Factors associated with the use of dental services in the previous 12 and 36 months by Brazilian older people residing in rural areas.

OBJECTIVES: To describe the use of dental services in two periods and associated factors in older people residing in the rural area of a municipality in southern Brazil. METHODS: This was a cross-sectional study nested in a cohort study. A standardised questionnaire was used to collect the variables of interest. The dependent variables were the use of dental services in the 12 and 36 months prior to the interview. RESULTS: A total of 863 older people were interviewed, 24.7% of whom had visited a dentist in the previous year and 38.7% had visited a dentist in the previous 3 years. Skin colour, health insurance and self-rated health were associated with both outcomes. Individuals with non-white skin, those who did not have health insurance and those who considered their health to be poor or very poor were more likely to take a long time before seeking oral health services. Differences between the two outcomes were observed in oral health and the use of tobacco. The likelihood of having gone more than 3 years without visiting a dentist was greater among smokers and lower among those with dental caries. CONCLUSIONS: The prevalence of dental service use was low. Variables related to the adoption of unhealthy behaviours and the occurrence of oral diseases were only related to the use of dental services 36 months prior to the interview. Public policies must be reorganised to prioritise population groups with greater difficulties in the use of dental services.

The Role of Physical Vulnerability in the Association Between Social Activities and Cognitive Performance in Rural Older Adults: A Longitudinal Study.

The aim of this study was to examine the association of social activities with cognitive performance in older adults in the southern area of Brazil, considering the important moderating role of physical vulnerability. A prospective population-based study was conducted in the rural area of Rio Grande, Rio Grande do Sul, Brazil. Self-reported social activities were collected at baseline. Cognitive performance and physical vulnerability were measured in the second wave of data collection. The association of social activities with cognitive performance was determined using robust generalized linear models. In adjusted analysis, the social activities were positively associated with cognitive performance in physically vulnerable older adults. However, this association was not found in those who were nonvulnerable. Our findings may contribute to future investigations of possible explanatory avenues for the association between social activities and cognitive performance as well as the development of interventions aimed at improving cognitive skills.

Vulnerability among rural older adults in southern Brazil: population-based study.

INTRODUCTION: The study aimed to estimate the prevalence of vulnerability, and to identify the associated factors of vulnerability among rural community-dwelling older adults living in the municipality of Rio Grande, Rio Grande do Sul, Brazil. METHODS: This was a cross-sectional, population-based study of a sample of individuals aged 60 years or older. Data from the first follow-up of the EpiRural Cohort Study (2018-2019) were used. Vulnerability was assessed using the Vulnerable Elders Survey (VES-13). The maximum score is 10 and older adults with scores of 3 or more are classified as vulnerable. Poisson regression with robust adjustment of variance was used for crude and adjusted analyses. For the analysis of the associated factors, a theoretical model was constructed with three hierarchical levels. The variables were adjusted in relation to each other within each level; those with a significance level of 0.20 or less were included in the regression model and adjusted to a higher level, with a subsequent level of significance of 5%. RESULTS: The overall prevalence of vulnerability was 40.8% (95%CI 37.5-44.3). Vulnerability was more prevalent among women (PR=1.45; 95%CI 1.23-1.71), older adults who did not work (PR=1.70; 95%CI 1.17-2.45), those who lived without a partner (PR=1.26; 95%CI 1.07-1.47), those with diabetes (PR=1.23; 95%CI 1.03-1.48), those with depression (PR=1.21; 95%CI 1.02-1.42), those with osteoporosis (PR=1.38; 95%CI 1.15-1.66), and those with sarcopenia (PR=1.67; 95%CI 1.38-2.02). CONCLUSION: Vulnerability is common among rural community-dwelling older adults and is associated with sociodemographic and health characteristics.

Aging in a rural area in southern Brazil: designing a prospective cohort study.

