The role of salt abuse on risk for hypercalciuria

Background: Elevated sodium excretion in urine resulting from excessive sodium intake can lead to hypercalciuria and contribute to the formation of urinary stones. The aim of this study was to evaluate salt intake in patients with urinary lithiasis and idiopathic hypercalciuria (IH).Methods: Between August 2007 and June 2008, 105 lithiasic patients were distributed into 2 groups: Group 1 (n = 55): patients with IH (urinary calcium excretion > 250 mg in women and 300 mg in men with normal serum calcium); Group 2 (n = 50): normocalciuric patients (NC). Inclusion criteria were: age over 18 years, normal renal function (creatinine clearance >= 60 ml/min), absent proteinuria and negative urinary culture. Pregnant women, patients with intestinal pathologies, chronic diarrhea or using corticoids were excluded. The protocol of metabolic investigation was based on non-consecutive collection of two 24-hour samples for dosages of: calcium, sodium, uric acid, citrate, oxalate, magnesium and urinary volume. Food intake was evaluated by the three-day dietary record quantitative method, and the Body Mass Index (BMI) was calculated and classified according to the World Health Organization (WHO). Sodium intake was evaluated based on 24-hour urinary sodium excretion.Results: The distribution in both groups as regards mean age (42.11 +/- 10.61 vs. 46.14 +/- 11.52), weight (77.14 +/- 16.03 vs. 75.99 +/- 15.80), height (1.64 +/- 0.10 vs. 1.64 +/- plusorminus 0.08) and BMI (28.78 +/- 5.81 vs. 28.07 +/- 5.27) was homogeneous. Urinary excretion of calcium (433.33 +/- 141.92 vs. 188.93 +/- 53.09), sodium (280.08 +/- 100.94 vs. 200.44.93 +/- 65.81), uric acid (880.63 +/- 281.50 vs. 646.74 +/- 182.76) and magnesium (88.78 +/- 37.53 vs. 64.34 +/- 31.84) was significantly higher in the IH group (p < 0.05). There was no statistical difference in calcium intake between the groups, and there was significantly higher salt intake in patients with IH than in NC.Conclusions: This study showed that salt intake was higher in patients with IH as compared to NC.

Anti-poverty policies in Brazil: Reviewing the past ten years

This article reviews the main anti-poverty policies implemented in Brazil from the early 1990s to the early 2000s. These include focused and universal policies - such as education and health care - as well as the rural development, a 'middle ground' policy. Though the inter-municipal consortium, a new institutional arrangement gathering municipalities together, has emerged as a promising policy implementation tool, anti-poverty policies have faced implementation difficulties. Lack of coordination between different programs, even within the same policy area, has impaired their effectiveness. As a consequence, compensatory programs, based on monetary transfers to poor families, which face fewer implementation problems, have become the dominant type of anti-poverty policies in Brazil. Despite these shortcomings, a small Brazilian state, Santa Catarina, was able to reduce by 46 percent the number of individuals living in poverty in just ten years. This is a sign that fighting poverty can, after all, be a feasible endeavor. © 2004 IIAS, SAGE Publications (London, Thousand Oaks, CA and New Delhi).

Sexual abuse and alcohol use among women in metropolitan Sao Paulo, Brazil: a general population study

OBJECTIVE:The present study aimed at estimating the prevalence of lifetime sexual abuse among women and at investigating its association with alcohol consumption.METHOD:Population-based survey conducted through a representative and stratified cluster sample of metropolitan São Paulo. GENACIS questionnaire was used. Sample unit was the home, and all residents aged 18 years and over were interviewed. The outcome was lifetime sexual abuse. The univariate statistical analysis used the Rao-Scott test. Logistic regression was used for the multivariate analysis.RESULTS:The final sample totalized 1,216 women aged 18 years and over; the response rate was 75.0%. Most women were married (56.6%) and had less than 12 years of formal education (59.0%); 46.2% were aged between 25 and 44 years, and 44.4% had a low income. Of the respondents, 7.5% reported having suffered lifetime sexual abuse. Multiple logistic regression model showed an association between lifetime sexual abuse and being a heavy drinker (OR = 4.97) and being a former drinker (OR = 2.04).CONCLUSIONS:There are few population studies in Brazil investigating sexual abuse and its relation to alcohol use. Although the prevalence of lifetime sexual abuse in the present study was smaller than that observed in other studies, it is a highly expressive percentage on account of its social and economic impact, as well as its potential effect on the health system.
