Impact of a pilot acute respiratory infection (ARI) control programme in a rural community of the hill region of Nepal.

A prospective study was conducted to determine the magnitude of morbidity and mortality caused by acute respiratory infections (ARI) among children under 5 years of age and to assess the feasibility of reducing mortality owing to ARI by the use of community health workers. Villages selected for this study were situated on the south-west edge of Kathmandu Valley, about 24 km from the city centre. The study group consisted of 1019 children under the age of 5 years at the beginning of the study and followed for 3 years. During the 1st year, baseline information was collected. During the 2nd and 3rd years, intervention measures (health education, immunization and antibiotics for children with signs suggesting pneumonia) were taken and their effect assessed. There was a 59% reduction in the ARI-specific death rate among study children between surveillance year and intervention year I and a further 25% reduction in the ARI-specific death rate between intervention years I and II. Despite a substantial reduction in ARI mortality with the interventions, there was still an unacceptably high mortality from chronic diarrhoea, malnutrition and other factors. This implies that the programme to control ARI, diarrhoea, malnutrition and immunizable diseases should be integrated into one, within the framework of a primary health care strategy.

Epidemiological study of tobacco smoking behaviour among adults in a rural community of the hill region of Nepal with special reference to attitude and beliefs.

This study, designed to examine adult smoking behaviour, attitudes and norms was carried out in the hill villages of Alapot and Bhadrabas, Nepal, using the WHO standardized survey questionnaire. Some 1506 adults were interviewed. The overall prevalence of daily smokers is 73.7%. The majority of people, though aware of hazards of smoking, are not concerned with its possible effects on their own or other people's health. More males than females endorse public action against smoking. Both the endorsement of public action against smoking and awareness of social norms discouraging smoking increase with educational attainment. The motives for not smoking and endorsement of public actions against smoking have been ranked. Based on these findings strategies for a national smoking control programme have been recommended.

Domestic smoke pollution and respiratory function in rural Nepal.

A study was conducted to see the effect of domestic smoke pollution on respiratory function by using vitalograph Model 20.400 S-type dry portable spirometer in 150 randomly selected female subjects aged 30-44 years from a rural area situated in the outskirts of Kathmandu valley at an altitude of 4,800 ft. above sea level. The area is totally free from industrial and atmospheric pollution. Women spend considerable time near the fireplace, which serves both cooking and heating purposes and emits smoke from wood and other biomass fuel. Domestic smoke pollution is considerable because dwellings are ill-ventilated and without chimnies. The selected sample comprised of 6 groups-25 subjects each of 3 exposure levels to domestic smoke pollution amongst smokers and non-smokers. All the spirometric tests (FVO, FEV1 and FMEF 25-75) were performed in a standard way as recommended by American Thoracic Society in Snowbird Meeting in 1979. Variation of age, height, arm-span and weight between the three different levels of exposure to domestic smoke in both the smokers and non-smokers were compared and results revealed no significant variation in all the variables mentioned above. There was a fall of mean FVC, FEV1 and FMEF 25-75 as duration of exposure increased. This decline was found to be statistically significant amongst the smokers but not amongst the non-smokers. Similar results was found even after adjusting for age & height.
