Partial recording protocols for periodontal disease assessment in epidemiological surveys.

The objective of the present study was to compare the reliability of four partial-mouth protocols for assessing shallow, moderate, and deep sites for periodontal pocket depth and clinical attachment levels. Periodontal pocket depth and clinical attachment level measurements were recorded for 156 subjects (age > or = 30). The four models of partial-mouth protocols compared were: Model I: all sites per tooth in the random half-mouth protocol randomly selecting one maxillary and mandibular quadrant, Model II: buccal sites in a full-mouth protocol, Model III: buccal sites in the random half-mouth protocol randomly selecting one maxillary and mandibular quadrant, Model IV: all sites per tooth using Community Periodontal Index teeth. In comparison with full mouth examination, Model I did not show significant differences for periodontal pocket depth and clinical attachment level parameters. Models II and III were different for some periodontal pocket depth means, and Model IV significantly overestimated all clinical parameters related to periodontal disease. Model I appears to be adequate to substitute for the full-mouth examination to assess the prevalence and severity of chronic periodontal disease in adults.

[Consequences of sociodemographic inequalities on birth weight].

OBJECTIVE: To analyze sociodemographic inequalities in prenatal and childbirth care and their consequences on birth weight. METHODS: The study was based on a sample of 10,072 postpartum women treated at public (those outsourced by the National Health System) and private maternity hospitals in Rio de Janeiro, Brazil, from 1999 to 2001. To test the association between birth weight and maternal sociodemographic and biological characteristics and prenatal care (modified Kotelchuck index), postpartum women were stratified by level of schooling and two multiple linear regressions were performed. The bootstrap technique was used in addition to accurate confidence intervals for the estimated effects. RESULTS: For nearly all of the variables analyzed in the bivariate analysis, birth weight was lower among children of mothers with low schooling. In the multivariate analysis, among women with low schooling, there was a direct association between birth weight and the modified Kotelchuck index and gestational age. The variables black skin color, smoking, and history of premature birth were negatively associated with birth weight, while maternal age and parity showed distinct behaviors from the central range of data at the extremes. In the group with high schooling, only parity, gestational age, and modified Kotelchuck index were significant and directly associated with birth weight. The protective effect of prenatal care was observed, as well as the negative effect of smoking, regardless of the mother's level of schooling. CONCLUSIONS: The variables associated with neonates' birth weight of mothers with high schooling in Rio de Janeiro were biological, in contrast to the social determinants in the group with low schooling.

[Evaluation of antenatal peregrination in a sample of postpartum women in Rio de Janeiro, Brazil, 1999/2001].

The access to obstetric care in the city of Rio de Janeiro, Brazil, was evaluated in this study. The aim of this article was to determine the social, demographic and obstetric factors associated with the antenatal search for health services, in a sample of 6,652 postpartum women. It was observed that 1/3 of patients have to search for services in more than one hospital, not uncommonly in 3 or more. It is important to consider that only 1/5 of these patients are transferred by ambulance. The factors associated with this peregrination were: place of residence, birth weight, age, skin color, marital status and residence in places where garbage is not picked up. There was no association with schooling; Kotelchuck modified index, obstetric risk, water source and residence in slums.

[Hospital Information Systems and their application in public health].

The objective of this study was to survey the scientific production of applications for data from the Hospital Information System of Brazil's Unified National System (SUS) in analyses of relevant Public Health issues. To find articles published in scientific journals from 1984 to 2003, the authors consulted the SciELO, MEDLINE, and Virtual Public Health Library databases. To locate monographs, theses, and dissertations, the authors consulted the websites of institutions providing Master's and doctoral courses in Public Health. A total of 76 articles were identified for the reference period, and they were classified into five categories with different analytical approaches. Although the Hospital Information System in the SUS has incomplete coverage and there are uncertainties about the reliability of its data, the range of studies showed internal consistency with current knowledge, reinforcing the system's importance and the need to understand its strengths and weaknesses.

[Perinatal deaths and childbirth healthcare evaluation in maternity hospitals of the Brazilian Unified Health System in Belo Horizonte, Minas Gerais, Brazil, 1999].

This paper analyzes the association between perinatal mortality and factors related to hospital care during labor, considering that healthcare assessment is needed in order to reduce perinatal mortality. A population-based case-control study was conducted with 118 perinatal deaths (cases) and 492 births (controls) that took place in maternity hospitals of the Brazilian Unified Health System (SUS) in Belo Horizonte, Minas Gerais, Brazil. Male sex, prematurity, diseases during pregnancy, low birth weight, newborn diseases, lack of prenatal care, lack of partograph use during labor, and less than one fetus assessment per hour during labor were significantly associated with perinatal deaths. In the multiple regression analysis, lack of partograph use during labor and type of hospital were associated with perinatal deaths. These results indicate inadequate quality of care in maternity hospitals and show that health services structure and health care process are related to perinatal mortality due to preventable causes.

