    As we know, drinking young coconut water and eating the tender meat give many benefit
    to the body for its nutritious value rather than its taste; but do we realize that it requires a
    dangerous tasks in processing it. The process of trimming requires skills which only can
    be obtained by those who run the work daily. Thus, a portable apparatus which has the
    capabilities of reducing the hazardous tasks and fasten the time consumed for processing
    the young coconut fruit has been proposed and developed. The development of the product
    begins with collecting and analyzing the data of 30 young coconut fruits. Then, it is followed
    by designing the whole product at main and component level. The conceptual design is
    done initially using freehand sketching technique. Next, the 3D solid modeling relies
    totally on the CATIA V5R19 software. Finally, a complete details drawing is produced
    using CAD software. In this work, the design focuses on the blade slicing and punch bit
    head to reduce the hazardous tasks during processing of the young coconut. The blade is
    designed to allow the slicing movement to be maneuvered during the husk removal process.
    Meanwhile, the puncher has replaced the usage of chopper in creating an opening at the top
    of the endocarp. Thus, the device developed will reduce the hazardous task by eliminating
    the chopping process and replacing it with the slicing process. Therefore, the tendency to
    get caught in accidental injury during the chopping process can be significantly reduced.

    Disordered eating is prevalent among university students, especially females. Whilst literature suggests that factors associated with disordered eating may differ according to gender, such an association has not been studied in Malaysia. This cross-sectional study aims to compare factors associated with disordered eating between male and female university students. A total of 716 university students (male: 27.4%; female: 72.6%) were recruited in Kuala Lumpur and Selangor, Malaysia. All participants completed a set of self-administered questionnaires and their body weight and height were recorded. About one in five of the university students (20.3%) were found to have disordered eating. There were more female students (22.9%) disordered eating compared to males (13.3%, χ² = 8.16, p < 0.05). In male students (β = 0.228, p < 0.01), depressive symptoms were the only significant predictor for disordered eating. In females, the strongest predictor was depressive symptoms (β = 0.214, p < 0.001), followed by body size satisfaction (β = -0.145, p < 0.01) and body appreciation (β = -0.101, p < 0.05). These findings suggest that there are gender differences in the factors associated with disordered eating among Malaysian university students. Intervention programmes that address disordered eating should take into account these sex differences and its contributing factors.

    Due to its beneficial components, such as glycyrrhizin, licorice is regarded a medicinal and fragrant plant. This research was designed to investigate the efficacy of licorice essential oil as an alternative to chemical antibiotics on broiler production, carcass features, cellular and humoral safety, and numerous biochemical variables in broiler blood serum. A total of 160 day-old broiler chicks were assigned to four treatment groups using a totally randomized approach. Each treatment consisted of 4 replicates, with 10 chicks in each replication. The experimental treatments included a control group, a group receiving an elemental diet containing 0.1% licorice essential oil, a group receiving an elemental diet containing 0.2% licorice essential oil, and a group receiving an elemental diet containing 0.3% licorice essential oil. Broilers had ad libitum access to feed and water in accordance with a three-phase feeding schedule consisting of a starter, grower, and finisher diet. There was no statistically significant difference (P>0.05) in body weight, feed intake, or feed conversion ratio between birds given the control or essential oil licorice at various stages of the experiment. However, birds receiving 0.1% licorice essential oil had a lower gallbladder relative weight and 0.3% licorice essential oil had less abdominal fat than the control group (P<0.05). Blood glucose, cholesterol, and LDL concentrations all fell considerably in licorice essential oil-treated birds relative to controls (P<0.05). The cellular immune response of birds fed licorice-containing diets did not differ from that of control birds (P>0.05), however there was a significant difference in the humoral immune response at 0.1% licorice essential oil compared to the control group (P<0.05). In overall, the results of this experiment demonstrated that incorporating licorice essential oil into a bird's diet improves its health and safety.

    BACKGROUND: Lifestyle changes in Saudi Arabia have affected the dietary intake of adolescents, who now consume more unhealthy foods.

    AIMS: We assessed the dietary intake of female Saudi Arabian adolescents living in Arar.

    METHOD: In this randomised cluster study, female students were selected randomly from assigned schools to form the intervention (n = 68) and control (n = 70) groups. Initially, a 60-minute seminar was held for mothers of students in the intervention group. Subsequently, 6 90-minute sessions were held over 3 months for the intervention group on topics such as food groups, healthy and unhealthy eating, body image and physical activity. The data were analysed using generalized estimating equations.