INTRODUCTION: This article presents the methods used to design a prospective cohort study with older adults from a rural area in the far south of Brazil (EpiRural Cohort Study), as well as to describe the cohort profile. METHODS: The cohort study began in 2017 and evaluated older adults (≥60 years) living in rural area. The first follow-up of the cohort was carried out between September 2018 and March 2019. Data collection at baseline and first follow-up was performed through an electronic questionnaire containing demographic, socioeconomic and health-related questions, such as alcohol and cigarette consumption, morbidities and self-perceived health status. RESULTS: At baseline, 1130 older adults were sampled, 1029 of whom were interviewed (91.1%). The age of almost 17% was 80 years or more, and 55.2% were male. At first follow-up, 862 individuals were followed (83.8%) and the characteristics of the older adults interviewed compared to those not interviewed at follow-up were similar. Between baseline and follow-up, the proportion of individuals aged 70-79 years increased, as well as the proportion of those who had consumed alcoholic beverages in the previous week and who had hypertension. The male-to-female ratio, those who were living alone, working, smokers, diabetics, who had stroke and who reported their health as being very good/good were comparable between the baseline and follow-up. CONCLUSION: With a reasonable follow-up rate, it was possible to transform a cross-sectional study into a prospective cohort study. However, new strategies will be needed to help locate participants more successfully and ensure a good response rate in future follow-ups.

Functional dependence among older adults: a cross-sectional study with a rural population of southern Brazil.

INTRODUCTION: Brazil has a rapidly aging population, yet little is known about the occurrence of functional dependence in the rural older adult population. The objective of this study was to estimate the prevalence of functional dependence and its associated factors among community-dwelling older adults in the rural area of the municipality of Rio Grande, Rio Grande do Sul state, Brazil. METHODS: This was a cross-sectional, population-based study. A systematic random sampling of households was used. Eighty percent of households in the rural area were selected, which included 1131 older adults. The outcome analyzed in this study was functional dependence. This was measured by and data were collected using the Katz Index for Activities of Daily Living (ADL) and Lawton and Brody's Scale for Instrumental Activities of Daily Living (IADL). Descriptive analysis was used to estimate the prevalence of functional dependence in ADL and IADL and to describe the sample. Crude and adjusted analysis was performed by Poisson regression with robust adjustment of variance. Prevalence ratios (PRs) and 95% confidence intervals (95%CIs) were reported. RESULTS: A total of 1029 older adults took part in this study, corresponding to an 8.9% rate of losses and refusals. Prevalence of functional dependence in ADL was 8.1% (95%CI 6.4-9.7), while prevalence of functional dependence in IADL was 32.4% (95%CI 29.5-35.2). The occurrence of functional dependence in one or more of ADL or IADL was 6.7% (95%CI 5.2-8.2). The following categories were associated with functional dependence in ADL: female sex (PR=1.70; 95%CI 1.10-2.62), age group 80 years or more (PR=3.68; 95%CI 2.20-6.16), no schooling (PR=2.61; 95%CI 1.26-5.37) and 1-4 years of schooling (PR=2.49; 95%CI 1.28-4.84), having diabetes (PR=1.85; 95%CI 1.21-2.83), depression in the previous year (PR=1.90; 95%CI 1.09-3.31), urinary incontinence (PR=3.26; 95%CI 2.06-5.16), history of stroke (PR=2.26; 95%CI 1.35-3.76) and poor/very poor self-rated health (PR=2.36; 95%CI 1.29-4.32). The following categories were associated with functional dependence in IADL: female sex (PR=1.40; 95%CI 1.19-1.65), age groups of 70-79 years (PR=1.92; 95%CI 1.51-2.43) and 80 years or more (PR=3.80; 95%CI 3.07-4.72), no schooling (PR=1.87; 95%CI 1.46-2.41) and 1-4 years of schooling (PR=1.55; 95%CI 1.22-1.96), medical diagnosis of diabetes (PR=1.33; 95%CI 1.10-1.60), urinary incontinence (PR=1.40; 95%CI 1.17-1.68), history of stroke (PR=1.41; 95%CI 1.10-1.81) and regular self-rated health (PR=1.27; 95%CI 1.06-1.52) or poor/very poor self-rated health (PR=1.80; 95%CI 1.41-2.30). CONCLUSION: Older adults in rural areas have a high prevalence of functional dependence. Knowledge of functional dependence and associated factors in rural populations is necessary for the planning and developing actions, especially in the routine of primary care, which promote health and prevent or postpone the decline in functional capacity.

