Recent trends in the prevalence and severity of childhood asthma.

OBJECTIVE: To examine changes in the prevalence and distribution of childhood asthma and its relationship with various measures of children's health and functioning between 1981 and 1988. It was hypothesized that there would be an increase in the prevalence of asthma, especially among black children, and that available measures would suggest a deterioration in the health and functioning of children with asthma over this period. DESIGN: Analyses of data from the Child Health Supplements to the National Health Interview Survey. SETTING AND SAMPLE: Nationally representative random sample of 15,224 children aged 0 to 17 years in 1981 and 17,110 in 1988. MAIN OUTCOME MEASURES: Changes in (1) the prevalence and distribution of asthma, and (2) among children with asthma, the percentage of children hospitalized, days spent in bed, school days lost in the year prior to survey, and parent ratings and reports of children's overall health status and behavior problems. RESULTS: The estimated prevalence of childhood asthma increased from 3.1% in 1981 to 4.3% in 1988 (P < .0001), with similar increases for children, adolescents, and both sexes. Increases occurred among white children (2.7% to 4.1%; P < .0001) but not black children (5.3% vs 5.1%; not significant). Among those with asthma in 1988 compared with 1981, there was better overall health status (11% vs 24% fair/poor; P < .0001) and fewer with 30 or more days spent in bed in the last year (3.9% vs 7.2%; P < .04). We also observed trends toward a lower rate of hospitalization in the last year (10% vs 14%; P = .07), fewer school days missed (2% vs 6% with > 30 days; P = .08), and a lower rate of extreme behavior problem scores (13% vs 18%; P = .09) in 1988 compared with 1981. Reductions were similar among both black and white children. CONCLUSIONS: These results indicate that the estimated prevalence of asthma among children in the United States increased by almost 40%, and that although the increase occurred exclusively among white children, the prevalence of asthma still remains higher in black children than in white children. There was no support for increasing asthma severity and functional impact among either black or white children with asthma in 1988 compared with 1981. These findings provide no evidence to support the beliefs that asthma prevalence is increasing largely among black children or that the severity of asthma among most children in the United States is increasing.

Psychological adjustment of children with asthma: effects of illness severity and recent stressful life events.

Although children with chronic illness are at greater risk for decreased psychological adjustment than physically healthy children, little is known about the factors that lead to increased risk. Eighty-one children with asthma between the ages of 6 and 14 years and their parents participated in a study to determine the relative contribution of background variables (age, gender, and socioeconomic status), recent stressful life events, and illness severity to psychological adaptation. Overall 11.5% of the children had CBCL Total Behavior Problems scores above the 98th percentile. Multiple regression revealed that lower SES, negative life change, and high illness severity were predictive of less optimal psychological adjustment. The results highlight the need for interventions to improve coping with both disease and nondisease issues.

Improving the psychological status of children with asthma: a randomized controlled trial.

Children with asthma are at special risk for problems in psychological functioning, as are children with other chronic illnesses. We conducted a controlled trial of a combined education and stress management program among children ages 6 to 14 years with asthma. Eighty-one children were randomly assigned to an intervention or a control group; 56 children completed data collection, 29 intervention and 27 control. Psychological status was assessed by the Child Behavior Checklist (CBCL) before and after the intervention, as were children's knowledge of asthma, stress (as measured by children's life events), and functional status (as indicated by such activities as school attendance, time playing with friends, and daily chore performance). Children in the intervention group had a significant improvement in the total Behavior Problems score (p less than .04) and Internalizing scale (p less than .01) on the CBCL and a significant increase in daily chores (p less than .04) compared with the control group. Before intervention, the two groups had statistically significant positive relationships between negative life events and behavior problems scores. After intervention, children in the control group still demonstrated a significant relationship between negative life events and total and Internalizing Behavior Problem scores, although participation in the intervention group negated that relationship. Children in the intervention group whose knowledge of asthma increased were more likely to report an increase in daily chores (p less than .02). We conclude that the intervention had a beneficial effect on psychological status and on children's daily activities. The effect may have occurred in part by decreasing the likelihood that perceived stress from negative life events led to poorer adjustment.

Foreign medical graduates in rural primary care: the case of western New York State.

To determine whether foreign medical graduates (FMGs) provide a disproportionate and increasing share of primary care in some rural areas, changes in physician distribution in a rural section of upstate New York over a 20-year period (1953-1973) were evaluated by country of medical education and type of practice. A contiguous urban area was examined for comparison. In 1953, FMGs accounted for a higher proportion of primary care physicians in rural areas (11%) than in urban practice (6%) (p less than 0.01). By 1973, this distribution had increased to 26% rural and 14% urban (p less than 0.001). During the two decades, the number of U.S. medical graduates in primary care declined by 15% in the rural areas but increased by 13% in the urban center. The number of primary care FMGs in this same period increased 88% in the rural area. With a 10% decline in (rural) FMGs trained in developed countries, this net increase in FMGs was accounted for by physicians from developing countries. Primary care physicians trained in the U.S. or in developed countries increased more in the urban center, while physicians from developing countries increased more in rural (53%) than urban (47%) practices. Finally, by 1973, rural primary care physicians were more likely than urban primary care physicians to be from developing countries (p less than 0.001).
