Abstract
This study aims to reveal the feelings, difficulties, attitudes, and spiritual coping status of Turkish patients with Type 2 diabetes mellitus toward fasting during Ramadan. The sample of this descriptive qualitative study consists of 14 patients diagnosed with Type 2 diabetes. We determined two main themes and relevant sub-themes. The first was "the feelings and difficulties experienced due to diabetes mellitus" with the sub-themes of "negative emotions" and "difficulties in fasting." The second theme was identified as "religious and spiritual coping" with the sub-themes of "believing the disease comes from God," "having difficulty in adhering to disease-specific practices while fasting," and "feeling that fasting facilitates coping and provides relief." In conclusion, it was determined that the patients continued to fast despite the difficulties and that fasting facilitated coping and provided relaxation.

Perspective of biopharmaceutics knowledge and practice of pharmacy personnel toward the effect of medication route and medical procedure on nullifying fasting. Saudi Pharm J 2023; 31:101747. [PMID: 37638218 PMCID: PMC10448202 DOI: 10.1016/j.jsps.2023.101747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 08/06/2023] [Indexed: 08/29/2023] Open
Abstract
Background In Ramadan, most of the dosing schedules for the patients are changed, and to ensure patient compliance to medications and to healthy life among patients, appropriate guidelines and educations are needed. This can be achieved by pharmacy personnel in all clinical settings who are recognized as biopharmaceutical experts and integral educators of medications. Aims This study aimed to identify the perspective knowledge of pharmacy personnel about effect of medication route and medical procedure on nullifying fasting in Ramadan and to determine the predictors of this knowledge. Methods A cross-sectional study was conducted in Jordan during March-April 2022. An internet-based self-administrated questionnaire on knowledge, and views was distributed using social media groups to the pharmacy personnel among different geographical areas in Jordan. A descriptive and univariate analysis were performed. Binary logistic regression was conducted to determine the predictors of knowledge including all variables with p < 0.20 on univariate analysis. Results A total of 1003 responses to the study questionnaire were collected and included in the analysis. The most common source that pharmacy personnel used to get information on medication intake and medical procedures during fasting in Ramadan was Fatwa (57.8%) followed by Islamic materials "books and brochures" (47.1%). The majority of respondents were knowledgeable about the effect of administration route of medication and medical procedures on nullifying fasting in Ramadan (greater than70%). The univariate analysis showed that more than half of respondents (56.1%) were considered knowledgeable, and the binary logistic regression analysis identified that both professional degree type and confidence of respondents to modify the patient's medication schedule as predictors for knowledge (OR = 1.791, 95% CI = 1.035-3.098, p = 0.037), (OR = 1.375, 95% CI = 1.04-1.817, p = 0.025), respectively. Conclusions Most of pharmacy personnel in Jordan are knowledgeable in biopharmaceutics principles and practice toward effect of medication route and medical procedure on nullifying fasting, and the identified predictors for this knowledge, can provide an opportunity to improve safe and effective use of medications and medical procedures during the holy month of Ramadan.

Abstract
Abstract
Background
Millions of Muslims around the world fast during the holy month of Ramadan as a requirement of their religion Islam. Studies have reported varying effects of Ramadan fasting on mental health and various hormones. This study aimed to examine the effects of Ramadan fasting on mental health and plasma Leptin, Ghrelin, Neuropeptide Y (NPY), Growth Hormone levels in healthy individuals, and to evaluate the possible relationship between their hormone values and scale scores. Male healthcare professionals working at a university hospital without any psychiatric disease were included in the study. In the last week before Ramadan and in the first week after Ramadan, participants’ blood samples were taken at 8.00 in the morning after 12 h of fasting, taking into account the release pattern and pulsatile release of these hormones in order to measure plasma Leptin, Ghrelin, NPY and Growth Hormone levels. Simultaneously, a sociodemographic data form, the Brief Symptom Inventory (BSI) and the Scale of Dimensions of Interpersonal Relationships were applied to participants.
Results
The sample of the study included a total of 40 healthcare professionals. Participants’ BSI interpersonal sensitivity and phobic anxiety subscales scores and their general severity and positive symptom distress index scores decreased significantly after Ramadan compared to those measured before Ramadan. (p < 0.001, p = 0.020, p = 0.042, p = 0.006 respectively). Also participants’ ghrelin levels increased significantly after Ramadan compared to those measured before Ramadan (p < 0.001).
Conclusions
The effects of Ramadan fasting on mental health may be mediated by some psychoneuroendocrine mechanisms. In order to elucidate these mechanisms that mediate the effect of Ramadan fasting on mental health, there is a need for better-structured studies with larger samples and more variables.

Nutrients 2023; 15:nu15030756. [PMID: 36771469 PMCID: PMC9921927 DOI: 10.3390/nu15030756] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/19/2023] [Accepted: 01/30/2023] [Indexed: 02/05/2023] Open
Abstract
Much evidence suggests that food intakes and eating patterns are major determinants of the phase of peripheral circadian clocks, and desynchronization between them is thought to contribute to the development of metabolic disorders. However, much remains to be understood about how different dimensions of chrononutrition during pregnancy affect pregnant women's and their offspring's health outcomes. Therefore, we systematically reviewed and integrated all emerging evidence on chrononutrition during pregnancy (including meal skipping, meal frequency, night eating, and (Ramadan) fasting) and their relationships with maternal and offspring outcomes. The results suggest that meal skipping and night eating during pregnancy were generally associated with adverse pregnancy and birth outcomes, whereas no strong conclusion could be reached for meal frequency. In our meta-analysis, Ramadan fasting did not seem to be related with birth weight or gestational age at birth, but evidence for other mother-offspring outcomes was inconsistent. To further elucidate the effect of chrononutrition factors on maternal and offspring health outcomes, larger and well-conducted prospective cohort and interventional studies are needed. In addition, information on covariates such as physical activity, sleep, diet quality and quantity, fasting days, fasting period per day, and trimester exposure should also be collected and considered during analysis.

Abstract
Purpose Impact of ramadan fasting on healthy and women with diabetes is already known. However, there is a scarcity of data on impact of fasting on pregnant women with diabetes. Moreover, religious and medical recommendations advise pregnant women against fasting as it is unsafe. Despite being exempted, many pregnant Muslim women with diabetes still choose to fast during ramadan. This study investigated different glycemic marker as an indicator for diabetes control in fasting pregnant women. Patients and Methods This is a prospective observational study. A total of 89 pregnant diabetes women were recruited. Blood glucose was self-monitored in all the pregnant women using glucose monitoring device at home. We measure the fructosamine, HbA1c levels before, during and after ramadan. Results Pregnant women with type 1 diabetes were 14 (25%), type 2 diabetes were 21 (37.5%), and gestational diabetes were 21 (37.5%). The mean fructosamine level decreased during and after ramadan in gestation diabetes pregnant women compared to type 2 diabetes and type 1 diabetes pregnant women subjects (p = 0.009). Conclusion The present study indicates that pregnant women with diabetes were able to fast during ramadan and there fructosamine level reduced during fasting. Utilization of fructosamine for short-term monitoring of glycemic control in addition to home glucose monitoring in pregnant women with diabetes will provide a good index of glycemic control. Recommendation Religious and medical recommendations advise pregnant women against fasting as it is unsafe, and they are under high risk. However, if they insist to do fast, they must do under strict medical supervision and fructosamine can be used as a glycemic control marker.