Tobacco smoking prevalence and associated factors among the elderly in the rural area of Rio Grande/RS, Brazil.

INTRODUCTION: Although tobacco smoking prevalence in the adult Brazilian population is monitored through population-based surveys, the majority of findings come from studies undertaken in urban areas. Therefore, very little is known about tobacco smoking prevalence and associated factors among elderly people living in rural Brazilian areas. As such, this study aimed to assess tobacco smoking prevalence and associated factors among elderly people in the rural area of the municipality of Rio Grande, state of Rio Grande do Sul (RS), Brazil. METHODS: This was a cross-sectional population-based study conducted with individuals aged 60 years or more residing in the rural area of the municipality of Rio Grande, RS. Tobacco smoking prevalence was calculated according to each category of the independent variables of interest using Fisher's exact test. Crude and adjusted Poisson regression following a hierarchical analysis model was used to analyze associated factors. RESULTS: A total of 13.2% of the elderly people were smokers and 33.8% were former smokers. A total of 66.9% of smokers had smoked for 41 years or more and 14.4% smoked 21 or more cigarettes a day. Following the adjusted analysis, factors associated with smoking were being male (prevalence ratio (PR)=2.23, 95%CI=1.56-3.17), being in the 60-69 year age range (PR=2.65, 95%CI=1.47-4.80), having black/brown skin color (PR=1.99, 95%CI=1.34-2.93) and being single/separated (PR=1.61, 95%CI=1.15-2.25). Practicing the evangelical Christian religion was a protection factor. CONCLUSION: Although the prevalence of tobacco smoking found in this study is similar to that in other national studies with elderly people, tobacco use is still considerable and is among the main causes of avoidable diseases. This study is therefore important because it is the first conducted with elderly people living in the rural area of the municipality. Its findings can become a tool for planning actions or public policies aimed at promoting behavioral changes that reduce risk factors associated with tobacco smoking among the elderly in rural areas.

Wheezing in tobacco farm workers in southern Brazil.

BACKGROUND: Tobacco workers are exposed to several respiratory occupational sensitizers. METHODS: A representative cross-sectional study was carried out on 2469 tobacco family farming growers. Gender-stratified multivariate analyses evaluated the association between wheezing and socio-demographic, behavioral, and occupational variables. RESULTS: Wheezing prevalence was 11.0% with no difference between genders. Among men, age, smoking, strenuous work, pesticide use, contact with vegetable dust and dried tobacco dust, lifting sticks with tobacco leaves to the curing barns, and green tobacco sickness (GTS) were risk factors for wheezing. Among women, family history of asthma, tying hands of tobacco, strenuous work, contact with chemical disinfectants, and GTS were positively associated with wheezing. Harvesting lower tobacco leaves was a protective factor for the outcome in both genders. CONCLUSIONS: Pesticides, dusts exposure, and GTS were risk factors for wheezing. The synergic effect of these factors needs to be better evaluated to improve prevention.

Hyperopia: a meta-analysis of prevalence and a review of associated factors among school-aged children.

BACKGROUND: Studies show great variability in the prevalence of hyperopia among children. This study aimed to synthesize the existing knowledge about hyperopia prevalence and its associated factors in school children and to explore the reasons for this variability. METHODS: This systematic review followed PRISMA guidelines. Searching several international databases, the review included population- or school-based studies assessing hyperopia through cycloplegic autorefraction or cycloplegic retinoscopy. Meta-analysis of hyperopia prevalence was performed following MOOSE guidelines and using the random effects model. RESULTS: The review included 40 cross-sectional studies. The prevalence of hyperopia ranged from 8.4% at age six, 2-3% from 9 to 14 years and approximately 1% at 15 years. With regard to associated factors, age has an inverse association with hyperopia. The frequency of hyperopia is higher among White children and those who live in rural areas. There is no consensus about the association between hyperopia and gender, family income and parental schooling. CONCLUSION: Future studies should use standardized methods to classify hyperopia and sufficient sample size when evaluating age-specific prevalence. Furthermore, it is necessary to deepen the understanding about the interactions among hyperopic refractive error and accommodative and binocular functions as a way of identifying groups of hyperopic children at risk of developing visual, academic and even cognitive function sequelae.

