Purpose In Indonesia, 29.3% of Indonesian women were obese. Dehydrated women have 1.6 times higher risk of becoming obese than normal ones. This study was aimed to further explore the association between gestational weight gain (GWG) and maternal hydration status. Design/methodology/approach This longitudinal study involved 50 pregnant women aged 18–35 years. Subject identity, age, parity and household expenses were collected using questionnaire. Urine specific gravity (USG) was used as an indicator for hydration status. Venous blood was collected to measured haemoglobin (Hb) by anemometer method. Anthropometric data such as pre-pregnancy weight, maternal body weight, GWG, body mass index (BMI) and mid-upper arm circumference (MUAC) was collected using standardized tools. Dietary and total water intake (TWI) were measured through three consecutive days of a 24-h food recall. Pearson’s correlation, independent t-test and analysis of covariance were used to appraise the hypothesis. Findings The subject’s mean age was 29.3 ± 5.6 years; BMI was 23.5 ± 4.1 kg/m2. MUAC (28.2 ± 4.0 cm) and Hb (11.5 ± 1.0 g/dl) were still in the normal range. Most subjects were well hydrated, with an average USG of 1.016 g/mL. GWG and TWI are significantly correlated (p < 0.01). Based on the hydration status, after corrected with TWI, GWG was not significantly different. Originality/value It calls to mind that nutrition and water intake, alongside weight gain monitoring during pregnancy, are part of an effort to prevent pregnancy risks.

Purpose This paper aims to design to evaluate the protective effect of vitamin E to ameliorate the disturbances in testosterone pathway and sperm quality of male rats induced by the glycosides vicine (V) and convicine (C) of Vicia faba. Design/methodology/approach Forty male albino rats were divided into five equal groups; control, paraffin oil, V (400 mg/kg) C (150 mg/kg)-treated group, vitamin E (100 mg/kg) + VC-treated group, and vitamin E (200 mg/kg) + VC-treated groups which injected intraperioneally (IP) with 0.5-ml saline, 0.5-ml paraffin oil,V (400 mg/kg) and C (150 mg/kg) of Vicia faba, vitamin E (100 mg/kg) + VC-treated groups, and Vitamin E(200 mg/kg) + VC-treated groups, respectively. Blood and testicular tissue were obtained after one month of the study. The male genital organs were calculated. Testosterone (Ts), luteinizing hormone (LH), follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEA-SO4), sex hormone binding globulin (SHBG),?-glutamyl transpeptidase (?-GT), glucose-6-phosphate dehydrogenase (G6PD), 3ß-hydroxysteroid dehydrogenase (3ßHSD), lactate dehydrogenase (LDH), spermatozoa concentration, percent of mortality and abnormal sperms were evaluated. Findings The VC-treated group showed significant decrease (p < 0.01) in Ts, DHEA-SO4, G6PD, spermatozoa number and mortality percent, as well as, the male genital organs (testes, epidydemis, seminal vesicle, prostate and vasa deferentia) while significant increase (p < 0.01) was found in LH, FSH, SHBG, LDH, ?-GT, sperms monoclonal Ki-67, and abnormal spermatocytes levels compared with control group. Vitamin E co-injection with VC-treated group returned all these parameters to the normal values. The higher dose of vitamin E (200 mg/kg) was more effect than the lower dose (100 mg/kg). Originality/value Vicia faba contains V and C glycosides. The V and C glycosides in Vicia faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The V and C glycosides induced disturbances in testosterone pathway and sperm quality of male rats and vitamin E ameliorates these disturbances.

Purpose This study aims to investigate the association between vitamin D measured in serum 25 hydroxyvitamin D [25(OH)D] and outcomes of COVID-19 patients in Bahrain. This paper hypothesized that lower serum 25(OH)D concentration in COVID 19 patients is associated with longer viral clearance time (VCT) and higher risk of admission to the intensive care unit (ICU). Design/methodology/approach This study used a retrospective cohort design of patients admitted to Salmaniya Medical Complex, Manama, Kingdom of Bahrain, from February to June 2020. This study included patients with positive, confirmed COVID-19 diagnosis made using reverse transcription-polymerase chain reaction (RT-PCR), World Health Organization diagnosis manual and local diagnostic guidelines. Primary outcome measures were: VCT measured as the time in days between the first positive RT-PCR test result and the first of two consecutive negative RT-PCR results on recovery and admission need to ICU. Findings A total of 450 patients were analyzed; mean age was 46.4 ± 12.4 years and 349 (78%) were men. Mean 25(OH)D concentration was 41.7 ± 23.7 nmol/L for the entire sample. Severe vitamin D deficiency (<25 nmol/L) was present in 20%, mild-to-moderate deficiency (25–50 nmol/L) in 55%, insufficiency (50 to <75 nmol/L) in 18% and sufficiency (=75 nmol/L) in 7%. The mean VCT was 12.9 ± 8.2 days. Multivariate linear regression analysis showed that severe vitamin D deficiency was associated with longer VCT, with an average of three extra days after correction for age and sex (β = 3.1; p = 0.001). Multinomial regression analysis showed that vitamin D deficiency was associated with an 83% increased risk of admission to ICU after correction for age and sex (odds ratio = 1.8; p = 0.03). Originality/value The results showed that severe vitamin D deficiency was associated with longer recovery time from COVID-19. Low serum 25(OH)D is associated with increased need for critical care in an ICU. Large-scale randomized controlled trials are necessary to further investigate the complex association between vitamin D and COVID-19 infection.

