Abstract:

Background: Adolescents who rely on social aid networks tend to be more socially competent and enjoy higher levels of quality of life than those who interact only with their own limited groups of family and friends. In this light, the present study aimed to measure social capital and analyse its possible relation to adolescents’ quality of life. Methods: This is a cross-sectional analytical study with 363 adolescents from the Brazilian NGO. The instruments used included a short Portuguese version of the Integrated Questionnaire to Measure Social Capital (SC-QI) from the World Bank and its abbreviated Portuguese version from the World Health Organization Quality of Life Bref (WHOQoL-Bref) used to measure the quality of life. To measure social capital, the present study chose to use a segmentation analysis, along with the Two-Step Cluster method, applying Euclidian distance and the criteria of centroid aggregation. The Mann-Whitney test was used to compare the scores of WHOQoL-Bref domains among the clusters, at a significance level of 5%. Results: The segmentation analysis resulted in two clusters, with 160 (44.1%) adolescents classified as Low Social Capital (LSC) and 178 (49%) classified as High Social Capital (HSC). Participation in activities for the good of the community (p < 0.001), opinion regarding the differences between people in the community (p = 0.002), and number of community meetings (p < 0.001) constituted the decisive variables for determining the separation of the clusters. When quality of life among the newly formed clusters was compared, the highest average score in the HSC cluster was found in the Psychological Domain (75.4 ± 11.9), whereas in the LSC cluster, the highest average score was found in the Physical Domain (74.6 ± 12.6). Lower quality of life scores was found in the environmental domain for both the LSC clusters (51.3 ± 14.0) and the HSC clusters (54.7 ± 15.5). This difference proved to be statistically significant (p = 0.009). Conclusions: The results showed that adolescents with higher social capital also presented higher

Social capital and self-rated health among adolescents in Brazil: an exploratory study

Abstract: A cross-sectional study was conducted in 2009 among working adolescents supported by a Brazilian NGO. The sample comprised 363 individuals and data were collected using a validated structured questionnaire. The outcome, self-rated health, was measured as a dichotomous variable (poor/good health) and fourteen social capital indicators were investigated (cognitive, behavioral and bonding/bridging). Data were analyzed using multivariate logistic regression. Cognitive (social support and trust), behavioral (civic participation) and bridging social capital were associated with good self-rated health after adjustment of all the other social capital indicators and confounders (sex, age, skin color and educational background).Social capital was associated with self-rated health and the patterns of association differed according its specific dimensions. Cognitive, behavioral and bridging social capitals were protective for adolescents health living in a developing country context..Social capital can be understood as features of social structures - including norms, inter-personal trust, and mutual support - which act as resources for individuals and also facilitate collective action [1,2]. Although the concept originated in sociology to explain diverse phenomena such as educational success, labor market attachment, and the prevention of crime, an increasing number of studies in the last decade and a half have turned to the exploration of social capital in public health [3]. To date, studies have suggested that social capital may be a determinant of health based on its association with mortality [4], health behaviors [5], mental health [6] and self-rated health [7,8].Several mechanisms have been suggested by which social capital can influence health [9]. It is important to note that the influence of social capital on health can be either health-promoting or health-damaging, depending on the social context. Thus, social capital can enhance the diffusion of deleterious health pr

International Journal of Environmental Research and Public Health , 2011, DOI: 10.3390/ijerph8083277
Abstract: The present study assesses the validity and reproducibility of two occlusal indices for epidemiological studies—the Dental Aesthetic Index (DAI) and the Dental Health Component of the Index of Orthodontic Treatment Need (DHC-IOTN) for the identification of orthodontic treatment needs. The total of 131 study models was examined by an examiner (orthodontic specialist) for the determination of the DAI and DHC-IOTN. Thirty days later, further assessment was performed to determine the reproducibility. The duration of each exam was measured in seconds with a stopwatch. The indices were compared by a panel of three experts in orthodontics to evaluate validity. The intra-examiner reliability evaluation resulted in an intraclass correlation coefficient of 0.89 for the DAI (95% CI = 0.64 to 1.0) and 0.87 for the DHC-IOTN (95% CI = 0.56 to 0.96). The time spent on the evaluation of the DHC-IOTN was less than the time spent on that of the DAI (P < 0.001). The accuracy of the indices, as reflected by the area under the receiver-operating characteristic curve, was 61% for the DAI (95% CI = 51 to 70; p = 0.037) and 67% for the DHC-IOTN (95% CI = 58 to 77; p = 0.001). Both indices presented good reproducibility and validity.