Abstract
INTRODUCTION During Ramadan, repeated cycles of fasting might contribute to changes in blood pressure among hypertensive patients. Studies on the effects of fasting on the blood pressure of hypertensive patients are scarce and have provided inconclusive results. AIM To examine the effect of fasting on ambulatory blood pressure and heart rate in treated hypertensive subjects. METHODS The study prospectively recruited 60 hypertensive patients between April and June 2019, followed up at the cardiology department of Habib Thameur Hospital of Tunis. A 24-hour pressure monitoring was carried out during two periods: prior to Ramadan and during the last ten days of Ramadan. We compared the average values of 24 hour, awake and asleep systolic and diastolic blood pressure and 24 hour, awake and asleep heart rate. RESULTS We studied 40 women and 20 men; mean age was 58.4 years. 33% of the patients were diabetics, 42% dyslipidemics, 15% had coronaropathy. 45% of the patients were on monotherapy, 37% on dual therapy and 18% on a triple antihypertensive therapy. During Ramadan, 74% of the patients were taking the treatment once daily, 3% twice daily, and 23% three times per day. Average 24hour ambulatory blood pressure in the whole group was 129±17/74±10 mmHg before Ramadan and 128±17/73±9 mmHg during Ramadan (p>0.05). Daytime and nighttime mean values of systolic and diastolic blood pressure as well as mean values of heart rate were not different between both periods regardless of age, gender, medical history and lifestyle. CONCLUSIONS In this study, there were no significant changes in systolic and diastolic blood pressures as well as heart rate during the 2 periods.

Abstract
Obesity is a significant driver of the global burden of non-communicable diseases. Fasting is one approach that has been shown to improve health outcomes. However, the effects of Ramadan fasting differ in that the type, frequency, quantity, and time of food consumption vary. This phenomenon requires in-depth evaluation considering that 90% of Muslims (~2 billion people) fast during Ramadan. To address this issue, we evaluated the pattern of weight change during and following Ramadan for a total of 52 weeks. The study was conducted in Amman, Jordan. Between 2012 and 2015, 913 participants were recruited as part of a trial investigating the efficacy of a weight loss intervention among those with or at risk for diabetes. Weight was measured weekly starting at the beginning of Ramadan, and changes were analyzed using discrete and spline models adjusted for age, sex, and trial group. Results show slight weight gain within the first two weeks and weight loss in the subsequent weeks. During the first week of Ramadan, the estimate for a weight reduction was 0·427 kg, (95% CI: -0·007, 0·861), increasing to 1·567 kg, (95% CI: 2·547, 3·527) at week 26. There was clear evidence of gradual weight gain from about 4 to 15 weeks and a drop towards the end of the investigation at week 28 (-0·12kg, 95% CI: -0·89, 0·56). Our results show that weight changes occurred during and after Ramadan. Weight fluctuations may affect health risks, and thus, findings from this study can inform interventions. Public health agencies could leverage this period of dietary change to sustain some of the benefits of fasting. The authors (DEZ, EFD) acknowledge the Mulago Foundation, the Horace W.

Abstract
AIM To observe the effect of Ramadan fasting on renal function of people with diabetes. METHODS This prospective, observational, and longitudinal study was conducted at Baqai Institute of Diabetology and Endocrinology, between April-July 2019. People with type2 diabetes mellitus were recruited using convenient sampling. Demographic data along with renal function were recorded before Ramadan. Kidney functions were assessed in those who came for follow up at 6 weeks, 3 months, and a year after Ramadan. RESULTS A total of seventy people with diabetes participated in this study with the mean age of 53.11 ± 8.70 years. A significant decline in eGFR was noted around six weeks post Ramadan with a significant improvement of eGFR at 3 months follow-up. The normalization of kidney functions among the study participants was observed even after one year of Ramadan. CONCLUSION In this study post Ramadan assessment of creatinine clearance showed a significant fall among fasting people with diabetes though remained with in normal limits. Significant improvement and reversal of kidney functions was noted in those who followed within three months' time.

Abstract
AIM Studies on the effect of Ramadan diurnal intermittent fasting (RDIF) on glucometabolic markers have yielded conflicting results. We conducted ameta-analysis to estimate the effect size for changes in glucometabolic markers in healthy, non-athletic Muslims during Ramadan, and to assess the effect of variable covariates using meta-regression. METHODS CINAHL, Cochrane, EBSCOhost, EMBASE, Google Scholar, ProQuest Medical, PubMed/MEDLINE, ScienceDirect, Scopus, and Web of Science databases were searched from date of inceptionto January 2020. The glucometabolic markers analyzed were: fasting glucose (FG), insulin, insulin resistance (HOMA-IR), leptin, and adiponectin. RESULTS We identified seventy-two studies (3134 participants in total) that were conducted in 22 countries between 1982 and 2020. RDIF-induced effect sizes for the glucometabolic markers were: FG (no. of studies K = 61, number of subjects N = 2743, Hedges'g = -0.102, 95% CI: -0.194, -0.01); serum insulin (K = 16, N = 648, Hedges'g = 0.030 95% CI: -0.165, 0.226); HOMA-IR (K = 10, N = 349, Hedges'g = -0.012, 95% CI: -0.274, 0.250); leptin (K = 13, N = 442, Hedges'g = -0.010, 95% CI: -0.243, 0.223); and adiponectin (K = 11, N = 511, Hedges'g = 0.034, 95% CI: -0.227, 0.296). CONCLUSION RDIF imposes no adverse metabolic impacts, and might help in improving some glucometabolic markers in healthy subjects.

[PMID: 32471399 PMCID: PMC7260764 DOI: 10.1186/s12903-020-01139-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Accepted: 05/14/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Ramadan is a month within the Islamic lunar calendar when Muslims are required to fast (abstain from food and drink) during the daytime (from sunrise to sunset) for the entire month. Due to the established connection between fasting and dehydration and acute sialadenitis, the aim of this study is to determine if there is a higher frequency of sialadenitis among the Muslim population during Ramadan than during other months of the year. METHODS We conducted a retrospective study using the medical records of 120 Muslim patients admitted to the emergency room (ER) and diagnosed with acute sialadenitis over a 5-year period at the Baruch Padeh Medical Center, Poriya, and St. Vincent de Paul (French) Hospital, Nazareth, both located in Israel. The study group were Muslim patients, with the aforementioned diagnosis, admitted during Ramadan, while the control group included patients diagnosed with sialadenitis during the rest of the year. We analyzed overall admission frequency as well as descriptive and diagnostic data, including age, sex, gland involved and several blood test results. RESULTS During the month of Ramadan, the admission of Muslims with a diagnosis of acute sialadenitis was more than double that during the other months of the year - a difference that was found to be statistically significant (p = 0.001). Additionally, we found that Ramadan sialadenitis patients had significantly higher leukocyte numbers at admission (p = 0.0085) and, importantly, a significantly higher level of dehydration (blood urea nitrogen (BUN)/creatinine ratio) than non-Ramadan sialadenitis patients (p = 0.0001). CONCLUSION There is evidence that fasting in Ramadan may increase the risk for the development of acute sialadenitis. Our results suggest that this may be the result of dehydration.

