Survey of calcium supplementation to prevent preeclampsia: the gap between evidence and practice in Brazil.

BACKGROUND: Preeclampsia is a major cause of maternal and perinatal morbidity and mortality worldwide and especially in Latin America. High quality evidence indicates that calcium supplementation during pregnancy significantly reduces the incidence of preeclampsia and its consequences, including severe maternal morbidity and death. Few studies have assessed the implementation of this intervention in clinical practice. The study aimed to assess the proportion of pregnant women who received calcium supplements in Brazilian public antenatal care clinics. METHODS: This cross-sectional study interviewed women waiting for antenatal care visits in 9 public clinics in 4 Brazilian cities in 2010-2012. Trained interviewers used a standardized anonymous questionnaire to collect socio demographic and obstetric data, information on ingestion of dairy products and on prescriptions received during current pregnancy. RESULTS: A total of 788 valid questionnaires were analyzed. Participants were young (mean age 25.9), mostly multiparous (71.3%) and in the 2nd or 3rd trimesters of pregnancy at the time of interview (87.6%). Only 5.1% (40/788) had received a prescription for calcium supplements. Based on their reported ingestion of dairy products, the mean daily dietary calcium intake of the participants was 210 (+ 265) mg/day and over 90% consumed less than 1 g of calcium/day. CONCLUSIONS: Despite good quality evidence indicating the benefits of this practice especially for women with low calcium diets, less than 6% of a sample of women receiving antenatal care in Brazilian public clinics received a prescription for calcium supplements. There is an urgent need to upscale the implementation of this life-saving intervention.

Brazilian health technology assessment bulletin: editorial process, dissemination strategies, critical appraisal, and initial impact.

OBJECTIVES: This study reports on the Brazilian experience of developing a specialized bulletin, the Brazilian Health Technology Assessment Bulletin (BRATS), on health technology assessments (HTA). METHODS: The editorial process, format, and dissemination strategy of the publication are presented. A critical appraisal of the available issues was made using the checklist for HTA reports of the International Network of Agencies for Health Technology Assessment. The initial impact was estimated based on a retrospective observational measurement of the types of publications that cite the bulletin as a source of information. The publications citing BRATS were identified using Google Scholar. RESULTS: Since June 2008, fourteen issues of the bulletin have been produced. BRATS has not presented any significant limitation that would compromise generalizations of its results within the Brazilian context. The initial impact of the bulletin, however, has been small, which may be due to its exclusively electronic dissemination format and technical language. We found nine publications citing BRATS in Google Scholar. CONCLUSIONS: It is hoped that the bulletin will promote the continuity of HTA actions among health-sector managers and professionals in Brazil.

The expression of vulnerability through infant mortality in the municipality of Embu.

CONTEXT AND OBJECTIVE: Infant mortality expresses a set of living, working and healthcare access conditions and opens up possibilities for adopting interventions to expand equity in healthcare. This study aimed to investigate vulnerability and the consequent differences in access to health services and occurrences of deaths among infants under one year of age in the municipality of Embu. DESIGN AND SETTING: This was a descriptive study in the municipality of Embu. METHODS: Primary data were collected through interviews with the families of children living in the municipality of Embu who died in the years 1996 and 1997 before reaching one year of age. Secondary data were obtained from death certificates. The variables collected related to living conditions, income, occupation, prenatal care, delivery and the healthcare provided for children. These data were compared with the results obtained from a study carried out in 1996. RESULTS: Statistically significant differences were found with regard to income, working without a formal employment contract and access to private health plans among the families of the children who died. There were also differences in access to and quality of prenatal care, frequency of low birth weight and neonatal inter-ocurrences. CONCLUSIONS: The employment/unemployment situation was decisive in determining the degree of family stability and vulnerability to the occurrence of infant deaths, in addition to the conditions of access to and quality of healthcare services.

[Prevalence and factors associated with iron deficiency in infants treated at a primary care center in Belém, Pará, Brazil]. / Prevalência e fatores associados à deficiência de ferro em lactentes atendidos em um centro de saúde-escola em Belém, Pará, Brasil.

The objective was to verify the occurrence of iron deficiency and associated factors in infants. This cross-sectional study included 365 infants (defined here as 6-24 months of age) treated at a primary care center in Belém, Pará, Brazil. Iron-deficiency anemia (hemoglobin < 11 g/dl and ferritin < 12 microg/l) was diagnosed in 55.1% of the sample, depletion of body iron reserves (hemoglobin < 11 g/dl and ferritin < 12 microg/l) in 15.3%, and iron sufficiency (hemoglobin < 11 g/dl and ferritin < 12 microg/l) in 18.1%. The results of the logistic regression model showed associations between iron deficiency (ferritin < 12 microg/l) and: 6-12 month age group, OR (odds ratio) = 3.67 and 95% CI: 1.93-7.04; non-utilization of iron-fortified formula as the first milk used after interrupting breastfeeding, OR = 1.93 and 95%CI: 1.04-3.60; and per capita income < or = 1 minimum wage, OR = 2.69 and 95%CI: 1.30-5.59. The occurrence of iron deficiency was high, showing the need to adopt effective measures to prevent this important public health problem.

[Prenatal and childbirth care equity in an area in Greater Metropolitan São Paulo, 1996]. / Eqüidade na atenção pré-natal e ao parto em área da Região Metropolitana de São Paulo, 1996.

A cross-sectional study was conducted to evaluate prenatal and childbirth care interviewing mothers of infants in the municipality of Embu (Greater Metropolitan São Paulo) in 1996, according to four socioeconomic strata. A door-to-door survey included a probabilistic sample consisting of 483 infants. In all strata more than 90% of the mothers had received prenatal care, but with late access in stratum 4 (residents of favelas, or slums). Breast examination during prenatal care, reported by only 60.8% of the mothers, was the worst single indicator of quality of prenatal care in the municipality. The outcome indicator - first prenatal consultation after the first trimester and total number of consultations less than six - was associated with maternal age (less than 20 years), low per capita family income (less than one minimum wage), and lack of private health plan. As for deliveries, 97.7% occurred in hospital, of which 32.5% by cesarean section, with the latter more frequent in private health care facilities (63.2%). No population segments were identified as being excluded from the health care system, but some indicators suggest greater deficiencies in socioeconomic stratum 4. These results have supported local health system managers in redefining health measures for the municipality.
