Prevalence of trachoma in indigenous and non-indigenous areas, Northeastern Brazil, 2019-2021

Objective

To estimate the prevalence of trachoma in indigenous and non-indigenous populations in selected areas of the state of Maranhão, in northeastern Brazil.

Methods

This was a population-based survey with probabilistic sampling. For the diagnosis of trachoma, external ocular examination was performed using head magnifying loupes, at 2.5X magnification. The prevalence of trachomatous inflammation - follicular (TF) in children aged 1-9 years and the prevalence of trachomatous trichiasis (TT) in the population aged ≥15 years were estimated. Relative frequencies of sociodemographic and environmental characteristics were obtained.

Results

The study included 7 971 individuals, 3 429 from non-indigenous populations and 4 542 from indigenous populations. The prevalence of TF in non-indigenous and indigenous populations was 0.1% and 2.9%, respectively, and the prevalence of TT among indigenous populations was 0.1%.

Conclusions

The prevalence of TF and TT in the two evaluation units in the state of Maranhão were within the limits recommended for the elimination of trachoma as a public health problem. However, the prevalence of TF was higher in the indigenous evaluation unit, indicating a greater vulnerability of this population to the disease. The prevalence of TF of below 5.0% implies a reduction in transmission, which may have resulted from improved socioeconomic conditions and/or the implementation of the World Health Organization SAFE strategy.

Population Prevalence of Trachoma in Nine Rural Non-Indigenous Evaluation Units of Brazil

PURPOSE

To assess the contemporary prevalence of trachoma in Brazil's non-indigenous population, surveys of those thought to be at greatest risk of disease were conducted.

METHODS

Rural census tracts of non-indigenous population from nine mesoregions were selected to compose the survey evaluation units (EUs) by considering previously endemic municipalities at greatest risk of trachoma. In each of the nine EUs, we conducted a population-based prevalence survey. Every resident of selected households aged ≥ 1 year was examined for trachomatous inflammation - follicular (TF) and trachomatous trichiasis (TT). Additionally, data were collected on household-level access to water, sanitation, hygiene (WASH) and education.

RESULTS

A total of 27,962 individuals were examined across nine EUs. The age-adjusted TF prevalence in 1-9-year-olds was <5% in each EU. The age- and gender-adjusted prevalence of TT unknown to the health system in ≥15-year-olds was <0.2% in eight EUs; in one EU, it was 0.22%. The median number of households surveyed per EU with access to an improved drinking water source within a 30-minute roundtrip of the house was 66%. School attendance was >99% of surveyed children.

CONCLUSIONS

The prevalence of TF was well below the target for elimination as a public health problem in all EUs. Because EUs surveyed were selected to represent the highest-risk non-indigenous areas of the country, TF prevalence is unlikely to be ≥5% in non-indigenous populations elsewhere. In one EU, the prevalence of TT was above the target threshold for elimination. Further investigation and possibly improvement in TT surgical provision are required in that EU.

Factors associated with worsening in the self-rated health status of Brazilian women who lived with dependent elderly people during the first wave of COVID-19

The objective is to analyze the factors associated with the worsening of the self-rated health (SRH) of Brazilian women who live with elderly people with functional dependence (EFD) during the first wave of COVID-19. ConVid - Behavior Research was used as a data source. For the analysis, the group of women who lived with EFD was compared with those who lived with the elderly without any dependence. Hierarchical prevalence ratio (PR) models were estimated to test the associations between sociodemographic characteristics, changes in income, routine activities and health in the pandemic, with the outcome of worsening SRH. This worsening was more frequent in the group of women living with EFD. After adjusting for hierarchical factors, being black (PR=0.76; 95%CI 0.60-0.96) and having a per capita income lower than minimum wage (PR=0.78; 95%CI 0.64- 0.96) were shown to be protective factors for SRH worsening among EFD co-residents. Indisposition, emergence/worsening of back problems, affected sleep, poor SRH, feeling loneliness and difficulty in carrying out routine activities during the pandemic were positively associated factors. The study demonstrates that living with EFD was associated with a worsening in the health status of Brazilian women during the pandemic, especially among those of higher social status.

Factors associated with the incidence and worsening of back pain during the first wave of COVID-19 in Brazil

Abstract The article aims to estimate the incidence and worsening of back pain (BP) during the first wave of COVID-19 in Brazil, as well as to investigate demographic, socioeconomic factors and associated changes in living conditions. ConVid - Behavior Research, applied between April and May 2020, was used as data source. The number and distribution of respondents who developed BP and those who had a worsening of the preexisting problem, their 95% confidence intervals and Pearson’s Chi-square test were estimated. The odds ratio of developing BP or worsening a preexisting problem was also estimated using multiple logistic regression models. Pre-existing BP was reported by 33.9% (95%CI 32.5-35.3) of respondents and more than half (54.4%; 95%CI 51.9-56.9) had worsened. The cumulative incidence of BP in the first wave of the pandemic was 40.9% (95%CI 39.2-42.7). Being a woman, the perceived increase in housework and the frequent feeling of sadness or depression were associated with both outcomes. Socioeconomic factors were not associated with any of outcome. The high incidence and worsening of BP during the first wave reveal the need for studies in more recent periods, given the long duration of the pandemic.

