Ramadan Fasting: Perception and maternal outcomes during Pregnancy

Consensus recommendations on fasting during Ramadan for patients with kidney disease: review of available evidence and a call for action (RaK Initiative)

Ramadan fasting (RF) involves abstaining from food and drink during daylight hours; it is obligatory for all healthy Muslims from the age of puberty. Although sick individuals are exempt from fasting, many will fast anyway. This article explores the impact of RF on individuals with kidney diseases through a comprehensive review of existing literature and consensus recommendations. This study was conducted by a multidisciplinary panel of experts.The recommendations aim to provide a structured approach to assess and manage fasting during Ramadan for patients with kidney diseases, empowering both healthcare providers and patients to make informed decisions while considering their unique circumstances.

Effects of Ramadan fasting on fetal health: A systematic review

BACKGROUND

Ramadan fasting (RF) is mandatory for all healthy Muslims in the ninth month of the Islamic calendar. Although pregnant women are exempt from fasting, many make the decision to practise it. Concerns that fasting during pregnancy harms the fetus remain, as there are no firm recommendations regarding its safety.

OBJECTIVES

To provide a systematic review on the effects of RF on fetal health.

SEARCH STRATEGY

We conducted a literature search for peer-reviewed articles through Ovid MEDLINE, PubMed, SCOPUS, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) until 31 December 2021.

SELECTION CRITERIA

All case-control and observational cohort studies that reported on fetal outcomes of pregnant women who underwent RF for at least one day during pregnancy are included.

DATA COLLECTION AND ANALYSIS

Two researchers independently reviewed the eligibility of all studies. A third researcher resolved any conflict between researchers. Findings are extracted from eligible papers and presented as narratives.

MAIN RESULTS

Fourteen articles are included based on eligibility criteria, with a total sample size of 2889. Studies demonstrate negative associations between RF and neonatal weight, amniotic fluid index, preterm birth and growth parameters mainly during the second and third trimesters. However, the evidence is not strongly supported.

CONCLUSION

There is limited data to elucidate the relationship between RF and fetal health, hence the need for more studies to provide a better understanding.

Maternal and perinatal outcome of Ramadan fasting in women with gestational diabetes

Objective

To compare maternal and perinatal outcome of Ramadan fasting during pregnancy in women with/without gestational diabetes.

Methods

This prospective case-control study was conducted at Department of Obstetrics & Gynecology Unit 1 Ruth PKM Civil Hospital & Dow Medical College and Holy Family Hospital, Karachi during 1st April to 31st July, 2022. In this study normoglycemic pregnant women and those identified as gestational diabetes (n=52) on oral glucose tolerance test, who fasted during Ramadan were included. Women, on diet control or diet plus metformin were included in the study. Study questionnaire included demographic details, days of fasting, self-reported hypoglycemic episodes. Maternal outcomes included preterm birth, pregnancy induced hypertension. Perinatal outcome included hyperbilirubinemia, hypoglycemia, weight of placenta, and apgar score.

Result

Eighty two women were included in the study, gestational diabetes (n=57) and normoglycemic (n=25). Average days of fasting were 16 ±9.0 days (range 5-30). Women with GDM were older (28.6 vs. 26.0 years, p-value=0.034), had raised levels of HbA1c (5.5 vs. 5.1, p-value=0.004), mean FBS (102.8 vs. 84.6 mg/dl, p-value <0.001), mean RBS (135.3 vs. 106.4 mg/dl, p-value <0.001) and had higher BMI at delivery (31.0 vs. 26.6 kg/m2, p-value=0.004). HbA1c (p-value=0.016) and head circumference of baby (p-value=0.038) were found lower in the group who fasted for more than 20 days among normoglycemic pregnant women. No other maternal and neonatal outcomes were found to be significantly affected by Ramadan fasting among pregnant women with/without GDM.

Conclusion

Gestational diabetes do not affect maternal and perinatal outcome among pregnant women.

Chrononutrition during Pregnancy and Its Association with Maternal and Offspring Outcomes: A Systematic Review and Meta-Analysis of Ramadan and Non-Ramadan Studies

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.

Ramadan Fasting as a Religious Obligation: A Qualitative Study on Opinions and Experiences of Muslim Pregnant Women about Fasting in Turkey

The aim of this study was to examine opinions and experiences of Muslim pregnant women about Ramadan fasting in Turkey. The study had a descriptive, phenomenological design and included 17 Muslim pregnant women living in Turkey. Content analysis and word cloud analysis were performed. The content analysis revealed two themes. The most frequent words in the word cloud analysis were fasting, pregnancy, Ramadan, fast, religious duty, health, observing a missed fast, relief, concern, baby, thirsty and hungry. The findings of the study showed that religious beliefs, experiences, family and society pressured the pregnant women to keep Ramadan fasts. However, due to feeling worried about their own physical and psychological health and their infants, some of the women did not go on a fast. It can be recommended that pregnant women wanting to keep their fasts should be offered information about possible risks of fasting.

Ramadan Fasting in Health and Disease in 2021: A Narrative Review

Introduction: The literature on the health aspects of Ramadan fasting (RF) is widely spread in many journals.

Materials and Methods: This is a narrative review of data obtained from the PubMed database (National Library of Medicine, Bethesda, Maryland, United States). We used the search term “Ramadan fasting,” and relevant records were examined. The publications are narrated thematically.

Results: The publications spanned fundamental, clinical, professional, cultural, and advocacy facets. The publications crossed conventional disciplinary lines and geographical locations and appeared in journals with different access systems. The contents are presented under the themes that emerged depending on the retrieved literature. This year basic coverage included changes in physiology and nutrition during Ramadan. However, the clinical issues included a wide range of topics. These included the impact of RF on nonalcoholic fatty liver disease and adjustments needed in endocrine replacement therapy for hypothyroidism and adrenal insufficiency. Coverage also included chronic kidney disease. The impact on maternal health, fetal well-being, and long-term effects of RF exposures were addressed in several studies. Studies in cardiovascular medicine focused on blood pressure and cardiovascular risk factors. Sports medicine and athletes' well-being received somewhat prominent coverage. The impact on renal function, particularly in patients with chronic kidney disease, was investigated by a few authors. Several groups addressed the eyes' structure and function, neurological conditions, especially headache disorders, and hematological and oncological conditions. Finally, the impact of RF on several aspects of mental health and well-being was addressed by various groups.

Conclusions: Health aspects of RF received a sustained academic interest with a broad spectrum in 2021. This narration provides an overview of the year's scholarly health-related literature on various aspects of health and disease. It should help researchers and clinicians catch up quickly with the health concerns during Ramadan.
