arrow Health Care of the Rural Aged Books

The second sub-sample survey covered 843 subjects aged 60 + (Male 305, Female 538). The main objectives of this sub-sample survey were to assess the impact of the Geriatric Clinic on the aged population in the catchment area and the effects of the intervention measures (comprising medical, psychological, social, economic, educational, nutritional and other aspects) upon them. The survey lasted from 1st May 1987 to 31st July 1987.

Sampling procedure

Twenty-seven villages were selected at random falling within the geographical area of the 17 sub-centres. Care was taken to enlist a minimum of 41 subjects from each of the sub-centre so that no sub-centre was under-represented. In cases of failure to achieve this minimum target from the selected village, another village from the same sub-centre was selected at random for collection of sample. There was an overlap among the subjects in the sense that 395 subjects (Group I) (Male 128, Female 267) were already registered in the Geriatric Clinic as a part of the main study, while the other 448 subjects (Group II) (Male 177, Female 271) had no prior contact with the project staff. Two separate proformae (Appendix VIII) were evolved for each of these groups. The Group II subjects were also administered the main study proforma. The data was collected through house visits by the project staff. The details of the data collected and conclusions are offered below in brief.

Data on Group II subjects (N = 448)

1. The rank order of the symptoms encountered in these subjects on screening schedule were as follows :

Visual handicap (N = 274, 61%), pain in the joints (N = 151, 34%), vague bodily pain (N = 66, 15%), giddiness (N = 65, 15%); cough (N = 43, 10%), itching (N = 39, 9%), sleeplessness (N = 37, 8%), expectoration/haemoptysis (N = 29, 7%) and hearing deficit (N = 28, 6%). As many as 85 persons (19%) failed to score on any items on the screening schedule. The complaints from Group II subjects (N = 448) on the screening schedule were fewer in number (an average of 2 per patient) than among those (N = 1910) who attended the geriatric clinic (an average of 6 per patient).

2. The system-wise classification and comparison between Group II subjects and main study subjects is as follows (Table 14).

The important features of the psychiatric complaints formed only 1.1% in contrast to 8.4% in the study group. While in the study group there were only 3 subjects with 'no medical diagnoses', 87 (19.4%) in the sub-sample survey (Group II) carried 'no medical diagnoses'.

3. There was a greater representation from the higher socio-economic status in the sub-sample survey than the study group.

4. Lesser number (11.6%) were found to be living alone in the sub-sample survey data than in the study group (25.5%).
