Relationships between Food Insecurity, Self-Efficacy, and Changes in Body Mass Index among the Youth in Taiwan: Analysis from a Longitudinal Cohort Survey.

BACKGROUND: Food insecurity is a heightened concern among economically disadvantaged youth, and it may contribute to the atypical body mass index (BMI) patterns frequently observed in this group. Self-efficacy seems to intervene in the negative impacts of contextual restraints. This study investigated the relationship between food insecurity, self-efficacy, and BMI trajectory among economically disadvantaged Taiwanese youth. METHODS: We utilized three-wave longitudinal data from the Taiwan Database of Children and Youth in Poverty. The Food Insecurity Score (FIS) assessed food insecurity with a 4-item scale measuring reduced meal frequency, hunger, skipping meals, and economic constraints. Moreover, the General Self-Efficacy Scale (GSES) assessed self-efficacy, showcasing the ability to handle stress effectively and envision success scenarios, contributing to positive outcomes. By employing latent growth modeling, we were able to delineate the impacts of baseline food insecurity and self-efficacy on initial BMI and its subsequent growth trajectory. RESULTS: Elevated baseline FIS significantly predicted higher initial BMI (coefficient = 0.420, p = 0.042). Baseline GSES was negatively associated with initial BMI (coefficient = -0.093, p < 0.001) but positively predicted the BMI growth rate (coefficient = 0.023, p = 0.011). CONCLUSION: Enhancing self-efficacy may be an effective multidisciplinary intervention to address psychosocial and socioeconomic factors when tackling weight problems in vulnerable youth groups.

Food insecurity, eating behaviour, and relative weight change among young adults in the aftermath of the COVID-19 lockdown.

This study aims to investigate the association between food insecurity, eating behaviour and relative weight change among Malaysian young adults in the aftermath of the pandemic-led lockdown. Socio-demographics, body height, and body weight were self-reported by the young adults. Food security was assessed using the 8-item validated Food Insecurity Experience Scale (FIES), while the Three-Factor Eating Questionnaire-Revised 18-item (TFEQ-R18) was adopted to evaluate the eating behaviour of young adults. Of the 447, 45.9% maintained the same body weight as before the pandemic-led lockdown. While almost half of the young adults (47.2%) were food secure, about one-fourth (24.8%) suffered moderate-to-severe food insecurity. Meanwhile, the standardised raw scores for all the eating behaviour subscales were in the ascending order of cognitive restraint (49.37 ± 18.60) < uncontrolled eating (50.61 ± 20.37) < emotional eating (50.68 ± 24.50). The findings of the Sobel test indicated that the mediation effects of eating behaviour were not statistically significant (p > 0.05), suggesting that eating behaviour (cognitive restraint, uncontrolled eating and emotional eating) did not mediate the relationship between moderate-to-severe food insecurity and relative weight change. Health promotion interventions such as introducing food assistance programs, offering incentives for nutritious food purchases, and re-emphasising healthy eating are essential to rectify food insecurity and disordered eating among Malaysians.

Knowledge, attitudes, and practices towards COVID-19 among undergraduates during emergency remote learning.

Background: The coronavirus disease 2019 (COVID-19) pandemic paralyzes the education sector. To minimize the interruption of teaching and learning, most universities in Malaysia shifted to virtual mode during this unprecedented period of the pandemic. With an ever-increasing number of Malaysians fully vaccinated against COVID-19, the education system is expected to switch back to face-to-face mode this year. It is crucial to assess the knowledge, attitudes, and practices (KAP) of COVID-19 among emergency remote learning undergraduates before reverting to physical teaching and learning. Hence, a study was conducted with this aim in mind. Methods: A total of 299 Malaysian undergraduates were recruited through a snowball sampling approach. The online questionnaire encompassed three main segments: informed consent, sociodemographic information, and KAP questions on COVID-19. Results: The mean scores for knowledge, attitude, and practice were 4.05/6, 11.14/12, and 5.07/7, respectively. The results of the present study showed that year 1 respondents had significantly higher levels (p < 0.05) of KAP scores than year 4 respondents. In addition, the attitude score of science majors respondents was significantly greater (p < 0.05) than those of nonscience majors. The KAP scores showed no significant difference among groups with different sexes, ethnicities, and COVID-19 histories. Partial correlation analysis revealed that the overall knowledge score was positively correlated with attitude (r = 0.193, p = 0.001) and practice (r = 0.343, p < 0.001) scores whereas the total attitude score was positively correlated with the total practice score (r = 0.149, p = 0.010). Conclusion: Our current results suggest that COVID-19 workshops, seminars, or training programs for year 4 students could be conducted to enhance their KAP levels.

