“…Attention estimated by the digit cancellation test was significantly lower at DR in comparison with BR and AR; this supports the results of Boukhris et al [ 11 ], who reported that Ramadan observance had an adverse effect on attention. Also, supporting previous literature [ 4 , 5 , 11 ], the impaired sleep reported in DR could be related to a decrement in cognitive performance, such as an attention task. Indeed, there was a significant increase in total scores on the PSQI and the subjective sleep quality scores DR in comparison with BR, with a significant decrease of sleep duration in DR compared to BR.…”

Ramadan observance is characterized by several changes in behaviors, such as food and sleep, which could affect physical and cognitive performance. The aim of the present study was to investigate the effects of a 35-min nap (N35) opportunity on physical performance during the 5-m shuttle run test (5mSRT); attention; feelings; mood states; and perceptual measures of stress, fatigue, and muscle soreness during Ramadan observance. Fourteen physically active men (22 ± 3 years, 177 ± 4 cm, 76 ± 5 kg) were tested after a no-nap condition (N0), N35 15 days before Ramadan (BR), the last 10 days of Ramadan (DR), and 20 days after Ramadan (AR). Measures included the digit cancellation test (attention estimation), the profile of mood state (POMS), and the Hooper questionnaires. After a 5-min standard warm-up, participants performed the 5mSRT (6 × 30 s with 35 s in between; best distance (BD), total distance (TD), and fatigue index (FI) were recorded), along with the rating of perceived exertion (RPE) after each test repetition. After the 5mSRT test, participants responded to the feeling scale (FS). The results showed that TD and FI during the 5mSRT were not affected by Ramadan observance. However, BD was significantly lower than DR compared to AR after N0 (∆ = −4.3 ± 1.3%; p < 0.01) and N35 (∆ = −2.6 ± 1.0%; p < 0.05). After N0, attention decreased significantly at DR in comparison with BR (p < 0.05) and AR (p < 0.001). BD and TD improved after N35 compared to N0 at BR (∆ = +4.4 ± 2.1%, p < 0.05 for BD and ∆ = +4.8 ± 1.6%, p < 0.01 for TD), DR (∆ = +7.1 ± 2.2%, p < 0.05 for BD and ∆ = +5.1 ± 1.6%, p < 0.01 for TD), and AR (∆ = +5.5 ± 1.5%, p < 0.01 for BD and ∆ = +5.2 ± 1.2%, p < 0.001 for TD). A significant increase in attention was observed after N35 in comparison with N0 at DR (p < 0.01) and AR (p < 0.01). However, no changes were found for the perception of mood states, stress, sleep, muscle soreness, and the FI during the 5mSRT. Also, N35 was better than N0 for RPE at DR (p < 0.05), feelings at AR (p < 0.05), and fatigue estimation at AR (p < 0.01). A 35-min nap opportunity may have beneficial effects on physical and cognitive performances before, during, and after Ramadan.

“…Changes in eating schedules as well as other activities (i.e., late prayer ( Taraweeh )) have considerable effects on sleep [ 4 , 5 , 6 , 7 ] and food/fluid intakes [ 8 , 9 ]. Other changes may also be observed during this month [ 10 , 11 ].…”

Association of husbands' education status with unintended pregnancy in their wives in southern Ethiopia: A cross-sectional study

et al. 2020

Background Unintended pregnancy rates are substantially higher in developing regions, have significant health consequences, and disproportionately affect subgroups with socioeconomic disadvantage. We aimed to examine whether there is an association between husbands' education status and their wives unintended pregnancy in southern Ethiopia. Methods The data source for this study was from a cross-sectional study on iron-folate supplementation and compliance in Wolaita, South Ethiopia. Data were collected from October to November 2015 in 627 married pregnant women regarding their husbands' education status, socio-demographic characteristics, and if they wanted to become pregnant at the time of survey using an interviewer administered questionnaire. Logistic regression was used to estimate Odds Ratios (ORs) with associated z-tests and 95% Confidence Intervals (95% CI) for variables associated with unintended pregnancy. Results The proportion of unintended pregnancy in this sample was 20.6%. Husbands' education status, age, residence, and using family planning methods were associated with unintended pregnancy (all P-values < 0.05). Multivariable models consistently showed that being married to a husband with at least some college or university education was associated with a decreased OR for unintended pregnancy after controlling for age and use of family planning at conception period (OR 0.36 [95%CI: 0.17, 0.82]) and age and rural residence (OR 0.40 [95%CI: 0.18, 0.90]).

“…The risks of adverse effects are greater in those with medical conditions such as kidney disease who choose to fast during the month of Ramadan. Moreover, most of the existing bodies of research on hydration levels during RF suggested that healthy people who are observing the month of Ramadan have to ensure that they have an adequate fluid intake during the non-fasting period [17,43,123,124]. Furthermore, it has previously been observed that if dehydration took place during the fasting hours in Ramadan, there is an association with an increased incidence of migraine headache, dizziness, and fatigues, particularly among employees who are working for long hours and in hot weather [125].…”

Background: Ramadan is a sacred month in Islam, which involves 29–30 days of dawn-till-dusk dry-fasting. Millions of Muslims observed Ramadan fasting (RF) this year in the midst of the COVID-19 pandemic. Certain ethnic groups worldwide, including Muslims, have been disproportionately affected by COVID-19, raising fears that fasting could bring additional health risks. This directly impacted on the current challenges faced by health professionals. The COVID-19 virus is expected to become seasonal. Therefore, the evidence presented in this review is valid beyond Ramadan as intermittent fasting is practiced more widely, irrespective of religion, throughout the year as a therapeutic and prophylactic means for several conditions. Methods: A wide range of literature databases were searched for the effects of RF and intermittent fasting on human health and then linked to COVID-19 impact to generate the evidence. Results: This review presents a body of evidence proving RF is safe and beneficial for healthy people who adopt a balanced diet, drink plenty of fluids, and engage in regular physical activity. Fasting reduces levels of pro-inflammatory cytokines (IL-1β and IL-6), which are associated with severe COVID-19. Furthermore, increased handwashing and hygiene during Ramadan may reduce infection risks. For some, social isolation, physical inactivity, reduced access to food and stress – linked to the pandemic – may minimize the benefits that is achieved during a “normal” Ramadan. Conclusions: RF during the COVID-19 pandemic is not a cause of concern for healthy people. However, people who are ill are exempt from fasting and should seek medical advice if they wish to fast. RF during the COVID-19 pandemic is a unique experience and future research will reveal its impact on human health.
