下载免费PDF全文 Methods—Grade 4 children from six elementary schools in East York (a borough of Metropolitan Toronto) participated. The intervention—playground based instruction on bicycle handling skills by certified instructors—was randomly allocated to three schools. Altogether 141 children participated: 73 in the intervention group and 68 in the control group, with follow up evaluations available on 117 (83%). The primary outcome was safe cycling behavior (straight line riding, coming to a complete stop, and shoulder checking before a left turn). A self report questionnaire collected data on knowledge and attitudes. Baseline assessments were made in June, with follow up evaluations in September, 1995.
Results—The prevalence of safe cycling behaviors at follow up in the intervention and control groups respectively, were: straight line riding (90% v 88%; p=0.782), coming to a complete stop (90% v 76%; p=0.225), and shoulder checking (0% v 2%; p=1.000). Over time (from baseline to follow up) children in both groups were more likely to maintain straight line riding, less likely to ride on the sidewalk, and less likely to consider that a car had more right to the road.
Conclusions—This brief skills training program was not effective in improving safe cycling behavior, knowledge, or attitudes among grade 4 children.
相似文献Study sample—Preschool Head Start programs that conducted routine home visits among their enrolled families at least five times during the school year were eligible. Eighteen sites and 880 children met this criterion and were able and willing to carry out evaluation activities. Two hundred children were from control sites where no helmet promotion activities were carried out.
Intervention—Classroom activities with children, education of parents during school meetings and home visits, fitting and distribution of helmets, a bicycle skills and safety "rodeo" event, and requiring children to wear helmets while riding on school grounds.
Evaluation methods—Regularly scheduled home visits were used to observe helmet use of enrolled preschool children before and after the promotion program. Home visitors requested parental permission for enrolled children to ride, and then noted whether the child wore a helmet.
Results—Helmet use in the intervention group more than doubled, from 43% to 89%, while use in the control group increased from 42% to 60% (p<0.05 for intervention group changes v control group changes).
Conclusions—This multifaceted helmet promotion program successfully increased helmet use. Similar home visit protocols may be useful to evaluate the impact of other injury intervention programs.
相似文献Results—One hundred and fifty four primary caretakers participated. Of these, 77% (n=119) of caretakers used infant walkers for their child. For children who were not first born, 85% of caretakers had used walkers with their other children. No statistically significant differences were found between walker users and non-users with respect to the sex or birth order of the child, race, education, or (type of) caretaker. Also, no differences were found between these groups with respect to having received safety information from the pediatrician. For users, 97% heard about walkers before their baby's birth, but 65% did not decide to use one until after the birth. In addition, 61% of walker users stated that no one influenced their decision to get a walker and 75% bought their own. These decisions were not affected by caretaker education or birth order of the child. Finally, 78% believed that walkers were beneficial, and 72% believed that walker use accelerated development of independent walking skills.
Conclusions—Mothers purchased walkers because of no uniformed perception of benefit. A period of time, up to several months in length, exists from when the first mother hears about walkers until she decides to purchase one. Until legislation can be passed banning walkers, this period of time may provide a window of opportunity for appropriate anticipatory guidance in the form of intense media assisted, antiwalker campaigns.
相似文献Methods—Using 1988–95 data from the United States Fatality Analysis Reporting System, risk of death was compared among front and rear seated passengers aged 12 and younger who were involved in fatal crashes for different categories of restraint use and in vehicles with and without passenger airbags.
Results—Restrained children in rear seats had the lowest risk of dying in fatal crashes. Among children seated in the rear, risk of death was reduced 35% in vehicles without any airbags, 31% in vehicles equipped only with driver airbags, and 46% in vehicles with passenger airbags. Both restrained and unrestrained children aged 0–12 were at lower risk of dying in rear seats. Rear seats also afforded additional protection to children aged 5–12 restrained only with lap belts compared with lap/shoulder belted children in front seats. Children were about 10–20% less likely to die in rear center than in rear outboard positions.
Conclusions—Parents and others who transport children should be strongly encouraged to place infants and children in rear seats whether or not vehicles have airbags. Existing laws requiring restraint use by children should be strengthened and actively enforced.
相似文献Methods—Mail survey of participants in a Sacramento, California gun exchange program, August 1993; the response rate was 79%. Comparative data were obtained from nationwide polls of gun owners.
