A Furstenberg-Katznelson-Weiss type theorem on (d + 1)-point configurations in sets of positive density in finite field geometries

We show that if $E \subset \mathbb{F}_q^d$, the $d$-dimensional vector space over the finite field with $q$ elements, and $|E| \geq \rho q^d$, where $q^{-\frac{1}{2}}\ll \rho \leq 1$, then $E$ contains an isometric copy of at least $c \rho^{d-1} q^{d+1 \choose 2}$ distinct $(d+1)$-point configurations

Evaluation of school health instruction in public primary schools in Bonny Local Government Area, Rivers state

Background: Effective school health instruction in primary schools is  essential in addressing the health risks and needs of school age children and adolescents. This study sought to evaluate the status of schoolhealth instruction in public primary schools in Bonny Local Government Area.Method: This is a cross sectional school based study carried out in 20 public primary schools in Bonny Local Government Area, Rivers State, in March 2006. The availability of the various components of the school health instruction programme was evaluated using an evaluation scale. Components had weighted scores. The minimum acceptable and maximumattainable scores for school health instruction were 31 and 47. Data was analyzed using SPSS version 11.Results: There were a total of 100 teachers in all the schools. The teacher population per school ranged from 2 to 13 with a mean of 5±2.77SD. The pupil population of the schools ranged between 100-1460 with a mean of352±336SD. Teacher/pupil ratio per school ranged from 1: 30 to 1: 128. Fourteen (70%) schools had teacher/pupil ratio less than 1:40. There was no professional health instructor in all the schools. Four schools (20%) allotted 3 periods per week to health teaching, while the rest (80%)  allotted less than 3 periods per week. HIV/AIDS was not in the health education curriculum being used. The only teaching method used by all the schools was the direct teaching method. No school used teaching aids; noschool went on field trips. Teachers did not receive in-service training on health education. No school attained the minimum acceptable score of 31 points using the evaluation scale.Conclusion: School health instruction was poorly implemented in the primary schools investigated. Teachers were not adequately prepared for health teaching and the classrooms were overcrowded.Keywords: School; Health instruction, Evaluatio

Hand washing practices amongst medical students in Port Harcourt, Nigeria

Background: Hand washing with soap and water is one of the most effective and inexpensive means of preventing infections. Rates of hand washing are low world wide even amongst health care workers who are should know about its importance. The aim of the study was to evaluate the knowledge, attitudes and hand washing practices both in and outside the hospital amongst medical students in Port Harcourt.Method: This was a descriptive cross sectional survey carried out amongst randomly selected fourth to sixth year medical students of the University of Port Harcourt. A simple questionnaire exploring perceptions, attitudes and self reported behavior was used. Information obtained included biodata, awareness information and practice. Data were analyzed using descriptive statistics.Results: Two hundred and sixty one students participated in the study with a M: F of 1.5:1. Diarrhea diseases were most commonly recognised as being associated with contaminated hands. 37.6% washed their hands regularly after interacting with their patients while 33.9% did so only after the days work. 58.3% and 58.9% washed hands before meals and after defecating respectively. Use of soap was generally low. The greatest motivation for hand washing was fear of contracting disease, whilst constraints included lack of soap, forgetfulness and inconveniently located sinks.Conclusion: Hand washing rates are low amongst medical students in Port Harcourt. There is need for regular education and re-education.Key words: Hand washing practices; medical students; Port Harcourt

Prevalence of overall and central obesity among adolescent girls in Port Harcourt: a comparison of different methods

There is no universally accepted criterion for classification of overall weight status and central obesity in adolescents. Several criteria have been used which include that recommended by Centre for Disease control, World Health Organization and the International Obesity Task Force.Aim: The study compared various methods for determination of overall obesity in adolescents using the BMI percentiles recommended by the Centre for Disease Control (CDC), the International Obesity Task Force (IOTF) and the World Health Organization (WHO) BMI Z score and determination of central obesity using the waist circumference (WC), Waist Hip Ratio (WHR) and Waist Height Ratio (WHtR).Methods: The study subjects consisted of 1320 girls aged 10-19 years from randomly selected girl’s high school. Weight status to determine overall obesity was determined according to the CDC, IOTF and WHO criteria and central obesity determined using the WC, WHR, and WHtR. Comparison of methods was done and analysed.Results: Prevalence of overall and central obesity varied with different methods. The prevalence of overall obesity was 106(8.02%), 69(5.22%) and 39(2.75%) using the CDC, WHO and IOTF criteria respectively. Prevalence of central obesity was 1.5%, 16.26%, 47.81% using the WC, WHtR, and WHR respectively. The agreement between criteria of WHO Z score and BMI Percentile was highest for overall obesity. (K=0.81). There was a statistically significant association between overall weight status and central obesity using the different criteria of determination of central obesity.Conclusion: Prevalence of overall obesity and central obesity varied based on the methods used. The highest level of agreement for overall obesity determination was obtained between WHO Z score and BMI percentile compared to WHO Z score and IOTF criteria. Prevalence of central obesity increased significantly with overall obesity in study population.Key words: adolescents, Girls, overall and central obesit
