It integrates the series commissioned by the International Epidemiological Association to all WHO Regions to identify global opportunities to promote the development of epidemiology.</p><p><bold>Methods</bold> Health situations of the regions were analysed based on published data on selected mortality, morbidity and risk factors. Epidemiological publication output by country was estimated by Medline bibliometrics. Internet and literature searches and data provided by key informants were used to describe perspectives on epidemiological training, research and funding.</p><p><bold>Findings</bold> Despite important advances in recent decades, LAC remains the world's most unequal region. In 2010, 10% of the LAC's people still lived in conditions of multidimensional poverty, with huge variation among countries. The region has experienced fast and complex epidemiological changes in past decades, combining increasing rates of non-communicable diseases and injuries, and keeping uncontrolled many existing endemic and emerging diseases. Overall, epidemiological publications per year increased from 160 articles between 1961 and 1970 to 2492 between 2001 and 2010. The increase in papers per million inhabitants in the past three decades varied from 57% in Panama to 1339% in Paraguay. Universities are the main epidemiological training providers. There are at least 34 universities and other institutions in the region that offer postgraduate programmes at the master’s and doctoral levels in epidemiology or public health. Most LAC countries rely largely on external funding and donors to initiate and sustain long-term research efforts. Despite the limited resources, the critical mass of LAC researchers has produced significant scientific contributions.</p><p><bold>Future needs</bold> The health research panorama of the region shows enormous regional discrepancies, but great prospects. Improving research and human resources capacity in the region will require establishing research partnerships within and outside the region, between rich and poor countries, promoting collaborations between LAC research institutions and universities to boost postgraduate programmes and aligning research investments and outputs with the current burden of disease.</p></div></front><back><div1

It integrates the series commissioned by the International Epidemiological Association to all WHO Regions to identify global opportunities to promote the development of epidemiology.</p><p><bold>Methods</bold> Health situations of the regions were analysed based on published data on selected mortality, morbidity and risk factors. Epidemiological publication output by country was estimated by Medline bibliometrics. Internet and literature searches and data provided by key informants were used to describe perspectives on epidemiological training, research and funding.</p><p><bold>Findings</bold> Despite important advances in recent decades, LAC remains the world's most unequal region. In 2010, 10% of the LAC's people still lived in conditions of multidimensional poverty, with huge variation among countries. The region has experienced fast and complex epidemiological changes in past decades, combining increasing rates of non-communicable diseases and injuries, and keeping uncontrolled many existing endemic and emerging diseases. Overall, epidemiological publications per year increased from 160 articles between 1961 and 1970 to 2492 between 2001 and 2010. The increase in papers per million inhabitants in the past three decades varied from 57% in Panama to 1339% in Paraguay. Universities are the main epidemiological training providers. There are at least 34 universities and other institutions in the region that offer postgraduate programmes at the master’s and doctoral levels in epidemiology or public health. Most LAC countries rely largely on external funding and donors to initiate and sustain long-term research efforts. Despite the limited resources, the critical mass of LAC researchers has produced significant scientific contributions.</p><p><bold>Future needs</bold> The health research panorama of the region shows enormous regional discrepancies, but great prospects. Improving research and human resources capacity in the region will require establishing research partnerships within and outside the region, between rich and poor countries, promoting collaborations between LAC research institutions and universities to boost postgraduate programmes and aligning research investments and outputs with the current burden of disease.</p></abstract><kwd-group><kwd>Epidemiology</kwd><kwd>Latin America and Caribbean</kwd><kwd>health status</kwd><kwd>health inequality</kwd><kwd>global health</kwd></kwd-group><counts><page-count count="15"></page-count></counts></article-meta></front><body><sec><title>Region characteristics and main health problems</title><p>This article integrates the series commissioned by the International Epidemiological Association to address the current situation of epidemiology in all of the World Health Organization (WHO) Regions.