Acute Pesticide Poisoning in Tobacco Farming, According to Different Criteria.

BACKGROUND: Brazil is one of the world's largest pesticide consumers, but information on pesticide poisoning among workers is scarce. OBJECTIVE: To evaluate acute pesticide poisoning among tobacco growers, according to different criteria. METHODS: This was a two-step cross-sectional study with 492 pesticide applicators. It used a 25 question pesticide-related symptoms (PRS) questionnaire and medical diagnosis for comparison with toxicological assessment. Associations were evaluated using Poisson regression. RESULTS: 10.6% reported two or more PRS, while 8.1% reported three or more. Furthermore, 12.2% received a medical diagnosis of poisoning. According to toxicologists, possible cases accounted for 14.2% and probable cases for 4.3%. PRS increased during the period of greater exposure. Those exposed to dithiocarbamates, sulfentrazone, pyrethroids, fipronil and iprodione exhibited more PRS. The number of exposure types, multi-chemical exposure, clothes wet with pesticides and spillage on the body/clothes were associated with acute poisonings. All criteria showed sensitivity greater than 79% for probable cases but only greater than 70% for medical diagnosis when compared to possible cases, presenting substantial Kappa agreement. CONCLUSION: The prevalence of acute pesticide poisoning is much higher than officially recorded. Trained physicians can screen for pesticide poisoning. It is necessary to improve workers' education to reduce pesticide use and exposure to them.

Remote work and back pain during the COVID-19 pandemic in adults and older population in South Brazil.

This article aims to investigate the association between remote work and Back Pain during the COVID-19 pandemic, and to analyze this relationship according to the body mass index. Population-based, cross-sectional study carried in two cities in southern Brazil, in individuals aged 18 years and over. Data were collected through household interviews from October to January 2020/21. Outcomes: back pain (cervical, thoracic, lumbar/acute, chronic) and pain intensity. Exposure variable: remote work. For the analyses, Poisson regression with robust adjustment for variance was used, stratified by BMI (eutrophic vs overweight/obese), and restricted to those who had worked in the past month. 1,016 had worked during the pandemic, average 42 years old (SD = 14), varying from 18 to 93 years. Remote work was performed by 7.7% of the individuals. Prevalence of back pain: 25.6% (95%CI: 19.5 to 31.7%). Overweight/obese remote workers felt pain acute cervical pain PR = 2.82 (95%CI: 1.15 to 6.92); chronic low back PR = 1.85 (95%CI: 1.04 to 3.29); acute thoracic PR = 1.81(95%CI: 3.76 to 8.68) compared to those who did not work. About one in four remote workers reported back pain during of the COVID-19 pandemic. BMI proved to be an important moderator between outcomes and exposure variable.

Blessing as a health resource: cross-sectional study with elderly residents of rural areas.

OBJECTIVE: To estimate the prevalence and factors associated with the search for folk healers for the treatment of health problems among elderly living in the rural area of the city of Rio Grande-RS. METHODS: Cross-sectional, p opulation-based study with random sampling, carried out in 2017. The outcome was analyzed in three categories (never used/used in the last 12 months/used for more than 12 months). Multinomial logistic regression was used to analyze theassociated factors. RESULTS: A total of 1,030 elderly individuals were interviewed. The prevalence of demand for folk healers in the last 12 months and for more than 12 months was 9.5% and 15.8%, respectively. In the adjusted analysis, the characteristics associated with the use of a folk healer for more than 12 months were: being in the age group of 80 years or more and having back problems and arthrosis. Following the evangelical religion was identified as a protective factor for using this resource. On the other hand, the demand for blessing in the last year was related to the age group of 70-79 years, following spiritual religions, presence of disease in the last 12 months, back problems and arthrosis, and preference for the use of urgency and emergency services. Being female was associated only with the use for more than 12 months. CONCLUSION: This study brings an original contribution to a topic poorly evaluated in epidemiological studies, because the knowledge of the frequency and determinants of the search for this type of popular therapy can be used to improve the quality and access to health services offered to the elderly population in rural areas.