Results—Most (62%) respondents were men; 40% were more than 55 years old; none was less than 25. Concern that children might find and use the gun was the most frequently cited reason for participating (46% of respondents). Of 141 firearms exchanged, 72% were handguns; 23% of respondents indicated that the guns they turned in were not in working order. Of respondents who owned a gun at the time of the program (rather than those who owned no guns and turned in a gun owned by someone else), 41% owned no guns after participating; the prevalence of handgun ownership declined from 79% to 32%. Those who continued to own guns were as likely as gun owners nationwide to keep a gun loaded in the house (odds ratio (OR) 0.9, 95% confidence interval (CI) 0.4 to 1.7) or to carry a gun with them (OR 1.5, 95% CI 0.6 to 3.8).
Conclusions—Gun exchange programs may reduce risk for firearm violence among some participants, but a number of factors limit their overall benefits to host communities.
相似文献Methods—Questionnaire administered to a convenience sample of grade 6 students attending an agricultural fair.
Results—162 grade 6 children participated. The mean age was 11.4 years, and 46% were male. 125 students (77%) reported having access to ATVs, including 69 four wheeled, 24 three wheeled, and four both three and four wheeled ATVs. ATV experience was reported in 95 students, significantly more often in males and among those with a family owned ATV, with no difference between children living on a farm and in a town. Use of helmets and protective clothing was inadequate (10–40%), and dangerous riding habits common, with males and children living on a farm reporting significantly fewer desirable behaviours.
Conclusions—ATVs are commonly used by children in rural Manitoba, with inadequate protective gear and dangerous riding habits. Mandatory rider training, consumer and dealer education, and legislation enforcement could improve ATV safety in this population.
相似文献DESIGN—A randomised controlled trial, with blind assessment of outcome status. Parents of children due for their first measles vaccination were randomised to one of two groups, one receiving the health belief model reminder card, the other receiving the usual, neutrally worded card. The proportion of children subsequently vaccinated in each group over a five week period was ascertained from clinical (provider based) records.
SETTING—A local government operated public vaccination clinic.
PARTICIPANTS—Parents of 259 children due for measles vaccination.
MAIN RESULTS—The proportion of children vaccinated in the health belief model card group was 79% compared with 67% of those sent the usual card (95% CI, 2% to 23%), a modest but important improvement.
CONCLUSION—This study illustrates how the effectiveness of a minimal and widely practised intervention to promote vaccination compliance can be improved with negligible additional effort.

Design—Injuries were prospectively recorded over the four year period from 1992–95 in a cohort of children aged 0–12 years, representing 193 540 children years. Information about length and extent of activity restriction was collected from parents by a mailed questionnaire for a subsample of 192 children with a fracture.
Results—A total of 2477 fractures occurred in the study population (128 per 10 000 children annually). The incidence increased linearly with age, by 14 cases per 10 000 children year for each year of age. Boys and girls showed similar patterns of fracture occurrence. There was a significant difference in length of activity restrictions for different types of fractures. The mean and 95% confidence interval (CI) of activity restricted days for leg fractures were 26 (95% CI 7 to 45) days, for arm fractures, 14 (95% CI 8 to 20) days, and for other fractures, 5 (95% CI 1 to 8) days. Arm fractures represented 66% of the cases and 62% of the activity restricted days; leg fractures 19% of cases and 33% of all activity restricted days; and other fractures 16% of the cases but only 5% of the activity restricted days in this population.
Conclusion—The incidence of fractures increases in childhood. Different types of fractures among children cause different amounts of activity restriction.
相似文献 下载免费PDF全文 Setting—The target area was a 24 square mile (62 km2) section on the south side of Oklahoma City where 16% (73 301) of the city's population resided in 16% (34 845) of the dwellings (excluding apartments). Of the 66 persons in Oklahoma City who were injured in residential fires from September 1987 to April 1990, 45% (30) were in the target area. Of the target area injuries, 47% resulted from fires started by children playing with fire (fireplay).
Methods—The number of homes without detectors was estimated by telephone survey. Four different methods of soliciting participants were used, including notifying residents by mail; placing flyers on the doors of every habitable residence; and displaying flyers at public places (grocery stores, convenience stores, restaurants, etc). Each of these methods alerted residents that free smoke detectors were available at specific fire stations. The fourth method was distributing detectors door-to-door (canvassing).
