PARTICIPANTS AND METHODS. Women who were pregnant or had an infant <12 months old and who were enrolled in East Baltimore's Healthy Start home-visiting program were eligible for the study. For this pilot project, we used a prospective predesign/postdesign. Maternal self-report and investigator home observations documented the use of working smoke alarms on each level of the home, stair gates or doors blocking the top and bottom of all staircases, adult medication storage in locked cabinets, and the environmental feasibility of safety-product use.
RESULTS. Home safety practices were higher by maternal self-report than by investigator observation. Fifty-five percent of families who reported a working smoke alarm on every level of the home had nonworking or absent smoke alarms noted during investigator observation. Of assessed staircases, 67% could not accommodate a wall-mounted gate at the top of the stairs, and 38% could not accommodate a pressure-mounted gate at the bottom of the stairs. Although most families reported locked storage of medications, 77% had unlocked medication storage documented during home observation.
CONCLUSIONS. In this sample of urban families, implementation of American Academy of Pediatrics-recommended safety practices is low. The structural design of urban homes may be a significant barrier to home safety-product use. The American Academy of Pediatrics Injury Prevention Program sheets, manufacturers of safety products, and legislators need to address injury-prevention issues unique to urban, low-income families.

Injuries occurring in the home are common. Recent epidemiologic studies on residential injuries report significant morbidity and mortality in infants and young children.1,2 Data from the National Vital Statistics System 1985–1997 indicate that the highest residential injury mortality rates are in infants <1 year of age (12.6 per 100000); >90% of injury deaths in children <1 year of age occurred in the home.2 Residential injury morbidity is also high. In 1993–1999, data from the National Hospital Ambulatory Medical Care Survey reported >50% of unintentional injury emergency visits for children <20 years of age were because of residential injuries.1 The highest rates were in infants <1 year (6.22 per 100) and children ages 1 to 4 years (9.58 per 100).1
Many residential injuries can be prevented using recommended home safety products such as smoke alarms, stair gates, and cabinet locks.3 However, studies have shown low rates of home safety-product use, especially among low-income families, whose children are at increased risk of unintentional injuries.4–6 In a previous study in urban Baltimore, 55% of families with infants 12 to 18 months of age had
1 working smoke alarm, 25% of families had stairs blocked by gates or doors, and 6% had poisons stored in a locked area.7 Previous studies have found that the prevalence of home safety behaviors was lower by self-report than by observation, but these studies focused on families with older infants and young children.8,9 Although the American Academy of Pediatrics (AAP) recommends instituting anticipatory guidance in the first 6 months of life, and most injuries to infants occur in the home, little is known regarding the prevalence of home safety practices in families with children <1 year of age.1,2,10 To our knowledge, no study has assessed the prevalence of home safety practices in families with infants <12 months of age in the context of the structural design and environmental state of repair of low-income, urban homes. Because the Centers for Disease Control and Prevention Injury Research Agenda places high priority on evaluating the dissemination of home safety practices in low-income populations,11 it is crucial to closely examine these relationships to inform policy and practice.
Our objectives were to describe self-reported and observed home safety practices in low-income families who were expecting or had a child <12 months of age and to assess the feasibility of using safety products depending on the structural design and state of repair of urban homes. Previous research has demonstrated that general housing and neighborhood conditions at both the individual household12 and census tract level13 have been associated with parent safety practices and child injury risk. We hypothesized that the presence of home safety products, such as working smoke alarms, stair gates, and cabinet locks, is low in this urban population, that self-report is higher than observed home safety practices,7 and that the structural design and the state of repair of low-income urban homes are barriers to the appropriate use of home safety products.

