Introduction: Recently, Intermittent Fasting (IF) has gained popularity as an effective approach for obesity management. Many types of IF have been practiced for either religious or health purposes. Muslims, for example, are encouraged by Islam to voluntarily fast two days/week (Monday and Thursday) from sunrise to sunset. Aim: This study investigated the association between Muslims’ voluntary fasting (two days/week) with Body Mass Index (BMI), Physical Activity (PA), and sleep pattern. Materials and Methods: The present survey-based study was conducted for three months on 1242 adults (245 males and 997 females) who completed the completed self-administered study questionnaire. The questionnaire comprised questions on sociodemographic and anthropometric variables, fasting-related questions, PA, and sleep pattern. Participants were classified into fasting and non-fasting groups according to their responses to the question “Do you fast two days (i.e., Monday and Thursday) every week? The differences between the two groups were tested using Chi-square test, an exact probability test and unpaired t-test. Results: A total of 1,242 valid responses (age 18 years and above) were collected. Among those participants, only 18.4% (n=229) reported fasting Monday and Thursday every week. The BMI of those who used to fast two days/week was significantly higher (p < 0.05) than those who did not fast. The desire to lose weight (47.59%), followed by religious views (44.54%) were the main reasons for fasting. A significant difference (p < 0.05) in PA was observed between the two groups, but overall, the participants were involved in low PA only. No significant differences (p ≥ 0.05) in sleep pattern, such as sleepiness during the day, and sleep duration were observed between the two groups. However, significant differences in the time required to sleep and waking up during sleep were found between the two groups. Conclusion: This study indicated that fasting two days/week does not affect BMI when meal timings are restrained to early evening and pre-dawn periods, with adequate night sleep. It may be an appropriate beginning point to further develop strategies to sustain any beneficial effects of the voluntary IF on obesity.

Aim: Identify the relation between poor esteem for body image and weight-related behaviors. The results will help increase awareness and improve students’ lifestyles to have a better body image and achieve ideal body weight. Methods: A cross-sectional study was conducted among King Abdulaziz University medical students (n= 460) between July to the end of August 2019. Data was collected using the International physical activity questionnaire (IPAQ), figure rating scale (FRS) and analyzed using SPSS software. Result: The results showed that the average Body Mass Index (BMI) was 24.80 ± 11.89. Participant sex was an important factor influencing the prevalence of obesity; male students were more obese than female students with a significant difference (p<0.001). The level of body satisfaction was also affected by gender. Students in preclinical years were more likely to gain weight more than clinical years students. Conclusion: The results show a significant relationship between body satisfaction and gender (P<0.0001) despite having diverse BMIs. Overweight and obese males and females' participants had the lowest body satisfaction. Females who were too thin and had low BMIs described themselves as normal, while males describe themselves as too thin. Conversely, females with high BMIs described themselves as too fat, while males described themselves as normal. This could be due to different factors. Also, underweight females and males have high body satisfaction, which can lead to dangerous behaviors to maintain low body weight which cause negative health consequences.

AbstractBackgroundChildren with congenital cardiac disease experience challenges in developing healthy patterns of physical activity due to decreased exercise capacity and parental fear and confusion about what is permissible. The purpose of this study was to describe physical activity habits in children 10–14 years of age with congenital cardiac disease and the relationship of those habits to obesity as defined by body mass index.MethodsThis cross-sectional study used self-report measures and clinical data to describe the association between physical activity participation and body mass index in 10- to 14-year-old children with congenital cardiac disease. Further, physical activity levels were compared between children who were overweight or obese and those who were not.ResultsChildren (n = 84; 51 males; 33 females) reported low rates of physical activity compared to reports on healthy children. Only 9.5% were overweight (body mass index between the 85th and 94th percentile), and alarmingly 26% were obese (body mass index at or above the 95th percentile). Physical activity and body mass index were not significantly correlated (r = −0.11, p = 0.45) and there was no significant difference in mean physical activity (t = 0.67) between children who were overweight or obese and those who were not.ConclusionsChildren in this study reported low rates of physical activity and a higher obesity rate than was reported in previous studies. However, the two were not significantly correlated. Further research is indicated to determine the specific factors contributing to obesity and to test interventions to combat obesity in children with congenital cardiac disease.

