Environmental pesticide exposure as a risk factor for Alzheimer's disease: a case-control study.

The aim of this study was to evaluate the influence of pesticide exposure on the development of Alzheimer's disease (AD), taking into account the potentially confounding factors (genetic, occupational exposure, and sociodemographic). The 1924 study participants (>70 years old) were randomly selected in the Saguenay-Lac Saint-Jean region (Quebec, Canada). The AD diagnosis was established in three steps according to recognized criteria. Sixty-eight cases were paired with a nondemented control for age (+/-2 years) and sex. Structured questionnaires addressed to subjects and proxy respondents allowed a description of the sociodemographic characteristics, lifestyle characteristics, and residential, occupational, familial, and medical histories. Assessment of environmental exposure to pesticides was based on residential histories and the agriculture census histories of Statistics Canada (1971-1991) for herbicide and insecticide spraying in the area. Statistical analyses were performed with a logistic regression, adjusting for potential confounding factors. The results failed to show a significant risk of AD with an exposure to herbicides, insecticides, and pesticides. However, future investigations are needed to establish more precisely the identification, measurement, mobility, and bioavailability of neurotoxic pesticide residues in relation to AD.

Sam Greenhouse's years at the Census Bureau and the UNRRA.

Sam Greenhouse joined the Census Bureau as a clerk at an interesting time period for the agency. The first use of sampling in the decennial census occurred in 1940. There was a major expansion of the amount of data collected. The organization of the Census Bureau underwent radical changes, including the growth of the Population Division of which Greenhouse was a part, and the Office of Statistical Assistant was established. After the 1940 census Greenhouse was also part of a new intercensal program which became the forerunner of today's Current Population Survey, and was on hand for the transition of the physical location of the agency from Washington D.C. to Suitland, Maryland. After America's entry into World War II, Sam Greenhouse left the Census Bureau and worked with the United Nations Relief and Rehabilitation Administration (UNRRA), designed to manage the support and eventual repatriation of refugees who would come under Allied control at the war's end.

Nineteenth century Indian leper censuses and the doctors.

This study describes the circumstances under which enumerations of "lepers" were conducted in India in the late 19th century, and the ideological biases of the respective investigators and the meanings that they read into the statistics. This report focuses on the Bombay Presidency leprosy returns of 1867, examined in 1871 by Henry Vandyke Carter, and the decennial nation-wide population census of 1871-1872, 1881, and 1891, in which the leprosy-affected, among other infirm persons, were also enumerated. The evidence examined includes the investigators' reports and other published and unpublished contemporaneous documents. These censuses were undertaken at a time when the etiology of leprosy was a major controversy, but the evidence here indicates that the efforts to clarify the etiology and estimate the virulence of the disease in India by means of statistics were animated by the desire to justify and embellish pre-conceptions. Despite the claim that they were necessary for leprosy control, the censuses, for various reasons, were not utilized towards that end in India.

Mapping and analysing 200 years of the census.

"The 10th of March 2001 will mark the two-hundredth anniversary of the first census of population and should be an opportunity to look back not merely at the history of census-gathering but at the development of the population, economy and society of the British Isles. [We describe] a major university-based project led by ourselves and funded by the Economic and Social Research Council, the Leverhulme Trust and other bodies.... The project is supported by ONS [Office for National Statistics] and one of our central goals is to create an historical social atlas for publication at the bi-centenary."
