Objective. To describe the Medical Insurance for a New Generation (SMNG) as key public policy aimed at improving health care services for children under the age of five years in Mexico. Materials and methods. This paper analyzes interrelated aspects of public policies to provide health care to Mexican children: a) the demographic and health status of children, with emphasis on the wide disparities between children of varying demographics; b) the relationship of the main functions of a health care system: financing, equity, access and quality, with the provision of health care for children; c) the architecture of the Medical Insurance for a New Generation. Conclusion. SMNG is a program that can be instrumental in lowering infant mortality and alleviating the burden of families to care for sick children by improving access, quality of care and equity.


The health status of children under the age of five reflects the overall social conditions of the families, and the effectiveness of a country’s health and social programs.1 Mexico is working to keep up with the 4th Millenium Development Goal of reducing child mortality by two thirds in the year 2015. The country has experienced significant progress in reducing children’s malnutrition, morbidity and mortality. The results are not entirely satisfactory, and the government has recognized the need to implement policies to better ensure children’s health care.2

This paper aims to support the assumption that the Medical Insurance for a New Generation (Seguro Médico para una Nueva Generación, SMNG) is a viable health policy tool to tackle the inequities and reduce morbidity and mortality in Mexican children. It addresses the interrelated aspects that shape current health care public policies to provide health care to Mexican children. First, we analyze the health status and health needs of Mexican children. The focus is on the wide disparities that exist among them and the consequences of poor health in the short- and long-terms. The analysis includes nutritional status issues, such as malnutrition, overweight/obesity and anemia; it also involves the examination of infectious diseases that under-fives experience. Second, we address how the main functions of a health care system work together: financing, equity, access and quality to provide health care for children. Third, we describe the architecture of the Medical Insurance for a New Generation to support the assumption that mobilizing additional financial resources for health care services and providing financial protection improves the supply side, ad becomes a practical health policy tool to tackle the inequities that exist among Mexican children.

The health status of children in Mexico

Demographic conditions

Mexico is a mosaic of demographic and epidemiological conditions that feature substantial disparities in health, education, housing and employment opportunities. These disparities have a negative effect on the health status of Mexican children. To bridge the gap and reduce inequities, the Mexican government has launched a significant number of social and health programs. According to the 2010 Census of Population and Household, there were 10 528 322 children between the ages of 0 and 4 years in 2005, accounting for 9.3% of the 112 336 538 inhabitants of Mexico population.3 The life expectancy in Mexico is 76.6 years (men 74.2, women 79.1),2 to 3 years below the average of the Organization for Economic Cooperation and Development (OECD) member countries. The differences in life expectancy at birth come mostly from premature mortality.4

The United Nations Children’s Fund analyzes inequity in the rights of children in three key aspects: the right to live, the right to grow healthy and well nourished, and the right to be educated. These aspects are evaluated through an index where 0 is the lowest and 10 the highest. The Mexican state of Guerrero scores the lowest (2.9), while the state of Nuevo Leon scores the highest (8.1). This means that a child born in Guerrero has fewer opportunities to live, grow healthy and be educated than a child born in Nuevo Leon.5

Mexico has four times the average infant mortality rate of developed countries. In 2000, there were 23 infant deaths (children under 12 months) per 1 000 live births, while the average of infant deaths of OECD member countries was 6.5 per 1 000 live births.6 Approximately 40% of infant deaths happen during the neonatal period. In 2010, the rate is 9.6 deaths per 1 000 live births. The rate of infant mortality is 14.2 per 1 000 and the rate of preschool children is 16.7 per 1 000.7 Neonatal mortality represents the risk of death or the survival expectancies of newborns.

Nutritional status of Mexican children

The nutritional status of children is key for their growth and development and has a definitive influence in the trajectory of functional health status in adulthood.8 Malnourished children have poor physical and cognitive development and lower resistance to illness. In a malnourished child, the illness will slow his growth and might progress to more severe forms causing disability and death.9 The short height of stunted children shows the cumulative effect of chronic malnutrition.

Several surveys conducted in Mexico have reported the figures of malnutrition throughout time.10,11 Table I shows that malnutrition has decreased, but persists, thus representing the actual conditions of the vulnerable population.

Overweight is a growing problem in Mexican children.

