    This surveillance report examines changes from 1989–1992 to 2008–2010 in preterm and small-for-gestational-age birth rates in Québec for the general population and by mother’s first language. Rates based on selected sociodemographic characteristics (e.g., place of residence, material deprivation, and immigrant status) of mothers in each linguistic community are also presented.

    The report’s main finding is that previously observed variations in perinatal health favoring Anglophones were not observed in 2008–2010: preterm and small-for-gestational-age birth rates were similar for Anglophones, Francophones, and Allophones during this period.

    Preterm birth rates

    • Preterm birth rates increased for all linguistic communities from 1989–19921 and stabilized beginning in 2002–2004.
    • In 2008–2010 preterm birth rates per 100 live births were comparable for Francophones, Anglophones, and...

    • This report is based on an analysis of scientific articles published in peer-reviewed journals and on expert reports by recognized national and international health organizations.
    • Sources of exposure to radiofrequency electromagnetic fields (RF-EMFs) are varied and increasingly prevalent.
    • Public exposure to RF-EMFs comes from two types of sources:
      • Local (near-field) sources
        These are sources to which people are exposed at very short distances, namely less than a few centimetres from the body. Cell phones and cordless phones are two examples. Exposure from local sources can be close to the limits established under existing standards.
      • Environmental sources
        These are sources to which the body is exposed at greater distances. They include microwave ovens, wireless Internet routers, smart meters, and radio, TV, and cell phone antennas. Exposure from environmental sources is generally much lower than established exposure limits...

    A lot of new data on the immunogenicity, efficacy and effectiveness of fewer than three doses of HPV vaccine have become available since the publication of the CIQ report on the 2012 knowledge update. The two-dose schedule has become a standard that is widely accepted around the world. Such schedules are currently in use in more than half (48/82) of the countries offering HPV vaccination programs. The same schedule has been approved and recommended by the World Health Organization (W HO) and the Global Alliance for Vaccines and Immunization (GAVI).

    A number of clinical and ecological studies have even come up with some interesting and promising results in terms of the immunogenicity and efficacy of single-dose HPV vaccination. Immunogenicity studies have shown that sero-conversion rates after a single dose of vaccine are often in excess of 95%, although with considerably lower geometric mean titers (GMTs) than those observed after two or three doses. However, antibody...
