A prospective study of the effect of fasting during the month of Ramadan on depression and diabetes distress in people with type 2 diabetes

Effects of Modified Ramadan Fasting on Mental Well-Being and Biomarkers in Healthy Adult Muslims - A Randomised Controlled Trial

BACKGROUND

Ramadan fasting has seen increased attention in research, often with inconsistent findings. This study aims to investigate whether dietary and lifestyle modifications during Ramadan can improve well-being and health in healthy adult Muslims.

METHOD

A randomised controlled trial with two parallel groups was conducted in an outpatient clinic of a university hospital in Essen, Germany, in 2016. Healthy adult Muslims (n = 114) aged 18-60 years were randomised to a modified fasting group; i.e., they received educational material prompting dietary and lifestyle modifications pre-Ramadan, and a control group who undertook Ramadan fasting as usual. Primary outcome was quality of life (WHO-5 Well-Being Index). Secondary outcomes included sleep quality, spirituality, and mindfulness (all self-report), body weight, body mass index, body fat, waist circumference, hip circumference, blood pressure, and heart rate, as well as blood serum biomarkers. Safety was examined via adverse events.

RESULTS

The modified fasting group reported significantly higher quality of life (WHO-5) compared to the control after Ramadan (MD 5.9; 95% CI, 0.02-11.8; p < 0.05). Group differences in favour of the modified fasting were also found for satisfaction with health (MD 5.9, 95% CI 0.19-11.67), ease of life (MD 4.1, 95% CI 0.38-7.80) and mindfulness (MD 7.6, 95% CI 2.68-12.52), reductions in weight (MD, - 0.9 kg; 95% CI - 1.39 to - 0.42), BMI (MD - 0.3 kg/m2, 95% CI - 0.50 to - 0.15), hip circumference (MD - 0.3 kg/m2, 95% CI - 0.50 to - 0.15), and diastolic blood pressure (MD - 2.8 mmHg, 95% CI - 5.15 to - 0.43). About 60% of participants reported adverse events, mostly headaches/migraines, dizziness/fatigue, common cold, and gastrointestinal symptoms, with no group differences. One serious non-related adverse event each occurred in both groups.

CONCLUSION

Pre-Ramadan dietary and lifestyle advice can lead to short-term improvements in mental and physical well-being of adult Muslims observing Ramadan. As such, this study demonstrates the potential benefits of culturally appropriate health interventions in a religious context.

Perceived changes in the mental well-being among Nigerians due to Ramadan Intermittent Fasting during the COVID-19 pandemic

INTRODUCTION

Muslims fast every year during the month of Ramadan from dawn until dusk. This study examined mental well-being and correlating factors among Nigerian adults who observed Ramadan intermittent fasting (RIF).

METHODS

A validated generalized anxiety disorder-2 and Patient Health Questionnaire-2, the four-item spiritual well-being index, and the Islamic intrinsic religiosity questionnaire were used to collect data about mental well-being (depression, anxiety), spirituality, and intrinsic religiosity through a web-based survey between the May 9, 2021 (27th of Ramadan, 1442) and the June 4, 2021 (29th of Shawwal, 1442). We studied the mental well-being of respondents over a period of 4 weeks before Ramadan (BR) and during the 4 weeks of Ramadan between the April 12, 2021 and the May 12, 2021(DR). Multinomial regression analysis was used to determine the factors associated with depression and anxiety. This research did not receive any grant or funding.

RESULTS

A total of 770 adult Nigerians who observed RIF study were included in this cross-sectional study. When compared to mental well-being BR, observing RIF by Nigerian adult respondents was associated with a significant improvement in their mental well-being. A higher proportion of respondents felt less depressed DR (61.3% vs. 56.5%. < .001). Interest and pleasure in doing things improved DR than BR (p= 0.007) and respondents felt less nervous and anxious (60.7% vs. 57.1%, respectively; p <.001). Mental well-being was independently associated with sociodemographic characteristics, physical activity, and perceived relationships.