Lipids, Lipoprotein Distribution and Nutritional Parameters over the Ramadan Period in Hemodialysis Patients. Nutrients 2019; 11:nu11092225. [PMID: 31540134 PMCID: PMC6769954 DOI: 10.3390/nu11092225] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 09/08/2019] [Accepted: 09/11/2019] [Indexed: 02/05/2023] Open
Abstract
The period of Ramadan (R) is associated with dramatic changes in eating habits involving extended periods of fasting on a daily basis. The current study assessed whether lipids and lipoproteins were impacted during R in chronic hemodialysis (HD) patients. Forty-five subjects in an outpatient dialysis clinic in Saudi Arabia were evaluated for anthropometric and lipid changes on a monthly basis before, during as well as one and two months after R. In addition to routine biochemical measures, anthropometric assessments including hand-grip strength (HGS), mid-arm muscle circumference (MAMC), plasma lipids and lipoproteins were evaluated. Dietary assessment was carried out using 24 h recalls. Over the course of the study, changes in renal-related parameters (creatinine, albumin, Kt/V) were minor, as were changes in plasma lipids. Large high-density lipoproteins (HDLs) and low-density lipoproteins (LDLs) accounted for the majority of their respective lipoproteins and their proportions did not change over the study period. Mean LDL particle diameters were higher during the R period, but the changes over the study period were small. Calorie intake during R (2139 ± 709 kcal/d) was significantly higher than the value noted two month post-R (1755 ± 424 kcal/d) and this was associated with significant increases in protein (69 ± 24 vs. 60 ± 24 g/d) and fat (97 ± 38, vs. 73 ± 35 g/d), respectively. No changes were noted with respect to HGS and MAMC. These data show that for HD patients, the period of R results in temporal or non-significant effects on plasma lipids, despite changes in nutrient intake.

The effects of Ramadan fasting on clinical and biochemical markers among hemodialysis patients: A prospective cohort study. PLoS One 2019; 14:e0218745. [PMID: 31233556 PMCID: PMC6590819 DOI: 10.1371/journal.pone.0218745] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2019] [Accepted: 06/08/2019] [Indexed: 11/30/2022] Open
Abstract
Background Ramadan fasting is compulsory for all healthy adult Muslims. Although sick people are exempted from Ramadan fasting, some patients such as hemodialysis patients prefer to fast during Ramadan. The effect of Ramadan fasting on clinical outcomes and biochemical markers among hemodialysis patients is not clear. The aim of this study was to examine the effects of daily Ramadan fasting and partial Ramadan fasting on key biochemical and clinical markers among hemodialysis patients as compared to hemodialysis patients who chose not to fast during Ramadan. Methods A prospective cohort study of 269 end stage renal disease patients were recruited from the hemodialysis unit in An-Najah National University Hospital, Nablus, Palestine. The participants were divided into three cohorts based on their plans for fasting during Ramadan in May 2018; Ramadan fasting group (RFG), Ramadan partial fasting group (RPFG) and Ramadan not-fasting group (RNFG). Key clinical and biochemical markers were measured before, during and after Ramadan. Results After adjustment for diabetic and hypertension status and other sociodemographic variables, RFG had higher mean inter-dialytic weight gain (IDWG) by 0.62 kg than RNFG (95% confidence interval (CI) 0.26, 0.99). RPFG also had slight increase in mean IDWG than RNFG by 0.35 kg (95% CI 0.11, 0.60). Additionally, RFG and RPFG had significant increase in mean serum potassium as compared to RNFG. Diabetes was independently associated with increased IDWG by 0.48 kg (0.25, 0.72). Diabetes and hypertension were associated with some independent changes in biochemical markers, but these were clinically negligible. Conclusion Our findings suggest that Ramadan fasting (fully or partially) is tolerable by hemodialysis patients and is not associated with important clinical complications. However, these patients should be made aware of the potential risk of fluid overload and hyperkalemia, if they decide to fast during Ramadan. Thus, they should be closely monitored and instructed to adhere to their dietary and fluid intake allowances. Further prospective cohort studies with comprehensive dietary measures and information on adverse clinical outcomes may provide more evidence about the tolerability and safety of Ramadan fasting by hemodialysis patients.

Abstract
Abstract
Objective
We aimed to investigate the effects of Ramadan fasting on renal functions in patients with stage 3 and 4 chronic kidney disease.
Materials and methods
The study was conducted in Ramadan month which was between June and July. Patients were evaluated before Ramadan, the week immediately following the end of the Ramadan, and 3 and 6 months after Ramadan.
Results
Twenty-four fasting (mean age of 68 ± 13 years) and 55 non-fasting individuals (mean age of 69 ± 9 years) were included in this study. There was no statistically significant difference for creatinine levels in the first week after Ramadan in both groups compared to levels before Ramadan (p = 0.070, p = 0.470, respectively). The groups were compared according to the criteria of deterioration in renal function (reduction of 25% in GFR and 30% increase in serum creatinine levels). There were no statistically significant differences between the two groups according to these two criteria (p = 0.452, p = 0.660, respectively). In univariate and multivariate logistic regression analysis, the presence of diabetes mellitus and proteinuria were found to be independent risk determinants of renal dysfunction.
Conclusion
Patients with diabetes mellitus and prominent proteinuria may constitute critical patient groups for renal function deterioration during Ramadan fasting.

Abstract
Background There are controversies over the effects of Ramadan fasting on pregnancy outcomes, and women’s perspectives of fasting are diverse. This study aimed to assess the perspectives and pregnancy outcomes of maternal Ramadan fasting in the second trimester of pregnancy. Methods A case-control study was conducted at Hawler Maternity Teaching Hospital of Erbil, Iraq from October 2017 to January 2018. Out of 301 participating women, 155 fasted during the second trimester of their current pregnancy, while the remaining 146 did not. Mothers were asked concerning their fasting behaviors and perception of fasting during pregnancy. The main outcomes of this study were gestational diabetes, preterm labour, preeclampsia, low birth weight, Apgar score, height, weight, and head circumference of the newborn. Results About 80% of the women in the fasting group fasted for 21–29 days during Ramadan, out of whom 38.7% completed fasting for the entire Ramadan period. The results revealed that the decision to fast during pregnancy was negatively associated with the mother’s educational level and occupation. Weight gain during pregnancy in the fasting women was approximately 0.4 kg less than those who did not fast. The incidence of gestational diabetes was 2.6% in the fasting women, while it was 8.3% in the non-fasting mothers (P = 0.02). Regression analysis showed that women who did not fast during the second trimester of pregnancy were 1.51 times more likely to develop gestational diabetes [odd ratio (OR) 1.51; 95% confidence intervals (CI) 0.06, 0.74, P = 0.01]. It was also found that among the women in the fasting categories, those who fasted for 21–29 days during pregnancy had a lower risk of gestational diabetes compared to the other groups. More than half of the mothers in the fasting group (60%) perceived that fasting during pregnancy was compulsory for healthy and non-healthy women, comparing with those who did not fast. Conclusion It was found that fasting during the second trimester of the pregnancy decreased the risk of gestational diabetes and excessive weight gain during pregnancy. Most of Iraqi women did not fully recognize their right to be exempted from fasting during pregnancy by the Islamic law.

