“…This relationship was first described in detail by Farooq et al, (1966) in Egypt and since then by studies in different endemic areas (Rosenfield, 1990;Yi-Xin and Manderson, 2005). In Brazil, the role of socioeconomic factors in Schistosoma mansoni transmission has been examined by studies in rural areas (Coura-Filho et al 1994;Lima e Costa, 1991;Silva et al, 1997) and urban (Barreto,1991 ;Kloetzel, 1989;Lima e Costa et al, 1987;Ximenes et al, 2003). However, only Ximenes et al (2003) studied the relationship between socioeconomic determinants and schistosomiasis distribution in depth, using noncausal determinism, which posits that socioeconomic conditions determine and operate through various conditioning factors, or intermediate mechanisms, not necessarily in a causal manner.…”

“…The second set characterizes its consumption patterns. This information, which is important in determining the position of the family and individuals in the production process (Ximenes et al, 2003), was related primarily to the head of the household. Considering the conceptualization of the household as a social and residential unit (Berman et al 1994) and our previous studies in another rural area in Minas Gerais (Bethony et al, 2004), we assumed that all study members in a given household belonged to the same socioeconomic group as the household head due to the fact that they share in the production and consumption process.…”

They found a strong relationship between socioeconomic variables and schistosomiasis in a town in northeast Brazil, but their findings are not applicable to rural areas, where the generally weaker socioeconomic differentiation and more widespread schistosomiasis risk present a different epidemiological setting.…”

“…The hypothesis of this study is that the distribution of schistosomiasis in the Virgem das Graças population is determined by socioeconomic factors rather than occurring at random. Due to the high degree of household aggregation of schistosomiasis reported by Bethony et al (2001) from a nearby rural study area and by Ximenes et al (2003) in a town in northeastern Brazil, the role the household as a social organization and in economic decision making (Berman et al, 1994;Kroeger, 1985), particular emphasis in this study was given to the household level.…”

The objective of this paper is to identify and quantify socioeconomic determinants of S. mansoni infection in the rural area of Virgem das Graças in Minas Gerais State of Brazil. A cross-sectional study was carried out to examine the prevalence and intensity of schistosomiasis in relation to socioeconomic characteristics of the households. Log-binomial regression analysis was used to examine the data on both the household and individual levels, analyzing the prevalence ratios for the association of schistosomiasis and socioeconomic variables related to the head of the household. Multiple comparisons through mixed effect modeling were used to examine the relationship between intensity of infection (geometric mean egg counts) and different levels of socioeconomic variables, respectively. In the univariate analysis, place of residence, number of persons per room, and lack of motorized transport were associated with schistosomiasis at the household level and age and unsafe water contact at the individual level. Age, unsafe water contact, number of persons per room, household possessions and lack of education of head of household remained significant predictors of schistosomiasis in the multivariable analysis. Only age was significantly associated with intensity of infection of individuals. It is concluded that widespread poverty, the rural environment, and weak socioeconomic differentiation that result in intense contact with infective water appear to minimize the protective effect of piped water supply and other socioeconomic parameters on schistosomiasis found in other studies. The potential role of socioeconomic development in conjunction with schistosomiasis control is described and areas for further studies are identified.

“…Groups with low socioeconomic status generally have a higher risk of contracting schistosomiasis and of being affected by the disease for an extended period of time. This risk is related to a variety of factors that include a lack of access to safe water and to health services (Ximenes et al 2003, Kloos et al 2008, Watts 2008. Population movements affect all areas and communities that are vulnerable to schistosomiasis in Brazil.…”

Schistosomiasis remains a global public health problem affecting about 240 million people. In Zambia, 2 million are infected while 3 million live with the risk of getting infected. Research and interventions relating to schistosomiasis are mainly linked to disease epidemiology. Malacological and ecological aspects of the disease are superficially understood. Developing effective control measures requires an understanding of interacting environmental and socioeconomic factors of host snails vis-a-vis schistosomiasis. Therefore, the present work involved collecting social and environmental data in a large field study in two zones in Zambia that are different in terms of temperature and rainfall amounts. Social data collected through questionnaires included demographic, educational and knowledge of schistosomiasis disease dynamics. Environmental data included physicochemical factors, aquatic plants and snails. Gender (P < 0.001) significantly influences livelihood strategies, while age (P = 0.069) and level of education (P = 0.086) have a moderate influence in zone I. In zone III, none of these factors (age, P = 0.378; gender, P = 0.311; education, P = 0.553) play a significant role. Environmental parameters explained 43 and 41 % variation in species composition for zones I and III, respectively. Most respondents’ (52 %, 87 %) perception is that there are more cases of bilharzia in hot season than in other seasons (rainy season 23 %, 7 %; cold season 8 %, 0 % and year round 17 %, 6 %) for zone I and zone III, respectively.Electronic supplementary materialThe online version of this article (doi:10.1007/s10661-016-5351-y) contains supplementary material, which is available to authorized users.