Healthy lifestyles and access to periodic health exams among Brazilian women.

Using data from the World Health Survey carried out in Brazil in 2003, this paper has the objective of describing the sociodemographic profile of Brazilian women (age 18-69 years of age) that have adequate health care, not only with respect to health service utilization but also to healthy lifestyles. Sociodemographic variables (age, marital status, race, education level, number of household assets, and occupation), health care variables (periodic gynecologic exam with Papanicolaou, mammography among women aged 40-69 years, body mass index, smoking, alcohol, physical activity, dental care, private health insurance), and self-rated health were analyzed by municipality size strata. Logistic regression models were used to identify the characteristics of women that have adequate health care. Coverage of periodic gynecologic exam with Papanicolaou was 65.0% and mammography coverage was 47.0%. Less than 20.0% of Brazilian women have adequate care, and the most associated factors were: being younger than 40 years old, having higher educational level, having private health insurance and being married. The results indicate the need to develop health promotion policies focused on modifying the risk habits and risk practices to health, and to stimulate preventive periodic health exams.

Periodontal infection and adverse pregnancy outcomes: a systematic review of epidemiological studies.

The objective of this systematic review was to evaluate analytical studies on periodontal disease as a possible risk factor for adverse pregnancy outcomes. A literature search of the MEDLINE, SciELO, and LILACS bibliographic databases and CAPES thesis database was conducted up to December 2005, covering epidemiological studies of periodontal disease and adverse pregnancy outcomes. Of the 964 papers identified, 36 analytical studies met the inclusion criteria. Twenty-six epidemiological studies reported associations between periodontal disease and adverse pregnancy outcomes. There was a clear heterogeneity between studies concerning measurement of periodontal disease and selection of type of adverse pregnancy outcome. Therefore no meta-analysis was performed. Most studies did not control for confounders, thus raising serious doubts about their conclusions. The methodological limitations of most studies did not allow conclusions concerning the effects of periodontal disease on adverse pregnancy outcomes. Larger and methodologically rigorous analytical studies using reliable outcomes and exposure measures are recommended.

Congenital malformations in Rio de Janeiro, Brazil: prevalence and associated factors.

This study aims to estimate the prevalence of congenital malformations and their correlation with socioeconomic and maternal variables. The design was cross-sectional, based on a sample of 9,386 postpartum women after admission for childbirth in maternity hospitals in the city of Rio de Janeiro, Brazil. Data were collected through interviews with mothers in the immediate postpartum, as well as by consulting the patient records of both the mothers and newborn infants. Prevalence of congenital malformations at birth was 1.7%, and minor malformations were the most frequent. Neural tube defects were the most frequent major malformations. According to multivariate analysis, congenital malformations were statistically associated with: maternity hospitals belonging to or outsourced by the Unified National Health System (SUS) and inadequate prenatal care (<or= 3 visits). This study highlights the importance of measures for health promotion and disease prevention in childbearing-age women, with special attention to prenatal care and childbirth, which can directly influence neonatal indicators and prevention of birth defects.

[Perinatal mortality due to congenital syphilis: a quality-of-care indicator for women's and children's healthcare].

Syphilis is a persistent cause of perinatal mortality in Rio de Janeiro, Brazil, where this study was performed using data from the mortality data system and investigational reports for fetal and neonatal deaths, mandatory in municipal maternity hospitals. From 1996 to 1998, 13.1% of fetal deaths and 6.5% of neonatal deaths in municipal maternity hospitals were due to congenital syphilis. From 1999 to 2002, the proportions were 16.2% and 7.9%, respectively. For the city of Rio de Janeiro as a whole from 1999 and 2002, the proportions were 5.4% of fetal deaths and 2.2% of neonatal deaths. The perinatal mortality rate due to congenital syphilis remains stable in Rio de Janeiro, despite efforts initiated with congenital syphilis elimination campaigns in 1999 and 2000. We propose that the perinatal mortality rate due to congenital syphilis be used as an impact indicator for activities to control and eliminate congenital syphilis, based on the investigational reports for fetal and neonatal deaths. Such reports could be extended to the surveillance of other avoidable perinatal disease outcomes.

[Racial, sociodemographic, and prenatal and childbirth care inequalities in Brazil, 1999-2001].