Results—The canvassing method resulted in significantly more smoke detectors being distributed to homes without detectors (107%) than any of the three other methods (18%) (p< 0.00001). The canvassing method distributed detectors to 31% of the total target homes, compared with 5% with the other methods (p < 0.00001). Canvassing also resulted in the lowest estimated cost per detector distributed ($1.96) (all other methods, $3.95), and in the largest number distributed per volunteer hour (5.9 v 3.1 detectors per hour by other methods).
Conclusions—Distributing smoke detectors directly to homes (canvassing) was the most effective and cost efficient method to reach high risk urban residents.

Setting—The Norwegian city of Harstad (main intervention), six surrounding municipalities (intervention diffusion), and Trondheim (reference).
Participants—Children under age 5 years in the three study populations.
Methods—Outpatient and inpatient hospital data were coded according to the Nordic system, and collected as part of a national injury surveillance system. Burn data collection started in May 1985. The first 19.5 months of the study provided baseline data, while the last 10 years involved community based intervention, using a mix of passive and active interventions.
Results—The mean burn injury rate decreased by 51.5% after the implementation of the intervention in Harstad (p<0.05) and by 40.1% in the six municipalities (not significant). Rates in the reference city, Trondheim, increased 18.1% (not significant). In Harstad and the six surrounding municipalities there was a considerable reduction in hospital admissions, operations, and bed days. Interventions with passive strategies were more effective, stove and tap water burns being eliminated in the last four years, while active strategies were less effective.
Conclusions—A program targeting burns in children can be effective and sustainable. Local injury data provided the stimulus for community action.

Methods—An ecologic study design was used with census block groups as the unit of analysis. Measures of neighborhood poverty, household crowding, and acculturation were specific to each ethnic group. Poisson regression was used to calculate mutually adjusted incidence rate ratios (IRRs) corresponding to a 20% difference in census variables.
Results—Among non-Hispanic white children, injury rates were more closely associated with neighborhood levels of household crowding (adjusted IRR 2.36, 95% confidence interval (CI) 1.22 to 4.57) than with neighborhood poverty (adjusted IRR 1.06, 95% CI 0.89 to 1.26). For Hispanic children, the strongest risk factors were the proportion of Hispanic adults who spoke only some English (compared with the proportion who spoke little or no English, adjusted IRR 1.26, 95% CI 1.04 to 1.53) and the proportion who were US residents for <5 years (adjusted IRR 1.20, 95% CI 1.001 to 1.43). Neighborhood levels of household crowding were not related to injury among Hispanic children (adjusted IRR 0.98, 95% CI 0.89 to 1.08), but surprisingly, neighborhood poverty was associated with lower injury rates (adjusted IRR 0.89, 95% CI 0.81 to 0.97).
Conclusions—Cultural and geographic transitions, as well as socioeconomic differences, appear to contribute to differences in childhood injury rates between ethnic groups.
相似文献OBJECTIVES—To assess if a dietary health education programme could be used within existing health resources to reduce the incidence of iron deficiency anaemia in an inner city population.
DESIGN—Prospective cohort study.
SETTING—Inner city areas of west and south Birmingham.
SUBJECTS—A total of 1000 children recorded on the child health computer register.
INTERVENTION—Children were recruited at birth and randomised into control and intervention groups. Families in the intervention group received specific health education information at key ages by face to face contact using a range of materials. The control group received standard health education as delivered by the health visitors at the time.
MAIN OUTCOME MEASURES—Haemoglobin estimation and iron content of the diet at 18 months of age.
RESULTS—A total of 455 children completed the study. Sixty nine (27%) of the control group and 55 (28%) of the intervention group were anaemic as defined by haemoglobin less than 110 g/l. There was no difference in the iron content of the diets offered to the two groups of children.
CONCLUSION—In this deprived population we have shown no reduction in anaemia using a targeted nutritional programme and have highlighted the difficulties in conducting health education programmes within the scope of current health resources.

Method—A survey was conducted with 421 children aged 7–13 years. The survey asked children whether they carried out specific home activities involving hot water, fire, or appliances that carry a burn risk. It also measured their knowledge of the three basic fire safety messages taught to New Zealand schoolchildren by the fire service.