    RESULTS: The interaction effect (group by time) between the groups revealed statistically significant differences for dairy products (P < 0.001), sweetened beverages (P < 0.001), sweetened baked goods (P = 0.022) and fruits and vegetables (P < 0.003). The intervention significantly increased the intake of dairy products (P < 0.001) and fruits and vegetables (P = 0.003). It reduced the intake of sweetened beverages (P < 0.001) and sweetened baked goods (P = 0.010) in the intervention group.

    CONCLUSION: This intervention showed a grater positive effect on the intervention than the control group; it increased dietary intake of dairy products, fruits and vegetables, and reduced intake of sweetened beverages and sweetened baked goods among the intervention group participants. We recommend similar nutrition interventions among other young Saudi Arabian population groups to prevent obesity and other diseases.

    OBJECTIVE: The purpose of this investigation was to examine change in risk for eating disorders in higher education students sojourning in the United Kingdom (UK), as well as associations between such risk and experiences in the host culture.

    METHOD: Participants were 98 female students from Malaysia, who completed a measure of risk factors for eating disorder symptomatology (the Eating Disorder Inventory-3 subscales of drive for thinness, body dissatisfaction, and bulimia symptoms) at two time points: two months prior to beginning their sojourn in the UK (Time 1) and four months after the sojourn began (Time 2). At Time 2, participants also completed measures of sociocultural adjustment, cultural distance between home and host cultures, and perceived discrimination in the host culture.

    RESULTS: Analyses indicated that, compared to scores at Time 1, participants had significantly higher drive for thinness (d = 0.64), body dissatisfaction (d = 0.54), and bulimia symptoms (d = 0.29) at Time 2. Poorer sociocultural adjustment and greater perceived discrimination significantly predicted greater risk of eating disorders at Time 2.

    DISCUSSION: The stress associated with culture change may place sojourning students at risk for disordered eating. Further research is needed to determine the extent to which this risk is related to culture-change specifically, as opposed to a general set of factors associated with transition-related psychopathology more broadly. © 2016 Wiley Periodicals, Inc.

    OBJECTIVE: The aim of the study was to identify the ethnic differences in dietary patterns and its association with socio-economic, dietary and lifestyle practices among adolescents in Kelantan, Malaysia.

    METHODS: A population-based study of 454 adolescents aged 12 to 19 years was included. A validated food frequency questionnaire was used to assess dietary patterns and three dietary patterns were identified based on the principal component analysis method.

    RESULTS: Malay adolescents had significantly higher scores for the Western-based food pattern and local-based food pattern, whereas Chinese adolescents showed higher scores for the healthy-based food pattern. Multivariate analyses show that age and physical activity (PA) levels were positively associated with healthy-based food pattern in Malay (All, p < 0.001), whereas higher consumption of eating-out from home (EatOut) (p = 0.014) and fast food (p = 0.041) were negatively associated. High weekly breakfast skipping (p < 0.001) and EatOut (p = 0.003) were positively associated with a Western-based pattern, whereas age (p < 0.001) and household income (p = 0.005) were negatively associated. Higher frequency of daily snacking (p = 0.013) was positively associated with local-based food pattern. For Chinese adolescents, age (p < 0.001), PA levels (p < 0.001) and maternal education level (p = 0.035) showed positive associations with the healthy-based pattern, whereas high EatOut (p = 0.001) and fast food intakes (p = 0.001) were negatively associated. Higher weekly consumption of EatOut (p = 0.007), fast food (p = 0.023) and carbonated beverages (p = 0.023), and daily snacking practice (p = 0.004) were positively associated with higher Western-based food pattern, whereas age (p = 0.004) was inversely associated.

    CONCLUSION: This study showed that there were significant differences in dietary patterns and its association factors between Malay and Chinese adolescents. More importantly, these findings suggest that unhealthy dietary and lifestyle practices could increase the risk of adherence to unhealthy Western-based food pattern that is high in fat, sugar and salt contents, and, consequently, increase the risk of developing obesity and metabolic-related disorders during these critical years of growth.

