Social and lifestyle factors associated with diabetes in the adult Bahraini population.

This paper aimed to assess the prevalence of known diabetes among Bahraini adults, and to determine associated social and lifestyle factors. A community-based survey was carried out on 514 adults aged 30-79 years. The overall prevalence of known diabetes was 9%. Using multivariate analysis, the risk of diabetes was found to be higher among older (50-79 years), female, illiterate, currently married, non-smoking people, those who did not walk regularly, overweight and obese people (BMI > or = 25), those who had a history of hypertension and those who consumed fresh vegetables more than 3 times a week. However, only obesity was found to be significantly associated with diabetes (OR = 1.83, CI 1.48-4.15).

Relationship between body composition and blood pressure in Bahraini adolescents.

The objective of the present study was to examine the relationship between body composition and blood pressure (BP) in Bahraini adolescents. A sample of 504 Bahraini schoolchildren aged 12-17 years (249 boys and 255 girls) was selected using a multi-stage stratified sampling procedure. BP measurements were performed on the students. Anthropometric data including weight, height, waist circumference (WC), hip circumference, and triceps, subscapular and medial calf skinfold thicknesses were also collected. BMI, percentage body fat, waist:hip (WHR), and subscapular:triceps skinfold ratio were calculated. Mean systolic BP and mean diastolic BP were higher in males than in females. Weight and height in boys and weight only in girls were significantly associated with systolic BP independent of age or percentage fat. Nearly 14 % of the adolescents were classified as having high BP. BMI and percentage body fat were significantly and positively associated with the risk of having high BP in the boys and girls. Adolescents with high WHR or WC, as indicators for central obesity, tended to have higher BP values. The results from the present study indicate that obesity influences the BP of Bahraini adolescents and that simple anthropometric measurements such as WHR and WC are useful in identifying children at risk of developing high BP. These findings together with the known tracking of BP from adolescence into adulthood underline the importance of establishing intervention programmes in order to prevent the development of childhood and adolescent obesity.

Five cases of bacterial endocarditis after furunculosis and the ongoing saga of community-acquired methicillin-resistant Staphylococcus aureus infections.

Bacterial endocarditis secondary to Panton-Valentine leukocidin producing community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections is rare. We report 5 previously healthy patients who presented with endocarditis after developing furunculosis due to CA-MRSA. A retrospective chart review of all patients with MRSA positive blood cultures was conducted over a 12-month period. Patients with multiple positive blood cultures within 72 h of admission and who had no risk factors for MRSA acquisition were included. Modified Duke's criteria were used to define bacterial endocarditis. PCR detection of Panton-Valentine leukocidin (PVL) genes as well as SCCmec typing was performed. In addition, strain typing of MRSA isolates was performed utilizing pulsed-field gel electrophoresis. Five out of a total of 193 patients had features consistent with CA-MRSA infections and met modified Duke's criteria for bacterial endocarditis. Blood culture isolates were found to be PVL gene positive and carried the type IV SCCmec element. PFGE confirmed that skin isolate was identical to the isolate cultured from his blood. Bacterial endocarditis in patients with CA-MRSA furunculosis is an emerging entity. In areas where CA-MRSA skin infections are prevalent, inappropriate initial antibiotics remain a major problem and may result in significant morbidity.

Student-led tutorials in problem-based learning: educational outcomes and students' perceptions.

The aim of this study was to examine the effectiveness of using students as tutors in a problem-based learning (PBL) medical curriculum. Ninety-one third-year medical students were divided into ten tutorial groups. The groups were randomly allocated into student-led tutorials (SLT) (five groups, n = 44 students) and faculty-led tutorials (FLT) (five groups, n = 47 students). Outcome measurements included assessment of students' performance in tutorials individually and as a group, end-unit examinations scores, assessment of tutoring skills and identifying students' perceptions about peer tutoring. Student tutors were perceived better in providing feedback and in understanding the difficulties students face in tutorials. Tutorial atmosphere, decision-making and support for the group leader were better in SLT compared with FLT groups. Self-assessment of student performance in SLT was not different from FLT. Student scores in the written and practical examinations were comparable in both groups. However, SLT groups found difficulties in analysis of problems presented in the first tutorial session. We conclude that the impact of peer tutoring on student performance in tutorials, group dynamics, and student achievement in examinations is positive overall. However, student tutors require special training before adopting this approach in PBL programs.

Anthropometric and body composition indicators of Bahraini adolescents.

BACKGROUND: Childhood and adolescent obesity tends to extend into adulthood and predisposes the individual to some chronic diseases in later life. Body composition is a good indicator for assessing obesity and nutritional status of people. AIM: To determine the anthropometric and body composition characteristics of Bahraini adolescents and to compare these measurements with previously published data on the same age group. SUBJECTS OF METHODS: Cross-sectional data on 506 Bahraini adolescents (249 boys and 257 girls) aged 12-17 years were collected in 2000. The sample was selected from intermediate and secondary schools using a multistage stratified sampling procedure. Anthropometric measurements, including weight, height, mid upper arm circumference, waist and hip circumference, triceps, subscapular and medial calf skinfold thickness, were performed on the adolescents. Body mass index (BMI), percent body fat, arm muscle circumference (AMC), arm muscle area (AMA), arm fat area (AFA), waist/hip ratio (WHR), and subscapular/triceps skinfold ratio (STR) were also calculated. RESULTS: A sexual dimorphism that appears to be related to differential changes in body composition during puberty was observed. The findings showed that mean BMI, skinfold thickness and percent body fat were all higher than those reported in earlier studies on Bahraini adolescents of corresponding age range, indicating an increase in fat accumulation among the adolescent population. Bahraini adolescents were found to be shorter and of similar weight or even heavier than their Western counterparts, indicating a greater trend of obesity among Bahraini adolescents. CONCLUSION: A trend of greater obesity appears to have occurred in the Bahraini adolescents during the period between 1986 and 2000. These findings have important public health implications given recent evidence linking childhood and adolescent obesity to increased risk of obesity and morbidity in adulthood. Therefore, programmes to prevent the development of obesity in children and adolescents should be given a high priority.