Prevalence and factors associated with sexual dysfunction among middle-aged women in a multi-ethnic country: A cross sectional study in Malaysia.

Introduction: This study aimed to determine the prevalence and factors associated with female sexual dysfunction in an outpatient clinic in Malaysia. Methods: The study was conducted among female patients aged 50 years and older who attended the outpatient clinic of a public hospital in Malaysia. A self-administered questionnaire was used that was based on the Malay version of the Female Sexual Function Index questionnaire. The predictors of female sexual dysfunction were identified using multivariate logistic regression analysis. Results: A total of 263 females were recruited in this study, with a mean age of 60.6 ± 6.7 years. The distribution of the respondents' ethnicities was mostly Malay (42.2%), followed by Chinese (41.8%) and Indian (16.0%). The prevalence of female sexual dysfunction among participants was 68.8%. The prevalence of the subscales of female sexual dysfunction was as follows: desire (85.2%), satisfaction (74.9%), arousal (71.1%), lubrication (66.9%), pain (61.2%), and orgasm (60.8%). According to multivariate logistic regression, patients of Indian ethnicity had an increased risk of female sexual dysfunction (0R=16.60, 95% CI=2.54-108.63), and a higher frequency of sexual intercourse was correlated with a lower risk of female sexual dysfunction (0R=0.13, 95% CI=0.08-0.24). Conclusion: Seven-tenths of the middle-aged female patients attending the outpatient clinic suffered from female sexual dysfunction. Indian ethnicity and having a lower frequency of sexual intercourse were predictors of female sexual dysfunction. Future intervention studies are needed to address this problem.

Changes in Dietary Intake Patterns and Weight Status during the COVID-19 Lockdown: A Cross-Sectional Study Focusing on Young Adults in Malaysia.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) isolation has altered individuals' food purchasing behaviour and dietary intake patterns. Therefore, this study aims to investigate the changes in dietary intake patterns and their impacts on the weight status of young adults in Malaysia during the COVID-19 lockdown. METHODS: This cross-sectional study involved 1045 young adults in Malaysia. The changes in dietary intake patterns were assessed using the Dietary Diversity Questionnaire with slight modifications, while anthropometric measurements including body height, body weight before the pandemic and current body weight were self-reported. RESULTS: Overall, nearly half of the respondents (48.8%) gained weight during the confinement, with an average increment of 4.06 ± 3.23 kg. Of 1045, 45.3% reported consuming more fruits and 60.2% had higher plain water intake during the pandemic. It is observed that 41.0% to 66.8% of the young adults changed their dietary intake patterns during the pandemic. Increased consumption in cereals and grains (ß = 0.084, p = 0.015, 95% CI = 0.017-0.160), as well as oils and fats (ß = 0.123, p = 0.001, 95% CI = 0.059-0.241), was positively associated with weight gain during the pandemic. On the contrary, an increased plain water intake was negatively associated with weight gain during the lockdown (ß = -0.100, p = 0.003, 95% CI = -0.171--0.034). Findings in the current study also suggested that cutting back cereals and grains (ß = 0.156, p < 0.001, 95% CI = 0.122-0.288), as well as oils and fats (ß = 0.091, p = 0.012, 95% CI = 0.022-0.183), contributed significantly to weight loss during the pandemic confinement. CONCLUSION: In conclusion, the enforcement of the Movement Control Order (MCO) drove up the prevalence of overweight/obesity among young adults in Malaysia. Increased consumption of cereals and grains and oils and fats contributed to weight gain in the pandemic lockdown. Nonetheless, a noticeable proportion of young adults in Malaysia shifted to a healthier food choice by increasing the consumption of fruits and vegetables.