Tuberculosis in prison inmates in Southern Brazil: investigating the epidemiological and operational indicators.

BACKGROUND: Tuberculosis is a worldwide public health problem and is more prevalent in specific populations, such as prisoners. The aim of this study was to analyze the epidemiological and operational indicators of tuberculosis in prisoners in a southern region of Brazil. METHODS: This was a descriptive, observational study, utilizing secondary data from the Notifiable Diseases Information System on tuberculosis cases diagnosed in prisoners in the state of Rio Grande do Sul, southern Brazil, from 2014 to 2018. Prisoner data used to calculate incidence were extracted from reports by the National Penitentiary Department. RESULTS: From 2014 to 2018, 3,557 tuberculosis cases were reported in Rio Grande do Sul prisoners. The incidence rate of tuberculosis in prisoners was 1,235/100,000 individuals in 2014 and 1,430/100,000 individuals in 2018. The proportion of new TB cases tested for HIV was high, 83.4% in this period; among those tested, 12.9% were HIV coinfected. The proportion of new cases of pulmonary tuberculosis confirmed by laboratory criteria was 52.6% in this period. In total, 18.4% of new pulmonary tuberculosis cases were initiated on directly observed treatment in this period, and 36.4% of contacts of new cases of pulmonary tuberculosis with laboratory confirmation were examined. Among retreatment pulmonary tuberculosis cases, 82.4% were laboratory-confirmed. CONCLUSIONS: Tuberculosis incidence is increasing on a per-capita and absolute basis in Rio Grande do Sul. Laboratory confirmation, HIV testing, directly observed treatment, and contact investigation rates were all low, indicating the need to improve medical and public health measures for tuberculosis control in prisons.

Psychological violence against women practiced by intimate partners: a cross-sectional study in a rural area of Rio Grande do Sul, Brazil, 2017. / Violência psicológica contra a mulher praticada por parceiro íntimo: estudo transversal em uma área rural do Rio Grande do Sul, 2017.

OBJECTIVE: To estimate prevalence and factors associated with intimate partner psychological violence against women in a rural area in the state of Rio Grande do Sul, in 2017. METHODS: This was a cross-sectional population-based study with women aged 18-49 years old and who had had an intimate partner in their lifetime. Questions from the World Health Organization Violence Against Women Study were administered. Poisson regression was used to estimate prevalence ratios (PR) and 95% confidence intervals (95%CI). RESULTS: 971 women participated. Prevalence of lifetime psychological violence was 17.2% (95%CI 14.9;19.7). Those diagnosed with depression (PR=2.23 - 95%CI 1.70;2.91) and who had consumed alcohol in the last week were more likely to refer lifetime psychological violence (PR=1.53 - 95%CI 1.07;2.17). Single women were more likely to experience psychological violence than married women (PR=1.86 - 95%CI 1.32;2.63). CONCLUSION: Psychological violence against woman in rural areas was related to mental health and alcohol use.

Child Labor in Family Tobacco Farms in Southern Brazil: Occupational Exposure and Related Health Problems.

Tobacco farming is considered Hazardous Child Labor in Brazil. This study examined the work of children and adolescents in tobacco farming, characterizing the level of urinary cotinine and the occurrence of Green Tobacco Sickness (GTS), pesticide poisoning, respiratory symptoms, and musculoskeletal disorders. A cross-sectional descriptive study was conducted with a random sample of tobacco growers under 18 years old in Southern Brazil. Ninety-nine young people were interviewed at 79 family farms. The majority began working in agriculture before they were 14 and worked harvesting and tying hands of tobacco; 60% were 16 or 17 years old, and 51.5% were male. During their lifetime, 24.5% reported GTS, and 3% reported pesticide poisoning. In the previous year, 29.3% reported low back pain, 6.1% wheezing, and 16.2% coughing without having a cold. Half of the 12 young people evaluated had over 100 ng/mL of urinary cotinine. The study indicates that child laborers do various activities and present a high prevalence of health problems. Health workers should be trained to identify child laborers and their impacts on health. Full-time farm schools could provide knowledge about sustainable agricultural production, reducing the rates of age-grade mismatch, without taking young people away from rural areas.