Dietary Practices Adopted by Track-and-Field Athletes: Gluten-Free, Low FODMAP, Vegetarian, and Fasting. Int J Sport Nutr Exerc Metab 2019; 29:236-245.

Abstract
Some track-and-field athletes implement special diets aiming to improve health and/or performance. An evidence-based approach to any diet is recommended to minimize the risks associated with unnecessary dietary restriction, which may potentially do more harm than good. Four prevalent diets are reviewed in this study: (a) gluten-free; (b) low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP); (c) vegetarian; and (d) fasting diets. Recently, gluten-free diets and low FODMAP diets have emerged as novel regimes thought to improve gastrointestinal health and reduce the risk of exercise-associated gastrointestinal symptoms. No direct beneficial outcomes have been associated with avoiding gluten for clinically healthy athletes. Indirectly, a gluten-free diet is associated with other dietary changes, particularly FODMAP reduction, which may improve adverse gastrointestinal symptoms. Vegetarian diets can optimally support athletic demands. However, attention is required to ensure adequate energy and intake of specific nutrients that are less abundant or less well absorbed from plant sources. Finally, fasting is a long-standing concept that is undertaken on a voluntary and obligatory basis. Despite limited supporting research, voluntary fasting is a popular alternative to conventional diets perceptually offering health and body composition benefits. Strict obligatory fasting guidelines likely require the implementation of tailored nutrition strategies to help athletes cope with athletic demands. Overall, a multitude of factors influence adherence to special diets. Even when adherence to a special diet is a necessity, education and advice from an accredited dietitian/nutritionist are recommended for track-and-field athletes to optimize nutrition for health and performance.

Abstract
Studies on disordered eating behaviors (DEB) in multicultural populations with multiple religious/cultural affiliations are needed in order to clarify the relationship between cultural background and DEB. Therefore, we compared the presence of DEB among Christian and Muslim adolescents who share their school environment, controlling for the effect of body mass index, demographic variables and lifestyle habits. A sample of 493 girls and boys (339 Christian, 138 Muslim) whose mean (±SD) age was 14.8 (±1.7) years completed self-reporting questionnaires and underwent measurements of anthropometric data. Religious/cultural affiliation was defined by self-identification. The dependent variable, DEB was assessed by means of the Eating Disorders Inventory (EDI-2). Muslim girls and boys score higher than Christians on EDI-2 total scores, especially on the perfectionism subscale. Bivariate and multivariate analyses were used to determine the characteristics associated with DEB, which were detected in 24% of participants (19% of Christians and in 35% of Muslims). Among girls, DEB were directly associated with overweight or obesity, the presence of frequent quarrels with parents, academic failure and spending more than 3 h a day watching screen images. Among boys, DEB were directly associated with overweight or obesity and Muslim background; and inversely associated with age and socioeconomic status.

Abstract
No previous study has evaluated the effects of RF on inflammatory and hematological indices of COPD patients. The main objective of the present pilot study was to assess the effects of RF on some inflammatory and hematological indices measured in male patients with stable COPD. Fifteen COPD patients (mean ± SD of age: 71 ± 6 years) who fasted during Ramadan 2017 volunteered for the study. Three sessions (Before-Ramadan, End-Ramadan and After-Ramadan) were selected. Spirometry tests and blood samples were consistently performed 2.5-4.5 hr before the interruption of the fasting. Assessment sessions comprised: spirometry, inflammatory [erythrocyte sedimentation rate (ESR); C-reactive protein (CRP)] and hematological [red and white blood cells (RBC, WBC); hemoglobin; hematocrit; mean corpuscular volume; mean corpuscular hemoglobin; platelets] indices. Findings were analyzed by applying Friedman ANOVA. The median (lower-upper quartiles) of ESR (Before-Ramadan: 3 (2-9), End-Ramadan: 7 (0-13), After-Ramadan: 9 (5-15) mm/h) and CRP (Before-Ramadan: 20 (11-38), End-Ramadan: 15 (9-34), After-Ramadan: 20 (12-46) mg/L) were not significantly affected by RF. Among all the hematological indices, RF influenced only hemoglobin (Before-Ramadan: 14.4 ± 2.2, End-Ramadan: 13.4 ± 1.3, After-Ramadan: 12.2 ± 0.9 g/dL), hematocrit (Before-Ramadan: 45 ± 7, End-Ramadan: 40 ± 4, After-Ramadan: 39 ± 4%), RBC (Before-Ramadan: 5.1 ± 1.0, End-Ramadan: 4.6 ± 0.7, After-Ramadan: 4.4 ± 0.5 106/mm3) and WBC (Before-Ramadan: 8,673 ± 1,911, End-Ramadan: 7,840 ± 1,526, After-Ramadan: 9,507 ± 2,190/mm3). Compared to the Before-Ramadan session, the End-Ramadan session values for hemoglobin, hematocrit, RBC and WBC were lower. Compared to the After-Ramadan session, the End-Ramadan session values for hemoglobin and WBC were higher and lower, respectively. In conclusion, RF caused significant reduction in hemoglobin, hematocrit, RBC and WBC. However, it did not induce any significant changes in the CRP and ESR indices.

Abstract
OBJECTIVES To explore the frequency of renal colic (RC) secondary to urinary stones in Ramadan compared to other months and seasons of the year. METHODS Retrospective cross-sectional study using medical records of 237 patients admitted through the emergency room (ER) with a diagnosis of RC secondary to urinary stones over a 10-year period at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia. RESULTS Patients fasting in Ramadan are 2 times more likely to present with a calculus of ureter as opposed to calculus in another location in the urinary tract, particularly when the holy month of Ramadan falls in the summer season. There was no significant difference in the frequency of urinary stones between Ramadan and non-Ramadan months. CONCLUSION Fasting in Ramadan does not increase the risk for developing urinary stones compared to non-fasting months. However, fasting in Ramadan during the summer may increase the risk of developing ureter stones compared to fasting in Ramadan during the winter.

Abstract
Mealtimes and feeding schedules may interfere with the circadian system and impact sleep. The practice of intermittent fasting (IF) in its different formats is increasing worldwide. However, most studies addressing the effect of IF on circadian rhythms, daytime sleepiness, and sleep architecture have been conducted during diurnal IF for Ramadan. In this article, we analyze the effect of diurnal IF on the circadian clock, sleep, and daytime sleepiness. In free-living, unconstrained environments that do not control for lifestyle changes such as sleep/wake schedules, sleep duration, and light exposure, studies have demonstrated sudden and significant delays in bedtime and wake time during diurnal intermittent fasting for Ramadan. However, subsequent studies that accounted for lifestyle factors and sleep/wake patterns have reported no changes in markers of the biological clock, daytime sleepiness, or sleep parameters. Nevertheless, several researchers have demonstrated a reduction in the proportion of rapid eye movement stage sleep as the significant alteration in sleep architecture during fasting.

