“…26 A narrow age gap between a child and a next-older-sibling with MTI was a risk factor for TB both among children with a known TB contact and those without. This finding has been documented in studies of other infectious agents 27,28 but not, to our knowledge, in studies on MTI. Traditionally, children with active TB disease are not considered infectious because they excrete few bacteria.…”

“…H. pylori infection was generally thought to be related to socioeconomic status, but the results from different groups have been contradictory. Koch et al (2005) showed that age of the examined participants was associated with H. pylori seropositivity. Huang et al (2004) found no differences in age, sex, and socioeconomic/domestic variables between antigenpositive and antigen-negative subjects among the Penan.…”

Background: Helicobacter pylori infection leads to many upper gastrointestinal diseases. Migrant workers are the main part of floating population in China. However, up to now, their health status has not been a focus of attention. Methods: In order to assess the status of H. pylori infection among migrant workers in Shijiazhuang, over five years we interviewed 324 individuals between 2007 and 2011. Each underwent a rapid urease test to identify H. pylori infection and socio-demographic indicators were collected using a survey questionnaire. Results: Our results showed that family income (P = 0.003), dietetic hygiene (P = 0.005), education (P = 0.004) and marital status (P = 0.007) were associated with H. pylori infection. Conclusion: We found that migrant workers had little basic knowledge of H. pylori and their prevalence of infection remains high. Therefore, we need to promote education and awareness of H. pylori and to ensure access to diagnosis and treatment for infected workers.

“…The association between stomach cancer and family size was not different in strata of age, sex, period and socioeconomic status. Helicobacter pylori is the strongest determinant of gastric cancer development, and an early acquisition of infection has been reported to be directly associated with domestic crowding and sibship size (Mendall et al, 1992;Webb et al, 1994;Blaser et al, 1995;Koch et al, 2005). Stomach cancer has been associated with low socioeconomic status and unfavourable living conditions, such as childhood deprivation (Logan, 1982;Howson et al, 1986).…”

We analysed the effects of number of siblings on the risk of solid tumours using the Swedish Family-Cancer Database, including population-based information on over 11 million individuals and more than 178 000 cancer patients diagnosed between 1958 and 2004. Incidence rate ratios (RRs), estimated by Poisson regression models, were adjusted for age, sex, birth cohort, area of residence and socioeconomic status. Having eight or more siblings vs none increased the risk of stomach cancer (RR ¼ 1.83, 95% confidence interval (CI), 1.44 -2.34). Anal cancer diagnosed before age 40 showed the strongest association with the total siblings (RR ¼ 3.27, 95% CI, 2.04 -5.26 for five or more siblings vs none). Endometrial (RR ¼ 0.76, 95% CI, 0.70 -0.82), testicular (RR ¼ 0.71, 95% CI, 0.62 -0.82), skin cancer (RR ¼ 0.82, 95% CI, 0.69 -0.97) and melanoma (RR ¼ 0.72, 95% CI, 0.65 -0.79) showed strong decreased risks for five or more siblings vs none. Prostate cancer risk for those with five or more older siblings vs none was 1.38 (95% CI, 1.23 -1.55). Having five or more younger siblings was most strongly associated with stomach cancer (RR ¼ 1.59, 95% CI, 1.29 -1.95) and melanoma (RR ¼ 0.68, 95% CI, 0.59 -0.79). We conclude that sibship characteristics are strong correlates of cancer risk at several sites; plausible interpretations include socioeconomic status.

Seroprevalence and Risk Factors for Helicobacter pylori Infection in Greenlanders

Abstract: The age-specific prevalence pattern in Greenland is intermediate between that of developing and developed countries. The risk factor pattern indicates crowding and older siblings in particular to be key elements in risk of infection.
