In order to improve the quality of life and health of the population in recent years there have been several local social agendas, like Agenda 21 and Healthy Cities.
To identify how social agendas are impacting on the living conditions and health in municipalities of the five regions of Brazil.
Through an ecological longitudinal study, the social agendas' effects on the Social Determinants of Health were measured in 105 municipalities, using indicators related to the eight dimensions of the Millennium Development Goals (MDGs). Indicators were also calculated for other 175 non-exposed municipalities. Descriptive statistics were calculated for each group of municipalities at three different moments: in the year of the agenda implementation, then 3 and 6 years later. The models were adjusted by the method of GEE to assess the effects of the agendas, time and their interaction. Nonparametric analysis of variance was used for the ordinal data with repeated measures.
Impacts of the agendas were detected for reduction of hunger and increase of universal access to education: 'percentage of children under one year with protein/caloric undernourishment' (interaction effect: p = 0.02) and 'Age-grade distortion in the 8th grade of fundamental education' (interaction effect: p < 0.001).
The comparative discussion between model results and descriptive statistics recommends, at further research, extending the period of investigation, using compound indexes, improving the methodology for the apprehension of the impacts of the diffuse social policies for development, as well as using 'mixed methodologies', integrating quantitative and qualitative tools.

Para melhorar a qualidade de vida e a saúde populacionais têm ocorrido nos anos recentes várias agendas sociais locais, como Agenda 21 e Cidades Saudáveis.
Identificar como agendas sociais estão impactando nas condições de vida e de saúde em municípios das cinco regiões do Brasil.
Por um estudo ecológico longitudinal, foram medidos os efeitos das agendas sociais sobre os determinantes sociais de saúde em 105 municípios, usando-se indicadores relacionados às oito dimensões dos Objetivos de Desenvolvimento do Milênio (ODMs). Os indicadores também foram calculados para outros 175 municípios não expostos. Estatística descritiva foi calculada para cada grupo de municípios em três diferentes momentos: ano de implantação da agenda, e 3 e 6 anos mais tarde. Os modelos foram ajustados pelo GEE para avaliar efeito de agenda, de tempo e de interação agenda e tempo. Análise não paramétrica de variança foi usada para dados ordinais com repetição.
Foram encontrados impactos da agenda para a redução da fome e o crescimento do acesso universal à educação: percentagem de crianças menores de um ano desnutridas (interação: p = 0,02) e distorção idade-grau na 8ª série do ensino fundamental (interação: p < 0,001).
análise comparativa entre resultados do modelo e estatística descritiva recomenda, em pesquisa futura: ampliação do período de investigação, uso de índices compostos, aprimoramento de metodologia para apreensão de impactos de políticas sociais difusas voltadas ao desenvolvimento, assim como uso de 'mixed methodologies' que integrem ferramentas quantitativas e qualitativas.

Social agendas, as local or regional efforts directed to social development, are strategies that have been used in Brazil since the early 1990's in two major areas of activity: sustainable environmental development, arising from 1992 Rio Conference regarding the construction of Agenda 2111 .

(Dissertação de Mestrado, 244 p.) . As they were based on specific proposals, the social agendas arose in a way so that they would gradually enlarge their areas of activity, encompassing various sectors of the life of local and regional societies. The scope of their activities took place mainly in the local level.
The Millennium Development Goals (MDGs), a proposal of the United Nations44 . Organización de las Naciones Unidas. Resolución aprobada por la

Brasília, IPEA: Ministério do Planejamento, 2007. to reduce global inequality, pointed out eight groups of activities agreed to by the signatory nations, that consists of a set of improvements to be achieved by the year 2015 on important sectors of life in society. Goals and indicators were proposed for the measurement of the achievements obtained by policies and actions to be undertaken across the world. The eight goals bring challenges regarding the reduction of poverty and hunger, of the inequality between men and women, the improvement in access to basic education, the improvement of the health status of socially and epidemiologically vulnerable groups, environmental development and global integration by means of partnerships for globalization.
The Social Determinants of Health (SDH) constitute a central theme to the development of health, in accordance with a proposal of the General Assembly of the World Health Organization (WHO), which reinforce an indissoluble relationship between the health status of populations and the degree of human development77 . World Health Organization. Bangkok Charter for Health Promotion. WHO: Geneva; 2005. , 88 . CSDH. Closing the gap in a generation: health equity through action on the social determinants of health.