Use of psychotropic drugs by population in an area affected by the tailings dam rupture: Brumadinho Health Project

OBJECTIVE

To describe the consumption of psychotropic drugs in the adult population residing in Brumadinho, Minas Gerais, after the Vale dam collapse, which occurred in 2019.

METHODS

This is a cross-sectional study, part of the Brumadinho Health Project, developed in 2021, with a representative population-based sample of adults (18 years and over) residing in Brumadinho. A total of 2,805 adults with information on self-reported use of psychotropic drugs (antidepressants and anxiolytics-hypnotics/sedatives) in the last 15 days were included in the analysis. The prevalence of psychotropic drug use was estimated, and the most used psychotropic drugs were identified. Pearson's chi-square test (with Rao-Scott correction) was used to test associations between exposures and use of psychotropic drugs, considering a significance level of p<0.05.

RESULTS

The use of antidepressants (14.2%) was more common than the use of anxiolytics or hypnotics/sedatives (5.2%), with sertraline and fluoxetine being the most used antidepressants. The use of anxiolytics and hypnotics/sedatives was higher among residents who lived in the area directly affected by the dam's mud, and the use of any psychotropic drug was higher among those who lost a relative/friend in the disaster and assessed that their health worsened after the disaster, and among women.

CONCLUSION

The results of the study corroborate what was observed in other populations exposed to similar tragedies, regarding the pattern of associations and the of use of psychotropic drugs.

Use of health services and adherence to social distancing by adults with Noncommunicable Diseases during the COVID-19 pandemic, Brazil, 2020

The present study investigates the association between the self-reported diagnosis of noncommunicable disease (NCD) and the adherence to social distancing and the use of health services during the COVID-19 pandemic. This was a cross-sectional study with Brazilian adults who participated in the ConVid- Behavior Survey, conducted online between April 24 and May 24, 2020(n = 45.161). This studyconsidered the following NCDs: diabetes, hypertension, respiratory disease, heart disease, and cancer, and evaluated the use of health services and the adherence to social distancing, as well as estimated the prevalences and adjusted prevalence ratio (aPR); 33,9% (95% CI: 32,5-35,3) referred to one or more NCD. Individuals with NCDsshowed a greater adherence to intense social distancing (aPR: 1,07;95% CI: 1,03-1,11), sought out health services more often (aPR:1,24; 95% CI:1,11-1,38), and found greater difficultyin scheduling doctor's appointments (aPR:1.52; 95% CI 1,35-1,71), receiving healthcare treatment (APR:1,50;95% CI:1,22-1,84) and medication (APR:2,17;95% CI:1,77-2,67), and performing examinations (APR:1,78;95% CI:1,50-2,10) and scheduled interventions (APR:1,65;95% CI:1,16-2,34). The presence of NCDs was associated with social distancing, seeking out health care, and difficulty in using health services.

Cross-validation of four different survey methods used to estimate illicit cigarette consumption in Brazil

Objective

To cross-validate estimates of the size of the illicit cigarette trade based on the results of four different survey methods.

Methods

In 2018/2019, four non-industry-funded, large-scale studies were conducted in selected Brazilian cities: packs discarded in household garbage/PDG (1 city), packs littered in the streets/PLS (5 cities), a phone survey of tobacco users’ purchase behaviors/VIGITEL (5 cities), and a face-to-face household survey of tobacco users’ purchase behaviors/FTF-household (2 cities). The proportions of illicit cigarettes consumed were based on the price paid by smokers in their last purchase (VIGITEL or FTF-household) and/or direct observation of brand names and health warnings (PDG, PLS or FTF-household).

Results

Based on PLS, the share of packs that avoided taxation ranged from 30.4% (95% CI 25.6% to 35.7%) in Rio de Janeiro to 70.1% (95% CI 64.6% to 75.0%) in Campo Grande; and PDG conducted in Rio de Janeiro found an even lower proportion point estimate of illicit cigarette use (26.8%, 95% CI 25.1% to 28.6%). In FTF-household, the share of illicit cigarette consumption based on the self-reported price ranged from 29.1% (95% CI 22.4% to 35.7%) in Rio de Janeiro to 37.5% (95% CI 31.2% to 43.7%) in São Paulo, while estimates based on pack observation ranged from 29.9% (95% CI 23.3% to 36.5%) in Rio de Janeiro to 40.7% (95% CI 34.3% to 47.0%) in São Paulo. For all cities, VIGITEL presented the lowest levels of illicit consumption, and most illicit brands were produced in Paraguay.

