Life style Factors Influencing BMI of Females In Ha’il Region

Background: Published health promoting or health risk behaviors data in a young population is sparse for Saudi Arabia. Identifying health risk factors early in life and promoting primary prevention interventions among the youth is of utmost importance to move in a healthier direction Objectives: The aim of this study is to identify the socio-economic factors influencing BMI in female students in University of Hail. Methodology: A cross sectional survey was carried out to evaluate dietary behaviors in a random sample of 200 adolescent students, from UOH female campus during the winter semester. Self administered questionnaire for dietary behaviors was used for survey by following anonymity and privacy. Results: This study was conducted to measure BMI and determine the socioeconomic factors affecting the relative weight of young adult females living in the city of Ha’il, Saudi Arabia. A total of 200 female subjects (mean ± SD: age: 19.76 ± 1.98 years and BMI: 23.47 ± 5.58 kg/m2) participated in the present survey. 28.5 % percent of study sample were either overweight or obese. Age wise distribution indicates overweight and obesity significantly increases with age. Breakfast is frequently skipped in overweight and obese subjects while frequency of snacking less among them. Findings of the current study also suggest habit of frequent snacking behavior inverse association with BMI. The current study findings have indicated no clear impact of physical activity on obesity prevalenc

The importance of the film structure during self-powered ibuprofen salicylate drug release from polypyrrole electrodeposited on AZ31 Mg

Therapeutic drugs uploaded into conjugated conductive polymer matrices deposited on active magnesium alloys serve as controlled dose, self-powered drug delivery systems. Preferentially drugs are added into polymer films in the largest amount possible, mostly to prevent long-term treatments. However, added drugs might interact with the polymer matrix affecting either the structure or the final mechanical properties of the polymer film. In this work polypyrrole films (PPy) electrodeposited on an AZ31 Mg alloy in ibuprofen and salicylate containing solutions are investigated in terms of their uploading capacity, surface morphology and mechanical properties. The techniques used to investigate the uploaded PPy films include cyclic voltammetry (CV), SEM, EDS and depth-sensing indentation (DSI). A maximum ibuprofen concentration of 440±40 µg cm-2 was obtained in PPy films in the presence of sodium salicylate. The release fraction of ibuprofen as a function of time is fitted to Avrami’s equation. The hardness and reduced modulus decreased by 54% and 40% respectively, when the Ppy films are prepared in the presence of sodium ibuprofen compared with those prepared in sodium salicylate only, indicating a more plastic film with ibuprofen

A normative study of the raven coloured progressive matrices test for omani hildren aged 5-11 years*

Raven’s Coloured Progressive Matrices test has been extensively used across a wide variety of settings in different countries all over the world as a fair culture measure of non-verbal intelligence. The objective of the present study is to extract norms of the test for Omani children. The test was applied on an individual basis on a random sample of 1042 children from different age groups ranging from 5 to 11 years old. All of the estimated psychometric properties including validity, reliability, and norms indicate that the test could be practically utilized when applied in several situations. The study has a number of implications including that the Ministry of Education may use it to diagnose and detect those children with learning difficulties; the Ministry of Health may use it in hospitals to measure the IQ of certain patients in order to make medical decisions. In addition, researchers in psychological and social areas would be able to conduct studies aiming at measuring the intelligence of children