Effects of Sonication and Thermal Pasteurization on the Nutritional, Antioxidant, and Microbial Properties of Noni Juice.

Sonication is recognized as a potential food processing method to improve the functional properties of fruit juice. This study evaluated the effects of different sonication durations (20, 40, and 60 min) and thermal pasteurization on the nutritional, antioxidant, and microbial properties of noni juice. Fresh noni juice served as the control. The main organic acids detected were malic (57.54−89.31 mg/100 mL) and ascorbic (17.15−31.55 mg/100 mL) acids. Compared with the fresh sample, the concentrations of these compounds were significantly improved (p < 0.05) in the 60 min sonicated sample but reduced (p < 0.05) in the pasteurized sample. Moreover, sonication for 60 min resulted in increments of scopoletin, rutin, and vanillic acid compared to the fresh sample. The antioxidant activity of the juice sample was improved in the sample sonicated for 60 min. Irrespective of juice processing method, the level of microbial counts in noni juice was within the satisfactory level over the 8 weeks of refrigerated (4 °C) storage. This study highlights the feasibility of using ultrasound processing to enhance the quality of noni juice on the industrial scale.

Food security during the COVID-19 home confinement: A cross-sectional study focusing on adults in Malaysia.

The surge in coronavirus disease 2019 (COVID-19) transmission cases has led to the decision to execute the Movement Control Order (MCO) by the Federal Government of MalaysiaEconomic activities, psychological wellbeing, and food security may be negatively affected by the implementation of MCO. Therefore, this study aims to assess the prevalence of food insecurity and its associated factors during the enforcement of MCO 1.0. A total of 162 respondents were enrolled in this study using convenience and snowball sampling approaches. Socio-demographic information was self-reported by the respondents. Food security and the presence of depressive symptoms during the MCO 1.0 were assessed with Food Insecurity Experience Scale (FIES) and Patient Health Questionnaire-2 (PHQ-2), respectively. Current findings demonstrated that the prevalence of food insecurity was 43.2%. Ethnicity, marital status, employment status, monthly earned income and being the head of a household were significantly associated (p< 0.05) with food insecurity during the MCO 1.0. A higher odds ratio for food insecurity were observed among Malaysian Indian (OR = 2.541, CI: 1.041-6.205), those with active employment during the MCO 1.0 (OR = 4.175, CI: 1.189-14.660) and those with a monthly income of less than RM4000 during the MCO 1.0 (OR = 5.396, CI: 1.362-21.838). In conclusion, policymakers are urged to pay more attention to these vulnerable populations when formulating economic stimulus plans and coping strategies for food insecurity in the post-COVID-19 era.

Eating Behaviors among Online Learning Undergraduates during the COVID-19 Pandemic.

The outbreak of Coronavirus Disease-2019 (COVID-19) has upended education systems. The pandemic switched traditional face-to-face classes to online classes. Poor eating behaviors in undergraduate students' lives may affect the well-being of their later stages of life. This study aimed to investigate the eating behaviors among online learning undergraduates during the COVID-19 pandemic. A total of 122 students were recruited. The results revealed more than half of the respondents (52.46%) skipped meals. Breakfast (46.72%) was the most skipped meal. The majority of the respondents (94.26%) snacked between meals. Biscuits (88.52%), bread (84.43%), and fruits (80.33%) were the most common snacked foods. Meal skipping was found to be associated with gender (χ2 = 6.83, p < 0.05). In the future, more health interventions program aimed to promote healthy eating behaviors among undergraduates are highly warranted.

Trajectories of Food Choice Motives and Weight Status of Malaysian Youths during the COVID-19 Pandemic.