    The present study compared the rates of negative body image and risk for disordered eating in young women who identify as part of goth subculture and a matched sample. Participants were 80 women who identified as part of goth subculture and a matched sample of 82 women from London, United Kingdom. Participants completed measures of self-ideal body size discrepancy, body appreciation, appearance investment, and eating disorder symptomatology. Between-group comparisons indicated that goth women reported significantly higher drive for thinness (d=0.51), body dissatisfaction (d=0.62), and dysfunctional appearance investment (d=0.52), as well as lower body appreciation (d=0.55), than the matched sample. Heightened expectations about appearance and self-presentation, alongside appearance competitiveness, may result in more negative body image and disordered eating in young women who identify with goth subculture, but further research is necessary on this under-studied youth subculture.

    This study aimed to examine the role of psychological distress in the relationships between sociocultural influences (social pressure to be thin and weight teasing) and disordered eating. Data were collected from 584 university students (59.4% females and 40.6% males), aged 18-24 years old (M=20.6, SD=1.4), selected from four universities in the Klang Valley, Malaysia. Participants completed four standardized questionnaires which measured social pressure to be thin, weight-related teasing, psychological distress and disordered eating. A good fit structural equation modeling (SEM) model was developed for both sexes. For males, the SEM model revealed that sociocultural influences showed an indirect effect on disordered eating through psychological distress. For females, the model showed an indirect effect of sociocultural influences on disordered eating through psychological distress, as well as a direct effect of sociocultural influences on disordered eating. In conclusion, psychological distress mediated the relationships between sociocultural influences and disordered eating in both males and females. Our results suggest that disordered eating intervention programs on reducing psychological distress in university students may be beneficial.

    The construct of intuitive eating is most often measured using the 23-item Intuitive Eating Scale-2 (IES-2). Here, we examined the psychometrics of a Romanian translation of the IES-2. Eight-hundred-and-thirty Romanian adults completed the IES-2 along with measures of positive body image, symptoms of disordered eating, and psychological well-being. Exploratory factor analyses (EFAs) with a split-half subsample (n = 420) indicated that IES-2 scores reduced to three factors in women and four in men, both of which diverged from the parent model. Confirmatory factor analysis with a second split-half sample (n = 410) indicated that the parent model had poor fit indices, whereas fit of the EFA-derived models were acceptable but not uniformly ideal. Scores on the 3-factor model - which had comparatively better fit of the models tested - had adequate internal consistency and evidenced scalar invariance across gender. However, evidence of test-retest reliability after four weeks (n = 205) was poor and evidence of construct validity, assessed through correlations with additional measures included in the survey, was weak at best. Based on these results, we question the degree to which the construct of intuitive eating can be applied to nations undergoing nutrition transitions.

    BACKGROUND: Recent research suggests that a negative relationship exists between adiposity and cognitive function in children. However, limited information is known on how they are related. This study aimed to examine the mediators of the relationship between overweight/obesity and cognitive function among school children in Kuala Lumpur, Malaysia.

    METHODS: This is a cross-sectional comparison study whereby 225 overweight/obese children matched for age, sex, and ethnicity with 225 normal weight children participated in this study. Body image dissatisfaction, disordered eating, and depressive symptoms were assessed through a self-administered questionnaire. Blood pressure was measured, whereas blood was drawn to determine insulin, high-sensitivity C-reactive protein (hs-CRP), glucose, and lipid profiles. Homeostasis model assessment-estimated insulin resistance (HOMA-IR) was calculated using glucose and insulin levels. Wechsler's Intelligence Scale for Children-Fourth Edition (WISC-IV) was used to assess cognitive function in children. Ordinary least square regression analysis was conducted to determine the direct and indirect relationships between weight status and cognitive function.

    RESULTS: A negative relationship was found between overweight/obesity with cognitive function. Overweight/obese children were on average 4.075 units lower in cognitive function scores compared to normal weight children. Such difference was found through mediators, such as body image dissatisfaction, disordered eating, depression, systolic blood pressure, triglycerides, HOMA-IR, and hs-CRP, contributing 22.2% of the variances in cognitive function in children.

    CONCLUSION: Results highlight the important mediators of the relationship between overweight/obesity and cognitive function. Consequently, future interventions should target to improve psychological well-being and reduce cardiovascular disease risk for the prevention of poorer cognitive performance in overweight/obese children.

