Chronic diseases in childhood can affect the physical and mental health of patients and their families. The objective of this study was to identify the sociodemographic and psychosocial factors that predict resilience in family caregivers of children with cancer and to define whether there are differences in the levels of resilience derived from these sociodemographic variables. Three hundred and thirty family caregivers of children with cancer, with an average age of 32.6 years were interviewed. The caregivers responded to a battery of tests that included a questionnaire of sociodemographic variables, the Measuring Scale of Resilience, the Beck Depression Inventory, the Inventory of Quality of Life, the Beck Anxiety Inventory, an interview of caregiver burden and the World Health Organization Well-Being Index. The main findings indicate that family caregivers of children with cancer reported high levels of resilience, which were associated positively with quality of life, psychological well-being and years of study and associated negatively with depression, anxiety and caregiver burden. The variables that predicted resilience in families of children with cancer were quality of life, psychological well-being, depression and number of children. Family caregivers who were married and Catholic showed higher resilience scores. We conclude that being a caregiver in a family with children with cancer is associated with symptoms of anxiety and with depressive episodes. These issues can be overcome through family strength, well-being, quality of life and positive adaptation processes and mobilization of family resources.

The resilience to face disease is a process of positive adaptation despite the loss of health. It involves developing vitality and skills to overcome the negative effects of adversity, risks, and vulnerability caused by disease. In Mexico, the Mexican Resilience Measurement Scale (RESI-M) has been validated with a general population and has a five-factor structure. However, this scale does not allow evaluation of resilience in specific subpopulations, such as caregivers. This study investigated the psychometric properties of RESI-M in 446 family caregivers of children with chronic diseases. A confirmatory factor analysis (CFA) was performed, internal consistency values were calculated using Cronbach’s alpha coefficient, and mean comparisons were determined using t-tests. The expected five-factor model showed an adequate fit with the data based on a maximum likelihood test. The internal consistency for each factor ranged from .76 to .93, and the global internal consistency was .95. No average difference in RESI-M and its factors was found between women and men. The RESI-M showed internal consistency and its model of five correlated factors was valid among family caregivers of children with chronic diseases.

This study analyzes the potential economic benefits of identifying and treating patients with so-called prediabetes and prehypertension through the Mexican prevention program known by its Spanish acronym PREVENIMSS. The results show that for each US dollar invested in prevention, $84–$323 would be saved over a twenty-year period. For this and other reasons, providing preventive care for prediabetes and prehypertension patients is better than the current routine care model, in which care is provided in most cases when the disease has progressed substantially. Yet data show that screening and preventive care services are still not being used widely enough in Mexico, are provided too late, or are not sufficiently targeted to the most at-risk individuals. Investing in preventive care for patients with prediabetes and prehypertension is cost saving.

To examine the burden of out-of-pocket household expenditures and time spent on care by families responsible for children with Down Syndrome (DS). A cross-sectional analysis was performed after surveying families of children with DS. The children all received medical care at the Hospital Infantil de México Federico Gomez (HIMFG), a National Institute of Health. Data were collected on out-of-pocket household expenditures for the medical care of these children. The percentage of such expenditure was calculated in relation to available household expenditure (after subtracting the cost of food/housing), and the percentage of households with catastrophic expenditure. Finally, the time spent on the care of the child was assessed. The socioeconomic analysis showed that 67% of the households with children with DS who received medical care in the HIMFG were within the lower four deciles (I-IV) of expenses, indicating a limited ability to pay for medical services. Yearly out-of-pocket expenditures for a child with DS represented 27% of the available household expenditure, which is equivalent to $464 for the United States dollars (USD). On average, 33% of families with DS children had catastrophic expenses, and 46% of the families had to borrow money to pay for medical expenses. The percentage of catastrophic expenditure was greater for a household with children aged five or older compared with households with younger children. The regression analysis revealed that the age of the child is the most significant factor determining the time spent on care. Some Mexican families of children with DS incur substantial out-of-pocket expenditures, which constitute an economic burden for families of children who received medical care at the HIMFG.

Objective. To estimate direct medical costs (DMC) associated with treatment of Respiratory Distress Syndrome (RDS) in newborns (NB) in two specialized public hospitals in Mexico. Materials and methods. The perspective used was health care payer. We estimated DMC associated with RDS management. The pattern of resource use was established by reviewing clinical records. Microcosting and bootstrap techniques were used to obtain the DMC. Estimated costs were reported in 2011 US dollars. Results. Average DMC per RDS event was 14226 USD. The most significant items that account for this cost were hospitalization (38%), laboratory and diagnostic exams (18%), incubator time (10%), surfactant therapy (7%), and mechanical ventilation (7%). Conclusion. Average DMC in NB with RDS fluctuated in relation to gestational age weight at birth and clinical complications presented by patients during their hospitalization.
