Background: the scope of maternity home services for pregnant teenagers across Canada is unknown. We sought to identify and describe ail of the group residential facilities for pregnant women admitting teenagers in Canada, and to develop a profile of the youngest adolescents living therein.Methods: we consulted the social welfare departments of the major cities in each province, enquiring as to the existence of local maternity homes. In turn, maternity homes that were contacted served to help locate additional similar facilities. After a systematic and exhaustive effort, a nationwide roster of maternity homes was assembled. An official at each maternity home was asked to provide information through a postal questionnaire. The collected data were then organized, tabulated, and analysed.Results: we found a total of 28 maternity homes admitting girls under the age of 18 years (range: Ontario 13; Alberta, New Brunswick, and Prince Edward Island (0), and 26 (93%) completed and returned our questionnaire. Licenses from regulatory agencies were held by 22 homes (85% of respondents), girls dependent on illicit drugs or alcohol were admitted by 13 homes (50% of respondents), and the Salvation Army sponsored a total of eight of the 28 maternity homes. Median values for some characteristics were: years in operation, 57; age of youngest current resident, 15 years; typical length of stay, seven months; bed capacity, 14; number of full-time employees, seven; annual deliveries, 16; annual adoptions, two. The most common funding sources were city or provincial public funds as reported by 25 homes (96% of respondents) and the least common was the federal government reported by three homes (12% of respondents). Benefits included: private rooms in 25 homes (96%) ; social work services from 22 homes (85%) ; classes by a certified childbirth educator provided by 16 homes (62%) ; accredited on-site schooling available in 13 homes (50%) ; and vocational training arranged by six homes (23%). Prenatal care through private physicians was reported by 19 homes (73%) and through hospital based prenatal clinics by 17 homes (65%). AH deliveries were conducted in hospitals. A sampling of 48 of the youngest pregnant teenagers served in the past year revealed: median age 15 (range: [13–18]; 32 were white [67%], 11 were Native American [23%], two were African American [4%], two were Hispanic [4%], and one was Asian [2%]). There were 25 alleged victims of sexual abuse (52%) ; 26 alleged victims of physical abuse (54%) ; seven exchanged sex for food and shelter (15%); five exchanged sex for illicit drugs (10%); 13 abused illicit drugs or alcohol (27%) ; 11 had been convicted of a criminal offense (23%) ; none sold illicit drugs. Independent living and parenting skills classes were taken by 44 of the girls (91%).Conclusion: in Canada, group residential placement and services are available to pregnant teenagers who face a variety of serious psychosocial risk factors.
