Abstract

Objective: Adequate fluoride exposure is especially important for those experiencing disproportionately high prevalence of dental caries, such as rural Latino farmworkers and their children. Water is an important source of fluoride. This qualitative study examined water consumption beliefs and practices among Latino parents of young children in a rural community.

Methods: Focus groups and open-ended in-depth interviews explored parents' beliefs about tap water, beverage preferences, and knowledge of fluoride. A questionnaire documented socio-demographic characteristics and water consumption practices. Qualitative analysis revealed how water-related beliefs, social and cultural context, and local environment shaped participants' water consumption.

Results: The vast majority of participants (n = 46) avoided drinking unfiltered tap water based on perceptions that it had poor taste, smell, and color, bolstered by a historically justified and collectively transmitted belief that the public water supply is unsafe. Water quality reports are not accessible to many community residents, all of whom use commercially bottled or filtered water for domestic consumption. Most participants had little knowledge of fluoride beyond a general sense it was beneficial. While most participants expressed willingness to drink fluoridated water, many emphatically stated that they would do so only if it tasted, looked, and smelled better and was demonstrated to be safe.

Conclusions: Perceptions about water quality and safety have important implications for adequate fluoride exposure. For vulnerable populations, technical reports of water safety have not only to be believed and trusted but matched or superseded by experience before meaningful change will occur in people's water consumption habits.
