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.

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.

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.
