This paper proposes structural interventions to organize the working population which could be implemented to avoid a new wave of Covid-19 cases without halting economic activity. We summarize the evidence regarding cyclic schedules of work days followed by days in lockdown. We discuss the possible application of cycles of four days of work followed by three in lockdown for the Mexican context. We also discuss two complimentary interventions for these cycles: continuing to work from home for the sectors for which this is possible and staggered work shifts. This discussion takes into account the high informality context and the scarcity of resources to absorb productivity losses in middle and small companies. We consider the need to implement financial help for people and companies to mitigate lost earnings both in the formal and in the informal work sectors. [ABSTRACT FROM AUTHOR]

Bisphenol A (BPA), found in plastics and epoxy resins, is one of the most studied chemicals. BPA is regarded as an endocrine disruptor and has been related to adverse health effects in humans. However, some regulatory agencies around the world have concluded that BPA is safe at current human exposure levels. As the scientific community attempts to settle the debate on BPA's health effects, regulatory agencies have been put into a challenging public health policy situation. The United States has implemented no regulatory actions due to safety concerns, while Europe has used the precautionary principle to guide its regulation in the face of scientific uncertainty. In this paper, we explore the debate surrounding BPA regulation and the possibility for countries to introduce guidelines, using Mexico as an example. Policy change determinants analysis suggest that countries can and should impose regulations on BPA. [ABSTRACT FROM AUTHOR]

Objective. To describe the methodological design of the National Health and Nutrition Survey in localities with less than 100 000 inhabitants (Ensanut 100k). Materials and methods. The Ensanut 100k is a probabilistic survey that over-represents households with less economic capabilities. This paper describes the scope of the survey, sampling procedures, measurement and inference and logistics organization. Results. 10 461 home interviews and 26 161 individual interviews were obtained. The household response rate was 89 and 92% from individuals. Conclusions. The probabilistic design of the Ensanut 100k allows to make valid statistical inferences about parameters of interest for public health in localities with less than 100 000 inhabitants, localities where 52% of the population lives according to the 2010 census. The comparability of the results with the Ensanut 2012 facilitates the assessment of the government's support actions to populations with lower economic capacities in the period 2012-2018.

This paper describes the creation of the legal framework and the origin, growth and consolidation of the institutions and interventions (initiatives, programs and policies) that nourished public health in Mexico in the past century. It also discusses the recent efforts to guarantee universal social protection in health. This quest, which lasted a century, developed through three generations of reform that gave birth to a health system that offers protection against sanitary risks, protection of health care quality and financial protection to all the population in the country.

Some interpretations frequently argue that three Disability Models (DM) (Charity, Medical/Rehabilitation, and Social) correspond to historical periods in terms of chronological succession. These views permeate a priori within major official documents on the subject in Mexico. This paper intends to test whether this association is plausible by applying a timeline method. A document search was made with inclusion and exclusion criteria in databases to select representative studies with which to depict milestones in the timelines for each period. The following is demonstrated: 1) models should be considered as categories of analysis and not as historical periods, in that the prevalence of elements of the three models is present to date, and 2) the association between disability models and historical periods results in teleological interpretations of the history of disability in Mexico.

Depression is an important public health problem. It is the fourth cause of disease in the world in terms of lost years of healthy life. In Mexico, it ranks first in terms disability for women and ninth for men. There is a high comorbidity between depression and other mental disorders such as anxiety and substance abuse, as well as other serious and chronic physical conditions (e.g. diabetes, and heart disease). Despite the impact of depressive disorders in the quality of life of the population, there is a large proportion of people who don't get treatment, delaying seeking help and thus don't receive adequate assistance. The aim of this paper is to present an analysis of depression status in the Mexican population from a public health perspective; it includes prevalence and associated factors, gaps in care, characteristics of the use of services and treatments available. The paper concludes with a presentation of the implications for research and mental health policy in Mexico. [ABSTRACT FROM AUTHOR]

The decreasing breastfeeding rate in México is of public health concern. In this paper we discus an innovative regulatory approach -Performance Based Regulation- and its application to improve breastfeeding rates. This approach, forces industry to take responsibility for the lack of breastfeeding and its consequences. Failure to comply with this targets results in financial penalties. Applying performance based regulation as a strategy to improve breastfeeding is feasible because: the breastmilk substitutes market is an oligopoly, hence it is easy to identify the contribution of each market participant; the regulation's target population is clearly defined; it has a clear regulatory standard which can be easily evaluated, and sanctions to infringement can be defined under objective parameters. Recommendations: modify public policy, celebrate concertation agreements with the industry, create persuasive sanctions, strengthen enforcement activities and coordinate every action with the International Code of Marketing of Breast-milk Substitutes.