Background and Objectives: Estimation of dental age is based upon the rate of development and calcification of tooth buds and their progressive sequence of eruption in the oral cavity. The tooth calcification provides a valuable indicator of dental age and serves as an index of the maturation of the child. The aim of this study is to determine whether Body Mass Index (BMI) has association with dental maturation. Materials and Methods: A cross sectional study design was applied for the present study, 383 school children were participated in this study which nominated from Erbil city. For the sample to be representative the city was divided in to six geographic areas according to the municipalities, the samples randomly selected school children of 10 to 14 years old from both genders. The height and the weight of each participant had been recorded in the college of dentistry / Hawler Medical University in order to calculate the body mass index of the following the guidelines of centers of disease control (CDC) , at the same time an orthopantomography radiograph had been used to investigate the stage of the dental maturation using the Demirjian method, finally, the relationship between BMI and dental maturation were investigated using chi square test with P value of ≤ 0.05 was considered significant difference. Result: there was a statistically significant relationship between dental maturation and BMI. The majority (93.6%) of samples with under-mature dentition were under-weight at the same time. The vast majority (96%) of samples with mature dentition had normal BMI. In the same manner, majority (91.7%) of samples with over mature dentition were over-weight too. Chi square test was used to find out the association and P-value was 0.001 Conclusion: In conclusion, normal weight students have normal dental maturation, underweight students have under dental maturation and overweight or obese students have over dental maturation. Keywords: body mass index, Demirjian, Orthopantomography.

This study evaluated the accuracy and predictive value of body mass index (BMI) in evaluation of obesity and body fatness. Data on BMI and percent body fat (PBF) were collected on 953 male police officers who were allocated into age groups: 20-29 years, 30-39 years, and 40-49 years. BMI > 30.0 kg/m2 and PBF > 25% were classified as obese, and those with lower values were classified as non-obese. Chi-square was used to evaluate the accuracy in classification in obese and non-obese when officers’ BMI was matched to PBF. Pearson’s correlation and linear regression analyses determined the prediction value of BMI. Chi-square revealed significant difference in obesity prevalence when evaluated by BMI and PBF, with classification accuracy of 44.5%-71.8%, depending on age. BMI had moderate prediction value of body fatness. If the assessment of PBF is not attainable, BMI needs to be used carefully as it is likely to underestimate obesity among police officers.

Chemotherapy Dose

e13099 Background: Obesity has increased to epidemic proportions, with 32.2% of US adults aged 20 years or older classified as obese (body mass index ≥ 30 mg/m2). In view of altered pharmacokinetics and possible excessive toxicity in obese patients, chemotherapy dose reductions are often employed in treating obese cancer patients. To our knowledge, there are no reports in the literature identifying patients who should have empiric dose adjustment because of obesity or the best method of dosing chemotherapy to standardize drug exposure in patients with varying degrees of obesity. As practice varies among institutions, we carried out a retrospective study to evaluate the chemotherapy dosing pattern in our obese patient population. Methods: Charts of patients who received chemotherapy at our institution during the year 2010 were reviewed. Data on age, height, weight, type and stage of cancer, date of chemotherapy, and type and dose of chemotherapy were retrieved from chart review. Only details of the first chemotherapy cycle at our institution were collected. Body surface area (BSA) was calculated by using the Mosteller formula. Independent samples t-test and Pearson chi-square statistics were used to investigate the difference between the means and proportions respectively. Results: Data from 191 patients were analyzed. Distributions (mean and range) of age, height, weight, body mass index (BMI) and BSA were 60 years (26 - 88), 65 inches (53 - 79), 166 pounds (90 - 340), 27.44 kg/m2 (14.52 - 56.57) and 1.85 m2 (1.36 - 2.66), respectively. Patients who had a full dose (n = 164) had a mean BMI of 27 kg/m2 (standard deviation (SD) 6.5) and a mean BSA of 1.82 m2 (SD 0.24) whereas those with a reduced dose had BMI (n = 27, mean 30.2, SD 7.1) and BSA (mean 1.97, SD 0.25). There is a significant difference between the means of the two groups (full dose and reduced dose) in terms of both BSA and BMI (p = 0.033 and p = 0.01, respectively). Significantly higher proportion of patients with BSA ≥ 2 received reduced dose compared to those with BSA < 2 (14 out of 48 (20.3%) versus 13 out of 143 (9%), p = 0.001). Conclusions: Patients with BSA ≥ 2 were more likely to get empiric chemotherapy dose adjustment at our institution. Further studies on chemotherapy dosing in obese patients are warranted.