OBJECTIVE: To analyze social inequalities and inequalities in access to and utilization of health care services according to skin color in a representative sample of postpartum women receiving hospital childbirth care. METHODS: A cross-sectional study was carried out in a sample of 9,633 postpartum women, of whom 5,002 were white (51.9%), 2,796 mulatto (29.0%), and 1,835 black skin color (19.0%), seen in public maternity hospitals, hospitals contracted out by the Unified National Health System, and private hospitals in the period 1999-2001. Data were collected from medical records and through interviews with the mothers in the immediate postpartum period using standardized questionnaires. Statistical analyses were performed using chi(2) tests to assess homogeneity of proportions and Student's t-test for comparison of measures. The analysis was stratified by maternal schooling. RESULTS: A persistent unfavorable situation was seen for mulatto and black women as compared to white women. Mulatto and black women had the highest rates of adolescent mothers, low schooling, unpaid occupation, and not having a partner. History of physical violence, smoking, attempts to interrupt pregnancy, and visits to several hospitals before being admitted were more frequent among black women, followed by mulatto and then white women of low schooling. High schooling group of women showed better indicators but the same pattern was seen. This variability is also seen in the opposite direction in terms of the level of satisfaction with prenatal and childbirth care. CONCLUSIONS: It was distinguished two forms of discrimination, by educational level and skin color, in care delivered by health services to postpartum women in Rio de Janeiro.

Association between gestational night blindness and serum retinol in mother/newborn pairs in the city of Rio de Janeiro, Brazil.

OBJECTIVE: Gestational night blindness (XN) is associated with increased risk of reproductive morbidity and mortality. This study investigated the prevalence of gestational XN among postpartum women treated in a public maternity hospital in the city of Rio de Janeiro, Brazil and evaluated its association with maternal and neonatal (cord blood) serum retinol concentrations. METHODS: XN was evaluated retrospectively, using an interview according to guidelines of the World Health Organization, in 222 postpartum women (< or = 6 h after delivery) after singleton births who had low obstetric risk. Serum retinol concentrations were measured according to the modified Bessey method, with a cutoff point lower than 1.05 micromol/L for inadequate serum retinol concentration. RESULTS: Prevalence of gestational XN was 18%, and inadequate maternal and cord blood serum retinol concentrations were found in 24.4% and 45.5% of samples, respectively. The results associated gestational XN with inadequate maternal serum retinol concentration (P = 0.000), and an association was observed between maternal and neonatal serum retinol concentrations (P = 0.000). A poor association was observed between maternal XN and serum levels of retinol in newborn children (P = 0.06). CONCLUSIONS: The results suggest that prevalence of gestational XN and inadequate serum retinol concentration among postpartum women and newborns is a concern, calling attention to the need for studies in other parts of Brazil. In addition, the risk of inadequate serum retinol in newborns was significantly higher among infants of postpartum women with serum retinol levels below 1.05 micromol/L. Gestational XN was associated with inadequate levels of maternal serum retinol, and the results suggest a poor relation between maternal XN and vitamin A nutritional status of newborns.

[Factors associated with perinatal morbidity and mortality in a sample of public and private maternity centers in the City of Rio de Janeiro, 1999-2001].

This study compares socio-demographic factors, mothers' biological characteristics, and quality of care at maternity hospitals in the City of Rio de Janeiro, Brazil. A sample of 10,072 post-partum women in 47 hospitals was selected. Data were collected by interviewing mothers in the immediate post-partum and from medical records. The chi2 test was used to analyze homogeneity of ratios. Significant differences were found between patients in public and private hospitals in relation to family support, healthy habits during pregnancy, reproductive history, access to and satisfaction with prenatal care and delivery, and particularly adverse effects in the newborns. Private maternity hospitals showed better results, although they displayed excessive cesarean and neonatal inter-hospital transfer rates. The stratum consisting of public Federal and State maternity hospitals received women with greater morbidity, had lower neonatal transfer rates, and received a more positive assessment by clients of the Unified National Health System (SUS). Private maternity centers contracted out by the SUS were the ones that most refused treatment to patients, leading to delays in patient care for delivery.

[Consistency between data sources and inter-observer reliability in the Study on Neonatal and Perinatal Morbidity and Mortality and Care in the City of Rio de Janeiro].

The objective of this study was to evaluate the quality of data in the research project entitled "Study on Neonatal and Perinatal Morbidity and Mortality and Care in the City of Rio de Janeiro", analyzing the completeness of patient records, inter-observer reliability, and concordance of collected data. The study interviewed a sample of 10,072 post-partum women, corresponding to 10.0% of the deliveries in the City of Rio de Janeiro. This article analyzed the concordance between data on patient records and the reproducibility of questionnaires by mean of rest/ retest, using common and prevalence-adjusted Kappa as well as the intra-class correlation coefficient. Losses totaled 4.5%, and the proportion of unknown data on patient records varied from 3.0 to 90.0%. Lower proportions were concentrated in the neonatal assessment and higher ones in the data on maternal hospital admission. There was a high concordance between the data reported by the mother and that written on the patient record, with the Kappa varying from 0.77 to 0.96. In the test/retest verification, Kappa varied from 0.61 to 0.94. This study demonstrated a high inter-observer reliability as well as reliability between the different data sources (interviewee and patient record).