The proportion of children who are overweight or obese is increasing.12,13 A person who is overweight or obese is at increased risk of diabetes and hypertension.14,15 The 2006 National Health and Nutrition Survey reported a prevalence of 5% of overweight and obesity in preschool children. Another study carried out in children aged 2 years showed that the prevalence of overweight was 4.4% and obesity 2.2% among children living in urban areas, while among rural two-year-olds, the prevalence of overweight was 6.7 and obesity 5.7%.16 The increasing magnitude of this problem among children and its potential long-term consequences make necessary to reinforce preventive activities, among which nutritional education, promotion of physical exercise, and prevention are key elements.17


Anemia is a nutritional disorder mainly due to iron deficiency. Children who suffer from anemia experience developmental delays in motor function, language, cognitive capabilities learning capacities and poor school performance. Furthermore, the immunological responses are also decreased.18,19 Three nation-wide surveys have stressed the magnitude of this problem. Table II shows the prevalence of anemia in these surveys.

These findings show that the prevalence of anemia is decreasing slowly, although a significant percentage of the population continues suffering from this condition. The reduction of anemia is in part due to the effectiveness of different social programs, such as Oportunidades and the routine intervention of the health services that provide iron supplements to both, children and pregnant women.

Infectious diseases

Infectious diseases are still highly prevalent in children, particularly acute diarrhea and respiratory infections. The complications of these diseases (eg: dehydration and pneumonia) are the main causes of deaths among preschool children.

Diarrhea is strongly related to poverty and poor sanitary conditions. Its negative impact is mitigated with proper household treatment and timely healthcare, which in turn depends on efficient access to a medical treatment facility and personnel. The consequences of the number and severity of diarrhea episodes are measurable in the linear growth of the child and in decreased cognitive and physical functions.20

The 2006 National Health and Nutrition Survey (ENSANUT 2006) reported that the prevalence of diarrhea in under-fives was 12.9%, and pointed out important regional differences. The state with the highest prevalence was Chiapas (21.0%) and the lowest was Zacatecas (5.9%). The Ministry of Health (MoH) in Mexico has implemented a significant number of interventions and programs to tackle this public health problem including provision of oral rehydration salts, educational interventions aimed at mothers to provide proper homecare, promotion of exclusive breastfeeding for infants aged 0-6 months, identification of warning signs to seek timely medical care, and provision of vaccines.

The rotavirus vaccine was introduced in Mexico in several phases. In 2006 the vaccine was introduced to impoverished regions of selected states, then, in 2007 it was made available to all children born after February 1st, 2007. The vaccine has been beneficial; its introduction has been associated to a significant decline in diarrhea-related deaths21 and its cost-effectiveness has been demonstrated.22 From the provider’s perspective, development of clinical guidelines, training and updating courses, and provision of necessary supplies have been implemented continuously.

Acute respiratory infections (ARI) are the most prevalent diseases in children under five years. The average child experiences three episodes per year. Children living in poor sanitary conditions, with restricted access to medical care and whose families are unable to afford complete courses of antibiotic treatment are at higher risk of developing complications that increase the risk of death. The basic interventions to decrease the death toll due to lower respiratory infections are: a) proper case management, which includes evidence-based guidelines and proper supply of medications, particularly antibiotics; b) vaccines against HiB, pneumococcus and influenza; in addition, vaccines for diphtheria, measles and pertussis have had a positive impact; c) improvement in children’s nutritional status; and, d) hygienic environment.23 ENSANUT 2006 reported that the prevalence of ARI in children was 50% and asserted that a significant number of complications and deaths due to ARI could be averted if the mother knew the warning signs, and knew to look for medical care. The survey showed that a low percentage of mothers knew what symptoms to look for, and stressed the need to further educational activities at a community level.

Key objectives of health systems

A health system is defined as the set of activities whose purpose is to promote, restore or maintain health.24 In congruence with this definition, the Commission of Social Determinants on Health25 stated that: “The development of a society, rich or poor, can be judged by the quality of its population’s health, how fairly health is distributed across the social spectrum, and the degree of protection provided from disadvantage as a result of ill-health.” The architecture of the Mexican healthcare system is complex and, in the way in which it is currently designed, does not provide fair distribution of services to the population. A growing body of literature is critical about the characteristics of the Mexican health care system and the resultant consequences for the society.26 Taking the perspective of children’s health needs, we will analyze four key aspects of a well-functioning healthcare system: financing, equity, access and quality.


Financing makes possible for all individuals to have access to health care (public health and personal services). That is made possible through raising, pooling and allocating the revenues to purchase healthcare.