Epidemiology of chronic back pain among adults and elderly from Southern Brazil: a cross-sectional study.

BACKGROUND: Chronic back pain (CBP) can negatively affect one's quality of life and health condition, posing significant social and economic burdens. OBJECTIVES: (1) To determine the prevalence of CBP and analyze associated factors in adult and elderly individuals in a municipality in southern Brazil; (2) to verify who sought medical attention or missed work because of back pain; and (3) to estimate the impact of CBP on selected health outcomes. METHODS: This was a population-based cross-sectional study conducted with individuals aged 18 years and older. CBP was defined as "pain for three consecutive months in the cervical, thoracic, or lumbar regions in the last year." Demographic, socioeconomic, behavioral, and physical and mental health information was collected. The impact of CBP was assessed by the etiological fraction method. RESULTS: The prevalence of CBP was 20.7% (95% CI: 18.3, 23.0) among the 1300 study participants. The factors associated with CBP were women, elderly, smokers, obesity, and sleeping fewer hours per night, as well as those with higher mental stress levels, history of fracture, arthritis/rheumatism, and work-related musculoskeletal disorder/repetitive strain injury. One-third of those with CBP missed work (31%) and 68% visited the physician over a 12-month period. All health outcomes analyzed (poor or very poor sleep quality, regular or poor health perception, worsened quality of life, depressive symptoms, perceived sadness) were significantly associated with CBP. CONCLUSION: One in five adults or elderly reported having CBP over the previous 12 months. This condition was associated with poorer health perception, poorer quality of life, and depressive symptoms.

Suicidality among South Brazilian tobacco growers.

OBJECTIVE: To assess prevalence of suicidal ideation and suicide attempt among South Brazilian tobacco growers and to analyze the associated factors related to the suicidal ideation. METHODS: A cross-sectional study was conducted in 2011 with a random sample of 2469 tobacco growers in São Lourenço do Sul/RS. Suicidal ideation was characterized by the question "Has the thought of ending your life been on your mind?". Suicide attempt was assessed by the question "Have you ever tried to kill yourself?". Investigation of factors associated with suicidal ideation was done by means of Poisson regression. RESULTS: Prevalence of suicidal ideation and suicide attempt was 2.5 % and 1.2 % respectively. In the adjusted analysis, suicidal ideation was associated with being female, older age, moderate participation in religious activities and difficulty in paying debts. Those who worked in activities that required inadequate postures (hunched over or other forced positions), as well as farmers who performed 6-9 pesticide-related tasks demonstrated greater risk of suicidal ideation. Regarding health conditions, medical diagnosis of asthma, chronic low back pain, number of lifetime green tobacco sickness episodes and lifetime pesticide poisoning were positively associated with suicidal ideation. CONCLUSION: Suicidal thoughts and attempts are relevant mental health problems among tobacco growers. Reducing pesticide use, as well as exposure to nicotine and improving socio-economic conditions, can reduce suicidal ideation and improve the mental health of exposed workers.

[Epidemiology of Common Mental Disorders among women in the rural zones of Rio Grande, RS, Brazil]. / Epidemiologia dos Transtornos Mentais Comuns entre mulheres na zona rural de Rio Grande, RS, Brasil.

The scope of this study is to describe the prevalence and the factors associated with common mental disorders in women aged 18 to 49, residents in the rural zone of the municipality of Rio Grande-RS. A cross-sectional study was carried out with data collection conducted in 2017. A systematic sampling process of the residences of the rural area of the municipality was utilized. The General Health Questionnaire-12 (GHQ-12) was used to track common mental disorders. Crude and adjusted Poisson regression was used to estimate the prevalence ratios (PR) and respective 95% confidence intervals. The overall prevalence of Common Mental Disorders was 36.4%, being more common among women with lower levels of education, who had had an abortion and were smokers. In quantifying the occurrence and factors associated with common mental disorders in a population of women in a rural area, this study provides an original scientific contribution on the burden of this important outcome in a population that has not been studied in epidemiological surveys. The results can contribute to the health services by identifying the women most susceptible to this outcome, thus, improving the adequacy of the services offered to the health needs of rural residents.