Relatório Final da Comissão Nacional sobre Determinantes Sociais da Saúde. Brasília, Ministério da Saúde, 2008., whose work, guided by research in the quest for scientific evidence, would be to present, based on the results, proposals for integrated actions seeking greater health equity in the country. After two years of work, the Commission obtained important data which confirmed the analysis of the SDH as constituting an important tool for the elucidation of the relationship between health and development. It clearly pointed out the need to overcome the barriers to intersectorial effort in order to improve the health status of populations. It also reaffirm, as in the Dahlgreen/Whitehead model adopted by the National Commission1212 . Dahlgren G, Whitehead M. Policies and Strategies to promote social equity in health. Stockholm: Institute for Future Studies; 1991., that sectorial health actions are only one of the many dimensions of life in society, from which emanate actions directed to social development and health.
Thus, while MDGs presuppose the undertaking of actions in all these dimensions, the proposals of Agenda 21 are very rarely restricted to actions in the traditional environmental sector; and, the Healthy Cities propose actions based on the SDH; all of them in accordance with the premise of multisectoriality.
This paper reports, on the thematic of the SDH, a quantitative methodological approach, as part of a multicenter studya using "mixed methods", as proposed by Creswell et al.1313 . Creswell JW, Plano Clark VL. Designing and conducting Mixed Methods Research. California, EUA, Sage Publications, 2007., relating the effects of social agendas to the change of living conditions and the health status of the populations living in Brazilian municipalities. It also discusses limits and possibilities of the design used to evaluate and monitor the effects of interventions such as social development agendas.
In order to demonstrate the impact of social agendas on MDG selected indicators in Brazilian municipalities, the research was developed in 3 phases.
First, a hundred and five municipalities from the five great regions of the country were
identified as having implemented social agendas (Agenda 21 and Healthy Cities) on the
basis of an extensive survey conducted by Duarte33 . Duarte MF. As agendas sociais brasileiras de desenvolvimento local:
possibilidades de diálogo, articulações e de convergência. São Paulo, Faculdade de
Saúde Pública/USP, 2006. (Dissertação de Mestrado, 244 p.)
and later literature, followed by telephone consultation to municipalities also
indicated by national and regional government agencies such as Departments of Health,
Environment and Cities1414 . Westphal MF (coord.). Relatório Final: Saúde e Desenvolvimento Local:

Paulo, Faculdade de Saúde Pública, CNPq; 2009 (Relatório de Pesquisa). Disponível em:
http://www.cidadessaudaveis.org.br/Det_P... , responsible for the agendas program. The agendas' existence, as indicated previously, was confirmed through inquiries at the official sites of the municipalities involved, and in some cases at sites held by the agendas. Telephone interviews were conducted in all the cities with the managers and some of the participants in order to assess the engagement with the agenda and to gather information on its deployment history, on which departments and institutions had taken part, as well as data about the local key person for its evolution. These were the procedures for confirming the existence of the agenda and registering its year of implementation. The selection of municipalities having agendas was made on the following criteria: agenda being actively applied during the time of the investigation; agenda implemented for at least five years; operation of the agenda begun after 1996; and having a register document about the agenda available for analysis.
In the second phase, an ecological longitudinal study was designed on the basis of the
epidemiological frame of reference1515 . Gordis L. Epidemiologia. 2 ed. Rio de Janeiro: Revinter;
16 . Lilienfeld A. Foundations of epidemiology. New York: Oxford University Press, 1976. - 1717 . Almeida Filho N, Rouquayrol MZ. Elementos de metodologia epidemiológica. In: Rouquayrol MZ, Almeida Filho N. Epidemiologia e Saúde. 6 ed. Rio de Janeiro: Medsi; 2003. to evaluate the association between municipalities with social agendas - Healthy Cities and Agenda 21b - and the MDG targets indicators. Then, a total of 105 municipalities which had taken the initiative of developing social agendas, implementing them effectively (exposed) were matched to a control group of 175 municipalities that did not implement social agendas (not exposed).
As it is considered that there would be differences between pairs of cities with respect to some covariates, a representative sample of municipalities was used as a control group in the study design. The fundamental principle to avoid or minimize such bias was the maximum similarity between the groups, except with regard to the outcome1919 . Rothman KJ, Greenland S. Modern Epidemiology. 2nd ed. Lipponcott-Raven, Philadelphia; 1998.. Therefore, the control (not exposed) municipalities selection criteria should be similar to the studied exposed municipalities, except in regard to the exposure to social agendas and its possible results on MDG indicators, on the basis of the hypothesis that exposure represents health protection and quality of life.
