Objective To study the characteristics of pediatric burn epidemiology in this area.Methods Data of 1 500 pediatric burn patients admitted to the Burn Department of the Second Affiliated Hospital of Kunming Medical University from January 1,2018 to December 31,2022 were collected.The age,sex,time of burn occurrence,type of burn,burn area,burn site,proportion of pediatric burn patients in the same period,length of hospitalization,payment method,hospitalization cost and residence of pediatric burn patients were statistically analyzed.Results The most common time for childhood burns to occur is during early childhood(873 cases,58.2％),with male children more likely to suffer burns compared to female children(male∶female=1.9∶1).The most frequent season for these burns is spring(404 cases,26.9％).Scalding from hot liquids is the primary cause of injury(1211 cases,81.0％).Most childhood burns are classified as moderate severity(945 cases,63.0％).The maximum burn area recorded was 98.0％TBSA,the minimum was 0.1％TBSA,the average burn area was 14.5％TBSA,and the median was 10.0％TBSA.The most common site of burns in children is the trunk(982 cases,23.4％).From 2018 to 2022,the proportion of pediatric burn patients among all burn patients has been decreasing annually(x2=18.852,P＜0.001).The average length of hospitalization for pediatric burn patients was 12.4 days,with an average hospitalization cost of 15667.08 yuan.Most of the families of pediatric burn patients live in county-level areas or below(1 027 cases,68.5％).The severity of the burns,treatment methods,and presence of complications all significantly affect the clinical outcomes of pediatric burns,with statistically significant differences(x2=23.453,P＜0.001).Conclusion Pediatric burn patients exhibit a range of significant characteristics.The majority of these patients are male,with the most common age group being toddlers.Spring has been identified as the season with the highest incidence of burns,while autumn sees relatively fewer cases.Scald injuries from hot liquids are the most common type of burn,with moderate burns being the most prevalent.The average bum area is approximately 14.5％of the total body surface area(TBSA).The limbs and trunk are the most commonly affected areas.In recent years,there has been a noticeable decrease in the proportion of pediatric burn patients,which is attributed to the growing awareness of burn prevention among the general population.

Stroke in the elderly has a high incidence rate and great harm. Strengthening the management of high-risk populations is the key to primary stroke prevention. Disease self-management has a better cost-effectiveness ratio. This article reviews the self-management of the elderly at high risk of stroke from the aspects of current situation, content and influencing factors of self-management.