International Journal of Environmental Research and Public Health , 2010, DOI: 10.3390/ijerph7030927
Abstract: The aim of the present study was to compare the values of the Thylstrup & Fejerskov Index (TF index) for the determination of the prevalence of dental fluorosis using either all teeth (gold standard) or six upper anterior teeth (simplified TF index). The sample was made up of 396 individuals aged six to 22 years from three Brazilian cities with endemic fluorosis caused by the ingestion of water with high fluoride concentration. The prevalence of dental fluorosis was evaluated by a single trained examiner with excellent intraexaminer agreement (kappa = 0.95). Intraexaminer reproducibilities were calculated at tooth level. Sensitivity, specificity, positive and negative predictive values of the simplified TF compared to gold standard were 90.6 (95%CI: 86.6 to 93.6), 100 (95%CI: 95.3 to 100), 100 (95%CI: 98.3 to 100) and 77.5 (95%CI: 69.8 to 83.5), respectively. The ROC value was 0.953 (95%CI: 0.933 to 0.973). The simplified TF index proved suitable for determining the prevalence of dental fluorosis in regions with endemic fluorosis caused by the ingestion of water with high concentrations of fluoride.

International Journal of Environmental Research and Public Health , 2010, DOI: 10.3390/ijerph7083115
Abstract: The present paper examines the relationship between hydrochemical characteristics and endemic dental fluorosis, controlling for variables with information on an individual level. An epidemiological survey was carried out in seven rural communities in two municipalities in the state of Minas Gerais, Brazil. The Thystrup & Fejerskov index was employed by a single examiner for the diagnosis of dental fluorosis. A sampling campaign of deep groundwater in the rural communities of interest was carried out concomitantly to the epidemiological survey for the determination of physiochemical parameters. Multilevel modeling of 276 individuals from seven rural communities was achieved using the non-linear logit link function. Parameters were estimated using the restricted maximum likelihood method. Analysis was carried out considering two response variables: presence (TF 1 to 9) or absence (TF = 0) of any degree of dental fluorosis; and presence (TF ≥ 5—with loss of enamel structure) or absence of severe dental fluorosis (TF ≤ 4—with no loss of enamel structure). Hydrogeological analyses revealed that dental fluorosis is influenced by the concentration of fluoride (OR = 2.59 CI95% 1.07–6.27; p = 0.073) and bicarbonate (OR = 1.02 CI95% 1.01–1.03; p = 0.060) in the water of deep wells. No other variable was associated with this prevalence (p > 0.05). More severe dental fluorosis (TF ≥ 5) was only associated with age group (p < 0.05). No other variable was associated to the severe dental fluorosis (p > 0.05). Dental fluorosis was found to be highly prevalent and severe. A chemical element besides fluoride was found to be associated (p > 0.05) to the prevalence of dental fluorosis, although this last finding should be interpreted with caution due to its p value.

Fernandes, Elaine Toledo Pitanga;Ferreira, Efigênia Ferreira e;
Brazilian Oral Research , 2004, DOI: 10.1590/S1806-83242004000300013
Abstract: considering that the variations on clinical judgment with respect to replacement of restorations are a problem which affects dentistry, the aim of this study was to elaborate, implement and evaluate a programme of participative training to standardize criteria for the evaluation of amalgam restorations. five professors of integrated clinic of the school of dentistry of the university of vale do rio doce (univale), brazil, visually and radiographically evaluated 28 extracted permanent teeth presenting amalgam restorations. the research was developed in four distinct phases: first - the teeth were evaluated according to individual criteria to determine whether restorations should be replaced or not; second - the examiners participated in a training programme with the objective of standardizing the evaluation criteria; third - soon after the training, the teeth were re-evaluated using the adopted standardized criteria; fourth - five months after the training, the procedures on third phase were repeated. for each restoration the examiners registered the main reason for considering the restoration: satisfactory, requiring total substitution, requiring partial substitution or requiring finishing/polishing. after participating in the training programme the examiners presented a statistically significant reduction (sign test: z = 0.4989, p = 0.0022) in indicating the need to substitute restorations, result which was maintained five months after training. this programme of participative training can be organized and implemented to standardize the criteria to evaluate amalgam restorations achieving satisfactory results with an impact on clinical practice.

Abstract: the aim of this study was to identify the knowledge users of a teaching clinic have regarding basic rights related to the possibilities of dental care. a structured interview was conducted with 56 users (proportion estimate). upon entering the healthcare service, users are far from what could be described as aware citizens. they obtain care through friendship (32.1%) or cases of urgency (28.6%). when they do not obtain care, the most mentioned alternative is a private clinic (42.8%), which indicates that the constitutional right to healthcare is not incorporated by the population of the present study, as they attempt to solve their problems individually and with their own resources. this line of thinking remains (50%) even in cases of urgency (pain), as only four individuals reported they would seek care in the public sector. this underlines the lack of knowledge of the basic right to healthcare and other alternatives that the organized public clinic offers. the characterization that a service of this nature performs favors is confirmed, as 76.8% of the interviewees reported not knowing who finances their treatment and 42.8% would not file complaints despite being dissatisfied with the service. in spite of the explanatory work carried out by the institution, users still do not have information about their rights and citizenship, a factor that prevents political participation. the interviewed community does not display the characteristics of a group that is aware of their rights regarding dental care.