The weighted Euclidean distance was then used to select the municipalities based on two variables: population size and Human Development Index (HDI). This distance was calculated within each federal state, avoiding regional disparity, between all state municipalities-case, and between all municipalities in the same state. The base year for this standardization was 2000.
The measure of variability for pairing was the variations between municipalities: the lesser the distance between a given pair of municipalities - exposed ones and eligible for control - the greater their similarity.
A list of ten municipalities eligible as controls was provided for each of the exposed municipalities, and the regional research teams were instructed to eliminate situations which presented considerable disparity, perhaps not covered by the variables used for pairing, as well as ascertaining that the social agenda had not been fulfilled in these municipalities in the period stipulated.
Two controls were sought for each municipality exposed, though, the absence of a necessary criteria for pairing could mean that some of the exposed municipalities might be paired with only one control, and some of the controls with more than one of the exposed municipalities - yielding samples of different sizes, as between exposed and non-exposed. Then, 280 municipalities were selected for this phase of the study: 105 exposed and 175 controls.
Another important methodological decision was taken as regards the chronological follow-up of the indicators, which was not to be done by what was called "calendar year" - a fixed date or previously agreed year, as from which the municipalities could be compared by virtue of the variations presented by the indicators. The occasion for the beginning of the analysis was defined as the year in which the agenda was implemented, when it would not yet have produced any effects on the indicators. This was denominated time T0. For the control municipalities, the T0 would be that year in which the paired exposed municipality had actually implanted their agenda. As from T0, another two moments were defined: three and six years after the implementation, respectively denominated T3 and T6. That is to say, it was considered - arbitrarily and for methodological purposes only - that the implementation of the social agenda may present some effect after at least three years of activity. It was also determined that when six years had passed since the beginning, a new assessment would be carried out. In leaving aside the 'calendar year', a greater approximation to reality was sought, seeing that the moments T0, T3 and T6 of certain municipalities and their controls would not correspond to the same 'calendar year' of another municipality and its case studies, as the year of the implementation of the agenda will not necessarily be the same in both situations.
Once the exposed municipalities and their respective controls were defined, a set of 29
indicators of the living conditions and health status was collected for all 280
municipalities comprehending the period from 1997 to 2006. An effort was made to build a
table of indicators that could be used in Brazilian follow-up programs to overcome
inequities related to health and conditions of life in municipalities2020 . Westphal MF, Zioni F, Almeida MF, Nascimento PR. Monitoring Millennium
Development Goals in Brazilian municipalities: challenges to be met in facing up to
iniquities. Cad Saúde Pública 2011; 27 Suppl 2: S155-63.. It was elaborated on the basis of the available
data from the National Information Systems. For a detailed description of the
information sources used and the indicators selection process refer to the research

The descriptive statistics - measurements of the central tendency (means) and measurements of variability (Standard Error, SE) are presented in Table 1 for each group of municipalities (with or without agenda) and for each occasion: T0, T3 and T6. The analysis of the descriptive statistics confirmed the maintenance of the database, even in those cases in which discrepant values were identified, as the consultation of the database and the adjustment of the non-parametric models showed that the values would not interfere in the analyses in a way they would affect the statistic inferences.
Descriptive statistics (mean ±standard error) of indicators.
The models were adjusted by the method of Generalized Estimating Equations (GEE)2121 . Paula GA. Modelos de Regressão com apoio computacional. São Paulo: IME-USP; 2004. , 2222 . Hardin J, Hilbe J. Generalized Estimating Equations. London: Chapman and Hall/CRC: 2003. to assess the effects of the agendas, of the independent variable (time) and of the interaction between agenda and time. Nonparametric analysis of variance2323 . Brunner E, Langer F. Nonparametric analysis of ordered categorical data in designs with longitudinal observations and small samples sizes. Biometrical Journal 2000; 42(6): 663-75. was also used for the ordinal data with repeated measures (Two-way NP_ANOVA)2424 . Rosa P. Análise não-paramétrica de dados ordinais com medidas repetidas. (Dissertação de Mestrado), IME-USP, 2001..
For both groups and in the three occasions - T0, T3 and T6 - ,the following hypotheses were tested: a) there is a time effect (difference between the statistics of the indicators over the three moments considered); b) there is an effect resulting from the existence of an agenda (the fact that the municipality's implementation of an agenda is associated with some difference in relation to the group with no agenda); and c) there is an effect of the interaction between time and existence of agenda (the progress over these three moments is different between groups). The significance level was set at 5% for these tests.
