[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.

[Impact of electronic devices used at an early age on language]

Background

The acquisition of language in infants is largely the result of the process of brain maturation, as well as environmental stimulation. Currently, society is in an era of technology and use of electronic devices from an early age.

Objective

The aim of this study was to demonstrate if the amount of time of use of electronic devices in children under 5 years of age affects language development.

Methods

An observational, comparative, survey-type study was carried out in 269 infants of both sexes, with an age range of 6 to <60 months. The language development section of the Child Development Scale (EDI) was used. A logistic regression was performed to determine the strength of association between the factors to be studied.

Results

269 participants were included, of which 224 (83.2%) presented their level of neurological maturation, 44 infants (16.4%) presented laged development and one (0.4%) was classified as having developmental delay. It was found that the number of daily hours that an electronic device is used behaved as a risk factor by increasing the risk of delayed language development by 1.37 times for each hour of exposure (OR: 1.37, CI95%: 1.15-1.62).

Conclusions

It was shown that a greater number of hours of use of electronic devices is a risk factor for delayed language development in children under 5 years of age. Therefore, it is vital to limit its use in this population.