Conclusions

Small differences in the estimated levels of illicit trade across methods were found, except for the phone survey. The cross-validation of estimates from independent studies is important to help effectively implement tobacco excise tax policy in Brazil and other low-income and middle-income countries.

Primary care and healthcare utilization among older Brazilians (ELSI-Brazil)

OBJECTIVE

To characterize healthcare access and utilization among older Brazilians.

METHODS

Data are from the baseline wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), which is a nationally representative, population-based cohort study of persons aged 50 years and older conducted in 2015/2016 (n = 9,412). The prevalence of barriers to primary care and number and type of doctor visits in the past 12 months are compared by three main sources of healthcare (private, Family Health Strategy, traditional public clinics). Two-part multivariable hurdle analyses assess the relation between healthcare utilization, primary care problems, and source of healthcare, while controlling for healthcare determinants.

RESULTS

Females comprised 54% of the sample, with a mean age of 63 years. There were no demographic differences by source of healthcare. Nearly 83% had at least one doctor visit in the past 12 months, with higher use among private health plan holders. Private health plan holders most frequently visited specialists, while those using the public system were more likely to visit a general practitioner. Primary care barriers averaged 3.5 out of 12 and were the highest among those using traditional health posts. A greater number of primary care problems was negatively associated with all types of healthcare utilization.

CONCLUSIONS

By international standards, access to basic healthcare among older Brazilians is relatively high. Nevertheless, different levels of primary care problems between the public and private sectors and resulting utilization patterns suggest the need to continue working to close remaining gaps.

Aspects of social participation and neighborhood perception: ELSI-Brazil

OBJECTIVE

To determine the impact of the physical and social surroundings of the neighborhood, which are presented as facilitators or barriers for the social participation of Brazilian older adults.

METHODS

The study was conducted in a probabilistic representative sample of the Brazilian population aged 50 years and older and who lived in urban areas (n = 7,935). The response variable was social participation, which was defined from two questions about activities performed with other persons: visited friends or relatives in their homes in the last 12 months (yes, no); went out with other persons to public places, such as restaurant, movies, club, park, in the last 12 months (yes, no). The explanatory variables included fear of falling because of defects in sidewalks, concern about the difficulty to get on a bus, subway, or train, difficulty to cross streets, and perception of violence in the neighborhood. Potential confounding variables included age, marital status, education level, self-rated health, living in an asphalted or paved street, time living in the municipality, and socioeconomic position score. Prevalence ratios and respective confidence intervals were estimated using Poisson regression.

RESULT

Difficulty to cross streets presented an independent association with restricted social participation (PR = 0.95; 95%CI 0.93-0.98) among both women (PR = 0.96; 95%CI 0.92-0.99) and men (PR = 0.94; 95%CI 0.90-0.99). Concern about the difficulty to get on a bus, subway, or train was associated with the outcome only among men (PR = 0.95; 95%CI 0.91-0.99). The fear of falling because of defects in sidewalks and the perception of violence in the neighborhood were not associated with social participation.

CONCLUSIONS

Urban characteristics that hinder the crossing of streets and accessibility to public transport can be inferred as important barriers for the social participation of Brazilian older adults.

Life course socioeconomic inequalities and oral health status in later life: ELSI-Brazil

OBJECTIVE

To investigate the association between life course socioeconomic conditions and two oral health outcomes (edentulism and use of dental prostheses among individuals with severe tooth loss) among older Brazilian adults.

METHODS

This was a cross-sectional study with data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) which includes information on persons aged 50 years or older residing in 70 municipalities across the five great Brazilian regions. Regression models using life history information were used to investigate the relation between childhood (parental education) and adulthood (own education and wealth) socioeconomic circumstances and edentulism and use of dental prostheses. Slope index of inequality and relative index of inequality for edentulism and use of dental prostheses assessed socioeconomic inequalities in both outcomes.

RESULTS

Approximately 28.8% of the individuals were edentulous and among those with severe tooth loss 80% used dental prostheses. Significant absolute and relative inequalities were found for edentulism and use of dental prostheses. The magnitude of edentulism was higher among individuals with lower levels of socioeconomic position during childhood, irrespective of their current socioeconomic position. Absolute and relative inequalities related to the use of dental prostheses were not related to childhood socioeconomic position.

CONCLUSIONS

These findings substantiate the association between life course socioeconomic circumstances and oral health in older adulthood, although use of dental prostheses was not related to childhood socioeconomic position. The study also highlights the long-lasting relation between childhood socioeconomic inequalities and oral health through the life course.

Life course and work ability among older adults: ELSI-Brazil

OBJECTIVE

To examine factors associated with perception of work ability in a nationally representative sample of Brazilians aged 50 years and over.