Two indicators (1 and 9) had a significant effect of agenda through the years (significant interaction). The percentage of children under the age of one with protein/caloric undernourishment (Indicator 1) was reduced after three years; the effect of interaction (p = 0.02) suggests that another drop occurred in the municipalities with agendas. Three years later, i.e., between T3 and T6, the percentage of undernourishment increased in the group without agenda, whereas a decrease was observed in the group with agenda.
The 'Age-grade distortion in the 8th grade of elementary education' (Indicator 9) presented its greatest drop after three years, even though both groups did not present a significant reduction from T3 to T6.
It is also worth noticing that the percentage of families benefiting from the "Bolsa Família" (Family Grant Program - FGP) (Indicator 3) decreased in the period for both groups of municipalities. Among those with agenda, it departed from a level of 29.9% of beneficiary households at the time of the implementation of the agenda and, six years later, it was 15.8%. Among those with no agenda, it was from 28.2 to 19.9% (interaction effect: 0.096). The FGP is a federal compensatory policy program for the provision of income for families with per capita income below the poverty line. The behavior of the number of families at the time in each municipality expresses the growth or reduction of the percentage of poor individuals.
The coefficient of Tuberculosis prevalence (confirmed cases - Indicator 24), diminished after three years, both in the municipalities and without agendas. The median diminished from 32 to 26% in the municipalities with agendas and from 39% to 35% in the others. Among municipalities, the major alterations have generally occurred in the municipalities with agendas with higher initial rates. However, when the groups are compared in each occasion (at the beginning and three years later), the differences are not significant at the 5% level, but p values are below 10%; so there is evidence, though weak, of lower rates in the municipalities with no social agendas. (Group effect: 0.044)
The percentage of the population served with piped water (Indicator 28) increased after three years, regardless of agendas (Group effect: 0.055; Time effect: 0.02).
Three other indicators only had significant results for time effect. Namely: The percentage of lady town councilors (Indicator 14) presented a significant increase over time regardless of agendas. (Time effect: 0.036). The proportional mortality of children under the age of one (Indicator 17) diminished after six years and dropped significantly between T3 and T6, regardless of agendas. (Time effect: 0.002). As regards the proportion of the coverage of pregnancies with seven or more pre-natal visits (Indicator 21), no differences were found in the values when compared at three-year intervals. From the results of the multiple comparisons, the only difference to be noted was that between T3 and T6, showing that, as from the beginning, there was an increase in the proportion value of the coverage over the six-year period (Time effect: 0.002).
The agendas results would be an improvement in the quality of life of the population in the municipalities where collective actions were implemented to attend to local needs, which is detectable by means of the indicators proposed to measure progress towards the MDGs. Setting up clear indicators to measure progress seems to be in line with Ashton's ideas2525 . Ashton JR. From Healthy Towns 1843 to Healthy Cities 2008. Public Health 2009; 123(1): e11-3. about the need, in the academic field, to 'develop robust methodologies' aimed to deepen and to evaluate the effectiveness of the experiences of Healthy Cities. That is to say, the social forces, which are expressed in local daily life and compose the life of society, beyond (but also including) the health sector, constitute the social process of social production of health and of healthy living conditions. In this study, we sought to measure quantitatively the changes through the MDGs indicators as a methodology to improve the evaluation mechanisms of the agendas.
Regarding the results of descriptive statistics (Table 1), the performances achieved by the municipalities with and without agenda proved to be balanced in relation to the values of the 29 indicators mean variations: in 15 of them, the performance improved in both groups; in 10, it became worse; in 3, the performance improved only for those with no agenda; and, in one of the indicators, we abandoned the descriptive analysis because of a lack of data after three years had passed by (Indicator 12).
The greatest descriptive approximation of the positive performances (15 indicators) demonstrates that in 7 of them, the best performance occurred among those with agenda (indicators 1, 2, 3, 7, 17, 25 and 29); in 6, among those with no agenda (indicators 4, 8, 9, 14, 15 and 21); and in 2, the improvement was equal in both groups (indicators 5 and 20).
In other three indicators (13, 24 and 27) those with no agenda presented a positive performance, while those with agendas presented a negative one.
Considering the indicators for which the performance was negative for both groups of municipalities, it is to be observed that in regard to 4 of the indicators the worsening of the performance was less accentuated among those with an agenda (indicators 6, 19, 22 and 23); with regard to five indicators (10, 11, 16, 26 and 28) the least accentuated worsening occurred among those with no agenda; and there was an equal worsening in both groups as regards indicator 18.
