Despite the social distancing and mobility restriction measures implemented for susceptible people around the world, infections and deaths due to COVID-19 continued to increase, even more so in the first months of 2021 in Mexico. Thus, it is necessary to find risk groups that can benefit from more aggressive preventive measures in a high-density population. This is a case-control study of suspected COVID-19 patients from Nuevo León, Mexico. Cases were: (1) COVID-19-positive patients and COVID-19-positive patients who (2) developed pneumonia, (3) were intubated and (4) died. Controls were: (1) COVID-19-negative patients, (2) COVID-19-positive patients without pneumonia, (3) non-intubated COVID-19-positive patients and (4) surviving COVID-19-positive patients. ≥ 18 years of age, not pregnant, were included. The pre-existing conditions analysed as risk factors were age (years), sex (male), diabetes mellitus, hypertension, chronic obstructive pulmonary disease, asthma, immunosuppression, obesity, cardiovascular disease, chronic kidney disease and smoking. The Mann-Whitney U tests, Chi square and binary logistic regression were used. A total of 56,715 suspected patients were analysed in Nuevo León, México, with 62.6% being positive for COVID-19 and, of those infected, 14% developed pneumonia, 2.9% were intubated and 8.1% died. The mean age of those infected was 44.7 years, while of those complicated it was around 60 years. Older age, male sex, diabetes, hypertension, and obesity were risk factors for infection, complications, and death from COVID-19. This study highlights the importance of timely recognition of the population exposed to pre-existing conditions to prioritise preventive measures against the virus.

Objective:Mexico ranks first in childhood obesity worldwide. However, little is known about the factors influencing maternal feeding practices. The present study aimed to estimate the prevalence of feeding practices and explore associations between weight concern, weight perception, sociodemographic characteristics and those feeding practices.Design:Cross-sectional.Setting:North-eastern Mexico.Participants:Mothers aged ≥18 years who were in charge of feeding a singleton child aged 2–6 years with no endocrine disease or visible genetic malformations (n 507). Information on six maternal feeding practices, concern and perception of the child’s weight and demographics were collected by interview. The mother’s and child’s height and weight were measured. The feeding practices questionnaire was subject to content, construct and convergent validity analysis. Then, mean feeding scores were obtained and prevalence and 95 % CI were determined for scores ≥3; multivariate logistic regression was performed.Results:Not modelling (63·5 %; 95 % CI 59·2, 67·8 %) and pressuring to eat (55·6 %; 95 % CI 51·2, 60·0 %) were the most frequent feeding practices, followed by easy access to unhealthy foods (45·4 %; 95 % CI 40·9, 49·8 %) and child control (43·2 %; 95 % CI 38·8, 47·6 %). They prevailed despite concern about the child’s excess weight or a perception of the child as overweight/obese. Education was associated with the highest number of practices (educated mothers used more pressuring to eat, less regulation and less easy access; or monitoring was less absent).Conclusions:The frequency of certain feeding practices needs to be improved. Emphasis on the child’s weight concern, obesity perception and maternal education is essential for optimizing intervention planning.

The findings suggest that IR had no effect on breast cancer risk; however HbA1c increased the risk in Latinas of Mexican origin who had not been diagnosed previously with prediabetes or diabetes and had no direct family history of breast cancer. Prospective studies are required to establish the impact of IR over time.

ObjectiveThe aim of this study was to explore the relationship between body frame size (BFS) and body image, self‐esteem, and health‐related quality of life (HRQL) in Mexican schoolchildren.MethodsThis cross‐sectional study included children aged 6 to 11 years. Body image, self‐esteem, and HRQL were evaluated through interviews. Two frame‐size measures, biacromial and bitrochanteric diameters, were collected and summed for categorizing BFS as small, medium, or large. Height and weight were also measured. Spearman's correlations were determined and adjusted by sex, age, and body mass index (BMI). Multiple logistic regression analyses were performed with the psychological measure as the binary dependent variable, the categories of BFS as the independent variable, and sex, age, and BMI as control variables.ResultsThe correlation between BFS and body image was 0.15 (P < .01) and after BMI adjustment was 0.07 (P > .05). BFS did not correlate with self‐esteem nor HRQL (P > .05). Of the children, 79% were dissatisfied with their body image, 20% had a low self‐esteem, and 31.8% had a poorly perceived HRQL; there were no differences by BFS. The multivariate analysis showed that a large BFS was not associated with body image dissatisfaction (OR 1.2, 95% CI 0.6‐2.3), low self‐esteem (OR 1.3, 95% CI 0.7‐2.6), or poor HRQL (OR 1.3, 95% CI 0.8‐2.2).ConclusionsBFS was not correlated with body image, self‐esteem, or HRQL. A high self‐esteem and a good level of HRQL prevailed, but a high proportion of children were dissatisfied with their body image. School interventions should promote an appropriate body image and a healthy lifestyle.

Objective To determine the most frequently body frame size (BFS) measurement and to compare the cut‐off values used for classifying body size in children and adolescents. Methods This systematic review focused on primary studies and scientific reports published in Medline Ovid, EMBASE, Web of Science, or Scopus between January 1, 2007 and March 31, 2021. Eligible studies must have included at least one BFS parameter measured in healthy children or adolescents. A descriptive analysis and graphic comparison were performed when values of the body frame were available. Results A total of 26 studies involving 317 202 children and adolescents from all over the world were included. The report of Frame index predominated (46%). It was followed by the biacromial diameter single or combined with the bitrochanteric and biiliocristal diameter (27%), the wrist circumference (19%), and the grant index (12%). Fourteen studies reported percentile values of the BFS measurement, but only four presented cut‐off values. Conclusions There was no unified BFS measurement in children and adolescents neither reference cut‐off values for categorization. The Frame index was the most frequently used. It is difficult to compare BFS statistics due to the diversity of measurements. It is necessary to standardize the use of the methods for measuring BFS.

The prevalence of prediabetes in a Mexican population at risk for cardiovascular disease and/or T2DM was high. Prediabetes is definitely a public health problem. Future studies are needed to examine the effectiveness and efficiency of pragmatic strategies to reverse the status of prediabetes and, therefore, reduce the incidence of T2DM.