    It is well documented that short sleep duration is associated with excess body weight and poor food intake in children. It has been suggested that sleep timing behaviour may also be an important predictor of weight and other related behaviours, independent of sleep duration; however, there is a lack of research investigating these relationships. The present study investigated sleep timing in association with diet and physical activity levels in 439 children aged 9-11 years old from New Zealand. Sleep and physical activity data were collected using accelerometry, and food choice using a short food-frequency questionnaire. Participants were classified into one of four sleep timing behaviour categories using the median split for sleep-onset and -offset times. Differences between sleep timing groups for weekly consumption frequency of selected food groups, dietary pattern scores and minutes of moderate-to-vigorous physical activity were examined. Children in the late sleep/late wake category had a lower 'Fruit & Vegetables' pattern score [mean difference (95% CI): -0.3 (-0.5, -0.1)], a lower consumption frequency of fruit and vegetables [mean weekly difference (95% CI): -2.9 (-4.9, -0.9)] and a higher consumption frequency of sweetened beverages [mean weekly difference (95% CI): 1.8 (0.2, 3.3)] compared with those in the early sleep/early wake category. Additionally, children in the late sleep/late wake category accumulated fewer minutes of moderate-to-vigorous physical activity per day compared with those in the early sleep/early wake category [mean difference (95% CI): -9.4 (-15.3, -3.5)]. These findings indicate that sleep timing, even after controlling for sleep duration, was associated with both food consumption and physical activity.

    BACKGROUND & AIMS: Several questionnaires to screen for eating disorders have been validated in Malaysia. However, these tools are lengthy, and require specialist interpretation. The sick, control, one stone, fat, food (SCOFF) is easy to administer by non-specialists, but has not been validated in Malaysia. Therefore, the aim of our study was to validate the SCOFF on a non-clinical sample of tertiary students to determine if it could identify individuals with an eating disorder.
    METHODS: We recruited second year tertiary students from five faculties in a university in Malaysia, from June-November 2014, who could understand English. The SCOFF and the EAT-26 were administered at baseline. Two weeks later, the SCOFF was re-administered to assess for reliability.
    RESULTS: A total of 292 students were approached, and all agreed to participate (response rate = 100%). There was moderate correlation between the total SCOFF score with the EAT-26's dieting domain (spearman's rho = 0.504, p < 0.001), bulimia and food preoccupation domain (spearman's rho = 0.438, p < 0.001), and total score (spearman's rho = 0.483, p < 0.001). The internal consistency of the SCOFF was low (Cronbach alpha = 0.470). At retest, kappa scores ranged from 0.211 to 0.591. The sensitivity of the SCOFF was 77.4%, and its specificity was 60.5%. The positive predictive value was 18.9%, and its negative predictive value was 95.8%.
    CONCLUSIONS: The SCOFF was found to have adequate convergent validity and stable reliability. However, its internal consistency was low. The SCOFF can still be used in clinical practice. However, its positive results should be interpreted with caution due to its low positive predictive value.

    To limit the spread of the novel coronavirus (COVID-19), many countries have introduced mandated lockdown or social distancing measures. Although these measures may be successful against COVID-19 transmission, the pandemic and attendant restrictions are a source of chronic and severe stress and anxiety which may contribute to the emergence or worsening of symptoms of eating disorders and the development of negative body image. Therefore, in this study, we aimed to: (1) classify different conditions associated with COVID-19-related stress, COVID-19-related anxiety, and weight status; and (2) analyze and compare the severity of dimensions typically related to eating disorders symptomatology and body image in individuals with different COVID-19-related stress, COVID-19-related anxiety, and weight status. Polish women (N = 671, Mage = 32.50 ± 11.38) completed measures of COVID-19-related stress and anxiety along with body dissatisfaction, drive for thinness, and bulimia symptomatology subscales of the Eating Disorders Inventory, and the appearance evaluation, overweight preoccupation, and body areas satisfaction subscales of the Multidimensional Body-Self Relations Questionnaire. The following four clusters were identified through cluster analysis: (a) Cluster 1 (N = 269), healthy body weight and low COVID-related stress (M = 3.06) and anxiety (M = 2.96); (b) Cluster 2 (N = 154), healthy body weight and high COVID-related stress (M = 5.43) and anxiety (M = 5.29); (c) Cluster 3 (N = 127), excess body weight and high COVID-related stress (M = 5.23) and anxiety (M = 5.35); (d) Cluster 4 (N = 121), excess body weight and low COVID-related stress (M = 2.69) and anxiety (M = 2.83). Our results showed that Clusters 3 and 4 had significantly greater body dissatisfaction and lower appearance evaluation and body areas satisfaction than Clusters 1 and 2. Cluster 3 also had a significantly higher level of drive for thinness, bulimia, and overweight preoccupation than Clusters 1 and 2. These preliminary findings may mean that the COVID-19 pandemic and attendant anxiety and stress caused by the pandemic are exacerbating symptoms of eating disorders and negative body image, with women with excess weight particularly at risk.