Abstract
AbstractThe study aimed to examine the effects of diurnal Ramadan fasting (RF) on substrate oxidation, energy production, blood lipids and glucose as well as body composition. Nine healthy Muslim men (fasting (FAST) group) and eight healthy non-practicing men (control (CNT) group) were assessed pre- and post-RF. FAST were additionally assessed at days 10, 20 and 30 of RF in the morning and evening. Body composition was determined by hydrodensitometry, substrate oxidation and energy production by indirect calorimetry, blood metabolic profile by biochemical analyses and energy balance by activity tracker recordings and food log analyses. A significant group×time interaction revealed that chronic RF reduced body mass and adiposity in FAST, without changing lean mass, whereas CNT subjects remained unchanged. In parallel to these findings, a significant main diurnal effect (morning v. evening) of RF on substrate oxidation (a shift towards lipid oxidation) and blood metabolic profile (a decrease in glucose and an increase in total cholesterol and TAG levels, respectively) was observed, which did not vary over the course of the Ramadan. In conclusion, although RF induces diurnal metabolic adjustments (morning v. evening), no carryover effect was observed throughout RF despite the extended daily fasting period (18·0 (sd 0·3) h) and changes in body composition.

Abstract
PURPOSE Studies have shown that experimental fasting can affect cognitive function, sleep, and wakefulness patterns. However, the effects of experimental fasting cannot be generalized to fasting during Ramadan due to its unique characteristics. Therefore, there has been increased interest in studying the effects of fasting during Ramadan on sleep patterns, daytime sleepiness, cognitive function, sleep architecture, and circadian rhythm. METHOD In this review, we critically discuss the current research findings in those areas during the month of Ramadan. RESULTS Available data that controlled for sleep/wake schedule, sleep duration, light exposure, and energy expenditure do not support the notion that Ramadan intermittent fasting increases daytime sleepiness and alters cognitive function. Additionally, recent well-designed studies showed no effect of fasting on circadian rhythms. However, in non-constrained environments that do not control for lifestyle changes, studies have demonstrated sudden and significant delays in bedtime and wake time. CONCLUSIONS Studies that controlled for environmental factors and sleep/wake schedule reported no significant disturbances in sleep architecture. Nevertheless, several studies have consistently reported that the main change in sleep architecture during fasting is a reduction in the proportion of REM sleep.

Abstract
AIMS: We hypothesized that if we control for food composition, caloric intake, light exposure, sleep schedule, and exercise, intermittent fasting would not influence the circadian pattern of melatonin. Therefore, we designed this study to assess the effect of intermittent fasting on the circadian pattern of melatonin. METHODS: Eight healthy volunteers with a mean age of 26.6 ± 4.9 years and body mass index of 23.7 ± 3.5 kg/m2 reported to the Sleep Disorders Center (the laboratory) on four occasions: (1) adaptation, (2) 4 weeks before Ramadan while performing Islamic intermittent fasting for 1 week (fasting outside Ramadan [FOR]), (3) 1 week before Ramadan (nonfasting baseline [BL]), and (4) during the 2nd week of Ramadan while fasting (Ramadan). The plasma levels of melatonin were measured using enzyme-linked immunoassays at 22:00, 02:00, 04:00, 06:00, and 11:00 h. The light exposure, meal composition, energy expenditure, and sleep schedules remained the same while the participants stayed at the laboratory. RESULTS: The melatonin levels followed the same circadian pattern during the three monitoring periods (BL, FOR, and Ramadan). The peak melatonin level was at 02:00 h and the trough level was at 11:00 h in all studied periods. Lower melatonin levels at 22:00 h were found during fasting compared to BL. Cosinor analysis revealed no significant changes in the acrophase of melatonin levels. CONCLUSIONS: In this preliminary report, under controlled conditions of light exposure, meal composition, energy expenditure, and sleep-wake schedules, intermittent fasting has no significant influence on the circadian pattern of melatonin.

Abstract
OBJECTIVE Our aim was to determine how Ramadan fasting effects serum Human NAD-dependent deacetylase sirtuin 1 (SIRT1/SIR2L1) and visfatin levels during pregnancy. MATERIALS AND METHODS Thirty-six patients were included in this case-control study. The patient group consisted of 18 pregnant women who were Ramadan fasting. Another healthy 18 pregnant women with matching pregnancy weeks and ages formed the control group. Blood samples were obtained from the patients for biochemical analyses and serum adipokine level measurements. RESULTS The mean sirtuin and visfatin levels in fasting pregnant women were 2.87 ± 0.95 and 60.18 ± 19.49 ng/mL, respectively, while the mean serum sirtuin and visfatin levels in the control group was determined to be 4.28 ± 1.45 and 23.26 ± 6.18 ng/mL, respectively. A statistically significant difference was determined between the groups (p = 0.002, p = 0.0001). A correlation analysis provided a negative correlation between number of fasting days and sirtuin levels (r = 0.45, p = 0.005) and a positive correlation with visfatin levels (r = 0.73, p = 0.0001). CONCLUSION As a result, while the serum sirtuin 1 level of pregnant women decreased due to fasting in Ramadan, we determined that their visfatin levels increased and this increase was in correlation with the days of fasting.

Abstract
The aim of the present study was to evaluate serum adiponectin, leptin, apelin and omentin levels to explore metabolic changes occurring during fasting in the month of Ramadan. The study was designed as a prospective study. The patients were divided into two groups, each comprising 20 patients: Group I, fasting pregnant women, and Group II, non-fasting pregnant women. The patients' age, parity, gestational week and body mass index were recorded. Adiponectin and omentin levels were significantly lower in fasting pregnant women (p < 0.001). When the two groups were compared in terms of serum leptin and apelin levels, both were found to be significantly higher in Group I than in Group II. The findings of the present study suggest that pregnant women who are willing to fast during 24-38 weeks' gestation should be informed about insulin resistance.

Abstract
SLE is a common autoimmune disease with considerable morbidity. Ramadan fasting is a religious custom Muslims regularly practice. We aimed to evaluate the effect of Ramadan fasting on SLE patients' disease activity, health quality of life and lipid profile. We conducted this case control study as a pilot study in 40 quiescent SLE patients, 21 cases who decided to fast and 19 controls who decided not to have Ramadan fasting between August and November 2009 in lupus unit of Rheumatology Research Center in Tehran University of Medical Sciences, Iran. They were assessed for SLE Disease Activity Index, lipid profile and quality of life with Short-Form 36 (SF-36) Health Survey, 1 day before Ramadan, the day after and 3 months after Ramadan fasting. After 24.1 ± 5.4 (mean ± SD) days of fasting, anti-ds DNA increased for 0.34 ± 0.41 mmol/dL in cases versus 0.07 ± 0.31 in controls (P = 0.026). Likewise C3 increased more dramatically in cases (16.8 ± 17.5 vs. 2.3 ± 13.2 mg/dL, P = 0.006). Three months after fasting, anti-ds DNA was still increased 0.28 ± 0.46 mmol/dL in cases while a 0.02 ± 0.43 mmol/dL drop in controls was detected (P = 0.04). On the contrary, C3 returned to baseline. These changes were not accompanied with significant changes in disease activity and health quality of life. Ramadan fasting had no effect on lipid profile except for delayed total cholesterol decrease in cases in comparison with controls (16.4 ± 29.4 decrease vs. 4.6 ± 23.9 mg/dL decrease, P = 0.018). Ramadan fasting probably has no detrimental effect on SLE patients' disease activity and their quality of life in the quiescent phase of disease.