METHODS

We used data from 8,903 participants of the baseline survey of the Brazilian Longitudinal Study of Aging (ELSI-Brazil). The dependent variable was self-rated work ability (good or very good versus fair, poor, or very poor). Independent variables included factors that operate at the beginning, middle, and current stage of life. Multivariate analysis was based on prevalence ratios (PR) and 95% confidence intervals (95%CI) estimated by Poisson regression.

RESULTS

Good work ability was reported by 49% of \ participants (49.4% among men and 48.6% among women). Results of the multivariate analysis showed that, for both men and women, good work ability showed positive and statistically significant associations (p < 0.05) with good health up to 15 years of age (PR = 1.22 and 1.18 , respectively), educational level ≥ 8 years (PR = 1.19 and 1.21, respectively), and current good self-rated health (PR = 1.88 and 1.94, respectively). Negative associations were observed for current age (PR = 0.99 for each increase of one year among men and women), medical diagnosis of depression (PR = 0.70 for men and PR = 0.87 for women), and having one or more at least chronic diseases (PR = 0.88 for men and 0.91 for women). Only for men, positive associations for the age at which they started working (PR = 1.14 and 1.12 for 11–17 and ≥ 18 years, respectively) and living with a spouse (PR = 1.09) were found.

CONCLUSIONS

Work ability in older ages is built over the life course, particularly by the health conditions in childhood and adolescence, age at which men begin working, educational level, and health conditions in older ages. Policies aimed at increasing longevity in the labor market must take these factors into account.

Multimorbidity: The Brazilian Longitudinal Study of Aging (ELSI-Brazil)

OBJECTIVE

To evaluate the occurrence and factors associated with multimorbidity among Brazilians aged 50 years and over.

METHODS

This is a cross-sectional study in a nation-based cohort of the non-institutionalized population in Brazil. Data were collected between 2015 and 2016. Multimorbidity was assessed from a list of 19 morbidities, which were categorized into ≥ 2 and ≥ 3 diseases. The analysis included the calculation of frequencies and the most frequent 10 pairs and triplets of combinations of diseases. The crude and adjusted analyses evaluated the demographic, socioeconomic, behavioral, and contextual variables (area of residence, geopolitical region, and coverage of the Family Health Strategy) using Poisson regression.

RESULTS

From the total of 9,412 individuals, 67.8% (95%CI 65.6–69.9) and 47.1% (95%CI 44.8–49.4) showed ≥ 2 and ≥ 3 diseases, respectively. In the adjusted analysis, women, older persons, and those who did not consume alcohol had increased multimorbidity. There were no associations with race, area of residence, geopolitical region, and coverage of the Family Health Strategy. The 10 pairs (frequencies observed between 11.6% and 23.2%) and the 10 triplets (frequencies observed between 4.9% and 9.5%) of the most frequent diseases mostly included back problems (15 times) and systemic arterial hypertension (11 times). All combinations were statistically higher than expected by chance.

CONCLUSIONS

The occurrence of multimorbidity was high even among younger individuals (50 to 59 years). Approximately two in three (≥ 2 diseases) and one in two (≥ 3 diseases) individuals aged 50 years and over presented multimorbidity, which represents 26 and 18 million persons in Brazil, respectively. We observed high frequencies of combinations of morbidities.

Falls among Brazilian older adults living in urban areas: ELSI-Brazil

OBJECTIVE

To assess the prevalence and factors associated with falls in a nationally representative sample of older Brazilians residing in urban areas.

METHODS

Data from 4,174 participants (60 years or older) from the baseline of ELSI-Brazil, conducted between 2015 and 2016, were used. The outcome variable was the reporting of one or more falls in the last 12 months. The exploratory variables were sociodemographic characteristics, factors related to the urban environment, and health conditions. Statistical analysis was performed using Poisson regression.

RESULTS

The prevalence of falls was 25.1%. Of these, 1.8% resulted in a hip or femur fracture and, among them, 31.8% required surgery for prosthesis placement. Statistically significant associations (p < 0.05) with falls were observed for females [prevalence ratio (PR) = 1.26], age group of 75 years or older (PR = 1.21), fear of falling due to defective sidewalks (PR = 1.47), fear of crossing streets (PR = 1.22), diabetes (PR = 1.17), arthritis or rheumatism (PR = 1.29), and depression (PR = 1.53). No significant associations were found for educational level, marital status, hypertension, and perception of violence in the neighborhood.

CONCLUSIONS

The factors associated with falls among older adults are multidimensional, comprising individual characteristics and the urban environment, which indicates the need for intra and intersectoral actions to prevent falls in this population.

Factors associated with the receipt of pensions among older adults: ELSI-Brazil

OBJECTIVE

To describe the prevalence of receipt of pensions and associated factors in a nationally representative sample of the Brazilian population aged 50 years and over.