Results—The results showed that although involvement levels increased with age, the majority of even the youngest children reported carrying out a number of the risky activities, such as preparing hot drinks, running their own baths, or using a microwave without help. No gender differences were found in the number of risky activities engaged in. Significant ethnic differences were found, with higher risk involvement by indigenous Maori and children of Pacific Island descent than children of European or Asian descent. Each of the three fire safety messages were correctly identified by between 79%–91% of the children.
Conclusions—Investigation of children's involvement in household activities that carry an injury risk may help in the design of prevention strategies, including school based education. Prevention efforts need to acknowledge the ages at which children begin to undertake specific household tasks, including those that involve care for younger siblings, and be attuned to the needs of different ethnic groups.
相似文献 下载免费PDF全文 Methods—A population based case-control study was undertaken in a region of Melbourne, Australia. Cases were children presenting at hospital emergency departments with injuries received while riding bicycles. Controls were recruited by calling randomly selected telephone numbers. Data were collected by personal interview.
Results—Analysis, based on 148 cases and 130 controls aged 9 to 14 years, showed no evidence of a protective effect and suggested a possible harmful effect of exposure to the bicycle safety course (odds ratio (OR) 1.64, 95% confidence interval (CI) 0.98 to 2.75). This association was not substantially altered by adjustment for sex, age, socioeconomic status, and exposure, measured as time or distance travelled. Subgroup analysis indicated that the association was strongest in boys (OR 2.0, 95% CI 1.1 to 3.8), younger children, children from families with lower parental education levels, and children lacking other family members who bicycle.
Conclusions—It is concluded that this educational intervention does not reduce the risk of bicycle injury in children and may possibly produce harmful effects in some children, perhaps due to inadvertent encouragement of risk taking or of bicycling with inadequate supervision.
相似文献 下载免费PDF全文 Design—Ecological cross sectional study using data on 51 countries.
Main outcome measures—The relationship between total mortality rates, unintentional injury mortality rates, and percentage in children 1–14 years of age with gross national product (GNP) per capita.
Results—Unintentional injury mortality rates in children were negatively correlated with GNP per capita. However, by categorising the data, we found some areas of non-correlation: in children 5–14 years in low income versus lower middle income countries, and in all age and gender groups in lower high income versus higher high income countries. A high percentage of total deaths due to injuries was clearest in the lower middle income countries in all age and gender groups.
Conclusions—The changes in child injury mortality in relation to socioeconomic development could be conceptualised as three stages: a stage of high magnitude; a stage of high priority; and a stage of improvement. Most middle income countries are in the high priority stage where both injury mortality rates and injury percentage of total deaths are high.
相似文献 下载免费PDF全文 Setting—Boston and New Orleans, which have no laws regarding child seating location, and Paris, Frankfurt, and Brussels, which for approximately 20 years have had laws requiring children under the ages of 10 or 12 to sit in the rear.
Methods—Observations were made in the first quarter of 1997 at several locations in or near each city. The vehicle seating capacity, total number of occupants, the seating location of adults and children, and driver shoulder belt use were recorded for each vehicle with at least one child. The predictors of a vehicle having a child in the front were estimated using logistic regression.
Results—Data on 5501 children riding in 3778 vehicles were collected. Adjusting for differences in vehicle seating capacity, occupant mix, and driver shoulder belt use, vehicles in the European cities are significantly less likely to have a child in the front seat than vehicles in the American cities.
Conclusions—Cities with no history of laws prohibiting children from sitting in the front, vehicles with low seating capacity, vehicles with no adult (other than the driver) or many child passengers, and unbelted drivers were associated with a higher likelihood of children riding in the front seat. It is feasible for a society to insist, through custom and/or law, that children sit in the back seat.
相似文献 下载免费PDF全文 Setting—One hundred and seventeen playgrounds operated by municipalities or school boards in and around Kingston, Ontario, Canada.
Methods—A regional surveillance database was used to identify children presenting to emergency departments who were injured on public playgrounds; each case was individually matched (by sex, age, and month of occurrence) with two controls—one non-playground injury control, and one child seen for non-injury emergency medical care. Exposure data were obtained from an audit of playgrounds conducted using Canadian and US safety guidelines. Exposure variables included the nature of playground hazards, number of hazards, frequency of play, and total family income. No difference in odds ratios (ORs) were found using the two sets of controls, which were therefore combined for subsequent analysis.
