The ageing of the population - a time for action: the role of public health

The past two decades have witnessed the growth of the over-60,"elderly" population both in numbers and life expectancy. Similarly, there has been a shift in overall morbidity from acute to chronic causes and associated lifestyle factors. The increasing elderly population provides health care planners with new challenges at a time of decreasing resources. The public health approach, which equally stresses the responsibility of the individual, the family, the community and health care providers, is suggested as the starting point for addressing the issue.

Prevalence of exercise-induced asthma in schoolchildren in Kingston, St. Andrew and St. Catherine, Jamaica

A cross-sectional study was done, focusing on the prevalence of exercise-induced asthma in Jamaica and variables that may account for this rate. No previous study of this nature had been undertaken, and the investigators contend that there is a need to identify children who suffer from this condition but are unaware of it. A sample of 214 students from primary and secondary schools in the corporate area were chosen and given questionnaires to complete. Eighty-four of the children reported a history consistent with that of exercise-induced asthma and were further subjected to stress testing for a definitive diagnosis of this condition. A prevalence of 20.8 per cent [C.I ñ 5.35] was identified which reflected a rate comparable to that recorded in North America. There was a significantly higher prevalence in children of primary school ages, but all other variables considered for significance testing to determine associations between these and the prevalence of EIA proved not significant. A recomendation has been made for opportunity screening by medical practitioners