Eight out of the 24 countries in the Caribbean had less than 100 000 inhabitants in 2009. Brazil is the largest country, both in territory and population, with ∼191 million inhabitants in 2010. Mexico is the second largest country, with a 110 million inhabitants. The Federation of Saint Kitts and Nevis is the smallest country in territory and population, with less than 50 thousand inhabitants.</p><p>The LAC population more than tripled between 1950 and 2010, going from ∼167 million to 588 million inhabitants, constituting ∼8.5% of the world population. The United Nations Organization estimates that the population in the region will reach 730 million in 2050. Most of its population (81%) now live in urban areas (<xref ref-type="table" rid="dys017-T1">Table 1</xref>). LAC is the developing region with the smallest proportional population growth expected by mid-century, largely due to the fertility declines in several of its largest countries. The regional total fertility rate was about 2.3 in 2010 with a contraceptive prevalence rate of 67%, rivalling that of developed countries.<xref ref-type="bibr" rid="dys017-B1"><sup>1</sup></xref><table-wrap id="dys017-T1" position="float"><label>Table 1</label><caption><p>Selected World Development indicators for Latin America and Caribbean Region (LAC), 1960–2008</p></caption><table frame="hsides" rules="groups"><thead align="left"><tr><th rowspan="1" colspan="1">Indicator</th><th rowspan="1" colspan="1">1960</th><th rowspan="1" colspan="1">1970</th><th rowspan="1" colspan="1">1980</th><th rowspan="1" colspan="1">1990</th><th rowspan="1" colspan="1">2000</th><th rowspan="1" colspan="1">2008</th></tr></thead><tbody align="left"><tr><td rowspan="1" colspan="1">Total population</td><td rowspan="1" colspan="1">218 045 567</td><td rowspan="1" colspan="1">284 417 924</td><td rowspan="1" colspan="1">360 583 923</td><td rowspan="1" colspan="1">441 272 661</td><td rowspan="1" colspan="1">518 543 254</td><td rowspan="1" colspan="1">572 556 071</td></tr><tr><td rowspan="1" colspan="1">GDP per capita (current US$)</td><td rowspan="1" colspan="1"> 372</td><td rowspan="1" colspan="1"> 614</td><td rowspan="1" colspan="1"> 2134</td><td rowspan="1" colspan="1"> 2631</td><td rowspan="1" colspan="1"> 4125</td><td rowspan="1" colspan="1"> 7623</td></tr><tr><td rowspan="1" colspan="1">Urban population (% of total)</td><td rowspan="1" colspan="1">48.9</td><td rowspan="1" colspan="1">57.0</td><td rowspan="1" colspan="1">64.9</td><td rowspan="1" colspan="1">70.6</td><td rowspan="1" colspan="1">75.3</td><td rowspan="1" colspan="1">78.6</td></tr><tr><td rowspan="1" colspan="1">Fertility rate, total (births per woman)</td><td rowspan="1" colspan="1">6.0</td><td rowspan="1" colspan="1">5.3</td><td rowspan="1" colspan="1">4.2</td><td rowspan="1" colspan="1">3.2</td><td rowspan="1" colspan="1">2.7</td><td rowspan="1" colspan="1">2.2</td></tr><tr><td rowspan="1" colspan="1">Death rate, crude (per 1000 people)</td><td rowspan="1" colspan="1">13.0</td><td rowspan="1" colspan="1">10.4</td><td rowspan="1" colspan="1">8.3</td><td rowspan="1" colspan="1">6.8</td><td rowspan="1" colspan="1">6.0</td><td rowspan="1" colspan="1">6.0</td></tr><tr><td rowspan="1" colspan="1">Life expectancy at birth, female (years)</td><td rowspan="1" colspan="1">58.2</td><td rowspan="1" colspan="1">62.5</td><td rowspan="1" colspan="1">67.4</td><td rowspan="1" colspan="1">71.6</td><td rowspan="1" colspan="1">75.0</td><td rowspan="1" colspan="1">76.6</td></tr><tr><td rowspan="1" colspan="1">Life expectancy at birth, male (years)</td><td rowspan="1" colspan="1">54.3</td><td rowspan="1" colspan="1">58.1</td><td rowspan="1" colspan="1">61.7</td><td rowspan="1" colspan="1">65.1</td><td rowspan="1" colspan="1">68.4</td><td rowspan="1" colspan="1">70.3</td></tr><tr><td rowspan="1" colspan="1">Age dependency ratio (% of working-age population)</td><td rowspan="1" colspan="1">86.6</td><td rowspan="1" colspan="1">88.0</td><td rowspan="1" colspan="1">79.1</td><td rowspan="1" colspan="1">70.2</td><td rowspan="1" colspan="1">60.6</td><td rowspan="1" colspan="1">54.6</td></tr><tr><td rowspan="1" colspan="1">Mortality rate, infant (per 1000 live births)</td><td rowspan="1" colspan="1">103.4</td><td rowspan="1" colspan="1">85.7</td><td rowspan="1" colspan="1">63.1</td><td rowspan="1" colspan="1">41.8</td><td rowspan="1" colspan="1">27.6</td><td rowspan="1" colspan="1">19.7</td></tr><tr><td rowspan="1" colspan="1">Mortality rate, under 5 years (per 1000)</td><td rowspan="1" colspan="1">154.6</td><td rowspan="1" colspan="1">121.7</td><td rowspan="1" colspan="1">83.1</td><td rowspan="1" colspan="1">52.4</td><td rowspan="1" colspan="1">33.5</td><td rowspan="1" colspan="1">23.5</td></tr></tbody></table><table-wrap-foot><fn id="dys017-TF1"><p><italic>Source</italic>: World Bank, World Development Indicators, 2008.</p></fn></table-wrap-foot></table-wrap></p><p>More than 400 different indigenous groups are estimated to live within the region, ∼10% of the total population.