CONCLUSIONS

This study found significant improvement in mental well-being DR compared to BR despite the ongoing COVID-19 pandemic. The effect of RIF on mental well-being needs further research with multicentric studies among different sets of ethnic populations.

The effect of Ramadan on elderly patients presenting to the emergency department

Background Patients visiting the emergency department (ED) may show variations by certain time periods such as Ramadan. We wished to ascertain whether Ramadan affects the ED presentations, clinical conditions and outcomes of patients aged 65 years or older. Methods . Patients aged 65 years or older who presented to ED in Ramadan and in the following month in 2018 were reviewed retrospectively. Results . A total of 1947 patients were enrolled, of whom 958 presented in Ramadan and 989 in the following month. The patients who presented in Ramadan most commonly (23.8%) presented between 8 p.m. and 11.59 p.m.; patients who presented in the following month most commonly (24%) presented between 8 a.m. and 11.59 a.m. (p=0.26). Complaints concerning the central nervous system (CNS) were more common in the month after Ramadan (p<0.0001). Diagnoses related to the cardiovascular system were more commonly made in Ramadan (p=0.037), whereas those related to CNS, otorhinolaryngology and oncology were more commonly made in the following month (p=0.0005, p=0.024 and p=0.003, respectively). No significant difference was found between the two groups with respect to outcomes (p=0.36). Compared to patients who presented in Ramadan, those that presented in the following month had a significantly longer ED stay (p=0.036). Conclusion . Our study detected no significant difference between the two groups with respect to the time of presentation and ED outcomes. Patients who presented in Ramadan had a lower incidence of CNS complaints; a higher incidence of cardiovascular diagnoses; lower incidences of CNS, oncological and otorhinolaryngological diagnoses and a significantly shorter length of ED stay.

Does intermittent fasting impact mental disorders? A systematic review with meta-analysis

Accumulating evidence supports the benefits of intermittent fasting (IF) as a dietary strategy for cardiometabolic health and weight control. However, little is known about the potential implications of IF on mental disorders. The aim of this review was to synthesize evidence regarding the effects of IF on mental disorders (depression, anxiety, and mood state) in the general population. We conducted a systematic search in five databases from inception to January 2022. Randomized and nonrandomized clinical trials (RCTs/nonRCTs) were included. A random effects method was used to pool standardized mean differences (SMDs) and 95% CIs. A total of 14 studies involving 562 individuals were included, of which 8 were RCTs and 6 were nonRCTs. IF showed a moderate and positive effect on depression scores when compared to control groups (SMD: 0.41; 95%CI: 0.05 to 0.76; I2=45%; n = 4). Conversely, within-group analyses did not show any significant effect of IF on anxiety (SMD: 0.10; 95%CI: -0.09 to 0.30; I2=0%; n = 5) or mood state (SMD: 0.14; 95%CI: -0.09 to 0.37; I2=59%; n = 7). IF modalities did not negatively impact mental disorders in the general population. In fact, IF showed a positive influence on diminishing depression scores, and did not modify anxiety or mood.

Prevalence and correlates of diabetes distress and depressive symptoms among individuals with type-2 diabetes mellitus during Ramadan fasting: A cross-sectional study in Bangladesh amid the COVID-19

AIMS

Psychological concerns relating to "diabetes distress" (DD) and depressive symptoms (DS) in individuals with type-2 diabetes mellitus (T2DM) may negatively impact adherence to medical treatments and overall mental health. Thus, this study was undertaken to investigate DS and DD in relation to fasting during the month of Ramadan.

METHODS

A cross-sectional survey was conducted among 735 patients with T2DM in 2021. DD and DS were measured by the Problem Areas in Diabetes scale and Patient Health Questionnaire-9, respectively. Logistic regression and correlation analyses were executed.