Abstract
Background Fasting during the month of Ramadan is a religious obligation for Muslims who represent 20% of the world population. This study explores the safety of fasting for a whole month among patients with chronic kidney disease (CKD) with the possible risk of dehydration and hyperviscosity leading to deterioration of kidney functions and vascular thrombosis. Methods We followed CKD patients with stable kidney function who chose to fast during the month of Ramadan. A group of nonfasting CKD patients served as controls. Serum creatinine was recorded at the beginning of the month, after 1 week of fasting, at the end of the month and 3 months later. Patients were followed for major adverse cardiovascular events (MACE). Results A total of 131 CKD patients were recruited and included in two groups: fasting and nonfasting (mean baseline estimated glomerular filtration rate 27.7, SD 13 and 21.5, SD 11.8 mL/min/1.73 m2, respectively). A rise of serum creatinine was noted during fasting in 60.4% of patients by Day 7 and was associated with intake of renin angiotensin aldosterone system antagonists [relative risk (RR) 2, P = 0.002]. Adverse cardiovascular events were observed in six patients in the fasting cohort and were associated with a rise of serum creatinine after 1 week of fasting (P = 0.009) and the presence of pre-existing cardiovascular disease (RR 15, P = 0.001); the latter association was confirmed by logistic regression analysis. Only one event was recorded in the nonfasting group, P = 0.036. Conclusions MACE occurred more frequently among fasting CKD patients with pre-existing cardiovascular disease and were predicted by an early rise of serum creatinine.

Abstract
Background: Fasting has been recently discovered to improve overall health, but its beneficial effects in the presence of hepatic insufficiency have not been proven. Aim: The influence of fasting on the metabolism, immunological aspects, and oxidative stress of 40 male carbon tetrachloride (CCl4)-intoxicated Wistar rats was investigated in the present study. Methods: The rats were divided into four groups, including a placebo group, CCl4-intoxicated rats, which were injected subcutaneously with 1.0 ml/kg of CCl4 solution, a fasting group, which was fasted 12 h/day for 30 days, and a fourth group, which was injected with CCl4 and fasted. Results: The metabolism, immunity, and oxidative stress improved in CCl4-intoxicated rats fasted for 12 h/day for 30 days, as evidenced in significant increase ( p < 0.05) in total protein, globulin, immunoglobulin M (IgM) and IgG levels, and total antioxidant capacity. In contrast, significant decrease ( p < 0.05) in blood glucose, total cholesterol, low-density lipoprotein-cholesterol, alanine aminotransferase, C-reactive protein, and malondialdehyde levels were observed. Compared with CCl4-intoxicated rats, significant differences in the albumin, triacylglycerol, high-density lipoprotein-cholesterol, very low-density lipoprotein-cholesterol, cardiovascular risk factor, calcium and magnesium levels were not detected. Conclusions: The results of the present study showed that fasting improved metabolism, immunity, and oxidative stress in CCl4-intoxicated rats. Thus, fasting during Ramadan is safe for patients with hepatic disorders, as the prophet Mohammed (S) said “Keep the fast, keep your health”.

Abstract
We aimed to assess the effect of Islamic intermittent fasting, during and outside of Ramadan, on plasma levels of leptin and ghrelin while controlling for several potential confounding variables. Eight healthy male volunteers with a mean age of 26.6±4.9 years reported to the sleep disorders center (SDC) at King Saud University on four occasions: 1) adaptation; 2) 4 weeks before Ramadan while performing Islamic fasting for 1 week (baseline fasting) (BLF); 3) 1 week before Ramadan (non-fasting baseline) (BL); and 4) during the second week of Ramadan while fasting. Plasma leptin and ghrelin levels were measured using enzyme-linked immunoassays at 22:00, 02:00, 04:00, 06:00, and 11:00. During BLF, there were significant reductions in plasma leptin concentrations at 22:00 and 02:00 compared with the baseline concentrations (at 22:00: 194.2±177.2 vs. 146.7±174.5; at 02:00: 203.8±189.5 vs. 168.1±178.1; p<0.05). During Ramadan, there was a significant reduction in plasma leptin levels at 22:00 (194.2±177.2 vs. 132.6±130.4, p<0.05). No significant difference in plasma ghrelin concentrations was detected during the BL, BLF, or Ramadan periods. Cosinor analyses of leptin and ghrelin plasma levels revealed no significant changes in the acrophases of the hormones during the three periods. The nocturnal reduction in plasma leptin levels during fasting may be the result of the changes in meal times during fasting.

Abstract
BACKGROUND During Ramadan, Muslims fast throughout daylight hours. There is a direct link between fasting and increasing incidence of infections. Antibiotic usage for treatment of infections should be based on accurate diagnosis, with the correct dose and dosing regimen for the shortest period to avoid bacterial resistance. This study aimed to evaluate the practices of physicians in prescribing suitable antibiotics for fasting patients and the compliance of the patients in using such antibiotics at regular intervals. MATERIALS AND METHODS An observational study was carried out during the middle 10 days of Ramadan 2014 in two pharmacies at Baghdad. A total of 34 prescriptions (Rx) for adults who suffered from infections were examined. For each included Rx, the researchers documented the age and sex of the patient, the diagnosis of the case, and the name of the given antibiotic(s) with dose and frequency of usage. A direct interview with the patient was also done, at which each patient was asked about fasting and if he/she would like to continue fasting during the remaining period of Ramadan. The patient was also asked if the physician asked him/her about fasting before writing the Rx. RESULTS More than two-thirds of participating patients were fasting during Ramadan. Antibiotics were prescribed at a higher percentage by dentists and surgeons, for which a single antibiotic with a twice-daily regimen was the most commonly prescribed by physicians for patients during the Ramadan month. CONCLUSION Physicians fail to take patient fasting status into consideration when prescribing antibiotics for their fasting patients. Antibiotics with a twice-daily regimen are not suitable and best to be avoided for fasting patients in Iraq during Ramadan - especially if it occurs during summer months - to avoid treatment failure and provoking bacterial resistance.

Abstract
Background Ramadan fasting and its attendant lifestyle changes induce changes in the circadian rhythm and in associated physiological and metabolic functions. Previous studies that have assessed psychomotor performance during Ramadan fasting have reported conflicting results. Therefore, we designed this study to objectively assess the effects of intermittent fasting during and outside Ramadan (to control for lifestyle changes) on drowsiness, blink total duration and mean reaction time (MRT) test while controlling for potential confounders. Methods Eight healthy volunteers with a mean age of 25.3 ± 2.9 years and a mean body mass index (BMI) of 23.4 ± 3.2 kg/m2 reported to the sleep laboratory on four occasions for polysomnography (PSG) and drowsiness and psychomotor assessments as follows: 1) adaptation; 2) 4 weeks before Ramadan while performing the Islamic fasting for 1 week (baseline fasting) (BLF); 3) 1 week before Ramadan (non-fasting baseline) (BL); and 4) during the second week of Ramadan while fasting (Ramadan). OPTALERT™ was used to objectively assess daytime drowsiness using the Johns Drowsiness Scale (JDS), and blink total duration and a visual reaction time test were used to assess MRT. Results Rapid eye movement (REM) sleep percentage was significantly lower at BLF (17.7 ± 8.1%) and at Ramadan (18.6 ± 10.7%) compared with BL (25.6 ± 4.8%) (p < 0.05). There were no significant differences between JDS scores and blink total duration during the two test periods in BL, BLF and Ramadan. There were no significant changes in MRT during BL, BLF and Ramadan. Conclusions Under controlled conditions of fixed light/dark exposure, caloric intake, sleep/wake schedule and sleep quality, the Islamic intermittent fasting has no impact on drowsiness and vigilance as measured by the JDS, total blink duration and MRT.

