Dyslipidemia and blood lipid levels in patients tratied in primary care centers in east SAN JOSE

Dyslipidemia, i.e. high levels of blood lipids (cholesterol and triglycerides), is strongly related to cardiovascular disease (CVD). In order to reduce the risk of CVD at any moment in a person ́s life, it is crucial to know his/her –and the population’s– lipid profile. The aim of this study was to assess the (statistical) indicators of blood lipids and the prevalence of dyslipidemia in patients treated in the Integral Health Attention Program from Universidad de Costa Rica. A descriptive study was conducted including 10,044 patients aged 20 to 65 years, who were tested for a blood lipid profile in 2006. A total of 2,969 (29.6%) male and 7,075 (70.4%) female patients took part in the study, with an average age of 43.5 years. General averages for blood lipids were: 203.3 mg/dl for total cholesterol, 50.1 mg/dl for HDL, 120.1 mg/dl for LDL, and 165.6 mg/dl for triglycerides. Prevalence of 17.2% was determined for hypercholesterolemia (≥240 mg/dl), as well as 21.3% for low HDL levels (<40 mg/dl), 11.9% for high LDL levels (≥160 mg/dl), and 26.3% for high triglyceride levels (≥200 mg/dl). Women showed higher overall levels of dyslipidemia than men. Based on health areas, no significant differences were found in general lipid levels by age or sex. Results indicate that the general prevalence of dyslipidemia is close to half the rate reported in worldwide literature and lower than results reported in Costa Rican studies. However, general averages exceeded optimal levels for each blood lipid; consequently, it is important to develop health interventions oriented to reduce the impact of dyslipidemia in the studied population.

School-time Extension: Are the School Structure’s Hard Components Modified? Literature Review on the Subject

For more than two decades we have witnessed in Latin America –in Argentina particularly– the development of policies to expand the school day. We understand that the implementation of such policies is an opportunity to observe the behavior of the school’s behavior faced with the attempt to modify one of its hardest components –school-time–; it becomes also a natural laboratory to analyze how much does the traditional organization of school-time can resist, how does it change and how do these changes (if implemented) impact the rest of the school components (spaces, groups, etc.). This paper shows the state of the art of the most significant studies in two research fields, in the context of primary education, on this matter: on the one hand, the studies related to organization and extension of school time and, on the other hand, research on the structural and structuring components of school-related aspects. The literature review indicates that studies on school-time and on the corresponding extension policies and programs do not report the difficulties found when trying to modify the hard components of the school system. Studies with the ‘school system’ as object of study have not approached the numerous school-time extension experiences, although time is one of the structural elements of the system.
