Factors Associated With Dietary Quality During Initial and Later Stages of the COVID-19 Pandemic in Mexico

An internet-based self-help intervention for the reduction of consumption of ultra-processed products and increase of physical activity in Mexican university population: study protocol for a randomized controlled trial

Introduction

The consumption of ultra-processed products has been associated with the etiology of various diseases, mainly metabolic diseases. On the other hand, physical activity acts as a protective factor that helps prevent the appearance of this type of disease. In addition to the physical effects, both the consumption of ultra-processed products (UPPs) and sedentary behaviors have been associated with a significant impact on people's mental health. These problems occur significantly in university students. Online internet interventions are an alternative that has the advantage of reaching a broader sample size and adapting to various problems.

Methods

A randomized controlled clinical superiority trial with two independent groups will be developed with 176 participants. Participants in both groups will be evaluated in 5 steps: (1) pretest, (2) middle of the intervention, (3) post-test, (4) follow-up at 3 months, and (5) follow-up at 6 months. In the experimental group ("UNISALUD"), participants will receive an intervention composed of 11 sessions with interactive elements such as videos, audio, and infographics created through the user experience (UX) principles and based on the health action process approach (HAPA). The participants in the control group will be on the waiting list and will receive treatment 27 days after fulfilling the inclusion criteria. Thus, participants will not receive the treatment immediately.

Discussion

The study is expected to establish the feasibility of a self-help internet-based intervention created based on the user experience methodology and the health action process model, leading to a significant decrease and increase in the consumption of UPPs, ultra-healthy products, and physical activity, respectively.

Conclusion

Internet-based interventions are scarce in Latin America. Due to their potential, this study will provide data about consumption of UPPs, physical activity, and mental health of the Mexican population, which will influence the reduction of health-related complications through prevention strategies or measures.Clinical Trial Registration:ClinicalTrials.gov, NCT05834842.

Diet quality in medical trainees: a cross-sectional assessment comparing medical students and primary care residents using the Rapid Eating Assessment for Participants-shortened version

BACKGROUND

The diet quality of the US population is significantly unhealthy, with critical long-term implications for the nation's health. A few studies have explored diet quality in the future primary care workforce. This cross-sectional study quantifies the diet quality of medical students and primary care residents at a Midwestern college of medicine in the United States.

METHODS

250 medical students and 148 primary care residents were surveyed electronically utilizing the Rapid Eating Assessment for Participants-Shortened Version (REAP-S). The survey consists of 13 questions that can be scored on a scale from 1 to 3, along with 3 questions that are not scored. The average REAP-S score for a US omnivorous diet is 32 (range 13 to 39) with higher scores indicating a higher quality diet. We obtained average REAP-S scores for all respondents and descriptive summary statistics for individual REAP-S items. Students' REAP-S total scores were compared to those of residents and the interaction between student/resident status and BMI category on REAP-S total scores were analyzed using analyses of variance. Differences between students and residents on BMI categories and other outcomes (individual REAP-S items, pandemic dietary and weight changes) were analyzed using Chi-Square Tests of Independence or Fisher's Exact Tests.

RESULTS

Medical students (n = 99; 39.6% response rate) had a significantly higher mean REAP-S score (30.5, SD = 3.9) than primary care residents (n = 72; 49% response rate) (mean = 28.6, SD = 3.9; p = 0.006). Total mean REAP-S scores were significantly higher for those with BMI < 25 (mean = 30.8, SD = 3.7) than for those with BMI > = 25 (mean = 28.3, SD = 4.0; p < 0.001). There was not a statistically significant interaction between role (student vs. resident) and BMI category on total REAP-S scores (p = 0.39). Most respondents (89.3%) indicated that they were willing to improve their diet.

CONCLUSION

Our data suggest that the diet quality of surveyed medical students and primary care residents, as quantified by the REAP-S, is suboptimal. Early detection and improvement of diet quality may be necessary for our medical profession trainees to avert potential long-term adverse cardiometabolic health outcomes, and to optimize the health of our future primary care workforce.

[Diet and body weight at the beginning of the COVID-19 pandemic in Mexico]

Background

Weight changes in adults have strong repercussions on people's health status. During the COVID-19 pandemic, these changes could be more evident due to the mandatory confinement, as well as eating habits and lifestyle. In this study, changes in diet and body weight in Mexican population at the beginning of COVID-19 lockdown period (weeks 4-7) were evaluated using an online survey.

Objective

To identify the characteristics of the diet and the perceived change in body weight at the beginning of the COVID-19 pandemic in Mexico.

Material and methods

Descriptive, cross-sectional study of 1281 people over 18 years of age, electronic survey in weeks 4-7 of confinement with sociodemographic data, food consumption and perception of body weight.

Results

The change in food consumption was 53.9%, finding differences according to gender in beverages (carbonated, juices, alcoholic), coffee/tea, fruits, legumes (p < 0.05). The perception of body weight increases by 3.4 (increased) and 2.1 (lowered) times more than the risk of change in diet.

Conclusions

The dietary differences refer to a tendency to the type of food consumed, mainly sugary drinks, with the perception of changes in positive body weight in women.

