Elimination of schistosomiasis requires multifactorial diagnostics: evidence from high- and low-prevalence areas in the Nile Delta, Egypt.

BACKGROUND: Schistosomiasis is one of the neglected tropical diseases (NTDs) selected for worldwide elimination in the near future. Egypt has made strong progress against its two endemic species of Schistosoma mansoni and S. haematobium. The former is prevalent in the Nile Delta with the latter dominating in the Nile south of Cairo. Innovative efforts are needed to reach the goal as further reduction of the prevalence has stalled due to ongoing transmission. In this study we aimed to explore the difference between low and high prevalence villages with regard to knowledge attitude and practice about schistosomiasis, utilization of health services, infection and transmission indices. METHODS: A hybrid cross-sectional longitudinal study was conducted with three annual follow-ups conducted during 1994-1996. We used a representative systematic random sampling technique investigating 993 individuals from the high prevalence village and 614 from the low prevalence village. Data were analyzed using SPSS, comparing proportions with the Chi square test and means with the Student t test, and ANOVA. RESULTS: Compliance of faecal sampling and chemotherapy was above 70% in both villages over the whole study period. Selective praziquantel treatment resulted in a significant reduction of prevalence and intensity of infection in both villages, dropping from 35.8% prevalence to 20.6%, in the low-prevalence village, and from 69.5 to 45.9% in the high-prevalence one. Intensity of infection at the base line was 30 eggs per gram (EPG) of stool in the low-prevalence village versus 105 EPG in the high-prevalence village. However, after the second round, reinfection rebounded by 22% in the high-prevalence village, while a slight improvement of the infection indices was demonstrated in the low-prevalence one. The level of knowledge was modest in both villages: people knew about self-protection and treatment, but not much about the role of human excreta for schistosomiasis transmission. While all participants maintained that using the water from the canals was inevitable, inhabitants in the high-prevalence village showed significantly lower scores reflecting higher water contact compared to the low-prevalence one. Many of them (67%) did not utilize the health centre at all compared to 26% of the people in the low-prevalence village. Interestingly, private clinics were seen as the primary source of health care by both villages, but more frequently so in the high-prevalence village (used by 87.2% of the inhabitants) compared to the low-prevalence one (59.8%). CONCLUSIONS: Even if chemotherapy works well as reflected by the observed downregulation of intensity of infection in both villages, reinfection continued due to difficulties to avoid water contact. Efforts must be made to make people understand the role of human excreta for transmission. There is also a need to make people better trust the medical services available.

Factors associated with hospitalization for type2 diabetic patients at a teaching hospital in saudi arabia.

UNLABELLED: Increasing prevalence of diabetes all over the world intensifies the demand for health care services, and particularly for inpatient care. The present study aims at identifying factors associated with hospitalization for patients with type 2 diabetes mellitus at a teaching hospital in Saudi Arabia. To achieve the objectives of the study, comparison was made between hospitalized and non-hospitalized type 2 diabetic patients using a retrospective case-control design. Four categories of factors namely, socio-demographic, outpatient clinic, clinical and quality indicators were investigated to elicit their relation with hospitalization among type 2 diabetes patients. Univariate analysis and stepwise multiple regression analysis were employed. Hospitalization was found to be independently associated with male gender, frequent visitors of outpatient clinics other than diabetes clinic, patients with nephropathy and patients with HbA1c >/= 7%. Limited number of cases and controls received the recommended ambulatory care for diabetes patients as evidenced by the marked low level of process of care indicators for diabetes patients. CONCLUSIONS AND RECOMMENDATIONS: Hospitalization was related to a limited number of factors many of which require better ambulatory care at outpatient clinics of the study hospital. It was recommended to continuously monitor the identified significant variables using the hospital electronic medical record system in order to target those patients at high risk for hospitalization.

Teacher's Knowledge, Attitudes and Management Practices about Diabetes Care in Riyadh's Schools.

The objective of this study was to assess diabetes-related knowledge, attitudes and management practices among school teachers in order to determine their diabetes training needs and preparedness to provide adequate care for students with diabetes. A cross sectional descriptive study was carried out among 177 school teachers in Boys and Girls primary and intermediate school compounds in Riyadh City. Data was collected using self-administered questionnaires during the period February-March 2007. The results showed that most of the school teachers had fair diabetes knowledge (78%), and unfavorable attitudes toward taking responsibility of diabetes education and care in schools. Recognizing normal, low and high blood sugar levels was the least known. The most frequent sources of information were booklets, brochures, mass media and own experience. A negative significant relationship was found between knowledge and attitude scores. Only 18.6% of teachers had got good total score of diabetes management practices for their diabetic students. The most frequent practices mentioned were trying to have competency in using glucometer, and allowing students to use restroom as needed. Developing an emergency action plan, and observing diabetic students all the school day were the least mentioned practices. Good diabetes managers were more knowledgeable and more expressing unfavorable attitudes. This study highlighted the need of diabetes education training courses especially designed to school teachers to promote adequate care and management of diabetes emergencies in schools.

Asthma education for school staff in Riyadh city: effectiveness of pamphlets as an educational tool.