Still in this sub-region, it is estimated that 1.6% of women and 0.7% of men between 15 and 24 years of age are infected with HIV, rates lower only than those found in sub-Saharan Africa.<xref ref-type="bibr" rid="dys017-B39"><sup>39</sup></xref></p><p>Along with Africa and Asia, the LAC region is also affected by neglected infectious diseases (NIDs). The NIDs, a diverse group of more than 20 CDs, are clearly related to poverty, especially for those living in the poorest rural areas and in deprived urban or peri-urban communities with unsafe water, poor sanitation and the proliferation of rodent animal reservoirs and vectors.<xref ref-type="bibr" rid="dys017-B40"><sup>40</sup></xref> Based on their prevalence and healthy life-years lost from disability, hookworm infection, other soil-transmitted helminth infections and Chagas disease are the most important NIDs in the region.<xref ref-type="bibr" rid="dys017-B41"><sup>41</sup></xref> The total burden of these NIDs in LAC may exceed the disease burdens from malaria or tuberculosis, and according to some estimates, it exceeds that of HIV/AIDS.<xref ref-type="bibr" rid="dys017-B16"><sup>16</sup></xref></p></sec></sec></sec><sec><title>Health systems</title><p>The national health care systems of countries in the LAC region are very diverse in terms of their organizational structure or institutional configuration and the principles guiding the public and private sectors roles in the provision (financing and/or delivery) of health care services.<xref ref-type="bibr" rid="dys017-B42"><sup>42</sup></xref> The national health systems range from predominantly public, as in Cuba, Jamaica and Mexico, to a wide variety of mixed systems, as in Brazil, Ecuador and Peru. In all countries, private expenditures, including direct out-of-pocket expenditures and voluntary contributions to privately managed prepaid health plans and health insurance schemes are the largest component of national health care expenditures, ranging from 66% in Brazil to ∼50% in Ecuador, Jamaica and Peru.<xref ref-type="bibr" rid="dys017-B43"><sup>43</sup></xref> Although per capita health expenditure on health (combined public and private expenditures) has increased between 2000 and 2005 in all country-income groups, they fall far short of the expenditure levels in high-income countries.<xref ref-type="bibr" rid="dys017-B19"><sup>19</sup></xref></p><p>Overall, access to health care services has improved dramatically in LAC since the 1950s, both in terms of the number and share of the population who can get treated for their health problems and the range and effectiveness of health services for treating them. The Unified Health System, created in Brazil in 1989, is a comprehensive tax-based universal health system that provides free health care at primary, secondary and tertiary levels.<xref ref-type="bibr" rid="dys017-B44"><sup>44</sup></xref> However, in the region as a whole, inequity in health care utilization is still great. In Bolivia, for example, 97.9% of the people in the highest income quintile have access to health care services, but in the lowest quintile only 19.8% have access. In Peru, 96.7% of the highest income quintiles have access, compared with 14.3% in the lowest. And in Guatemala, the figures are 91.5% and 9.3%, respectively.<xref ref-type="bibr" rid="dys017-B17"><sup>17</sup></xref> In some countries, some new strategies to finance health expenditure have been developed, specifically in Mexico, a governmental strategy called ‘Seguro Popular’ now covers over 45 million persons avoiding out of pocket expenditure and providing health services with more than 250 health interventions.<xref ref-type="bibr" rid="dys017-B45"><sup>45</sup></xref></p></sec><sec><title>Millennium development health goals</title><p>According to the UNDP, the LAC region as a whole has already reached or is able to reach five out of the eight millennium development health goal (MDG) targets by 2015.

A poor correlation between the main causes of disease burden and the research conducted in the LAC can also be seen by examining results of published randomized controlled trials in Latin America, as NCD and injuries are seldom addressed.<xref ref-type="bibr" rid="dys017-B52"><sup>52</sup></xref></p><p>In contrast to the observed distribution of total DALYs by major groups of causes in LAC countries in the year 2000, as estimated by the Global Burden of Disease Study,<xref ref-type="bibr" rid="dys017-B11"><sup>11</sup></xref> the percentage of published articles in the past decade shows an over-representation of CDs, maternal and perinatal and nutritional deficiencies (49% of the published material vs 27% of total DALYs in 2000), whereas NCDs and injuries are under scored (43% vs 55% and 7% vs 18% of DALYs, respectively) (<xref ref-type="fig" rid="dys017-F3">Figure 3</xref>).

