This paper describes the Venezuelan health system, including its structure and coverage, financial sources, human and material resources and its stewardship functions. This system comprises a public and a private sector. The public sector includes the Ministry of Popular Power for Health (MS) and several social security institutions, salient among them the Venezuelan Institute for Social Security (IVSS). The MH is financed with federal, state and county contributions. The IVSS is financed with employer, employee and government contributions. These two agencies provide services in their own facilities. The private sector includes providers offering services on an out-of-pocket basis and private insurance companies. The Venezuelan health system is undergoing a process of reform since the adoption of the 1999 Constitution which calls for the establishment of a national public health system. The reform process is now headed by the Barrio Adentro program.

Background/Objective: Insulin resistance (IR) is a metabolic disorder that is increasing worldwide and has been associated with several negative health outcomes. The aim of this study was to evaluate the relationship between different dietary patterns and IR among Mexican children and adolescents. Methods: We performed a cross-sectional analysis on baseline data from Mexican children and adolescents aged 7-18 years participating in the Health Workers Cohort Study. We included 916 children and adolescents of both sexes. Fasting serum glucose and insulin levels were determined by standardized methods. We defined IR using the homeostasis model assessment (HOMA) as ≥ 3.5. Factor analysis was used to identify dietary patterns. The associations of interest, those between IR and dietary patterns, were analyzed with multiple logistic regression models. Results: IR prevalence was 20.3% among girls and boys aged 7-18 years, for whom the prevalence of overweight and obesity was 29.7%. We identified 3 major dietary patterns in this group: 'Western', 'prudent' and 'high protein/fat'. For the purposes of this analysis we compared the upper versus the lower quintile of each dietary pattern. Independently of other covariates, participants in the highest quintile of the Western pattern had 92% greater odds of IR (OR 1.92, 95% CI: 1.08-3.43) compared with those in the lowest quintile. Conclusions: These findings support the hypothesis that high carbohydrate diets like our Western dietary pattern may increase IR in young people. This result emphasizes the importance of preventive nutrition interventions geared toward Mexican children and adolescents. Copyright © 2012 S. Karger AG, Basel.

Introduction: Recently there has been interest in the possible role of intestinal microbiota as enhancing agent of the rapid increase being observed in the increased prevalence of obesity worldwide. Objectives: To relate the changes may cause the consumption of antibiotics in the intestinal microbiota with obesity. Methods: Were extracted from the National Health Survey of Spain, between 2001 and 2011, the numbers of intake of antibiotics and the prevalence (%) of obesity in the same age range, gender and year. The mean total respondents was 29,904 participants. Results: Signifi cant correlations (p = 0.09) in the association of the prevalence of obesity and intake of antibiotics were found. Furthermore, in order that this infl uence males it is twice that in women. Conclusions: The recent discoveries in the fi eld of intestinal microbiota and its relationship with the host break new ground in the understanding of certain infl ammatory and metabolic diseases such as obesity. © 2016, Grupo Aula Medica S.A.

Objective. The present study aims to describe the prevalence, distribution and trends of hypertension (HT) in Mexican adults =20 years, and to describe the prevalence of early diagnosis and treatment of HT. Materials and methods. A total of 10 898 adults were considered. The measurement of blood pressure was performed following the procedures recommended by the American Heart Association. An adult was considered, hypertensive when he met the diagnostic criteria of JNC-7. Results. The prevalence of HT was 31.5%, of which 47.3% were unaware of their condition. Pharmacological treatment was not associated with a higher percentage of subjects under control. Conclusion. Prevalences from 2000, 2006 and 2012 suggest that there is a stabilization. A health problem of this magnitude requires better diagnosis, care and training of the medical sector so that appropriate treatments are prescribed and HT control can be enhanced.

