Minor psychiatric disorders among Brazilian ragpickers: a cross-sectional study.

BACKGROUND: Ragpickers are informal workers who collect recyclable materials to earn a small wage. Their life and working conditions are extremely difficult. We examined minor psychiatric disorders (MPD) among a cohort of ragpickers in Pelotas, a city in southern Brazil. METHODS: Ragpickers were matched by sex, age, and years of schooling with a sample of non-ragpickers from the same poor neighborhoods. The cross-sectional study gathered data by interview on 990 individuals in 2004. MPD were assessed using a standard self-reporting questionnaire, the SRQ-20. RESULTS: The prevalence of MPD among ragpickers was 44.7%, higher than reported by neighborhood controls (33.6%; p < 0.001). MPD were more common among females, those of lower economic level, smokers and alcoholics. Among occupational characteristics, MPD prevalence was associated with frequent static postures, low job satisfaction and recent work accidents. CONCLUSION: Ragpickers more frequently report MPD than other poor workers living in the same neighborhoods, with many of the same life conditions. Improving the work lives of these precarious workers should address not only the physical hazards of their jobs but their mental and emotional health as well.

[Knowledge about contraceptives in a population 15 years or older in a southern Brazilian city].

In Brazil, prevalence of contraceptive use is high, but incorrect and inappropriate use is frequent, suggesting limited knowledge about methods. This study thus evaluated the knowledge about the most widely used contraceptive methods, measured through a score (0-10) and related factors. A population-based cross-sectional study was performed, with 3,542 subjects ages 15 or older, residing in the urban area of Pelotas, Rio Grande do Sul State. The mean overall knowledge score was 4.65 (sd = 2.07): 5.02 (sd = 2.10) for women and 4.18 (sd = 1.92) for men. Lower age, higher schooling, a report of unwanted pregnancy, and any lifetime use of contraceptive methods (exclusive or combined) were associated with higher knowledge scores among men, while for women, the determinants of higher knowledge were higher age, living with a partner, higher schooling, higher socioeconomic status, not reporting a religion, and any lifetime use of contraceptive methods (exclusive or combined). Despite high prevalence of any lifetime contraceptive use (75.3%), knowledge is still limited about the most widely used methods, as well as about the menstrual cycle and fertile period.

[Population study of premenstrual syndrome].

OBJECTIVE: To study the prevalence of premenstrual syndrome and the factors associated with this, by comparing the obtained frequency with the self-reported frequency. METHODS: This was a cross-sectional population-based study, involving 1,395 women aged 15 to 49 years old in a medium-sized municipality in Southern Brazil, carried out in 2003. Questionnaires were applied to measure the prevalence of premenstrual syndrome by means of a score based on five premenstrual symptoms that interfered with family life or led to absence from work or school. Associations with socioeconomic, demographic and behavioral variables were investigated. Self-reported syndrome was investigated with regard to its sensitivity and specificity, taking the score as the gold standard. The statistical analyses performed were Pearson chi2, Mantel-Haenszel and Poisson regression, with Kappa coefficients to verify the concordance of the responses. RESULTS: The obtained prevalence was 25.2% (95% CI: 22.5-27.9) and the self-reported prevalence was 60.3% (95% CI: 57.4-63.3). The principal premenstrual symptoms found were: irritability, abdominal discomfort, nervousness, headache, fatigue and breast pain; all of these showed prevalence of over 50%. Higher risk was presented by women of higher socioeconomic level, better schooling level, aged under 30 years and with white skin color. Psychotropic drug users and women who were not using any hormonal contraceptive presented higher prevalence of the syndrome. The sensitivity of the test was 94%, specificity 51% and accuracy 62%. CONCLUSIONS: A high prevalence of premenstrual syndrome was found. Even though the women's perception of the syndrome was higher than the result measured by the symptom score, one quarter of the women presented this health problem.

Pesticides and respiratory symptoms among farmers.

