This four year, qualitative study, will use standard anthropological techniques to examine in-depth, parents behaviors around and beliefs about oral health and dental care needs, especially those targeted at children aged birth to five years.
Study Design & Objectives:
The study will used ethnographic techniques (participant-observation) to study how low-income parents (or other adult family caregivers) in a Hispanic community generally manage children's oral health. This was followed by in-depth interviews with a select sample of caregivers to young children along with a sample of dentists and other health professionals in the study location, preschool teachers, community leaders, County dental advocacy organizations and State-level Medicaid (Denti-Cal) fiscal and policy administrators. :
(a) the nature, range and diversity of parental knowledge and beliefs about oral health and dental care needs for young children especially those from birth to five years of age
(b) how these beliefs relate to the kinds of dental care practices undertaken in the home with respect to children, such as use of bedtime bottles, or tooth brushing.
(c) the relationship between beliefs and practices and (i) expressed willingness and (ii) demonstrated ability of caregivers to seek and use dental services for young children
(d) the impact of family life circumstances (eg, insurance, migrant status, language preference, etc) on parents seeking and using care for children's oral health
(e) how well and why/why not preventative messages and advice given on oral health, especially about Early Childhood Careis, are
(i) accepted and
i (ii) incorporated into oral health practices for young children
(f) differences between rural and urban caregivers’ beliefs, practices and life circumstances that affect children's oral health
Qualitative research - ethnography
One urban (San Jose) and one rural (Mendota) site in Northern California
Data collected 2005-2007; data now in analysis
Study Accrual: Both Sites
95 mothers and 20 fathers of young children
40 community leaders, preschool teachers, oral health advocates, and Denti-Cal regulatory administrators
Inclusion Criteria for Parent/Caregiver Sample:
●Self-identify as Mexican or Latino
●Be first- or second- generation immigrant
●Be low-income with an annual income at or below federal poverty level
● Be the primary caregiver on a daily basis for at least one child aged five or younger
● Be aged 18 years or older
Main Findings (as of December 2008):
1) While parents desire their children to have good oral health, they generally do not recognize early signs of caries in children, nor understand what substances (other than candy) or habits can lead to ECC
2) Parents do not initiate oral hygiene routines as early as recommended by oral health professionals, but do regard tooth brushing as an important habit for children to develop
3) Many low-income Hispanic families in rural areas experience transportation difficulties. This can be a barrier to dental care, especially if specialty care is necessary.
4) Even if municipal water supplies were fluoridated, Hispanics in both the rural and urban area prefer to drink bottled water, believing it to be safer.
5) Parents experience difficulty in accessing dental care for young children, because so few providers accept Medicaid payment. There is also a general shortage of dental providers in rural areas.
6) Access to specialty care providers who accept Denti-Cal insurance is especially difficult.
7) State policy and reimbursement practices shape low-income children's access to oral care and the type of treatment they receive, often resulting in sub-optimal care.