METHODS

We used data from 9,130 participants from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) baseline survey. The outcome variable was receipt of pensions from any source. The exploratory variables were age, gender, residence by region and by urban/rural area, household arrangements, schooling, household assets, perception of income sufficiency, age when started working, number of chronic diseases, and functional limitation. The analyses were based on the Poisson and binary logistic regressions.

RESULTS

The prevalence of the receipt of pension was 54.3%. In the multivariate analysis, the following factors showed statistically significant (p < 0.05) associations with the outcome: age [Prevalence Ratio (PR) = 2.59 and 3.24 for 60-69 and 70 years], rural residence (PR = 1.23 ), residence in the Northeast, South and Southeast compared to the North (PR ranging from 1.18 to 1.23), living arrangements (PR = 1.07 and 1.15 for living with one person and living alone), perception of income sufficiency (PR = 1.08 and 1.15 for sometimes and always), functional limitation (PR = 1.13) and having 1 and ≥ 2 chronic diseases (PR = 1,09 and 1,17). Negative association was observed for 5-8 years of education. No association between age when the individual started working and the outcome was observed. Younger participants (50-59 years old) with ≥ 2 diseases or functional limitation were 31% and 63% more likely to receive pensions, respectively; the strength of these associations declined with age.

CONCLUSIONS

The results suggest that health conditions are important determinants of early retirement. Discussions to increase age to the retirement cannot be separated from those on improvements in the health conditions of the Brazilian population.

Hospitalizations among older adults: results from ELSI-Brazil

OBJECTIVE

To examine the factors associated with hospital use and their frequency in a nationally representative sample of the Brazilian population aged 50 years or older.

METHODS

Data from the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), conducted in 2015-2016, were used. Predisposing, enabling and need factors for the use of health services were considered. The analyzes were based on the Hurdle regression model and on estimates of population attributable risks.

RESULTS

Among 9,389 participants, 10.2% had been hospitalized in the previous 12 months. After adjusting for potential confounding variables, statistically significant associations (p < 0.05) were observed for need factors (previous medical diagnosis for chronic diseases and limitation to perform basic activities of daily living) and for enabling factors (living in a rural area and in the North and Midwest regions of the country). The analysis of population attributable risks (PAR) showed a hierarchy of the need factors for the occurrence of hospitalizations, with higher contributions by stroke (PAR = 10.7%) and cardiovascular disease (PAR = 10.0%), followed by cancer (PAR = 8.9%), difficulty to perform basic activities of daily living (PAR = 6.8%), depression (PAR = 5.5%), diabetes (PAR = 4.4% ) and hypertension (PAR = 2.2%).

CONCLUSIONS

Four of the major diseases associated with hospitalizations (stroke, cardiovascular disease, diabetes and hypertension) are part of the Brazilian list of primary care-sensitive hospitalizations. These results show that there is a window of opportunity to reduce unnecessary hospitalizations among older Brazilian adults through effective primary care actions.

Frailty profile in Brazilian older adults: ELSI-Brazil

OBJECTIVE

To estimate the prevalence of frailty and to evaluate the associated factors in the non-institutionalized Brazilian population aged 50 years or older.

METHODS

The analyses were conducted in 8,556 participants of the baseline survey of the Longitudinal Study of Health of the Brazilian Elderly (ELSI-Brazil) conducted in 2015 and 2016. Frailty was defined based on five characteristics: weight loss, weakness, slowness, exhaustion and low level of physical activity. Participants with three or more characteristics were classified as frail. A Poisson regression model was used to examine the association between frailty and sociodemographic and health factors.

RESULTS

The prevalence of frailty was 9.0% (95%CI 8.0-10.1) among participants aged 50 years or over. Among the older adults aged 60 or over, the prevalence was 13.5% (95%CI 11.9-15.3) and 16.2% (95%CI 14.3-18.3) among those 65 aged years or over. Factors associated with higher prevalence of frailty were low schooling, residence without a partner, health conditions (poor self-rated health and two or more chronic diseases) and limitation to perform basic activities of daily living.

CONCLUSIONS

The prevalence of frailty among Brazilians aged 65 years or older is similar to their European counterparts. Poor health conditions, functional limitation and low schooling emerge as the factors most strongly associated with the frailty in this population.

Inequalities in basic activities of daily living among older adults: ELSI-Brazil, 2015

OBJECTIVE

To evaluate the magnitude of wealth-related inequalities in basic activities of daily living among community-dwelling Brazilian older adults and to determine the contribution of demographic, socioeconomic, and health conditions to the inequality.

