case fatality rates were 11.9 and 7.1%, respectively. The age group of 15 years and above accounted for 68.3% of the cases and 90.9% of the deaths. Post epidemic environmental investigation showed progressive contamination along distribution points. Cholera is still a major cause of morbidity and mortality among youth and ageing population in Nigeria.[...] Read More.

Abstract: We sought to evaluate the extent to which self-rating of health, gender, and the co-occurrence of other health risk behaviors were related to suicidal behaviors among adolescents. Cross-sectional survey data of Colorado middle and high school students aged 12 to 18 years were analyzed using logistic regression. Main outcome variables were suicide ideation, suicide planning, and suicide attempt. Predictors included self-rated health, self-reported health behaviors, perception of body image, expression of sadness and hopelessness, self-reported sexual abuse, self-reported access to lethal weapon, and expression of school safety concerns. Adjusted results showed respondents with poor health rating had significantly higher odds of suicidal ideation (OR: 2.22), suicidal planning (OR: 1.35), and suicide attempt (OR: 2.23). Reporting of hopelessness was the most consistent predictor of suicidal behaviors with odds ratios ranging from 5.57 (for suicidal ideation) to 17.40 (for suicidal attempt). Factors associated with different adolescents’ suicidal behaviors were different for boys and girls. Findings suggest the need to consider gender differences as regards self assessment of health in order to improve the effectiveness of suicide interventions among adolescents.[...] Read More.

Abstract: Evidence mainly from high and middle income countries shows that community social capital is associated with positive health outcomes. The current policy interest in social capital stems from the anticipation that investing in it will enhance improvements in population health and some governments in high income countries have promoted initiatives to enhance its generation. However, there is a paucity of empirical evidence from low income countries on the utility of social capital for health outcomes. Therefore, the study objective was to assess the role of social capital in the use of health care services in Uganda, a low income country. The study sample included nine hundred and thirty six febrile children with complete data on place of treatment, caregiver social capital and socio-demographic variables; child demographic variables and household socioeconomic status were selected from the Iganga-Mayuge Health and Demographic Surveillance Site data base. The association for each dimension of social capital and use of a public health facility was explored using bivariate and multivariable regression models, controlling for potential confounding factors and other social capital variables at the individual caregiver and community levels. The study found that high levels of trust (OR 2.75, 1.50 to 5.02) and medium levels of informational support (OR 1.68, 1.12 to 2.50) were positively associated with the use of a public health facility. In contrast, high levels of reciprocity (OR 0.69, 0.49 to 0.97) were associated with non- use of a public health facility. This exploratory study shows an independent effect of community social capital on treatment choices made by child caregivers in a predominantly rural area of a low income country. This observation places social capital amongst the other contextual level factors that influence use of health care services in this setting. Such information can be used retrospectively or prospectively by health planners to enhance the response of communities to new policies and strategies.[...] Read More.

Abstract: The objective of the study was to identify the vaginal douching habits and the factors that would have a connection with this practice in women from Eskisehir Province in Turkey. This descriptive and cross-sectional study was conducted from 1 May to 30 June, 2005. In present study, any sampling technique was not used. The subjects were women belonging to the 15 - 49 age groups who were admitted to No. 2 Family Planning Center and Sultandere Primary Health Care Center. A survey containing such questions about the socio -demographic and reproductive characteristics was conducted on these women via a face-to-face interview method. Among the statistical tests, chi-square test and logistic regression analysis were utilized. A total number of 503 women with an average age of 33.18 ± 7.50 were attended at the health center. Vaginal douching was performed in 47.7% women and the most common the method was cleansing (66.6%) and post-intercourse (71.8%). The information about these methods was obtained mostly from their mothers (31.6%). In accordance with the results obtained from the study, the vaginal douching practice is a widespread conventional attitude among women and should be given the necessary importance. It was concluded that it is necessary to provide health education for women who state that they get information concerning the practice mostly from their mothers and this wrong attitude change needs to be corrected. Since vaginal lavage is directly linked with low education levels and the state of unemployment, it is resolved that such measures should be taken to increase the socio-economic levels of women. It is also concluded that special importance should be attached to the health education of the primary health care profession concerning the vaginal lavage.[...] Read More.