Those with an agenda presented better average values at T0 than those with no agenda with regard to 18 indicators and, on the final occasion (T3 or T6, according to the case) in regard to 15 indicators. Out of 15 situations in which worse values were presented at the end of the period, they had started out (T0) in a worse situation in seven cases (Indicators 14, 18, 22, 23, 24, 26 and 27).
Three observations need to be made at this point: A) it so happens that among 10 indicators concerning those with agendas that had presented worse average values in the beginning, seven of them had no inversion of the situation. Of these, with regard to 4 indicators (Indicators 18, 22, 23 and 26), there was a worsening in both groups; in 2 (Indicators 24 and 27), the worsening occurred only among those with agendas; and, in 1 (Indicator 14), both improved, with better performance than those without agendas. B) Among the 18 indicators, taking into account those with agendas that presented better positions in the initial average values compared to those with no agenda, only in 6 of them (Indicators 4, 8, 16, 19, 20, 21) those with agendas did come to the end of the period with worse values than those with no agenda. And even in those situations, with regard to four of the indicators (4, 8, 20 and 21) both groups presented an improvement in their average values. C) What is verified is that, according to this study, even when the performance over the period does not seem to favor those with agendas, they present better average behavior as to the values of the indicators than those without agenda.
In its turn, the statistical model, when applied to the twenty-nine indicators, did not reveal any significant evidence of the influence of an agenda on the results in the municipalities. Except for the effects of the group or interaction presented by indicators 1, 9, 24 and 28, which in general give only weak evidence of the effect, nothing more substantial expressed any impact of the agendas on living conditions and health status within the local situation.
In three other indicators significant evidence for the effect of time was found, however, without agenda effect: indicators 14, 17 and 21.
Two additional comments should be made regarding the significance of the impacts observed in two indicators. Firstly, the importance of indicator 1 'percentage of children under the age of one with protein / caloric undernourishment', whose performance as a social determinant of health is clearly established in the 'Maternal and Infant Health,' item 6.2.3 of the Report 'The social causes of health inequalities in Brazil,'1111 . CNDSS - Comissão Nacional dos Determinantes Sociais da Saúde. As causas sociais das iniqüidades em saúde no Brasil. Relatório Final da Comissão Nacional sobre Determinantes Sociais da Saúde. Brasília, Ministério da Saúde, 2008. when studies on the nutritional status and poverty are approached. Secondly, to highlight the importance that social agendas may mean in terms of potentiating the effects of FGP (indicator 3), since critical evaluation of the studies on this program, according to CNDSS1111 . CNDSS - Comissão Nacional dos Determinantes Sociais da Saúde. As causas sociais das iniqüidades em saúde no Brasil. Relatório Final da Comissão Nacional sobre Determinantes Sociais da Saúde. Brasília, Ministério da Saúde, 2008. (p. 115), recognizes that it was effectively focused on the poorest, its findings about its impact on child nutrition are not conclusive and that none of the published studies 'has assessed whether there was a reduction of inequalities in nutritional status (or any other indicator) as a result of the program.'
The social agendas were brought together in an assessment research project which made use of the Health Promotion frame of reference, based on the presupposition that local initiatives in social development, as expressed by the agendas, should produce effects on the SDH. Here we adopt the approach of O'Neill and Simard2626 . O'Neill M, Simard P. Choosing indicators to evaluate Healthy Cities projects: a political task? Health Promotion International 2006; 21(2): 145-52. on Healthy Cities, especially concerning the importance of searching for mechanisms to evaluate its effectiveness, and apply it to the models of the discussed agendas. It is relevant to mention the 15th recommendation of "Rio Political Declaration on Social Determinants on Health"2727 . World Health Organization. Rio Political Declaration on Social Determinants of Health. Rio de Janeiro, Brazil, 21 October 2011. Rio de Janeiro, Brazil, WHO; 2011. - "To monitor progress and increase accountability: Acknowledging that monitoring of trends in health inequities and of impacts of actions to tackle them is critical to achieving meaningful progress, that information systems should facilitate the establishment of relationships between health outcomes and social stratification variables and that accountability mechanisms to guide policy-making in all sectors are essential, taking into account different national contexts".