METHODS

We used data from the 2015 Brazilian Longitudinal Study of Aging (ELSI-Brazil) with a nationally representative sample of adults aged 50 years or older. We assessed wealth-related inequalities in basic activities of daily living by the concentration index. Concentration index was decomposed to determine the contribution of demographic, health, and socioeconomic factors to wealth-related inequalities in basic activities of daily living.

RESULTS

The prevalence of disability in the sample was 15.7% (95%CI 14.9–17.6). The concentration index was -0.145 (95%CI -0.194– -0.097), which indicates that disability is concentrated in the poorest individuals in Brazil. Inequalities in basic activities of daily living disability are primarily explained by socioeconomic status (wealth and own education) not by demographic or health factors.

CONCLUSIONS

There are avoidable wealth-related inequities for those with a disability in Brazil. The strong contribution of the socioeconomic status highlights the need for new public health policies that promote equity, universality, and integrality, in addition to the expansion of home nursing public services.

Cost-related underuse of medications in older adults: ELSI-Brazil

OBJECTIVE

To assess the prevalence and factors associated with cost-related underuse of medications in a nationally representative sample of Brazilians aged 50 years and over.

METHODS

Among the 9,412 participants of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), 6,014 reported using at least one medication on regular basis and were included in the analysis. Underuse of medications was by stopping taking or reducing the number of tablets or the dose of any prescribed medication for financial reasons. The theoretical framework used for the selection of the exploratory variables included predisposing factors, enabling factors, and factors of need. Associations were tested by Poisson regression.

RESULTS

The prevalence of underuse of medications was 10.6%. After adjustments for relevant covariables, positive and statistically significant associations (p < 0.05) with the outcome were found for females [prevalence ratio (PR) = 1.39], sufficiency of the family income for expenses (PR = 1.74 for sometimes and PR 2.42 for never), frequency with which the physician explains about the disease and treatment (PR = 1.31 for rarely or never), number of medications used (PR = 1.39 for 2-4 and 1.53 for 5 or more), fair (PR = 2.02) and poor or very poor self-rated health (PR = 2.92), and a previous medical diagnosis of depression (PR = 1.69). Negative associations were observed for the age groups of 60-79 years (PR = 0.75) and 80 years and over (PR = 0.43), socioeconomic status of the household (PR = 0.70, 0.79, and 0.60 for the second, third, and fourth quartile, respectively), and private health plan coverage (PR = 0.79). There were no associations between hypertension and self-reported diabetes and underuse of medications.

CONCLUSIONS

Cost-related underuse of medications is multidimensional and complex, and it covers socio-demographic characteristics, health conditions, and the use of health services. The explanation about the disease and its treatment to the patient and the expansion of the universal access to pharmaceutical care can minimize the risks of underuse.

Prevalence of chronic non-communicable diseases and association with self-rated health: National Health Survey, 2013

OBJECTIVE

To analyze the profile of 10 chronic noncommunicable diseases investigated in the National Health Survey carried out in Brazil in 2013 and their association with the self-rated health.

METHODS

A cross-sectional, population-based nationwide study with 60,202 individuals aged 18 years old or more. Sampling process by conglomerate was carried out in three stages of selection: census tract, household, and individual. The prevalence of chronic diseases by age, gender and educational status and the confidence intervals of 95% , the mean age at the first diagnosis and the proportion of limitation of the usual activities were calculated. To test the association with self-rated health, the logistic regression procedure adjusted for gender and age was used.

RESULTS

The more prevalent diseases were hypertension (21.4%), depression (7.6%), arthritis (6.4%), and diabetes mellitus (6.2%). Individuals diagnosed with stroke reported greater limitations in the daily activities (38.6%). There was a gradient in the prevalence by age and educational level, and all the diseases were more frequent among women. A worse self-rated health was observed among those with a diagnosis of stroke (OR = 3.60; p < 0.001) and those who referred two diseases (OR = 5.53; p < 0.001) or three or more diseases (OR = 10.86; p < 0.001).

CONCLUSIONS

Because these diseases are associated with modifiable risk factors, the prevention with population focus is the best strategy to reduce the burden of these diseases.

Inequities in Healthcare utilization: results of the Brazilian National Health Survey, 2013

BACKGROUND

The Brazilian Unified Health System is a public healthcare system that has universal and equitable access among its main principles, but the continental size of the country and the complexity of the public health system complicate the task of providing equal access to all. We aim to investigate the factors associated with inequities in healthcare utilization in Brazil.

METHODS

We employed data from a nationally representative cross-sectional study (2013 National Health Survey; n = 60,202). The outcome was underutilization of healthcare by adults, defined as lack of utilization of one or more of these services: physician or dentist consultation, and blood glucose or blood pressure screening. A logistic regression model, considering the complex sample, was employed (alpha = 5 %).