Objective. This paper explores the impact of contextual variables at the neighborhood level on a health marker in the city of Hermosillo, Mexico and discusses the importance of collaboration between planners and health professional to minimize the negative effect of contextual factors on urban health. Materials and methods. Few studies in Mexico have assessed health outcomes at the intra-urban scale and their interaction with neighborhood-level contextual variables. Using spatial analysis and geographical information systems, the paper explores the association between infant mortality and an index of socio-environmental vulnerability used to measure urban contextual factors. Results. Two high infant mortality clusters were detected within neighborhoods characterized by relatively good environmental conditions and one in a neighborhood with a poor environment. Conclusions. Our results show the clustering of high infant mortality areas and some association with built environment factors in Hermosillo. The results support the need to reconnect public health and urban planning as a way to create healthier environments in Mexican cities. [ABSTRACT FROM AUTHOR]

This paper describes the Mexican health system. In part one, the health conditions of the Mexican population are discussed, with emphasis in those emerging diseases that are now the main causes of death, both in men and women: diabetes, ischaemic heart disease, cerebrovascular diseases and cancer . Part two is devoted to the description of the basic structure of the system: its main institutions, the population coverage, the health benefits of those affiliated to the different heath institutions, its financial sources, the levels of financial protection in health, the availability of physical, material and human resources for health, and the stewardship functions displayed by the Ministry of Health and other actors. This part also discusses the role of citizens in the monitorization and evaluation of the health system, as well as the levels of satisfaction with the rendered health services. In part three the most recent innovations and its impact on the performance of the health system are discussed. Salient among them are the System of Social Protection in Health and the Popular Health Insurance. The paper concludes with a brief analysis of the short- and middle-term challenges faced by the Mexican health system. [ABSTRACT FROM AUTHOR]

Objective. This paper critically examines recent work on qualitative health research (QHR) in Mexico. Material and Methods. A review was conducted of 128 articles published between 2000 and 2009. A literature search was done drawing together a verse of indexes, search engine, data bases and citations, as well as interviewing researchers. A frequency and content analysis was carried out. Results. QHR has expanded significantly, both nationally and internationally, and papers published in public health and social medicine journals. However, several factors impede its consolidation: the institutional, territorial and thematic concentration of studies, the dependency on grounded theory, the selective nature of the research topics and populations; and its marginal scientific impact. Conclusions. QHR has grown in México, but its consolidation faces serious challenges. Several proposals are discussed that could strengthen the field. [ABSTRACT FROM AUTHOR]

The present paper reflects on utilization of the gender category in food and nutrition studies in Mexico. It highlights women's important role as caretakers of family health and nutrition. Briefly the authors review how women have been analysed in the different food an nutrition surveys; how gender has been effaced in the "mean per capita", and how women have been taken into account only as far as their reproductive role. This paper also outlines the importance of including the gender category and gender approach in food and nutrition studies; in order to clearly visualize the feeding inequities among men and women throughout the stages of the feeding process, i.e. decision, provision, preparation, distribution and intake. Moreover, improved understanding of women's nutrition practices and meanings that foods convey to women is advocated. In the conclusion the absolute need to articulate the gender issue in nutrition, nursing and medical academic curricula is stated. [ABSTRACT FROM AUTHOR]

During the past six years, Mexico has undergone a large-scale transformation of its health system. This paper provides an overview of the main features of the Mexican reform experience. Because of its high degree of social inequality, Mexico is a microcosm of the range of problems that affect countries at all levels of development. Its health system had not kept up with the pressures of the double burden of disease, whereby malnutrition, common infections, and reproductive health problems coexist with non-communicable disease and injury. With half of its population uninsured, Mexico was facing an unacceptable paradox: whereas health is a key factor in the fight against poverty, a large number of families became impoverished by expenditures in health care and drugs. The reform was designed to correct this paradox by introducing a new scheme called Popular Health Insurance (Seguro Popular). This innovative initiative is gradually protecting the 50 million Mexicans, most of them poor, who had until now been excluded from formal social insurance. This paper reports encouraging results in the achievement of the ultimate objective of the reform: universal access to high-quality services with social protection for all. [ABSTRACT FROM AUTHOR]