UNLABELLED: Teachers and support staff are often called upon to manage asthma at school but may have little knowledge and understanding of the condition. The objectives of this study were to develop educational package (pamphlets) about asthma, and assess its effectiveness as an educational tool for schools' staff through evaluation of its impact on the staff's asthma-related knowledge, attitudes and management practices on their pupils. A pre-post experimental research design was used in Riyadh city with distribution of self-administered questionnaires and asthma package to 4 randomly selected girls schools compounds. Participants were school staff (n = 297) of primary, intermediate and secondary schools. Results showed that only 5.7% of the staff had received previous training in asthma education. Lack of knowledge and misconceptions about asthma medication were evident among a considerable proportion of the staff specifically for use of antibiotics, steroids, side effect of ventolin, and addicting effect of inhalers. At pretest, only 35% and 40.1% of the staff had good level of knowledge and management practices. At posttest, the corresponding percentages increased significantly to be 83.9% and 68.6% respectively. The mean total score of staff's asthma related-attitudes became more favorable towards asthma education after intervention, it increased significantly from 53.5 to be 55.0. Total posttest knowledge score was the only predictor of both staff attitudes and management practices constituting 9.1% and 10.2% of their variance. The great majority cited lack of training (92%), unavailability school policy (86.8%), and shortage of educational resources (88.3%) as barriers against asthma education and management in their schools. CONCLUSIONS: Most of school staff had poor to fair level of asthma knowledge and management practices. Such simple educational intervention using pamphlets and demonstration of inhaler use and peaked flow meter was significantly successful in enhancing staff's asthma-related knowledge, attitudes and management practices among their pupils. It is very important that training is directed to all staff as pre-service and in-service programs.

Weight management practices and their relationship to knowledge, perception and health status of Saudi females attending diet clinics in Riyadh city.

The objective of the study was to identify weight management (WM) practices among women attending diet clinics in Riyadh city, assess their impact on knowledge, perceptions, nutritional and health status and define some predictors for weight reduction among these women. The pretest-posttest research design was used. All female clients attending 8 diet clinics for the first visit within 8 months period and fulfilling the study inclusion criteria (212 out of 263) were included. The results show that out of 170 females who had previously tried to lose weight, only 32.4% reported success in reducing weight, meanwhile 61.7% reported weight regain. The mean total score of dietary practices, physical activity score, self efficacy and satisfaction of self-body image were improved significantly at posttest. Analysis of 24 h. dietary recall revealed that total energy and nutrients intake were significantly reduced at posttest. Dieting related problems increased significantly at posttest. Nutritional knowledge was at moderately fair level at both pretest and posttest; however it showed a significant improvement in the posttest. Perceived severity, perceived barriers and negative modeling effect were significantly decreased at the posttest. Over expectation for weight reduction was clearly evident as posttest body mass index (BMI) revealed a wide discrepancy between the expected and final weights. However, as compared to initial and final BMI, there was an increase in women who attained normal weight and a decrease in the percentage of obese and morbid obese women. All anthropometric indices, blood pressure, biochemical investigation showed significant improvement at posttest. Among the five WM modalities studied, moderate hypo-calorie plan diet modality was the longest (chi = 5.6 month) with the least weight loss (7.8%) and the minimum side effects. Both groups under very low calorie diet and protein diet had the highest weight reduction (13.2% &12.3%), at the same time both diets exhibited the highest number of side effects. The study recommends use of the primary approach for achieving weight loss through therapeutic life style change with banning those modalities accompanied with serious health complications.

Consumer-oriented evaluation of the service provided by the department of health education and information in Alexandria, Egypt.

BACKGROUND: Assessing consumers' satisfaction with health education services can help in monitoring the quality of provided service and understanding consumers' perceptions and utilization patterns of the service. MATERIALS AND METHODS: A cross-sectional descriptive study targeting consumers attending the health education sessions provided by Alexandria Department of Health Education and Information (DHEI) at different governmental health facilities and nongovernmental organizations was performed. A simple random sample of 400 participants was interviewed using an interview questionnaire assessing respondents' socioeconomic characteristics, health literacy, attitude toward health education services, and satisfaction with the health education service provided by the DHEI. RESULTS: Approximately 70% of the consumers' sample showed fair health literacy level. Most of the sample mentioned physicians a credible source of health knowledge followed by 58.8% who selected health education sessions as another trusted health information source. Overall, 90% of the sample was highly satisfied by the service overall. Behavior and skills of the service providers were the most satisfying aspects, whereas health education materials obtained the least satisfaction. Consumers' educational level and healthcare affordability proved to have a significant positive influence on their satisfaction (ß=0.307 and 0.191, respectively) whereas occupation and family income showed a significant negative influence (P<0.001). CONCLUSION: The service provided by Alexandria DHEI is highly satisfying to its target audience mainly in terms of providers and accessibility. Enhancing the technical skills of the department staff through training is highly recommended. The department is also recommended to advocate for the credibility of social workers and health visitors as health educators among the community.

Impact evaluation of nutrition education intervention for an elementary school in riyadh city.

A nutritional education intervention (NEI) was conducted to assess its impact and suitability for the 5th and 6th graders at a governmental girls' elementary school in Riyadh city. The study design was a randomized posttest only control group. The results revealed that the mean knowledge score of the first posttest for intervention classes was higher than that of their controls (F=91.147, p<0.001). This score increased markedly among all classes at the post-posttest. The mean self-efficacy (SE) score of the control class of 5th graders and intervention class of 6th graders at posttest were much lower than that of their comparable classes and both classes showed significant increase of SE in the post-posttest (paired t=2.819 and 4.561, p<0.01 and p<0.001 respectively). The mean practice score of the posttest was lower among intervention class of the 5th graders than their control, but both means were much higher than that of both classes of the 6th graders (F=6.856, p<0.001). Only control class of the 6th graders showed increased mean practice score at the post-posttest. Stepwise linear regression models reveal that exposure to NEI session was a major predictor of students knowledge at posttest (R(2)=.345). Knowledge score was a predictor of students' dietary SE and practices scores at posttest (R(2)=.041 & .136). Self efficacy was a predictor of students' dietary practices at posttest and post-posttest (R(2)=.107 & .162) as well as lower body mass index (R(2)=.048). The study recommends the replication of such a program among diverse population of school students to have more improvement in students' dietary knowledge, SE and practices.
