Healthy Change Intervention: A Cluster RCT in Preschooler Mothers in Mexico and the United States.

Objective: To assess effects of Healthy Change intervention on maternal perception of her child's body weight (MPCW), maternal feeding style, and obesogenic home environment.

Methods: A randomized control trial was conducted, consisting of two arms: the intervention group received the Healthy Change program, and the control group received the Hygiene and Accident Prevention program. A total of 356 mother-preschool child dyads participated, 182 in the intervention group and 174 in the control group, residing in Mexico and the United States.

Evaluation of the Effect of Influenza Vaccine on the Development of Symptoms in SARS-CoV-2 Infection and Outcome in Patients Hospitalized due to COVID-19.

Background: COVID-19 is an infectious disease caused by SARS-CoV-2. It is unclear whether influenza vaccination reduces the severity of disease symptoms. Previous studies have suggested a beneficial effect of influenza vaccination on the severity of COVID-19.

Less underestimaton of excess weight by the categorical than the visual method. Its determinants and feeding practices in Mexican mothers of children aged 2 to 12 years.

Introduction: perceived body weight refers to the subjectively assessed weight, which may not correspond to the objectively measured weight. Statistics show that 14 % to 83 % of parents misperceive their children's weight status, with a propensity for underestimation. Objective: we compared the accuracy of the visual versus the categorical method.

Impacts of an early childhood obesity prevention program in Mexico.

The Healthy Change Program aimed to improve the accuracy of maternal perceptions of children's weight (MPCW), maternal feeding style (MFS) and feeding practices. Using a randomized control trial design, the intervention group received 4-weekly group sessions focusing on MPCW, MFS and healthy behaviors. The control group received the same dose of attention-control sessions on food hygiene.

Evaluation of the Potential Risk of Mortality from SARS-CoV-2 Infection in Hospitalized Patients According to the Charlson Comorbidity Index.

The pandemic of COVID-19 has represented a major threat to global public health in the last century and therefore to identify predictors of mortality among COVID-19 hospitalized patients is widely justified. The aim of this study was to evaluate the possible usefulness of Charlson Comorbidity Index (CCI) as mortality predictor in patients hospitalized because COVID-19. This study was carried out in Zacatecas, Mexico, and it included 705 hospitalized patients with suspected of SARS-CoV-2 infection.

Population-Based COVID-19 Screening in Mexico: Assessment of Symptoms and Their Weighting in Predicting SARS-CoV-2 Infection.

: Sentinel surveillance in the early stage of the COVID-19 pandemic in Mexico represented a significant cost reduction and was useful in estimating the population infected with SARS-CoV-2. However, it also implied that many patients were not screened and therefore had no accurate diagnosis. In this study, we carried out a population-based SARS-CoV-2 screening in Mexico to evaluate the COVID-19-related symptoms and their weighting in predicting SARS-CoV-2 infection.

The Influence of Obesity on Puberty and Insulin Resistance in Mexican Children.

Obesity is considered the main risk factor associated with the development of insulin resistance (IR). The aim of this study was to evaluate the influence of obesity on puberty onset and IR in Mexican children. A total of 378 children (189 boys and 189 girls) aged 8-14 years participated in the study.

Study protocol: intervention in maternal perception of preschoolers' weight among Mexican and Mexican-American mothers.

Background: Childhood obesity is a public health issue negatively affecting children's physical and psychosocial health. Mothers are children's primary caregivers, thus key players in childhood obesity prevention. Studies have indicated that mothers underestimate their children's weight.

Maternal distress and the development of hypertensive disorders of pregnancy.

Despite the implementation of programmes to improve maternal health, maternal and foetal mortality rates still remain high. The presence of maternal distress and its association with the development of pregnancy hypertensive disorders is not well established. The aim of this study was to evaluate the association between maternal distress and the development of hypertensive disorders in pregnancy in a prospective cohort of 321 Mexican women.

[Quality of professional life and musculoskeletal disorders in nurses].

Objective: To characterize the conditions of quality of working life, the presence of muscle- skeletal disorders and the association between these variables in nursing staff of a public hospital in Zacatecas, Mexico.

Method: A cross-sectional study with descriptive-correlational scope was designed. A stratified random sampling per shift was used in 107 cases.

[Maternal actions and problems in managing the child's weight and their association with the maternal perception of the weight and age of her child].

Introduction: To properly perceive the child's weight may influence the mother to start up changes to prevent and manage overweight problems.

Objectives: 1) To assess whether the actions and problems to manage the child's weight are different according to the nutritional status and the perception on the child's weight; and 2) to assess whether the actions and problems are different according to the child's age.

Methods: 2840 mothers and sons/daughters (age 2-17 years) from North-eastern Mexico participated.