Purpose Understanding humans’ food intake practices is helpful in reducing health problems. The purpose of this study was to investigate the relationships between eating behaviours and binge eating and to examine the influence of sex and weight status on these relationships. Design/methodology/approach A total of seventy-eight participants (39 with overweight; mean age: 38.1 ± 6.3 years; body mass index [BMI]: 25 ± 5.7 kg/m2) underwent measurements of binge eating, eating styles and body compositions. A hierarchical multiple regression analysis was performed to predict binge eating as a function of eating styles and demographic variables. Findings Women presented higher levels of binge eating symptomatology and emotional eating than men. The analysis showed that age and gender did not emerge as important predictors of binge eating. In contrast, emotional and external eating and BMI were found to be important predictors of binge eating. The results indicate that higher emotional and external eating behaviour with higher BMI are important risk factors for binge eating in a non-clinical sample. Originality/value In this study, BMI was used as a causal factor rather than a consequence of deregulation of eating behaviour. An individual’s tendency to binge eat may be determined by BMI, emotional eating and sensitivity to environmental food stimuli. Understanding sex differences and causal relationships between eating behaviours is critical for the prevention and treatment of obesity and related health problems and for proper dietary management.

Purpose Previous studies have reported that dietary fibers such as polydextrose and maltodextrin can reduce food intake; however, the studies on the differences of this effect are insufficient. The purpose of this paper is to compare the effects of dietary fibers maltodextrin and polydextrose on alterations of short-term satiety, energy intake and postprandial blood glucose in healthy females. Design/methodology/approach This study was designed as a randomized, crossover and double blind research. For this purpose, 21 healthy females consumed a milkshake containing 0 g (control), 15 g polydextrose (PDX) and 15 g maltodextrin (MDX), and an ad libitum lunch meal was served 150 min later. Subjective appetite scores (hunger, satiety, prospective food consumption and desire to eat) were measured using a visual analog scale. Appetite scores and blood glucose were measured before preload and once per 15 min after milkshake consumption. Findings Visual analog scale scores showed that PDX had an improved effect on satiety and hunger feelings. Compared to the control, dietary fiber increased the Area Under Curve (AUC) scores of satiety (p < 0.001) and decreased the AUC scores of hunger (p < 0.001), prospective food consumption (p < 0.001) and desire to eat (p < 0.001). Energy intake during ad libitum meal was significantly lower in PDX (Control: 862 (54.3) Kcal versus PDX: 679 (35.4) Kcal and MDX: 780 (49.3) Kcal. Moreover, the blood glucose levels were significantly lower in MDX. Originality/value This study conducted with healthy females demonstrated that PDX was more effective in inducing satiety during subsequent food intake, and that postprandial blood glucose were within more healthy levels in MDX.

Purpose The high prevalence of hypertension is a significant concern worldwide. A decrease in salt intake is a well-known strategy to control hypertension and reduce the risk of cardiovascular diseases. Little is known about the factors influencing salt intake behaviors in settings such as Iran where consumption of salt is higher than the recommended amount. The purpose of this study was to find out what factors affect three salt intake behaviors among women: adding salt when cooking, adding salt to prepared food at the table and purchasing salty foods. Design/methodology/approach A community-wide cross-sectional survey of 516 women was conducted in Ilam, Iran. Participants were recruited using the cluster random sampling method. The survey included behaviors and variables of an expanded theory of planned behavior. The hypothesized relationships were investigated using structural equation modeling. Findings Perceived behavioral control (PBC) (p < 0.001) and habit (p = 0.01) appeared to be significant factors of adding salt when cooking. Determinants of adding salt to food at the table were intention (p < 0.001), PBC (p < 0.001), habit (p < 0.001). Also, PBC (p < 0.001), intention (p < 0.001), habit (p < 0.001) were identified as predictors of the purchase of salty foods. The results did not support the moderating role of Hedonic feeling to salt on the relation between intention and behaviors. Originality/value This study would be applicable to develop salt reduction interventions. Because altering the hedonic response to food is difficult, the lack of its moderating role could be a promising finding for developing salt reduction interventions.

