Article Nutritional, Sleep, Physical Activity, and Quality-of-Life Changes during Ramadan Fasting: A Prospective Comparative Study(Frontiers Media SA, 2026) Bayraktaroglu, Emre; Erdem, Nihal Zekiye; Mizrak, Elif; Oner Sayar, Canel; Karaagac, Rabia Melda; Gecgil Demir, Eftal; Tarakci Filiz, Nadide GizemBackground: Ramadan is the holiest month in the Islamic calendar. Ramadan fasting, which lasts from sunrise to sunset, significantly affects eating habits, physical activity, daytime sleepiness, and quality of life. In this study, body weight, daytime sleepiness (Epworth Sleepiness Scale), physical activity level, dietary intake, and quality of life (SF-36) were assessed in fasting and non-fasting individuals before, during, and after Ramadan. Methods: In this prospective longitudinal comparative study of 282 healthy adults, individuals were divided into fasting and non-fasting groups. Data were collected in four phases: 1 week before, in the middle, at the end, and 2 weeks after Ramadan. Results: Total energy intake, macronutrient consumption, and body weight decreased during Ramadan and increased again after Ramadan, with these changes being more pronounced in the fasting group. Daytime sleepiness increased and physical activity level decreased in fasting individuals during Ramadan, but both returned toward baseline levels after Ramadan. In terms of quality of life, significant differences between fasting and non-fasting individuals were observed, particularly in physical and emotional role functioning domains (p < 0.05). Conclusion: This study demonstrated that Ramadan fasting is associated with changes in dietary intake, daytime sleepiness, physical activity, and quality of life. Moreover, similar patterns observed in non-fasting individuals suggest that environmental and lifestyle factors during Ramadan may also play a role.Article Citation - WoS: 6Citation - Scopus: 7Respiratory Muscle Endurance in Obesity Hypoventilation Syndrome(Daedalus Enterprises inc, 2022) Dusgun, Elif Sena; Aslan, Goksen Kuran; Abanoz, Ebru Seker; Kiyan, EsenBACKGROUND: An increase in respiratory work load and resistance to respiration cause a decrease in respiratory muscle endurance (RME) in patients with obesity hypoventilation syndrome (OHS). We aimed to evaluate and compare RME in subjects with OHS and a control group using an incremental load test and compare the RME of subjects with OHS in whom noninvasive ventilation (NIV) was and was not used. METHODS: Forty subjects with OHS (divided according to body mass index [BMI] as group I: 30-40 kg/m(2); and group II: 6 40 kg/m(2)) and 20 subjects with obesity (control group: 30-40 kg/m(2)) were included in the study. RME was evaluated using the incremental load test, and respiratory muscle strength (RMS) was evaluated using mouth pressure measurements. The 6-min walk test, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), EQ-5D Health-Related Quality of Life Questionnaire (EQ-5D), and the Obesity and Weight-Loss Quality of Life Instrument (OWLQOL) were performed. RESULTS: RME and RMS (%) in group I were lower than the control group (P=.001, P=.005, and P=.001, respectively). No significant difference was found between the 3 groups in terms of 6-min walk distance (6MWD) percentage predicted values (P=.98). RME in the NIV user group was higher than the non-user group (P 5.006). ESS, total PSQI, and FSS scores in the control group were less than group I (P=.01, P=.009, and P=.005, respectively) and group II (P 5.01, P <.001, and P <.001, respectively). The EQ-5D scores of the control group were higher than group II only (P=.005 and P=.005, respectively). There were no differences in OWLQOL between the groups (P=.053). CONCLUSIONS: RME was low in subjects with OHS but higher in those who used NIV. The incremental load test could be performed easily and safely in a clinic setting.