Objective. This paper describes the study design and baseline characteristics of the study population, including the first 30 829 women who enrolled in the Forwarding Research for Improved Detection and Access for Cervical Cancer Screening and Triage (FRIDA Study). This is a large population based study that is evaluating the performance and cost-effectiveness of different triage strategies for high-risk HPV (hrHPV) positive women in Mexico. Materials and methods. The target population is more than 100 000 women aged 30 to 64 years who attend the Cervical Cancer Screening Program in 100 health centers in the state of Tlaxcala, Mexico. Since August 2013, all women in the region have been invited to enroll in the study. The study participants are evaluated to determine hrHPV infection using the Cobas 4800 HPV test. The HPV-16/18 genotyping and cytology triage strategies are performed as reflex tests in all hrHPV-positive participants. Women with a positive HPV-16/18 test and/or abnormal cytology (atypical squamous cells of undetermined significance or worse, ASCUS+) are referred for colposcopy evaluation, where a minimum of four biopsies and an endocervical sample are systematically collected. Histologic confirmation is performed by a standardized panel of pathologists. Results. Among the 30 829 women who have been screened, the overall prevalence of hrHPV is 11.0%. The overall prevalence of HPV16 and HPV18 are 1.5% and 0.7%, respectively. Cytological abnormalities (ASCUS+) were detected in 11.8% of the hrHPV-positive women. A total of 27.0% (920/3,401) of the hrHPV-positive women were referred to colposcopy because of a positive HPV16/18 test and/or abnormal reflex cytology, (31.6% had only ASCUS+, 53.6% were HPV16/18 positive with a normal cytology result, and 9.5% were positive to both triage tests). Conclusion. The results of this study will help policy makers and health service providers establish the best practices for triage in cervical cancer screening in Mexico and other countries.

Objective. This paper describes the 2001-2012 progression of limitations in daily activities in the Mexican elderly population aged 60 or older and identifies how sociodemographic and health factors affect these progressions. Materials and methods. Data come from the Mexican Health and Aging Study (MHAS), a national sample of adults born in 1951 or earlier, including a baseline survey in 2001 and follow-ups in 2003 and 2012. Results. Difficulty in getting dressed is the activity that has the highest prevalence in all three waves for both genders. In the 11 -year transition, 42.8% of the respondents with no limitations in 2001 reported no limitations in 2012. In contrast, 60.8% of those who reported three or more limitations in 2001 had died by 2012. Conclusions. With the rapid aging of the Mexican population, the knowledge of patterns of deterioration of functional limitations will prove useful for future public health policies. [ABSTRACT FROM AUTHOR]

The right to health and its operational form, as an organized social response to health: the right to health protection, are the mainstay for the global push towards universal health coverage. The path to achieve this goal is particular to each country and relates to the baseline and specific context in relation to what is feasible. In practical terms, universal coverage involves the correlation between demand and supply of services (promotion, prevention, and care), expressed by the ability for each individual to make use of services when these are required. In those terms universal coverage is then effective access. The objective of the paper is to explore the conceptualization of effective access to health services and propose a definition that allows its operationalization thereof. This definition considers key elements of supply and demand of services, including the availability of resources and adequate provision (quality), as well as barriers to use them.

Listeriosis is caused by Listeria monocytogenes, an important food-borne disease due to its clinical forms, high mortality rate, and the economic impact in both clinical and food production industries. In Mexico, the lack of epidemiological surveillance systems leads to the need of accurate data on the incidence of listeriosis and its association with food-borne disease. In this paper, we present data about the presence of this bacterium in food, reports related to clinical cases of listeriosis, and information of diseases in which L. monocytogenes may be involved. However, in most of these cases the etiology was not established. Given this, there's a need to inform and warn the appropriate entities, to define strategies for the mandatory search of L. monocytogenes through the whole food production chain and clinical suspects, for the epidemiological importance and control of listeriosis in Mexico.

