RESUMEN
Background. Alcohol use is common in many cultures. Excessive use of alcohol adversely impacts individuals, families and communities. Medicine, which uses biomedical models and perspectives, views alcohol dependence as a disease. Alcohol use and dependence are complex societal problems, which need to be viewed through multidisciplinary approaches and corrected by adopting intersectoral efforts involving local communities. Methods. We used qualitative methods such as focus group discussions and in-depth interviews to document perspectives on alcohol use among a tribal community in southern India. We recorded traditional norms, changing patterns of use of alcohol and its consequences for individuals, families and the community. Results. Eight focus group discussions and eleven in-depth interviews were conducted. Though consumption of alcohol is part of the local culture, changes in occupation and availability of alcohol has made its consumption a problem. The introduction and easy availability of Indian-made foreign liquor, which is stronger than the locally brewed variety, in government-run outlets has changed the culture of drinking at festivals to drinking more often. This leads to public fights, domestic violence and increasing mortality and morbidity due to road traffic incidents and ill health. The age of initiation into drinking has decreased. Conclusion. The introduction of non-traditional and commercial alcohol use has put a heavy price on tribal and rural people. Community-based interventions targeting young children and adolescents may pay more dividends than pursuing purely medical treatments for problem drinkers.
RESUMEN
Background & objectives: Soil-transmitted helminths (STH) are a major public health problem in tropical and sub-tropical countries, affecting the physical growth and cognitive development in school-age children. This study was aimed to assess the prevalence and risk factors of STH infection among school children aged 6 -14 yr in Vellore and Thiruvanamalai districts in south India. Methods: Children aged 6-14 yr, going to government and government aided schools (n=33, randomly selected) in Vellore and Thiruvanamalai districts were screened to estimate the prevalence of STH, and a case control study was done on a subset to assess the risk factors for the infection. Results: The prevalence of STH was 7.8 per cent, varying widely in schools from 0 to 20.4 per cent, in 3706 screened children. Hookworm (8.4%) rates were high in rural areas, while Ascaris (3.3%) and Trichuris (2.2%) were more prevalent among urban children. Consumption of deworming tablets (OR=0.25, P<0.01) offered protection, while residing in a field hut (OR=6.73, P=0.02) and unhygienic practices like open air defaecation (OR=5.37, P<0.01), keeping untrimmed nails (OR=2.53, P=0.01) or eating food fallen on the ground (OR=2.52, P=0.01) were important risk factors for STH infection. Interpretation & conclusions: Our study indicated that school children with specific risk factors in the studied area were vulnerable subpopulation with elevated risk of STH infection. Identifying risk factors and dynamics of transmission in vulnerable groups can help to plan for effective prevention strategies.