Este estudo tem por objetivo descrever a prevalência e os fatores associados aos transtornos mentais comuns em mulheres de 18-49 anos, residentes da zona rural do município de Rio Grande-RS. Foi realizado um estudo transversal com a coleta de dados realizada no ano de 2017. Foi utilizado um processo de amostragem sistemático dos domicílios da área rural do município. Para o rastreamento dos transtornos mentais comuns utilizou-se o General Health Questionnaire-12 (GHQ-12). Foi utilizada a regressão de Poisson bruta e ajustada para estimar as razões de prevalências (RP) e os respectivos intervalos de confiança de 95%. A prevalência geral de Transtornos Mentais Comuns foi de 36,4%, sendo mais comum entre as mulheres com menor escolaridade, as que sofreram aborto e as tabagistas. Ao quantificar a ocorrência e os fatores associados aos transtornos mentais comuns numa população de mulheres de uma área rural, o presente estudo traz uma contribuição científica original sobre a carga deste importante desfecho numa população pouco estudada em inquéritos epidemiológicos. Os resultados podem contribuir com os serviços de saúde através da identificação das mulheres mais suscetíveis a este desfecho, melhorando deste modo a adequação dos serviços oferecidos às necessidades em saúde de moradores de áreas rurais.

Food insecurity in rural families in the extreme south of Brazil. / Insegurança Alimentar em famílias de área rural do extremo sul do Brasil.

This study aimed to track the prevalence of Food Insecurity (FI) and to study associated factors in households with children, women and older adults in the rural area of the city of Rio Grande, RS. This is a cross-sectional population-based study, with systematic sampling of 80% of permanently inhabited households. A short version of the Brazilian Scale of Food Insecurity (EBIA) was employed. The associated factors included data referring to the head of the household, as well as data referring to the household. The levels of prevalence and prevalence ratios and their respective confidence intervals were calculated for food insecurity through Poisson regression with robust variance. Of the 1,627 domiciles interviewed, 26% were in an FI situation, and households that included three populations were higher. The most affected domiciles were those in which the head of the household had less than four years of schooling, with more residents, without animal husbandry, belonging to the lowest income quartile and receiving family grants ("Bolsa Família" Program). This study showed the relevance and magnitude of the FI problem in the rural region of Rio Grande since knowledge about the actual FI prevalence of this region is unknown.

O estudo objetivou rastrear a prevalência de Insegurança Alimentar (IA) e estudar fatores associados em domicílios com crianças, mulheres e idosos na área rural do município de Rio Grande, RS, em 2017. Foi um estudo transversal com amostragem sistemática de 80% dos domicílios permanentemente habitados. Utilizou-se uma versão reduzida da Escala Brasileira de Insegurança Alimentar (EBIA). Os fatores associados contemplaram dados referentes ao chefe da família, além de dados referentes ao domicílio. Prevalências e Razões de Prevalências e seus respectivos Intervalos de Confiança foram calculadas para a IA por meio da Regressão de Poisson com variância robusta. Dos 1.627 domicílios entrevistados, 26% se encontraram em situação de IA, sendo maior naqueles domicílios que continham as três populações. Os domicílios mais atingidos foram os que o chefe da família tinha menor escolaridade, maior número de moradores, sem criação de animais, pertencentes ao menor quartil de renda e que recebiam Bolsa Família. Esse estudo mostrou a importância e a dimensão do problema da IA na região rural de Rio Grande, já que o conhecimento da real prevalência de IA nessa região é desconhecido.

Access to Primary Health Care by older adults from rural areas in Southern Brazil.

