Our study analyzed temporal and demographic patterns of non-Hodgkin's lymphoma (NHL) incidence in Pennsylvania and compared Pennsylvania time trends with national trends. Joinpoint and age-period-cohort analyses summarized sex- and race-specific NHL incidence time trends between 1985 and 2004. Ecologic analysis identified demographic factors associated with age-adjusted county-specific NHL incidence. NHL incidence in Pennsylvania increased annually: 1.6% and 2.5% in white and black men and 1.6% and 3.2% in white and black women. National trends were similar, except for smaller increases in white men. Diffuse lymphoma appeared to be the major contributor to the increases. NHL incidence was higher in Pennsylvania counties with greater percentages of urban residents. NHL incidence patterns in Pennsylvania were parallel to those seen nationally, with the highest rates occurring in white men and in persons residing in urban areas.

    • "Accordingly, some studies have pointed to an association between NHL and living near to urban areas. They also noted that dioxins released by incinerators can be associated with lymphomas as demonstrated (Han et al., 2010; Liu et al., 2003). Exposure to ionizing radiation has also been suggested as a risk factor for NHL in some international studies as demonstrated (Karunanayake et al., 2008; Lacoste-Collin et al., 2007; McNally and Parker, 2006).

    ABSTRACT: INTRODUCTION: Brazil is one of the major pesticide consumers in the world. The continuous exposure to these substances may be etiologically associated with the development of Non-Hodgkin's Lymphoma (NHL). OBJECTIVE: Estimate the correlation between the per capita sales of pesticides in 1985 (exposure) and NHL mortality rates between 1996 and 2005 (outcome), by Brazilian micro-regions. METHOD: In this ecological descriptive study, the per capita consumption of pesticides in 1985 was used as a proxy of the population exposure to these chemicals in Brazil. All deaths by NHL occurred in the 446 non-urban micro-regions, between 1996 and 2005, among individuals with ages between 20 and 69, of both sexes, were retrieved from the Brazilian Mortality Information System. Micro-regions were then categorized into low, medium, high and very high pesticide consumption, according to the quartiles of per capita consumption of pesticides. NHL mortality rates and rate ratios for each quartile were obtained using the lowest quartile as reference. In addition, the Spearman's correlation coefficient between pesticide consumption and NHL mortality rates was estimated. RESULTS: A moderate correlation between per capita pesticides consumption and standardized mortality rate for NHL was observed (r=0.597). In addition, using the lowest quartile of pesticide consumption as a reference, the higher the quartile of pesticide consumption, the higher was NHL mortality risk: men - (second quartile - MRR=1.69, CI 95% 1.68-1.84; third quartile - MRR=2.41, CI 95% 2.27-2.57; fourth quartile - MRR=2.92, CI 95% 2.74-3.11) and females (second quartile - MRR=1.87, CI 95% 1.69-2.06; third quartile - MRR=2.28, IC 95% 2.10-2.47; fourth quartile - MRR=3.20; CI 95% 2.98-3.43). CONCLUSION: Our results suggest that pesticide exposure may play a role in the etiology of NHL.

    ABSTRACT: BACKGROUND: Macrosocial changes might affect mental health. We investigated whether the prevalence of common mental disorders (CMDs) changed over a 20-year period of industrialisation in Taiwan. METHODS: We used the 12-item Chinese Health Questionnaire to assess mental status of Taiwanese adults in 1990, 1995, 2000, 2005, and 2010. Respondents with scores of 3 or higher were classified as having probable CMDs. We assessed trends of probable CMDs with the Cochran-Armitage test and their risk factors (sex, age, marital status, educational level, employment status, and physical health) with multivariable logistic regression. The trends were compared with national rates of unemployment, divorce, and suicide. FINDINGS: Of 10 548 respondents, 9079 (86·1%) completed questionnaires. The prevalence of probable CMDs doubled from 11·5% in 1990 to 23·8% in 2010 (time trend p<0·001). Increases paralleled rises in national rates of unemployment, divorce, and suicide at all five timepoints. Significant risk factors for probable CMDs were female sex (adjusted odds ratio 1·6, 95% CI 1·4-1·8), 6 or fewer years of education (1·3, 1·1-1·5), unemployment (1·4, 1·1-1·7), and poor physical health that limited daily activities (6·5, 5·4-8·0). When we controlled for these factors in multivariable models, the time trends remained significant (p<0·0001). INTERPRETATION: National rates of unemployment, divorce, and suicide increased in parallel with prevalence of probable CMDs in Taiwan. Therefore, clinical and social preventive measures both seem important during times of change to the economy and labour market. FUNDING: Taiwan National Science Council.