(1) Purpose: Conflicting information exists regarding the relationship between obesity, leisure-time physical activity (PA), and disability in people with multiple sclerosis (PwMS). We aimed to investigate the association between leisure-time PA and weight status in a relatively large cohort of PwMS. Furthermore, we examined this relationship according to the level of neurological disability. (2) Methods: The study included 238 PwMS (138 women) with a mean Expanded Disability Status Scale (EDSS) score of 2.5 (standard deviation [SD] = 1.7), mean disease duration of 6.4 (SD = 8.2) years, and mean age of 40.5 (SD = 12.9) years. Obesity was defined using two different metrics, each based on body mass index (BMI). Leisure-time PA was determined by the Godin–Shephard leisure-time PA questionnaire. Statistical analyses included multivariate logistic regression, the chi-square test, and Pearson coefficient correlations. (3) Results: The unadjusted odds ratio (OR) between leisure-time PA and BMI based on the World Health Organization’s (WHO) definition was 1.070 (p = 0.844) for overweight and 1.648 (p = 0.254) for obesity. The adjusted OR was 1.126 (p = 0.763) for overweight and 1.093 (p = 0.847) for obesity after adjustment for age, gender, and disability status. Chi-square analysis revealed no significant correlation between leisure-time PA and obesity (p = 0.564) according to the BMI threshold for PwMS. The unadjusted OR (95% confidence interval [CI]) between disability level and BMI based on the WHO definition was 1.674 (p = 0.220) for overweight and 0.618 (p = 0.460) for obesity. The adjusted OR was 1.130 (p = 0.787) for overweight and 0.447 (p = 0.234) for obesity after adjustment for age, gender, and leisure-time PA. Similarly, chi-square analysis revealed no significant correlation between disability level and obesity (p = 0.701) per the BMI threshold for PwMS. (4) Conclusions: No association was found between leisure-time PA and BMI in PwMS. An additional finding was the absence of any association between obesity and neurological disability level in the multiple sclerosis cohort.

Background: Body mass index (BMI) is frequently labeled as “flawed” in assessing obesity since it cannot differentiate between muscle and fat leading to misclassifications of healthy individuals. Bioelectrical impedance analysis (BIA) may be a more accurate indicator of obesity since it can distinguish the difference between muscle and fat in children. This pilot study investigated discrepancies between BMI and BIA body composition classifications in children with high levels of physical activity.Methods: Participants were selected from three elementary schools (N = 380, K = 76, 1st = 64, 2nd = 62, 3rd = 61, 4th = 83, and 5th = 34) receiving 60 min of outdoor, unstructured play daily. BIA scales were used to collect each child's body fat percentage and BMI score, then those numbers were categorized by BIA and BMI normative values as either underweight, healthy, overweight, or obese.Results: Overall, 26% of the students were classified differently when using the normative classifications for BMI and BIA, with the largest discrepancy found in the overweight category at 38%. Similar inconsistencies were found when students were divided as younger (42%) vs older students (36%), and males (40%) vs. females (35%).Conclusions: This pilot study demonstrated that there is a significant difference in how BMI and BIA discriminate between the different body composition categories. BIA consistently shows to be a more accurate tool in assessing obesity rates in children since it directly measures body fat.