We obtained information from 16 countries (Argentina, Barbados, Bolivia, Brazil, Colombia, Cuba, Dominican Republic, Grenada, Haiti, Jamaica, Mexico, Peru, Puerto Rico, St Kitts and Nevis, Suriname and Trinidad and Tobago) about epidemiological training, funding for research projects, presence of epidemiological societies and conferences held in epidemiology. Although there are many ongoing initiatives related to hands-on epidemiology training, most of them linked to outbreak response,<xref ref-type="bibr" rid="dys017-B65"><sup>65</sup></xref> the focus of the survey was on training at the postgraduate level.</p><p>In almost all countries, universities are the main epidemiological training providers. There are at least 34 universities and others institutions in the region that offer postgraduate programmes at the master’s and doctoral levels, either in epidemiology or in public health with a concentration in epidemiology. In total, key respondents reported the existence, between master’s and doctorates, of at least 119 Programmes. According to them, epidemiological training through a Master in Public Health is the most common finding. Brazil is the country that leads in numbers of master’s and doctorate programmes (50) followed by Mexico (32). In the same vein, Brazil also has more doctorate programs (21) than the sum of all other countries (10). Among the Caribbean countries, Cuba and Jamaica are the most advantaged with a total of 11 programmes.</p><p>Examples of between-countries collaboration are the postgraduate programmes in Clinical Epidemiology and Evidence Based Health, which are offered in Chile, Colombia, Argentina and Peru (Latin American Clinical Epidemiology network).

In contrast, private institutions were not identified as a source of financial support for research projects.</p><p>With regards to the existence of an established organization that congregates epidemiologists, it is not possible to draw conclusions for Caribbean countries because of the limited information collected. For the other countries, several organizations were mentioned, including ABRASCO—Associação Brasileira de Saúde Coletiva (Brazil), ASOCEPI—Asociación Colombiana de Epidemiología (Colombia), La Asociación de Salud Pública de Haití (Haiti), Sociedad Mexicana de Salud Pública (Mexico) and Sociedad Peruana de Epidemiología (Peru). However, for Argentina and Bolivia no specific epidemiological association was reported.

Whereas Brazil, Cuba and other few countries have well established local support for science, as demonstrated by the scope of training provided, the majority of LAC countries rely largely on external funding and donors to initiate and sustain long-term research efforts.<xref ref-type="bibr" rid="dys017-B58"><sup>58</sup></xref><sup>,</sup><xref ref-type="bibr" rid="dys017-B65"><sup>65</sup></xref><sup>,</sup><xref ref-type="bibr" rid="dys017-B68"><sup>68</sup></xref></p><p>Behind the financial factor, and equally important, is the human capacity factor. The diaspora of scientists from LAC to developed countries has always been present—and difficult to measure. Nevertheless, well-established research teams can be identified in the region in several areas relevant to epidemiology.<xref ref-type="bibr" rid="dys017-B69"><sup>69</sup></xref> One of the traditional patterns that keep such sustained development has been the maintenance of links between people returning from a period of training abroad with their counterparts. Today, with the ease of communications, such networking links have become broader, both in geographical outreach and breadth of collaborative research fields. One example of networking is the Latin American Studies Consortium in Obesity (LASO).<xref ref-type="bibr" rid="dys017-B70"><sup>70</sup></xref></p><p>As most research support comes from international funding agencies, in the recent decades funding from major scientific funding bodies has promoted the establishment of centres of excellence in the region, aiming to strengthen research activities together with a training and capacity-building component.

It also has two important advantages in relation to other WHO Regions: similar cultural identity and a common language for most of the population. Furthermore, it has the SCIELO—Scientific Electronic Library Online, created in 1997, a pioneering initiative which offers open access to selected scientific journals in three languages: Portuguese, English and Spanish. Due to its policy and equity strategy, it granted visibility to scientific production from Latin America and the Caribbean.</p><p>Important advances in regional agreements and policies to develop countries’ health research agendas and strengthen their capacities are starting following the first Latin American Conference on Research and Innovation for Health<xref ref-type="bibr" rid="dys017-B75"><sup>7</sup><sup>5</sup></xref> held in Brazil, in 2008.<xref ref-type="bibr" rid="dys017-B76"><sup>76</sup></xref> For instance, Paraguay is working towards a formal health research system; El Salvador has included a section on health research in its national health policy; Guatemala has established a coordinating office for health research within the Ministry of Health; and Uruguay has announced the launch of a sectoral fund for health research. Other countries are implementing strategies that strengthen coordination and communication, and are sharing and learning from each other's experience.<xref ref-type="bibr" rid="dys017-B77"><sup>77</sup></xref></p><p>MERCOSUR, an economic block created in 1991 by Argentina, Brazil, Paraguay and Uruguay to eliminate tariffs and commercial restrictions on their products (Bolivia, Chile, Colombia Ecuador, Peru and Venezuela are associate members) began supporting S&T collaboration.