Abstract
Islamic intermittent fasting is distinct from regular voluntary or experimental fasting. We hypothesised that if a regimen of a fixed sleep-wake schedule and a fixed caloric intake is followed during intermittent fasting, the effects of fasting on sleep architecture and daytime sleepiness will be minimal. Therefore, we designed this study to objectively assess the effects of Islamic intermittent fasting on sleep architecture and daytime sleepiness. Eight healthy volunteers reported to the Sleep Disorders Centre on five occasions for polysomnography and multiple sleep latency tests: (1) during adaptation; (2) 3 weeks before Ramadan, after having performed Islamic fasting for 1 week (baseline fasting); (3) 1 week before Ramadan (non-fasting baseline); (4) 2 weeks into Ramadan (Ramadan); and (5) 2 weeks after Ramadan (non-fasting; Recovery). Daytime sleepiness was assessed using the Epworth Sleepiness Scale and the multiple sleep latency test. The participants had a mean age of 26.6 ± 4.9 years, a body mass index of 23.7 ± 3.5 kg m(-2) and an Epworth Sleepiness Scale score of 7.3 ± 2.7. There was no change in weight or the Epworth Sleepiness Scale in the four study periods. The rapid eye movement sleep percentage was significantly lower during fasting. There was no difference in sleep latency, non-rapid eye movement sleep percentage, arousal index and sleep efficiency. The multiple sleep latency test analysis revealed no difference in the sleep latency between the 'non-fasting baseline', 'baseline fasting', 'Ramadan' and 'Recovery' time points. Under conditions of a fixed sleep-wake schedule and a fixed caloric intake, Islamic intermittent fasting results in decreased rapid eye movement sleep with no impact on other sleep stages, the arousal index or daytime sleepiness.

Abstract
OBJECTIVE To investigate whether fasting during Ramadan influences injury incidence in professional Muslim and non-Muslim footballers. DESIGN Prospective cohort study. SETTING Professional First Division League of Qatar. PARTICIPANTS About 527 male football players (462 Muslim and 65 non-Muslim) from 7 league clubs (first year of data collection) and 8 clubs (second and third years). INTERVENTIONS Daily collection of training and match exposure from August 2008 until April 2011 by club medical staff. Injuries during training and match play were recorded on standardized injury cards. MAIN OUTCOME MEASURES Injury incidence was calculated as number of injuries per hour exposed to risk, and expressed as rate per 1000 hours. The probability of injury for different Arabic months between Muslims and non-Muslims was calculated using Generalized Estimating Equations (GEEs). RESULTS There was no significant difference in total, match, and training injury incidence between the Ramadan and non-Ramadan periods. Non-Muslim footballers had a significantly higher injury incidence rate than Muslim footballers both during Ramadan (8.5 vs 4.0 injuries/1000 hours, P = 0.009) and non Ramadan (6.6 vs 4.9 injuries/1000 hours, P = 0.004) periods. The GEE analysis revealed that after adjusting for age and random factors (month and club), the probability of match injury among non-Muslims was the highest in Ramadan and the 2 consecutive following months (adjusted odds ratio of injury among non-Muslims compared with Muslims was 3.7 [95% confidence interval (CI), 1.7-7.9], P = 0.001 during Ramadan (ninth) month; 2.4 (95% CI, 1.1-4.9), P = 0.021 during 10th month; and 2.7 (95% CI, 1.2-5.8), P = 0.013 during 11th month). Finally, there was no change in injury patterns over the months of the Islamic calendar. CONCLUSIONS Ramadan does not impact injury incidence for Muslim footballers in Qatar, suggesting the current adjustments and scheduling of football activities during Ramadan are sufficient. The increased match injury among non-Muslims during and 2 months post-Ramadan may suggest less effective coping strategies.

Abstract
Introduction: The Muslim population worldwide have a higher incidence of cardiovascular disease than that of the non-Muslim population, and this may become exaggerated during the religious observances of Ramadan. This review assessed the evidence regarding the impact of Ramadan on lifestyle behaviours in Muslims with cardiovascular disease. Method: This article reviews the literature concerning the impact of Ramadan on lifestyle behaviours and its effects on cardiac rehabilitation between 2000 and 2012. Studies were identified, using Academic Search Complete, Google Scholar, PsycInfo, PsycARTICLES, Medline and CINAHL Plus. The search terms used were: ‘cardiac rehabilitation’; ‘cardiovascular disease’; ‘Ramadan’; ‘fasting’; ‘physical activity’; ‘exercise’; ‘diet’; ‘smoking’; ‘sleep’; ‘behaviour change’; ‘medication’; and ‘treatment’. Findings: Evidence suggests that fasting during Ramadan can have a beneficial effect on factors such as cholesterol levels, body weight and blood pressure; however, benefits are rarely sustained in the long term. Other behavioural changes such as non-adherence to medication, and diet and exercise regimes have more negative consequences for sufferers of cardiac disease. Conclusions: Lifestyle behaviours adopted during Ramadan can have a negative impact on cardiovascular disease. Health professionals are urged to find innovative ways to engage this population in healthy lifestyle choices throughout this period.

Attarzadeh Hosseini SR, Sardar MA, Hejazi K, Farahati S. The effect of ramadan fasting and physical activity on body composition, serum osmolarity levels and some parameters of electrolytes in females. Int J Endocrinol Metab 2013; 11:88-94. [PMID: 23825979 PMCID: PMC3693661 DOI: 10.5812/ijem.9602] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2012] [Revised: 02/01/2013] [Accepted: 02/03/2013] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND So far, there have been a few and incoherent results about the effects of physical activities. Fasting in Ramadan has an effect on the level of osmolarity and the concentration of serum electrolytes both in active and inactive females. OBJECTIVES The aim of this study was to observe the changes of serum electrolytes and osmolarity levels according to regular exercise during fasting. PATIENTS AND METHODS TWENTY TWO HEALTHY FEMALES WHO WERE ELECTED BY CONVENIENCE SAMPLING METHOD WERE DIVIDED INTO TWO GROUPS: 1) fasting + exercise (FE; n = 11) and 2) fasting + non exercise (FNE; n = 15). The FE group participated in aerobic training for four sessions per week during the fasting. All measurements were done once before the first day, on the second week, on the fourth week and two weeks after fasting month and these measures were used to analyze test results. RESULTS THE MEAN DIFFERENCES WERE AS FOLLOWS: significant weight loss, BMI, WHR, in two groups at the end of Ramadan (P < 0.05). The mean of weight, BMI, WHR, body fat, protein, mineral and total water showed no difference between groups (P > 0.05). Potassium, creatinine, urea and uric acid had been decreased significantly in both groups (P < 0.05). Variance between groups was significant only in variable urea (P < 0.05). Variations within group had been changed in FBS; sodium, phosphorus and osmolarity levels were not changed significantly. CONCLUSIONS According to this result, regular exercise in case of fasting in Ramadan led to some changes in serum osmolarity index, electrolytes and water. Therefore, it is important for female athletes to consider applying a suitable nutritious diet and sufficient water consumption during Ramadan.