The Mexican healthcare system is unfairly financed in a way that does not ensure financial protection for everyone.27 A number of circumstances accounted for this situation. Approximately half of the country’s population was not affiliated with social security services. This demonstrates that households face the risk and uncertainty of not being able to afford medical care in the event that one of its members gets sick. Furthermore, it demonstrates large out-of-pocket expenditures for a healthcare system that still presents a significant percentage of the population
with catastrophically high expenditures.28


Equity in health can be defined as “the absence of systematic disparities in health (or in the major social determinants of health) between social groups who have different levels of underlying social advantage/disadvantage—that is, different positions in a social hierarchy.” Equity should be measurable, and, hence, accountable for actions at policy and programmatic levels.29

Equity is among the top challenges in Mexico because of the wide differences in the health status of various population groups, in the access to health services, and in healthcare financing. The healthcare system in Mexico is not equitable. The insurance coverage for the portion of the population without social security is regressive, and those with coverage face out-of-pocket expenditures for medical treatment, which in turn produce impoverished families. The differences in the health status of Mexican children mentioned earlier demonstrate the need to bridge the gap to reduce inequities.

The fact that a child born in Chiapas has 80% more probability of dying in the first year of life than a child born in Mexico City or in a northern state such as Nuevo Leon or Coahuila clearly indicates the existing disparities.30


Access has a complex framework that comprises several attributes.31,32 Access is defined as the ability of a person to receive health care services, which is a function of: a) availability of personnel and supplies; and, b) ability to pay for the services. Children aged 0-4 years comprise the group that needs and uses healthcare services most often. This includes preventive care visits and ambulatory and hospital care when necessary.

One of the main barriers for access and utilization of services is not having the financial resources. Individuals with health insurance seek medical treatment at the usual source.33 The inequities in access to medical insurance and health financing can result in catastrophic expenditures for families.

The fragmentation of the healthcare system has negatively affected access to healthcare. In response, the Mexican government has implemented a wide variety of programs to improve the access to healthcare mainly to the population that the social security services do not cover. In the late 1990s, different government programs had improved access but with little impact on quality and financing.34 Such policies were focused on implementing programs to expand coverage and provide essential or primary care services Access to proper antenatal care for the pregnant woman, appropriate healthcare during delivery, high quality and appropriate referral and communication between different levels of care are key determinants of newborn health status. The program Arranque Parejo en la Vida is focused on providing information and health care to pregnant women and their newborns.35 Furthermore, economic resources, highly qualified medical personnel and technology are crucial to providing care for preterm infants, infections, and congenital malformations. The resource-constrained Mexican healthcare system severely limits this level of care.


Quality of care is defined as “the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge.”36

For the purposes of this paper, we used the OECD conceptual framework that was defined for the Health Care Quality Indicators Project (HCQI).37

Quality comprises several dimensions focused on effectiveness, safety and patient centeredness. These core elements increase the likelihood of desired health outcomes. Furthermore, to become operational, these dimensions and aspects related to structure, process and outcomes are mentioned briefly.

From the perspective of children’s health, the HCQI only addresses vaccination rates. Its definition is as follows: Vaccination rates reflect the percentage of children at either age 1 or 2 that receives the respective vaccination in the recommended timeframe. Mexico reported 96% of children vaccinated. This percentage was above the average percentage of OECD member countries (92%). Hungary reported the highest percentage (99.9%) and Austria the lowest (79%).38

To our knowledge there are few published experiences addressing quality of care for pediatric patients in Mexico. Some are related to interventions aimed at improving case management of common diseases such as diarrhea and respiratory infections in an effort to decrease childhood mortality due to the complications of these diseases.39,40

Several important health problems must be addressed under the perspective of quality of care. For example, Mexico’s National Health Plan 2007-2012 declared that infant mortality rate had decreased but also stressed the differences among the Mexican states. In the municipalities with lower human development index (HDI) the infant mortality rate was 32.5 while in those with higher HDI, was 15.8. These asymmetries are due to differential access to basic services and differences in the quality of care. The Plan recognizes that 79% of infant deaths are avoidable. In addition, 60% of infant deaths occur in the neonatal period due to respiratory distress, sepsis and prematurity among others. However, there is little information about the quality of care and complications pre-term or newborn infants receive. It is critical to conduct studies aimed at ascertaining better the risk factors of death in premature newborns, and at identifying those that are avoidable by or amenable to effective interventions.

System for Social Protection in Health

The government launched the System for Social Protection in Health (Seguro Popular) in 2003 to offer subsidized, publicly provided health insurance to those within the population without social security to achieve equitable access and coverage of health services. Seguro Popular is the operational component of the health sector reform that had four key objectives: 1) to increase the public spending in health; 2) to stimulate efficient allocation; 3) to protect families from excessive health expenditures; and, 4) to transform the incentives in the system, from the supply side to the demand side.41

Priority was given to poor families, who are entitled to receive an essential package of primary and secondary care interventions that are made known to the enrollees, thus enabling them to request the services and benefits of this insurance scheme. The program is also reinforced by the Fund for Protection against Catastrophic Expenditures, which aggregates the risk of diseases that are of high cost and low prevalence and should be treated at tertiary care facilities.