RESULTS

More than one-third of the participants (41.2%) had DD and DS (36.9%). DS was significantly higher in participants who did not fast (p = 0.027). Participants who had higher dietary diversity were less likely to have DD (p = 0.004) and DS (p = 0.001). Females (AOR = 1.89, 95% CI: 1.25-2.85) and those who lived alone (AOR = 1.89, 95% CI: 1.25-2.85) were more likely to have DS. Participants with diabetes-related complications were more likely to experience DS (AOR = 2.17; 95% CI: 1.5-3.13) and DD (AOR = 3.46; 95% CI: 2.42-4.95). DD was also associated with being younger (p = 0.003), having hypertension (p = 0.030), having heart disease (p = 0.012), and taking insulin (p = 0.010).

CONCLUSIONS

Individuals with T2DM who were not fasting experienced more mental health concerns. Psychosocial support and other interventions from health professionals should be examined and empirical interventions should be implemented to promote the mental health and well-being of individuals with T2DM.

Diabetes and Ramadan: Practical guidelines 2021

Fasting during Ramadan is one of the five pillars of Islam and is obligatory for all healthy Muslims from the age of puberty. Though individuals with some illness and serious medical conditions, including some people with diabetes, can be exempted from fasting, many will fast anyway. It is of paramount importance that people with diabetes that fast are given the appropriate guidance and receive proper care. The International Diabetes Federation (IDF) and Diabetes and Ramadan (DaR) International Alliance have come together to provide a substantial update to the previous guidelines. This update includes key information on fasting during Ramadan with type 1 diabetes, the management of diabetes in people of elderly ages and pregnant women, the effects of Ramadan on one's mental wellbeing, changes to the risk of macrovascular and microvascular complications, and areas of future research. The IDF-DAR Diabetes and Ramadan Practical Guidelines 2021 seek to improve upon the awareness, knowledge and management of diabetes during Ramadan, and to provide real-world recommendations to health professionals and the people with diabetes who choose to fast.

Ramadan Fasting and Maternal and Fetal Outcomes in Pregnant Women with Diabetes Mellitus: Literature Review

There is an emerging Muslim and diabetic population in the United States and other Western countries and majority of pregnant women and patients with diabetes mellitus choose to fast during Ramadan. Fasting during Ramadan in pregnant women with diabetes may represent a 'perfect storm' of metabolic disturbances including hyperglycemia, hypoglycemia and ketosis. Recent continuous and flash glucose monitoring data suggests increased glycemic variability (fasting hypo- and post-Iftar hyperglycemia) in non-pregnant patients with diabetes during Ramadan. Only five small-scale studies, predominantly focused on women with gestational diabetes mellitus in Muslim-majority nations have explored maternal glycemic outcomes during Ramadan which is associated with lower mean blood glucose levels and higher frequency of fasting hypoglycemia. Data is limited however on important clinical outcomes such as symptomatic and serious hypoglycemia requiring hospitalization. Results have been conflicting regarding maternal Ramadan fasting and association with fetal outcomes in women without diabetes. Only one recently published study reported on perinatal outcomes in pregnant women with gestational diabetes which found no effect of Ramadan exposure on mean birthweight or macrosomia frequency but lower neonatal hypoglycemia prevalence, however a significant limitation was lack of documentation of maternal fasting status. At this stage, due to paucity of data, the current medical recommendation is against Ramadan fasting for pregnant Muslim women with diabetes. Large-scale population-based studies are warranted regarding maternal and fetal outcomes in pregnant fasting women with diabetes and such studies should characterize maternal fasting status and have meaningful and consistent clinical outcomes. High-quality data derived from these studies can assist clinicians in providing more evidence-based advice to safely navigate both mother and fetus through a potentially challenging pregnancy.