Gender-related differences in learning in student-led PBL tutorials.

CONTEXT: Male and female students behave differently in problem-based learning (PBL) tutorials. However, these differences could be partly attributed to faculty tutor behavior in male and female tutorials. OBJECTIVES: This study aims to examine the gender differences in learning outcomes between medical students when peer tutors facilitate PBL tutorials. METHODS: A questionnaire-based study conducted in single-gender student-led (SLT) and faculty-led (FLT) tutorials. The study involved third year medical students (n = 91) divided into ten groups (five groups each). The SLT groups consisted of 16 male and 28 female students, while the FLT group consisted of 20 male and 27 female students. Students evaluated their individual and group performance in tutorials and also skills of tutors. Student performance in end-unit examinations and their perceptions about peer tutoring were also analyzed. RESULTS: A total of 290 questionnaires (response rate = 63.7%) were collected over the five-week period of the study. Although individual performance in tutorials and achievement in examinations were comparable in both groups, there was significantly higher group performance in female compared with male student-led tutorials (p < 0.01). This difference between male and female groups was not attributed to improvement in the performance of female groups, but rather to a decline in performance of the male SLT groups. In addition, both male and female students expressed facing difficulties in discussion and analysis of the problem in the first tutorial session. CONCLUSIONS: Understanding the gender differences in the group behavior in student-led tutorials is important for PBL programs adopting this approach.

Body weight perception among Bahraini adolescents.

BACKGROUND: This study examines the relationship between actual weight status and perceptions of body weight in Bahraini adolescents. The study also investigates the adolescents' perceptions of parents' and peers' opinions of weight. METHODS: A cross-sectional survey of 447 Bahraini male and female adolescents aged 12-17 years was conducted. Weight and height were measured and body mass index (BMI) was calculated. A short questionnaire was used to obtain their attitudes towards their weight status, as well as the attitudes of their parents and friends. The nine figure silhouettes illustration was used to measure perception of ideal body image and how it compares with their current body weight. RESULTS: The results revealed a significant discrepancy between adolescents' perception of body weight and actual BMI. There was a tendency for teenagers to underestimate their weight status, which was especially noteworthy among the overweight and obese. More than half of the girls and about one-third of the boys expressed discontent with their current body weight. One-third (33.5%) and 26.6% of the adolescents thought that their parents and their peers, respectively, would consider them to be overweight or obese. The percentage of adolescents who reported parental or peer underestimation was higher among those classified as overweight or obese than it was among those who were of normal weight. CONCLUSION: The study shows the existence of a distorted body image as reflected by failure of many overweight or obese adolescents to perceive themselves as such. Among Bahraini adolescents weight-related beliefs and attitudes exist at two ends of the spectrum: a tolerance of obesity at one end and an exaggerated concern for its occurrence at the other.

Problems for problem-based learning: a comparative study of documents.

In medical education the problem-based approach to learning can be considered as the most significant educational innovation in the past two decades. This paper examines the ways and extent to which health problems have been designed for implementation of problem-based curriculum. Content analysis of curriculum documents of three problem-based schools was carried out in a systematic way from identification of unit of analysis, categorization, sampling, data analysis and interpretation. The comparative study revealed common areas in curriculum organization, arrangement of problems in stages, problem selection criteria, and basic concepts in the early stages of the curriculum. About one-third of the health problems were found to be similar in the schools compared. However, there was no uniformity in the sequence of organ-systems or the health problems. This study provides a framework for the development of problem-based curriculum in three stages with essential concepts identified for the first stage. Criteria for a balanced selection of problems and problem design features which affect the quality of health problems have been identified. These findings could be of value for those who are in the process of developing or revising a problem-based curriculum.

Reliability of ICD-10 research criteria: an Arab perspective.

Within a broader World Health Organization (WHO) collaborative research around the ICD-10 diagnostic criteria for research, the Regional Office for the Eastern Mediterranean (EMRO) ICD-10 research coordinating center at the Ain Shams Institute of Psychiatry presented the data collected from 8 Arab centers, which investigated a total of 233 patients using the local psychiatric interview schedules and diagnosed according to ICD-10 criteria. Interrater reliability was found to range between an almost perfect (0.81-1) to substantial agreement (0.61-0.80) (using the kappa coefficient) in diagnosing organic mental disorders, substance use disorders, schizophrenic, schizotypal and delusional disorders, affective disorders and neurotic and stress-related disorders. The categories of psychological development and child and adolescent disorders were diagnosed less frequently and the agreement between raters was lower. Though no culture-bound syndromes were encountered in any of the centers, difficulties in diagnosis using the research criteria were identified in the domain of simple schizophrenia and dissociative versus conversion disorders. These difficulties are discussed in consideration of the experience of our psychiatrists.