We carried out this study to compare the effect of consuming whole, partially defatted and defatted cows' milk for 4 months on serum concentrations of blood indicators of cardiovascular risk (CVR) in Mexican children and adolescents. Children aged between 6 and 16 years living in indigenous boarding schools in Mexico and who were usual consumers of whole milk were recruited to this study. Totally, thirteen boarding schools were randomly selected to receive full supplies of whole, partially defatted and defatted cows' milk for 4 months. Serum total cholesterol (TC), TAG, HDL-cholesterol, apoA and total apoB, and Lp(a) concentrations were measured before and after the intervention. Comparisons were made with multi-level mixed-effects linear regression models using the difference in differences approach. Compared with the whole milk group, TC, LDL-cholesterol, HDL-cholesterol and total apoB were lower in defatted milk consumers by -0·43, -0·28, -0·16 mmol/l and -0·05 g/l, respectively (all P<0·001). Compared with the whole milk group, the group that consumed partially defatted milk showed a significant decrease in the concentrations of LDL-cholesterol (-0·12, P=0·01), apoA (-0·05 g/l, P=0·01) and total apoB (-0·05 g/l, P=0·001). Defatted milk intake for 4 months reduced some of the serum indicators of CVR. © 2015 The Authors.

Objective. To estimate the effects of physical activity (PA) and obesity on the cumulative incidence of disability on the basic activities of daily living in the elderly. Materials and methods. Longitudinal study. We selected 2477 participants aged 65-74 years from the impact evaluation study of a non-contributory pension program in Mexico. Participants were without disability at baseline. Katz index was used to assess disability both at baseline and follow-up. PA, body mass index, and covariates were measured at baseline. Results. After 14-months of follow-up, the cumulative incidence of disability reached 10.1%. High PA was found to reduce disability risk (OR=0.64; 95%CI [0.43-0.95]), and the association between obesity and disability was marginally significant (OR=1.36; 95%CI [0.96-1.95]). Conclusions. There is a need to perform a functional assessment of older adults in primary care to identify patients with functional dependence , and to promote physical activity to maintain muscle mass and thus reduce the incidence of disability.

Mexico is facing an unprecedented epidemic of obesity and overweight, especially among children. This paper seeks to identify the main social representations related to school meals present in the discourse of different actors within the schools. Twenty interviews with school staff and ten discussion groups with boys and girls from 12 schools were conducted. Three main conceptions were identified in relation to school meals: 1) junk food vs. homemade food; 2) different perspectives on the importance of eating fruit; and 3) the enjoyment experienced while eating at school. The contribution of this information towards a better understanding of the mealtime supply of the schools and the demand of the students is discussed. This study also permits the identification of certain elements which profoundly structure the relationships of different school actors to school feeding, which are based on: 1) Ideas about nutrition generated by different and sometimes contradictory fields of knowledge, demonstrating the dynamicity and complexity of the practice of eating: 2) children's understandings about how to classify and prioritize foods; and 3) the connections between food and cultural identity.

Objective. To describe the prevalence of iron, folate, and B12 deficiencies in Mexican women of reproductive age from the National Health and Nutrition Survey (Ensanut) 2012. Materials and methods. Data came from a national probabilistic survey, representative from rural and urban areas, and different age groups. Blood samples were obtained from 4 263, 20 to 49 years old women for serum ferritin, vitamin B12 and serum folate concentrations. The prevalence of deficiencies, was assessed using adjusted logistic regression models. Results. The deficiency of folate was 1.9% (95%CI 1.3-2.8), B12 deficiency was 8.5% (95%CI 6.7-10.1) and iron deficiency was 29.4% (95%CI 26.5-32.2). No differences were found when compared with 2006, 24.8% (95%CI 22.3-27.2). Conclusions. The vitamin B12 deficiency is still a problem for women of reproductive age and their offspring in Mexico, while folate deficiency disappeared as a problem. Iron deficiency needs prevention and fortification strategies. © 2015.

Background: 26% of school children in Mexico are overweight or obese (OW/OB), which means a 33% increase in 7 years. Objective: To design, implement and evaluate a strategy to modify the school environment in order to promote healthy lifestyles through physical activity and food habits to prevent OW/OB in children in public schools in Mexico city. Methods: Formative research to diagnose the environment and design the intervention. Evaluation by means of an experimental design in randomly selected intervention and control schools. Results: School environment contributes to energy imbalance, promotes consumption of energy dense foods and beverages and limits the opportunities to practice physical activity. Strategies focused on food habits, physical activity and communication were implemented during two school years in 16 schools. The intervention reduced the offer of energy dense foods, increased the availability of fruits, vegetables and water to drink. Limited changes were observed at individual level, although changes show a trend towards positive effects of the intervention on behaviours and their determinants. Conclusion: The intervention modified the school environment but a more intense and permanent effort is required to change behaviours at individual level. © 2009 SENC.