Fasting Interventions for Stress, Anxiety and Depressive Symptoms: A Systematic Review and Meta-Analysis

Background. Fasting interventions have shown effectiveness in alleviating stress, anxiety and depressive symptoms. However, no quantitative analysis has been carried out thus far. The objective was to determine the effectiveness of fasting interventions on stress, anxiety and depression and if these interventions were associated with increased or decreased fatigue/energy. Methods. Overall, 11 studies and 1436 participants were included in the quantitative analyses. Results. After limiting analyses to randomized controlled trials with low risk of bias, we found that fasting groups had lower anxiety (b = −0.508, p = 0.038), depression levels (b= −0.281, p = 0.012) and body mass index compared to controls without increased fatigue. There was no publication bias and no heterogeneity for these results. These interventions were safe, even in patients with type 2 diabetes. Conclusions. These results should be taken with a caveat. These results are preliminary and encouraging and fasting appears to be a safe intervention. Data are not sufficient to recommend one fasting intervention more than the others. No study was carried out in psychiatric populations and further trials should be carried out in these populations that may be good candidates for fasting interventions.

Ramadan fasting and diabetes 2019: The year in review

INTRODUCTION

The literature on health aspects of Ramadan fasting is widely spread in many journals making it not readily available to those interested in the subject.

MATERIALS AND METHODS

A narrative, non-systematic review of the international literature from two major online databases (viz. Scopus, PubMed) in one year (2019). The search term "Ramadan fasting AND Diabetes" was used, and relevant literature was narrated in a concise thematic account.

RESULTS

Research design included qualitative, quantitative, and mixed methods. Articles included controlled trials, critical appraisals, literature narrations, and systematic reviews, and meta-analyses. The publications spanned a vast array of topics related to Ramadan fasting, including assessments of current safety and efficacy profiles of newer diabetes therapies, modes of insulin delivery, and utilization of advanced technology for the treatment and monitoring of blood glucose during Ramadan fasting. Increased interest was particularly evident in capturing the experience element manifested by perceptions, attitudes, and practices of both patients and healthcare professionals during Ramadan. The current literature consolidates previous data on the safety of fasting practices amongst the well-controlled. On the other hand, it emphasizes the need for more aggressive interventions for high-risk patients, promoting the usage of newer anti-diabetic agents and advanced glucose monitoring technology for safer fasting practices.

CONCLUSIONS

The volume of global literature production related to Ramadan fasting and Diabetes remains modest. Observational studies of small size prevail. Greater improvements in both quality and quantity of research on Ramadan are needed.

The Epidemiology of Depression and Diabetes Distress in Type 2 Diabetes in Kuwait

This study is aimed at describing the prevalence of and risk factors for depression and diabetes distress in people with type 2 diabetes and whether depression and distress are independently associated with worse biomedical outcomes. The study was of cross-sectional design. The setting was the Dasman Diabetes Institute, Kuwait. The Patient Health Questionnaire-9 (PHQ-9) was used to measure the prevalence of depression, defined as a score ≥ 10 (depression caseness). The Problem Areas in Diabetes (PAID) was used to measure diabetes-related distress. Data on biomedical outcomes, lifestyle factors, and sociodemographic information were collected. The prevalence of depression and diabetes distress caseness was 29% and 14%, respectively. Depression caseness patients were more likely to be female (60%; p = 0.001), have Kuwaiti nationality (68%, p = 0.121), were on insulin (67%, p = 0.001), have higher body mass index (p = 0.047), were less physically active (78%; p = 0.034), have a higher PAID score (p < 0.001), and have hypertension (74%, p = 0.047). After adjustment of sociodemographics (age, gender, and marital status) and body mass index, the prevalence of depression was associated with higher HbA1c (B = 0.04, 95% confidence interval 0.01 to 0.60), while diabetes distress had a weak association with HbA1c (B = 0.13, 95% confidence interval 0.04 to 0.22). In conclusion, people with type 2 diabetes in Kuwait have a high prevalence of depression but lower diabetes distress and this was associated with worse glycaemic control.