Then, the comparison of the descriptive results with the unconfirmed prior expectation that agendas of local social development, even when acting diffusely, could produce effects in terms of the indicators of living conditions and health status led to questioning as to the time necessary for such maturing as would permit the expected changes to express themselves2525 . Ashton JR. From Healthy Towns 1843 to Healthy Cities 2008. Public Health 2009; 123(1): e11-3.. The specificity which follows from the local reality of each experience, the one that each agenda takes on when promoting development, certainly points at actions directed more to some sectors of local life than others. This would tend to produce more results in some dimensions of social life than in others. The wide spectrum of dimensions of social life covered by the set of indicators would allow changes to be detected wherever they occurred, as their effects in social life sectors. In addition to this, the methodological option made in order to capture any effects resulting of a diffuse set of actions has favored the capture of the degree of deepening the effects achieved and, therefore, of the degree of deepening of the measures taken in each agenda, along with their chronological effectuation: the agendas were taken as a reality that, once started up, tends to spread and deepen, presenting more consistent effects according to the time of its existence.
Another relevant aspect that must be considered is the fact that other results, coming of specific policies that are not connected to the agendas, could be mistakenly taken as results produced by them. Again, the methodological choice has to be one that encompasses the set of municipalities with and without agenda, as well as the wide spectrum of indicators. The ecological and longitudinal character of the epidemiological design adopted favors, in this case, the search for wide spectrum effects resulting from broad policies that stimulate social development and quality of life.
A methodological result of this research project is constituted by the fact that the first occasion of assessment, after three years since the initial implementation of the social development agenda, is a period too short to reveal out modifications in living conditions and health status indicators2020 . Westphal MF, Zioni F, Almeida MF, Nascimento PR. Monitoring Millennium Development Goals in Brazilian municipalities: challenges to be met in facing up to iniquities. Cad Saúde Pública 2011; 27 Suppl 2: S155-63..
The mechanism adopted for chronological comparison (T0, T3, T6) is an innovative tool that was imposed by the project design, which required measurements at moments which varied in accordance with the date of the actual implantation of the agenda. However, as we consider that three years is not enough to permit any quantitative effects on the indicators, the number of municipalities presenting six years of existence drops considerably and, thus, the number of cases for comparison also decreases. Thus, it is as certain that new measurements must be taken as it is imperative the agendas to be maintained and to produce the effects which they propose.
A theme which was not dealt with in this study is that of the discontinuity of the data available for study. Associated with this new fact, it is also worthy of mention that the descriptive statistics show a municipal situation very different from that depicted by the average national or regional results shown by the national or regional averages presented by the recent surveys of the MDGs. The difficulties arising from discontinuous historical series could be partially resolved by recourse to compound indexes.
In brief, we argue that to measure improvements arising from diffuse actions - the social process of construction of agendas - by means of indicators, which by definition express measurements of specific phenomena, demands the use of mixed methods - quantitative and qualitative methodologies as part of the same design - or the use of compound measuring instruments, such as compound indexes, which can combine a set of the dimensions of a social situation - the integrated use of discrete indicators and compound indexes; and a more extensive period of time, greater than the three years tested in our study, so that the changes achieved may in fact be detected by the indicators.
There are several challenges that present such a methodology. The first one consists in the fact it is a study based on secondary data. Although there was a collection of primary data on the existence of Social Agendas in development, through active search in the municipalities, the documentation of these agendas are diverse and information consistency can vary among municipalities. However, a standardized pre-tested instrument was used in an attempt to reduce these heterogeneities. The second challenge relates to the available indicators for measuring the MDGs. In addition to the serious problem of underreporting the main national database on health, the DATASUS, a lot of information are not broken down by municipality, the periodicity of the data is variable and not all indicators are available for all municipalities.
Another issue that seems not to be a limitation, but an inherent characteristic of the study design used, is the difficulty in controls to ensure that municipalities, in fact, controlling for other dimensions that could be related to the outcomes studied (MDGs), beyond the Social Agenda itself. While it is impossible to ensure this control with the same success in the traditional cohort studies (conducted with individuals), the results may indicate that the Social Agenda represents markers of protection for exposed municipalities. The joint analysis of other factors may suggest other dimensions, and features associated with MDGs could be considered in further actions for Health Promotion.
Social agendas, as potential promoters of human development, do not address any specific dimension of social reality; they only produce diffuse effects when they are not directed to a specific sectorial purpose. Two doubts come up: on the one hand, the need for other studies which use both quantitative and qualitative methodologies in a complementary way, thus enhancing the possibility of detecting other effects. On the other hand, the need of making new assessments, after a long period of activity of the agendas. The quantitative measurement of diffuse actions' effectiveness remains to be demonstrated.