Objective. To evaluate technical efficiency and potential presence of scale and scope economies in Mexican private medical units (PMU) that will improve management decisions. Materials and methods. We used data envelopment analysis methods with inputs and outputs for 2 105 Mexican PMU published in 20l0 by the Instituto Nacional de Estadística y Geografía from the "Estadística de Unidades Médicas Privadas con Servicio de Hospitalización (PEC-6-20-A)" questionnaire. Results. The application of the models used in the paper found that there is a marginal presence of economies of scale and scope in Mexican PMU. Conclusions. PMU in Mexico must focus to deliver their services on a diversified structure to achieve technical efficiency. [ABSTRACT FROM AUTHOR]

Objective. This paper describes the methods and key findings of formative research conducted to design a school-based program for obesity prevention. Materials and methods. Formative research was based on the ecological model and the principles of social marketing. A mixed method approach was used. Qualitative (direct observation, indepth interviews, focus group discussions and photo-voice) and quantitative (closed ended surveys, checklists, anthropometry) methods were employed. Results. Formative research key findings, including barriers by levels of the ecological model, were used for designing a program including environmental strategies to discourage the consumption of energy dense foods and sugar beverages. Conclusion. Formative research was fundamental to developing a context specific obesity prevention program in schools that seeks environment modification and behavior change. [ABSTRACT FROM AUTHOR]

Objective. This paper focuses on public and private healthcare utilization among dependents living in Mexico of Mexican migrants in California, analyzing the link between remittances and enrollment in Seguro Popular, a social health insurance plan. Materials and methods. We surveyed 1 353 migrants who visited the Mexican consulate of Los Angeles in 2010. Results. 53.9% sent remittances; 72.2% of households receiving remittances used a share of remittances for health care and 74.4% of them were covered by Seguro Popular. The annual median with private health care expenditure was USD 825, compared to USD 293 for public providers. The main predictors remittances utilization for healthcare were having a sick dependent, purchase of prescription drugs, experiencing problems paying for health care and time of U.S. residence. Conclusions. Seguro Popular increases healthcare utilization with public providers, which provides an opportunity to reallocate the use of migrant's remittances for health purposes.

Objective. This paper describes the rationale, design, and methods of a two-year randomized controlled trial conducted to evaluate the effectiveness of an environmental intervention in 27 elementary schools in Mexico City. Materials and methods. There were two units of analysis, school level addressing changes in elementary public part-time schools, and individual-level addressing behavioral changes in students 9 to 11 years of age. Two intensities of an intervention program were implemented (basic and plus), each containing two intervention components: physical activity and nutrition, supported by a communication/education component. Evaluation of the intervention was carried out during the school cycles 2006-2007 and 2007-2008. Results. Primary outcomes were overweight and obesity prevalence and fitness; environmental and behavioural measures were also examined. Conclusions. This is the first institutional multilevel, multifactorial project, consistent with the best practices available in current literature, carried out in Mexico to prevent childhood obesity in schools.

The reforms made in recent years to the Mexican Health System have reduced inequities in the health care of the population, but have been insufficient to solve all the problems of the MHS. In order to make the right to health protection established in the Constitution a reality for every citizen, Mexico must warrant effective universal access to health services. This paper outlines a long-term reform for the consolidation of a health system that is akin to international standards and which may establish the structural conditions to reduce coverage inequity. This reform is based on a "structured pluralism" intended to avoid both a monopoly exercised within the public sector and fragmentation in the private sector, and to prevent falling into the extremes of authoritarian procedures or an absence of regulation. This involves the replacement of the present vertical integration and segregation of social groups by a horizontal organization with separation of duties. This also entails legal and fiscal reforms, the reinforcement of the MHS, the reorganization of health institutions, and the formulation of regulatory, technical and financial instruments to operationalize the proposed scheme with the objective of rendering the human right to health fully effective for the Mexican people.