The present study was one portion of a larger trial that used a prospective 1-group predesign/postdesign, where each participant served as her own control subject. The home safety protocol intervention consisted of providing home safety information and coupons for home safety products, preintervention and postintervention self-report safety questionnaires, and home observations. This report will focus on data from postintervention data collection. Recruitment and enrollment began in April 2005, and data collection was completed in January 2006. Enrollment took place at the Healthy Start Neighborhood Center or in the participants' homes. Informed consent was obtained from all of the participants. The study was approved by the Johns Hopkins School of Medicine Institutional Review Board and the Baltimore City Health Department Human Subjects Review Committee.
Study Participants
Women who were pregnant or who had an infant <12 months old and were current East Baltimore Healthy Start clients were eligible for the study. All of the participants were biological mothers. Recruitment occurred by neighborhood health advocates' invitation, mass mailing to all eligible Healthy Start clients, and fliers posted in the East Baltimore Healthy Start Neighborhood Center. We excluded women who were not the primary caretaker of their infant, those <16 years old, and those who lived with another study participant. Participants received electric outlet covers and $15 remuneration for each of 2 interviews completed during the study.
Data Collection
Demographic information was gathered during enrollment and from Healthy Start records. Home safety information was obtained first by a parent self-report questionnaire, and then the investigator home observation was scheduled and completed. We attempted to have <1 week between the completion of the questionnaire and the home observation. The self-report questionnaire was administered in the home or by telephone by either the principal investigator or a trained research assistant. The questionnaire was piloted previously and used in the same population (S. Tandon, PhD, written communication, 2005). The investigator observation checklist was modified from the home safety assessments of Gielen et al9 and Johnston et al14 by choosing existing questions pertaining to fire, fall, and poisoning prevention, and items on staircase width and design were added. The staircase-design observations were piloted on Healthy Start clients who were not study participants. The principal investigator (Dr Stone) completed each home observation by directly observing home safety practices, home structural design, and home environment state of repair. Data were double entered into a database by the principal investigator and a trained assistant. All of the analyses were conducted using SPSS 11.0 (SPSS Inc, Chicago, IL) and Stata 8 (Stata Corp, College Station, TX).
Outcome Measures
The self-report questionnaire assessed the following home safety practices: part 1: (a) presence of a smoke alarm, (b) presence of a working smoke alarm on every level of the home, and (c) the number of months since smoke alarm batteries were changed; part 2: (a) presence of staircases and (b) the use of gates or doors to block the top and bottom of each staircase; and part 3: (a) presence of adult medications and (b) locked storage of all adult medications. The investigator observation assessed the following home safety practices: (a) number and location of smoke alarms and demonstration of whether each worked; (b) presence of staircases and presence and use of gates or doors to block the top and bottom of all staircases, and (c) presence of adult medicines, location of medication storage, and storage in a locked area.
We assessed staircase structural design issues including the width of top and bottom of staircases and banister design to determine feasibility of stair gate installation. To use a stair gate correctly, the width of the opening at the top of the stairs must be
28 inches to accommodate a wall-anchored stair gate, and the width at the opening at the bottom of the stairs must be
26 inches wide to use a pressure-mounted gate. The staircase must have a flat surface on both sides to which the gate can be anchored.
The environmental state of repair was observed for the 3 risk areas: (1) fire risk (exposed wires or outlets and use of alternative heat or light sources such as candles, gas stoves, or space heaters); (2) fall risk (broken stairs, railings, and banisters); and (3) ingestion risk (broken cabinet hinges and doors). We chose these outcomes on the basis of input from the neighborhood health advocates and their first-hand observation of environmental disrepair, the history of fires in this community resulting from inappropriate use of alternative heat and light sources in homes with no gas or electricity, and personal observation by the principal investigator (Dr Stone) during previous home visits conducted during clinical care.

Self-report of the presence of adult medications in the home was lower than was noted during the investigator home observation (Table 2). In addition, whereas 71% of families reported storing medications in a locked area, only 17% had locked medication cabinets found during the home observation. Medication storage areas observed during the home visit included unlocked medicine cabinets, purses, and the top of the refrigerator or high shelves.
Home Structural Design
When the width of staircases and banister design were considered together, only 35% of homes had staircases that could accommodate a wall-mounted gate at the top of the stairs, and 62% of homes had staircases that could accommodate a pressure-mounted gate at the bottom of the stairs (Table 3).