    The genetic property of subclinical eating behaviour (SEB) and the link between SEB and polycystic ovary syndrome (PCOS) has been studied before but the role of leptin within this connection has never been investigated. The objective of this study was 1). to study the genetic property of SEB. 2). To find a link between leptin, SEB and PCOS. One hundred and fifty four (77 pairs) female-female Iranian twins including 96 MZ individuals (48 pairs) and 58 DZ individuals (29 pairs) participated in the study. Clinical, biochemical and ultrasound tools were used to diagnose polycystic ovary syndrome. BITE questionnaire was filled out for subjects. Eight percent of subjects were diagnosed for subclinical eating disorder. No significant difference was found between intraclass correlation of MZ and DZ (z = 0.57, P = 0.569). Serum leptin level correlated significantly with bulimia score (P < 0.007). The mean (+/-SD) value for bulimia score was found to be higher among PCOS(positive) subjects (3.27 +/- 5.51) in comparison with PCOS(negative) subjects (2.06 +/- 4.48) (P < 0.001). The genetic property of subclinical eating disorder was not confirmed as shared environment might have played a major role in likeliness of DZ twins as well as MZ. Leptin is linked with both subclinical eating disorder and PCOS.

    The purpose of this case study is to report the use of oral Bovril (a food supplement which contains arginine) as an alternative test for growth hormone stimulation test. We performed oral Bovril test in 3 patients -- one with suspected growth hormone deficiency in whom insulin tolerance test could not be performed (subject A), one sex-matched control (subject B), and one with confirmed growth hormone deficiency (subject C). 14g/m(2) of oral Bovril was mixed with 150ml of warm water and was given to all three subjects. Blood for growth hormone was taken at baseline, and every 30 minutes till 150 minutes after ingestion of oral Bovril. The ingestion of oral Bovril showed a positive response in subjects A and B, with highest growth hormone levels of 28.4mIU/L and 42.0mIU/L respectively at 150 minutes. Subject C had suppressed growth hormone throughout the test. Oral Bovril is readily available and is a safe alternative for standard growth hormone stimulation test.

    Accurately measuring the phenotype at the individual level is critical to the success of selective breeding programs. Feed efficiency is a key sustainability trait and is typically approached through feed conversion ratio (FCR). This requires measurements of body weight gain (BWG) and feed intake (FI), the latter being technically challenging in fish. We assessed two of the principal methods for measuring feed intake in fish over consecutive days: (1) group rearing 10 fish per group and video recording the meals and (2) rearing fish individually on a restricted ration. Juvenile Nile tilapia (Oreochromis niloticus) from the Genetically Improved Farmed Tilapia (GIFT) strain and the Cirad strain were entered into the study (128 GIFT and 109 Cirad). The GIFT strain were reared over three consecutive periods of 7 days each under different feeding, recording, and rearing scenarios (i) in groups fed an optimal ration (g100) or (ii) fed a 50% restricted ration (g50) both with video records of all meals and (iii) reared in isolation and fed a 50% restrictive ration. The Cirad strain were tested similarly but only for scenarios (i) and (iii). All fish were fed twice daily with a calculated ration. Correlations showed the same trends for the GIFT and the Cirad strains. For the GIFT strain, correlations were positive and significant for BWG and FI measured in scenarios (i) and (ii), 0.49 and 0.63, respectively, and FI measured in scenarios (i) and (iii) (0.50) but not for BWG measured in scenarios (i) and (iii) (0.29, NS). The phenotypic correlation estimated for FCR between scenarios (i) and (ii) with fish fed an optimal or a 50% restricted ration was low and not significant (0.22). Feed Conversion Ratio for GIFT fish reared in groups or in isolation and fed with a restricted ration [scenarios (ii) and (iii)] were not significantly correlated either. Social interactions between fish, potentially impacting their efficiency, may explain the results. Therefore, selective breeding programs seeking to improve feed efficiency will need to carefully plan the feeding rate and the rearing system used to estimate FCR in order to optimize selection for the targeted production system.
