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

Study on the stability of molecular chirality and the configuration protection of dihydromyricetin in vine tea

This study aims to investigate the impact of four key factors, namely, temperature, water source, metal ion, and pH, on the stability of molecular chirality of dihydromyricetin (DMY) and proposed effective strategies for configuration protection. The findings reveal that temperatures exceeding 80°C could accelerate the racemization process of DMY, with a significant increase in racemization observed at 100°C. In addition, DMY exhibited heightened stability in ultrapure water as compared to various water sources, including pure water-1, pure water-2, mineral water, and running water. Notably, the presence of Fe2+ displayed an inhibitory effect on the racemization of DMY, whereas Mg2+, Ca2+, and Mn2+ showed a substantial promotional effect. Additionally, acidic conditions (pH < 5.0) were found to be protective for maintaining the stability of DMY, whereas alkaline conditions (pH > 9.0) were observed to be detrimental. Meanwhile, we first identified the presence of another pair of DMY isomers in this work.

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.

Comparison of eating behaviour by relative weight change status of young adults throughout the COVID-19 pandemic

Background and purpose

The enforcement of nationwide lockdowns has worsened the obesity epidemic in Malaysia. Therefore, this study aims to compare eating behaviour by relative weight change status among young adults in Malaysia throughout the COVID-19 pandemic.

Design/methodology/approach

Socio-demographics, body height, pre-pandemic body weight, and post-lockdown body weight were self-reported by the young adults. The eating behaviour was assessed using the validated Three-Factor Eating Questionnaire-Revised 18-item (TFEQ-R18). The mean difference in eating behaviour subscales was analysed using MANCOVA with a Bonferroni-adjusted post-hoc test.

Findings

One-third of the young adults put on body weight due to the lockdowns, with an average relative weight gain of 12.44 ± 9.67%. Conversely, about one-fifth of the young adults reported having lighter body weight in the post-lockdown pandemic phase, with an average relative weight loss of 10.10 ± 4.66%. Young adults in the weight loss category had a significantly higher standardised raw score in cognitive restraints than those in the sustained weight and weight gain categories. In addition, young adults in the weight gain category had statistically higher standardised raw scores in uncontrolled eating and emotional eating compared to those in the sustained weight category. Weight trajectory during the COVID-19 pandemic is linked to disordered eating behaviour among young adults in Malaysia.

Originality/value

The findings presented in this study can be potentially valuable in formulating weight management strategies in the post-COVID-19 era.

The correlations between food security, diet quality and weight change among working women of reproductive age during the endemic phase of COVID-19

Aim

This cross-sectional study aims to investigate the correlations between food security, diet quality and weight change among working women during the endemic phase of COVID-19 in the Klang Valley of Malaysia.

Methods

Working women aged 18-49 years were required to self-report their socio-demographics and pre-pandemic body weight (body weight during February 2020). Body height and current body weight were measured using a SECA stadiometer and TANITA weighing scale. Food security was assessed using the Food Insecurity Experience Scale (FIES); the diet quality was determined with the Diet Quality Questionnaire (DQQ) for Malaysia.

Results

The prevalence of moderate-to-severe food insecurity was 19.9%. It is noted that 64.3% of working women gained weight throughout the pandemic, with an average weight gain of 4.36 ± 3.19 kg. Concerning diet quality, the majority (82.5%) achieved the Minimum Dietary Diversity for Women (MDD-W). Findings from linear regression revealed that food security was not significantly correlated with weight change. However, working women who failed to achieve the MDD-W gained, on average, 1.853 kg more than those who did (p = 0.040). On the other hand, no significant correlation was observed between food security status and diet quality in weight change of working women.

Conclusion

The current study shall provide an impetus to develop intervention strategies for promoting healthy eating among working women.

The Prevalence and Determinants of Child Hunger and Its Associations with Early Childhood Nutritional Status among Urban Poverty Households during COVID-19 Pandemic in Petaling District, Malaysia: An Exploratory Cross-Sectional Survey

Child hunger was prevalent during the COVID-19 pandemic, but the extent, determinants, and impact on pre-school children aged 6 months to 7 years old from Malaysian urban poor households are still unknown. This exploratory cross-sectional study was performed between July 2020 and January 2021 at the Lembah Subang People Housing Project, Petaling. The households' food security status was assessed using the previously validated Radimer/Cornell questionnaire, and the children's anthropometric measurements were taken. Food diversity score was assessed using the World Health Organization Infant and Young Children Feeding (under-2 children) or Food and Agriculture Organization Women's Dietary Diversity (2-year-old-and-above children) systems. Overall, 106 households were recruited. The prevalence of child hunger is 58.4% (95% CI: 50.0, 67.4). Significant differences were found in breastfeeding and sugar-sweetened beverage consumption between under-2 and ≥2-year-old children. There were no significant differences between child hunger and other food-insecure groups in weight-for-age, height-for-age, and weight-for-height z-scores. Only a higher dietary diversity score was significantly protective against child hunger after adjusting for maternal age, paternal employment status, and the number of household children (OR_adjusted: 0.637 (95% CI: 0.443, 0.916), p = 0.015)). Proactive strategies are warranted to reduce child hunger during the COVID-19 pandemic by improving childhood dietary diversity.

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.
