Objectives: To estimate obesity prevalence among children and adolescents in Al-Ahsa, Saudi Arabia for the year 2016 and to determine the related preventable risk factors. Methods:This study was a cross-sectional study (using stratified random sampling representing different geographical areas of Al-Ahsa) through a self-administered questionnaire. It included 240 male students aged (7-15) years old from public primary and intermediate schools in Al-Ahsa governorate, Kingdom of Saudi Arabia. Anthropometric measurements of weight and height were taken for all the study participants. Body mass index (BMI) and its percentile was determined using Saudi won growth charts of the corresponding age and sex. Results:The overall prevalence of overweight and obesity was 29.6% (10.8% overweight, 3.8% obese, and 15% extremely obese). The prevalence of overweight and obesity was significantly associated with early childhood obesity, parental obesity, mother's employment, family income, number of snacks and fast food consumption, physical inactivity, and time spent in watching television. Other factors (namely, eating during emotional stress, family gathering on meals, and regular eating times) were having independently significant association. Conclusion:There is an urgent need to spread awareness about obesity, and the prevention programs that involving schools and families are the key strategy for controlling the current epidemic of obesity.

To evaluate direct cost of in-vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) cycle and reproductive outcomes among infertile women with different body mass index (BMI).Methods: A retrospective study of 826 subfertility patients who had IVF or IVF-ICSI in 2017 to 2018 were reviewed. The patients were divided into 4 groups bestowing to BMI to normal weight (18.5-24.9 kg/m 2 ), underweight (<18.5 kg/m 2 ), overweight(25-29.9 kg/m 2 ), and obese(≥30 kg/m 2 ). Data on treatment costs of IVF/ICSI and reproductive outcomes were collected and analyzed. A total of 338 patients (40.9%) were overweight, and 300 (36.3%) patients were obese. A bottom-up methodology was used to measure the resource utilization. The Original Article capital inputs needed for individual procedures were defined and calculated by consulting with appropriate clinicians and priced using market prices for 2017-2018.Results: There was no statistical significant difference for live birth rate (LBR) among the BMI groups, with the occurrence of LBR in 23 women with normal BMI (13.1%), in 48 (14.2%) women who were overweight, in 48 (16%) in women who were obese (p=0.7). The median cost for IVF/ICSI treatment cycle did not differ across BMI groups; the cost was 10,380 SAR for women of normal weight, 10,440 SAR for women who are overweight and obese (p=0.6). Conclusion:Our results suggest that costs of IVF/IVF-ICSI is not significantly affected in women who are overweight or obese.

O Google Acadêmico e outras redes de pesquisa por materiais acadêmicos disponibilizam grande quantidade de informação na Internet. Em diversos casos não é possível fazer consulta e análise mais detalhada das informações. Esta pesquisa propõe utilizar Follow Model como ferramenta para categorizar os nós de uma rede. Como o Follow Model apresenta grande potencial para trabalharmos com redes sociais online, ele foi adaptado para podermos fazer classificação de nós, assim como os modelos do PageRank, e InventorRank, no estudo da MRSA. O estudo demonstra como o Follow Model é robusto e como podemos melhorar consultas de material acadêmico.