Abstract: Alabata is a community with no electricity and comprehensive topographic or administrative map. They also depend on a fuelled generating set to power the pumping machine for the UNICEF assisted borehole. The citizens often had to resort to an unsafe alternative water source for domestic purposes. In March 2006 an observational study trip through which data on sanitation, health and water sources were acquired was made to Alabata community. Coordinates of relevant facilities and water sampling points were taken and plotted in a Geographic Information System (using ArcView 3.2a GIS software). A base map for the study area was generated from satellite imagery (IKONOS). Sample points of water were overlaid on the base map that was produced from the satellite image. Water was collected from alternative water sources and analysed for bacteriological quality in the Microbiology laboratory. The bacteriological analysis of the different water sources with the exception of deep protected well with no recorded growth, showed that coliform count (> 1100 MPN/1000 ml), total Escherichia coli count (3-6 log cfu/ml), and total heterotrophic count (3-5 log cfu/ml). In all, the water samples generally exceeded the WHO and EPA standards of acceptable limit for drinking and domestic use.[...] Read More.

Abstract: This study gives the report of an epidemiological investigation of seven death cases in a police force headquarters by pesticide poisoning diagnosed by the decrease of the enzyme choline esterase activity. A case control study with an environmental description has been realized, permitting the establishment of temporarily dynamic relationships among the death cases. In Africa, there are many incidents of domestic or professional poisoning with a fatal ending for which, few data are available. The aetiological orientations are discussed in the African context and the difficulties to reach the analysis of toxicology in sub-Saharan Africa are underlined.[...] Read More.

Abstract: Our objective was to examine tracking patterns of body mass index (BMI) as well as their predictors between childhood and adolescence. A cohort of 452 Tunisian children aged 13 - 15 years was followed for 4 years (1999 - 2003). Tracking of BMI was defined as in individual maintaining a certain status or relative position (relative BMI quartile) overtime. After 4 years, almost 50% of the subjects had maintained their relative positions, but 25% had moved into a lower or higher quartile. The BMIs of thin and fat were more likely to track: 61.9 and 66.7% remained in the bottom and upper quartiles, respectively. Overweight children were 2.6 times as likely as all other children to become overweight adolescents. Individual’s initial BMIs, sex and socioeconomic status helped to predict tracking and change in BMI. Predictors of overweight tracking found in this study would be useful to select children at risk for preventive intervention.[...] Read More.

Abstract: In recent years, there has been a rise in applications of mathematical modelling in sexually transmitted infections. This paper outlines a new approach to mathematical modelling that tests intervention efforts on Chlamydia. The aim was to produce a simple model that can be used when new data comes to hand without the need to re-run the simulation. A simple model was developed to study the effects of interventions in lowering rates of Chlamydia in a high-risk population of 16 to 24 year olds. Parameters are informed by the best available data. The model was verified by running it backwards in time to see if it correctly ‘retrodicts’ rates of Chlamydia in the past. The model predicted that Chlamydia would disappear long-term if there were 45% condom use, annual check- ups and 23.5% successful contact tracing among the high-risk 16 – 24 year old age group. The model’s expressions can be applied readily to different populations of interest and to address specific questions, indicating that the model is a quick and easy tool to apply in public health policy making.[...] Read More.

Abstract: This study utilized data from Bangladesh Demographic and Health Survey 2004 to identify the determinants of knowledge about AIDS for women of urban and rural areas of Bangladesh, bi-variate and multivariate logistic regression methods were employed in analyzing data. This study found that a wider gap exists between urban and rural areas regarding knowledge about AIDS, where every 8 out of 10 urban women know about AIDS but almost half of the rural women still do not know about AIDS. Mass media play a major role for growing awareness about AIDS in both of these areas. In the urban area 61.6 percent women knew at least one correct way to avoid AIDS but rural women are in miserable condition because the corresponding figure for rural women was only 31.3% that means 37.7 and 67.7% among urban and rural women respectively still did not know how to avoid AIDS. Binary logistic regression method shows that education, occupation, ever use of contraception, currently using condom, permission to go to hospital/health center, mass media exposure, region of residence and wealth index significantly influence the knowledge about AIDS among rural women, whereas, in the urban areas except occupation and currently using condom all these remaining variables appear as the significant predictors of knowledge about AIDS.[...] Read More.