OBJECTIVE: To characterize the access and use of health services considered reference among the older rural population from a municipality in southern Brazil, whose rural area has full coverage of the Family Health Strategy (FHS), investigating factors associated with the choice of the Basic Family Health Unit (BFHU) as reference. METHODS: This is a cross-sectional study conducted in 2017 with systematic sampling of rural households in the municipality of Rio Grande (RS) using a standardized in-house questionnaire. We performed descriptive analyses of sociodemographic profile, type of reference service chosen, and reasons for choosing/using the prime-choice service and the nearest BFHU. Poisson regression was used to investigate factors associated with the type of reference service chosen. RESULTS: Among the 1,030 older adults who participated in the study, 61.4% considered the BFHU a prime choice/reference service mostly due to its proximity (82.6%); the others sought other places due to a greater ease (34.6%) and resoluteness (52.6%). Almost ⅔ of the respondents sought care at the BFHU during the last year, and the reasons differed among those who considered the unit as reference (chronic disease) and those who sought another place (procedures). We also found that the lower the age, income, education, and household-unit distance, the greater the likelihood of the older adult considering the nearest BFHU as reference service. CONCLUSIONS: The FHS has reached the vulnerable older rural population, approaching an equitable public health system. However, further evaluations are necessary to verify the quality and adequacy of care, given that social structure, enabling factors (such as economic condition), and possible beliefs regarding health still establish the standards for choosing a service.

Sedentary behavior in elderly residents from the rural area in Southern Brazil. / Comportamento sedentário em idosos residentes de zona rural no extremo Sul do Brasil.

INTRODUCTION: Sedentary behavior has been associated with several health indicators. This study aims to describe this outcome in elderly people living in rural areas. METHODOLOGY: A cross-sectional study was carried out with elderly people from the rural area in the city of Rio Grande/RS, in 2017. Data were collected using an electronic questionnaire. Sedentary behavior was evaluated by eight aspects: watching television/videos/DVDs, using computer/internet, reading, socializing with friends and/or family, driving or riding a car/bike/taking public transport, practicing a hobby, working, and other activities. The analysis was composed by the description of aspects and multivariable (linear regression) analysis to test associations between the outcome and socioeconomic, demographic and physical activity characteristics. Association of the excess of sedentary behavior and time watching television within the independent variables was also verified. RESULTS: The mean of sedentary behavior was 274.9 minutes/day (n = 1,030), but watching television represented almost half (130.5 minutes/ day). Age was inversely associated with sedentary behavior, while income and schooling presented a direct relation. Income had a positive association with excessive sedentary behavior and time watching television. CONCLUSION: The mean sedentary behavior was lower when compared with the literature for the elderly. We suggest that actions to encourage healthy habits aim especially at reducing the time spent watching television.

INTRODUÇÃO: O comportamento sedentário tem sido associado a diversos indicadores de saúde. O objetivo deste estudo é descrever esse desfecho em idosos residentes de zona rural. METODOLOGIA: Realizou-se um estudo transversal com idosos da zona rural de Rio Grande/RS, em 2017. A coleta de dados foi realizada por meio de questionário eletrônico. O comportamento sedentário foi avaliado pelo somatório de oito aspectos: assistir a televisão/vídeos/DVD, usar computador/internet, ler, socializar com amigos e/ou família, dirigir ou andar de carro/moto/transporte público, praticar algum hobby, trabalhar e outras atividades. A análise deu-se pela descrição dos aspectos e pela análise multivariável (regressão linear), para testar associações com características socioeconômicas, demográficas e atividade física. Também foi verificada associação do excesso de comportamento sedentário e tempo assistindo à televisão com as variáveis independentes. RESULTADOS: A média de comportamento sedentário foi de 274,9 minutos/dia (n = 1.030), e assistir televisão representou quase a metade (130,5 minutos/dia). Idade mostrou-se inversamente associada com o comportamento sedentário, enquanto renda e escolaridade apresentaram uma relação direta. Renda apresentou associação positiva com excesso de comportamento sedentário e tempo assistindo televisão. CONCLUSÃO: A média de comportamento sedentário foi menor quando comparada com a literatura em idosos. Sugere-se que ações para incentivar hábitos saudáveis visem especialmente diminuir o tempo assistindo televisão.