Purpose This study aims to identify the effect of selected agro-industrial factors associated with the olive oil phenolic composition, total phenolic content (TPC), antioxidant capacity and oxidative stability index (OSI). The study also aims to assess the relationship between the quality indices and each of the individual phenol, TPC, antioxidant capacity and OSI. Design/methodology/approach Olive oil samples (n=108) were collected from Lebanese northern (Akkar and Zgharta-Koura) and southern (Hasbaya and Jezzine) regions, at three harvesting times (early, intermediate, late) and using different types of mills (traditional, sinolea, two- and three-phase decanters). The samples were analyzed using official standard methods. Findings The highest TPC, antioxidant capacity and OSI were obtained in early harvested olive oil, using two-phase decanters for TPC and three-phase decanters for antioxidant capacity and OSI. A prediction model, including the free acidity, K232, TPC, C18:2, C18:0, tyrosol and apigenin, was obtained; it allowed to predict very highly significantly the OSI (p < 0.001). Apigenin, tyrosol and C18:2 recorded the highest standardized coefficients (ß^+= 0.35) and thus had the highest influence on OSI. As per antioxidant capacity of olive oil, another very highly statistically significant prediction model was constructed (p < 0.001). It included only two predictors, oleacein and TPC, with the latter having the most influence (ß^+= 0.37). Originality/value The overall results highlighted the detrimental effects of agro-industrial factors on olive oil chemical composition, and this contributes significantly to improve olive oil’s quality and characteristics, which are important for the product economical and nutritional values.

Purpose This study aimed to analyze the lipid content and fatty acid composition in the liver and muscle of a porcupinefish species inhabiting waters around the Ryukyu Islands to investigate their potential as a source of long-chain n-3 polyunsaturated fatty acids (LC-PUFAs). Design/methodology/approach Porcupinefish were collected along the Okinawa Island coast. The composition of fatty acids and cholesterol in both liver and muscle were analyzed using a gas chromatograph mass spectrometer. Findings The liver of Okinawan long-spine porcupinefish was rich in lipids whose content correlated to the proportion of liver/body weight. Fatty acid compositions in their liver and muscles were similar to each other. LC-PUFAs occupied 44% of total fatty acids, with docosahexaenoic acid (DHA) being the dominant (42%), whereas eicosapentaenoic acid occupied 2.4%. The liver contained 1,690 mg of cholesterol and 14.8 g of DHA per 100 g, whose proportion decreased in summer compared to other seasons (p = 0.036). Originality/value The liver of Okinawan long-spine porcupinefish, which has not yet been commercially used although its non-toxicity is claimed, can be an excellent source of LC-PUFAs, especially DHA, accentuating its potential in food supplements’ production.

Purpose The purpose of this paper is to develop and validate the Greek version of the Mediterranean Diet Adherence Screener (MEDAS). Design/methodology/approach The MEDAS was translated to the Greek language forward and backward, twice and subsequently was administered to 50 healthy adult participants living in Attica, Greece. The participants had to complete the tool twice, within a period of 15 days. Participants also completed the well-recognized Mediterranean Diet Score (MedDietScore), for comparison purposes with the tested tool. Socioeconomic and anthropometric characteristics were also assessed. Findings There was a moderate association between the Greek MEDAS (MEDAS-Gr) and the MedDietScore [(Pearson r = 0.50, p < 0.001; Intraclass Correlation Coefficient (ICC)=0.46, p = 0.015)]. The concordance between these two questionnaires varied between the items (Intraclass correlation coefficient of 0.62 for fruit at the highest and −0.09 for alcohol consumption). The Cronbach’s a coefficient of reliability for the Greek MEDAS was good (a = 0.62). The two administrations of the MEDAS-Gr produced similar mean total scores (7.6 vs 7.9, p = 0.090), which were correlated (r = 0.71, p < 0.001; ICC = 0.85, p < 0.001) and agreed substantially [k statistic (k)=0.72, 95% CI 0.54–0.89, p < 0.001)]. Originality/value The MEDAS-Gr seems to be a valid tool for assessing adherence to the Mediterranean diet in the Greek population.

PurposeEstablished data revealed a relationship between obesity and increasing the risk of mortality and morbidity of chronic diseases. There are conflicting data regarding the association between adherence of Dietary Approach to Stop Hypertension (DASH) and obesity. Therefore, this study intends to investigate this relationship among a large sample of Iranian adults.MethodsThis cross-sectional study was performed by 10693 individuals; in the urban population: Yazd Health Study (n=6750), and in the suburb region: Shahedieh cohort study (n=3943). Dietary intake was evaluated by using a validated Food Frequency Questionnaire (FFQ). In all participants, anthropometric indices including body mass index were measured. The DASH score was considered utilizing gender-specific quintiles of DASH items. To evaluate the relationship of DASH diet and obesity, multivariate logistic regression analysis was used.ResultsBy adjusting confounders, participants in highest quintiles of DASH diet compared to the lowest have lower odds of obesity in suburb area (OR: 0.78; 95% CI: 0.63, 0.96), in urban (OR: 0.71; 95% CI: 0.52, 0.99), and in whole population of both studies (OR: 0.75; 95% CI: 0.63, 0.90). Besides, more compliance of women to this diet in urban (OR: 0.64; 95% CI: 0.48, 0.85) and population of both studies (OR: 0.77; 95% CI: 0.62, 0.96) were associated with reduced odds of central obesity. ConclusionsDASH dietary pattern could decrease odds of obesity in both urban and suburb area, and central obesity in urban area only. Further prospective studies are needed for causal conclusion.