[Socioeconomic inequalities and low birth weight and perinatal mortality in Rio de Janeiro, Brazil].

Socioeconomic inequalities in early infant mortality have been evidenced in Brazil, with a greater mortality risk associated with the mother's socioeconomic status (SES). The aim of this paper is to identify socioeconomic inequalities in relation to low birth weight and perinatal mortality in the City of Rio de Janeiro, Brazil, discussing the appropriateness of the main health inequality indexes proposed in the international literature. As the information source, we use data collected in a survey of approximately 10,000 mothers selected for interview within 48 hours after delivery in public and private hospitals in the city. Using educational level and head of household's income as indicators of SES, as well as population attributable risk and slope index of inequality as health inequality measures, the results show a steep socioeconomic gradient in the proportion of low birth weight, and especially in the perinatal mortality rate. The persistent association between socioeconomic indicators and adverse results in pregnancy indicates (at least partially) the health system's inefficacy in diminishing perinatal health inequalities in Rio de Janeiro.

[Aspects of women's satisfaction with childbirth care in a maternity hospital in Rio de Janeiro].

The objective of this study was to evaluate factors associated with women's satisfaction with vaginal delivery at the Leila Diniz Maternity Hospital in Rio de Janeiro, Brazil. A cross-sectional study was conducted from March 1 to 30, 1999, using interviews with women who had undergone vaginal delivery. In order to analyze women's satisfaction, the following were used: (a) a scale to evaluate overall satisfaction with the birthing process; (b) description of the woman's reasons for this evaluation; and (c) analysis of factors associated with the evaluation of childbirth satisfaction. Chi-square for trend with a 5% significance level was used to analyze the results. The results of the study showed high satisfaction with childbirth care (67%), determined mainly by short labor time, good treatment by staff, low level of distress, absence of complications for the mother and baby, and presence of a family companion. The study also verified the association between women's satisfaction with information received during perinatal care and positive perceptions of the professionals responsible for providing care.

[Use of the modified Kotelchuck index in the evaluation of prenatal care and its relationship to maternal characteristics and birth weight in Rio de Janeiro, Brazil].

The Kotelchuck index (KI) was modified and used to evaluate prenatal care provided in the City of Rio de Janeiro, Brazil, in a sample of 9,920 post-partum women following singleton deliveries. Ordinal logistic regression (OLR) and multivariate linear regression (LMR) were used to estimate the importance of demographic, psychosocial, and obstetric factors for modified KI and the effects on birth weight (BW), respectively. Only 38.5% of the sample was classified as having received adequate or intensive prenatal care. After adjusting for other predictors, the explanatory variables for KI were: mother's schooling, living with the newborn's father, attempted abortion, diabetes mellitus, satisfaction with pregnancy, skin color, parity, age, and place of residence. BW was associated with the modified KI, even after controlling for socio-demographic, behavioral, and biological variables. Adequate utilization of prenatal care in the City of Rio de Janeiro contributed to the prevention of low BW, and the mothers who used prenatal services less presented worse conditions in terms of socioeconomic status, schooling, family support, and obstetric risk.

[Prescribed and reported drug use during pregnancy].

Few studies describe drug utilization in pregnancy focusing on prescribing practices. This study is part of a larger survey on perinatal care in the City of Rio de Janeiro, Brazil. The type of hospital (public, contracted out by the Unified National Health System, or private) determined the stratification of 10,072 hospitalized post-partum women, who were asked about medication used during pregnancy. Hospital records supplied information on drugs prescribed during labor. Drugs were classified according to the Anatomical Therapeutic Chemical (ATC) system. Another system was used for specific cases of referred use. A mean of 2.08 drugs was prescribed during labor, and a mean of 2.3 was reported during pregnancy. Anesthetics, antibiotics, oxytocin, and analgesics were the most frequently prescribed during labor, with significant differences between strata. Ferrous sulfate, vitamins, scopolamine, and acetaminophen were the main drugs reported during pregnancy. Women who had attempted abortion referred use of various kinds of tea (49.7%) and misoprostol (9.2%). The drug utilization pattern was consistent with the literature. This study offers knowledge on prescribing patterns during labor and self-reported use during pregnancy in both the public and private sectors.
