RESUMO
Proportion of aged persons in India is increasing and is expected to be around 70 million by the end of the year 2000. The epidemiological consequences would be increase in the geriatric problems, particularly, impairments, disabilities and handicaps There are not many community-based studies using the International Classification of Impairments, Disabilities and Handicaps (ICIDH). The main objective of this study was to estimate the prevalence of disabled in the elderly population (aged above 60 years) in a district of south India using ICIDH classification. Thirty villages were selected using probability proportional to size linear systematic sampling (PPSLSS) from Villupuram health unit district in Tamilnadu in south India. One hundred and five households were selected from each selected village by using linear systematic sampling. A structured proforma was administered to 974 subjects to obtain information on disability as perceived by rural geriatric population. Visual disability was found to be the most important single preventable disability (56%). Only 33% of persons with visual disability wore spectacles. A decline in social interaction was reported. There was an urgent need to strengthen health care activities related to geriatric health care to improve the quality of life of the elderly population, including care of vision in particular.

OBJECTIVE: To adapt and develop a method for finding out what proportion of the variation among small areas in the number of births to married women is excess (systematic) variation over and above the chance (random) variation. METHODS: We adopted a two-stage sampling procedure to select 20 sub-centres in south India. We contacted all households and collected information on recent births and socioeconomic variables from all ever married women aged 15-49 years. Systematic and random components of variance were estimated using Poisson regression, adjusting for socioeconomic factors. RESULTS: Of the observed variance in fertility, 65% is explained by the estimated systematic variation. Though many important explanatory variables are considered, the systematic variance is significant mainly among illiterate women, those aged under 18 years at marriage, the marginalized population, and those with labourer husbands. CONCLUSIONS: Poisson regression can be adapted to estimate the random and systematic components of variation in fertility among small areas. The systematic component of variance can further be adjusted for socioeconomic factors. Identification of the significant predictors will help health planners develop necessary interventions at the small area level.

Data collected on 689 infants, in a study to assess the incidence of diarrhoea and acute respiratory infections during infancy, is used here to quantify the extent of under-reporting in diarrhoea morbidity surveys. The study area consisted of two contiguous primary health centres in Villupuram health unit district in Tamil Nadu, South India. Each day of infancy was assigned a recal period and proportion of diarrhoeal days for various recall period computed. The proportion of diarrhoea was 11.3%, 12.0% and 11.2% for zero, one and two days of recall period, respectively, after which the proportion decreased. The under-reporting of diarrhoea was approximately 15%, 26% and 45% with three, six and 7-13 days of recall period, respectively. As there is considerable under-reporting of diarrhoea morbidity when recall period exceeds three days, it would be best to collect information on diarrhoea at least twice a week in diarrhoeal morbidity surveys.

Data collected on 689 infants, in a study to assess the incidence of diarrhoea during infancy, is used here to quantify the extent of under-reporting in diarrhoea morbidity surveys. The study area consisted of two contiguous primary health centres in Villupuram health unit district in Tamil Nadu, south India. Each day of infancy was assigned a recall period and proportion of diarrhoeal days for various recall period computed. The proportion of diarrhoea was 11.3%, 12.0% and 11.2% for zero, one and two days of recall period, respectively, (mean 11.5%) after which the proportion decreased. The under-reporting of diarrhoea was approximately 15%, 26% and 45% with three, six and 7-13 days of recall period, respectively compared to mean. As there is considerable under-reporting of diarrhoea morbidity when recall period exceeds three days, it would be better to collect information on diarrhoea twice a week in diarrhoeal morbidity surveys.
PIP: Diarrhea morbidity is an indicator commonly used to assess the health status of young children and to measure the impact of a number of health-related interventions. In longitudinal studies, information is usually collected orally anywhere from daily to every few weeks. However, as the recall period lengthens, the likelihood increases that episodes of diarrhea will be forgotten and subsequently not reported, leading to overall underestimates of diarrhea incidence. Data collected on 689 infants in a 1991-93 study of vitamin A supplementation in mothers and infants were used to quantify the extent of under-reporting in diarrhea morbidity surveys in 2 contiguous primary health centers in Villupuram health unit district in Tamil Nadu, India. Each day of infancy was assigned a recall period and proportion of diarrheal days for the various recall period computed. The proportion of diarrhea was 11.3%, 12.0%, and 11.2% for 0, 1, and 2 days of recall period, respectively, after which the proportion decreased. The under-reporting of diarrhea was approximately 15%, 26%, and 45% with 3, 6, and 7-13 days of recall, respectively, compared to the mean. Given the high degree of under-reporting of diarrhea morbidity when the recall period exceeds 3 days, it is better to collect data on diarrhea twice a week in diarrheal morbidity surveys.

OBJECTIVES: To assess the impact of Vitamin A supplementation to the mother soon after delivery and to the infant at six months on morbidity in infancy. DESIGN: Randomized double blind placebo controlled field trial. SETTING: 51 villages in two contiguous Primary Health Centers in Villupuram Health Unit District of Tamil Nadu, South India. SUBJECTS: 909 newly delivered mother-and-infant pairs. INTERVENTIONS: Both mother and infant received Vitamin A (300,000 IU for mothers and 200,000 IU for children) in 311 instances (AA); mother received Vitamin A but infant received Placebo in 301 instances (AP); and both mother and infant received Placebo in the remaining 297 instances (PP). MAIN OUTCOME MEASURES: Incidence of diarrhea and Acute Respiratory Infection (ARI); distributions of infants by frequency of episodes and number of infected days. RESULTS: 233 in the AA Group and 228 each in the AP and PP Groups were followed up regularly. The incidence of diarrhea in these infants was 97.4%, 96.9% and 94.7% in the three groups, mean number of diarrheal episodes was 4.4, 4.6 and 4.2 and median number of days in infancy with diarrhea was 26, 26 and 22 days, respectively. For ARI, the incidences were 96.6%, 95.6% and 96.1%, means were 4.8, 5.1 and 4.8 episodes, and the medians were 32, 34 and 34 days, respectively. CONCLUSIONS: Prophylactic administration of mega doses of Vitamin A to the mother soon after delivery and to the infant at six months do not have any beneficial impact on the incidence of diarrhea and ARI in infancy.