Seguro Popular
received strong political endorsement and the legislation assured its continuity. The financial resources for Seguro Popular have increased which in turn improve fair financing and equitable distribution of the economic resources among the states, and reduce health expenditures for poor families. For example, the 2008 National Survey of Households’ Income and Expenditures (ENIGH 2008) reported that the proportion of trimester expenditures in health per decile of income decreased from 4.1% to 3.1% in all deciles between the years 2006-2008.42

Medical Insurance for a New Generation

The health of children under the age of five has improved in recent years, however, as was analyzed above, the rates of infant morbidity and mortality are still above international averages. These circumstances fueled the expansion of the benefits of Seguro Popular to children under five years of age. The Federal Government through the Ministry of Health launched the Medical Insurance for a New Generation in 2006.
SMNG is a health care insurance that is financed through taxes. According to the rules of operation, the SMNG main objective is to contribute to decrease impoverishment due to health causes, through universal insurance of all children born after December 2006, who are not affiliated with a social security institution.

SMNG affiliates have benefits of preventive and curative care in primary, secondary and tertiary levels of care since the moment they are registered. Health care services are provided at no charge in three streams a) package of preventive care services; b) laboratory and radiology diagnostic tests) medical care, medications and other medical supplies for specific medical conditions that can be treated in secondary and tertiary care hospitals.

SMNG is expected to boost the achievements of its parent program Seguro Popular. Figure 1 depicts the framework of SMNG: source of funds, sector, system, flow of funds, packages, providers and beneficiaries. Medical services are financially supported by three defined sources of financing for specific medical conditions. a) SMNG funds to provide health care to 128 medical conditions, mostly neonatal illnesses and pre-defined public health interventions: Public health interventions: Pneumococcal and rotavirus vaccines, infant hearing screening, cochlear implants, cold chain, metabolic screening. The Under Secretary of Prevention and Promotion of Health receives the funds that are allocated to the decentralized states Ministries of Health; b) Fund for Protection against Catastrophic Expenditures that finances high-cost, low-prevalence diseases, such as cancer; and c) Universal Catalog of Health Services that comprises the most common ambulatory and hospital care medical conditions. The rules of operation clearly define which are the interventions of these three funds.43

Figure 1. Framework of the Medical Insurance for the New Generation

SMNG aims to strengthen the decentralized MoH capability of the Mexican states to facilitate access to and to provide health care. The program does not affect or duplicate other government programs and interventions regarding the design, benefits, provided support and target population. If the MoH services are unavailable, SMNG will make health care accessible to the children, through agreements reached between SMNG and social security institutions and private providers.

Initially, the strategy of SMNG was to include all children younger than five years that were born after December 2006, and who were not affiliated with social security. It is expected that SMNG will cover all children without social security by 2012. Affiliation with SMNG is voluntary and offered after the child is born. Once the child is affiliated, the other members of the family must be affiliated with Seguro Popular.

The objectives of SMNG are:

• To reduce the incidence of diseases and disability
• To promote preventive care and ensure comprehensive coverage of health care.
• To reduce neonatal mortality
• To reduce morbidity and mortality of infant and preschool children
• To foster healthy growth and development.
• To provide health services, including medications that respond to the epidemiological profile, health needs and demands for health care.
• To prevent the impoverishment of families derived from expenditures on health care for children under 5 years.

Its rules of operation state that SMNG should be monitored and evaluated continuously. The evaluation is conceptualized as a continuous and systematic process that, along with monitoring activities, will allow identification of its achievements and limitations. The evidence gathered through the evaluation would lead to adjustments and implementation of interventions aimed at improving SMNG performance.

Improvement of child health has driven policies that are operationalized in a number of programs and interventions. It has been criticized that most programs are focused on medical aspects, such as preventive and curative care to reduce morbidity and mortality and other environmental and social factors are being neglected.44 In Mexico there are several programs addressing social needs of children and their mothers, such as the program Oportunidades which is an anti-poverty program focused in poor rural and urban families. This is a conditional cash-transfer program aimed at improving societal conditions and decrease poverty. The program has proven to be successful in promoting better growth of children.45,46

The increase in funds SMNG is a program that can contribute to decrease the burden of disease in children under five years old and alleviate health expenses of families who must care for sick children. SMNG has the legal, financial and organizational mechanisms that will facilitate its operation. The evaluation of the program in terms of the achievement of its objectives will be central groundwork to developing evidence-based public policies aimed at improving the health of Mexican children and would provide valuable lessons for other healthcare systems aimed at developing or strengthening their systems for social protection of health.


The realization of this evaluation was achieved thanks to the financial support from the Sistema Nacional de Protección en Salud and the Seguro Médico para una Nueva Generación.