RESULTS

0.7 % of the sample never visited a physician, 3.3 % never visited a dentist, 3 % never underwent blood pressure screening, 11.5 % never underwent blood glucose screening, and 15 % never utilized at least one of these services. Multivariate models showed a higher likelihood of underutilization of healthcare among individuals of the lowest social class "E" (AOR = 6.31, 95 % CI = 3.76-10.61), younger adults (Adjusted Odds Ratio, or AOR = 4.40, 95 % CI = 3.78-5.12), those with no formal education or incomplete primary education (AOR = 2.93, 95 % CI = 2.30-3.74), males (AOR = 2.16, 95 % CI = 1.99-2.35), and those without private health insurance (AOR = 2.11, 95 % CI = 1.83-2.44). Individuals self-classified as "white" were less likely to report underutilization (AOR = 0.82, 95 % CI = 0.75-0.90).

CONCLUSIONS

Despite recent expansion of primary healthcare and oral health programs in Brazil, we observed gaps in healthcare utilization among the most vulnerable segments of the population.

Mortality from Alzheimer's disease in Brazil, 2000-2009

Alzheimer's disease is the most prevalent type of dementia in the elderly worldwide. To evaluate the mortality trend from Alzheimer's disease in Brazil, a descriptive study was conducted with the Mortality Information System of the Brazilian Ministry of Health (2000-2009). Age and sex-standardized mortality rates were calculated in Brazil's state capitals, showing the percentage variation by exponential regression adjustment. The state capitals as a whole showed an annual growth in mortality rates in the 60 to 79 year age bracket of 8.4% in women and 7.7% in men. In the 80 and older age group, the increase was 15.5% in women and 14% in men. Meanwhile, the all-cause mortality rate declined in both elderly men and women. The increase in mortality from Alzheimer's disease occurred in the context of chronic diseases as a proxy for increasing prevalence of the disease in the population. The authors suggest healthcare strategies for individuals with chronic non-communicable diseases.

[Correcting vital information: estimating infant mortality, Brazil, 2000-2009]

OBJECTIVE

To propose a simplified method of correcting vital information and estimating the coefficient of infant mortality in Brazil.

METHODS

Vital data in the information systems on mortality and live births were corrected using correction factors, estimated based on events not reported to the Brazilian Ministry of Health and obtained by active search. This simplified method for correcting vital information for the period 2000-2009 for Brazil and its federal units establishes the level of adequacy of information on deaths and live births by calculating the overall coefficient of mortality standardized by age and the ratio between reported and expected live births, respectively, in each Brazilian municipality. By applying correction factors to the number of deaths and live births reported in each county, the vital statistics were corrected, making it possible to estimate the coefficient of infant mortality.

RESULTS

The highest correction factors were related to infant deaths, reaching values higher than 7 for municipalities with very precarious mortality information. For deaths and live births, the correction factors exhibit a decreasing gradient as indicators of adequacy of the vital information improve. For the year 2008, the vital information corrected by the simplified method per state were similar to those obtained in the research of active search. Both the birth rate and the infant mortality rate decreased in the period in all Brazilian regions. In the Northeast, the annual rate of decline was 6.0%, the highest in Brazil (4.7%).

CONCLUSIONS

The active search of deaths and births allowed correction factors to be calculated by level of adequacy of mortality information and live births. The simplified method proposed here allowed vital information to be corrected per state for the period 2000-2009 and the progress of the coefficient of infant mortality in Brazil, its regions and states to be assessed.

Estimação da razão de mortalidade materna no Brasil, 2008-2011

Neste trabalho, propõe-se uma metodologia de estimação da razão de mortalidade materna (RMM), no Brasil, 2008-2011, por meio das informações do Ministério da Saúde. O método proposto leva em consideração, o sub-registro geral de óbitos, as proporções de investigação de mortes de mulheres em idade fértil, bem como as proporções de óbitos maternos que foram atribuídos, indevidamente, a outras causas antes da investigação. A RMM foi estimada por Unidade de Federação no triênio de 2009-2011. No Brasil, a RMM atinge o valor mínimo em 2011 (60,8/100 mil nascidos vivo) e o máximo em 2009 (73,1/100 mil nascidos vivos), explicado, provavelmente, pela epidemia de influenza A (H1N1). Os maiores valores da RMM foram encontrados no Maranhão e no Piauí, ultrapassando 100/100 mil nascidos vivos, e o menor foi apresentado por Santa Catarina, o único estado com magnitude inferior a 40/100 mil nascidos vivos. Os resultados indicaram valores superiores aos que deveriam ter sido alcançados de acordo com a quinta meta do milênio, mas apontaram para um decréscimo significativo no período de 1990-2011, se as estimativas anteriores da RMM forem consideradas.

