Mental and Behavioural Responses to Bahá'í Fasting: Looking behind the Scenes of a Religiously Motivated Intermittent Fast Using a Mixed Methods Approach.

BACKGROUND/OBJECTIVE: Historically, fasting has been practiced not only for medical but also for religious reasons. Bahá'ís follow an annual religious intermittent dry fast of 19 days. We inquired into motivation behind and subjective health impacts of Bahá'í fasting. METHODS: A convergent parallel mixed methods design was embedded in a clinical single arm observational study. Semi-structured individual interviews were conducted before (n = 7), during (n = 8), and after fasting (n = 8). Three months after the fasting period, two focus group interviews were conducted (n = 5/n = 3). A total of 146 Bahá'í volunteers answered an online survey at five time points before, during, and after fasting. RESULTS: Fasting was found to play a central role for the religiosity of interviewees, implying changes in daily structures, spending time alone, engaging in religious practices, and experiencing social belonging. Results show an increase in mindfulness and well-being, which were accompanied by behavioural changes and experiences of self-efficacy and inner freedom. Survey scores point to an increase in mindfulness and well-being during fasting, while stress, anxiety, and fatigue decreased. Mindfulness remained elevated even three months after the fast. CONCLUSION: Bahá'í fasting seems to enhance participants' mindfulness and well-being, lowering stress levels and reducing fatigue. Some of these effects lasted more than three months after fasting.

Effects of Daytime Dry Fasting on Hydration, Glucose Metabolism and Circadian Phase: A Prospective Exploratory Cohort Study in Bahá'í Volunteers.

Background: Religiously motivated Bahá'í fasting (BF) is a form of intermittent dry fasting celebrated by abstaining from food and drinks during daylight hours every year in March for 19 consecutive days. Aim: To test the safety and effects of BF on hydration, metabolism, and the circadian clock. Methods: Thirty-four healthy Bahá'í volunteers (15 women) participated in this prospective, exploratory cohort study. Laboratory examinations were carried out in four study visits: before fasting (V0), in the third week of fasting (V1) as well as 3 weeks (V3) and 3 months (V4) after fasting. Data collection included blood and urine samples, anthropometric measurements and bioelectrical impedance analysis. At V0 and V1, 24- and 12-hour urine and serum osmolality were measured. At V0-V2, alterations in the circadian clock phase were monitored in 16 participants. Our study was augmented by an additional survey with 144 healthy Bahá'í volunteers filling out questionnaires and with subgroups attending metabolic measurements (n = 11) and qualitative interviews (n = 13), the results of which will be published separately. Results: Exploratory data analysis revealed that serum osmolality (n = 34, p < 0.001) and 24-hour urine osmolality (n = 34, p = 0.003) decreased during daytime fasting but remained largely within the physiological range and returned to pre-fasting levels during night hours. BMI (body mass index), total body fat mass, and resting metabolic rate decreased during fasting (n = 34, p < 0.001), while body cell mass and body water appeared unchanged. The circadian phase estimated by transcript biomarkers of blood monocytes advanced by 1.1 h (n = 16, p < 0.005) during fasting and returned to pre-fasting values 3 weeks after fasting. Most observed changes were not detectable anymore 3 months after fasting. Conclusions: Results indicate that BF (Bahá'í fasting) is safe, has no negative effects on hydration, can improve fat metabolism and can cause transient phase shifts of circadian rhythms.

Bullying Experience among Adolescents with a Turkish Migration Background in Germany: Ethnic Class Composition, Integration, and Religiosity as Protective Factors?

Bullying is a worldwide problem that has serious effects on the mental health of both victims and perpetrators. Although bullying seems related to increasing globalization and migration, it has seldom been researched in this context. This exploratory study examined bullying experiences and related depressive symptoms among a sample of adolescents with a Turkish migration background in a German school context (N = 103, 56.7% female, MAge = 16.17, SDAge = 1.36). The study focuses on three migration-related variables as potentially salutogenic factors: Ethnic class composition, acculturation, and religiosity. While the ethnic class composition did not show any effect, an integration acculturation strategy and religiosity proved to be protective factors against bullying experience. The negative prediction of integration on depressive symptoms was not consistent throughout the multivariate analyses. The results are discussed against the background of new impulses for bullying intervention programs for this vulnerable group of adolescents from a Turkish migration background.
