Objective: to analyze the Family Health Strategy (FHS) coverage time trend in Brazil, its Regions and Federative Units (FUs) in 2006-2016., Methods: this was an ecological study with time series analysis of Ministry of Health Primary Care Department data; Prais-Winsten regression was used., Results: FHS coverage in Brazil in 2006 and 2016 was 45.3% and 64.0%, respectively, with an increasing trend of coverage (annual variation = 8.4%: 95%CI 7.4;9.3); all five regions showed an increasing trend in coverage, as did the majority of FUs, with the exception of Roraima, Amapá, Piauí, Rio Grande do Norte and Paraíba, which showed stability; in 2016, 14 FUs had coverage of between 75 and 100%, and 11 had coverage of between 50 and 74,9%; coverage in São Paulo and Federal District was below 50%., Conclusion: although, overall, FHS coverage increased, 13 FUs presented coverages below 75% in 2016; therefore, more efforts are needed to universalize coverage.

Objective: to analyze the association between counseling by health care professionals and healthy behaviors among the elderly., Methods: population-based, cross-sectional study with elderly individuals (≥60 years) interviewed in 2014; Poisson regression was used to estimate crude and adjusted prevalence ratios (PR) of associations between counseling by health professionals on the reduction of salt, sugar and fat and on the practice of physical activity during the year previous to the interview and healthy behaviors., Results: 1,281 elderly individuals were interviewed; after adjustments, the elderly who mentioned receiving counseling by health professionals reported reduction in the intake of salt (PR 1.64; 95%CI 1.41;1.91), sugar and sweets (PR 1.21; 95%CI 1.08;1.36) and greater practice of physical activity (PR 1.21; 95%CI 1.06;1.39), when compared to the elderly who had not received any counseling., Conclusion: the counseling carried out by health professionals seems to favor the practice of healthy habits among elderly individuals.

Objective: to analyze the simultaneity of two groups of risk behaviors for sexually transmitted infections in Brazilian adolescents., Methods: cross-sectional study with data from the National Adolescent School-based Health Survey 2012; the outcomes were (1) simultaneous consumption of alcohol, tobacco and drugs (at least two), and (2) no use of condom and having two or more sexual partners., Results: simultaneity of consumption of alcohol, tobacco and drugs was present in 14.7% of the boys and 21.5% of the girls, and was more prevalent among white individuals, with more educated mothers, and who did not live with their parents; approximately 12.0% of the adolescents presented simultaneity of no use of condom and having two or more sexual partners; this was more common among younger boys, not white (PR=1.22; 95%CI 1.10;1.36), and who did not live with their parents (PR=1.78; 95%CI 1.48;2.16), whilst among girls, this outcome was associated with higher age., Conclusion: both outcomes were associated with different characteristics, depending on the sex of the adolescent.

Objective: to analyze the time trend on the demand and lack of access to public health services in Brazil., Methods: this is a panel of cross-sectional studies with data of the National Household Sample Survey (1998, 2003, 2008) and the National Health Survey (2013); the prevalence of demand and lack of access within the fifteen days prior to the survey was estimated; Poisson regression was used for trend analysis., Results: the demand for health services increased from 13.0% (95%CI 12.3;13.7), in 1998, to 15.0% (95%CI 14.5;15.4), in 2013; the lack of access remained stable, being of 3.7% (95%CI 3.2;4.2) in 1998 and 4.5% (95%CI 4.0;5.0) in 2013., Conclusions: the increase in demand for health services and the stability in the lack of access indicate improvements in the Brazilian public health system performance; additional efforts are required to ensure universal access to public health services in Brazil.

Objective: to analyze dengue incidence trend in Brazil from 2002 to 2012., Methods: this was an ecological study with data of the Information System for Notifiable Diseases (Sinan); the incidence rate was calculated by age groups, states and macroregions, through Prais-Winsten regression., Results: dengue incidence rates in Brazil, in 2002 and 2012, were of 401.6 and 301.5 per 100,000 inhabitants, respectively; annual increment rates were stable (21.4%; 95%CI -19.8;83.7) in most of the states, except for Alagoas (38.9%; 95%CI 5.1;83.5) and Tocantins (50.4%; 95%CI 12.6;100.7); the North Region was the only region to present increase trend in the incidence of dengue., Conclusion: although rates have remained stable in most of the states, they are still high in Brazil; broader public policies focusing on new dengue control strategies are necessary.