Desenho da amostra Nascer no Brasil: Pesquisa Nacional sobre Parto e Nascimento

Este artigo descreve a amostra da Pesquisa Nacional sobre Parto e Nascimento no Brasil. Os hospitais com 500 ou mais nascidos vivos em 2007 foram estratificados por macrorregião, capital de estado ou não, e tipo, e selecionados com probabilidade proporcional ao número de nascidos-vivos em 2007. Amostragem inversa foi usada para selecionar tantos dias de pesquisa (mínimo de 7) quantos fossem necessários para alcançar 90 entrevistas realizadas com puérperas no hospital. As puérperas foram amostradas com igual probabilidade entre as elegíveis que entraram no hospital no dia. Os pesos amostrais básicos são o inverso do produto das probabilidades de inclusão em cada estágio e foram calibrados para assegurar que estimativas dos totais de nascidos vivos dos estratos correspondessem aos totais de nascidos vivos obtidos no SINASC. Para os dois seguimentos telefônicos (6 e 12 meses depois), a probabilidade de resposta das puérperas foi modelada pelas variáveis disponíveis na pesquisa de base, a fim de corrigir, para a não resposta, os pesos amostrais em cada onda de seguimento.

Prevalence and factors associated with nutritional deviations in women in the pre-pregnancy phase in two municipalities of the State of Rio de Janeiro, Brazil

OBJECTIVE: To assess the prevalence and potential factors associated with pre-pregnancy nutritional status of women. METHODS: This is a cross-sectional study carried out between December 2007 and November 2008 with 1,535 women in the first trimester of pregnancy and randomly selected in health units of the Brazilian public health system (SUS) in the municipalities of Queimados and Petrópolis in the State of Rio de Janeiro. The diagnosis of nutritional deviations was based on the Body Mass Index, according to the classification of the Institute of Medicine, and the following categories were obtained: underweight, normal weight, overweight and obesity. In the statistical analysis, the multinomial logistic regression model was used and an odds ratio and confidence interval of 95% were estimated. RESULTS: The sample included women between 13 and 45 years. The prevalence of underweight, overweight and obesity were 10, 18 and 11%, respectively. Women living in Queimados, adolescents, women who did not live with a partner and smokers had a higher proportion of low pre-pregnancy weight. There was an association between hypertension, overweight and obesity. Adolescents presented lower chance to overweight and obesity. Living in Queimados reduced the odds of overweight. CONCLUSION: The proportion of pre-pregnancy nutritional deviations was high, and recognizing factors that lead to them is very important for an early identification of women at nutritional risk, with view to interventions to reduce the adverse effects of malnutrition on maternal and child health.

Self-rated health by HIV-infected individuals undergoing antiretroviral therapy in Brazil

In 2008, a survey was applied to a probabilistically selected sample of 1,245 HIV-infected patients on antiretroviral therapy in Brazil. In this work, the analysis was focused on self-rated health. The analysis was conducted according to sex, age, socioeconomic variables, and clinical and treatment-related patient characteristics. Through stepwise logistic regression procedures, the main predictors of good perception of health status were established. Results showed that 65% self-rated health state as good or excellent, 81% do have no or slight difficulty in following treatment, but 34% men and 47% women reported intense or extreme degree of anxiety/worry feelings. Educational level, work situation, presence of side effects and AIDS-related symptoms were the main predictors of good self-perception of health. Problems related to animus status, involving worry and anxiety about the future are still barriers that must be overcome to improve quality of life of people living with HIV/AIDS.

[Measurements of reported morbidity and interrelationships with health dimensions]

OBJECTIVE

To assess the interrelationships between self-rated health, perceptions of long-term illness and diagnoses of chronic diseases.

METHODS

In the World Health Survey, carried out in Brazil in 2003, 5,000 individuals aged 18 years and over who had been selected from a three-stage stratified sample were interviewed. The original questionnaire was adapted for the Brazilian context. It covered the presence of long-term illness or disability, self-rating of health (general and in several domains) and diagnoses of six chronic diseases (arthritis, angina, asthma, depression, schizophrenia and diabetes mellitus). To compare the relationships between self-rated health, perceptions of long-term illness and the chronic diseases evaluated, the statistical test of homogeneity of proportions and multiple logistic regression models were used.

RESULTS

Self-rating of health as "not good" and perceptions of having long-term illnesses were significantly more frequent among women, individuals aged 50 years and over and individuals with one or more of the diseases investigated. The interviewees with a diagnosis of diabetes mellitus presented the worst self-rated health: 70.9% reported having a long-term illness and 79.3% considered that their health was "not good". Worse health ratings were found when two or more diseases were present together. The effect of self-rating of health on the perceptions of long-term illness was stronger than was the number of diseases.

CONCLUSIONS

The three ways of measuring morbidity presented significant interrelationships. Self-rating of health as "not good" had a more important effect on the perceptions of long-term illness, thus suggesting that subjective measurements of health status may be more sensitive for establishing and monitoring individuals' wellbeing.