Results—Multivariate analysis showed strong associations between injuries and the use of inappropriate surface materials under and around equipment (OR 21.0, 95% confidence interval (CI) 3.4 to 128.1), appropriate materials with insufficient depth (OR 18.2, 95% CI 3.3 to 99.9), and inadequate handrails or guardrails (OR 6.7, 95% CI 2.6 to 17.5).
Conclusion—This study confirms the validity of guidelines for playground safety relating to the type and depth of surface materials and the provision of handrails and guardrails. Compliance with these guidelines is an important means of preventing injury in childhood.
相似文献STUDY DESIGN—2490 children aged 2 to 59 months presenting to a health centre in rural Ethiopia with fever had their history documented and the following investigations: clinical examination, diagnosis, haemoglobin measurement, and a blood smear for malaria parasites. Clinical findings were related to the presence of malaria parasitaemia.
RESULTS—Malaria contributed to 5.9% of all febrile cases from January to April and to 30.3% during the rest of the year. Prediction of malaria was improved by simple combinations of a few signs and symptoms. Fever with a history of previous malarial attack or absence of cough or a finding of pallor gave a sensitivity of 83% in the high risk season and 75% in the low risk season, with corresponding specificities of 51% and 60%; fever with a previous malaria attack or pallor or splenomegaly had sensitivities of 80% and 69% and specificities of 65% and 81% in high and low risk settings, respectively.
CONCLUSION—Better clinical definitions are possible for low malaria settings when microscopic examination cannot be done. Health workers should be trained to detect pallor and splenomegaly because these two signs improve the specificity for malaria.

下载免费PDF全文 Methods—A case-control study of pedestrian injuries among Hispanic children. The sample consisted of 98 children 0–14 years of age hospitalized as a result of a pedestrian injury and 144 randomly selected neighborhood controls matched to the case by city, age, gender, and ethnicity. Cases were compared with controls using conditional logistic regression; in the study design the odds ratio (OR) estimates the incidence rate ratio.
Results—The following family and cultural variables were associated with an increased risk of injury: household crowding (OR=2.8, 95% confidence interval (CI) 1.1 to 7.1 for 1.01–1.5 persons per room, compared with ≤ 1.0 persons per room), one or more family moves within the past year (OR 2.2, 95% CI 1.2 to 4.1), poverty (OR 1.9, 95% CI 1.1 to 3.3), and inability of mother (OR 3.6, 95% CI 1.3 to 10) or father (OR 5.6, 95% CI 1.5 to 20) to read well. However, children in single parent households and children whose parents did not drive a car, had less education, or were of rural origin, did not have an increased rate of injury.
Conclusions—These results have implications for childhood pedestrian prevention efforts for low income, non-English speaking Hispanic populations, and perhaps for other immigrant and high risk groups. Prevention programs and materials need to be not only culturally sensitive but also designed for those with limited reading skills. In addition, environmental interventions that provide more pedestrian friendly neighborhoods must be considered.
相似文献Design—A retrospective study of reported cases.
Subjects—Subjects were those who attended selected Victorian hospital emergency departments (n=17) and those admitted for firework related injuries (n=16).
Results—The mean (SD) age of attenders at emergency department between January 1988 and June 1996, was 8.9 (6.2) years and most (88%) were under 18 years of age. Males accounted for 71% of the cases. The most common anatomical sites and types of injury were head (47%) and burns (88%), respectively. About 53% of the injuries were caused by firecrackers, the remainder by sparklers and penny bangers. Among those admitted to hospital between July 1987 and June 1996, the mean (SD) age was 22.9 (14.8) years and 50% were under 18 years of age. Males accounted for 87% of the cases. There was a significant difference in mean age between those admitted and not admitted to hospital, the former being significantly older.
Conclusions—Although relatively rare, injuries from fireworks still occur in Victoria after legislative restrictions on their sale in 1985. Consequently, there is a potential risk for injuries among children, particularly from firecrackers. More enforcement of the regulations, education, and parental supervision are needed to prevent injuries from fireworks.