OBJECTIVE: Despite the intensive use of pesticides in agriculture there are few studies assessing the risk of respiratory conditions from this exposure. The study aimed at quantifying the prevalence of respiratory symptoms among farmers and evaluating its relationship with occupational use of pesticides and the prevalence of respiratory symptoms. METHODS: A cross-sectional study was conducted among 1,379 farmers from two municipalities of Southern Brazil in 1996. Frequency and type of chemical exposure and pesticide poisoning were recorded for both sexes. All subjects aged 15 years or older with at least 15 weekly hours of agricultural activity were interviewed. An adapted questionnaire developed by the American Thoracic Society was used for the assessment of respiratory symptoms. Multivariate logistic regression analysis was carried out. RESULTS: More than half (55%) of interviewees were male. The prevalence of asthma symptoms was 12% and chronic respiratory disease symptoms was 22%. Higher odds ratios for both asthma (OR=1.51; 95% CI: 1.07-2.14) and chronic respiratory disease (OR=1.34; 95% CI 1.00-1.81) symptoms were found in women. Logistic regression analysis identified associations between many forms of exposure to pesticides and increased respiratory symptoms. Occurrence of pesticide poisoning was associated with higher prevalence of asthma symptoms (OR=1.54; 95% CI: 1.04-2.58) and chronic respiratory disease symptoms (OR=1.57; 95% CI: 1.08-2.28). CONCLUSIONS: In spite of causality limitations, the study results provide evidence that farming exposure to pesticides is associated with higher prevalence of respiratory symptoms, especially when the exposure is above two days per month.

Work and behavioural problems in children and adolescents.

METHODS: We conducted a cross-sectional study of 3139 children and adolescents from poor areas of the city of Pelotas, southern Brazil. We employed the child behaviour checklist for estimating BP. We performed multivariable analysis using Poisson's regression for confounder control. RESULTS: The proportion of workers was 13.8% (7.3% among children and 20.7% among adolescents). Prevalence of BP among workers and prevalence ratios (PRs) were 21.4% (PR = 1.3; CI 0.9-1.9) among children and 9.5% (PR = 0.6; CI 0.4-1.0) among adolescents. Considering workers only, the risk of BP was 2.7 times greater (CI 1.4-5.1) among children when compared with adolescents. Working in domestic services among children and beginning to work at an early age among adolescents were associated with BP. CONCLUSIONS: Our results reinforce the need for respecting the minimum age for admission to employment established by the ILO Convention 138 and by the Brazilian legislation and contribute to the discussion about the occupations that should be considered as hazardous child labour.

[Rural work and pesticide poisoning].

Pesticide use is intensive in Brazilian agriculture. Population-based studies on the characteristics of pesticide use and pesticide poisoning are scarce. This study describes the profile of occupational exposure and pesticide poisoning incidence. Farm characteristics and pesticide occupational exposure were evaluated using a cross-sectional design. Among 1,379 farmers/farm workers, annual incidence of pesticide poisoning was 2.2 episodes per 100 exposed. Based on Poisson regression, applying pesticide, reentering crop fields after spraying, and working with pesticides on more than one farm were the types of exposure that presented a positive correlation with pesticide poisoning. The results may be useful for planning activities aimed at reducing occupational pesticide poisoning among rural workers.

[Chronic low back pain in a Southern Brazilian adult population: prevalence and associated factors].

To identify the prevalence of chronic low back pain (CLBP) and examine factors associated with this condition in a Southern Brazilian adult population, a population-based cross-sectional study was conducted, including 3,182 subjects of both sexes, aged 20 years or over, living in the urban area of Pelotas, Rio Grande do Sul State. The questionnaire included socio-demographic, behavioral, and nutritional variables, as well as characterization of exposure to ergonomic factors in daily activities. CLBP prevalence was 4.2%. The variables sex, age, marital status, schooling, smoking, body mass index, working in a lying position, heavy physical work, and repetitive movements were associated with CLBP. Prevalence of CLBP is important as it limits normal activities and increases the use of health care services. There may be differences in the ergonomic risk factors for CLBP and low back pain in general.