Unlike many other Latin American countries Mexico has no coherent and explicit national pharmaceutical policy (NPP). Other national challenges are: high out-of-pocket expenditure on medicines despite the implementation of universal health care coverage through Seguro Popular, high prices of medicines in the private sector in comparison to other countries when adjusted for income level, and the lack of clear strategies to improve safety and efficiency in the use of medicines, in particular interventions aimed at private physicians, pharmacies and consumers. The aim of this paper is to describe the challenges and opportunities to (1) consolidate the processes of formulating, implementing and evaluating NPP, and (2) define the policy content with regard to access and use of medicines.

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.

Objective. This paper assesses the quality of the underlying cause of death (COD) statistics in Hermosillo, Mexico in a random sample of 300 in-hospital adult deaths. Material and Methods. A "gold standard" COD, determined by a systematic review of hospital medical charts, was compared to the COD reported by the vital registry system. Results. Overall agreement between the reviewer and original COD at the ICD-10 chapter block was 69.2%, with a weighted kappa of 0.62. Agreement varied greatly by ICD-10 chapter . Mutual misclassification among common co-morbidities, such as diabetes mellitus and circulatory disease, minimized the net change in the mortality fraction assigned to each ICD-10 chapter after physician review. Conclusions. The ICD-10 chapter level underlying COD codes can be used to estimate disease burden in the population. Caution is recommended for use of vital registry statistics in Hermosillo for individual level or disease-specific analyses. [ABSTRACT FROM AUTHOR]

Objective. To estimate the optimum size for hemodialysis units to maximize production given capital constraints. Materials and Methods. A national study in Mexico was conducted in 2009. Three possible methods for estimating a unit's optimum size were analyzed: hemodialysis services production under monopolistic market, under a perfect competitive market and production maximization given capital constraints. Results. The third method was considered best based on the assumptions made in this paper; an optimal size unit should have 16 dialyzers (15 active and one back up dialyzer) and a purifier system able to supply all. It also requires one nephrologist, five nurses per shift, considering four shifts per day. Conclusion. Empirical evidence shows serious inefficiencies in the operation of units throughout the country. Most units fail to maximize production due to not fully utilizing equipment and personnel, particularly their water purifier potential which happens to be the most expensive asset for these units.

Estimation of the burden of disease attributable to smoking has now become standard in documenting the impact of the tobacco epidemic and in motivating tobacco control. This paper addresses the methods used to estimate the attributable burden of mortality and the related estimation of morbidity and economic costs. Estimates of attributable mortality and morbidity for the Americas range widely, reflecting the maturity of the tobacco epidemic. The estimates are highest for the United States, and lower for Mexico and other countries of the Americas. [ABSTRACT FROM AUTHOR]

Breast Cancer is a significant public health problem associated with epidemiological and demographic transitions that are currently taking place in Mexico. Aging and increased exposure to risk factors are thought to increase breast cancer incidence, having great relevance for the society and health services. Under this scenario, the health system must respond to the growing needs for better breast cancer screening services. In this paper we present an update of breast cancer mortality, general international recommendations for breast cancer screening programs and key aspects of the Mexico Action Program for Breast Cancer Screening and Control 2007-2012. Breast cancer policies are aimed at organizing and increasing the infrastructure to develop a National Program for Detection, Diagnosis and Treatment of Breast Cancer with optimal quality, friendliness and respect for patient’s rights.

Breast cancer is a serious threat to the health of women globally and an unrecognized priority in middle-income countries. This paper presents data from Mexico. It shows that breast cancer accounts for more deaths than cervical cancer since 2006. It is the second cause of death among women aged 30 to 54 and affects all socioeconomic groups. Data on detection, although underreported, show 6 000 new cases in 1990 and a projected increase to over 16 500 per year by 2020. Further, the majority of cases are self-detected and only 10% of all cases are detected in stage I. Mexico ́s social security systems cover approximately 40 to 45% of the population and include breast cancer treatments. Since 2007 the rest of the population has had the right to breast cancer treatment through Seguro Popular. Despite these entitlements, services are lacking and interventions for early detection, particularly mammography, are very limited. As of 2006 only 22% of women aged 40 to 69 reported having a mammography in the past year. Barriers exist on both the demand and supply sides. Lobbying, education, awareness building and an articulated policy response will be important to ensure extended coverage, access to and acceptance of both treatment and early detection.

