The author assesses the patterns of family extension in Peru by examining variations in family composition over the family life cycle. The amount and type of extension among Peruvian families at successive stages of family development are examined. The relative importance of general overlap and of child and spouse replacement mechanisms as processes that help to ensure the viability of residential family units is studied. The empirical analysis is based on a 1970-1971 survey of a national sample of Peruvian households 相似文献

A survey of perceived morbidity was carried out in rural population in eight villages and four wards of Saoner town, covering a total population of 8,876. The nature of illness was assessed by weekly visits to the families. History regarding treatment taken for disease and its source was taken. The overall incidence of perceived morbidity was 176.35 spells of sickness per 1000 population per month. Health care agency was contacted for 36.7 per cent spells of sickness. Utilisation of health services was found to be affected significantly by factors like age (chi 2 = 138.36), literacy (chi 2 = 14.123), type of occupation (chi 2 = 433.74), nature of illness (chi 2 = 83.578) and accessibility of health services. A health behaviour model of the population has also been discussed in this paper. 相似文献