[Sexually transmitted diseases symptoms in adults: prevalence and risk factors].

OBJECTIVE: To evaluate the prevalence of sexually transmitted disease (STD) symptoms and associated risk factors in an adult population. METHODS: A population-based cross-sectional study was conducted among residents of the metropolitan area of Pelotas, Brazil. Subjects were 20 years old or more. A self-administered questionnaire was used to gather information about sexual behavior and STD symptoms. Multivariate analysis was undertaken using logistic regression. RESULTS: The prevalence of STDs was 13.5%. A higher risk of STDs was found in non-white younger women with more sexual partners and who did not use condoms in their last sexual relationship. Among men, early initiation of sexual activity and anal sex were positively associated with the outcome. Higher risks were found among women with lower schooling. CONCLUSIONS: The present study identified a significant prevalence of STD symptoms in this population and showed differences in risk factors according to gender. Since many STDs are asymptomatic and symptomatic cases are often either not perceived as disease by patients or not diagnosed in health services, the actual prevalence may be even greater. The study results suggest that cohabitation with a sexual partner does not reduce the risk of STDs in this population and showed sex differences for risk factors, both of which should be taken into account while approaching this issue.

[Software program to systematize data for planning public health actions].

OBJECTIVE: To describe and evaluate a software program to provide basic health care teams with primary health services data. METHODS: It was described the PACOTAPS (software program for primary health care), developed using Visual Basic 5.0, and secondary data and outpatient care demand modules were tested in a basic health care unit in Pelotas, Brazil. Age/gender structure of the reference population was obtained from secondary data. Outpatient care demand allowed the characterization of all 4,170 visits carried out in a month by analyzing Outpatient Care Files. RESULTS: Age and gender distribution as well as main diagnoses and referrals were identified for all patients seen at the health care unit. In addition, there were detected differences among the health care centers due to either different organization and care models or as a result of different actual needs of improvement in patient register systems. CONCLUSIONS: PACOTAPS, a user-friendly software program, can contribute to health care unit management evaluation within the national Unified Health System (SUS). The availability of an electronic tool combining resources allows decision making in healthcare facilities, and even at municipal health policy level, to be based on more adequate and effective data.

Child labor and musculoskeletal disorders: the Pelotas (Brazil) epidemiological survey.

OBJECTIVES: [corrected] This article describes the prevalence of musculoskeletal pain in several anatomic sites in children and teens, and investigates, while adjusting for potential confounders, the association between musculoskeletal pain and back pain and the following: age, gender, sports practice, use of computer/video games/television, school attendance, intensity of involvement in household domestic activities, care of other children, care of sick/elderly family members, work activities, and workloads. METHODS: We conducted a cross-sectional study interviewing 3,269 children aged 10-17 years in the low-income areas of Pelotas, Brazil. RESULTS: The prevalence of pain in the neck, knee, wrist or hands, and upper back exceeded 15%. Workers in manufacturing had a significantly increased risk for musculoskeletal pain (prevalence ratio [PR]=1.31) and for back pain (PR=1.69), while workers in domestic service had 17% more musculoskeletal pain and 23% more back pain than nonworkers. Awkward posture (PR=1.15) and heavy physical work (PR=1.07) were associated with musculoskeletal pain, while monotonous work (PR=1.34), awkward posture (PR=1.31), and noise (PR=1.25) were associated with back pain. CONCLUSIONS: Musculoskeletal pain is common among working children and teens. Knowledge of occupational risk factors can support actions to restructure work conditions to reduce or eliminate childhood exposure to hazardous conditions. Our results suggest that strategies to prevent musculoskeletal disorders in child workers should be developed.