Effects of ramadan fasting on biochemical and anthropometric parameters in physically active men. Asian J Sports Med 2012; 2:134-44. [PMID: 22375232 PMCID: PMC3289216 DOI: 10.5812/asjsm.34775] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2011] [Accepted: 05/20/2011] [Indexed: 11/25/2022] Open
Abstract
Purpose The aim of this study was to assess the effects of Ramadan fasting on several biochemical and anthropometric parameters in physically active men by comparing fasters and nonfasters before, during, and after Ramadan. Methods Eighteen physically active men (10 fasters and 8 nonfasters) participated in this study. Subjects visited the laboratory for a total of four sessions on the following occasions: three days before Ramadan (Bef-R), the 15th day of Ramadan (Mid-R), the 29th day of Ramadan (End-R), and 21 days after Ramadan (Post-R). During each session, subjects underwent anthropometric measurements, completed a dietary questionnaire and provided a fasting blood sample. Results Body weight and body fat percentage decreased in fasters by 1.9% (P<0.001) and 6.2% (P=0.003), respectively, but increased in nonfasters by 2.2% (P<0.001) and 10.2% (P=0.001), respectively, from Bef-R to End-R. Fasters’ hematocrit and hemoglobin increased by 5.3% (P<0.001) and 6.3% (P=0.01), respectively, from Bef-R to End-R, while neither of these parameters changed in nonfasters. Fasters experienced an increase in the following parameters from Bef-R to End-R: urea (8.7%; P<0.001), creatinine (7.5%; P<0.001), uric acid (12.7%; P<0.001), serum sodium (1.9%; P<0.001), serum chloride (2.6%; P<0.001) and high-density lipoprotein cholesterol (27.3%; P<0.001). Of these parameters, only creatinine increased (4.4%; P=0.01) in nonfasters. Conclusion We conclude that Ramadan fasting lowers body weight and body fat percentage and can elevate high-density lipoprotein cholesterol in physically active men. However, practicing aerobic exercise during a hot and humid Ramadan month can induce a state of dehydration marked by an increase in some renal function markers and serum electrolytes.

Abstract
Purpose Muslim athletes may continue training and competing while they are fasting. There is a concern about negative effects of fasting on sports performance. This study aimed to investigate the influence of two training time frames on athletes’ body composition and performance during Ramadan fasting. Methods An observational study was conducted and thirty four male volunteer athletes from different sports including volleyball, karate, taekwondo and football were assigned in two groups. The first group included 14 elite athletes who during Ramadan voluntarily participated in training sessions at 1 hour before Iftar (BI) and the second group of 20 elite athletes who during Ramadan participated in training sessions at 3 hours after Iftar (AI). Testing was performed one week before; in the first and fourth weeks of Ramadan and one week after Ramadan. Weights, heights and skinfold thickness were assessed at each time point and body mass index was calculated. Each player was assessed for agility and explosive strength as well. Results The mean weight and body mass index of both groups decreased significantly during Ramadan (P<0.001). Performance variables were not negatively affected by fasting in BI or AI group athletes. Conclusions Weight reduction might come with either BI or AI training schedules in Ramadan. Daytime or evening training did not inversely affect the agility and power performances in a group of elite athletes during Ramadan fasting.

Abstract
Sleep has preoccupied and fascinated many civilizations since the dawn of mankind. Here, we critically review the various elements pertaining to sleep in the context of early Islamic religion and culture. The many principles of sleep hygiene, wellbeing and health associated with adequate sleep, and the understanding of sleep as a dynamic state are all apparent from such explorative process of Islamic tradition.

Abstract
Each year, many pregnant Muslim women fast during Ramadan. Using Indonesian cross-sectional data and building upon work of Almond and Mazumder (2011), I show that people who were prenatally exposed to Ramadan fasting have a poorer general health than others. As predicted by medical theory, this effect is especially pronounced among older people, who also more often report symptoms indicative of coronary heart problems and type 2 diabetes. Among exposed Muslims the share of males is lower, which is most likely caused by death before birth. I show that these effects are unlikely the result of common health shocks correlated to the occurrence of Ramadan, or of fasting mainly occurring among women who would have had unhealthier children anyway.

Abstract
Calorie restriction (CR) has been promoted to increase longevity. Previous studies have indicated that CR can negatively affect mood and therefore the effect of CR on mood and quality of life (QOL) becomes crucial when considering the feasibility of CR in humans. We conducted a three month clinical trial on CR (reduction of 300 to 500 kcal/day) combined with two days/week of Muslim sunnah fasting (FCR) to determine the effectiveness of FCR on QOL among aging men in Klang Valley, Malaysia. A total of 25 healthy Malay men (age 58.8±5.1 years), with no chronic diseases and a BMI of 23.0 to 29.9 kg/m2 were randomized to FCR (n=12) and control (n=13) groups. Body composition measurements and QOL questionnaires were ascertained at baseline, week 6 and week 12. QOL was measured using the Short-Form 36, sleep quality was determined using the Pittsburgh Sleep Quality Index, the Beck Depression Inventory II was used to measure mood and the Perceived Stress Scale was used to measure depression. The FCR group had a significant reduction in body weight, BMI, body fat percentage and depression (P<0.05). The energy component of QOL was significantly increased in FCR group (p<0.05). There were no significant changes in sleep quality and stress level between the groups as a result of the intervention. In conclusion, FCR resulted in body weight and fat loss and alleviated depression with some improvement in the QOL in our study and has the potential to be implemented on a wider scale.

Abstract
We hypothesize that factors other than a sudden shift in eating habits contribute to delay of circadian rhythms during Ramadan. We assessed circadian changes during a baseline period (BL, 1 week before Ramadan), the first week (R1), and the second week (R2), of Ramadan, in six healthy Muslim young adults using portable armband physiological and activity sensor devices. All participants lived in an unconstrained environment and showed delayed sleep phase syndrome, so that they normally slept during the day and ate at night. During Ramadan, there was a further delay in the acrophase of skin temperature during Ramadan, indicating a shift in the circadian pattern of body temperature. Additionally, there was a delay in the peak of energy expenditure during R1 and R2. These results support our hypothesis that in addition to sudden shift in meal times, other factors may affect the sleep pattern and circadian rhythms during Ramadan.

Abstract
Experimental fasting has been shown to alter the sleep-wakefulness pattern in various species. As fasting during Ramadan is distinct from experimental fasting, the physiological and behavioural changes occurring during Ramadan fasting may differ from those occurring during experimental fasting. There has been increased interest in recent years in sleep changes and daytime sleepiness during Ramadan. Moreover, many of those who fast during Ramadan associate this fasting with increased daytime sleepiness and decreased performance. This raises the question of whether Ramadan fasting affects sleep. In this review, we discuss the findings of research conducted to assess changes in sleep pattern, chronobiology, circadian rhythms, daytime sleepiness and function and sleep architecture during the month of Ramadan. Where applicable, these findings are compared with those obtained during experimental fasting.