In this pilot project, the prevalence of appropriate home safety-product use was low, indicating that these children were inadequately protected against fires, falls, and poisonings. Families had received injury-prevention information as a part of the home safety protocol. It is possible that the families did not read this information, were unable to implement the recommendations, or this anticipatory guidance is ineffective in low-income, urban populations. Although not specifically studied, mothers may believe that their children are not at risk of injury, or financial constraints may limit families' abilities to purchase tools to install safety supplies. Because many families live with friends or relatives, they may be unable to make changes to improve the safety of their homes.
Although a smoke alarm was found in 97% of the homes, only half of the participants had a working smoke alarm on each level of the home. Previous studies in Baltimore found a similar prevalence of working smoke alarms,12 which suggests that urban Baltimore families have difficulty maintaining smoke alarms after they are installed. These findings support those of the randomized, controlled smoke detector giveaway program by DiGuiseppi et al15,16 in Great Britain, in which few of the smoke detectors had been installed or maintained at follow-up visits. Our findings indicate that there are barriers to smoke detector use beyond the purchase of smoke alarms. The high ceilings of many homes may make changing smoke alarm batteries impossible without a ladder, or the cost of batteries may be a barrier to maintaining smoke alarms. To address these issues, advocating for the inclusion of long-life lithium batteries in new smoke alarm installations or requiring landlords to test and maintain smoke alarms may increase appropriate smoke alarm use.
Our rate of appropriately protected staircases was lower than previous studies in urban Baltimore families.7,9,12 This pilot study provides the first descriptive data regarding the feasibility of stair gate use in urban homes. Despite the small sample size, it is likely that this is a problem in much of urban Baltimore, given the uniformity of row-home housing, and may be relevant in other parts of the country. Current strategies to address ill-fitting gates, such as nailing plywood across banisters or using play yards, which confine the child to one spot in a room, may not be feasible for many families. One study in Philadelphia, Pennsylvania, found that 21% of homes had staircases with broken or loose railings.17 Improved housing codes and the manufacture of gates designed to fit narrow staircases are needed.
Consistent with other studies, few families stored medications locked.7,9,12 This may be because of the young age of the index child, but this is also concerning, because most families had an older child. In addition, the AAP Injury Prevention Program guidelines recommend instituting poisoning prevention practices in the first 6 months of an infant's life. It is also possible that because most participants rented or lived in the home of a friend or relative, they were unable to install cabinet locks or they perceived existing, unlockable medicine cabinets as appropriate storage areas.
It is concerning that families tend to overestimate their adoption of recommended home safety practices. Parents may overreport safety-product use because of lack of knowledge, fear of neglect charges, or social desirability. Because of the current emphasis on patient-centered primary care, where discussions are tailored to the concerns and needs of the family, certain injury-prevention issues may be omitted if the family confidently asserts that their home is "infant proofed."18 Recommending review of certain core "safety practices" at all visits will ensure families have needed injury-prevention information. Tailoring anticipatory guidance about injury prevention to specifically address the possible housing and safety issues prevalent in low-income, urban areas is needed. The AAP recommends initiating injury-prevention counseling in the first 6 months of life to promote home safety practices and prevent injuries.7,19,20 The Injury Prevention Program handouts for children ages 0 to 4 years of age target fire safety, falls, and medication storage by promoting installation of smoke alarms, changing of smoke alarm batteries, and use of stair gates and cabinet locks.7,19,20 Modifying the Injury Prevention Program sheets to sensitively address the housing and injury-prevention issues unique to low-income urban families would have the potential to reach many families.
There is increasing interest in the role of the built environment in children's health; thus, it is timely and crucial for child health advocates to continue the line of research started here. Lyons et al21 reported recently about the differences in injuries found in different types of housing. This report found a higher prevalence of injuries in apartment buildings compared with single family homes. Although this report does not comment on the interior structural design or state of repair of housing, the importance of housing design on injury is apparent.
Although there had been progress in improving home safety for children in the past 40 years, there is still much work to be done.22,23 In the 1970s, the success of New York's "Children Can't Fly" campaign in mandating window guards and the Poison Prevention Packaging Act mandating child-resistant medication caps were thought to herald a new era in passive, structural strategies for residential injury prevention.23–26 Regulation, legislation, and policy changes have the potential to significantly decrease injuries, and the Centers for Disease Control and Prevention call for assessing the impact of legislation and policy on residential injuries.11 Requiring long-life lithium batteries in smoke alarms would decrease needed maintenance. Requiring manufacturers to design stair gates that are compatible with urban staircases and requiring installation in rental homes have the potential to decrease serious falls. Mandating landlords to provide medication lock boxes in homes with young children would decrease dependence on unlocked medicine cabinets. As primary care providers and public health professionals, we must continue to advocate for policy to improve home safety, especially in low-income, urban housing.

Because these families were enrolled in a program that provided many resources, they may have had strong advocates that helped them to access improved housing. Possibly those living with friends or relatives had more stable housing situations. This may have resulted in fewer environmental hazards present in their homes but may have decreased the number of participants who were able to install stair gates and cabinet locks. Because consent was required, participants may have been more motivated to repair their homes, potentially causing an underestimation of environmental state of repair. It is likely that environmental hazards are common in this population, and disrepair in urban housing needs to be addressed by developing stricter US Department of Housing and Urban Development criteria and grassroots legislative action.