A longitudinal investigation of dietary diversity during the COVID-19 pandemic in Mandinka households in Kanifing, Brikama, and the West Kiang region in The Gambia

The Covid pandemic has exposed fissures of inequality through heightened food insecurity and nutritional deficiency for vulnerable social cohorts with limited coping mechanisms. Given the multi-dimensional pathways through which its effects have been felt, several researchers have highlighted the need to analyse the pandemic in specific contexts. Using random and fixed effect regression models, this study analyzed longitudinal survey data collected from 103 Mandinka households in rural and urban Gambia. The study employed convenience and snowball sampling and involved the monthly collection of detailed income, food consumption, expenditure, sourcing, migration, health, and coping mechanism data through mobile phone interviews which yielded 676 observations. Food insecurity was manifest in terms of quality, not quantity, and spread unevenly across food types and households. Dietary outcomes and sourcing strategies were associated with location, improved sanitation, household size, changes in monthly income, Covid policy stringency, and Covid cases but these associations varied by food group. Staples were the most frequently consumed food group, and dark green vegetables were the least. Rural communities were more likely to eat more healthy millets but much less likely to consume dairy products or roots and tubers. Access to own production was also important for Vitamin A-rich foods but higher incomes and markets were key for protein and heme-iron-rich foods. Tighter Covid policy stringency was negatively associated with dietary diversity and, along with fear of market hoarding, was positively associated with reliance on a range of consumption and production coping mechanisms. Resilience was higher in larger households and those with improved water and sanitation. The number of Covid cases was associated with higher consumption of protein-rich foods and greater reliance on own produced iron-rich foods. Very few households received Government aid and those that did already had access to other income sources. Our findings suggest that the nature of food insecurity may have evolved over time during the pandemic. They also reiterate not only the importance of access to markets and employment but also that the capacity to absorb affordability shocks and maintain food choices through switching between sources for specific nutritious food groups varied by household and location.

Assessment of Dietary and Lifestyle Responses After COVID-19 Vaccine Availability in Selected Arab Countries

Background

The COVID-19 pandemic has been consistently associated with unhealthy lifestyle behaviors and dietary practices. This study aimed to assess the dietary and lifestyle behaviors of adults after COVID-19 vaccine availability and their attitude toward the vaccine in selected Arab countries.

Methods

A cross-sectional survey-based study was conducted between October 2021 and December 2021 using Google Forms (n = 2259). A multi-component questionnaire was used to collect socio-demographic characteristics, attitudes toward the COVID-19 vaccine, and behavioral, dietary, and lifestyle responses after easing the restriction. Participants were given a score based on the sum of positive dietary and lifestyle changes. The generalized linear models were used to identify the association between positive dietary and lifestyle changes score and sociodemographic characteristics.

Results

Weight gain during the pandemic was reported by 39.5% of the participants, 36.1% reported ever getting infected with the COVID-19 virus, and 85% received at least one dose of the vaccine. The key adverse reactions of the COVID-19 vaccine were fatigue, headache, and joint pain, and the main reason for vaccination was protection against infection. Most participants were concerned about the vaccine side effects (45.8%) and inadequate testing (50.7%). After easing of restriction, 54.3% of the participants reduced the frequency of disinfecting objects, and 58.3% joined social events. Most dietary and lifestyle behaviors remained unchanged after vaccine availability but there was an increase in the time spent behind the screen for work (50.1%) and entertainment (42.9%). The results of the multivariate regression analyses revealed that older participants (p = 0.001), those with higher education (p = 0.010), and those working from home (p = 0.040) were more likely to have higher positive dietary and lifestyle changes scores.

Conclusion

Although most participants were concerned about vaccine safety, low vaccine hesitancy rates were observed among the study sample. The availability of the COVID-19 vaccines resulted in loosening some of the safety social measures among Arab adults but the negative impact of the pandemic on dietary and lifestyle behaviors remained unaltered.

Food Insecurity across the Life-Course and Cognitive Function among Older Mexican Adults

BACKGROUND

Food insecurity remains a global public health problem. Experiencing food insecurity is related to poorer cognitive function among older adults. However, few studies have examined how food insecurity, experienced over the life-course, relates to cognitive function among older adults in Mexico.

METHODS

Data came from the 2015 Mexican Health and Aging Study (n = 11,507 adults aged 50 and over). Early- and late-life food insecurity were ascertained by self-report. We evaluated how both measures of food insecurity related to the performance of multiple cognitive tasks (Verbal Learning, Verbal Recall, Visual Scanning, and Verbal Fluency), while controlling for key health and sociodemographic confounders using linear regression.

RESULTS

In descriptive analyses, respondents who experienced food insecurity in either early or late life performed significantly worse on all cognitive tasks when compared to the food secure. In models adjusted for health and sociodemographic confounders, early-life food insecurity predicted worse Verbal Learning performance and late-life food insecurity was associated with poorer Visual Scanning performance.

CONCLUSIONS

Food insecurity was related to poorer cognitive function in a nationally representative sample of older adults in Mexico. However, results suggested that the significance of effects depended on cognitive task and when in the life-course food insecurity was experienced.