The purpose of this paper is to organize and summarize existing information on delayed medical attention for women with breast cancer and identify research needs in this area. This review is organized in six parts: origins and permanence of the message “do not delay” medical attention for potential cancer symptoms; definition and classification of breast cancer delay; impact of delay on breast cancer prognosis; factors related to breast cancer delay and the ways these have been studied; the study of breast cancer delay in Mexico; and directions for future research in developing countries, with a special focus on Mexico. We point out the need of a more integral study of delay that takes into account socio-structural and health services factors, in order to find modifiable factors towards which political actions should be directed to improve breast cancer medical attention in underdeveloped countries.

Not always public policies for the advocacy of citizen rights meet their goal, among other things, because between their formulation and their implementation there is a lack of appropriate structures to generate, articulate and execute these policies. This has been the case of Mexico regarding the advocacy of the rights of non smokers. Very few has been achieved in this matter in the past. This article lists some of the potential causes of the lack of implementation of public policies. At the same time, explores the highly dynamic nature of the health care system at the present and towards the future. The magnitude of the challenges faced by the health care system requires concerted actions of many actors, not only from the very health care system but also from outside. Thus, public policies have to be considered not just at the governmental level but at the state level. Therefore, the main argument of this paper is that given the need to respond to complex challenges to protect the health of the population and their rights in a very complex context, there is a need to formulate and implement state policies that require the intervention of the appropriate state structures to make sure that the design and execution leads to the expected achievements. One such structure at the state level, among others, is the General Health Council, an organization established in 1841, that was incorporated within the Mexican Constitution in 1917, depending directly from the President of Mexico as Head of State. This Council has been reinforced to improve its assigned role to better participate, along other state structures, in the formulation and implementation of public policies such as those for the advocacy of citizen rights.

Objective. To initiate a statewide expanded metabolic screening program in neonates with the purpose of identifying the most common inborn errors of metabolism. Material and Methods. From March 2002 through February 2004, a blood sample was obtained between 24 and 48 hours after delivery from every consecutive child born in public hospitals in Nuevo León. It was spotted on filter paper and analyzed by tandem mass spectrometry for expanded metabolic screening. Results. A total of 42 264 samples were analyzed. Were obtained seven positive results, one for each disorder: homocystinuria, hyperphenylalaninemia, citrulinemia, transient tyrosinemia, 3-methylcrotonyl CoA carboxylase deficiency, 3-hydroxy-3-methylglutaryl CoA deficiency, and classic galactosemia. Conclusions. The estimated incidence of inborn errors of metabolism is 1:5 000, with a false positive rate of 0.22%. The program permitted the identification of metabolic disorders in the newborn, allowing an early intervention and prevention of life-threatening events and permanent neurological damage.

Objective. To show the prevalence of diabetes mellitus (DM) and its associated factors in adults, using data derived from the 2000 National Health Survey (NHS). Material and Methods. The 2000 NHS was conducted between November 1999 and June 2000. An adult questionnaire was administered to 45 294 subjects 20 years of age and older. Capillary glucose levels, weight, height and blood pressure were obtained. Individual weighted factors were considered in the statistical analysis, as was the survey's complex sampling design to obtain variances using SUDAAN 7.5.6. Results. The national prevalence of DM in adults ages 20 years and older was 7.5% (95% CI: 7.1-7.9). The prevalence was 7.8% in women and 7.2% in men. It was higher according to age: 2.3% in adults 40 years or younger and 21.2% in those older than 60 years of age. In the urban population, prevalence was 8.1% and in the rural population it was 6.5%. The disease was more frequent in the northern region of the country (8.4%) and in the Mexico City metropolitan area (8.1%). DM was more frequent in the population with the least amount of schooling (9.9%), the lowest income (8.1%), high blood pressure (13.7%), hypercholesterolemia (23.3%) microalbuminuria (15.5%) and renal disease (12.3%). Using multivariate logistic regression, stratified by gender, variables associated with DM were identified: age, little schooling, family history of DM, high blood pressure, renal disease or hypercholesterolemia in both genders. Abdominal obesity was associated with DM in women only and living in an urban area was associated with DM only in men. The highest associations were observed with age, family history of DM, and microalbuminuria. Conclusion. Results from the 2000 NHS show that DM represents a serious public health problem in Mexico. The impact increases when DM affects populations with social or economic factors that limit access to treatment. Data reported in this paper are useful to the implementation of screening and prevention programs. These results confirm that DM should be screened in first-degree family members and everyone who has one or more metabolic syndrome components (high blood pressure, dyslipidemia, obesity and microalbuminuria) [ABSTRACT FROM AUTHOR]