Stay-at-home orders have abruptly altered food purchasing behaviour, dietary habits, and food choice motives. Therefore, this study aims to investigate the trajectory of food choice motives and their associations with the weight status of Malaysian youths in the time of COVID-19. Socio-demographic information and anthropometric measurements were self-reported by the respondents, while the food choice motives were assessed using a validated 38-item food choice questionnaire (FCQ). Of the 1013 Malaysian youths, 48.6% gained weight due to the confinement, with an average weight gain of 3.90 ± 2.92 kg. On the other hand, 47.0% to 73.0% of the youths changed their food choice motives in the time of COVID-19. Of the 10 motives, convenience (48.5%) had the largest percentage increase, followed by weight control (47.0%) and health (45.3%). Moreover, the mean scores of health (t = -3.324, p = 0.001), convenience (t = -5.869, p < 0.001), weight control (t = -7.532, p < 0.001), natural content (t = -5.957, p < 0.001), ethical concern (t = -4.419, p < 0.001) and price (t = -3.737, p < 0.001) were significantly higher during the pandemic compared to pre-pandemic. Findings from the multinomial regression model revealed that youths highly concerned for weight control were more likely to be in the weight loss category (Adjusted odds ratio (AOR) = 1.633, Confidence Interval (CI) = 1.230-2.168, p = 0.001). Conversely, those who gained weight due to the pandemic confinement highly valued natural content in foods (AOR = 0.653, CI = 0.481-0.886, p = 0.006) when making their food choices in this unprecedented pandemic. In conclusion, Malaysian youths made healthier food choices to mitigate the risk of COVID-19 infection.

Physical Activity, Sedentary Behavior, and Weight Status of University Students during the COVID-19 Lockdown: A Cross-National Comparative Study.

The temporary closure of learning institutions during the COVID-19 pandemic has dramatically reduced the physical activity of students across all ages. Therefore, this study aimed to investigate the prevalence of physical inactivity and the patterns of physical activity among university students in confinement. This cross-sectional study involved 147 Malaysian students and 107 Indonesian students. Body weight before the pandemic and during the pandemic was self-reported by the respondents, and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) was used to assess the physical activity and sedentary behavior of the respondents. The findings revealed that 79.6% of Malaysians and 77.6% of Indonesians were physically active during the confinement. There was no significant difference (p < 0.05) in the duration devoted to vigorous-intensity activity (MMalaysian = 0.00 MET minutes/week and MIndonesian = 480.00 MET minutes/week) and moderate-intensity activity (MMalaysian = 0.00 MET minutes/week and MIndonesian = 0.00 MET minutes/week) among the studied population. During the pandemic, Malaysian students (M = 1386.00 MET minutes/week) devoted a significantly higher duration to walking (M = 1386.00 MET minutes/week) and sedentary behavior (9.16 ± 4.47 h/day) than Indonesian students (M = 990.00 MET minutes/week and sedentary behavior = 7.85 ± 4.27 h/day). Overall, no significant difference was noted in the total physical activity of Malaysian and Indonesian students during the pandemic (MMalaysian = 2826.00 MET minutes/week and MIndonesian = 1782.00 MET minutes/week). Findings from Spearman's rank correlation test suggested that there was a weak inverse correlation between the duration engaged in vigorous-intensity activity and weight change among the Malaysian students (rs = -0.199, p = 0.016), after adjusting for gender and age. Overall, the closure of learning institutions and exercise facilities has further prevented individuals from complying with the WHO recommendation of moderate-to-vigorous physical activity during the period of home confinement.

Effect of virgin avocado oil on diet-induced hypercholesterolemia in rats via 1 H NMR-based metabolomics approach.

Hypercholesterolemia is a major risk factor for the initiation and development of nonalcoholic fatty liver disease and atherosclerosis. The present study evaluated the hypocholesterolemic effect of virgin avocado oil (VAO) using urinary metabolomic method. Male Sprague-Dawley rats were fed high-cholesterol diet for four weeks to induce hypercholesterolemia. After confirming the establishment of hypercholesterolemia model, the VAO (450 and 900 mg·kg-1 ·day-1 ) and simvastatin (10 mg·kg-1 ·day-1 ) were given orally while maintaining the high-cholesterol diet for another four weeks. Assessment of urinary metabolomics using NMR revealed that VAO treatment could partially recover the metabolism dysfunction induced by hypercholesterolemia mainly via lipid, energy, amino acid, and gut microbiota metabolism.
