Postnatal depression in Southern Brazil: prevalence and its demographic and socioeconomic determinants

<p>Abstract</p> <p>Background</p> <p>Studies investigating the prevalence of postnatal depression (PND) show rates ranging from 5% to 36.7%. The investigation of age, race, educational levels, religion and income as risk factors for PND has yielded conflicting results. The aim of this study is to investigate the prevalence of PND in women residing in Southern Brazil and the associated risk factors.</p> <p>Methods</p> <p>This is population-based cross-sectional study of women residing in Porto Alegre who delivered in June 2001. A sample of 271 participants were selected from the Record of Living Newborn Infants of the State Health Department (the official Brazilian database and stores the name and address of all women who give birth to living newborn infants) using a process based on pseudo-random numbers which choose a random sample from 2.000 records. Once the addresses were identified, the women were visited at their place of residence (home, hotel, boarding house and prison), with the interviews taking place between the 6^thand the 8^thweek after delivery.</p> <p>The association between the risk factors and PND was investigated through bivariate analysis using Pearson's chi-square test. Student's t-test was used to analyze the continuous variables. To identify independent risk factors, multivariate analysis was performed using hierarchical levels with a predefined model that took into account the time relationship between PND and the risk factors. Cox's regression was used to calculate the prevalence ratios.</p> <p>Results</p> <p>The PND prevalence rate found was 20.7% (CI 95% 15.7 – 25.7). After adjusting for confounding variables, per capita income was found to have a significant association with PND.</p> <p>Conclusion</p> <p>The prevalence of PND is higher than the figures found in most developed countries and similar to the figures found in developing countries. Differences in PND by regions or countries can be partially explained by the effect of income on the mediation of risk factors. In low income populations, women should be routinely evaluated for postnatal depression, and those with no partner or spouse are likely to require further care from health services and should be given the benefit of mental health prevention programs.</p

Traces of places: sacred sites in miniature on Minoan gold rings.

Sacred sites in Minoan Crete are known from both archaeological remains and iconography. Glyptic art is the most extensive body of Aegean Bronze Age representational art and consists of carved seals in the form of engraved metal signet rings, stone seals, and the clay impressions (sealings) that these were used to produce. Gold signet rings from the Cretan Neopalatial period (1750–1490 BCE) depict various types of sacred site including mountain, rural, cave, and urban sanctuaries. How should we understand the built structures depicted in these miniature cult scenes? Do they all depict variations of walls or buildings, or are they altars? This paper differentiates the built structures depicted in cult scenes on Minoan gold rings, correlates them to archaeological remains at Minoan sacred sites, and proposes an explanation of ephemeral cult structures now only recorded in the iconographic evidence. It will be demonstrated that these miniature art forms represent Minoan sacred sites in three ways: as natural places characterised by the presence of trees and stones and the absence of architecture; as outdoor sanctuaries surrounded by ashlar stone walls; and as shrines and altars, the shapes of which evoke natural cult locations such as mountains and sacred groves through abstract form. It will be argued that representation of Minoan cult structures that evoked the natural landscape within prestigious art forms was a method whereby Neopalatial elites naturalised their authority by depicting themselves in special relationship with the animate landscape