Objective. To report the comparative results of the sub-sample of fasting adults selected for the biochemical measurement of cardiovascular risk factors and the rest of the Mexican Health Survey (MHS) (2000) participants. Material and Methods. The nationally representative, cross-sectional Mexican Health Survey (2000) was analyzed. Survey participants reporting a fasting state period of 9- to 12-h were included in a sub-sample (n= 2 535) and compared with all other participants (n= 41 126). Prevalence and 95% confidence intervals (95%CI) were calculated for socio-demographic, anthropometric, health and personal background characteristics and compared between groups using Pearson X² to determine significant differences. Mean and 95%CI and a T-test were calculated to analyze continuous variables. Results. From the 45 294 adults participating in the MHS, 5.59% were at fasting state. The fasting sub-sample (FS) had a higher male-to-female ratio and was on average 3.5 years younger than the non-fasting participants (NF) and had a 1.5cm wider average waist circumference. No differences were found in location, country region, socio-economic status, indigenous population, or literacy. Also, no differences were found in weight, height, BMI, systolic and diastolic blood pressure, prevalence of diabetes mellitus, previous medical diagnosis of dislypidemias, or tobacco or alcohol consumption. Conclusion. This paper documents the characteristics of the fasting sub-sample from the Mexican Health Survey (MHS). Overall, the non-fasting participants had no relevant differences that can contribute to generate biased results in the analysis of biochemical indicators of cardiovascular risk.

Objective. The aim of this paper is to present findings from the GYTS on current cigarette smoking and other tobacco epidemic indicators. Material and Methods. The GYTS uses a two-stage cluster sample survey design that produces representative samples of students aged 12 to 15 years enrolled in public, private and technical schools. The survey was undertaken in 2003 and 2006 at 399 schools in nine cities. The GYTS surveyed 33 297 students. Point prevalence, differences of proportions and adjusted odds ratio were estimated. Results. The overall rate for current smoking in 30 days preceding the survey is 24.9% (95% CI, 22.5-27.3). Among never smokers, 28% are likely to initiate smoking next year. As compared to the previous survey in 2003, there is not a reduction in cigarette smoking or exposure to secondhand smoke. Cessation rates have not changed and advertisements and access by minors to tobacco products are still unresolved problems. However, tobacco related materials have significantly been added to school curricula. National estimates are presented, as well as city level estimates. Conclusion. Two years after FCTC ratification, there is no major improvement in critical areas of tobacco control in Mexico; particularly, there is no evidence of reduction in cigarette smoking among students in secondary schools.

Despite having achieved an average life expectancy of 75 years, much the same as that of more developed countries, Mexico entered the 21st century with a health system mared by its failure to offer financial protection in health to more than half of its citizens; this was both a result and a cause of the social inequalities that have marked the development process in Mexico. Several structural limitations have hampered performance and limited the progress of the health system. Conscious that the lack of financial protection was the major bottleneck, Mexico has embarked on a structural reform to improve health system performance by establishing the System of Social Protection in Health (SSPH), which has introduced new financial rules and incentives. The main innovation of the reform has been the Seguro Popular (Popular Health Insurance), the insurance-based component of the SSPH, aimed at funding health care for all those families, most of them poor, who had been previously excluded from social health insurance. The reform has allowed for a substantial increase in public investment in health while realigning incentives towards better technical and interpersonal quality. This paper describes the main features and initial results of the Mexican reform effort, and derives lessons for other countries considering health-system transformations under similarly challenging circumstances.

Violence against women by partners (VAWP) has been systematically studied in Mexico in the past 15 years. The aim of this paper is to reflect on the contributions on this topic in Mexico. The discussion focuses on the magnitude of this phenomenon, stressing its theoretical, methodological, and technical implications; the relationship between violence and a variety of factors; and the outcomes of VAWP on women themselves. The manuscript features the main contributions from quantitative and qualitative studies. [ABSTRACT FROM AUTHOR]
